Boeing actually developed three X-32s, the USAF X-32, the Marine Corps STOVL model and a carrier-capable version. First flight of X-32A was on 18 September 2000. The X-32B STOVL made its first hovering flight on 7 March 2001 and on 13 April 2001 it made the first airborne transition from conventional to STOVL mode and back again.
The concept behind the Joint Strike Fighter program was to replace most F-16s, Harriers, F/A-18s and other aircraft in service with US Military and other friendly air arms.
The X-32B's vertical thrust system was similar to the Harrier's. Vectoring nozzles were under wing around the CG. The pitch-axis vectoring nozzle at the tail was different.
Boeing never built the projected carrier-based version. The X-32A served for both USAF and USN missions. (Incidentally, a Marine Corps Aviator is considered a Naval Aviator). No real help for Glenn here, just more background.
