Which helicopter is referred to as the Cobra and serves in the United States Marine Corps?

The AH-1W is referred to as the Cobra and serves in the United States Marine Corps. This particular helicopter is part of a long lineage of attack helicopters that have played a critical role in Marine Corps aviation since the Vietnam War. The AH-1W features advanced avionics and weapon systems, making it capable of performing a variety of missions, including close air support and anti-armor operations.

While the AH-1Z, which is a modernized version of the Cobra, is another variant in the same family, the original designation most commonly recognized as "Cobra" is the AH-1W. The other helicopters listed, such as the MH-53E and HH-60H, serve different roles and are not associated with the Cobra lineage. The MH-53E is a heavy-lift transport helicopter, while the HH-60H is a search and rescue variant of the Sikorsky Black Hawk helicopter. Therefore, the AH-1W's historical significance and combat capability confirm its identification as the Cobra in the Marine Corps.
