Развитие морского оружия [2]

Lockheed Martin is basing its LRASM-A design on their stealthy, subsonic, turbofan-powered AGM-158B JASSM-ER(Joint Air-to-Surface Standoff Missile – Extended Range) cruise missile, which doubles the AGM-158 JASSM’s range to over 500 miles. The JASSM program has had more than its share of performance problems, but tests in 2010 saved the AGM-158 JASSM for continued production. The JASSM-ER is still in development, however, and not expected to deploy before 2013. JASSM is an air-launched weapon, but LRASM-A’s characteristics will make it a close counterpart to JASSM’s top rival, MBDA’s Storm Shadow/ Scalp Naval.

 

LRASM-B is envisioned as a ramjet-powered supersonic ship-launched missile, similar to earlier conceptions of hypersonic programs like the now-defunct RATTLRS. It’s intended to leverage prior ramjet development activities, and one of its challenges will be a suite of supporting sensors and avionics that can operate effectively at high Mach ramjet speeds.

 

During Phase 1 of the development program, preliminary designs of the LRASM-A and the LRASM-B variants were successfully completed by Lockheed Martin Missiles and Fire Control. DARPA determined that it provided sufficient confidence in the 2 designs to support further investment for flight testing.

Phase 2 of the development program will continue the development of both missiles and culminate in flight demonstrations of tactically relevant prototypes of both missiles, including a common sensor system from BAE Systems. A series of tests will cover key subsystems, including propulsion, sensors, and mission execution software. Detailed designs, analytical assessments and developmental test results will culminate in critical design reviews (CDR), ensuring that each design is ready to continue on to flight demonstration. LRASM-A will execute 2 air-launched demonstrations, while LRASM-B will complete 4 shipboard Vertical Launch System (VLS) demonstrations.

 

LRASM Missiles: Reaching for a Long-Range Punch
