Скачать или смотреть Hispano‑Suiza HS 404 20mm — WWII Aircraft Cannon

The Hispano‑Suiza HS.404 is one of the most famous 20mm aircraft cannons of World War II, valued for giving fighter aircraft a hard‑hitting punch beyond rifle‑calibre guns.

Why it mattered
As air combat evolved, pilots needed fewer hits with more effect—20mm cannon shells could do the damage that bursts of smaller rounds often couldn’t, especially against tougher targets.

Where you’d see it
The HS.404 is strongly associated with WWII fighter armament, appearing in multiple air forces and on well‑known fighter types (your exact on-screen country/year should match the reference image you’re using).

Light technical context (kept short)
Caliber: 20mm, meaning high per‑hit effect compared to machine guns.

Role: fighter offense (and sometimes interception) where short, accurate bursts mattered.

Next request (so I match your exact image)
If you tell me the country + year you want to lock (UK / France / USA / USSR) and which aircraft your reference image comes from (if any), I’ll tailor the title/description wording to avoid over-claiming.

Pinned comment
HS.404 (20mm) — a legendary WWII aircraft cannon: fewer rounds, bigger effect, built for fighters that had to end the fight fast.
Which one should I do next: MG 151/20, MK 108 (30mm), or ShVAK (20mm)?
