Is the Chengdu J-20 an F-22/YF-23/Mig-31 hybrid?

When I first saw the leaked images of the Chinese Chengdu J-20 a fifth generation stealth aircraft prototype developed by Chengdu Aircraft Industry Group for the People’s Liberation Army Air Force (PLAAF) I could not notice a resemblance to at least three other type of aircraft: the F-22 Raptor, currently operating with the USAF; the Northrop/McDonnell Douglas YF-23, a prototype fighter built in two examples that lost the contest to the Lockheed Martin F-22 for the USAF Advanced Tactical Fighter; and the the Mig-31 “Firefox”, a fictional aircraft appearing in “Firefox”, a 1982 action film produced and directed by, and starring, Clint Eastwood based on a 1977 novel written by Craig Thomas. Three aircraft: a contemporary one, a prototype and a fictional one, bringing us to some conclusions:

  1. The aircraft design is clearly inspired to the F-22
  2. The J-20 is sensibly larger than the F-22 and F-35
  3. The aft fuselage and nozzle geometry are not “stealth compliant” meaning that the authenticity of the photos is questionable (even though the aircraft could simply be a technology demonstrator or a very early prototype)

I’ll let you judge by yourself.

Actually, also the Russian Sukhoi T-50 (PA FAK) has many similarities with the J-20 as the following Sukhoi images show:

A few days ago, I published a post to explain how the F-35 JSF flies in both conventional and STOVL (Short Take Off Vertical Landing) Harrier-like mode. The following article provides some interesting info and images about the AV-8B, a version much similar to the one flown by the Marina Militare (Italian Navy):

The Harrier made its final flight with the British RAF last week, marking one end to the jet famous for being able to take off and land vertically. The jet’s recently declassified flight manual shows just how extraordinary it is.

Aircraft carriers with no aircraft…..

The following defense news article deserves a read:

RAF: Harrier Retirement Won’t Hurt F-35C Skills
Published: 17 Dec 2010 08:55
One of Britain’s senior Royal Air Force commanders has rebutted suggestions that retiring the Harrier GR9 will damage the ability to regenerate skills to operate the new F-35C variant of the Joint Strike Fighter off a new aircraft carrier when it enters service around 2020. “Anybody who thinks that operating a Harrier today was somehow going to link you with the F-35C on the Queen Elizabeth-class aircraft carrier is . It is just not true,” said Air Officer Commanding No. 1 Group Air Vice Marshal Greg Bagwell.
The Harrier is a short-takeoff-and-vertical-landing aircraft, while the F-35C is a conventional aircraft requiring catapults and arrestor wires to operate. The latter aircraft is destined to be used on the new 65,000-ton carriers now being built by a BAE Systems-led alliance. Britain originally intended to acquire the STOVL F-35B version of the Joint Strike Fighter, but as part of the strategic defense and security review in October opted to switch to the conventional F-35C variant. At the same time, the British government decided to immediately ax the joint RAF/Royal Navy Harrier GR9 force and decommission the aircraft carrier Ark Royal, leaving Britain without a maritime air strike capability until 2020, when the F-35C and the Queen Elizabeth-class warship are available. Britain’s joint force of 79 Royal Air Force and Royal Navy Harrier GR9’s aircraft took off into retirement Nov. 15 from their base at Cottesmore in eastern England and will now be scrapped, unless they can be sold or a new use for them is found. The Daily Telegraph newspaper said earlier this week the MoD was looking at a proposal to create a reserve squadron using the Harriers. The decision to decommission the Harrier and the Ark Royal has caused huge controversy, in part because its opponents say it will be difficult to regain the skills needed to run carrier strike operations in the future. Bagwell said he does not underestimate the challenges and risks involved in building the F-35C operation, but he thinks the RAF and the RN forces would have faced the issue regardless of whether the Harrier had stayed in service.
“The techniques and procedures to recover a conventional carrier aircraft using catapult launches and arrestor gear recoveries, or ‘cats and traps,’ are totally different from that of a STOVL aircraft,” he said. “That is just as true for the aircrew as it is for the ships crew. Whilst the Harrier would have preserved the requisite skill sets for the F35B STOVL variant of the Joint Combat Aircraft” – the name the British called their JSF program – “they are largely irrelevant to that needed to operate the F35C.
“Effectively, we need to build the skill sets for the new aircraft and carrier configuration from scratch. We all ready have plans in place to begin that build up over the next 10 years with our allies and partners.” He said it was a “tall order,” but regaining carrier skills is a problem Britain had previously faced and overcome. One senior Royal Navy commander agreed with Bagwell’s assessment and said there was a much bigger question mark over regaining deck skills than the capabilities of pilots Bagwell, who commands all of Britain’s fast jet operations, said the RAF and the RN “have 10 years to get our act in gear and understand what operating the F-35C variant means for training and other preparation. Some we will have to learn from the USA and France,” he said. The British already have a pilot exchange program with the U.S. with officers flying carrier operations with the F-18. Bagwell said he was confident British pilots would also be flying French Navy jets as well “We will be flying Rafales from French carriers within a few years. I’m sure of it,” he said.
The British are targeting the availability of a single squadron of F-35Cs by 2020 to equip a joint RAF/RN operation. Briefing reporters last week, Bagwell said that would require an initial order for about 40 aircraft. How the aircraft will be employed in the future has yet to be worked out, but said he thought the aircraft would not be tied to the aircraft carrier. “They are there to project air power. It’s irrelevant where they are launched from. The Royal Navy will hate me for this, but sometimes they will be launched from the deck of an aircraft carrier for good reason. Other times it will be in-country closer to the problem,” he said. Either way, he said the F-35C gave the British better deep penetration, ISTAR and other capabilities than the more limited STOVL F-35B.

