SAGE-227 F experimental guided rocket were developed. PARS SAGE-227 F (Turkey): Experimental Guided MLRS (GMLRS) developed by TUBITAK-SAGE to replace the M26 rockets. Israeli rockets Israel developed its own rockets to be used in the "Menatetz", an upgraded version of the M270 MLRS. The rockets are developed and manufactured by IMI Systems. Trajectory Corrected Rocket (TCS/RAMAM): In-flight trajectory corrected for enhanced accuracy. Romach: GPS-guided rocket with range, warhead, and accuracy of less than 10 meters. Ra'am Eithan ("Strong Thunder"): an improved version of the TCS/RAMAM (in-flight trajectory corrected for enhanced accuracy) with significantly decreased percentage of duds. Alternative Warhead Program In April 2012, Lockheed Martin received a $79.4 million contract to develop a GMLRS incorporating an Alliant Techsystems-designed alternative warhead to replace DPICM cluster warheads. The AW version is designed as a drop-in replacement with little modification needed to existing rockets. An Engineering and Manufacturing Development (EMD) program was to last 36 months, with the alternative warhead GMLRS expected to enter service in late 2016. The AW warhead is a large airburst fragmentation warhead that explodes over a target area to disperse penetrating projectiles. Considerable damage is caused to a large area while leaving behind only solid metal penetrators and inert rocket fragments from a warhead containing approximately 182,000 preformed tungsten fragments. The unitary GMLRS also has an airburst option, but while it produces a large blast and pieces of shrapnel, the AW round's small pellets cover a larger area. On 22 May 2013, Lockheed and ATK test fired a GMLRS rocket with a new cluster munition warhead developed under the Alternative Warhead Program (AWP), aimed at producing a drop-in replacement for DPICM bomblets in M30 guided rockets. It was fired by an M142 HIMARS and traveled before detonating. The AWP warhead will have equal or greater effect against materiel and personnel targets, while leaving no unexploded ordnance behind. In October 2013, Lockheed conducted the third and final engineering development test flight of the GMLRS alternative warhead. Three rockets were fired from away and destroyed their ground targets. The Alternative Warhead Program then moved to production qualification testing. The fifth and final Production Qualification Test (PQT) for the AW GMLRS was conducted in April 2014, firing four rockets from a HIMARS at targets away. In July 2014, Lockheed successfully completed all Developmental Test/Operational Test (DT/OT) flight tests for the AW GMLRS. They were the first tests conducted with soldiers operating
