On 15 February 2012, Lockheed Martin unveiled a new version of their F-16 at the 2012 Singapore Airshow. The F-16 will feature enhancements including an AN/APG-83 active electronically scanned array (AESA) radar, an upgraded mission computer and architecture, and improvements to the cockpit – all capabilities identified by the U.S. Air Force and several international customers for future improvements. The new variant is dubbed the "Viper", which is intended to better operate with fifth-generation fighters, and should not be confused with Lockheed's F-16IN Block 70/72 "Super Viper", which was offered to India for the Medium Multi-Role Combat Aircraft competition and showcased at the 2009 Aero India Air Show. "The new F-16 will become the new F-16 baseline," said George Standridge, Lockheed Martin Aeronautics' vice president of business development. On 16 October 2015, the F-16V flew for the first time with an APG-83 Scalable Agile Beam Radar AESA, a new Center Pedestal Display, a modernized mission computer, Automatic Ground Collision Avoidance System, and many other upgrades. This can be fitted on new production F-16s or retrofitted on existing ones. The first of these were for Taiwan F-16A/B Block 20s. The upgrade of its 144 aircraft fleet started in January 2017 and is expected to complete by 2023.In 2019, Taiwan and the United States signed an $8 billion deal that would deliver 66 new-build Block 70 aircraft.
