The Jayhawk is an HH-60, basically a Seahawk but without the heavy anti-sub kit and equipment. It is literally twice the size of the 76, in every way.
It has an MGW of 21,500 lbs, nearly twice that of the S-76C++ at 11,700.
The Jayhawk has two 1970 SHP engines, also twice the C++. The empty weight is also twice, but the payload is therefore twice.
It has about 350NM radius of action with 1/2 hour hover, and an auto-hover auto-approach SAR coupled control system.
