United States Naval Aviator
Naming conventions 
In the U.S. Navy, most Naval Aviators are "Unrestricted Line Officers" (URL), eligible for command at sea; however, a small number of Limited Duty Officers and Chief Warrant Officers are also trained as Naval Aviators. A small number of URL officers trained as Naval Aviators who hold technical degrees at the undergraduate and/or postgraduate level may also opt to laterally transfer to the Restricted Line (RL) as Aeronautical Engineering Duty Officers (AEDO). AEDOs are frequently test pilot school graduates and retain their flying status, with most of their billets being in the Naval Air Systems Command (NAVAIRSYSCOM). An even smaller number of Naval Aviators are in the U.S. Navy Medical Corps, primarily as Naval Flight Surgeons. These are either former URL officers previously designated as Naval Aviators who later attend medical school and transfer to the Medical Corps, or an even smaller percentage of "dual designator" Naval Flight Surgeons who are selected to be Student Naval Aviators as Medical Corps officers.
The U.S. Marine Corps does not categorize its officers in line and staff corps categories as does the Navy, however all of its Naval Aviators are considered combat officers and are analogous to the Navy's URL officers.
Like the Marine Corps, the U.S. Coast Guard also categorizes all of its officers generally, with its Naval Aviators also being considered "operational" officers in the same manner as its Cutterman officers in the Coast Guard's surface cutter fleet.
Until 1981, the U.S. Navy and U.S. Marine Corps also had a small number of senior enlisted personnel trained as pilots. Such individuals were referred to as Naval Aviation Pilots, colloquially "NAPs" or "APs". The since retired NAPs also continue to have a professional organization known as the Silver Eagles, which remains informally aligned with other Naval Aviation professional organizations such as the Association of Naval Aviation, the Tailhook Association, and the Naval Helicopter pilot Association, among others. The U.S. Navy still has an unknown number of NAVCADS (Naval Aviation Cadets) on active or reserve duty who entered service via the NAVCAD program during the late 1980s and early 1990s. NAVCADS were uncommisioned cadets who required to have a minimum of 60 college credit hours to enter training (rather than the Bachelors Degree normally required for entry into the flight training program) and were accessed only through the now defunct AOCS (Aviation Candidate Officer School). Upon completion of AOCS, NAVCADS would enter into flight training and upon successful completion of training be commissioned as active reserve officers. NAVCADS who failed to successfully complete flight training were contractually obligated to enter fleet service as undesignated enlisted personnel. The Naval Aviation Pilot insignia was identical in design to the Naval Aviator insignia worn by commissioned officers.
Except for an extremely small number of enlisted personnel selected for flight school under LDO/CWO programs, Student Naval Aviators must first obtain an officer commission. To become a Naval Aviator, one must be between the ages of 19 and 27 when entering flight training. Adjustments (waivers) can be made up to 24 months for those with prior service, and up to 48 months for those already in the military at the time of application or for Marine Corps PLC (Platoon Leader's Course) applicants with prior enlisted service.
Naval Officers are commissioned through six sources: The United States Naval Academy in Annapolis, The United States Merchant Marine Academy in Kings Point, Naval Reserve Officer Training Corps (NROTC) at a number of colleges and universities across the country, Navy Officer Candidate School in Newport, RI, Marine Corps Officer Candidates School in Quantico, Virginia or via the Navy's Limited Duty Officer (LDO) or Chief Warrant Officer (CWO) programs. Coast Guard Officers receive their commissions either from the United States Coast Guard Academy or Coast Guard Officer Candidate School, both located in New London, Connecticut. Graduates of these programs are commissioned as Navy Ensigns in the U.S. Navy or U.S. Coast Guard, or as Second Lieutenants in the Marine Corps. Individuals must pass an aeronautical screening and be selected for pilot training prior to being designated as Student Naval Aviators (SNAs).
Student Naval Aviators (SNAs) progress through a significant training syllabus ― typically 18 months to two years for initial "winging" as a Naval Aviator via either the Advanced Strike pipeline for those destined for sea-based fixed-wing aircraft (with a slightly modified pipeline for prospective E-2 Hawkeye pilots), the Maritime pipeline for those en route to multiengine land-based aircraft, and the Rotary Wing pipeline for those who will fly helicopters or tilt rotor aircraft (with a slightly modified pipeline for MV-22 Osprey pilots). The longest of these "pipelines" is the Advanced Strike pipeline, averaging over two years from initial pre-flight training to designation as a Naval Aviator. All pipelines include ground and flight training at numerous locations.
