Lightweight Exo-Atmospheric Projectile (LEAP)

The Lightweight Exo-atmospheric Projectile (LEAP) is a lightweight miniaturized kinetic kill vehicle designed to destroy incoming ballistic missiles both inside or outside the Earth's atmosphere. The warhead is delivered to the interception point by a system such as the Aegis Ballistic Missile Defense System.

Development began in 1985 by the Strategic Defense Initiative Organization, which pioneered the development of miniaturized kill vehicle technology.
