AH-1Z Viper

The US Marine Corps’ marinized attack helicopter — a twin-engine, tandem-seat “Zulu Cobra” that delivers heavy fires from the sea and forms the rotary-wing backbone of Marine Air-Ground Task Force expeditionary operations.

Overview

The Bell AH-1Z Viper is the current attack helicopter of the United States Marine Corps. Developed as part of the H-1 upgrade program alongside the UH-1Y Venom utility helicopter, the AH-1Z replaced the legacy AH-1W SuperCobra with a modernised, 84-percent-common airframe that simplifies shipboard logistics and sustainment. Fielded entirely by USMC light-attack helicopter squadrons and a small number of foreign operators, the Viper provides close air support, armed escort, anti-armor fires, and armed reconnaissance for expeditionary forces operating from amphibious ships or austere forward bases.

Development

Bell launched the AH-1Z as the attack half of the Department of the Navy’s H-1 Upgrade Program, which aimed to field a marinized attack/utility pair with high-commonality airframes and drive-trains. The Viper first flew in 2000, according to Wikipedia, and achieved initial operational capability with the USMC in 2010–2011. Production ran for the USMC until November 2022, with the final USMC airframe delivered that month. The National Interest notes that the Viper retained the SuperCobra’s 20-mm cannon and marinised construction while adding a four-blade composite rotor, glass cockpit, modern sensors, and dramatically improved speed and range. Export orders from Bahrain and the Czech Republic followed the USMC fleet completion.
