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 Systems a version of LRLAP has been designed to be used with the 127 mm (5-inch)/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 fragmentation type warhead.

In November 2016, the Navy revealed it had decided to cancel procurement of the LRLAP. This was due to rising costs resulting from the trimming of the Zumwalt-class destroyer fleet to just three ships, raising individual shell cost to $800,000-$1 million, about as much as the Tomahawk cruise missile. About 90 rounds had been secured for testing aboard the three hulls, but a full buy of about 2,000 planned rounds would be about $1.8-$2 billion.
