Kinetic Weapon Calculator

Enter an appropriate Projectile mass, velocity, and radius. For power plant requirements, indicate the burst duration, and rate of fire. Enter the realtive velocity of a target for targets not at a relative velocity of zero. Fill in the Armor parameters, then simulate the kinetic fire. Note: You can alter the ranges as well, then re-run the simulation.

Note: Whipple shields effectively stop penetration into the hull by kinetic projectile weapons. Additionally, any compartment of the ship will act as an effective whipple shield, thus preventing penetration into further compartments.
