Press the Sprite/Press Space An SPA (Self Propelled Altillery) design I made. it was meant to used for attacking aircraft, it's equipped with time fuse high explosive shell and high explosive shells. But it was also equipped with high penetration shell (HEAT-FS, with over 500mm of penetration) because it was also meant to be used as an Altillery)
Inspired by 12.8cm Flak 40
