Pave Knife
The Ford Aerospace AN/AVQ-10 Pave Knife was an early targeting pod developed by the USAF and US Navy to designate and guide laser-guided bombs.
Pave Knife was developed in 1969 to replace the original, essentially improvised Airborne Laser Designator (ALD) and TRIM pod (see A-6 Intruder). ALD was not a pod but a hand-held laser operated by the weapon systems officer to mark targets for Paveway laser-guided bombs. Pave Knife was a roughly banana-shaped external pod, weighing about 550 kg (1,200 lb), containing a steerable laser and closed-circuit television camera. The Weapon Systems Officer or bombardier/navigator (BN) monitored the TV image with a small Sony TV in the cockpit and steered the laser onto the target with a hand controller, then passing the target information to the aircraft's gun sight.
When Pave Knife was sent out for bid by the Air Force, it was for a firm fixed-price type of contract, it involved design, development, and manufacture of one prototype, and also a quick reaction project. Quick reaction meant it was considered of a vital nature for the Vietnam War effort. This meant it was a high risk project for the successful bidder.
