The Southjet S-T-1 is a dual seat training aircraft designed by Southjet in 1943, designed to train heavy attack pilots. It was the primary trainer in the Krakabloa air force until 1965 when it was phased out due to the need for new jet trainers. It is fitted with machine guns for strafing and special 250kg training bombs with a small amount of explosives but still having the same trajectory as the normal 250kg bomb. Alternatively, during the Bandit-Wright war, it was converted to an attack plane by increasing engine power and payload. After it had served its military life, if was usually stripped of its weapon capabilities and sold for civilian and recreational use. AG-1 for cockpit.
