Just a last bit follow…In 1935 The H 1 Racer set a speed record of 352 mph for that time with a Pratt & Whitney Twin Wasp Jr radial engine which produced 700 hp. The huge NACA cowling served to streamline and cool the huge engine of the day.
By 1941 the Focke Wuff Fw 190 enter service after numerous engine cooling issues. The Germans wanted to streamline the nose to get away from the NACA cowling Hughes H 1 used. The final design in 1945 could hit nearly 470 mph. at high altitude. (nearly 5 miles high) But to do this the Germans used a more powerful engine producing nearly 1700 hp.
Hugh’s had wanted to sell his H 1 technology to the US Government but they weren’t interested. By the later 30’s the Germans were realizing the potential.
Hughes H 4 Hercules (Spruce Goose) was another rejected solution to the submarine menace on the Atlantic. In operation it would have flown at lower altitude over the sea. (perhaps 100 ft as Hughes demonstrated when he flew it)
This is known as “ground effect”. A way of extending fuel mileage.
For troop transport we wouldn’t have lost men at sea due to submarines and delivering them to the war front would have been faster. For the logistics of
valuable cargo such as ammunition etc, it would have been safer & faster too.
Finally a fleet of H 4’s would have been faster to build and much cheaper given the abundance of Birch wood which wasn’t regulated by war time restrictions.
So often the media has painted Hughes up to be a wealthy playboy “wach-o”. which is a shame as anyone who would read about him would realize the visionary that he was. Of course “Big Industry” stood to profit immensely from war and they wouldn’t appreciate Hughes pairing down their profits with his better ideas. A trend we’ve witnessed in wars & skirminshes since.
Those of the “Greatest Generation” would remember Hughes for all of his contributions and when his name was associated with the Glomar I’m sure they
were happy he was still making a positive contribution in his closing years. .
