Some infos about Convairs nuclear powered ground effect machines.
"Development work on large nuclear-powered GEM's is being
carried on by Convair under Navy contract. These units would be
for long over-ocean flights. A single continuous annular Jet
would be provided along the periphery of the vehicle. The base
pressure would be around 30 psf. A platform 720 feet by 245 feet
and a 400-foot diameter circular unit are being considered. The
circular unit would be 62.5 feet high at the tail fins; a gross
weight of 4 million pounds with a payload of 500 tons; speed of
100 knots. Range, 3000 miles, and a hovering altitude of about
12-15. feet."
