    Bell AH-1 SuperCobra Attack Helicopter (1971)

    Bell AH-1 SuperCobra Attack Helicopter (1971)

    The Bell AH-1 SuperCobra attack helicopter represents an evolved, twin-engine variant of the original Vietnam War-era AH-1 Cobra attack helicopter line.

    Staff Writer (12/5/2014): The AH-1 "SuperCobra" is a further evolution of the original Vietnam War-era AH-1 "Cobra" born in the 1960s. The SuperCobra is differentiated primarily by its twin-engine configuration compared to the single-engine nature of the Cobra system. The SuperCobra achieved its first flight in 1969 and entered service (as the AH-1J) in 1971. This was followed by the modernized AH-1W in 1986. To date, some 1,270 examples have been produced and the type stocks the inventories of the United States (Marines), the Iranian Army, South Korea, Taiwan and Turkey. The AH-1W is being superseded by the newer AH-1Z "Viper" standard.

    Outwardly, the SuperCobra family retains much of the external appearance of the original Cobra design including its two-person, stepped cockpit creating a slim profile when viewed from the front. The powered, chin-mounted turret has also been carried over as had the Cobra's fixed, skid landing equipment. The pilot is seated in the rear, elevated cockpit with the weapon's officer in the front cockpit (flight and weapons controls are doubled). The engine pairing drives a two-bladed main rotor and two-bladed tail rotor (the latter affixed to the starboard side of the vertical tail fin. Like the Cobra, the SuperCobra can undertake a variety of battlefield roles that go beyond its base anti-armor capabilities. It can be used in close support of friendly forces, support special forces operations and provide security for convoys. Armed reconnaissance allows the aircraft to both track and engage unsuspecting foes at range through cannon fire, rockets and missiles.

    The SuperCobra is outfitted with a 20mm M197 3-barreled Gatling cannon fitted to a powered M97 turret assembly under the nose as standard. This system is afforded 750 rounds of 20mm projectiles. The SuperCobra is also cleared to fire 2.75" (70mm) Mk 40 or Hydra 70 series rockets from multiple-shot pods. It can replace these with the larger 5" (127mm) "Zuni" series rockets fired from four-shot LAU-10D/A series launcher systems. Anti-armor sorties are managed by TOW missile launchers (four-shot launchers) and AGM-114 "Hellfire" anti-tank missiles (M272 launchers). MIssiles are limited to the outboard underwing hardpoint. To counter low-flying aerial threats, the platform can also field the AIM-9 Sidewinder short-range missile at each wingtip. External fuel tanks can also be fitted to help improved operational ranges.
