Hi Tailspin Turtle!

Thanks for info about this competition  between McDonnell and Sikorsky, with the later as a winner. The resulting product - heavy H-37 was my long time favorite. It has a distinctive shape and some interesting developmennts, like Sikorsky S-60 and (new to me) British
Westland Westminster.

Seems, that idea of heavy helicopters became more clear with turbine engines' intriduction.

"We can't [assume] that having 1,550 deployed strategic nuclear weapons under the New START Treaty somehow deters all our adversaries. It doesn't," the general said.

Why we should have decoupled our arsenal from that of the USSR/Russia after the Cold War and sized it for our and our allies security needs. Which IMHO was START I - 1200 launchers and 6000 warheads.

Have you read the article?
In context it's very clear he is not advocating for larger numbers of warheads and delivery systems.
He's advocating for modernisation of the triad and for the need for complementary capabilities (like cyber attack/ defence etc.)

Was the Model 78 ever designed to be a competitor to the Chinook?  Pity it was never built.

The Navy issued contracts to both McDonnell and Sikorsky for this marine assault mission, designated HRH and HR2S respectively. McDonnell's contract was subsequently terminated. The resulting Sikorsky helicopter is better known as the H-37, its Army designation. As Mark noted, this program was almost a decade earlier than the Chinook.
