The M2 Bradley, or Bradley IFV, is an American infantry fighting vehicle manufactured by BAE Systems Land and Armaments, formerly United Defense as part of the Bradley Fighting Vehicle family.

As with other infantry fighting vehicles, the Bradley is designed to transport infantry with armor protection while providing covering fire to suppress enemy troops and armored vehicles. The M2 can hold a crew of three: a commander, a gunner and a driver; as well as six fully equipped soldiers.

The total cost of the program is $5,664,100,000, and the average unit costs $3,166,000.[2]

The U.S. Army is seeking replacement of the Bradley with the GCV Infantry Fighting Vehicle program.[3]

Design[edit]

The Bradley IFV was developed largely in response to the amphibious Soviet BMP family of infantry fighting vehicles, and to serve as both an APC, and a tank-killer. One specific design requirement was that it should be as fast as the new M1 Abrams main battle tank so that they could maintain formations while moving, something which the older M113 armored personnel carrier could not do, as it had been designed to complement the older M60 Patton.

Armament[edit]

The M2's primary armament is a 25 mm cannon which fires up to 200 rounds per minute and is accurate up to 2500 m depending on the ammunition used. It is also armed with twin BGM-71 TOW wire-guided missiles held in a rectangular compartment on the left side of the turret which are capable of destroying most tanks out to a maximum range of 3750 m. However, the missiles can only be fired while the vehicle is stationary. The Bradley also carries a coaxial 7.62 mm medium machine gun, located to the right of the 25 mm chain gun.

The Bradley is equipped with the M242 25 mm chain gun as its main weapon. The M242 has a single barrel with an integrated dual-feed mechanism and remote feed selection.[4] The gun contains ammunition in two ready boxes of 70 rounds and 230 rounds each for a total of 300 ready rounds and carries 600 rounds in storage. The two ready boxes allow selectable mix of rounds such as the M791 APDS-T (Armor-Piercing Discarding Sabot (with) Tracer), and M792 HEI-T (High Explosive Incendiary (with) Tracer) rounds. The tungsten APDS-T rounds proved highly effective in Desert Storm being capable of knocking out many Iraqi vehicles including several kills on T-55 tanks. There have even been reports of kills against Iraqi T-72 tanks at close range.[citation needed] Subsequent ammunition developments resulted in the M919 APFSDS-T (Armor-Piercing Fin Stabilized Discarding Sabot with Tracer) round, which contains a finned depleted uranium penetrator similar in concept to armor piercing munitions used in modern tanks. The M919 was used in combat during the 2003 invasion phase of Operation Iraqi Freedom (OIF).

It is also armed with a M240C machine gun mounted coaxially to the M242, with 2,200 rounds of 7.62 mm ammunition. For engaging heavier targets (such as when acting in an anti-tank fashion), the Bradley has a TOW missile system on board, which was changed to fire TOW II missiles, onwards from the M2A1 model. M2 infantry Bradleys also have turreted firing ports for a number of M231 Firing Port Weapons or FPWs, providing a button-up firing position to replace the top-side gunners on the old ACAV, though the M231 is rarely employed. Initial variants carried six total, but the side ports were plated over with new armor used on the A2 and A3 variants, leaving only the two rear-facing mounts in the loading ramp.

Countermeasures[edit]

The use of Aluminum armor and the storage of large quantities of ammunition in the vehicle initially raised questions about its combat survivability. Spaced laminate belts and high hardness steel skirts have been added to later versions to improve armor protection, although this increases overall weight to 33 tons. However actual combat operations have not shown the Bradley to be overtly deficient as losses have been few. In friendly fire incidents in Desert Storm, many crew members survived hits that resulted in total losses for lighter USMC LAV-25 vehicles.

All versions are also equipped with two four-barreled smoke grenade launchers on the front of the turret for creating defensive smoke screens, and can also be loaded with chaff and flares.

Chassis[edit]

Bradleys have a welded aluminum unit or monocoque structure to which the armor is attached, mostly on the outside. The suspension is by torsion bars and cranks. Six small rubber rimmed, divided road wheels on each side straddle the location flanges sticking up from the tread. These were originally of aluminum, but were changed to steel as vehicle weight increased. The steel treads sit on flat hard rubber "tires".

Mobility[edit]

The Bradley is highly capable in cross-country open terrain, in accordance with one of the main design objectives of keeping pace with the M1 Abrams main battle tank. Whereas the M113 would float without much preparation, the Bradley was initially designed to float by deploying a flotation curtain around the vehicle. This caused some drownings due to failures during its first trials. Armor upgrades have negated this capability.

History[edit]

Production history[edit]

The M2 was named after World War II General Omar Bradley, The M2 carries a crew of three and a six-man infantry squad.

Since entering service with the U.S. Army in 1981, a total of 4,641 M2s have been produced.