Following designation as a Naval Aviator, all newly designated aviators will report to a designated Navy or Marine Corps Fleet Replacement Squadron (FRS), the Coast Guard Aviation Training Center at Mobile, Alabama, or, for pilots destine to fly Navy C-130, Marine Corps KC-130 or Coast Guard HC-130 aircraft, the U.S. Air Force's 314th Airlift Wing at Little Rock AFB, Arkansas.
Introductory Flight Screening (IFS) 
IFS is the first step to becoming a Naval Aviator. All new flight school students first enroll in a civilian flight school (normally near NAS Pensacola, but also located near Marine Corps Base Quantico and the United States Naval Academy) for 14 (previously 25) hours of flight training in small general aviation aircraft. The student must solo (and previously had to complete at least one cross country flight). The purpose of IFS is to screen all students to see their aptitude for flight in actual aircraft, before sending them through all of flight school. Students who already have a Private Pilot Certificate skip IFS and go straight to Aviation Preflight Indoctrination (API) under the cognizance of Naval Aviation Schools Command at NAS Pensacola, Florida.
Aviation Preflight Indoctrination (API) 
Notable dramatization in media: An Officer and a Gentleman
All SNAs start at the "Cradle of Naval Aviation", NAS Pensacola, Florida. There, SNAs (along with Student Naval Flight Officers) receive classroom instruction in aerodynamics, aircraft engines and systems, meteorology, navigation, and flight rules and regulations. They also receive field instruction in survival tactics, survival swimming, and aviation physiology. API is a 6 week long program for commissioned officers, the first four of which are academic and the final two are survival and physiology training.
Prior to its disestablishment, Aviation Officer Candidate School (AOCS) at NAS Pensacola incorporated the entire API syllabus into the nominally 15 week AOCS curriculum. AOCS students were still in a pre-commissioning status when they completed API requirements.
Primary Flight Training 
Following API graduation, SNAs are assigned to Training Wing Five at NAS Whiting Field, Florida or Training Wing Four at NAS Corpus Christi, Texas where they learn to fly the T-34C Turbo Mentor or Beechcraft T-6 Texan II (JPATS). SNAs are no longer sent to Vance AFB. Primary teaches the SNA the basics of flying, is approximately six months long, and is divided into the following stages:
- Ground School (aircraft systems, local course rules, emergency procedures)
- Contact (take-off/landing, limited maneuvers, spins)
- Basic Instruments (common instrument scans, used during maneuvers)
- Precision Aerobatics (aileron roll, loop, 1/2 Cuban Eight, barrel roll, wingover, Split S, Immelmann, etc.)
- Formation (basic section flight, cruise formation flight)
- Radio Instrument Navigation
- Night Familiarization
- Visual Navigation
Intermediate and Advanced Flight Training 
Upon successful completion of Primary Flight Training, SNAs are selected for one of four Intermediate Flight Training paths: E-6B Mercury, multi-engine propeller / maritime aircraft, helicopters, or Tailhook aircraft. Selection is based upon the needs of the service (USN, USMC, etc.), the SNAs performance, and finally, the SNAs preference.
- Those selected for Tailhook aircraft report to NAS Kingsville, Texas or NAS Meridian, Mississippi. Those slated to specifically fly the E-2 Hawkeye or C-2 Greyhound also report to either NAS Meridian or NAS Kingsville, with additional training to follow in the T-44C Pegasus at NAS Corpus Christi.
- A small number are selected for further training leading to assignment in the E-6B Mercury. These SNAs transfer to Vance AFB, Oklahoma for training in the T-1 Jayhawk, or NAS Corpus Christi to fly the T-44C Pegasus.
- Those selected for multi-engine propeller / maritime training are assigned to NAS Corpus Christi, Texas for training in the T-44A Pegasus or TC-12 Huron.
- Those selected for helicopter training are assigned to NAS Whiting Field, Florida, for training in the TH-57B/C.
