Guidance Enhanced Missile TBM (GEM-T) is the latest in-production series of the highly successful Raytheon Patriot missile variants available to both U.S. forces and international customers. GEM-T deliveries to the U.S. Army began in 2006. This capability adds a low-noise oscillator for improved acquisition and tracking performance in clutter. The GEM-T missile provides an upgraded capability to defeat tactical ballistic missile (TBM), aircraft and cruise missile threats in complement to the PAC-3 missile.
A modernized digital fuze design eliminates obsolescence and introduces significant performance improvements against TBM targets. This design also increases sensitivity for improved performance against high-speed TBM targets. The low noise front end (LNFE) of the GEM-T has increased seeker sensitivity, improving acquisition/track performance. The new low noise oscillator design has a modified down-link, which provides an increased signal to interference ratio, improving acquisition/ track performance against small ABT and cruise missile targets in clutter.
The GEM variants were combat proven in Operation Iraqi Freedom. In 2003, the U.S. and coalition Patriot units were deployed throughout the CENTCOM region to protect forces and populations from the threat of ballistic missiles. The improvements developed and fielded since 1991 reflect the enhanced capabilities of Patriot to protect against threats to both static assets and forces in the attack. The Configuration-3 ground equipment, PAC-3 and GEM-T series of missiles are all combat proven.
