The SPA (Self-Propelled Artillery) advanced artillery system is being developed by Sweden's Bofors Defence and France's GIAT Industries. It is the FH 77B follow-on and eventually its replacement. The SPA artillery system will be capable of provide both close fire support and long range precision strike. The new artillery system will be highly mobile and stealth for improved survivability. In addition the use of advanced shells and modular charges will be the key for outstanding and unprecedented firepower.

According to Bofors Defence sources, the SPA will achieve rates of fire of 16 to 20 rounds per minute, while retaining and increasing FH 77B's multiple round simultaneous impact capability to 10 in just one second. Modular charges will mean a variable muzzle velocity from 450 m/s to more than 1,000 m/s.

Firing standard 155mm ammunition the SPA artillery system will be able to destroy targets at 50 km, while employing special ammunition the maximum range would be up to 100 km.
