-this is a dumb lore i made,please pay not much attention to it-
the FP1A is a co axial contra rotating prop fighter plane of the 1940s Created by Conder Aerodynamics (CAD) in an attempt to prepare the argentinian army against an inminent attack.

Chile had been invaded by the jappanesse empire,and the argentinian goverment feared they would be next. the main advantages this plane had was its short distance radar wich could track Oponents.

Apart from that,The FP1A "Sparrow" was an inferior aircraft as it was a simple aircraft,its main issue was its low range that made a constant dogfight impossible considering the drop tanks wich were ejected for better handling.
