MIM-104E Patriot PAC-2 GEM/T

The MIM-104E Patriot PAC-2 GEM/T is a Guidance Enhanced Missile-Tactical interceptor for the Patriot air and missile defense system. It modernizes the PAC-2 blast-fragmentation missile with seeker and fuze improvements for tactical ballistic missile threats, and CSIS identified it as the bulk interceptor used by Royal Saudi Air Defense Forces in Patriot defenses against Houthi missile launches during the Yemen Civil War.

Air Defense2K12 Kub / Kvadrat / SA-6 GainfulTracked medium-range surface-to-air missile systemThe 2K12 Kub, exported as Kvadrat and known to NATO as SA-6 Gainful, is a Soviet tracked medium-range surface-to-air missile system built around 3M9 missiles, 2P25 launch vehicles, and the 1S91 Straight Flush radar. In recent conflict archives it appears as a legacy medium-range air-defense system, including Syrian use during the 2018 missile strikes, Armenian use in Nagorno-Karabakh, and a Houthi SA-6/Kub-family engagement that downed a U.S. MQ-9 over Yemen in 2019.

Air DefenseCrotaleShort-range surface-to-air missile systemCrotale is a French short-range surface-to-air missile family built around radar and electro-optical target tracking. The Crotale NG variant paired the VT-1 missile with an integrated launcher, search radar, tracking radar, and optical sensors, making it useful for point defense of forces and fixed sites against low-altitude air threats. France supplied Crotale NG systems to Ukraine during the Russia-Ukraine War to reinforce layered air defense against Russian missiles, aircraft, helicopters, and drones.
