The '''Bell OH-58 Kiowa''' is a family of single-engine single-[[Helicopter rotor|rotor]] [[military helicopter]]s used for observation, utility, and direct fire support. It was produced by the American manufacturer [[Bell Helicopter]] and is closely related to the [[Bell 206|Model 206A JetRanger]] civilian helicopter.

The OH-58 was originally developed during the early 1960s as the ''D-250'' for the [[Light Observation Helicopter]] (LOH). While the rival [[Hughes OH-6 Cayuse]] was picked over Bell's submission in May 1965, the company refined its design to create the Model 206A, a variant of which it successfully submitted to the reopened LOH competition two years later. The initial model, designated by the service as the ''OH-58A'', was introduced in May 1969. Successive models would follow, often with uprated engines, enhanced protection systems, and other improvements, culminating in the ''OH-58F''. Additional improvements, such as the ''OH-58X'', were proposed but ultimately not pursued.

During the 1970s, the US Army became interested in pursuing an advanced scout helicopter, for which the OH-58 would be further developed, evaluated, and ultimately procured as the ''OH-58D Kiowa Warrior''. The OH-58D is equipped to perform armed reconnaissance missions and to provide fire support to friendly ground forces; it is equipped with a distinctive Mast Mounted Sight (MMS) containing various sensors for target acquisition and laser designation. Another visible feature present on most OH-58s are knife-like extensions above and below the cockpit that form part of the passive [[wire strike protection system]]. The early-build OH-58s were equipped with a two-bladed main rotor, while the OH-58D and newer variants have a four-bladed rotor.

The OH-58 was primarily produced for the [[United States Army]]. Only two months after the type's entry to service, it was first deployed into the [[Vietnam War]]. The US Army would make extensive use of various OH-58 models across numerous war zones over the decades, seeing active combat during the [[Gulf War]], the [[United States invasion of Panama|Invasion of Panama]], and the [[War in Afghanistan]] among others. During 2017, the US Army opted to withdraw its remaining OH-58s, making use of alternative rotorcraft, such as the [[Boeing AH-64 Apache]] and [[Eurocopter UH-72 Lakota]], as well as increasing use of [[unmanned aerial vehicle]]s (UAVs), to fill the role. Furthermore, the OH-58 has been exported to [[Austria]], Canada, [[Croatia]], the [[Dominican Republic]], [[Taiwan]], [[Saudi Arabia]], and [[Greece]]. It has also been [[licensed production|produced under license]] in Australia.

==Development==
===Light Observation Helicopter (LOH)===
On 14 October 1960, the [[United States Navy]] approached 25 helicopter manufacturers to request on behalf of the Army the submission of proposals for a [[Light Observation Helicopter]] (LOH). [[Bell Helicopter]] was one of the manufacturers approached, and chose to enter the competition along with 12 other manufacturers, including [[Hiller Aircraft]] and [[Hughes Helicopters|Hughes Tool Co., Aircraft Division]].<ref>{{cite web |last= Remington |first= Steve |url= http://www.collectair.com/cessna.html |title= The Cessna CH-1 Helicopter |publisher= CollectAir.com |archive-url= https://web.archive.org/web/20090621043635/http://www.collectair.com/cessna.html |archive-date= 21 June 2009}}</ref> Bell's design was internally referred to as the ''D-250'', and would be officially designated as the ''[[Bell YOH-4|YHO-4]]''.<ref name="LOH-1">{{cite web |last= Beechy |first= Robert |url= http://fire.prohosting.com/hud607/uncommon/reference/usa/army.html |title= U.S Army Aircraft Acquisition Programs |archive-url= https://web.archive.org/web/20061118064815/http://fire.prohosting.com/hud607/uncommon/reference/usa/army.html |archive-date= 18 November 2006 |publisher= Uncommon Aircraft 2006 |date= 18 November 2005 |access-date= 19 September 2006}}</ref> On 19 May 1961, Bell and Hiller were announced as winners of the design competition.<ref>''See [[Light Observation Helicopter]]''.

[[File:Oh4a002.jpg|thumb|right|YOH-4A LOH in flight]]
Bell developed the D-250 design into the ''Model 206'', while the HO-4 designation was changed to ''YOH-4A'' in 1962, and produced five prototype aircraft for the Army's test and evaluation phase. On 8 December 1962, the first prototype performed its [[maiden flight]].<ref name="1000photos-1">{{cite web |last= Visschedijk |first= Johan |url= http://www.1000aircraftphotos.com/HistoryBriefs/Bell206.htm |title= Bell 206 JetRanger |archive-url= https://web.archive.org/web/20060914180524/http://www.1000aircraftphotos.com/HistoryBriefs/Bell206.htm |archive-date= 14 September 2006 |publisher= 1000AircraftPhotos.com |date= 16 October 2003 |access-date= 19 September 2006}}</ref> The YOH-4A was also called the ''Ugly Duckling'' in comparison to other contending aircraft.<ref name="1000photos-1"/> After a fly off of the Bell, Hughes and Fairchild-Hiller prototypes, the [[Hughes OH-6 Cayuse]] was selected in May 1965.<ref>Spenser, Jay P. "Bell Helicopter". ''Whirlybirds, A History of the U.S. Helicopter Pioneers'', p. 263. University of Washington Press, 1998. {{ISBN|0-295-98058-3}}.</ref>

When the YOH-4A was rejected by the Army, Bell went about solving the problem of marketing the aircraft. In addition to the image problem, the helicopter lacked cargo space and only provided cramped quarters for the planned three passengers in the back. The solution was a fuselage redesigned to be more sleek and aesthetic, adding {{convert|16|ft3|m3|abbr=off|lk=off}} of cargo space in the process.<ref name="aastad">{{cite magazine |last= Aastad |first= Andy |url= http://rotormagazine.org/Portals/24/pdf/winter2006_7/32.pdf |title= The Introduction to the JetRanger |archive-url= https://web.archive.org/web/20080910202517/http://rotormagazine.org/Portals/24/pdf/winter2006_7/32.pdf |archive-date= 10 September 2008 |magazine= Rotor Magazine |publisher= Helicopter Association International |date= Winter 2006–2007 |access-date= 29 April 2008}}</ref> The redesigned aircraft was designated as the ''Model 206A'', and Bell President Edwin J.

