The modest proposal....The USAF should consider bringing back the Jolly Green Giants in the form of the CH-53K for their Para-Rescue Mission.
If the pivot to the Pacific is real, and if over water rescue of aircrew, not to mention the nightmare scenario of a C-130 or other large transport going down in the water, then its time for something larger than a UH-60.
The issue for the Marine Corps is obvious. The CH-53K won't survive in this budget environment unless another service buys. Whether that's the USAF for the rescue mission or the US Navy for mine hunting and heavy lift, its going to need partners.
