Hispano HS 825 (30 mm)
The 30 mm HS 825 is a 30 mm high performance aircraft autocannon. Developed by Hispano-Suiza in the early 1950s, it features very high rate of fire and muzzle velocity, particularly the latter when compared to other equivalents of its time like the 30 mm ADEN and 30 mm DEFA (541, 551, and 552). The gun has a fire rate of 1,000 rounds per minute and an average muzzle velocity of 1,050 m/s.
The design of the 30 mm HS 825 is based on an enlarged 20 mm Hispano-Suiza HS 404 but with a dedicated belt feeding mechanism. The weapon was produced in two barrel lengths, L/53 and L/70. The cartridge used in the gun is a 30 x 136 mm rimless cartridge weighing 590-600 g complete with projectile. Each projectile weighs approximately 215 g.
The weapon was never formerly adopted by any country due to a variety of problems. During Swedish tests in the early '50s it was found that the gun leaked powder gas from the chamber which after every 10 shots of fully automatic fire got concentrated enough to were it ignited and made sparks. Due to this the Swedish air force decided to adopt the 30 mm ADEN instead, a fate which probably occurred elsewere in the world as well. However the weapon was fitted to a variety of prototype aircraft, such as the Swiss FFA P-16 and the Italian Sagittario 2.
