Long Range Land Attack Projectile

The Long Range Land Attack Projectile (LRLAP) is a developmental program to produce a precision guided 155 mm naval artillery shell for the U.S. Navy. The system is under development by Lockheed Martin Missiles and Fire Control, the prime contractor being BAE Systems. In cooperation with BAE a version of LRLAP has been designed to be used with the 5"/54 naval cannon.

The LRLAP uses a base bleed rocket assistance, and an extended range fin glide trajectory, the warhead effectiveness is comparable to that of the new M795 artillery shell,and it is capable of 6 round MRSI impact in a span of 2 seconds. It uses a blast-frag munition.
