The IFF interrogator is a sophisticated airborne defence system that provides a long-range, rapid early warning and detection capability, allowing discrimination between friendly and hostile aircraft. The Mode S system enables the aircraft to be used in controlled airspace.

The work was performed at Royal Air Force Waddington under Northrop Grumman's existing Sentry E-3D Whole Life Support Programme (WLSP), and is the most complex of a series of modifications the company has carried out to date for the Sentry aircraft fleet.

"This innovative system upgrade has eliminated the need for complete mission computer replacement, thereby providing the Ministry of Defence with a comprehensive, affordable solution to the Civil Aviation Authority's upgrade requirement," said John Parker, director, weapon system sustainment and modernisation, Northrop Grumman Technical Services. "The new, open architecture system also provides a foundation for future incremental hardware and software upgrades to support sustainment of the Sentry E-3D."

"Northrop Grumman partnered with the Sentry Project Team to develop and integrate this complex, critical capability," said Group Capt. Adam Northcote-Wright, Air ISTAR delivery manager, Defence Equipment and Support. "This combined effort delivered a cost effective Mode S solution that has achieved full operational capability across the U.K. Sentry E-3D fleet."

Northrop Grumman delivers the WLSP for the Sentry E-3D AWACS fleet and is on contract until 2025.
