China’s muchdebated J20 stealth fighter has now entered the lowrate initial production (LRIP) phase. Following on from two prototype/technology demonstrators and at least six preproduction development aircraft, the first of a new batch of production examples made an appearance outside Chengdu’s works in late December. It reportedly made its first flight on January 18, by which time a second LRIP aircraft had also been spotted at the airfield.
Whereas the earlier aircraft had all been numbered in the 20xx range, and were revealed in a full painted finish, aircraft 2101 was seen undergoing taxi trials in December in a yellow primer finish typical of aircraft fresh from Chengdu’s production lines. A second LRIP machine, 2102, was recorded in January, also in the primer finish.
Designed by the 611 Institute and built by the Chengdu Aerospace Corporation at the Huangtianba airfield, the J20 is a large multirole fighter with stealthy features similar to those found in the American F22 and F35. Although very little is known about its intended purpose, the aircraft appears to offer capability in a number of roles, including longrange interception and precision attack.
In terms of weapon carriage the J20 has a similar arrangement to that of the Lockheed Martin F22, comprising two lateral bays for small airtoair missiles such as the agile, imaginginfrared PL10, and a large underfuselage bay for accommodating larger missiles and precisionguided surface attack weapons. The 607 Institute’s new PL15 activeradar missile is thought to be the primary longrange airtoair weapon, reportedly having been testfired from a Shenyang J16 platform last year. The PL21, a ramjetpowered weapon in the same class as the MBDA Meteor, is another possibility for the J20.
The sensor suite includes an electrooptical targeting system (EOTS) and a largearray AESA radar, which was developed by the 14th Institute at Nanjing Research Institute of Electronics Technology (NRIET, 14th Institute), and is possibly designated Type 1475/KLJ5. Diamondshaped windows around the fuselage suggest that a distributed aperture infrared vision system is installed.
In the cockpit, the J20 sports three large color displays, plus other small screens, and a holographic wideangle headup display. An advanced datalink has been developed, and a retractable refueling probe is located on the starboard side of the forward fuselage. Much of the avionics suite has been tested by the CFTE (China flight test establishment) aboard a modified Tupolev Tu204C, in much the same way as the systems of the F22 were tested in a Boeing 757.
One area that has dogged the J20 is the powerplant, where Chinese indigenous development has lagged behind that of the airframe and systems. The intended powerplant for the J20 is believed to be the WS15, an afterburning engine in the 44,000poundthrust (197kN) class 2/14/2016 Defence News, China's J20 Enters Production Defence News 3/5 being developed by Xian, and which may ultimately feature thrustvectoring. However, this engine is not expected to be ready until around 2020. In the meantime, the J20s produced so far have been powered by the NPO Saturn AL31FN (as used in the singleengine J10) imported from Russia. The latest J20s have the improved AL31FN Series 3 engine offering 30,800 pounds (137 kN) of thrust, but even this engine may not provide the J20 with “supercruise” capability.
J20 History:
Spurred on by developments in both indigenous technology and U.S. military capability, China initiated a project for a twinengine stealthy fighter in the early/mid1990s, subsequently reported by U.S. intelligence as the XXJ program. Chengdu/611 Institute’s Project 718 competed with a larger design from Shenyang/601 Institute, and was eventually selected in 2008.
Chengdu is believed to have built an initial batch of four prototype airframes, of which two took to the air. The first, 2001, made its maiden flight on January 11, 2011. It was followed on May 16, 2012 by aircraft 2002, which was subsequently renumbered as 2004. Two other airframes are understood to have been used for ground static and fatigue testing, and additional airframes may have later been produced for radar crosssection tests.
On March 1, 2014 the first of the development batch aircraft (2011) made its first flight. Whereas 2001 and 2002 appeared to be prototypes for evaluating aerodynamics and aircraft systems, as well as limited weapon carriage tests, aircraft 2011 was clearly outfitted for some mission systems.
Quite apart from the new RAM (radarabsorbent material) paint, there were numerous differences between it and its predecessors: the tailfins featured cropped tips; the inlets and DSI (diverterless supersonic intake) bulges had been redesigned; the leadingedge root extensions between wing and foreplanes were reshaped; the canopy had gained a stiffening bow frame; and the cumbersome mainwheel door design of the initial aircraft had been replaced by a much neater installation.
Perhaps the most obvious differences were the new nose design with a dielectric radome for an AESA radar featuring a sawtooth joint with the main fuselage, and the addition of an electrooptical targeting system in a fairing beneath the forward fuselage.
Three further development aircraft took to the air during 2014;Number 2012 on July 26; Number 2013 on November 29; and Number 2015 less than a month later on December 19. The latter two lacked a nosemounted airdata probe, suggesting that the AESA radar was installed. Aircraft Number 2016 flew on September 8, 2015 with reshaped DSI bulges and lengthened fairings around the nozzles to improve rearaspect radar crosssection. Other changes included enlarged fairings to either side of the engine nozzles. Aircraft 2017 followed on November 24, with a slightly more pronounced hump to the canopy.
At least four aircraft of the development batch were transferred to the CFTE (China flight test establishment) at XianYanliang for tests. It is expected that the initial LRIP aircraft will be dispatched to the Chinese air force’s test and training center at Cangzhou once initial manufacturer/acceptance trials have been completed, and during 2017 the first frontline regiment could start to receive aircraft. IOC is slated for 2019, but may occur earlier given the priority afforded to the J20 program. Chinese officials have stated that final requirements could be between 500 and 700 aircraft.

Let's remember this date...
Project 718 enters service (I hope it is true)...
Is there any information on what he is so sure ?? These images showing both 2013 & 2015 are quite old from last year (dated 17. February 2015) and the last one came up right after 2001's maiden flight in 2011.
So if 2101 has received a FTTC-serial or the other '201x-types were transferred to the FTTC, then o.k. ... but these images alone are IMO no proof.

It is like half-glass full/empty situation, I'd rather believe it is true. Let's wait 7 days as more news will come out usually.
