J-18 Red Eagle VSTOL (Jianjiji-18 Fighter aircraft 18) / F-18

According to some sources the J-18 nomenclature is reportedly the "Snowy Owl" stealthy JSF-type aircraft. Details about the Chinese J-18 project are not yet known. Chinese authorities have not formally released informtion on these developments. The "J-18" might simply be the J-15 Chinese copy of the Su-33 that appeared in a naval paintjob around the same time the J-18 rumors surfaced.

Under the Snowy Owl nomenclature, China is said to be secretly developing a triplane-canard-configurated fighter that has a totally different layout than the J-20, CCTV was quoted by Hong Kong-based Sing Tao Daily as reporting. Some Chinese online military experts believe that the Snowy Owl fighter is currently being developed by the AVIC Shenyang Aircraft Corporation (SIC). Online information regarding the SIC says that it is manufacturing a new type of aircraft whose design uses triplane canard configuration, Chinese netizens reported. The aircraft has a fixed vertical wing, and the engine has rhomboidal nozzles, according to the CCTV report, adding that the design renders the aircraft lighter than most of the fourth generation fighters.

In April 2011 Phoenix Television, citing a story in the Asahi Shimbun newspaper, reported that the J-18 had completed a test flight at a field base in the Inner Mongolia Autonomous Region. It was reported that the wings of the jet, similar to Russia's Su-33, a carrier-based multi-role fighter, could be folded so it would be deployed on China's future aircraft carrier.

Writing in Defense News, Wendell Minnick reported on 22 April 2011 that "China may have test-flown the J-18 Red Eagle vertical short takeoff and landing (VSTOL) fighter earlier this month, if chatter on Chinese-language military blogs is accurate.... Tests were supposedly conducted earlier this month and the fighter is similar to the Sukhoi Su-33 carrier-based fighter."

Richard Fisher, vice president of the Washington-based International Assessment and Strategy Center, said that "In 2005, a Chinese aviation industry source told me the Chengdu Aircraft Corporation was considering a F-35B-like program... Given the PLA's naval power projection ambitions, it is probable there is VSTOL or STOVL [short takeoff and vertical landing] fighter program. ... There are "many alleged programs in the Chinese blogosphere."

Chinese forums reported on 25 April 2011 that Beijing had probably began testing new J-18 Red Eagle short takeoff and vertical landing fighter aircraft. Officially the launching of test planes was not confirmed. Presumably, the J-18 flight tests took place in early April 2011. Flights were performed by an aircraft that was apparently similar to the Russian Su-33 carrier fighter. Why witnesses felt that the plane was the J-18 was not specified.

It is unclear why the Chinese navy would need a vertical-landing fighter, given the performance limitations associated with such designs, and considering China's apparent plans to deploy a big-deck carrier that would not need such a "jump jet."

The claim that the J-18 is 'similar to the Russian Su-33 carrier-based fighter' seems unlikely. If the plane had been copied from Sukhoi Su-33, for short take-off and vertical landing, Chinese engineers would have a lot of work on their hands. The Su-33 is a very large airplane, weighing 66,000 pounds fully loaded, which is three times larger than the the Anglo-American AV-8 Harrier jump jet. For comparison, other plane with a vertical takeoff and landing capabilities includ the the Soviet Yakovlev Yak-141, which weighs 19.5 tons, and the American F-35B, which weighs 22.5 tons.

The creation of a heavy fighter with short take-off and vertical landing is possible, but the technical feasibility and economic viability of such aircraft remain unclear. The American F-35B Lightning II with short takeoff and vertical landing fighter aircraft has experienced a lot of technical difficulties, which threatened the program with cancellation. Among the identified problems-overheating engines mode vertical takeoff and landing, excessive weight fighter, problems with some components of vertical landing and failures in the software. Any such aircraft would require innovative technical solutions, and short takeoff and vertical landing requires significantly more fuel than a conventional deck fighter. The design of the chassis and engines of an aircraft of this type are particularly challenging.

Flight Internation reported in early 2013 about poor quality images alledgedly depicting a new Chinese STOVL aircraft that had recently appeared in several Chinese websites. The pictures show a twin engined aircraft (or flying model) with high-mounted canard wings and canted twin tails which may suggest that it is the Shenyang J-18, a new aircraft said to be in the same class as the Lockheed Martin F-35B Lightning II STOVL aircraft. Shenyang, the manufacturer of J-31 stealth fighter, which resembles the F-35 Lightning II, has been reportedly using RC models to test designs in flight, such as the F-60 model unveiled in September 2011 that preceeded the J-31. The pictures may be a scale representation of an on-going project.

The J-18 would be the countrys third stealth fighter prototype after the Chengdu J-20 Black Eagle and Shenyang J-31 Gyrfalcon. The development of the J-18 was first reported by Tokyo-based Asahi Shimbun in 2011, which revealed that the plane had already completed its test flight at a secret base in Inner Mongolia. Defense News, based in Washington DC, said this 4.5-generation fighter designed by Chinas Shenyang Aircraft Corporation is nicknamed Red Eagle. According to the Janes International Defense Review magazine, the J-18 has mounted with two vector jet engines for horizontal thrust, though it is still unknown whether this new fighter adopts the lift style of the US F-35 Lightning II or Russian Yak-141 Freestyle.

The Chinese military press reported out in mid-2015 on the announcement of a contractual agreement between two major Chinese aviation industry entities to partner on the so-called short takeoff project.

The editor of the Chinese magazine Aerospace Knowledge led off a mid-2015 issue with some thoughts on a Chinese STOVL aircraft. He first discussed the Chinese aircraft carrier Liaonings relatively small fighter complement and suggested that future iterations will not exceed 50 fighters, but those numbers will not afford China the requisite firepower. He brings up the Falklands case, moreover, and notes that Great Britains force of Harriers prevailed even though the US Navy allegedly predicted at the time that Royal Navy airpower was too weak. While professing no special knowledge about whether the J-18 type [fighter] . . . exists or not, he suggests that the urgency is high for Chinese naval aviation and the outlook bright for a Chinese STOVL fighter, concluding: . . . perhaps in the near future, we will get some really good news."

Another article, in China Defense News, did not mention the J-18 by name, but appeared in this official military newspaper under the headline How Will China Develop a Short Takeoff Fighter? This article made several interesting assertions, including that China had been working on V/STOL technology since the 1960s and that Beijing apparently acquired a Russian V/STOL Yak-141 prototype fighter to tinker with and study back in 1994. This analysis concluded that V/STOL fighters flying off of amphibious attack ships are the logical choice for any navys second line of defense (behind the big decks).
