The Tory II-A reactor had a power rating of 155 megawatts. This translates to 207,859 horsepower. The J-58 produced 160,000 horsepower giving it 120 Megawatt power rating. If the Tory II-A had the same thrust to megawatt ratio as the 500 megawatt Tory reactors then it had 10,800 pounds of thrust. This is an interesting result in that at 10,800 pounds it is nearly the same thrust as the J-57 used in the first U-2's. The Tory II-A also had similar dimensions to the J-57.

Given the fact that the U2-A only weighed 8 tons (or 3.125 times less than 25 tons); it had the power to go well over Mach 2 at sea level. But since it was flying over 100,000 feet where air resistance is practically nil. The atomic U2-A had the power to travel at 21,642 mph or Mach 32. So, it appears as though what Col. L Fletcher Prouty claimed about the U2 "spy" plane was true. Although he left out the nuclear part. He did make odd claims about the U2 being hydrogen supplemented with a tank approximately the size of a fire extinguisher. He was dog whistling to those in the know about the U2-A being nuclear powered. So, his claims about Gary Powers being set up were true. Because the Soviets did not have the ability to shoot down the U2-A in their wildest dreams.

Prouty does look  down and to his right when he makes the claim @08:00 minutes that the U2 was hydrogen powered. He is making excessive hand gestures throughout the video. So, he appears to be lying when making these statements, using the traditional eyes to the right or the new excessive hand movement standard of lying.

Interestingly the SNAP 8 reactor was about the size of fire extinguisher.
