The Lockheed Martin/Boeing F-22 Raptor, an all-weather stealth aircraft designed for the United States Air Force (USAF) in the 1990s, continues to be a significant asset. Despite being considered an unsuccessful program by some, the F-22 platform has potential for future service due to its open system architecture.

One of the first combat aircraft with this feature, the F-22's open system architecture allows for digital optimization and modular improvements. "Agile software development, open system architecture, and digital engineering methods are expected to work together to strengthen the platform further," according to Lockheed Martin.

A key capability of the F-22 is its connectivity with other platforms through Link 16. This enables data sharing and communication with various aircraft such as the F-35 Lightning II and F-15 Eagle. Lockheed Martin states, "The Link 16 transmit capabilities included in F-22 Raptor Agile Capability Release (RACR) Release 1 will enable the two-way exchange of J-series messages (Link 16) between the F-22 and other Link 16-enabled aircraft."

The F-22 also features four hardpoints that allow for payload customization. Each hardpoint can carry up to 5,000 lb (2,270 kg) of payload or a 600-US gallon drop tank. The internal weapons bay provides additional versatility based on mission requirements.

Sustainment efforts by Lockheed Martin and USAF ensure mission readiness through programs like Reliability, Availability and Maintainability Program (RAMP). The modernization line enhances capabilities while maintenance focuses on stealth coating repairs and engine upkeep. "About 50% of maintenance performed on the F-22 is related to repairing the low observable stealth coatings," notes Lockheed Martin.

Lastly, maintenance scheduling is streamlined through the Integrated Maintenance Information System (IMIS), which allows personnel to log completed tasks directly into a global database using a plug-and-play technique.
