A-7 Corsair II Walk Around. Replacement for the legendary A-4 Skyhawk, the A-7 was a light attack aircraft based on the F-8 Crusader. It was one of the first combat aircraft to feature a head-up display (HUD), a Doppler inertial navigation system and a turbofan engine. First flying in 1965, the A-7 enjoyed the fastest and most trouble-free development of any American combat since WWII and served in the US Navy, US Air Force, Air National Guard and several foreign nations. In combat over Vietnam the 'Sluf' was second only to the B-52 in amount of ordnance dropped on Hanoi and dropped more bombs per sortie with greater accuracy than any other US attack aircraft. More than 150 color and b/w photos, 12 color profiles, line drawings and color covers; 80 pages.