===Advanced Scout Helicopter===
[[File:OH-58A Kiowa US Army in flight.jpg|thumb|OH-58 Kiowa]]

In the 1970s, the U.S. Army began evaluating the need to improve the capabilities of their scout aircraft. Anticipating the [[AH-64 Apache|AH-64A]]'s replacement of the venerable [[AH-1 Cobra|AH-1]], the Army began shopping the idea of an Aerial Scout Program to stimulate the development of advanced technological capabilities for night vision and precision navigation equipment. The stated goals of the program included prototypes that would: <blockquote>...possess an extended target acquisition range capability by means of a long-range stabilized optical subsystem for the observer, improved position location through use of a computerized navigation system, improved survivability by reducing aural, visual, radar, and infrared signatures, and an improved flight performance capability derived from a larger engine to provide compatibility with attack helicopters.<ref name="cmh-1972-05">{{cite book |last= Cocke |first= Karl E. |chapter-url= http://www.history.army.mil/books/DAHSUM/1972/ch05.htm |chapter= V Force Development |url= http://www.history.army.mil/books/DAHSUM/1972/index.htm#Contents |title= Department of the Army Historical Summary |publisher= [[United States Army Center of Military History]] |year= 1972 |access-date= 17 January 2014 |archive-url= https://web.archive.org/web/20130602204630/http://www.history.army.mil/books/DAHSUM/1972/index.htm#Contents |archive-date= 2 June 2013 |url-status= live}}</ref></blockquote>

During March 1974, the Army created a special task force at [[Fort Knox]] to develop the system requirements;<ref name="cmh-1974-11">{{cite book |chapter-url= http://www.history.army.mil/books/DAHSUM/1974/ch11.htm |chapter= XI Research, Development and Acquisition |url= http://www.history.army.mil/books/DAHSUM/1974/index.htm#Contents |title= Department of the Army Historical Summary, 1974 |access-date= 14 April 2007 |publisher= [[United States Army Center of Military History]] |first= Karl E. |last= Cocke |year= 1978 |archive-url= https://web.archive.org/web/20071214152124/http://www.history.army.mil/books/DAHSUM/1974/index.htm#Contents |archive-date= 14 December 2007 |url-status= live}}</ref> by the following year, the task force had devised the requirements for an Advanced Scout Helicopter (ASH) program. The requirements were formulated around an rotorcraft capable of performing in day, night, and adverse weather, and compatible with all advanced weapons systems planned for development and fielding into the 1980s. The program was approved by the System Acquisition Review Council and the Army prepared for competitive development to begin the next year.<ref name="cmh-1975-10">{{cite book |chapter-url= http://www.history.army.mil/books/DAHSUM/1975/ch10.htm |chapter= X Research, Development and Acquisition |title= Department of the Army Historical Summary, 1975 |publisher= [[United States Army Center of Military History]] |url= http://www.history.army.mil/books/DAHSUM/1975/index.htm#Contents |first= Karl E. |last= Cocke |year= 1978 |archive-url= https://web.archive.org/web/20071214152112/http://www.history.army.mil/books/DAHSUM/1975/index.htm#Contents |archive-date= 14 December 2007 |url-status= live}}</ref> However, as the Army tried to get the program off the ground, Congress declined to provide funding in the fiscal year 1977 budget and the ASH Project Manager's Office (PM-ASH) was closed on 30 September 1976.<ref name="cmh-1976-10">{{cite book |chapter-url= http://www.history.army.mil/books/DAHSUM/1976/ch10.htm |chapter= Research, Development and Acquisition |title= Department of the Army Historical Summary, 1976 |access-date= 14 April 2007 |publisher= [[United States Army Center of Military History]] |first= Karl E. |last= Cocke |year= 1977 |archive-date= 14 May 2008 |archive-url= https://web.archive.org/web/20080514042454/http://www.history.army.mil/books/DAHSUM/1976/ch10.htm |url-status= dead}}</ref>

While no development occurred for some years, the program survived as a requirement without funding. On 30 November 1979, the decision was made to defer development of an advanced scout helicopter in favor of modifying existing airframes in inventory as a near term scout helicopter (NTSH) option. The development of a mast-mounted sight would be the primary focus to improve the ability to perform reconnaissance, surveillance, and target acquisition missions while remaining hidden behind trees and terrain. Both the UH-1 and the OH-58 were evaluated as NTSH candidates, but the UH-1 was dropped from consideration due to its larger size and ease of detection. The OH-58, on the other hand demonstrated a dramatic reduction in detectability with a Mast-Mounted Sight (MMS).{{Citation needed|date=August 2022}}

On 10 July 1980, the Army decided that the NTSH would be a competitive modification program based on developments in the commercial helicopter sector, particularly Hughes Helicopters' [[MD Helicopters MD 500|Hughes 500D]], which had made major improvements over the OH-6.<ref name="cmh-1980-11">{{cite book |chapter-url= http://www.history.army.mil/books/DAHSUM/1980/ch11.htm |chapter= 11.

