AN/SPY-7 is Lockheed Martin's modular, scalable solid-state S-band AESA radar family for Aegis-equipped missile-defense missions. Designated AN/SPY-7(V)1 in 2019, it is documented in Japan's ASEV program, Spain's F-110 frigate, and Canada's River-class destroyer, while related land systems such as LRDR and AN/TPY-6 use the same solid-state radar technology lineage.

LRDR at Clear Space Force Station and AN/TPY-6 for Guam share SPY-7/LRDR solid-state radar technology; GAO reported AN/TPY-6 further development was directed to cease in January 2025 while retaining the fielded panel as an experimental asset
Variants

Public sources identify three naval AN/SPY-7 designations tied to Japan, Spain, and Canada; LRDR and AN/TPY-6 are related land systems using the same solid-state radar technology lineage rather than naval SPY-7 variants.

Its baseline mission is to detect, classify, track, and locate mortar, artillery, and rocket launches in 90-degree or 360-degree modes, while software and open-architecture upgrades have extended the same family into counter-UAS, air-surveillance, and wider multimission radar roles.
