“Military Parity”.
Canadian Journal of China Defense Review published an article in which he said that China supplied the Russian Su-35 will receive the designation Su-35K (“Kitay (China)”), news.wenweipo.com May 5.

The article said that China is pointless to buy these fighters without weapons, especially missiles of “air-to-air” and “air-to-surface”. These missiles can top to perspective arsenal other Chinese fighter particularly, J-11B, J-15, J-16 and others.

su35-armaments.jpg


China Defense Review Magazine (Canada) has published an article saying that the Su-35 fighter that Russia sold to China will be named Su-35K (K word meaning "Kitaisky", ie China).

The article said that is meaningless for China if the fighter does not buy weapons, especially missiles, air-to-air and air-to-face. The future missiles may complement the arsenal of other Chinese fighter J-11B, J-15, J-16 ...

First of all, China should learn the real features ("performance") of Irbis-E radar antenna on the passive phased Su-35. Believe this radar capable of detecting targets with effective scattering surface at a distance of 3 m2 to 350-400 km, 30-cling target and target shoot 8 of them.

Su-35 advanced arsenal of powerful, including improved anti-ship missile Kh-31AD with jet engines new straight line, has a range of 250 km.

Russia has also developed anti-radar missile Kh-58UShKE new generation has a range of 200 km. The missile can also be used to equip the stealth fighter 5 generations of Russians.

Anti-ship missile Kh-35UE new generation has a range of up to 260 km. The missile is equipped with active radar lead investor.

Tactical missile Kh-controlled 59M2E been developed on the basis of Kh-59ME with a range of 115 km (Kh-59ME is equipped with the Air Force in China).

Kh-59М2E different variations in that the basis of the conduction system features higher in low light conditions, with the ability to destroy targets at night. Russia has developed the Su-59MK2 Kh-35 missiles with warheads weighing 320 kg explosions (cluster warhead weighing 283 kg). Maximum range of the Kh-35MK2 is 285 km.

Russia has developed the Su-35 is not a rocket they fight. To-air missiles RVV-BD long-range (R-37) is upgraded variant of the R-33 missile is equipped interceptor MiG-31. R-37 has a range of up to 200 km. The missile can destroy fighter with overload to 8g, as well as bombers and aircraft commander / alarm early.

The missiles short range RVV-MD is mounted to the free end led 2 mode, the laser fuze assembly fight. The missile has a maximum range, destroy target elevation from 20-20000 m. RVV-MD weighing 106 kg, 8 kg of combat.

Medium-range RVV-SD is equipped with active lead investor radar, capable of leading independent missile during the terminal phase at a distance of 25 km from the target. The missile weighs 190 kg, weight of 22.5 kg fighting, a maximum range of 110 km.

J-11B: Sukhoi made ​​in China

100% domestic Fighter

Success in the assembly of J-11 Chinese were thought to promote an improved variant called variant J-11B and J-11BS 2-seater with the components "100% local content."

In mid-2002, SAC unveiled its intention to build an upgraded multirole version of the J-11 by revealing a mock-up aircraft carrying various types of air-to-air and air-to-surface missiles. Russian sources also confirmed that SAC was pursuing a multirole variant of the J-11 designated J-11B with much greater Chinese-made content. At least three examples (#523, #524, and #525) of the J-11B have been delivered to the China Flight Test Establishment (CFTE) for flight test and evaluation since 2006. The aircraft was based on the Su-27SK/J-11 airframe, but with the following modifications:

An indigenous multifunctional pulse-Doppler fire-control radar reportedly capable of tracking 6~8 targets and engaging 4 of them simultaneously;
An indigenous digital flight-control system;
A Chinese copy of the Russian OEPS-27 electro-optic search and tracking system;
A strapdown INS/GPS navigation system;
A ‘glass’ cockpit featuring four colour multifunctional displays (MFD) and a wide-angle holographic head-up display (HUD);

The aircraft could carry the Chinese-made PL-8 IR-homing SRAAM and PL-12 active radar-homing MRAAM for air-to-air combat. While the PLAAF currently has the capability for two-target engagement using the Su-27/-30 and R-77 (AA-12 Adder) combination, successful integration of the PL-12 on the J-11B would likely provide a genuine multi-target engagement capability. The J-11B is also expected to have enhanced air-to-surface attack capabilities with the indigenous precision strike ammunitions such as LT-2 laser-guided bomb, the LS-6 precision-guided glide bomb, the YJ-91 (Kh-31P) anti-radiation missile, and the KD-88 air-to-surface missile.