Anything weird? Apparently, not. As Bagwell affirms, the Harrier could not contribute to generate the skills required to fly the F-35C since the conventional carrier variant has not a STOVL (Short Take Off Vertical Landing) capability. Right. Unfortunately, what must be underlined is that Britain had originally chosen the STOVL variant before the Strategic Defense and Security Review in October deciced to switch to the C variant making the Harrier GR9s APPARENTLY useless. It’s a matter of logic: the Harrier was not scrapped because of the C variant; the C variant was chosen because the Harrier was sacrificed (along with the Ark Royal aircraft carrier). With this decision, UK will not have aircraft to equip aircraft carriers until 2020. Since the development of the F-35 is taking more than expeceted in both terms of time and costs, was this the right pick? I don’t think so.

Is it Italy facing the same risk? Absolutely not. The current scenario offers just two options for the Italian Navy that can’t afford building a new catapult-equipped aircraft carrier in the short-mid period:

1) the F-35B is axed and the I GrupAer AV-8B+ will keep flying from the Cavour aircraft carrier until the aircraft lifetime expires

2) the Italian Harriers are replaced by the STOVL F-35B as soon as it becomes available.

How does the F-35 JSF fly and fight?

In May 2006, I wrote an article about my experience flying with the F-35 using the Lockheed Martin’s JSF Cockpit demonstrator. Since the article was written only in Italian and many foreign readers have been following my recent comments and articles about the F-35B, the Harrier and the STOVL debate, I thought it could be interesting for them to read it in English, especially because I describe also the way the aircraft flies and the way it transits from horizontal to vertical flight. I will also add the slide which were presented during the press briefing that preceeded the cockpit demo that I received from LM some weeks after my “flight”: even if they are some 5 years old, they provide an interesting look into some of the technologies introduced by the JSF.
Have a good read.

