The '''Grumman OV-1 Mohawk''' is an American armed military observation and attack aircraft that was designed for battlefield surveillance and light strike capabilities. It has a twin [[turboprop]] configuration, and carries two crew members in side-by-side seating. The Mohawk was intended to operate from short, unimproved runways in support of [[United States Army]] maneuver forces.

The Mohawk began as a joint Army-Marine program through the then-Navy [[Bureau of Aeronautics]] (BuAer), for an observation/attack plane that would outperform the [[Cessna O-1 Bird Dog|Cessna L-19 Bird Dog]]. In June 1956, the Army issued Type Specification TS145, which called for the development and procurement of a two-seat, twin turboprop aircraft designed to operate from small, unimproved fields under all weather conditions. It would be faster, with greater firepower, and heavier armour than the Bird Dog, which had proved vulnerable during the [[Korean War]]. The Mohawk's mission would include observation, [[Artillery observer|artillery spotting]], air control, emergency resupply, naval target spotting, liaison, and radiological monitoring. The Navy specified that the aircraft must be capable of operating from small "jeep" [[Escort carrier|escort carriers]]. The DoD selected Grumman Aircraft Corporation's G-134 design as the winner of the competition in 1957. Marine requirements contributed an unusual feature to the design. As originally proposed, the OF-1 could be fitted with water skis that would allow the aircraft to land at sea and taxi to island beaches at {{convert|20|kn|km/h}}. Since the Marines were authorized to operate fixed-wing aircraft in the [[close air support]] (CAS) role, the mockup also featured underwing pylons for rockets, bombs, and other stores.
The Air Force did not like the armament capability of the Mohawk and tried to get it removed, while the Marines did not want the Army's sophisticated sensors. However the Navy then opted to spend the allocated budget on a fleet oil tanker instead, so the Marines had to drop out of the program in September 1957. The Army continued with armed Mohawks and developed cargo pods that could be dropped from underwing hard points to resupply troops in emergencies.
The radar imaging capability of the Mohawk was to prove a significant advance in both peace and war. The [[Side looking airborne radar|Side-Looking Airborne Radar]] (SLAR) could look through foliage and map terrain, presenting the observer with a film image of the earth below only minutes after the area was scanned. In military operations, the image was split in two parts, one showing fixed terrain features, the other spotting moving targets.
The prototype (''YAO-1AF'') first flew on April 14, 1959. The OV-1 entered production in October 1959.
In mid-1961, the first Mohawks to serve with U.S. forces overseas were delivered to the [[United States Army Europe|7th Army]] at [[Coleman Army Airfield|Sandhofen Airfield]] near Mannheim, Germany. Before its formal acceptance, the camera-carrying AO-1AF was flown by Ralph Donnell on a tour of 29 European airfields to display it to the U.S. Army field commanders and potential European customers. In addition to their Vietnam and European service, SLAR-equipped Mohawks began operational missions in 1963 patrolling the [[Korean Demilitarized Zone]]. Germany and France showed early interest in the Mohawk, and Grumman actually signed a license production agreement with the French manufacturer [[Breguet Aviation]] in exchange for American rights to the [[Breguet Atlantic|Atlantic]] maritime patrol aircraft.
The very nature of the joint Army/Marine program had forced design compromises, such as [[ejection seat]]s,<ref>{{Cite web | url=http://www.ejectionsite.com/ov1seats.htm |title = The Ejection Site: OV-1 Mohawk Ejection Seats}}</ref> that made the aircraft expensive and, sometimes, an openly resisted item in Army budgets. Orders for the OV-1 stopped in Fiscal 1964, and the controversy in the Pentagon over the armed Mohawk peaked with a 1965 directive that prohibited the Army from operating armed fixed-wing aircraft (See the [[Johnson-McConnell agreement of 1966]]). Operational success in Vietnam led to additional Mohawk orders in 1966, and by 1968, five surveillance companies were operating in Southeast Asia.
The last of the Mohawk versions to enter production was the OV-1D with more powerful [[Lycoming T53|T53-L-701]] engines, improved avionics, and interchangeable mission pallets that made it possible to switch the aircraft from infrared to SLAR configuration in about an hour. The first four OV-1Ds were prototypes converted from earlier production airframes, and the first flew in 1969. These were followed by 37 new-build aircraft, the last of which was delivered in December 1970.
Over the years, the mission and the aircraft underwent many changes and roughly 380 were built over all variants. Mohawk variants included the JOV-1 [armed reconnaissance], OV-1A, [visual and photographic], OV-1B [visual, photographic, and side-looking radar (SLAR) pod], the OV-1C [visual, photographic, and infrared], and the OV-1D (SLAR pod and bigger wings), OV-1E [enlarged fuselage for more sensor operators or cargo], EV-1E [special [[Signals intelligence#ELINT|electronic intelligence]] installation] and RV-1E [advanced ELINT reconnaissance]. A four-engined Model 134E with [[tiltwing]]s and tail [[ducted fan]] for control for [[VTOL]] was proposed to the Army but not built. Model 134R was a tandem cockpit version offered to meet the [[North American Rockwell OV-10 Bronco#Light Armed Reconnaissance Aircraft|Light Armed Reconnaissance Aircraft]] (LARA) requirement, but the NA300 was chosen instead becoming the [[North American Rockwell OV-10 Bronco|OV-10]].
