In its first report to Congress on China's military capability since the first flight of the J-20, the Pentagon says it "does not expect the J-20 to achieve an effective operational capability prior to 2018."That does not mean the U.S. Defense Department shrugs off the development entirely. "The appearance of this prototype underscores the level of [Chinese] investment in advanced defense systems," the report states.The Pentagon sees "several hurdles" before the J-20 enters production, but names only one challenge: "the mastery of high-performance jet engine production."In many respects the J-20 timeline is impressive, though, especially compared to the Pentagon's own development timelines or that of other western programs. If you assume the J-20 is merely an early prototype, achieving an in-service capability within seven years is much faster than anything the Pentagon could deliver. The F-22's prototype, the YF-22, first flew in 1990, but the system was not fielded until 2005. If the Pentagon's J-20 projection holds, the Chinese program also would beat the U.S. Air Force program even if you use the 1997 F-22 first flight date.The Eurofighter Typhoon is another example: first flight (of DA1) in 1994; Italy declares initial operational capability in 2005, the first operator to do so. The story for Rafale is no different.The real race is on between the J-20 and the Russian T-50 (PAK-FA). The T-50 first flew in early 2010 and Russia wants the system to be fielded in 2014.
