The OA-4AR Skyhawk is the two-seat variant of the modernized A-4AR Fightinghawk, developed for the Argentine Air Force (Fuerza Aérea Argentina) in the late 1990s through an upgrade program led by Lockheed Martin. Based on the rugged airframe of the A-4M Skyhawk, the OA-4AR combines structural reliability with modern avionics derived from fourth-generation fighter jets.

Primarily designed for advanced training and Forward Air Control (FAC) roles, the OA-4AR retains the full operational capability of the A-4AR while incorporating a dual-seat cockpit. This configuration allows for use by an instructor pilot or mission systems operator, making it ideal for pilot conversion, tactical coordination, and complex mission support.

Like its single-seat counterpart, the OA-4AR is equipped with the AN/APG-66V2 radar (a variant used in early F-16s), a modern Head-Up Display (HUD), Radar Warning Receiver (RWR), secure datalink, and a Night Vision Goggle (NVG)-compatible cockpit.

Although it cannot employ advanced guided weapons such as AMRAAMs or JDAMs, the OA-4AR can deploy AIM-9L Sidewinders, Mk 82 free-fall bombs, rocket pods, and ECM pods, making it effective in close air support (CAS), interdiction, and light air defense missions.

Powered by the Wright J65-W-20 turbojet, the OA-4AR reaches speeds of up to 670 mph (1,078 km/h) and can carry up to 8,200 lbs (3,720 kg) of ordnance on five external hardpoints. Its compact size and low radar cross-section make it a difficult target during low-level strike operations.
