The V8-99 Sphinx is a Joint Strike Force helicopter. It is a V-TOL transport, a redesign of the V-22 Osprey. It had windows and an emergency exit and was piloted by two people. After years of controversy and scrutiny, the tilt-rotor aircraft was finally perfected with the V8-99 Sphinx. The first generation of this aircraft saw action throughout the Middle East and Afghanistan. The V8-99 is the primary light/medium transport aircraft used by the JSF.
