Key point: Synthetic Aperture Radar, or SAR, uses electromagnetic signals or “pings” to deliver a picture or rendering of the terrain below, allowing for better target identification.
The Air Force is performing key maintenance on the F-22 Raptor's stealth materials while upgrading the stealth fighter with new attack weapons to include improved air-to-air and air-to-surface strike technology, service officials said.
Months ago, the Air Force contracted Lockheed Martin to perform essential maintenance to the F-22's low-observable stealth coating to ensure it is equipped to manage fast-emerging threats.
Lockheed Martin completed the first F-22 Raptor at the company’s Inlet Coating Repair (ICR) Speedline, a company statement said.
"Periodic maintenance is required to maintain the special exterior coatings that contribute to the 5th Generation Raptor’s Very Low Observable radar cross-section," Lockheed stated.
The increase in F-22 deployments, including ongoing operational combat missions, has increased the demand for ICR. Additionally, Lockheed Martin is providing modification support services, analytical condition inspections, radar cross section turntable support and antenna calibration.
Also, Air Force officials have told Scout Warrior that, by 2019, the service will begin upgrading F-22 functionality for the AIM-120D and AIM-9X Air-to-Air missiles as well as enhanced Air-to-Surface target location capabilities. The F-22 currently carries the AIM-9X Block 1 and the current upgrade will enable carriage of AIM-9X Block 2.
Raytheon AIM-9X weapons developers explain that the Block 2 variant adds a redesigned fuze and a digital ignition safety device that enhances ground handling and in-flight safety. Block II also features updated electronics that enable significant enhancements, including lock-on-after-launch capability using a new weapon datalink to support beyond visual range engagements, a Raytheon statement said.
