Lithuania Air Surveillance Gains Mobile Layer as US-Made TPS-77 Radars Feed NATO

Lithuania is introducing three Lockheed Martin AN/TPS-77 Multi-Role Radar systems to reinforce its national air-surveillance network and contribute tracking data to NATO's integrated air-defense picture. The mobile radars use electronically scanned surveillance technology on deployable platforms, providing a relocatable complement to fixed sites and supporting airspace monitoring within the Baltic region. The US Foreign Military Sales arrangement was initiated in 2023, with subsequent purchases addressing spare parts and support equipment. Deliveries are expected to be completed by February 2027, after which integration with Lithuanian command-and-control systems and the Baltic Air Surveillance Network will determine their operational employment.
