The LAV-AD replaced the LAV-25's turret with a General Electric Blazer turret featuring two quadruple launchers for Stinger antiaircraft missiles--one launcher situated on the turret's right side and one on top of the turret--and a six-barrel rotary cannon mounted centrally between the commander's and gunner's stations. The gun used Bushmaster type ammunition and had a maximum rate of fire of 1,800 rounds/minute and maximum effective range of 2,500m (1.6 miles). The infrared-homing Stinger missile had a maximum range of 8km (5 miles), a maximum speed of Mach 2.2, and was topped by a 3kg (7lb) high-explosive warhead. The Block I FIM-92E was upgraded with a new processor and roll frequency sensor. The turret crew were housed in separate stations bifurcated by the cannon and one of the missile launchers, with large windows to the front and sides of each position, and either man could control the turret. An automatic digital fire control system allowed the preprogramming of 44 engagement firing sequences, and the stabilization system permitted the vehicle to fire on the move. The turret weighed 2,676kg (5,899lb).
