SW-404 Spitfire is an Anti-Personnel Multiple Rocket Launcher. It is an experimental weapon not yet in general use, designed for anti-sniper, anti-siege and recon-by-fire applications.
It fires a unique low-power canister shell that, immediately after discharge, ablates to release three self-propelled micro-missile rounds which take off in a formation encompassing an arc of roughly 45 degrees. The canister round for the Spitfire is nine cm long and 6.3 cm in diameter, and the individual micro-missiles are 5 cm long with a diameter of 3 cm. The magazine can hold up to 8 rounds.
This weapon is renamed as AR-7 in-game.
