Mohawk Details

The Mohawk was developed by Grumman Aircraft as a photo observation and electronic reconnaissance airplane for the US Marines and the US Army. Due to budgetary constraints, the Marines bowed out early in the development cycle. The first Mohawk (YAO-1) prototype flew on April 14, 1959, and entered production in October 1959. It served the US Army standing watch in Europe, Korea, the Vietnam War, Central and South America, Alaska, and during Desert Shield/Desert Storm in the Middle East. The US Army retired it from service in September 1996. A total of 380 original OV-1 Mohawks were produced. All types were built between 1957 and 1969.

Four basic models of the OV-1 were produced, not counting the prototype or pre-production OF-1, YAO-1, and AO-1:

OV-1A This model was used for photo observation and reconnaissance and employed a forward-looking panoramic camera; 64 were built.
OV-1B This model was used to conduct electronic reconnaissance with a SLAR (side looking airborne radar) pod mounted under the fuselage; 101 were built.
OV-1C This model provided electronic reconnaissance by using an IR (infrared) imaging system; 133 were built.
OV-1D This model provided photo observation and gathered electronic intelligence with SLAR and IR; 37 examples were built.

Following are variations or conversions of the original production models:

JOV-1A This model featured XM-14 .50 calibre gun pods and 7- or 19-round 2.75 inch rocket pods; 27 of these were adapted from OV-1As.

JOV-1C These gunships were the same as the JOV-1A but began as an adapted short wing OV-1C with the IR gear removed.

OV-1 "Super C" These had an "A" fuselage, "B" wings, T53-L15A engines, nose and belly cameras, and IR gear. All "Super Cs" except the American Wings Air Museum's S/N 68-15936 which is pictured in flight on the front page and those lost in accidents or in Vietnam were later converted to "D" models.

OV-1 SEAMORE There were only a few Hawks converted in the SEAMORE project.

RV-1D The ELINT (ELectronic INTelligence) version of the OV-1D had all cameras, SLAR and IR gear removed and newer electronic surveillance equipment installed. OV-1Bs were later converted to "D" models and RV-1Ds.

OV-1E This model was an OV-1D with a "glass" cockpit. It was to be the next generation of Hawk with GPS (global positioning system) integrated flight system, 704 engines at 1800 SHP (shaft horsepower), new SLAR package, updated avionics, storm scope, with a corresponding gross weight increase. Two or three prototypes were flown. (Sperry Honeywell donated an OV-1E cockpit to the American Wings Air Museum.)

There were several one-of-a-kind Mohawks used in special applications by numerous agencies.... included the following: US Customs, US Geological Survey, US Navy Test Pilot School, NASA, US Army EPG, Israel Air Force, and others.
