As per the Pentagon, the contract is anticipated to be completed by February 28, 2027. Lithuania is procuring AN/TPS-77 radars from the United States through the Foreign Military Sales (FMS) program. However, Washington is partially financing this acquisition, allocating over USD 29 million under the Building Partner Capacity program.
The introduction of the new AN/TPS-77 radars will significantly enhance the surveillance and airspace protection capabilities of the Lithuanian Armed Forces. Currently, Lithuanian military relies on AN/FPS-117 stationary radars.
The mobile AN/TPS-77 MRR radars operate in the D band and are capable of detecting and tracking flying objects at distances of approximately 450 km from the radar station, flying at altitudes of up to 30,500 meters. The use of gallium nitride (GaN) technology in their construction effectively reduces energy consumption and enhances the overall system’s reliability.
