The former became the Tactical Fighter Experimental, or TFX, which emerged as the F-111, while the second was filled by a version of the U. It was also expensive to buy and operate, with a flyaway cost of million in FY1965, and operational costs over 0 per hour.
After a broad review of its tactical force structure, the U. Air Force decided to adopt a low-cost aircraft to supplement the F-4 and F-111.
Sprey's discussions with Skyraider pilots operating in Vietnam and analysis of aircraft used in the role indicated the ideal aircraft should have long loiter time, low-speed maneuverability, massive cannon firepower, and extreme survivability; In May 1970, the USAF issued a modified, more detailed request for proposals (RFP) for the aircraft.
The threat of Soviet armored forces and all-weather attack operations had become more serious.
While a capable aircraft for its era, with a relatively large payload and long loiter times, the propeller-driven design was also relatively slow and vulnerable to ground fire. On 7 June 1961, Secretary of Defense Mc Namara ordered the air force to develop two tactical aircraft, one for the long-range strike and interdictor role, and the other focusing on the fighter-bomber mission. While the Phantom would go on to be one of the most successful fighter designs of the 1960s, and proved to be a capable fighter-bomber, its lack of loiter time was a major problem, and to a lesser extent, its poor low-speed performance.The two-seat trainer version was ordered by the Air Force in 1981, but funding was canceled by U. Production continued and reached a peak rate of 13 aircraft per month.By 1984, 715 airplanes, including two prototypes and six development aircraft, had been delivered.Its secondary mission is to provide forward air controller – airborne (FAC-A) support, by directing other aircraft in attacks on ground targets.
Aircraft used primarily in this role are designated OA-10.
Its airframe was designed for durability, with measures such as 1,200 pounds (540 kg) of titanium armor to protect the cockpit and aircraft systems, enabling it to absorb a significant amount of damage and continue flying.