==Operational history==
{{expand section|date=August 2015}}
=== United States Army ===
The U.S. Army flew the OV-1 operationally in the [[Vietnam War]], with sixty-five lost to accidents and ground fire, and one shot down by a North Vietnamese fighter.<ref>{{cite web|url=http://www.defensemedianetwork.com/stories/the-ov-1-mohawk-remembered-firsthand-piloting-the-mohawk-in-vietnam/|title=The OV-1 Mohawk Remembered Firsthand: Piloting the Mohawk in Vietnam|publisher=Defense Media Network|date=24 September 2013|access-date=15 December 2015}}</ref>
In early 1968, while flying an OV-1 over South Vietnam, U.S. Army Captain Ken Lee shot down a [[MiG-17]] “Fresco” fighter jet with his XM14 .50 in. (12.7&nbsp;mm) caliber gun pods as well as two M159 unguided rocket pods, becoming the only Army Aviator to ever down a MiG. Due to the [[Key West Agreement]], the Army tried to keep the shootdown a secret for fear that it would allow the USAF to transfer Mohawks to its inventory. Lee's kill was finally formally recognized by the Army in 2007.<ref>{{Cite web|last=Wolf|first=Andy|date=April 17, 2020|title=The Army's only air to air kill since WWII was done with a .50 cal in Vietnam|url=https://warisboring.com/the-armys-only-air-to-air-kill-since-wwii-was-done-with-a-50-cal-in-vietnam/|access-date=2020-09-14|website=warisboring.com|language=en-US}}</ref>
The Army also used the aircraft during [[Gulf War|Operation Desert Storm]].
Starting in 1972, the [[Army National Guard]] (ARNG) began to receive the Mohawk, with the ARNG eventually operating thirteen OV-1Bs, twenty-four OV-1Cs, and sixteen OV-1Ds serving with three aviation units in Georgia and Oregon.  The Oregon Army National Guard Unit operating the Mohawk was located at [[McNary Field]] in Oregon, initially as the 1042nd Military Intelligence Company (Aerial Surveillance), then reflagged as the 641st Military Intelligence Battalion (CEWI)(Aerial Exploitation).
U.S. Army OV-1s were retired from Europe in 1992, from South Korea in September 1996, and finally in the United States in 1996, superseded by newer systems, newer aircraft, and the evolution of [[reconnaissance satellite]]s. The OV-1 was primarily replaced by the EO-5C, a militarized version of the [[de Havilland Canada Dash 7]] turboprop airliner equipped with a SLAR system, until the U.S. Air Force's [[Northrop Grumman E-8 Joint STARS]] (Joint Surveillance Target Attack Radar System) aircraft became fully operational.
As of 2011, [[Alliant Techsystems]] partnered with the Broadbay Group and Mohawk Technologies of Florida in a venture to return an armed, modernized version of the OV-1D to operational use as a [[counter-insurgency aircraft]].  A demonstrator was equipped with a [[Forward looking infrared|FLIR]] Star Safire turret and a ventral, trainable [[M230 chain gun]].<ref>{{cite journal |journal=Defense Technology International Magazine |date=April 2011 |volume=5 |issue=4) |page=40 |publisher=McGraw-Hill/DTI |location=Washington, D.C. |issn=1935-6269}}</ref><ref>{{cite news |url=http://defensetech.org/2010/10/28/old-school-coin-planes-keep-coming-back/ |first=John |last=Reed |title=Old School COIN Planes Keep Coming Back |work=Defensetech |date=2010-10-28}}</ref>
=== Argentine Army ===
{{expand section|date=March 2016}}
The [[Argentine Army Aviation]] received twenty-three OV-1s in the 1990s. Ten were operational and the rest were used for spare parts.<ref>{{cite web|url=https://www.dover.af.mil/Air-Show/Aerial-Acts/Mohawk-Airshows-OV-1/|title=Mohawk Airshows: OV-1 Factsheet|publisher=Dover Air Force Base|access-date=10 March 2020}}</ref> They became inactive and retired from use in 2015.
==Accidents and incidents==
On 1 November 2019, a Grumman OV-1D Mohawk operated by Mohawk Airshows crashed at Witham Field, [[Stuart, Florida]], during the Stuart Air Show. The aircraft was destroyed and the pilot was killed. Its serial number was 68-15958.<ref>{{Cite web|title=National Transportation Safety Board Aviation Accident Preliminary Report{{!}}20191102X80415-20200914-90331|url=https://app.ntsb.gov/pdfgenerator/ReportGeneratorFile.ashx?EventID=20191102X80415&AKey=1&RType=HTML&IType=FA|access-date=2020-09-14|website=app.ntsb.gov}}</ref>
On 14 January 1981, a Grumman OV-1D Mohawk crashed and burned in a rural area near [[Lampasas, Texas]] during a maintenance test flight out of [[Fort Hood, Texas]] for engine rigging and nose gear strut replacement. The [[Inertial Navigation System]] had stretched a wire/pulled a pin at a computer connector and the pin re-locked. Pilot CW3 Sandy L. Oliphant and SSG Roger A. Meadows were killed instantly.
