The Curtiss XP-60B and XP-60C were experimental fighter aircraft developed by Curtiss-Wright Corporation during World War II.
Here is some information about these aircraft:
XP-60B
The XP-60B was the first of the two aircraft to be developed.
It was a low-wing monoplane fighter that was designed to be powered by an Allison V-1710 liquid-cooled engine.
The XP-60B was equipped with a 37mm cannon and four .50 calibre machine guns.
However, the XP-60B never made it past the prototype stage due to issues with its engine and development delays.
XP-60C
The XP-60C was an updated version of the XP-60B.
It featured a redesigned engine cowling and cockpit, as well as a new vertical tail.
The XP-60C was also powered by an Allison V-1710 engine, but it was equipped with a turbo-supercharger to improve its high-altitude performance.
The XP-60C was armed with four .50 calibre machine guns, but it was also intended to carry a 37mm cannon in the nose.
However, like the XP-60B, the XP-60C never entered production due to ongoing engine and development issues.
Overall, the XP-60B and XP-60C were both promising designs that ultimately failed to meet their performance goals.
The XP-60 project was eventually cancelled, and Curtiss-Wright went on to focus on other aircraft designs.
