MIM-104E Patriot PAC-2 GEM/T

Also known as
  • MIM-104E
  • PAC-2 GEM-T
  • PAC-2 GEM/T
  • GEM-T
  • Patriot GEM-T
  • Guidance Enhanced Missile-Tactical

The MIM-104E Patriot PAC-2 GEM/T is the Guidance Enhanced Missile-Tactical interceptor in the Patriot PAC-2 family. It keeps the larger PAC-2 blast-fragmentation form factor while adding seeker and fuze improvements for tactical ballistic missile threats, and open sources tie GEM-T to Operation Iraqi Freedom, Saudi Patriot defenses in Yemen, and Ukrainian Patriot batteries in the 2014 Russia-Ukraine War.

Role in Conflicts

Combat And Supply Context

The GEM-T record is best read as an interceptor-specific layer inside Patriot service history: the same missile family appears in direct combat reporting, Saudi missile-defense operations, and Ukraine-driven replenishment pressure.

Launch System

PAC-2 GEM/T is an interceptor round for Patriot batteries, not a standalone firing system.

PAC-2 changed the missile package before Desert Storm, became the visible Patriot missile-defense baseline of the 1990 Gulf War, and remained part of coalition Patriot combat use in the 2003 Iraq War before later PAC-2 GEM/GEM-T and PAC-3 interceptors took over the modernized Patriot mix.

Developed from the 1960s SAM-D program, it evolved from aircraft defense into a high-value air and missile defense layer used in Desert Storm, Operation Iraqi Freedom, Yemen, Ukraine, Gulf base defense, and reported 2026 Iran-war drone defense over Bahrain.

PAC-3 CRI gives Patriot launchers a dense 16-round loadout, while PAC-3 MSE uses a larger dual-pulse motor and control changes for greater defended battlespace; documented combat and transfer contexts include Iraq in 2003, Yemen, Ukraine, and U.S.-Qatari Patriot defense during the June 2025 Iran missile attack on Al Udeid.

The missile is integrated with fighters including Eurofighter/Typhoon, Gripen, F-16, Tornado, EF-18, KF-21, and F-5E; Reuters reporting also documents Saudi Eurofighters using IRIS-T against drones fired from Houthi-controlled Yemen. Diehl describes the same air-to-air missile hardware as the effector in the short-range IRIS-T SLS ground-based air-defense system.

Its compact TELAR layout made it exportable and self-contained compared with earlier Soviet coastal batteries; in the 2014 Yemen Civil War, Houthi forces acquired Rubezh/P-15 stocks from Yemeni military inventories and continued to display the type as part of their anti-shipping arsenal.
