Description
The Dassault Étendard IV is a transonic carrier-borne strike fighter developed by French manufacturer Dassault Aviation. Originating in the 1950s from Korean War lessons, the design evolved from proposals for French Air Force and NATO specifications. Following low interest in these initial designs, Dassault privately developed a larger version, designated Mystère XXIV, which attracted French Navy interest. A navalized prototype made its first flight on 24 July 1956. After evaluations of five pre-production aircraft, the French Navy ordered the type, receiving 69 Étendard IVM fighters and 21 Étendard IVP reconnaissance aircraft. Plans to replace the type with the SEPECAT Jaguar M were canceled in favor of the Super Étendard.
The Étendard IVM features a highly swept, folding wing designed for carrier storage, equipped with double-slotted flaps, spoilers, powered ailerons, and leading-edge droop flaps. It is powered by a single SNECMA Atar 08B turbojet engine delivering 43.16 kN (9,700 lbf) of thrust, which lacks an afterburner. The aircraft is transonic, exceeding Mach 1 only in a dive. Systems include a retractable nose-mounted refueling probe, a TACAN receiver, and a braking drogue parachute. Avionics consist of a nose-mounted Dassault Aida radar, an infrared sensor, and a SAAB bombing computer.
Standard armament consists of two internal 30 mm DEFA 552 cannons with 150 rounds per gun. The aircraft features four wing-mounted external hardpoints with a total payload capacity of 1,360 kg (3,000 lb). It carries AIM-9 Sidewinder and Matra Magic air-to-air missiles, Nord AS.20 and AS.30 air-to-surface missiles, Matra rocket pods with 18 SNEB 68 mm rockets, bombs, and drop tanks.
The French Navy was the sole operator of the type, receiving its first aircraft in December 1961. The aircraft deployed in 1962 aboard the Clemenceau-class carriers Clemenceau and Foch. The type was phased out of active combat roles in 1987. The final Étendard IVM fighters were retired in July 1991 from Squadron 59S, having accumulated 180,000 flight hours and 25,300 carrier landings. The Étendard IVP reconnaissance variant remained active until 27 July 2000, bringing the type's total service to over 200,000 flight hours.
