Very well done.sir! You've got it!!

The HH-60H and HH-60J were co-developed making use of expensive fuel
"plumbing" modifications to the SH-60B that were necessary to create
the HH-60F (-F Variant).

With the provisions for extra fuel (as you pointed out) the HH-60J
could meet the 300 NM, loiter 45 minutes, hoist 6 people and returnr
with reserves.

The FLIR Systems Inc. (FSI) Star Safire EO/IR sensors are being
installed now. The other improvements are as you stated.

The HH-60J Jayhawk development began in 1986 based on the HH-60H Rescue
Hawk airframe. The Jaywawks were delivered to the US Coast Guard in the
early 1990s. The HH-60J has a radar for search/weather that gives its
nose a distinctive look. A forward-looking infared (FLIR) sensor turret
can be mounted below its nose.* It can carry three 120 US

A total of 42 Jayhawks were built by Sikorsky Aircraft Corporation with
35 in operation and another 7 in storage or support roles.^[3]

The HH-60Js began an upgrade program to convert them to medium range
responder helicopters in January 2007. with the new designation
"MH-60T". The program, called Deepwater Program will provide a glass
cockpit and other upgrades.^[4]

The MH-60T is modified with an airborne use of force package, including
weapons for firing warning and disabling shots, and armor to protect the
aircrew from small arms fire.
