The 155mm Long Range Land Attack Projectile (LRLAP), is the primary projectile of the Advanced Gun System (AGS), the main armament of the U.S. Navy’s next-generation DDG 1000 Zumwalt-class destroyer. It provides long-range off-shore precision fire support to Marine Corps and Army forces engaged in expeditionary assaults or littoral urban operations.
The 155mm LRLAP is both the most accurate and longest-range guided projectile in U.S. Navy history, with a maximum range in excess of 63 nautical miles. It’s precision and near vertical angle of fall enables the Warfighter to defeat targets in the urban canyons of coastal cities with minimal collateral damage.
The LRLAP system provides high-volume fire support at a rate of 10 rounds per minute through the depth of the magazine. It uses the world’s most advanced, g-hardened electronics—including a global positioning system and inertial measurement unit—to withstand the punishing gun-launch environment.
155mm LRLAP provides single strike lethality against a wide range of targets, with three times the lethality of traditional 5-inch naval ballistic rounds—and because it is guided, fewer rounds can produce similar or more lethal effects at less cost. LRLAP has the capability to guide multiple rounds launched from the same gun to strike single or multiple targets simultaneously, maximizing lethal effects.
