SALINA  —  Lockheed Martin (NYSE: LMT) announced that it recently completed a successful site acceptance test of a TPS-77 Multi-Role Radar (TPS-77 MRR), produced at its Salina plant and delivered to the nation of Latvia.

This marks an on-time delivery of the first of three radars to the Ministry of Defense of the Latvia as that Baltic region country seeks to strengthen its national defense.

The Latvian Air Force uses the TPS-77 MRR for airspace defense by increasing its low-level flight surveillance and identification capabilities, “leading to enhanced early warning and situation awareness that allows its armed forces to make more informed and efficient decisions in response to modern day threats,” Lockheed Martin said in a news release.

“This milestone is the most recent event in a 16-year partnership of radar development and training between Latvia and Lockheed Martin, including the 2015 contract for three TPS-77 MRRs,” the defense contractor added.

The financial terms of the contracts were not disclosed.

“Acquisition of the TPS-77 MRR is a huge investment in the strengthening of combat capabilities of the National Armed Forces, enabling the Latvian army to address current security challenges with appropriate response tools. Surveillance, especially low-level flight surveillance and identification is a vital part of Latvian airspace surveillance capabilities. New MRR technology is compatible with other types of radars used by other countries,” Latvia’s Minister for Defence, Raimonds Bergmanis, said in the Lockheed release.

The TPS-77 MRR is the latest version in Lockheed Martin’s product line of surveillance radars. Its 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. Changes can be easily made if the system is moved or mission is changed, according to the company.

Latvia’s version of this radar can be truck mounted for operation at remote sites or dismounted for use at fixed sites.

As part of the TPS-77 MRR program, Lockheed Martin said it has worked with local Latvian industry for procurement and production.
