Shell Ballistics Chart

Pick any ship to chart its main-battery shells: AP penetration, impact velocity, flight time, and impact angle versus range. Trajectories are computed by numerical integration of the World of Warships ballistic model.

Calibrated to in-game Legends. AP penetration uses the canonical community formula (1e-7 × Krupp × mass^0.69 × caliber_m^-1.07 × v^1.38). Verified against in-game spec cards across 7 captured Legendary ships: AP Pen Close at muzzle velocity matches to 0.0% (Castilla 620.9, Brisbane 323.8, Vampire-II 140.1, Jinan 174.9, Halland 216.9, C-Colombo 814.1, Venezia 467.7). AP Pen Far at max firing range matches within ±2% on most ships, ±5% on the edges. Flight time is calibrated to in-game Training Room measurements.
