Unveiled in September 2017, the new KraitArray uses multi-module assembly philosophy and is now established in-service for use with ASV, AUV and small surface vessels.

This 150m KraitArray extends the range and increases the bearing accuracy enabling a full ASW capability on small ships and OPVs, according to the company.

As informed, the final proving trial is being fully-funded by a major defense contractor to prove its entire range of capability including new high-sensitivity transducers.

SEA explained that the KraitArray now delivers similar performance to much larger and costlier towed arrays but is more efficient to launch and recover, minimizing the footprint on the host vessel and handling requirements.

In addition, the modular construction of the KraitArray is easily repaired or replaced on board, the company added.

“The drive towards unmanned surveillance of the seas makes the lightweight KraitArray a valuable tool for underwater sensing. It is also an ideal solution for smaller vessels which are unable to accommodate a traditional heavy towed array,” Steve Hill, SEA Managing Director, commented.

The KraitArray will be available to view at the UDT Exhibition in Glasgow.
