The Latvian Ministry of Defence (MoD) has taken delivery of the first of three Lockheed Martin TPS-77 Multi-Role Radar (MRR) air systems, following the completion of a successful site acceptance test (SAT) in Ventspils on Latvia’s Baltic Sea coast on 1 March.
The SAT – which is designed to validate the radar system’s performance – was conducted with assistance from the US Army’s 227th Aviation Regiment, 1st Air Cavalry Brigade, and marks the first deployment of a TPS-77 MRR in Europe. The test in Ventspils – which validated various radar altitude verifications – will be the only SAT conducted for the new radars; the two remaining radars will undergo an operation checkout following their future delivery to Latvia, a Lockheed Martin spokesperson told Jane’s . The spokesperson declined to comment on the delivery timeline for the two remaining TPS-77 MMRs, noting, “We are not able to disclose specific dates but we are on schedule to deliver the remaining two radars on time.”
Latvia signed a contract of undisclosed value for the three TPS-77 MRRs in October 2015 under the auspices of an ongoing co-operative radar development and training umbrella agreement between Latvia and Lockheed Martin. This began with the delivery and installation of the first of three AN/TPS-77 static long-range air surveillance radars in the early 2000’s; the remaining two AN/TPS-77 were delivered/installed in 2011 and 2013 respectively. As part of the delivery TPS-77 MRR programme, Lockheed Martin has engaged with local Latvian industry for component procurement and production.
