Argentina Retires Last A-4 Fightinghawk Jets as F-16s Enter Service

The Argentine Air Force has withdrawn the last of its A-4AR and OA-4AR Fightinghawk jets, ending six decades of A-4 Skyhawk operations in the country. The retirement was announced at Villa Reynolds Air Base in San Luis province, home to the 5th Air Brigade, the final unit to operate the type.

The decision prioritizes operational efficiency and economic sustainability as the service introduces its first F-16 fighters. The announcement came one day after social media posts showed the aircraft's last operations, including final landings. Maintenance challenges had mounted in recent years despite earlier modernization efforts.

The retirement aligns with the arrival and initial flight operations of F-16AM and F-16BM aircraft. These secondhand jets from Denmark include 16 single-seat F-16AMs and eight two-seat F-16BMs, plus additional airframes for training and spares. Pilots continue familiarization flights at designated areas near Río IV.

The F-16s were approved for transfer by the U.S. government in October 2023. They were described by the U.S. Department of State as low-cost, high-performance multirole aircraft. The introduction marks a significant capability upgrade for the Argentine Air Force.

“Los F-16 comenzaron su actividad de vuelo en el Área Material Río IV, operando en sectores autorizados. Nuestros pilotos continúan su familiarización con el sistema de armas. Marine Corps A-4M and OA-4M airframes taken from storage. Deliveries to Argentina totaled 32 A-4AR single-seaters and four OA-4AR two-seaters beginning in the mid-1990s. Upgrades included the AN/APG-66 radar, AIM-9M Sidewinder compatibility, HOTAS controls, multifunction displays, and a new head-up display. Although more capable than original Vietnam-era Skyhawks, the Fightinghawks were pressed into an air-defense role after the retirement of Mirage fighters in 2015. The type was never intended as a dedicated fighter but filled the gap while the service sought replacements. British diplomatic efforts repeatedly blocked potential deals before the F-16 path opened.”

Argentina first received A-4Bs in 1966, becoming the jet's initial export customer. Additional batches of A-4Bs and A-4Cs followed in 1970 and 1976 for air force units at Villa Reynolds and El Plumerillo. The Argentine Navy operated A-4Qs from the carrier Veinticinco de Mayo, equipped for air defense and buddy refueling.

Operating at extreme range from mainland bases, the jets flew more than 200 combat sorties. They sank four British warships and damaged others despite lacking modern self-protection systems, losing 19 aircraft and 17 pilots in total. The navy retired its last A-4Q in 1988.

The original air force A-4s were withdrawn in 1999. With the Fightinghawk's exit, Brazil remains the only military operator of the A-4, though its fleet faces an uncertain future following the retirement of the carrier São Paulo. The A-4 continues in civilian service with private military contractors.

Companies such as Canada's Top Aces and Florida's Draken International use upgraded examples featuring AESA radars and infrared search-and-track systems for adversary training. These roles are expected to sustain the type's legacy even as it disappears from frontline military inventories.

The Argentine Air Force described the decommissioning as definitive, closing a chapter that began with the first A-4 deliveries 60 years ago.
