(IAF), Lockheed Martin was offering the customized F-16IN Super Viper. The F-16IN is based closely on the F-16E/F Block 60 and features conformal fuel tanks, an AN/APG-80 AESA radar, a GE F110-132A engine with FADEC controls, an electronic warfare suite, an infrared search and track (IRST) sensor, an updated all-color glass cockpit, and a helmet-mounted cueing system. Lockheed Martin and the United States government intensively lobbied for India's US$10 billion contract for 126 fighter jets. Ashton Carter, chief of The Pentagon's acquisition department, even raised the possibility of United States offering the F-35 Lightning II to India as a follow-on to the F-16IN. The IAF extensively evaluated the F-16 which included field trials in hot weather conditions and in high-altitude mountain ranges. In April 2011, the IAF rejected the F-16IN's bid in favor of either the Eurofighter Typhoon or Dassault Rafale. In January 2012, the Dassault Rafale finally emerged as the winner of this US$10.5 billion deal for 126 fighter jets. In September 2015, Lockheed offered to produce F-16s in India as a part of the Make in India programme by Prime Minister Narendra Modi and talks began in February 2016 for a potential deal. F-16IN lost in the competition with JAS-39 Gripen E, when Lockheed retired from production in India, and decided to move production line from Fort Worth (Texas) to Greenville (South Carolina). As of July 2017, Lockheed Martin has agreed to sign a letter of intent with the Indian defence firm Tata Advanced Systems Limited to manufacture the jets in India if the Indian government accepts their tender for India's request for a purchase of single engine aircraft to replace its aging Mig fighters. The new production line can be utilised to supply jets to India as well as for exporting them overseas. Philippines The F-16C/D variants were first offered to the Philippine Air Force in 1992, and partook with several international competitors in a tender in 1995. This tender was however cancelled as a result of the 1997 Asian financial crisis. In December 2011, the Department of National Defense (DND) and Department of Foreign Affairs (DFA) were tasked to formally request at least a squadron of 12 ex-USAF F-16C/D fighter jets, most probably Block 25 or 30, which would be refurbished to either Block 50 or 52 standards. This was discussed during the US-Philippines "2+2" Meeting on 30 April 2012. The Philippine government would pay for
