Air DefenseSentinel A4Air and missile defense radarLockheed Martin's AN/MPQ-64A4 Sentinel A4 is a U.S. Army trailer-mounted air and missile defense radar. It replaces Sentinel A3 with a digital X-band AESA sensor that detects cruise missiles, UAS, fixed-wing and rotary-wing aircraft, and rocket, artillery, and mortar threats while feeding Army air-defense networks.

Air DefenseAN/APY-9 RadarAirborne early warning radarThe AN/APY-9 is Lockheed Martin's UHF airborne early warning radar for the E-2D Advanced Hawkeye, combining mechanical and electronic scanning to build a 360-degree air and surface picture. Official Navy and company sources describe it as the E-2D's primary sensor, designed to detect small, highly maneuverable targets in littoral and overland environments.

Air DefenseAN/SPY-7 radarSolid-state S-band AESA radar familyAN/SPY-7 is Lockheed Martin's modular, scalable solid-state S-band AESA radar family for Aegis-equipped sea- and land-based missile-defense missions. Designated AN/SPY-7(V)1 in 2019, the family was selected for Japanese, Canadian, and Spanish programs and later expanded into land-based derivative deployments such as LRDR and TPY-6.

Air DefenseLong Range Discrimination RadarLong-range ballistic-missile discrimination radarLong Range Discrimination Radar is a Lockheed Martin-built, solid-state GaN S-band AESA radar at Clear Space Force Station, Alaska. It provides search, track, discrimination, and hit-assessment data for U.S. homeland missile defense, and the Space Force accepted it for operational use in 2025 after initial fielding in 2021.

Air DefenseMORFIUSReusable high-power microwave counter-UAS interceptorMORFIUS is Lockheed Martin's reusable, tube-launched counter-UAS interceptor built around a high-power microwave payload and an ALTIUS-derived airframe. The company says it can launch from fixed or mobile platforms, including ground vehicles, aircraft, and vessels, while DoD reporting says it was evaluated at Yuma Proving Ground against small drones.

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.
