 Every HE shell carries 27 grams of explosive, enough to heavily damage any plane with a single hit. The only drawback of this cannon is poor accuracy, much worse than in 20 mm cannons, hitting any small target from more than 800 m away can be a problem.

 The DEFA 551 is a French 30 mm revolver cannon based on the German Mauser MG 213C, an experimental cannon designed for Luftwaffe. Its production started in early '50s and was used on some French made planes like the S.O.4050.
-In War Thunder it has many subversions that are used on other French jet fighters.

 The other cannons with similar characteristics are the Russian NR-30, the British ADEN and other subversions of the DEFA cannon. All of them share similar shell velocity close to ~800 m/s and the damage amount they cause, landing a few hits on the other plane will end up very badly for it.

-Since it can carry only 100 bullets per magazine it can fire for only a few seconds, so it is the best to fire at the target when the chance of hitting it is the highest, so basically when it is flying at low speed and when it cannot perform any high speed high G manoeuvers.

 The other aspect that can make it difficult against the other jets is mediocre shell velocity speed compared to machine guns like the M3 Browning or the FMC T-160 revolver cannon.
 The AP shell penetration is quite high so it also can be used against the ground units, especially those used in air battles and tanks from the top, or the wheeled vehicles ones like the Centauro.
