Lockheed Martin eyes common architecture for F-35, F-22

Lockheed Martin is looking at revamping several of the F-22's most critical systems with hardware from the F-35.
The initiative would create a common architecture that links upgrades of the radar, electronic warfare suite and communications, navigation and identification (CNI) system to both aircraft.
The concept requires "significant initial investment", but "could yield some cost savings in the long term", the manufacturer says.
