Customs and Border Protection (CBP) last Friday awarded Northrop Grumman [NOC] a potential $896.1 million contract to provide maintenance and logistical support services for its P-3 surveillance aircraft

Lockheed Martin [LMT] was the incumbent for the work.

Initial funding under the award is $3.4 million and the contract includes a four-month phase in, a one-year base period, nine one-year options, and a six-month extension option, CBP said in a contract notice posted on the government’s procurement site,

CBP said that the contract will allow its Office of Air and Marine Operations to keep its fleet of P-3 operations to conduct their core missions of interdiction, investigation, domain awareness, contingency operations and national taskings. Work under the contract will take place in Jacksonville, Fla., Corpus Christi, Texas, and Lake Charles, La.

CBP operates two variants of the Lockheed Martin-built P-3, one for long-range tracking and the other for airborne early warning and detection.

Lockheed Martin in 2009 won a potential 10-year, $822 million contract to provide maintenance and repair services for CBP’s fleet of P-3 aircraft.

CBP said it received three proposals for the new contract.
