In preparation for its Initial Operational Test and Evaluation (IOT&E), Northrop Grumman’s first E-2D Advanced Hawkeye test aircraft, known as Delta One, has successfully completed its first land-based catapult launch tests – a required phase of testing prior to fleet introduction. Both E-2D System Development and Demonstration (SDD) aircraft, Delta One and Delta Two, are currently undergoing shore-based carrier suitability testing at Naval Air Station Patuxent River, Md., conducted by the U.S. Navy’s Air Test and Evaluation Squadron 20 (VX-20).

Prior to joining the carrier fleet, all naval aviation aircraft undergo carrier suitability testing. The bulk of this testing involves catapult and arrested landing structural tests, as well as the interoperability between the aircraft and the carrier.

In the cockpit for the first E-2D Advanced Hawkeye catapult test were Northrop Grumman Flight Test Pilot Les Ryan, and Dan Carrigg, Wyle flight test pilot. “There is nothing more exhilarating than being ‘shot’ off the deck of a carrier at more than 100 miles per hour,” said Ryan. “This phase of testing is critical to ensure that the aircraft can structurally handle the rigors of carrier operations. We completed multiple launches and, during each one, Delta One performed as expected — with no noted anomalies.”
