According to Jane's:

  The HH-3E Jolly Green Giant (which was operated in the SAR and aircraft
  retrieval role by the USAF's ARRS - Aerospace Rescue and Recovery
  Squadron): range with max fuel and max reserves (30mins): 465 miles.

  The HH-53 Super Jolly Green Giant (Also operated by the ARRS): range
  with max fuel and reserves at optimum cruise: 306 miles.

  The CH-53C tactical variant was operated by the USAF 56th Special
  Operations Wing at Nakhon Phanom, Thailand, but without heavy lift
  rescue gear and inflight refuelling probe.

  The UH-1H Iroquoi "Huey": range with max fuel and max reserves at
  optimum cruise: 318 miles.


The HH-53 'Super Jolly Green Giant' was the successor to the HH-3.  It was
faster and had nearly triple the take-off weight of the basic 'Jolly Green
Giant'.  However, it had approx 150 miles less range that its predecessor.
To make up for this the HH-53 was fitted with an in-flight refuelling
probe.  In-flight refuelling for helos involves relatively slow air speeds
and low altitudes; a rather dangerous combination over enemy territory.

According to 'War Machine: Guide to The World's Assault Helicopters'
(ORBIS, 1984), USAF HH-3 and HH-53s were used in various "clandestine"
Army Special Forces operations, mainly for the delivery and extraction of
troops, but no missions involving such great distances (400 miles-plus)
are mentioned.
