The Latvian National Armed Forces (NAF) will finalise the delivery of the first TPS-77 Multi-Role Radar (MRR) by testing the system’s air surveillance capabilities, the Latvian Ministry of Defence (MoD) announced on 8 March.
The Latvian MoD signed a contract with Lockheed Martin for the production of three TPS-77 MRR units in 2015 to enhance the air surveillance capabilities of the Latvian Army.
The Latvian variant of the TPS-77 MRR can be truck mounted for operation at unprepared sites or dismounted for use at fixed sites.
The TPS-77 MRR’s multi-role single scan technology allows operators to select specific roles for the radar such as long range or medium range low-level flight surveillance in specific sectors. As the radar rotates through each 360 degree scan, the system automatically adjusts to the operator selected mission. Changes can be easily made, and once the radar is set, no further operator inputs are required.
The TPS-77 MRR uses Gallium Nitride technology, which enables the radar’s high power amplifiers to consume much less power, lowering life-cycle costs and extending the useful life of the radar.
Latvia already has three AN/TPS-77 radars at the Čalas, Lielvārde and Audriņi surveillance radar stations. The radars have improved the airspace security and efficiency of air traffic surveillance and coordination for search and rescue operations.
Clavister CyberArmour, an integrated defence cybersecurity system, will be used on BAE Systems Hägglunds’ CV90 platform in deployments with a Scandinavian country, as well as in an eastern European nation.
The tactical satellite (TacSat) is an intelligence, surveillance and reconnaissance (ISR) system and will participate in exercises in 2025.
The airborne three-domain, the two ground-based and the ¼ ATR OpenVPX-based cross-domain systems were engineered to provide real-time security across multi-domain operations.
DARPA’s Mission-Integrated Network Control (MINC) programme was set up to develop an autonomous tactical network and enable critical data flow in contested environments.
Why space is an essential part of modern military capabilities
Defence-secure mixed reality headsets can save hours, or even weeks, of travel time to fix defunct equipment or get subject experts effectively “on-site” where they are needed.