Even after the troubled development history of the Bradley[5] additional problems occurred after production started as described in a book by Air Force Colonel James G. Burton,[6] which was adapted for the 1998 film The Pentagon Wars starring Kelsey Grammer and Cary Elwes. Burton advocated the use of comprehensive live fire tests to be used against fully loaded military vehicles to check for survivability. The Army and Navy agreed and established the Joint Live fire testing program in 1984.[7] When testing the Bradley, however, disagreements occurred between Burton and the Ballistic Research Laboratory(BRL) at Aberdeen Proving Grounds which preferred smaller, more controlled, "building block" tests which could be used to improve the databases used to model vehicle survivability as opposed to full up tests with random shots which reduce the possibility of bias but produced little useful statistical data.[7] In addition Burton insisted upon a series of "overmatch" tests in which weapon systems would be fired at the Bradley that were known to be able to easily penetrate its armor. Burton saw attempts to avoid such tests as dishonest while the BRL saw them as wasteful as they already knew the vehicle would fail.[7] The disagreements became so contentious that Congressional inquiry resulted. As a result of the tests additional improvements to vehicle survivability were added.

Combat history[edit]

During the Gulf War, M2 Bradleys destroyed more Iraqi armored vehicles than the M1 Abrams.[8] Twenty Bradleys were lost — three by enemy fire and 17 due to friendly fire incidents; another 12 were damaged. The gunner of one Bradley was killed when his vehicle was hit by Iraqi fire, possibly from an Iraqi BMP-1, during the Battle of 73 Easting.[9] To remedy some problems that were identified as contributing factors in the friendly fire incidents, infrared identification panels and other marking/identification measures were added to the Bradleys. The Bradley's 25mm gun proved effective even against enemy tanks, taking out T-55s and even Asad Babils (the latter at a short range of 500m).

In the Iraq War, the Bradley proved somewhat vulnerable to Improvised explosive device (IED) and rocket-propelled grenade (RPG) attacks, but casualties were light — the doctrine being to allow the crew to escape at the expense of the vehicle. As of early 2006, total combat losses included 55 Bradleys.[10] By 2007, the Army had stopped using the M2 Bradley in combat, instead favoring more survivable MRAPs.[11]

Replacement[edit]

It is the U.S Army's intention that the Ground Combat Vehicle (GCV) replace the M2 Bradley and M113 with the GCV Infantry Fighting Vehicle by 2018. The M3 Bradley could later be replaced with future variants of the GCV.[12][13] The M2A3 Bradley II, and an M2A3 Bradley variant used in Iraq, were included in the GCV Analysis of Alternatives. Vehicles included the AOA were determined to be inferior to the planned GCV.[14] The Army's FY 2015 budget proposal would discontinue the Ground Combat Vehicle program because budget constraints are making it unaffordable. Funding would be redirected to improve the Bradley in the interim until resources are made available to again attempt a Bradley replacement program.[15]

Variants[edit]

M2[edit]

M2 Bradley configured for swimming, 1983.

The M2 was the basic production model, first fielded in 1981. The M2 can be identified by its standard TOW missile system, steel laminate armor, and 500 horsepower (370 kW) Cummins VT903 engine with HMPT-500 Hydro-mechanical transmission. Basic features also included an integrated sight unit for the M242 25 mm gun, and thermal imaging system. The M2 was amphibious with the use of a "swim barrier" or "flotation screen" and was transportable by C-141 Starlifter and C-5 Galaxy aircraft. All M2 vehicles have been upgraded to improved standards. The M2 armor protects the vehicle through a full 360 degrees against 14.5 mm armor-piercing incendiary(API) ammunition.

The turret was offset to the right to maximize the room in the passenger compartment. Six dismounts were held in the passenger compartment. Vision for the troops was provided through three periscopes placed between the rear ramp and the cargo hatch just behind the turret, as well as two periscopes on each side of the hull above the side firing ports. The passenger compartment also held five TOW or Dragon missile reloads. The side and rear hull armor consisted of two 0.25 in (6.4 mm) steel plates one inch apart and 3.5 in (89 mm) away from the aluminum armor. The hull top, bottom, and front consisted of 5083 aluminum armor, and 0.357 in (9.1 mm) steel armor was added to the front third of the hull bottom to increase mine protection.[16]

M2A1[edit]

Introduced in 1986, the A1 variant included an improved TOW II missile system, a Gas Particulate Filter Units (GPFU) NBC system, and a fire-suppression system. By 1992, the M2A1s had begun being remanufactured to upgraded standards. The GPFU system was only connected to the vehicle commander, driver, and gunner, while the infantry squad had to use their own from MOPP suits. A seventh infantryman was also added just behind the center of the turret.[16]

M2A2[edit]

