The Chengdu J-20 or Chengdudu J-20 (simplified Chinese: 歼二十; traditional Chinese: 殲二十; pinyin: Jiān èr shí; literally "Porcelain Annihilator") is a fifth generation stealth, twin-engine fighter aircraft prototype developed by Chengdu Aircraft Industry Group for the Chinese People's Liberation Army Air Force. In late 2010, the J-20 underwent high speedtaxiing tests. The J-20 made its first flight on 11 January 2011. General He Weirong, Deputy Commander of the People's Liberation Army Air Force said in November 2009 that he expected the J-20 to be operational in 2017–2019

The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, fifth generation multirole fighters under development to perform ground attack, reconnaissance, and air defense missions with stealth capability. The F-35 has three main models; one is a conventional takeoff and landing variant, the second is a short take off and vertical-landingvariant, and the third is a carrier -based variant.
The F-35 is descended from the X-35, the product of the Joint Strike Fighter (JSF) program. JSF development is being principally funded by the United States, with the United Kingdomand other partner governments providing additional funding. It is being designed and built by an aerospace industry team led by Lockheed Martin.The F-35 took its first flight on 15 December 2006.
The United States intends to buy a total of 2,443 aircraft for an estimated US$323 billion, making it the most expensive defense program ever. The United States Air Force (USAF) budget data in 2010, along with other sources, projects the F-35 to have a flyaway cost that ranges between US$89 million and US$200 million over the planned production of F-35s, depending on the variant. Cost estimates have risen to $382 billion for 2,443 aircraft, at an average of $92 million each. However, rising program cost estimates have cast doubt on the actual number to be produced for the U.S. In January 2011 Defense Secretary Robert Gates expressed the Pentagon's frustration with the skyrocketing costs of the F-35 program when he said "The culture of endless money that has taken hold must be replaced by a culture of restraint." Focusing his attention on the troubled VTOL F-35B Gates ordered "a two-year probation", saying it "should be canceled" if corrections are unsuccessful. Private analysts say the whole F-35 program is becoming a money pit. "The incredibly unfortunate phrase 'too big to fail' applies to this aircraft more than any other defense program", said Richard Aboulafia, an aerospace industry analyst with the Teal Group.

The Lockheed Martin/Boeing F-22 Raptor is a single-seat, twin-engine fifth-generation supermaneuverable fighter aircraft that uses stealth technology. It was designed primarily as anair superiority fighter, but has additional capabilities that include ground attack, electronic warfare, and signals intelligence roles. Lockheed Martin Aeronautics is the prime contractor and is responsible for the majority of the airframe, weapon systems and final assembly of the F-22. Program partner Boeing Defense, Space & Security provides the wings, aft fuselage, avionics integration, and all of the pilot and maintenance training systems.
The aircraft was variously designated F-22 and F/A-22 during the years prior to formally entering USAF service in December 2005 as the F-22A. Despite a protracted and costly development period, the United States Air Force considers the F-22 a critical component for the future of US tactical air power, and claims that the aircraft is unmatched by any known or projected fighter, while Lockheed Martin claims that the Raptor's combination of stealth, speed, agility, precision and situational awareness, combined with air-to-air and air-to-ground combat capabilities, makes it the best overall fighter in the world today. Air Chief Marshal Angus Houston, Chief of the Australian Defence Force, said in 2004 that the "F-22 will be the most outstanding fighter plane ever built."
The high cost of the aircraft, a lack of clear air-to-air combat missions because of delays in the Russian and Chinese fifth generation fighter programs, a US ban on Raptor exports, and the ongoing development of the supposedly cheaper and more versatile F-35 resulted in calls to end F-22 production. In April 2009 the US Department of Defense proposed to cease placing new orders, subject to Congressional approval, for a final procurement tally of 187 Raptors. The National Defense Authorization Act for Fiscal Year 2010 was signed into law in October 2009 without funding for further F-22 production.