- Those selected to fly the MV-22 Osprey (USMC SNAs only) are assigned to NAS Whiting Field for abbreviated advanced helicopter training. Upon completion, the SNAs then report to NAS Corpus Christi for multi-engine propeller / maritime training in the TC-12 Huron prior to winging.
Tailhook syllabus 
Student Naval Aviators selected for Tailhook training are assigned to NAS Kingsville, Texas or NAS Meridian, Mississippi flying the T-45C or T-45A. NAS Meridian uses only the T-45C while NAS Kingsville is nearly completely transitioned to the T-45C. The syllabus incorporates basic instrument flying, formation, night familiarization and airway navigation over approximately 58 graded flights lasting approximately 27 weeks. At the completion of the Tailhook syllabus, approximately 80% of those SNAs are selected for Advanced Strike training, leading ultimately to tactical jets like the F/A-18 or AV-8B (Marine Corps only). The remaining 20% receive further training in the E2/C2 pipeline, ultimately leading to assignment flying either the E-2C or C-2 Greyhound. Marine Corps SNA's automatically continue in the Advanced Strike syllabus and will ultimately fly either the F/A-18, AV-8B, or the EA-6B.
Advanced Strike pipeline 
Advanced Strike students continue with approximately 67 additional graded flights lasting approximately 23 weeks in the T-45A/C. The syllabus covers bombing, Air combat maneuvering (ACM), advanced instruments, low-level navigation, tactical formation flying (TACFORM), and Carrier Qualification (CQ) (see Modern US Navy carrier operations). Graduates of Advanced Strike will fly versions of the F/A-18 Hornet and Super Hornet, EA-6B Prowler, EA-18G Growler and AV-8B Harrier II. In addition to current aircraft, this pipeline will eventually produce pilots for the F-35 Lightning II.
Advanced Strike previously produced pilots for the since-retired F-8 Crusader (to include RF-8 variants), F-4 Phantom II (to include RF-4 variants), F-14 Tomcat, A-3 Skywarrior, A-4 Skyhawk, A-6 Intruder, A-7 Corsair II, RA-5C Vigilante, and the S-3 Viking.
E-2/C-2 pipeline 
E-2/C-2 students go straight to CQ in the T-45 Goshawk with approximately 20 additional graded flights over 8 weeks. Upon successful CQ, E-2/C-2 students go to NAS Corpus Christi to complete multi-crew and multi-engine training (approx. 16 weeks) in the T-44A. Following winging, they will go on to fly the E-2 Hawkeye or C-2 Greyhound.
Rotary-Wing pipeline 
Student pilots selected for helicopter training report to NAS Whiting Field, Florida and complete advanced training in the helicopter training squadrons there as well, flying the TH-57 Sea Ranger. Students learn the unique characteristics and tactics of rotary-wing aviation, to include basic helicopter familiarization, instrument flying, night familiarization (including use of night vision goggles or NVGs), low level flight, helicopter formation flight, and airways navigation.
Once they receive their Wings of Gold, Navy helicopter pilots report to their respective Fleet Replacement Squadron (FRS) for training: NAS North Island, CA for the MH-60R Seahawk (HSM) with HSM-41, SH-60F/HH-60H Seahawk (HS) and MH-60S Knighthawk (HSC) with HSC-3, NS Mayport, FL for the SH-60B Seahawk (HSL) and MH-60R Seahawk (HSM), HSM-40 trains pilots for both aircraft, or NS Norfolk, VA for the MH-53E Sea Dragon (HM) and MH-60S Knighthawk (HSC) with HSC-2.
Marine Corps helicopter pilots report to the FRS at MCAS New River for the CH-53D Sea Stallion and CH-53E Super Stallion, MCB Camp Pendleton for the AH-1W Super Cobra, AH-1Z Viper, UH-1N Twin Huey, UH-1Y Venom and CH-46 Sea Knight, or MCAS New River for the MV-22 Osprey.
Coast Guard helicopter pilots will report to the Coast Guard Aviation Training Center in Mobile, Alabama for further training, or the "T-Course," on the MH-60T Jayhawk and MH-65D Dolphin.
The Navy also trains pilots from several NATO and other allied nations as military and naval helicopter pilots.
