(USAF). Originally designated NF-16D, the aircraft was redesignated X-62A on 14 June 2021 as part of an upgrade to a
Skyborg, with System for Autonomous Control of Simulation (SACS).
X-62A remains on the curriculum of the Air Force Test Pilot School as a practice aircraft for test pilots.

The NF-16D VISTA testbed aircraft incorporated a multi-axis thrust vectoring
Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket, or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the ve ...

situation. As a result, the aircraft is supermaneuverable, retaining pitch and yaw control at angles of attack beyond which the traditional control surfaces cannot change attitude.

fairing running the length of the fuselage aft of the canopy and a heavyweight landing gear derived from the Block 40 F-16C/D. The fairing houses most of the variable-stability equipment and test instrumentation. The heavyweight gear permits simulation of aircraft with higher landing sink rates than a standard F-16.

at Edwards Air Force Base. It is regularly used in student curriculum sorties, special academic projects, and flight research.[ As of 14 June 2021 VISTA is in the midst of upgrading. In addition to replacing the VISTA Simulation System (VSS) with a newer, upgraded version of the same system, a System for Autonomous Control of Simulation (SACS) will be added in order to operate X-62A as a Skyborg. One application is as autonomously piloted aircraft, perhaps as robotic wingman to a manned aircraft.][
