Why was the HH-53 called "Super Jolly"?
Short answer
Because of size and color: the HH-53B's large green fuselage earned it the nickname "Super Jolly Green Giant," a reference to the smaller HH-3E "Jolly Green Giant," a stretched H-3 Sea King used in Vietnam for combat rescue. It was the largest, most powerful, and fastest helicopter in the USAF.

A nickname inherited from a smaller brother
The HH-53B's large green fuselage earned it the nickname "Super Jolly Green Giant", in reference to the smaller HH-3E "Jolly Green Giant", a lengthened version of the H-3 Sea King used in the Vietnam War on combat search and rescue missions. The first of the eight HH-53Bs flew on 15 March 1967. That aircraft, 66-14428, took off at Stratford, Connecticut, with Sikorsky test pilots James R. "Dick" Wright and Patrick A. Guinn in the cockpit. As a variant of the Navy and Marine Corps CH-53A Sea Stallion, the Super Jolly Green Giant was the largest, most powerful and fastest helicopter in the US Air Force inventory.
Eight years of rescues in Southeast Asia
The USAF introduced the HH-53 "Super Jolly Green Giant" configured for special operations and combat search and rescue. Between 1967 and 1975, the Air Force's HH-53 Super Jolly Green Giants were the main search and rescue helicopter in Southeast Asia. A limited sensor system for night and bad-weather flight called "Pave Low I", based on a very-low-light-level television sensor, was deployed to Southeast Asia in 1969 and was evaluated in combat on a Super Jolly.
Other roles
A few aircraft of a version later than the HH-53B were assigned to supporting the Apollo space program, on standby to recover a capsule in the event of an abort on the launch pad, which never happened. The YCH-53A from which the family started flew on 14 October 1964, and the first deliveries of production CH-53s to operational units began on 12 September 1966.