===Army Helicopter Improvement Program (AHIP)===
The Army's decision to acquire the NTSH resulted in the "Army Helicopter Improvement Program (AHIP)". Both Bell Helicopter and Hughes Helicopters redesigned their scout aircraft to compete for the contract. Bell offered a more robust version of the OH-58 in their ''Model 406'',<ref name="tri-2">{{cite web |url= http://tri.army.mil/LC/CS/csa/aahist3.htm#AHIP |title= Historic U.S. Army Helicopters |access-date= 14 April 2007 |archive-url= https://web.archive.org/web/20070224030112/http://tri.army.mil/LC/CS/csa/aahist3.htm#AHIP |archive-date= 24 February 2007 |url-status= dead}}</ref> and Hughes offered an upgraded version of the OH-6.

Initially intended for attack, cavalry, and artillery roles, the Army only approved a low initial production level and confined the OH-58D's role to field artillery observation. The Army also directed that a follow-on test be conducted to further evaluate it due to perceived deficiencies. On 1 April 1986, the Army formed a task force at Fort Rucker, Alabama, to remedy deficiencies in the AHIP.<ref name="cmh-1986-04"/> During 1988, the Army had planned to discontinue the OH-58D and focus on the LHX; however, Congress approved $138 million to expand the program, calling for the AHIP to operate with the Apache as a hunter/killer team; the AHIP would locate targets and the Apache would destroy them in a throwback to the traditional OH-58/AH-1 relationship.<ref name="cmh-1988-04">{{cite book |chapter-url= http://www.history.army.mil/books/DAHSUM/1988/ch04.htm |chapter= Modernizing and Equipping the Army |url= http://www.history.army.mil/books/DAHSUM/1988/index.htm#Contents |title= Department of the Army Historical Summary, 1988 |publisher= United States Army Center of Military History |year= 1993 |first= William Joe |last= Webb |access-date= 30 June 2010 |archive-url= https://web.archive.org/web/20100921164855/http://www.history.army.mil/books/DAHSUM/1988/index.htm#Contents |archive-date= 21 September 2010 |url-status= live}}</ref>

The Secretary of the Army directed instead that the aircraft's armament systems be upgraded, based on experience with Task Force 118's performance operating armed OH-58Ds in the Persian Gulf in support of [[Operation Prime Chance]], and that the type be used primarily for scouting and armed reconnaissance.<ref name="cmh-1989-11">{{cite book |chapter= 11.

== Design ==
[[File:Cobra and Kiowa DF-ST-86-10445.JPEG|thumb|right|OH-58 with AH-1 Cobra in June 1985]]

The Bell OH-58 Kiowa is a family of single-engine single-[[Helicopter rotor|rotor]] [[military helicopter]]s principally used for observation, utility, and direct fire support. The primary role of the original OH-58A was to identify targets for other platforms, such as the [[Bell AH-1 Cobra]] [[attack helicopter]] and ground [[artillery]]; it lacked any armaments and weighed 1,451&nbsp;kg (3,200&nbsp;lb) when fully loaded, being able to carry a small amount of cargo or up to two passengers.<ref name= "flight cutaway2010"/> While initial examples were reliant on the crew to conduct observations, later models were furnished with sophisticated sensors to precisely determine a target's location. Payload capacity was also increased considerably on later-build rotorcraft, the OH-58D Kiowa was designed to carry a maximum load of 2,495&nbsp;kg, 72% more capacity than the original version.<ref name= "flight cutaway2010"/>

Early Kiowas were fitted with a flexible twin-bladed main rotor; starting with the OH-58D, a four-bladed rigid main rotor was used.<ref name= "flight cutaway2010"/> This was entirely composed of [[composite material]]s, the OH-58D was the first US Army rotorcraft to incorporate an all-composite main rotor hub. Later models were outfitted as light [[gunship]]s, being equipped with various armaments, such as [[Stinger]] [[air-to-air missile]]s, a .50-caliber [[machine gun]], podded 70mm [[Hydra rocket]]s and [[AGM-114 Hellfire]] [[air to ground missile]]s.<ref name= "flight cutaway2010"/> Other areas of improvement were the avionics and the cockpit; new navigation and communication systems were installed along with new and larger flight instrumentation, while all light sources were redesigned for compatibility with [[Night vision device|Night Vision Goggle]]s (NVG). Later versions were outfitted with a [[glass cockpit]], which retained conventional instrumentation as a fallback measure.<ref name= "flight cutaway2010"/>

The OH-58D introduced perhaps the most distinctive feature of the Kiowa family — the Mast Mounted Sight (MMS), which resembles a [[beach ball]] perched above the rotor system. The MMS by [[Ball Aerospace & Technologies]] has a gyro-stabilized platform containing a television system (TVS), a [[Thermographic camera|thermal imaging system]] (TIS), and a [[Laser rangefinder|laser range finder]]/[[Laser designator|designator]] (LRF/D).

One distinctive feature of operational OH-58s are the knife-like extensions above and below the cockpit which are part of the passive [[wire strike protection system]]; it protects 90% of the frontal area of the helicopter from wire strikes that can be encountered at low altitudes by directing wires to the upper or lower blades before they can entangle the rotor blade or landing skids. The OH-58 was the first helicopter to test this system, after which the system was adopted by the US Army for the OH-58 and most of their other helicopters.<ref>{{cite web |url= http://magellan.aero/product/wsps/ |title= WSPS |author= Magellan Aerospace |website= magellan.aero |access-date= 1 December 2018 |archive-url= https://web.archive.org/web/20181201222822/http://magellan.aero/product/wsps/ |archive-date= 1 December 2018 |url-status= dead |author-link= Magellan Aerospace}}</ref> Various other defensive and survivability measures were incorporated, such as ballistic floor armor, a [[missile warning system]], crashworthy seats, and [[infrared]] suppression systems for the engine exhaust.<ref name= "flight cutaway2010"/>

