DOT&E highlights weaknesses in US Navy EW system testing

01 February 2019

The 2018 report from the Pentagon’s Director, Operational Test and Evaluation (DOT&E) has called on the US Navy (USN) to address critical gaps in its ability to realistically simulate anti-ship cruise missile (ASCM) seeker performance and approach profiles in support of Surface Electronic Warfare Improvement Program (SEWIP) testing.

Released on 31 January, the DOT&E’s annual scorecard suggests the shortfalls will severely limit the fidelity of initial operational test and evaluation (IOT&E) for the SEWIP Block 3 system. Being developed by Northrop Grumman, SEWIP Block 3 introduces advanced electronic attack (EA) functionality into the SEWIP architecture under the designation AN/SLQ-32(7).

In its assessment of electronic warfare (EW) test resources and environments, the DOT&E said a gap in the navy’s ability to realistically represent multiple ASCM seekers during test was initially identified in its 2013 annual report.
