The Air Tractor-L3Harris OA-1K Sky Warden (company designation AT-802U) is an American fixed-wing, single-engine Light Attack/Armed Reconnaissance aircraft built by Air Tractor and L3Harris for the Armed Overwatch program of the United States Special Operations Command (SOCOM). It was developed from the Air Tractor AT-802, an American aircraft often used for agricultural purposes.
The AT-802U Sky Warden won the Armed Overwatch trial, and on 1 August 2022, SOCOM announced a US$3 billion contract to purchase 75 aircraft by 2029.[1]
The AT-802U Sky Warden was developed from the Air Tractor AT-802, for the Special Operations Command's Armed Overwatch trial. A version of the AT-802 has been used for years eradicating coca leaf crops (used in the production of illicit drugs) and as a result was already outfitted with lightweight composite ballistic armored engine compartment and cockpit, called a "bathtub." The windshield features flat ballistic glass panels. The cockpit is built of a steel tube frame design to act as a roll cage, and can support the entire weight of the aircraft.[2]
The aircraft is not designed to fit ejection seats. The fuel lines and fuel tank are self-sealing and features emergency fuel jettison.[2] Restraints include a 5-point harness equipped with airbags. Essential flight controls are present in both the front and rear seats. The landing gear configuration differs from most modern aircraft in that it is a tail-wheel configuration, which is optimal for austere and unimproved airstrip landings.
The AT-802U is designed for expedient deployment and can be disassembled within a day to fit inside a single C-17 cargo aircraft.[3] It can then be reassembled to mission-ready status within a single day.
On 1 August 2022, Air Tractor and L3Harris were awarded a US$3 billion contract for 75 aircraft. The contract included an upfront payment of US$170 million, with the rest being paid out as the fleet is delivered. The aircraft is built in two stages; the airframe is built by Air Tractor in Olney, Texas, and the armor and weapons systems are added by L3Harris in Tulsa, Oklahoma.[4] It is to replace the U-28A Draco, often used for anti-insurgency operations.[5]
The AT-802U was officially designated the OA-1K in late 2022.[6]
On December 15, 2023, the Government Accountability Office (GAO) released a report urging the Pentagon to slow down the program until SOCOM makes a better justification for so many planes. GAO suggested SOCOM needs a “substantially smaller” fleet of Sky Wardens, but did not recommend a number itself.[7]