==Operational history==
In May 1969, the first OH-58A Kiowa was officially received at a ceremony held at Bell Helicopter's Fort Worth plant, officiated by Major General [[John Norton (soldier)|John Norton]], commanding general of the Army Aviation Materiel Command (AMCOM).<ref>{{cite web |url= http://www.quad-a.org/Hall_of_Fame/personnel/norton.htm |title= Army Aviation Hall of Fame: Lieutenant General John Norton |archive-url= https://web.archive.org/web/20090814215925/http://www.quad-a.org/Hall_of_Fame/personnel/norton.htm |archive-date= 14 August 2009 |publisher= Army Aviation Association of America |access-date= 22 October 2008}}</ref> Two months later, on 17 August 1969, production OH-58A helicopters arrived in [[South Vietnam]] for the first time;<ref>{{cite web |url= http://tri.army.mil/LC/CS/csa/aahist2.htm |title= Historic U.S. Army Helicopters |date= 5 October 2005 |url-status= dead |archive-url= https://web.archive.org/web/20030212203929/http://tri.army.mil/lc/cs/csa/aahist2.htm |archive-date= 12 February 2003}}</ref> their deployment was accompanied by a New Equipment Training Team (NETT) comprising personnel from both the US Army and Bell Helicopters.<ref>{{cite web |url= http://www.flyarmy.org/panel/battle/69062700.HTM |title= Bell Helicopter News information |archive-url= https://web.archive.org/web/20081208161654/http://www.flyarmy.org/panel/battle/69062700.HTM |archive-date= 8 December 2008 |publisher= Vietnam Helicopter Pilot's Association |access-date= 22 October 2008}}</ref> Although the Kiowa production contract had replaced the LOH contract with Hughes, the OH-58A did not automatically replace the OH-6A in operations; subsequently, the Kiowa and the Cayuse would continue operating in the same theater until the end of the conflict.

===Vietnam War===
[[File:Australian Army Bell OH-58A Kiowa.jpg|thumb|right|Australian Army OH-58A in South Vietnam, December 1971]]

On 27 March 1970, an OH-58A Kiowa (s/n 68-16785) was shot down over South Vietnam, one of the first OH-58A losses of the war. The pilot, [[Warrant Officer (United States)|Warrant Officer]] Ralph Quick Jr., was flying [[Lieutenant Colonel]] Joseph Benoski Jr. as an artillery spotter. After completing a battle damage assessment for a previous fire mission, the aircraft was damaged by .51 inch (13&nbsp;mm) machine gun fire and crashed, killing both crew members. Approximately 45 OH-58A helicopters were destroyed during the [[Vietnam War]] due to combat losses and accidents.<ref>{{cite web |last= Roush |first= Gary |url= http://www.vhpa.org/heliloss.pdf |title= Helicopter Losses During the Vietnam War |archive-url= https://web.archive.org/web/20081029002005/http://www.vhpa.org/heliloss.pdf |archive-date= 29 October 2008 |date= 29 October 2008 |publisher= VHPA.org |access-date= 4 January 2009}}</ref> One of the last combat losses in the theatre was of an OH-58A (s/n 68-16888) from [[17th Cavalry Regiment (United States)#Units|A Troop, 3-17th Cavalry]], flown by [[First Lieutenant]] Thomas Knuckey. On 27 May 1971, Lieutenant Knuckey was also flying a battle damage assessment mission when his aircraft came under machine gun fire and exploded. Knuckey and his observer, [[Sergeant]] Philip Taylor, both died in the explosion.<ref>{{cite web |url= http://www.armyaircrews.com/kiowa_nam.html |title= Kiowa crewmember line of duty deaths |archive-url= https://web.archive.org/web/20081231224422/http://www.armyaircrews.com/kiowa_nam.html |archive-date= 31 December 2008 |date= 31 December 2008 |publisher= armyaircrews.com |access-date= 4 January 2009}}</ref>

===Operation Prime Chance===
During early 1988, it was decided that armed OH-58D (AHIP) helicopters from the 118th Aviation Task Force would be phased in to replace the SEABAT ([[MH-6 Little Bird|AH-6/MH-6]]) teams of [[160th Special Operations Aviation Regiment|Task Force 160th]] to carry out [[Operation Prime Chance]], the escort of oil tankers during the [[Iran–Iraq War]]. On 24 February 1988, two AHIP helicopters reported to the Mobile Sea Base Wimbrown VII, and the helicopter team ("SEABAT" team after their callsign) stationed on the barge returned to the United States. For the next few months, the AHIP helicopters on the Wimbrown VII shared patrol duties with the SEABAT team on the Hercules. Coordination proved difficult, despite frequent requests from TF-160, the SEABAT team on the Hercules was not replaced by an AHIP detachment until June 1988.<ref name="160-1">{{cite web |url= http://www.nightstalkers.com/history/4.html |archive-url= https://archive.today/20020615003730/http://www.nightstalkers.com/history/4.html |url-status= dead |archive-date= 15 June 2002 |title= Operations EARNEST WILL and PRIME CHANCE |access-date= 25 March 2007 |work= Night Stalker History}}</ref> The OH-58D helicopter crews involved in the operation received deck landing and underwater survival training from the Navy.

