Japan's 76 mm railgun is presented as an air-defence and deterrent weapon against aerial attack. That calibre is large enough for an adaptable projectile while remaining small enough for production in volume. Its power requirement is expected to be lower than that of larger railgun concepts intended for land attack. Incorporating railguns and laser systems into current and future ships remains a development prospect in this discussion.

Why Japan's railgun concept uses a 76 mm projectile
The 76 mm calibre supports an air-defence concept with adaptable ammunition, volume production, and lower power demands than larger land-attack railguns.