Land-Based syllabus 
Maritime pipeline 
Maritime students complete their advanced training at NAS Corpus Christi flying the twin engine T-44A Pegasus or TC-12 Huron. Particular emphasis is placed on single-engine flight in varying conditions. Upon receiving their Wings of Gold, Navy pilots report to the P-3 Orion Fleet Replacement Squadron (FRS) for further training in the P-3 and EP-3. Marine Corps pilots report to the KC-130 FRS, while Coast Guard pilots destined for the HC-130 or HC-144 proceed directly to their assigned Air Station. As budget and time allow, the HC-130 pilots will report to an Air Force C-130 Formal Training Unit (FTU) at Little Rock Air Force Base, Arkansas or Dobbins Air Reserve Base, Georgia. In addition to training all Navy, Marine Corps, and Coast Guard maritime pilots, VT-31 and VT-35 trains United States Air Force student pilots bound for C-130 duty. Coast Guard HU-25 Guardian and HC-144A pilots report to the Coast Guard Aviation Training Center(ATC) in Mobile, Alabama for a transition course after reporting to their assigned Air Station. The Coast Guard is in the process of eliminating the HU-25 transition course.
Similarly, Navy E-6 Mercury TACAMO pilots complete advanced training in the T-44C Pegasus at NAS Corpus Christi, TX or the T-1A Jayhawk, a militarized version of the Beechcraft 400, complete with digital cockpit displays. This training is done at the Air Force’s 32nd Flying Training Squadron at Vance Air Force Base, Oklahoma.
Insignia and winging 
The Naval Aviator Insignia is a warfare qualification of the United States military that is awarded to those aviators of the United States Navy, Marine Corps, and Coast Guard who have qualified as Naval Aviators. The Naval Aviator insignia is identical for all three branches, as are the similar Naval Astronaut and Naval Flight Officer badges. Naval Aviation Pilots were awarded the Naval Aviation Pilot badge which, while considered a separate award, was identical in design to the Naval Aviator badge. The badge was designed by John H. Towers c1917, and consists of a single fouled anchor, surmounted by a shield with 13 stripes, centered on a pair of wings. Between January 1927 and October 1929 the design of Naval Aviation Observer Wings was the same as Naval Aviator Wings except the observer wings were silver. Observer wings after that were of a distinct design.
To qualify for the Naval Aviator insignia, a service member must have completed flight training and be designated a qualified pilot of a military aircraft. Traditionally, Student Naval Aviators are awarded "soft wings" immediately after the completion of their final training flight. These soft wings are typically gold-leaf impressions on leather patches that Velcro to the flight suit. The official Naval Aviator insignia are later awarded at a "winging" ceremony.
Community selection 
Upon completion of flight training, a final selection process takes place in which the Student Naval Aviators are assigned a particular fleet aircraft community (e.g., F/A-18A+/C/D/E/F, EA-18G, EA-6B, AV-8B or F-35B/C for Strike; E-2/C-2 for Carrier AEW; SH-60, HH-60, MH-60, MH-65, AH-1, UH-1, CH-53, MH-53 or MV-22 for Rotary-Wing, P-3, P-8, E-6, EP-3, C-130, KC-130, HC-130, HU-25 or HC-144 for Maritime, etc.). This selection is also based upon the needs of the service and performance. Newly-designated Naval Aviators (no longer referred to as "students") are then assigned to a USN or USMC Fleet Replacement Squadron or other similar training organization under the cognizance of the US Coast Guard or the US Air Force, for training on their specific aircraft type. Currently, approximately up to 1,000 pilots are designated each year, and between 1910 and 1995 more than 153,000 Naval Aviators earned their "wings of gold".
Fleet assignments 
Upon completion of FRS training, Naval Aviators are assigned to a fleet squadron – either ship or land based – in their type aircraft. In addition to flying, Naval Aviators also hold one or many “collateral” duties of increasing responsibility such as Legal Officer, Maintenance Division Officer, Training Officer, Safety Officer, etc. Initial fleet assignments typically last approximately three years.
