The US Navy has assessed a scaled-down version of the Surface Electronic Warfare Improvement Program (SEWIP) system for integration on its future littoral combat ships (LCS).

Designated as AN/SLQ-32C(V)6, the evolutionary development block upgrade programme for the SLQ-32 Electronic Warfare (EW) System is currently in its early development phase.

It aims to offer LCS with an enhanced electronic warfare suite to increase defence capabilities of the vessels.

Above Water Sensors (PEO IWS 2.0) major programme manager captain Doug Small said: "This system is another example of the close partnerships to deliver a tremendous improvement in warfighting capability to our sailors.

"The upgrade programme will widen the threat detection range of the Arleigh Burke-class guided missile destroyer."

"By maintaining commonality with SEWIP Block 2, we are able to simultaneously reduce life-cycle sustainment costs for the fleet."

Integration of the upgraded antenna, receiver and combat system interface, provides the SEWIP system with enhanced signal detection, measurement accuracies and classification, and alleviates electromagnetic interference.

The upgrade programme will widen the threat detection range of the Arleigh Burke-class guided missile destroyer.

The effectiveness of the system's capabilities will be assessed as part of an at-sea demonstration on-board the navy's USS Freedom (LCS 1) in December, offshore San Diego.

To be installed on surface combatants featuring the existing active version of the SLQ-32, the SEWIP Block 3 will boast enhancements for the electronic attack by offering integrated countermeasures against radio frequency-guided threats and extending frequency range coverage.
