context_page_description: The General Dynamics F-16 Fighting Falcon is a single-engine supersonic multirole fighter aircraft originally developed by General Dynamics for the United States Air Force. Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft. Over 4,600 aircraft have been built since production was approved in 1976. Although no longer being purchased by the U.S. Air Force, improved versions are being built for export customers. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation, which in turn became part of Lockheed Martin after a 1995 merger with Martin Marietta.
  The Fighting Falcon's key features include a frameless bubble canopy for better visibility, side-mounted control stick to ease control while maneuvering, an ejection seat reclined 30 degrees from vertical to reduce the effect of g-forces on the pilot, and the first use of a relaxed static stability/fly-by-wire flight control system which helps to make it an agile aircraft. The F-16 has an internal M61 Vulcan cannon and 11 locations for mounting weapons and other mission equipment.
context_section_description: F-16 models are denoted by increasing block numbers to denote upgrades. The blocks cover both single- and two-seat versions. A variety of software, hardware, systems, weapons compatibility, and structural enhancements have been instituted over the years to gradually upgrade production models and retrofit delivered aircraft.
  While many F-16s were produced according to these block designs, there have been many other variants with significant changes, usually due to modification programs. Other changes have resulted in role-specialization, such as the close air support and reconnaissance variants. Several models were also developed to test new technology. The F-16 design also inspired the design of other aircraft, which are considered derivatives.  Older F-16s are being converted into QF-16 drone targets.
  F-16A/B
  The F-16A (single seat) and F-16B (two seat) were initial production variants. These variants include the Block 1, 5, 10 and 20 versions. Block 15 was the first major change to the F-16 with larger horizontal stabilizers. It is the most numerous of all F-16 variants with 475 produced. Many F-16A and B aircraft have been upgraded to the Mid-Life Upgrade (MLU) Block 20 standard, becoming functionally equivalent to mid-production C/D models.
  F-16C/D
  The F-16C (single seat) and F-16D (two seat) variants entered production in 1984. The first C/D version was the Block 25 with improved cockpit avionics and radar which added all-weather capability with beyond-visual-range (BVR) AIM-7 and AIM-120 air-air missiles. Block 30/32, 40/42, and 50/52 were later C/D versions. The F-16C/D had a unit cost of US$18.8 million (1998). Operational cost per flight hour has been estimated at $7,000 to $22,470 or $24,000, depending on calculation method.
  F-16E/F
  The F-16E (single seat) and F-16F (two seat) are newer F-16 Block 60 variants based on the F-16C/D Block 50/52. The United Arab Emirates invested heavily in its development. It features improved AN/APG-80 active electronically scanned array (AESA) radar, avionics, conformal fuel tanks (CFTs), and the more powerful General Electric F110-GE-132 engine.
  F-16IN
  For the Indian MRCA competition for the Indian Air Force, Lockheed Martin offered the F-16IN Super Viper. The F-16IN is based on the F-16E/F Block 60 and features conformal fuel tanks; AN/APG-80 AESA radar, GE F110-GE-132A engine with FADEC controls; electronic warfare suite and Infra-red search and track (IRST) unit; updated glass cockpit; and a helmet-mounted cueing system. As of 2011, the F-16IN is no longer in the competition.  In 2016, Lockheed Martin offered the new F-16 Block 70/72 version to India under the Make in India program. In 2016, Indian government offered to purchase 200 (potentially up to 300) fighters in a deal worth $13–15bn. As of 2017, Lockheed Martin has agreed to manufacture F-16 Block 70 fighters in India with the Indian defense firm Tata Advanced Systems Limited. The new production line could be used to build F-16s for India and for exports.
  F-16IQ
  In September 2010, the Defense Security Cooperation Agency informed the United States Congress of a possible Foreign Military Sale of 18 F-16IQ aircraft along with the associated equipment and services to the newly reformed Iraqi Air Force. Total value of sale is estimated at US$4.2 billion.
  F-16N
  The F-16N was an adversary aircraft operated by the U.S. Navy.  It is based on the standard F-16C/D Block 30 and is powered by the General Electric F110-GE-100 engine, and is capable of supercruise. The F-16N has a strengthened wing and is capable of carrying an Air Combat Maneuvering Instrumentation (ACMI) pod on the starboard wingtip.  Although the single-seat F-16Ns and twin-seat (T)F-16Ns are based on the early-production small-inlet Block 30 F-16C/D airframe, they retain the APG-66 radar of the F-16A/B. In addition, the aircraft's 20 mm cannon has been removed, as has the ASPJ, and they carry no missiles. Their EW fit consists of an ALR-69 radar warning receiver (RWR) and an ALE-40 chaff/flare dispenser. The F-16Ns and (T)F-16Ns have the standard Air Force tailh