Introduced in 1988, the A2 received an improved 600 horsepower (447 kW) engine with an HMPT-500-3 Hydromechanical transmission and improved armor (both passive and the ability to mount explosive reactive armor). The new armor protects the Bradley against 30 mm APDS rounds and RPGs (or similar anti-armor weapons). The new armor also eliminated the trim vane that made the Bradley amphibious and covered up the side firing ports. Spaced laminate armor was installed to the hull rear and spaced laminate track skirts protected the lower hull. A semicircular shield was attached to the turret rear to add more stowage space as well as act as spaced armor. Kevlar spall liners were added to critical areas. The troop carrying number was reduced to six, eliminating the periscope position behind the driver. After live firing testing, seating and stowage arrangements were redrawn. These upgrades raised the cumulative gross weight of the vehicle to 67,282 lb (30.037 long tons; 33.641 short tons).[citation needed] The M2A2 was qualified to be transported by the C-17 Globemaster III. M2A2s were all eventually modified to M2A2 ODS or M2A3 standard.[16]

M2A2 ODS/ODS-E[edit]

The "Operation Desert Storm" and "Operation Desert Storm-Engineer" improvements were based on lessons learned during the first Gulf War in 1991. The major improvements included an eye-safe laser rangefinder (ELRF), a tactical navigation system (TACNAV) incorporating the Precision Lightweight GPS Receiver (PLGR) and the Digital Compass Systems (DCS), a missile countermeasure device designed to defeat first-generation wire-guided missiles, and the Force XXI Battle Command Brigade and Below (FBCB2) Battlefield Command Information System. The internal stowage was further improved and a thermal imaging system was added for the driver. The infantry squad was increased again to seven men, six of which sat facing each other on two 3-man benches in the passenger compartment, with the seventh back in the position behind the turret. An MRE ('Meal, Ready-to-Eat') heater was added to the vehicle to assist in the preparation of food while in the field or warzone. The Dragon missile was also replaced with the option of the Javelin anti-tank missile.[16]

M2A3[edit]

Introduced in 2000, the A3 upgrades make the Bradley IFV totally digital and upgraded or improved existing electronics systems throughout improving target acquisition and fire control, navigation, and situational awareness. Also, the survivability of the vehicle is upgraded with a series of armor improvements, again both passive and reactive, as well as improved fire-suppression systems and NBC equipment.[17]

The A3 Bradley incorporates the Improved Bradley Acquisition Subsystem (IBAS) and the Commander’s Independent Viewer (CIV). Both include a second-generation forward looking infrared (FLIR) and an electro-optical/TV imaging system, and the IBAS also has direct-view optics (DVO) and the eye-safe laser rangefinder (ELRF).[18] The CIV allows the commander to scan for targets and maintain situational awareness while remaining under armor and without interfering with the gunner’s acquisition and engagement of targets.[19]

The A3’s fire control software (FCSW) combines laser range, environmental readings, ammunition type, and turret control inputs to automatically elevate the gun for range and to automatically generate a kinematic lead solution if a target is moving.[18] This functionality, very similar to that of the M1A2 Abrams, allows the gunner or commander to center the reticule on a moving target, lase the target, and achieve a first-round-hit, without the need to fire sensing rounds and adjust aim.[19][20] The FCSW incorporates a thermal aided target tracker (ATT) function that can track two targets in the FLIR field of view and switch between them, primarily intended for employing TOW missiles against moving vehicles.[20] The FCSW also allows the turret and gunner’s sights to be slewed automatically onto a target that has been designated with the CIV.[19]

The A3 Bradley uses a position-navigation subsystem that incorporates a global positioning system (GPS), an inertial navigation unit (INU), and a vehicle motion sensor (MVS),[18] which, in addition to allowing accurate own-vehicle navigation, allows accurate position reporting and hand-off of designated targets to other units via FBCB2.[20]

The Commander’s Tactical Display (CTD) presents information from FBCB2 and the vehicle navigation systems on a moving-map display, allows the commander to communicate via text over FBCB2, and allows him to check vehicle built-in test (BIT) information and access various other information.[20] The Squad Leader’s Display (SLD) in the infantry compartment improves the situational awareness of the passengers by allowing them to view navigational information from FBCB2 and imagery from the IBAS, CIV, or Driver's Vision Enhancer (DVE) to familiarize themselves with their surroundings prior to dismounting.[18]

The M2A3 Bradley II, and an M2A3 Bradley variant used in Iraq, were included in the GCV Analysis of Alternatives.[14]

Other uses of the Bradley chassis[edit]

The Bradley series has been widely modified. Its chassis is the basis for the M270 Multiple Launch Rocket System, the M4 C2V battlefield command post, and the M6 Bradley Linebacker air defense vehicle. Armed with a quad Stinger surface to air missile launcher in place of the TOW anti-tank missiles and maintaining the 25 mm autocannon, the M6 Bradley Linebacker Air Defense Vehicle (no longer in service) possessed a unique role in the U.S. Army, providing highly mobile air defense at the front line. Its suspension system has also been used on upgraded versions of the U.S. Marines' Assault Amphibious Vehicle.
