Project description:

Elsis TS together with partners – Italian defence sector companies Leonardo S.p.A., GEM Elettronica, successfully implemented the project of modernization of radars of patrol ships of the Lithuanian Naval Forces.

The core of the system is GEM Elettronica’s Columbus MK2 3D multi-mission radar purposely designed for coastal surveillance and shipborne applications, created using the latest technologies, ensuring low radiation detection, system longevity and automated work. It is a compact and advanced radar system for short- and medium-range air and surface contact monitoring and target designation for ship’s weapon systems.

The new radar systems were installed on Lithuania’s Flyvefisken‐class (Standard Flex 300) offshore patrol vessels (OPVs) Žemaitis (P11)Dzūkas (P12)Aukštaitis (P14), and Sėlis (P15).

The main role of the new equipment is to ensure safety of the ships when navigating in narrow passages (e.g., straits, port channels) and open sea, and search and rescue missions. The systems will help detect objects as far as 100 kilometres way. The dual function of the radars is detection and tracking of surface and airborne targets which will enable the use of currently integrated weapons on different types of targets with accuracy, including under especially adverse hydrometeorological conditions during the light and the dark part of the day. The installed radars also have integrated IFF (friend or foe) identification antennas.

During the project implementation, Elsis TS provided essential services, including:

  • Production of cables according to the standard IPC/WHMA-A-620B (Requirements and Acceptance for Cable and Wire Harness Assemblies) developed by Wiring Harness Manufacturers Association (WHMA), the only industry-consensus standard prescribing practices and requirements for the manufacture of Cable, Wire and Harness Assemblies, describing materials, methods, tests, and acceptability criteria for producing crimped, mechanically secured, or soldered interconnections and the related assembly activities associated with cable and harness assemblies;
  • Production of mechanical adapters – radar antenna holders and console mounting adapters;
  • All installation works of radar systems – control equipment, cables, electrical connections, consoles, additional screens, and IFF antennas.