During the 6th Zhuhai Air Show held between 31 October and 5 November 2006, China revealed first official details about the indigenously developed FWS-10A ‘TaiHang’ turbofan engine. The engine had already been successfully tested on a modified Su-27K fighter and possibly on some J-11 airframes too. The engine is understood to be similar to the Russian Lyulka-Saturn AL-31F turbofan engine in both technology and performance. However, it is unclear whether the FWS-10A has already been fitted on the 'indigenised' variant of the J-11.

Boeing F-15SE Silent Eagle

F-15SE-Silent-Eagle.jpg


F-15SE Silent Eagle is an upgraded version of the F-15 Strike Eagle aircraft, being developed by Boeing for international customers. The F-15SE features an innovative design which reduces its radar cross section. A prototype of the F-15SE Silent Eagle aircraft was first unveiled in March 2009. The F-15SE flight demonstrator aircraft, F-15E1, completed its maiden flight in July 2010.
F-15SE Silent Eagle design
"The F-15SE flight demonstrator aircraft, F-15E1, completed its maiden flight in July 2010."

F-15SE is 63.6ft (19.4m) long, 18.5ft (5.6m) high and has a wingspan of 42.8ft (13m). The basic design of the F-15SE is similar to that of the F-15 Strike Eagle aircraft with new components added. The new components include the conformal weapons bay (CWB) instead of the standard conformal fuel tanks.

The CWB significantly increases the internal carriage capacity of the aircraft and also reduces its radar signature. Two additional weapons stations have been included to enable the aircraft to carry an additional four air-to-air missiles.

The Silent Eagle also features twin vertical tails canted 15° outward. Canted tails provide rear lift to the aircraft and reduce ballast usage, while increasing the range by 75 to 100 nautical miles. Coatings will also be applied to various areas of the aircraft to minimise the radar signature.

The F-15SE has also been designed to function as a non-stealthy, multirole aircraft. The CWBs can be removed and the aircraft can be reconfigured to include conformal fuel tanks based on mission requirements.
F-15SE Silent Eagle development programme

Boeing commenced development of the F-15SE as an evolution to the F-15 family of aircraft. The company signed a Memorandum of Understanding with Korea Aerospace Industries in November 2010 for development of the F-15SE's CWB.

Boeing successfully completed the weapons launch from the left CWB of the F-15E1 flight demonstrator aircraft in November 2010. The F-15E1 launched an inert AIM-120 demonstrating the aircraft's ability to deploy a missile in flight.
"The F-15SE can carry air-to-air missiles, such as AIM-120 and AIM-9, and air-to-ground weapons."

Wind tunnel tests on the CWB of the Silent Eagle were completed in June 2012. A scale model of the aircraft was used to test aerodynamics of the CWB design.

Boeing has offered the aircraft for the F-X III competition launched by South Korea's Defense Acquisition and Procurement Agency to procure 60 new fighter aircraft for the Republic of Korea Air Force. The F-15SE is competing for the $7.3bn order with the Eurofighter Typhoon and Lockheed Martin's F-35.

The three companies submitted their formal bids in June 2012. South Korea was scheduled to decide the winner of the competition in October 2012 but the decision has now been postponed to mid-2013.

New orders from Saudi Arabia and Japan are also the driving forces behind the development of the next generation of F-15 aircraft. The development cost of F-15SE is estimated at $100m each. Boeing plans to offer the aircraft to five foreign customers with an estimated market for 190 orders. Flight testing of the F-15SE is expected to be carried out in 2013.
Aircraft engines, cockpit and avionics

The F-15SE will be fitted with two General Electric F110-GE-129 turbofan engines providing thrust of 29,000lbs or two Pratt & Whitney F 100-PW-229 engines providing thrust of 29,000lbs.