In November 1988, the number of OH-58D helicopters that supported Task Force 118 was reduced. However, the rotorcraft continued to operate from the Navy's Mobile Sea Base ''Hercules'', the frigate ''[[USS Underwood (FFG-36)|Underwood]]'', and the destroyer ''[[USS Conolly (DD-979)|Conolly]]''. OH-58D operations primarily entailed reconnaissance flights at night, and depending on maintenance requirements and ship scheduling, Army helicopters usually rotated from the mobile sea base and other combatant ships to a land base every seven to fourteen days. On 18 September 1989, an OH-58D crashed during night gunnery practice and sank, but with no loss of personnel. When the Mobile Sea Base Hercules was deactivated in September 1989, all but five OH-58D helicopters redeployed to the continental United States.<ref name="cmh-1">{{cite book |chapter-url= http://www.history.army.mil/books/DAHSUM/1989/CH6.htm |chapter= 6.

===Gulf War===
During [[Operation Desert Shield]] (the build-up to [[Operation Desert Storm]]) U.S. Army OH-58Ds would exercise alongside USMC AH-1Ws and assist with targeting and laser spotting. However while this tactic worked and was effective, there is little evidence that this tactic was used, likely to a lack of OD-58Ds.<ref name=":1">{{Cite web |title=Gulf War - Air Power Survey, Volume IV - Weapons, Tactics, and Training |url=https://media.defense.gov/2010/Sep/27/2001329817/-1/-1/0/AFD-100927-066.pdf |access-date=9 August 2024 |website=U.S. Department of Defense |pages=232–233}}</ref>[[File:AH-64A Apache advanced attack and OH-58D Kiowa Warrior helicopters of the 101st Airborne Division stand ready at a forward operating base during Operation Desert Storm. - DPLA - a2c75825eac68d1eac450c8079f64ed0.jpg|thumb|right|AH-64A Apache advanced attack and OH-58D Kiowa Warrior helicopters of the 101st Airborne Division stand ready at a forward operating base during Operation Desert Storm]]

During Operation Desert Storm, 130 deployed OH-58D helicopters worked alongside the other Army attack helicopters, 145 [[Bell AH-1 Cobra|AH-1 Cobras]] and 277 [[Boeing AH-64 Apache|AH-64 Apaches]],<ref name=":1" /> and participated in a wide variety of critical combat ground forces mission. During [[Operation Desert Shield]] and [[Operation Desert Storm]], the Kiowas collectively flew nearly 9,000 hours with a 92 percent fully mission capable rate. The Kiowa Warrior had the lowest ratio of maintenance hours to flight hours of any combat helicopter in the war.<ref>{{cite web |title= The End of an Era: OH-58 Kiowa |url= https://www.dvidshub.net/news/204642/end-era-oh-58-kiowa |website= dvidshub.net}}</ref>

The "Army attack helicopters" also worked [[Combined arms|jointly with]] close air support and support aircraft such as the USAF [[A-10A]]s, [[General Dynamics F-16 Fighting Falcon|F-16A/Cs]], [[General Dynamics–Grumman EF-111A Raven|EF-111As]], [[Lockheed EC-130H Compass Call|EC-130H Compass Call]], [[RF-4G Phantom II]] '[[Wild Weasel]],' and [[Northrop Grumman E-8 Joint STARS|E-8 Joint STARS]].<ref name=":1" />

===RAID===
In 1989, Congress mandated that the [[Army National Guard]] would take part in the country's ''[[War on Drugs]]'', enabling them to aid federal, state and local law enforcement agencies with "special congressional entitlements". In response, the Army [[National Guard Bureau]] created the Reconnaissance and Aerial Interdiction Detachments (RAID) in 1992, consisting of aviation units in 31 states with 76 specially modified OH-58A helicopters to assume the reconnaissance/interdiction role in the fight against illegal drugs. During 1994, 24 states conducted more than 1,200 aerial counterdrug reconnaissance and interdiction missions, conducting many of these missions at night.<ref>{{cite book |chapter-url= http://www.history.army.mil/books/DAHSUM/1994/ch05.htm |chapter= 5.

===Operation Just Cause and action in the 1990s===
During [[United States invasion of Panama|Operation Just Cause]] in 1989, a team consisting of an OH-58 and an AH-1 were part of the Aviation Task Force during the securing of [[Fort Amador]] in [[Panama]]. The OH-58 was fired upon by [[Military of Panama|Panama Defense Force]] soldiers and crashed {{convert|100|yd|m|sigfig=1}} away, in the [[Bay of Panama]].

On 17 December 1994, Army [[Warrant Officer (United States)#Army|Chief Warrant Officer]]s (CWO) David Hilemon and Bobby Hall left Camp Page, [[South Korea]] on a routine training mission along the [[Korean Demilitarized Zone|Demilitarized Zone]] (DMZ). Their flight was intended to be to a point known as Checkpoint 84, south of the DMZ "no-fly zone", but the OH-58C Kiowa strayed nearly {{convert|4|mi|km|spell=in|sigfig=1}} into the Kangwon Province, inside [[North Korea]]n airspace, due to errors in navigating the snow-covered, rugged terrain. The helicopter was shot down by North Korean troops and CWO Hilemon was killed. CWO Hall was held captive and the North Korean government insisted that the crew had been spying. Five days of negotiations resulted in the North Koreans turning over Hilemon's body to U.S. authorities. The negotiations failed to secure Hall's immediate release. After 13 days in captivity, Hall was freed on 30 December, uninjured.<ref>{{cite web |author= Office of the Assistant Secretary of Defense (Public Affairs). |url= http://www.defenselink.mil/releases/release.aspx?releaseid=317 |title= OH-58C Helicopter Down in North Korea |archive-url= https://web.archive.org/web/20070515041754/http://www.defenselink.mil/releases/release.aspx?releaseid=317 |archive-date= 15 May 2007 |publisher= United States Department of Defense |date= 19 December 1994 |access-date= 30 December 2007}}</ref><ref>{{cite web |last= Miles |first= Donna |url= http://www.army.mil/soldiers/feb95/p4.html |title= Drama Along the DMZ |publisher= Soldiers |date= 4–5 February 1995 |access-date= 3 November 2006 |archive-url= https://web.archive.org/web/20060207143301/http://www.army.mil/soldiers/feb95/p4.html |archive-date= 7 February 2006}}</ref>

