The Navy successfully completed its latest round of long-range, land-attack projectile (LRLAP) guided-flight tests, Aug. 3, at White Sands Missile Range, N.M.
LRLAP is a 155mm rocket-assisted guided projectile designed to support land-attack operations in conjunction with the Advanced Gun System (AGS) on DDG 1000 Zumwalt class destroyers. The four flight tests flew accurately to a designated impact point and met test objectives for successful gun launch, rocket motor ignition and operation, GPS acquisition, and terminal guidance.
"This test marks a significant progress in development of the tactical LRLAP hardware, including a first-time demonstration of LRLAP's point detonation warhead fusing mode, one of the last remaining capabilities to be proven in a flight test environment," said Capt. Timothy Batzler, Navy Surface Ship Weapons major program manager, Program Executive Office for Integrated Warfare Systems. "We also successfully demonstrated our tactical solution to propulsion challenges that have been a key program focus for the last few years. These are important steps in maturation of the LRLAP design as we approach shipboard testing in FY (Fiscal Year) 15."
The munition employs a GPS-based guidance system, unitary warhead with a selectable height-of-burst or point-detonation fuze, and is launched using a unique propelling charge developed specifically for this application The AGS system will be capable of firing LRLAP rounds in excess of 10 rounds per minute from each of the DDG 1000's two gun mounts.
"These LRLAP tests are instrumental in demonstrating the robust land-attack capability on DDG 1000 destroyers," said Capt. James Downey, DDG 1000 program manager in Program Executive Officer Ships.
A series of LRLAP guided flight tests will be executed in the next 14 months to demonstrate LRLAP's performance and reliability in various conditions prior to initial production. Currently, the program is scheduled to proceed with low rate initial production and ship integration during FY 2014, prior to initial operational capability in FY 2016.
