💥 Caliber Selection: A Ballistic Analysis

Fire 105mm, 155mm and 203mm artillery shells side by side and see how caliber, muzzle velocity and elevation trade off against aerodynamic drag, ballistic coefficient, range and time of flight.

ControlsCaliber buttons (105mm / 155mm / 203mm) switch shell diameter, mass and drag coefficient; elevation-angle slider (10-80 deg) tilts the barrel; muzzle-velocity slider (200-550 m/s) sets the propellant charge; Fire button launches a shell along a numerically integrated drag trajectory, keeping up to 3 shots on screen for comparison; drag to orbit, scroll to zoom.

Fire 105mm, 155mm and 203mm artillery shells side by side and watch how caliber, muzzle velocity and elevation angle trade off against aerodynamic drag. Compare range, time of flight and ballistic coefficient as larger calibers resist drag deceleration better than smaller ones.