Today (May 9, 2006) I had the opportunity to travel in the future (even if it was a short-range trip, let’s say fifteen years ahead) as I attended an orientation session with the JSF cockpit demonstator. Under the supervision of a Lockheed Martin F-16 pilot, I virtually flew the F-35, a 5th generation highly advanced fighter which makes the so-called “sensor fusion” a reality and provides the pilot a stunning situational awareness, while still allowing for simple handling. The first feeling that I had when I was aboard the simulator, hosted by the Comando Squadra Aerea of the Aeronautica Militare (Italian Air Force, ItAF) at Centocelle, Rome, was that of being in front of a popular flight simulator from Digital Image Design: “Super EF-2000”. SEF2000 is a PC game that came out in 1997 and that I enjoyed a lot in 1998-99. The graphics for that time was excellent, the scenario’s complexity was good, the only flaw was the being too “easy”. It was basically a game and not a real flight simulator like Microsoft Flight Simulator or Falcon 4.0. The flight model was realistic but the plane was too easy to fly even for a newbie and the information provided by the avionics was too “user friendly”, rather different from those actually provided by aircraft of the 3rd generation. Well, I found the same easiness, the same “at a glance” symbology right in the JSF. The aircraft does not have a HUD (Head Up Display), but has one big touch screen that can be configured at will by tapping the screen with your fingers (like a PDA). The information normally presented to the pilot in the HUD are “projected” directly into the pilot’s helmet that is capable, through the sensors of the aircraft, to see in all directions through any surface. The pilot then has the impression of flying into the air (without an aircraft surrounding him) and can visually track the enemy aircraft with is sight not hampered by the tail or wing of his plane. Then, during a hypothetical dogfight the pilot is able to follow the enemy aircraft through the cockpit mounts, as if suspended in space. For the rest, as mentioned above, the symbolism is clear enough: the red triangles represent the enemies, the white are “unknown” and the greens are friendly aircraft. The JSF is able to share all its information via a network with the other elements of the flight or with AWACS and Rivet Joints. The menu can be browsed with a cursor moved by a small joystick located on the throttle. In short, everything pretty straightforward for someone like me, used to work at the computer; an experience somewhat “shocking” for those pilots who are accustomed to the analogue Starfighter-style cockpits. Obviously, with the JSF the pilot should focus on mission and information management, rather than worrying about “flying the aircraft”. By means of the DAS, the pilot can see all the electronic emissions on the 360 degress around the aircraft. He may even know the search and tracking frequency of the ground radar. Of particular interest was the opportunity to test the hovering capabilities of the aircraft, that is in fact also available in the STOVL version that interests both the Marina Militare (Italian Navy) and the Aeronautica Militare (Italian Air Force, ItAF). The pilot, by means of a switch manages the transition from conventional flight to the Harrier-style, so to speak. The aircraft autonomously directs the nozzle and reduces the speed to the IAS (Indicated Air Speed) previously set through a dedicated button on the throttle (which is also operated in automatic mode). Once in “vertical” mode, the aircraft is extremely simple to fly, even thanks to the camera underneath the fuselage that allows the pilot to see downwards, and to decide where to place the wheels. Moving the stick forward or backward the aircraft climbs or descends: with a couple of attempts, you can also manage to maintain the desired vertical speed. With the rudder, you can point the aircraft nose wherever you want and even a novice can land with some precision and without major problems. The only difficulty I encountered during the flight was distinguishing between all the switches on the throttle, that pushed up with the little finger, allowed me to select the autothrottle. As for the rest, airplane is a real dream, extremely easy to be piloted and able to provide the pilot with all the information he might need, in the preferred layout.

The above NOTAM has a particular historical value. It provides the route flown during the rehearsal and final flight of the last Harrier GR9s belonging to the Joint Force Harrier. In fact, on Dec. 15, 2010, Cottesmore airbase launched a 16 ship formation that overflew various RAF stations and local towns, which have been associated with the Harrier over the last four decades to bid farewell to the famous STOVL (Short Take Off Vertical Landing) aircraft. Beginning today, the STOVL concept is history for UK’s RAF and RN that were due to continue operating the Harrier until at least 2018, when the Joint Force was to have transitioned to Lockheed Martin’s F-35B. However, the iconic jump jet was decommissioned after 41 years of service as part of the Strategic Defence and Security Review (SDSR) to ensure the survival of a reduced number of Tornado GR.4s, a decision that, along with that of shifting to the carrier variant F-35C, was criticised by many because will leave UK without aircraft for its aircraft carriers, hence without maritime strike force, for at least a decade. The last flight on Dec. 15, was preceded by another historical flight on Nov. 24, 2010, when the HMS Ark Royal, the United Kingdom’s Flagship, facilitated the last ever launch of a Harrier GR9 from her deck at 09.00LT while sailing approximately 40 nautical miles off the coast of Newcastle. HMS Ark Royal is being decommissioned too under the SDSR with a considerable loss in British capabilities to project power and strike globally with an extremely versatile and flexible asset.

