In the late 50s, Arstotzka formed it's own government-funded air program and stopped buying weaponry and vehicles from far countries like Germany and China. A young man named Jorgi Corstava and another named Shikov Ilyich worked together to create passenger and cargo aircraft originally, but within a year military aircraft started to be constructed. The first fighter aircraft used was a prop engined aircraft as jet aircraft were quite expensive at the time and required lots of research and building. The IB-4 was a multi-use aircraft that was used until the early 80s as a warplane and then used as a trainer. The exact number produced is around 520, and over 300 were lost in the 6 year war. These aircraft downed 217 aircraft during the 6 years war and destroyed countless vehicles and went on many other missions. 1 to drop fuel tanks, 2 to activate front lights, 3 to activate scope and VTOL to lower it. 4 to activate flaps and VTOL to lower and raise them.