===Retirement===
The U.S. Army's first attempt to replace the OH-58 was the [[RAH-66 Comanche]] of the [[Light Helicopter Experimental]] program, which was canceled in 2004. Airframe age and losses led to the Armed Reconnaissance Helicopter program and the [[Bell ARH-70]], which was canceled in 2008 due to cost overruns. The third replacement effort was the [[Armed Aerial Scout]] program.<ref name="aas forward">{{cite web |url= https://www.reuters.com/article/us-army-helicopter-idUSBRE8B002T20121201?feedType=RSS&feedName=everything&virtualBrandChannel=11563 |title= U.S. Army officials said to back new scout helicopter |archive-url= https://web.archive.org/web/20150924172340/http://www.reuters.com/article/2012/12/01/us-army-helicopter-idUSBRE8B002T20121201?feedType=RSS&feedName=everything&virtualBrandChannel=11563 |archive-date= 24 September 2015 |publisher= Reuters.com |date= 30 November 2012}}</ref> Due to uncertainty in the AAS program and fiscal restraints, the OH-58F's planned retirement was extended from 2025 to 2036.<ref name=AW_slep>{{cite web |url= http://www.aviationweek.com/Article.aspx?id=/article-xml/awx_05_10_2013_p0-577834.xml&p=1 |title= U.S. Army Confirms AAS Will Be New Start Or OH-58 SLEP |archive-url= https://web.archive.org/web/20131023061621/http://www.aviationweek.com/Article.aspx?id=%2Farticle-xml%2Fawx_05_10_2013_p0-577834.xml&p=1 |archive-date= 23 October 2013 |publisher= Aviationweek.com |date= 10 May 2013}}</ref> The Kiowa's scout role was supplemented by tactical [[unmanned aerial vehicles]], the two platforms often acting in conjunction to provide reconnaissance to expose crews to less risk.

In December 2013, the U.S. Army had 338 Kiowas in its active-duty force and 30 in the [[Army National Guard]]. The Army considered retiring the Kiowa as part of a wider restructuring to cut costs and reduce the variety of helicopters operated. The [[Analysis of Alternatives]] for the AAS program found that operating the Kiowa alongside [[RQ-7 Shadow]] UAVs was the most affordable and capable solution, while the [[AH-64 Apache|AH-64E Apache Guardian]] was the most capable immediate solution. One proposal was to transfer all Army National Guard and [[United States Army Reserve|Army Reserve]] AH-64s to the active Army for use as scouts to divest the OH-58. The Apache costs 50 percent more than the Kiowa to operate and maintain; studies note that had it been used in place of the Kiowa in Iraq and Afghanistan, total operating costs would have risen by $4 billion, but also saved $1 billion per year in operating and sustainment costs. [[UH-60 Black Hawk]]s would transfer from the active Army to reserve and Guard units. The aim was to retire older helicopters and retain those with the best capabilities to save money.<ref>{{cite web |url= http://www.marinecorpstimes.com/article/20131209/NEWS04/312090006/ |title= Army Plans To Scrap Kiowa Helo Fleet |archive-url= https://web.archive.org/web/20131214181334/http://www.marinecorpstimes.com/article/20131209/NEWS04/312090006/ |archive-date= 14 December 2013 |publisher= MarineCorpstimes.com |date= 9 December 2013}}</ref> Retiring the Kiowa would fund Apache upgrades.<ref>{{cite web |url= http://www.army.mil/article/118247/Army_aviation_flying_smarter_into_fiscal_squeeze/ |title= Army aviation flying smarter into fiscal squeeze |archive-url= https://web.archive.org/web/20140124212952/http://www.army.mil/article/118247/Army_aviation_flying_smarter_into_fiscal_squeeze/ |archive-date= 24 January 2014 |publisher= Army.mil |date= 14 January 2014}}</ref>

The Army placed 26 out of 335 OH-58Ds in non-flyable storage during 2014. In anticipation of divestment, the Army looked to see if other military branches, government agencies, and foreign customers had interest in buying the type.

[[File:Oh58-004.jpg|thumb|right|An OH-58 Kiowa]]

The ''OH-58A Kiowa'' is a four-place observation helicopter. It has two-place pilot seating, although the controls in the left seat are designed to be removed to carry a passenger up front. During its Vietnam development, it was fitted with the [[Minigun|M134 Minigun]], a 7.62&nbsp;mm electrically operated machine gun.

The [[Australian Army]] leased eight OH-58As in 1971 in Vietnam for eight months.<ref name="161rf">{{cite web |title= History of Bell OH58-A Kiowa Helicopter |url= http://www.161recceflt.org.au/UnitAircraft/Kiowa/history_of_bell_oh58.htm |website= 161 Possums formerly 161 Recce Association |access-date= 8 August 2016 |url-status= dead |archive-url= https://web.archive.org/web/20010302151730/http://www.161recceflt.org.au/UnitAircraft/Kiowa/history_of_bell_oh58.htm |archive-date= 2 March 2001}}</ref><ref name="ADF">{{cite web |title= Army A17 & RAN N17 Bell 206B-1/OH-58A & CAC CA-32 Kiowa |url= http://www.adf-serials.com.au/3a17.htm |website= Australian & New Zealand Military Aircraft Serials & History |access-date= 8 August 2016 |archive-url= https://web.archive.org/web/20160819231724/http://www.adf-serials.com.au/3a17.htm |archive-date= 19 August 2016 |url-status= dead}}</ref> The Australian Government procured the OH-58A for the Australian Army and [[Royal Australian Navy]] as the ''CAC CA-32''.<ref name="ADF" /><ref name="RAAF" /> Licensed produced in Australia by [[Commonwealth Aircraft Corporation]], the CA-32 was the equivalent of the 206B-1 (uprated engine and longer rotor blades).

