Description

The 30 mm HSS 825 is a 30 mm high performance aircraft autocannon. Developed by Hispano-Suiza in the early 1950's, it features very high rate of fire and velocity, specifically the latter when compared to other equivelants for its time like the 30 mm ADEN and 30 mm DEFA (DEFA 541, 551, 552). The gun has a fire rate of 1000 rounds per minute and an average muzzle velocity of 1050 meters per second.

The design of the 30 mm HSS 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 lenghts, L/53 and L/70. The cartridge used in the gun is a 30 x 136 mm rimless cartridge weighing 590-600 gram complete with projectile. Each projectile weighs ca 215 gram.

The weapon was never formerly adopted by any country due to a variety of problems. During Swedish tests in the early 50's 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 dediced 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.

Vehicles equipped with this weapon

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Available ammunition

Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

Pros:

  • High rate of fire
  • High muzzle velocity

Cons:

  • No AP ammo

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
