Air DefenseTPY-4Ground-based multi-mission air-surveillance radarLockheed Martin's TPY-4 is a U.S. ground-based, multi-mission air-surveillance radar for the 3DELRR program. The fully digital software-defined radar can be fielded in fixed or highly mobile configurations, detects smaller and harder-to-track targets in contested RF environments, and is transportable by C-130, C-17, truck, rail, or helicopter.

Air Defense9K35 Strela-10Tracked short-range surface-to-air missile systemThe 9K35 Strela-10, NATO reporting name SA-13 Gopher, is a Soviet tracked short-range air defense system mounted on an MT-LB chassis. Built to protect maneuver forces from low-flying aircraft, helicopters, cruise missiles, and UAVs, it remains relevant in Ukraine because both sides use mobile air-defense vehicles against the dense reconnaissance-drone threat.

Air DefenseAkashMobile short-range surface-to-air missile systemAkash is an Indian mobile surface-to-air missile system developed for point and area air defense of vulnerable sites and forces. During Operation Sindoor in the 2025 India-Pakistan Conflict, Indian official reporting identified Akash among the indigenous air-defense systems used in the layered network that countered Pakistani drone and missile attacks.

Air DefenseAkash Air Force LauncherMobile launcher system for Akash medium-range surface-to-air missilesThe Akash Air Force Launcher (AAFL) is an Indian mobile launcher platform jointly developed by Tata Advanced Systems and DRDO for the Akash air-defense missile family. Tata describes the self-powered, trailer-mounted launcher as capable of transporting and launching up to three Akash missiles in single or salvo mode, with all-weather day/night operation and four AAFLs making up an Akash firing unit.

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.

Air DefenseDavid's Sling air-defense systemAir and missile defense systemDavid's Sling is Israel's medium- to long-range air and missile defense layer, jointly developed by Rafael and Raytheon. It has been operational since 2017 and was used in the Israel-Hamas War to intercept a Gaza-launched rocket.
