In its standard configuration, the aircraft utilizes
conventional landing gear (two main wheels and a tail wheel). However, a number of aircraft have been converted to the
Fire Boss aerial firefighting configuration, which utilizes
Wipaire 10000
amphibious floats, so that it can land on a traditional
runway or on water. The Fire Boss can scoop water from a lake or river for use on a fire. In addition to the standard
fuselage-mounted retardant tank, the Fire Boss can have optional foam tanks in the floats. Operations with floats installed have been shown to produce a shorter and narrower retardant drop pattern than wheeled AT-802s.
Armed version In response to the
United States Air Force's
LAAR program and the growing requirement for light
counter-insurgency aircraft, Air Tractor developed an armed model, the AT-802U, in 2008, with engine and cockpit armor, a bulletproof windscreen,
self-sealing fuel tanks, and structural reinforcements for the carriage of of payload. A reinforced wing spar was certified for 12,000 hours of flight time, and the AT-802U was displayed in 2009 at the Paris Air Show. The AT-802 has also been used in counter-drug operations in the
USSOUTHCOM AOR by the U.S. Department of State as a delivery vehicle for herbicides and defoliants over narcotics production facilities. Ten AT-802i were converted by IOMAX USA into an armed configuration with
Roketsan Cirit 2.75" rockets and guided bombs for the
UAE Air Force. The UAE operated them until November 2015 The Archangel is based on a similar cropduster airframe, that of the
Thrush Model 660, however to create the Archangel the basic Model 660 undergoes a much more extensive rebuild in the course of its militarization. Six of the UAE AT-802i were transferred to the
Jordanian Air Force with a further three being transferred to the
Yemeni Government Forces where they have been used in the
2015 Yemeni Civil War. In January 2017, the US State Department approved a deal for twelve AT-802 aircraft for the
Kenya Defence Forces, although as of June 2017 a contract for the proposed sale had not been signed. On 1 August 2022,
United States Special Operations Command indicated they would purchase up to 75 AT-802U Sky Warden aircraft to support special operations forces in fighting irregular wars. Air Tractor will manufacture the airframes and
L3Harris will then modify them into the Armed Overwatch mission configuration. The planes are intended to perform armed
intelligence, surveillance and reconnaissance (ISR) missions at low cost in permissive environments from austere locations, and will allow SOCOM to remove the aging
U-28A Draco from combat service. The Sky Warden can deploy guided weapons including the
APKWS rocket,
GBU-12 laser-guided bomb, and
Hellfire and
Griffin missiles; it has a six-hour loiter time at a radius. The initial contract is for $170 million, with a ceiling of $3 billion for purchase of the full fleet. The plan is for five squadrons of 15 planes, one deployed at a time, three undergoing maintenance, and one for training. Initial service entry is expected in 2026, with all delivered and full operating capability reached in 2029. The AT-802U was given the military designation
OA-1K. ==Variants==
