Chinese Missiles News & Discussions

CM-400AKG is a ballistic missile which employs a rocket engine, while YJ-12 is a cruise missile which employs a Ramjet engine.

That's the definition of a variant.

Variant means "not identical."

A family of missiles may share the same sensors or basic frame.

It does not mean they must have the exact same propulsion engine.
----------

Let me give you an example.

A Chinese J-11 is commonly referred to as a VARIANT of an Su-30. However, they only share the same basic airframe. The turbofan engines, WS-10A on the Chinese J-11 and AL-31 on the Russian Su-30, are completely different.

Similarly, there is no reason to expect the same engines on the YJ-12 and the CM-400AKG.
----------

The CM-302 closely resembled the YJ-12 in design. I think the CM-400AKG is the next-generation upgrade of the CM-302.

Come on. The Yj-12 and CM are so much different thy dont share the airframe nor the engine. The first is a true monster only able to be carried by the H-6G whereas the CM is a much smaller one able to be carried by the JF-17.
They share nothing. Not the size, not the mission profile, not the weight nor the propulsion system. They onky have the same colour maybe.

To say both are a variant of each other is as telling the J-16 a version of the JF-17.

That's your opinion.

There are reasons to think the CM-400AKG is the latest air-launched version of the YJ-12. The range, supersonic speed, and warhead specifications are all pretty close.


Never ever. Just look at their dimensions, their mission profile...
Since when is speed an item to tell it a variant?? All airliners have similar speed. An A.320 is roughly the same to a B-737 and no-one would call them variants.
Like I said. Only the colour is the same.

They are completely different in regards to engine, speed, flight altitude and path. Their developers are also different.

BTW logically both J-11 and Su-30 are Su-27 variants, but J-11 is not a Su-30 variant as J-11 is not rooted from Su-30 and the term variant implies a hierarchy.

YJ-12
range: 250km
speed: Mach 3.5
warhead: 205kg

CM400-AKG
range: 240km
speed: Mach 4 (because it is launched at a higher altitude)
warhead: 200kg

The two missiles look very similar in performance to me. I think Deagel and Missile Defense Advocacy Alliance are right. YJ-12 and CM400-AKG belong to the same family of missiles. Their performance characteristics are nearly identical.
----------

The analogy for a Boeing and Airbus airliner does not apply here.

The YJ-12 and CM400-AKG are both built by the same Chinese government.

Boeing is built by Americans. Airbus is built by Europeans.

If Boeing and Airbus airliners were both built by the same people then yes, they would belong to the same family of aircraft.
----------

A Chinese J-11 has completely different radar, fire control, weapon systems, and engines than a Russian Su-30. However, their performance characteristics are similar. Thus, a Chinese J-11 is commonly referred to as a VARIANT of a Russian Su-30 and classified as a branch of the tree.

Similarly, the performance characteristics of the YJ-12 and CM400-AKG are very similar. Since the YJ-12 came first, the CM400-AKG is commonly referred to as a VARIANT of the YJ-12. China has very few Mach 4 anti-ship cruise missiles. It is illogical to believe that China funded two separate expensive programs. Most likely, the CM400-AKG is a derivative of the YJ-12 project.

That doesn't change anything.



They apparently belong to different families of missiles.



These characteristics are unreliable.
You can believe whatever you want.

Send a letter to both Deagel and Missile Defense Advocacy Alliance and argue with them.

I don't care. I've simply explained the reasons that many people believe the CM400-AKG is a derivative of the YJ-12.

If you want to believe the Chinese government funded two completely separate Mach 4 missiles to achieve the same performance, that is your choice. I don't think the Chinese government was that stupid.
----------

The CM-302 was the first attempt to convert the YJ-12 into an air-launched cruise missile.

The CM400-AKG is a modernized version of the CM-302 after new design changes.

It is perfectly logical to believe the CM400-AKG is the next evolutionary design-upgrade of the CM-302. This would mean the CM400-AKG is still a derivative of the YJ-12.

The CM400-AKG did not pop out of thin air. It was probably based on experience gained from the CM-302. China improved the CM-302 by making design changes and designated the new missile as the CM400-AKG.

Does the CM400-AKG look different from the CM-302? Of course it does. China made as many improvements as possible. The most logical chain of events is that the Chinese engineers looked at the CM-302 and thought about ways to improve it. Thus, we have the CM400-AKG.

The CM400-AKG looks different, but it adheres closely to the original performance specifications for the YJ-12.

The nearly-identical performance specifications of the YJ-12 and CM400-AKG are not a coincidence.

YJ-12
range: 250km
speed: Mach 3.5
warhead: 205kg

CM400-AKG
range: 240km
speed: Mach 4 (because it is launched at a higher altitude)
warhead: 200kg

Sorry, but that's a lame argument.

So is the Chinese built A.320 and the COMAC built C919 then a variant ? Some stupid peoples would indeed think they are and some stupid peoples also think the J-10 is a Lavi-clone, the WS-10 is based on the AL-31 and so on.


Also I think Your data for the YJ-12 is wrong:

YJ-12:
Weight
2,500 kg (5,500 lb)
Length 6.3 m (21 ft)
Diameter 0.756 m (2.48 ft)
Warhead 205–500 kg (452–1,102 lb)
Engine integrated ramjet
Range 250–400 km (depending on altitude)
Speed Mach 2-4 (depending on altitude)
Guidance system INS/Beidou + terminal guidance

So that in comparison to Your data ..

