Lockheed Martin has completed its first maintenance and repair of the special exterior coatings of an F-22 Raptor's inlets.

The coating contributes to the 5th-generation Raptor's Very Low Observable radar cross-section, or stealth, properties.

The work was conducted at the company's Inlet Coating Repair Speedline facility in Marietta, Ga., built under a contract from the U.S. Air Force.

The F-22 repaired had arrived at the facility in early November. A second aircraft arrived in early December 2016 and a third late last month.

Lockheed Martin said a total of 12 Raptors are to undergo the inlet repairs but a follow-on contract is anticipated.

Lockheed Martin provides modification support services, analytical condition inspections, radar cross-section turntable support and antenna calibration in addition to the inlet repairs.

Boeing receives $983M contract for Air Force One engineering
Washington (UPI) Feb 1, 2017 –

Boeing Aerospace has received a $983 million order from the U.S. Air Force to perform engineering services for Air Force One and various other aircraft.

The contract tasks the company with performing services for VC-25, E-4B, C-32A, C-40B/C, E-8C, and NT-43 aircraft. Boeing will also provide analysis and technical instructions needed to overcome maintenance issues.

Most of the services are for military passenger planes used by high-ranking U.S. government officials. The VC-25, or Air Force One, is built specifically for transporting the president of the United States.

Boeing's contract award follows months of tension between the company and President Donald Trump over the cost of the Air Force One program. Before entering office, the president threatened to cancel the ongoing contract with the aerospace manufacturer in December.

Work will be performed in Oklahoma City, Okla., and is expected to be complete by the end of January 2027.

According to the U.S. Department of Defense, the contract award was the result of a sole-source acquisition. Boeing received $61.8 million in Fiscal 2017 operations and maintenance funds at the time of the award. The Air Force Life Cycle Management Center in Oklahoma is listed as the contracting activity.