This is an excerpt from the RAF news release:

Harrier pilot Lieutenant Commander James Blackmore, the last pilot to ever launch a Harrier from the decks of HMS Ark Royal, said:
“This is a truly memorable day. We accept the decision to decommission both the Harrier and HMS Ark Royal; however, of course the final launch will be emotional. I have flown over 90 sorties off the Ship and combat sorties in Afghanistan, and the aircraft’s capability still astounds me. Landing an aircraft on a runway which is not in the same location as where you launched from gives exceptional flexibility.
I remember witnessing a Harrier in the hover when I was just 8 years old, since then I had wanted to do nothing else. I have flown Harriers for over 10 years, the training is complex and challenging but the added challenge and excitement of hovering a Harrier off the port side of HMS Ark Royal before landing vertically is an experience I will miss immensely.
I feel honoured and proud to be the last pilot to ever launch a Harrier jet from HMS Ark Royal.”
Deliberately keen to highlight the very Joint nature of Joint Force Harrier the last jet to recover in HMS Ark Royal was an 800 NAS jet piloted by a Royal Air Force officer, today the last jet to launch was a 1(Fighter) Squadron RAF jet piloted by a Royal Naval officer. Departing the Ship in one wave of four aircraft, the launch was led by Capt Mike Carty RM followed by: Lt Matt Fooks-Bale RN and Flt Lt Em Rickards before Lt Cdr James Blackmore’s historic final launch.
After the launch, the 4 aircraft conducted a 2 ship fly past, each squadron flying low past the port side of the Ship before conducting a final fighter exercise controlled by 849 NAS’ Seaking Mk7 helicopter, prior to returning to RAF Cottesmore.

Both the Harrier and HMS Ark Royal are due to leave the Service next year.
Reflecting on the Harrier and HMS Ark Royal, Captain Jerry Kyd, HMS Ark Royal’s Commanding Officer said:
“As the last Harriers lift off the deck of HMS Ark Royal for the final time it is with a real sense of pride that we remember the fantastic contribution they, and the carriers, have made to UK Defence around the world. The tremendous reception we received in Newcastle last weekend, where Ark Royal was built, reflects the very deep fondness for this iconic warship and her air group. Although we now look back on the significant achievements of the Harrier with immense pride and a tinge of sadness at our loss, we can now look forward to an exciting new chapter of Naval aviation as we continue the training for and procurement of the Joint Strike Fighter aircraft.
HMS Queen Elizabeth and her sister ship will enter service from 2015 and together with their helicopters and the Joint Strike Fighter, they will be a very powerful strategic asset able to project serious power anywhere in the world, delivering 21st Century Carrier Strike capability. Add to this the new Type 45 Destroyers, the forthcoming Type 26 frigate, the Astute class submarines and the Royal Marine Brigade, the United Kingdom will have a balanced Naval Service that remains in the premier league, working for Britain to deter potential threats, defend our global interests and, if necessary, defeat our enemies.”

The fate of the (+50) early retired Harriers is still unknown. Being perfectly airworthy and far from being too obsolete to serve in some air force, they might be cocooned or preserved until the time to be sold comes. Maybe some air forces could be interested in the aircraft, especially if we consider the uncertain future of the F-35B. Even if I think there are little chance that the B version of the F-35 will be canceled, those services that had planned to get their STOVL variant of the Lightning II as a Harrier replacement will look at the GR9s retired today with some interest.