[[File:Ntsp-oh58-N170FR-070205-01cr.jpg|thumb|left|OH-58C of the [[National Test Pilot School]]. Note the flat windscreen and IR exhaust suppressors.]]

Equipped with a more robust engine, the ''OH-58C'' was supposed to solve issues regarding the Kiowa's power. In addition to the improved engine, it had unique IR suppression systems mounted on its exhaust. Early OH-58Cs had flat-panel windscreens as an attempt to reduce glint from the sun, which could reveal its location to enemies. The windscreens had a negative effect of limiting the crew's forward view, a previous strength of the original design.

The aircraft was also equipped with a larger instrument panel, roughly one–third bigger than the OH-58A panel, which held larger flight instruments. The panel was also equipped with [[Night vision device|Night Vision Goggle]] (NVG) compatible cockpit lighting.<ref name="58C cockpit">{{cite web |url= http://www.flightresearch.com/html/aircraft/oh58.shtml |title= Bell OH-58C Kiowa |publisher= Flight Research, Inc. |url-status= dead |archive-url= https://web.archive.org/web/20060522201749/http://www.flightresearch.com/html/aircraft/oh58.shtml |archive-date= 22 May 2006}}</ref> The OH-58C were also the first U.S. Army scout helicopter to be equipped with the AN/APR-39 radar detector, which alerted the crew to active anti-aircraft radar systems nearby.<ref name="cmh-1977">{{cite web |url= http://www.army.mil/CMH/books/DAHSUM/1977/ch10.htm |title= Department of the Army Historical Summary, 1977 |publisher= United States Army Center of Military History |url-status= dead |archive-url= https://web.archive.org/web/20040901065955/http://www.army.mil/cmh/books/DAHSUM/1977/ch10.htm |archive-date= 1 September 2004}}</ref> Some OH-58Cs were armed with two [[AIM-92 Stinger]]s and are sometimes referred to as OH-58C/S, the "S" referring to the Stinger addition.<ref name="amcom-storm">{{cite web |url= http://www.redstone.army.mil/history/netstorm/chapter3.html |title= Team Redstone's Role in Operation DESERT SHIELD/DESERT STORM |publisher= Redstone Arsenal |url-status= dead |archive-url= https://web.archive.org/web/19970429103523/http://www.redstone.army.mil/history/netstorm/chapter3.html |archive-date= 29 April 1997}}</ref> Called Air-To-Air Stinger (ATAS), the weapon system was intended to provide an air defense capability.

The ''OH-58D'' (Bell Model 406) was the result of the Army Helicopter Improvement Program (AHIP). An upgraded transmission and engine gave extra power, needed for [[nap-of-the-earth]] flight profiles, and a four-bladed main rotor made it quieter than the two-bladed OH-58C. The OH-58D introduced the distinctive Mast-Mounted Sight (MMS) above the main rotor, and a mixed glass cockpit with traditional instruments as "standby" for emergencies.

The ''Bell 406CS'' "Combat Scout" was based on the OH-58D (sometimes referred to as the ''MH-58D'').

The ''Kiowa Warrior'', sometimes referred to by its acronym ''KW'', is the armed version of the OH-58D.

The OH-58E was one of 13 design candidates in the ''Advanced Scout Helicopter'' of 1980. The study's conclusion was to launch the ''Army Helicopter Improvement Program'' (AHIP) in 1981 centered on the OH-58D instead.<ref>{{Cite web |title=OH-58E |url=https://www.globalsecurity.org/military/systems/aircraft/oh-58e.htm |access-date=2024-03-17 |website=www.globalsecurity.org}}</ref>

===OH-58F===
The ''OH-58F'' is an OH-58D upgrade. The Cockpit and Sensor Upgrade Program (CASUP) adds a nose-mounted targeting and surveillance system alongside the MMS. The AAS-53 Common Sensor Payload has an infrared camera, color Electro-Optical camera, and image intensifier; via weight and drag reductions, flight performance increased by 1–2%.<ref name="vertiflite">{{cite journal |title= Stretching the Scout |last= Colucci |first= Frank |journal= Vertiflite |date= May–June 2013 |volume= 59 |issue= 3 |pages= 42–45}}</ref> Cockpit upgrades include the Control and Display Subsystem version 5, more storage and processing power, three color multi-function displays, and dual-independent advanced moving maps.

[[File:OH-58F.jpg|thumb|OH-58F test aircraft in flight]]
In October 2012, the first OH-58F was finished. Unlike most military projects, the Army designed and built the new variant itself, which lowered development costs. It weighed {{convert|3590|lb|kg|abbr=on}}, {{convert|53|lb|kg|abbr=on}} below the target weight and about {{convert|200|lb|kg|abbr=on}} lighter than the OH-58D. The weight savings are attributed to more efficient wiring and a lighter sensor. The first production aircraft began manufacturing in January 2013 and was handed over to the Army by year end. Low rate production was to start in March 2015, with the first operational squadron being fully equipped by 2016. The Army was to buy 368 OH-58Fs, with older OH-58 variants to be remanufactured.<ref>{{cite web |url= http://www.flightglobal.com/news/articles/ausa-us-army-completes-first-oh-58f-test-aircraft-378059/ |title= US Army completes first OH-58F test aircraft |publisher= Flightglobal.com |date= 25 October 2012 |archive-url= https://web.archive.org/web/20121031141046/http://www.flightglobal.com/news/articles/ausa-us-army-completes-first-oh-58f-test-aircraft-378059/ |archive-date= 31 October 2012}}</ref> Due to battle damage and combat attrition, total OH-58F numbers would be about 321 aircraft.<ref>[https://archive.today/20130415093523/http://www.nationaldefensemagazine.org/archive/2013/April/Pages/GivenBudgetUncertainty,ArmedAerialScoutHoveringinLimbo.aspx Given Budget Uncertainty, Armed Aerial Scout Hovering in Limbo] – Nationaldefensemagazine.com, April 2013</ref> The OH-58F's first flight occurred on 26 April 2013.<ref>[http://www.flightglobal.com/news/articles/us-army-oh-58f-makes-first-flight-385319/ US Army OH-58F makes first flight] {{Webarchive|url=https://web.archive.org/web/20130728175121/http://www.flightglobal.com/news/articles/us-army-oh-58f-makes-first-flight-385319/ |date=28 July 2013}} – Flightglobal.com, 30 April 2013</ref>

