The Government Accountability Office has denied Raytheon's bid protest of the Navy's award to Lockheed Martin for the Ship Self Defense System.
A GAO official confirmed the decision to Inside Defense today.
Raytheon, in a September statement to Inside Defense confirming it had filed the protest with GAO, cited "procedural errors in the competition."
The protest followed the Navy's Aug. 15 announcement that it awarded Lockheed Martin's rotary and missions systems business an initial award of $56 million for "combat system engineering support on the Ship Self Defense System." The contract is worth up to $637.6 million through 2028.
"The SSDS combat system engineering agent/software design agent primary deliverables will be SSDS tactical computer programs, program updates and associated engineering, development and logistics products," the contract announcement reads. "This contract will manage the in-service SSDS configurations as well as adapt and integrate new or upgraded war-fighting capabilities."
A spokesman for Raytheon confirmed the company learned of the decision today. The company has historically built the SSDS for the Navy's aircraft carriers and amphibious ships.
“The details remain under protective order. We plan to review the decision when it becomes available, and will determine next steps at that point,” Ian Davis told Inside Defense in a statement.
Naval Sea Systems Command, which is the contracting authority, declined to comment.
"Our team can immediately begin the important work of engineering and delivering a world-class integrated combat system for the carriers and amphibious ships of the United States Navy," Lockheed Martin said in an email.