The F-15SE will feature next-generation Joint Helmet Mounted Cueing System produced by Vision Systems International, Elbit 11in x 19in Large Area Display (LAD) system on the front and rear cockpits, digital fly-by-wire flight control system, Link-16 Fighter Data Link and infrared search and track (IRST) system.

An advanced targeting pod provides the aircraft with target identification and autonomous tracking capabilities. A navigation pod will also be fitted to the aircraft providing it with all-weather and night-attack capabilities.

The aircraft will also feature advanced electronic equipment including BAE Systems digital electronic warfare system (DEWS) and active electronically scanned array (AESA) radar.
F-15SE weapons and performance

The F-15SE can carry air-to-air missiles, such as AIM-120 and AIM-9, and air-to-ground weapons including precision-guided weapons, JDAM and globules admire. The F-15SE can fly at a maximum speed of 2,655km/h. It can climb at the rate of 15,240m/min. The aircraft will have a range of 3,900km and a service ceiling of 18,200m. The empty weight of the aircraft will be 14,300kg and the maximum takeoff weight will be 36,741kg. The aircraft can carry a payload of 11,748kg.

Almost all four fighters are applied RAM technology, to reduce RCS. At BVR air combat, In 4 fighter, J-11B is the highest number RCS and ECM equipment such as sensors, jamming pod old (Russian type L-005 or KG-300G produced by China).

Su-35K was probably minimized down to the RCS of 10m2 down 3m2 (when not carrying weapons, as I read some sources also said that the Su-35S can be coated onto the RAM on missile), compensate for relatively large RCS than F-15SE, F/A-18 Block 3 (according to some predictions may lie in the lower range of 0.1 m2. While the F-15SE only as a variant F-15C / E with its internal weapons & RAM. F-15SE not redesign the airframe to fit as F-22/35 airframe ability to reduce RCS, F-15SE RCS can speculate coming down from 20m2 to below 10m2..) J-11B, Su-35K have better maneuverability than the F-15SE and F/A-18 Block 3 while dogfight.

Along with Irbis-E PESA, Su-35K has radar range the farthest. But without the ability to change frequencies continuously as AESA radar (AN/APG-63V3, APG-79) of F-15SE and F/A-18 Block 3. In dogfight, the winner will probably have to split the two sides, Su-35K, J-11B is said to have better maneuverability, but the F-15SE, F/A-18 Block 3 will offset by this HMDS helmet integrated air combat, HMDS of Russia and China are said to be worse, Russia even Topsight to use HMD-I production by the French's Thales company.

Okay I see here comparisons to the newest of the eagles and hornets as well as a offered flanker but the eagle and hornets have reduced rcs features integral to the package.no evidence of that in the flanker or J11 that we know of. Although it is possible to reduce the rcs
In addition if you are attempting to compare fighters via generation and role you should probably add the Typhoon and rafale to the mix.

Aren't versus threads banned? The F-15SE, F/A-18E/F Block III, Su-35S, and J-11B all have their respective advantages and disadvantages.


The F-15SE has incredible amounts of radar cross section reduction, owing to its conformal weapons bays, canted vertical stabilizers, application of composite materials, and use of radar absorbent material. However, for all intents and purposes, this stealth is limited and is essentially negated when heavy external weapons are added; the same is true for all other aircraft. The F-15SE also has an upgraded AN/APG-82(V)1 AESA radar but not much is known about it. It still uses the older F100 engines.


The F/A-18E/F Block III is also a very stealthy aircraft owing to its canted vertical stabilizers, diamond intakes, composite materials, and radar absorbent materials, but, like the others, is susceptible to detection if loaded. It has a powerful AN/APG-79 AESA radar but again not much is known regarding it.


