Bell AH-1J SuperCobra

The Bell AH-1 SuperCobra is a twin-engine attack helicopter based on the United States Army's single-engine AH-1 Cobra. The twin Cobra family, itself part of the larger Huey family, includes the AH-1J SeaCobra, the AH-1T Improved SeaCobra, and the AH-1W SuperCobra. The AH-1W has been the backbone of the United States Marine Corps's attack helicopter fleet, but is being replaced by the Bell AH-1Z Viper.