Shore rotation 
After completing a successful tour in the Fleet, Naval Aviators complete a “shore-duty” tour typically as a flight instructor in the Naval Air Training Command or a Fleet Replacement Squadron, adversary pilot, or staff officer. Some complete further military schooling, such as the Naval Postgraduate School or U.S. Navy Test Pilot School, or are assigned specialized flight duty (e.g., foreign exchange pilot under the Personnel Exchange Program (PEP), test pilot, U.S. Navy Flight Demonstration Squadron (the Blue Angels), presidential support in HMX-1, etc.). Typical Navy and Marine Corps shore rotations are approximately two and a half years long, after which time personnel return to the Fleet for either a flying or a non-flying disassociated sea tour for two years, depending on aircraft background and Fleet requirements. Since 2002, some individuals have been selected for what are now known as Global War on Terrorism Support Assignments (GSA), which are one year in length and are typically to either the U.S. Central Command, U.S. Naval Forces Central Command or U.S. Marine Forces Central Command staffs, or forward deployed location supporting previously supporting the former Operation Iraqi Freedom (OIF), the former Operation New Dawn (OND), or the still-in-effect Operation Enduring Freedom (OEF). In previous decades, Naval Aviators were considered 'Wings Plus Five' in that they incurred a minimum 5-year active duty service obligation. Today, all Naval Aviators are 'Wings Plus Eight', i.e., they incur an 8-year service obligation upon receiving their wings, so very few individuals are entitled to separate from active service off their initial shore duty rotation and, instead, have to accept new orders as described above.
Service commitment 
Because of the costly nature of flight training, Naval Aviators incur a longer minimum active duty service commitment than any other occupation in the Navy or Marine Corps. This service commitment begins on the day the Naval Aviator is winged.[dead link]
Student Naval Aviators incur an eight-year active duty service commitment. As of December 2012 however, Marine Corps SNAs only incur a service obligation of 6 years. This was done to tackle the problem of newly minted Majors leaving the service since they had reached the end of their obligation.[dead link]
Naval Reserve Naval Aviators all come from the active ranks. They fly fleet type aircraft (such as the F/A-18 Hornet, EA-6B Prowler and P-3 Orion) as well as aircraft exclusive to the reserve force. These latter aircraft include the F-5 Tiger II, primarily used for fighter adversary support, and the larger cargo or transport aircraft such as the C-9 Skytrain, C-20D Gulfstream III, C-20G Gulfstream IV, C-35 Citation, C-40 Clipper, and C-130 Hercules. These aircraft are used to transport cargo and personnel, including dignitaries and senior leaders.
Squadron Commanding Officer 
Naval Aviators and Naval Flight Officers who successfully complete a fleet tour as a squadron department head (usually while successfully holding the ground position of either the Squadron Operations Officer, or Squadron Aircraft Maintenance Officer for lengths of a year or more and ranked as the top Lieutenant Commander or Major), are considered in a Navy-wide or Marine Corps-wide (as applicable) Aviation Command Screen Board for Squadron Command. Selectees must also have been selected and approved by the U.S. Congress for promotion to the rank of Commander or Lieutenant Colonel (O-5).
Those few selected participate in a variety of command, leadership, legal and safety schools, and required refresher flight training and (if applicable) carrier re-qualifications. Unlike other branches of the Navy, Squadron Commanding Officers (CO) start out the first half of their tours as the Squadron Executive Officer (XO), then "Fleet up" to the top position during their tenure, at a formal change of command, while Marine Corps Squadron Commanding Officers proceed direct to the CO position, that service's Squadron XOs typically being Majors.
Aviation Squadron Commanding Officers (COs) hold sea and shore squadron positions as a first command tour, and may move on to other commands, staff billets, or may retire from there. Typically this tour occurs in the eighteenth to twenty-second year of career service for the individual, shortly after which they will be considered for promotion to the rank of Captain or Colonel (O-6). A small number will be considered for sequential O-5 aviation command, while most will later be screened for major aviation command as O-6s. The role of CO, as it similarly is for the Naval Service's Surface, Submarine, and Marine Corps non-aviation communities is considered a nexxus position for effective military operations.
Aircraft Carrier Commanding Officer 
US Code Title 10 requires that US aircraft carrier commanding officers be Navy unrestricted line officers designated as either Naval Aviators or Naval Flight Officers. Prior to assuming command these officers first command smaller ships and serve as executive officer of an aircraft carrier and go through an extensive training syllabus in ship handling and nuclear propulsion.
