Three contractors will help the US Navy develop plans to replace its Lockheed EP-3E Aries II fleet with an all-new aircraft and perhaps develop an expanded mission role.
The navy on 6 February awarded $1.25 million contracts to teams led by Boeing/Argon, Lockheed Martin and Northrop Grumman/L-3 Communications. Other known bidders, including EADS North America and Raytheon, did not receive contracts, but will not be excluded from a future competition.
"These contractors will help us determine the technical criteria necessary to build a strong foundation for the EPX programme," says Capt Joe Rixey, the USN's maritime patrol and reconnaissance aircraft programme manager.

Boeing has confirmed plans to offer an electronic intelligence version of its developmental 737-based P-8A Poseidon maritime surveillance and strike aircraft.
But the pending EPX competition has also drawn interest from other platform suppliers, including Airbus, Embraer and Gulfstream. The USN has previously called for a new fleet of 14-19 aircraft to replace its EP-3s.
The navy describes EPX as a "manned multi-mission, multi-intelligence, surveillance, reconnaissance and targeting platform", co-ordinating with the still-undetermined Broad Area Maritime Surveillance unmanned air vehicle and the manned P-8A.
The three teams must deliver their study results within a year, with these to inform the USN's evolving acquisition strategy. A contract award is tentatively scheduled for fiscal year 2011.