The Su-35S is not so stealthy, but it is a very kinematically capable plane with a powerful avionics component and situational awareness abilities. It has a very high thrust to weight ratio due to its 142 kN 117S engines as well as unprecedented maneuverability due to its TVC. Its rear facing radar provides additional search capabilities. Its Irbis-E radar is also very powerful, capable of having a search range of 400 km and can detect a 0.1 m^2 target at 90 km. It has a new cockpit which is different from older Flankers.


The J-11B is a combination of reduced radar cross section, upgraded engines, and an extremely powerful radar. It sports radar absorbent material which reduces its radar cross section by a factor of eight down to 3 m^2, composites that reduces its mass by 700 kg, and powerful engines. Its radar was developed by 607th institute, is the same radar found on the J-15 and J-16, and is able to track a 1 m^2 target from 450 km, 0.4 m^2 target from 280 km, and a 0.1 m^2 target from 250 km, partially owing to its 1760 T/R modules. It also features a new cockpit different from other Flankers.


In short, the F/A-18E/F Block III and F-15SE will possess a radar cross section reduction advantage over the J-11B and Su-35S. However, the Su-35S possess a huge kinematics advantage over the F/A-18E/F Block III, F-15SE, and J-11B. Additionally, the J-11B boasts a radar advantage over the F-15SE, F/A-18E/F Block III, and Su-35S.

Agree with most of what you said, apart from the last part. I wouldn't be so sure to claim that the J11B has a radar advantage over the other 3, especially the improved super hornet.

These planes are built and developed at different times, and are not really of the exact same generation for me. The american fighters are still under development and not yet fully operational while the J11B has been operational for a number of years now, and that's not taking into account the advantage in technology the US has over China.

I'd see the F-15SE, F/A-18E/F Block III and SU35S as '4++' generation, while the J11B only a '4+' generation fighter. For comparison, perhaps the rumoured J11D would match up better.

That's my opinion anyway.

That's my opinion anyway.

It's true that American aircraft are kept under wraps and are evolving programs, as is the J-11B, but again until we get a more detailed analysis of the AN/APG-82 and AN/APG-79, so far it seems that the J-11B's radar (I'll post sources later or you can check back on previous posts) has a range and detection advantage over the others. Of course that is not a completely accurate assessment since we don't have any solid information on US radars, but it's a guesstimate.

It seems like aircraft are commonly judged by how much external RCS reduction methods have been applied to it. That is not always wise though, since radar cross section reduction can only do so much given a legacy airframe and there are so much other factors that parlay into beyond visual range warfare. For example, the Su-35S clearly sacrifices some RCS reductions for kinematics advantage, and it seems that the J-11B just focused on avionics upgrades. So the J-11B, F-15SE, F/A-18E/F Block III, and Su-35S are in the same league, just with different specialized niches.

But it's agreed that it's best to wait for the J-10C and J-11D, or perhaps even the J-15 and J-16, for a fairer assessment, and that wait should not be long.

A point Sino the F/A18 blockIII has a external weapons pod that reduces its weapons cross section

Yes but the Hornet is nevertheless a classic airframe that was not designed with serious radar cross section reduction measures in mind. You can add all sorts of stuff to it but that is not going to make a significant difference in modern wars.

Accurate comparison between aircraft is a detailed affair even if you leave out the weapons carried. But are you considering active airframes or those under development? Of the SU-35, F-15SE, F/A-18 Advanced Hornet & J-11B, only the J-11B is in Military Service at the moment.

Russia earlier this year has ordered it's first 48 SU-35 to be inducted over the next few years. The RCS modified versions of F-15 & F/A-18 are still in development stage until funding / solid orders come along (F-35 being further along than either of the two).

So a comparison that includes the F-15SE & F/A-18 Advanced Hornet may as well include the J-20.

J20 might be stretching it abit... But yes, that's what I meant earlier, though comparable, it is definitely fairer to compare something that is under development with improved capabilities to the j11b such as the rumoured j11D model.

The J-11B is a morphing program and is constantly getting upgrades, so a comparison is pretty fair in this case.
