SEA Wraps Up ASW System Trials with Portuguese Navy

SEA has completed sea trials of its Anti-Submarine Warfare (ASW) System with the Portuguese Navy as part of Exercise REPMUS (Maritime Unmanned Systems) 19.

The KraitSense low-profile passive sonar system detected, tracked and classified a submarine whilst deployed from a Portuguese Navy offshore patrol vessel (OPV).

An opportunity to test and evaluate the new capabilities for NATO countries, Exercise REP(MUS) 19 drew approximately 800 military participants from Portugal, the UK, Belgium, Italy and the USA alongside experts from both academia and industry. Exercise REP (MUS) 19 is a collaborative project, which allows industry, academia and the military to test the latest surface and subsurface capabilities in real military operating conditions.

SEA’s KraitSense System is a complete anti-submarine warfare solution, featuring an innovative low profile miniaturised acoustic array suitable for towed and static applications on both manned and unmanned vessels. With low power consumption, drag and weight, the capability offers significant cost efficiencies when compared to traditional line and towed arrays making it suitable for smaller ships and unmanned vessels, the company explains.

Peter Hodgkinson, business development director at SEA said, “Exercise REP (MUS) 19 was the first end to end deployment of the KraitSense system and the feedback that we’ve received from military personnel at the event has been very positive. From the system’s ease of integration and installation to its unique operational configuration, the KraitArray flexibility, small footprint and ability to detect, track and classify a quiet electric submarine was a true demonstration of the solution’s capability.”

The exercise took place in Lisbon on 8 – 27th September and saw SEA’s KraitSense installed onto a Portuguese OPV in two days at the dockside. To enable the effective analysis of the ASW environment, SEA’s sonar analysis and integrated maritime awareness software (provided by OSI) was also installed to provide a fully integrated solution fully integrated with the vessel’s other data systems.

“The trial was also an opportunity for SEA to test a new long tow cable to help reduce the impact of engine noise that is generated by smaller vessels. We’re pleased to say that this was extremely successful, further demonstrating that KraitSense™ provides a cost-effective ASW solution for navies of all sizes,” added Hodgkinson.
