76 mm GT 4 gun
editDevelopment/Description
The 76 mm/62 calibre GT 4 rifled gun was developed by Denel Land Systems as the main armament of the Rooikat 76 armoured car. The first production examples of which were delivered to the South African Armoured Corps in 1989. An estimated 244 of these vehicles had been built. So far there have been no export sales of this vehicle. The gun retains the same chamber volume as the Otobreda 76 mm Compact Naval Gun but fires different ammunition. A larger number of 76 mm rounds can be carried when compared with the 105 mm gun. Mounted on the left side of the gun is a 7.62 mm coaxial machine gun. Two types of ammunition have been developed for use with this gun, HE-T and APFSDS-T with the latter having an effective range of 2,000 m. The 76 mm ammunition of the naval gun can also be fired by replacing the mechanical primer with an electric primer.
