sentences: A penetrator is a term referring to long-range bomber aircraft designed to penetrate enemy defenses.
 The term is mostly applied to aircraft that fly at low altitude in order to avoid radar, a strategic counterpart to the shorter-ranged tactical interdictor designs like the TSR-2 and F-111.
 However, the term can be applied to any aircraft that is designed to survive over enemy airspace, and has also been used for the penetration fighter designs that were designed to escort the bombers.
The McDonnell Douglas/General Dynamics A-12 Avenger II was a proposed American attack aircraft from McDonnell Douglas and General Dynamics.
 It was to be an all-weather, carrier-based stealth bomber replacement for the Grumman A-6 Intruder in the United States Navy and Marine Corps.
 Its "Avenger II" name was taken from the Grumman TBF Avenger of World War II.
General Dynamics Mission Systems is a business unit of American defense and aerospace company General Dynamics.
 General Dynamics Mission Systems integrates secure communication and information systems and technology.
 General Dynamics Mission Systems has core manufacturing in secure communications networks; radios and satellite technology for the defense, cyber, public safety, and intelligence communities.
An airstrike or air strike is an offensive operation carried out by attack aircraft.
 Air strikes are commonly delivered from aircraft such as fighters, bombers, ground attack aircraft, and attack helicopters.
 The official definition includes all sorts of targets, including enemy air targets, but in popular usage the term is usually narrowed to a tactical (small-scale) attack on a ground or naval objective.
 Weapons used in an airstrike can range from aircraft cannon and machine gun bullets, air-launched missiles to various types of bombs and even directed-energy weapons such as lasers.
 It is also commonly referred to as an air raid.
The General Dynamics F-111K was a planned variant of the General Dynamics F-111 Aardvark medium-range interdictor and tactical strike aircraft by General Dynamics, to meet a requirement for such an aircraft for the Royal Air Force.
The General Dynamics F-111 Aardvark was a supersonic, medium-range interdictor and tactical attack aircraft that also filled the roles of strategic nuclear bomber, aerial reconnaissance, and electronic-warfare aircraft in its various versions.
 Developed in the 1960s by General Dynamics, it first entered service in 1967 with the United States Air Force.
 The Royal Australian Air Force (RAAF) also ordered the type and began operating F-111Cs in 1973.
The PEGAZ 011 (Serbian: Пегаз ; "pegasus") is a medium-range tactical UAV for day and night attack (armed variant), reconnaissance and surveillance missions, target acquisition and designation that is being developed by Military Technical Institute in Serbia.
 Its flight autonomy is over 12 hours, and it sends data from the height of 3,000 m. Powered by a two-cylinder boxer type of engine with 32 kW (43 HP), it reaches the maximum flight speed of 200 km/h.
 The PEGAZ has a maximum weight of 230 kg, including about 40 kg of reconnaissance/surveillance equipment.
 It is 5.4 m long with a wingspan of 6.34 m.
 It takes off automatically from improvised runways and performs tasks along pre-programmed flight (optional: catapult).
 There are two hardpoints for optional air-to-surface missiles for attack variant.
The Martin/General Dynamics RB-57F Canberra is a specialized strategic reconnaissance aircraft developed in the 1960s for the United States Air Force by General Dynamics from the Martin B-57 Canberra tactical bomber, which itself was a license-built version of the English Electric Canberra.
 It was operationally assigned to the Air Weather Service for weather reconnaissance involving high-altitude atmospheric sampling and radiation detection in support of nuclear test monitoring, but four of the 21 modified aircraft performed solely as strategic reconnaissance platforms in Japan and Germany.
The General Dynamics F-16 Fighting Falcon is a single-engine supersonic multirole fighter aircraft originally developed by General Dynamics (now Lockheed Martin) for the United States Air Force (USAF).
 Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft.
 Over 4,500 aircraft have been built since production was approved in 1976.
 Although no longer being purchased by the U.S. Air Force, improved versions are still 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 General Dynamics F-111C (nicknamed "Pig") is a variant of the F-111 Aardvark medium-range interdictor and tactical strike aircraft, developed by General Dynamics to meet Australian requirements.
 The design was based on the F-111A model but included longer wings and strengthened undercarriage.
 The Australian government ordered 24 F-111Cs to equip the Royal Australian Air Force (RAAF) in 1963, but the aircraft were not delivered until 1973 because of long-running technical problems.
 During 1979 and 1980 four of these aircraft were converted to the RF-111C reconnaissance variant.
 Four ex-United States Air Force (USAF) F-111As were purchased by Australia and converted to F-111C standard in 1982 to replace F-111Cs destroyed during accidents.
 Australia also operated 15 F-111Gs between 1993 and 2007, mainly for conversion training.
 The RAAF retired its remaining F-111Cs in December 2010.
 In Australian military and aviation circles, the F-111 Aardvark was affectionately known as the "Pig", due to its long snout and terrain-following ability.
