Latvia has received the first of three TPS-77 Multi-Role Radar (MRR) air systems from Lockheed Martin. 

The company recently completed a successful site acceptance test of a TPS-77 Multi-Role Radar (TPS-77 MRR) marking an on-time delivery of the first of three radars to the Ministry of Defense of the Republic of Latvia. The contract for three TPS-77 MRRs was signed in 2015 and aims to improve Latvian Armed Forces' low-level flight surveillance and identification capabilities, leading to enhanced early warning and situation awareness.

According to Lockheed, TPS-77 MRR has a multi-role single scan technology allows operators to select multiple missions for the radar at a single time, such as long-range or medium-range low-level flight surveillance. As the radar rotates through each 360-degree scan, the system automatically adjusts to the selected mission. 

Latvia's variant of this high-performing radar can be truck mounted for operation at remote sites or dismounted for use at fixed sites.