The Army chose to retire the Kiowa and end the CASUP upgrades. CASUP and SLEP upgrades were estimated to cost $3 billion and $7 billion respectively. The OH-58D could do 20 percent of armed aerial scout mission requirements, the OH-58F upgrade raised that to 50 percent. Replacing the Kiowa with Apaches and UAVs in scout roles met 80 percent of requirements.<ref name="ndm14jan14">[https://archive.today/20140119180058/http://www.nationaldefensemagazine.org/blog/lists/posts/post.aspx?ID=1374 Army Debates Divestment of Kiowa Warrior; Replacement Program in Doubt] – Nationaldefensemagazine.com, 14 January 2014</ref> In early 2014, Bell received a stop-work order for the Kiowa CASUP program.<ref>[http://www.flightglobal.com/news/articles/bell-receives-stop-work-order-for-kiowa-upgrades-398890/ Bell receives stop work order for Kiowa upgrades] {{Webarchive|url=https://web.archive.org/web/20140506200309/http://www.flightglobal.com/news/articles/bell-receives-stop-work-order-for-kiowa-upgrades-398890/ |date=6 May 2014}} Flightglobal.com, 5 May 2014</ref>

===OH-58F Block II===
[[File:OH-58X.jpg|thumb|right|OH-58X, a modified OH-58D prototype. Note nose, pitch link cover and engine cowl area.]]

On 14 April 2011, Bell performed the successful first flight of the OH-58F Block II variant. It was Bell's entry in the [[Armed Aerial Scout]] (AAS) program.<ref>[http://www.military.com/features/0,15240,229853,00.html Bell Flies OH-58 Block II Candidate for AAS] {{Webarchive|url=https://web.archive.org/web/20121208145108/http://www.military.com/features/0,15240,229853,00.html |date=8 December 2012}} Military.com, 19 April 2011</ref> It built on the improvements of the F-model, adding features such as the [[Honeywell HTS900]] turboshaft engine, the transmission and main rotors of the [[Bell 407]], and the tail and tail rotor of the [[Bell 427]]. Bell started flight demonstrations in October 2012.<ref>[http://www.flightglobal.com/news/articles/ausa-bell-starts-oh-58-block-ii-flight-demo-377946/ Bell starts OH-58 Block II flight demo] {{Webarchive|url=https://web.archive.org/web/20130419111303/http://www.flightglobal.com/news/articles/ausa-bell-starts-oh-58-block-ii-flight-demo-377946/ |date=19 April 2013}} Flightglobal.com, 23 October 2012</ref> Bell hoped for the Army to go with their service life extension models instead of the AAS program. The OH-58F is an "obsolescence upgrade", while the Block II was seen as the performance upgrade. This gave the Army financial flexibility via the option of upgrading the Kiowa to the OH-58F and later continuing to the Block II when there were sufficient funds.<ref>[http://www.nationaldefensemagazine.org/archive/2012/December/Pages/ScoutHelicopterCompetitorstoArmyIt’sTimeforaFlyoff.aspx Scout Helicopter Competitors to Army: It’s Time for a Flyoff] {{webarchive|url=https://archive.today/20130415183548/http://www.nationaldefensemagazine.org/archive/2012/December/Pages/ScoutHelicopterCompetitorstoArmyIt%E2%80%99sTimeforaFlyoff.aspx |date=15 April 2013}} – Nationaldefensemagazine.com, December 2012</ref> In late 2012, the Army recommended that the AAS program proceed.<ref name="aas forward"/><ref name=AW_slep/> The Army ended the AAS program in late 2013.<ref>[http://www.defensenews.com/article/20140114/DEFREG02/301140036/Outgoing-General-US-Army-Must-Continue-Fund-Research-Development Outgoing General: US Army Must Continue To Fund Research and Development] {{Webarchive|url=http://webarchive.loc.gov/all/20140117033719/http%3A//www.defensenews.com/article/20140114/DEFREG02/301140036/Outgoing%2DGeneral%2DUS%2DArmy%2DMust%2DContinue%2DFund%2DResearch%2DDevelopment |date=17 January 2014}} – Defensenews.com, 14 January 2014</ref> In light of sequestration budget cuts in 2013, it was decided that the $16 billion cost to buy new armed scout helicopters was too great.<ref name="ndm14jan14"/>

===Others===
The OH-58X was a modification of the fourth development OH-58D (s/n 69-16322) with partial stealth features and a chin-mounted McDonnell Douglas Electronics Systems turret as a night piloting system; including a Kodak FLIR system with a 30-degree field of view. Avionics systems were consolidated and moved to the nose, making room for a passenger seat in the rear. No aircraft were produced.<ref name="Jackson-1"/>
