Northrop Grumman And Ultra Demonstrate Unmanned ASW Capability

The Royal Australian Navy’s MH-60R Romeo helicopter conducts functional testing of the newly fitted Airborne Low Frequency Sonar System (ALFS) off the coast of Jacksonville, Florida.

Northrop Grumman Corporation and UK-based Ultra have equipped a modified, manned Bell 407 (acting as an MQ-8C Fire Scout surrogate) platform with Ultra sonobuoys, receiver and processor to complete an unmanned aircraft systems (UAS) anti-submarine warfare (ASW) capability demonstration.

This successful demonstration of the UAS ASW mission on October 29 was the first time a vertical takeoff surrogate unmanned aerial system (VTUAS) had been used to conduct a large area multistatic acoustic search.

The mission payload and effects were controlled from the ground with the resultant ASW picture disseminated to locations across the globe.

“Adding an ASW capability to Fire Scout’s existing multi-mission capabilities would further enhance this highly-versatile platform,” Dan Redman, Fire Scout maritime mission expansion lead, Northrop Grumman, said. “This ASW capability would offer commanders flexibility to employ not only UAS systems in this particular ASW role, but also utilize the increased availability of crewed aircraft more incisively against an expanded mission set. This would increase the total available effect of the manned/unmanned teamed force mix.”

While the US Navy has not yet identified a clear requirement for UAS ASW capability, it has reportedly shown interest in the development and ‘continues to support and monitor progress.’

“Operating prototype hardware in a high-pressure real-world environment can be challenging,” said Thomas Link, president of Ultra Maritime. “Our partnership will bring an innovative and leading ASW capability into operation, combining both manned and unmanned ASW systems that will help defend our warfighters and provide increased capability to our forces.”
