Protest Dance Continues as Raytheon fights to hold on to 3DELRR radar program

Raytheon Co. was awarded in October 2014 a development
contract to replace the Air Force's current TPS-75 radar, which
has been in service since the late 1960s. That award was
halted after Northrop Grumman Corp. and Lockheed Martin Corp.
filed protests. (U.S. Air Force photo/ Staff Sgt. Patrick Dixon)

"Raytheon filed an action … seeking to preserve the Air Force's contract award," said Raytheon spokesman Michael Nachshen. "We believe the Air Force awarded the procurement to Raytheon in a properly conducted bid process and we remain confident in our 3DELRR solution."
Raytheon (NYSE: RTN) won the $19.5 million development contract, which includes delivery of three initial defense radar systems. The value of the program is expected to grow to about $1 billion, once development moves into full-rate production, with the Air Force planning to buy 32 more radars.

Raytheon Files 3DELRR Suit Against Air Force
The Air Force selected Raytheon over Northrop Grumman and Lockheed Martin. Both competitors quickly filed protests with the Government Accountability Office (GAO), setting off a 100-day protest period in which the GAO investigated whether the Air Force properly selected its winner.
Days before that 100-day window was to run out, the Air Force voluntarily announced it would reevaluate the contract award, a move that likely signified the service expected the GAO to side with one of the protesting companies.
