Lockheed Martin A-4AR Fightinghawk
From Canadian Power Wiki
The Lockheed Martin A-4AR Fightinghawk is a major upgrade of the McDonnell Douglas A-4M Skyhawk attack aircraft developed for the Argentine Air Force and Argentine Naval Aviation which entered service in 1998. The program was named Fightinghawk in recognition of the F-16 Fighting Falcon, which was the source of its new avionics.