CM400-AKG
Range
240km
Speed Mach 4 (because it is launched at a higher altitude)
Warhead 200kg

… both are no longer that similar. IMO it is more likely that DAEGEL is simply wrong in the same way Wiki post this BS. Nothing more.

Deino, you think the mainstream media is constantly wrong. You can believe whatever you want.

The mainstream media has experts with decades of experience. They are occasionally wrong about a minor detail, but they are mostly right.

You cannot just say: Oh look, the CM400-AKG doesn't look exactly like a YJ-12. Therefore the mainstream media is wrong.

The story is more complicated than that.

The CM400-AKG is most likely the successor to the CM-302. The timeline fits. Many years passed and the Chinese engineers upgraded the CM-302.

In any case, I grow tired of arguing with you guys. The mainstream media thinks the CM400-AKG is a derivative of the YJ-12. I think there are many reasons that the mainstream media is right, which I mentioned in my earlier posts. If you guys want to think the Chinese government is a complete idiot and wastes resources on duplicative efforts then that's your choice.

This matter is actually pretty easy to settle. Let's wait 5 to 10 years. Eventually, the designer(s) of the CM400-AKG will tell his story and we'll know for certain whether the CM400-AKG is a derivative of the YJ-12 or not.

The issue was raised that the CM400-AKG uses a solid rocket motor and the YJ-12 uses air-intakes. Thus, the claim was that the two missiles are completely related.

When you read the DEAGEL article, it specifically mentions the CM400-AKG uses a solid rocket motor. DEAGEL has already accounted for the CM400-AKG's solid rocket motor.

The distinction is not news.

CM-400AKG | Deagel

"The CM-400AKG is a smaller and lighter version of the YJ-12 anti-ship missile intended for use by tactical fighter aircraft such as the FC-1, J-10 and Su-30MKK/J-11. The supersonic CM-400AKG missile weighs 400 kg and has a maximum range of up to 100/250 kilometers and can fly at a top speed of Mach 4 carrying a 150/200 kg warhead. The missile is fitted with either a blast fragmentation or a penetration warhead to engage surface ships or fixed-position ground targets respectively. The missile can be fitted with an active radar seeker or an imaging infrared (IIR) seeker. The propulsion system uses a solid fuel rocket motor. The CM-400AKG anti-ship missile has been ordered by the Air Forces of Pakistan and China."

But engine is not ramjet, solid fuel rocket:p: and its not low flying cruise missile but high flying missile its a development of SY-400 rocket look at yourself
SY-400 / CM-400AKG
The 7th China International Aviation & Aerospace Exhibition was held on November 4th to 9th, 2008 in Zhuhai Airshow Centre, South China's Guangdong province. A new set of Chinese missile equipment, including the SY 400 rocket-powered guided missile weapon system, made its debut [Shen Ying, meaning Divine Eagle]. China is calling it as a guided artillery rocket system, hence claiming the 400 km range missile it is not limited by the 300 km range MTCR export restrictions. Capable of carrying an HE, fragment, submunition and EMP payload, other sources give this solid fueled SRBM an estimated range of 200km, well below the MTCR-mandated 300km restriction.

SY-400 system from the outset was designed as a tactic to-surface missiles, with a wing mainly used to increase the missile body lift, increasing the missile's gliding distance and improve range. The wing also plays a role in strengthening the the longitudinal strength, in order to avoid intense elastic oscillation.

SY-400 is not purely ballistic missiles since the end of the active segment, there is a very long flight distance, in this period of time, the missile had burn engine, the rudder has no gas for gas deflection, how the error correction produced during this time, only a control surface by air. The vane is only supporting the vertical launch system, gas in the vertical direction after the launch target deflection direction. So after the operation, will be discarded, after which control relis on the air rudder.

The main mix is based on a range, SY-400 for 180 km within the tactical support, as more tactical targets, so the use of smaller missiles, can attack several targets. The BP-12A is generally used for fire support battle, a maximum range of 300 kilometers, this is mainly because of the Missile Technology Control Regime restricting the export of missiles with a range of 300 kilometers.

Versatility has always been to improve national weapons development. For example, with 10 launch vehicles, as close to full support, these could have 80 SY-400, used for a remote support, can have 20 BP-12A, if the 10 private launch vehicles, that is, 5 vehicles SY-400, 5 BP-12A is the largest number of 40 SY400, 10 BP-12A, the task fell a lot of flexibility. SY-400 and BP-12A are using GPS / INS guidance, CEP of 30 meters, if the military code GPS system, or the military code of the Compass 2 system, and that accuracy can be further improved.

The CM-400AKG supersonic standoff missile was first on display at the 2012 Zhuhai Airshow as part of FC-1/JF-17's "complete" weapon package. Unlike most modern ASMs flying at the low altitude, the missile flies a rare high ballistic trajectory, powered by a solid rocket motor. It appears that CM-400AKG may have evolved from the earlier SY-400 SRBM. Therefore the effectiveness of such attack profile is still unknown.

The missile has a weight of 900kg, maximum range of 240 km, max speed Mach 5.5 (at diving stage?). It has INS during the mid-course and utilizes active radar/passive radar/IIR seeker with target-recognition capabilities at the terminal stage, which may improve its accuracy. The missile is claimed to be capable of terminal maneuver in some degree to avoid interception by SAM. CM-400AKG is speculated to have been designed to attack fixed or "slow moving", high value ground targets. It has yet to be confirmed that CM-400AGK is in service with PAF's JF-17.

CASIC builds all three anti-ship cruise missiles: YJ-12, CM-302, and CM400-AKG

China Aerospace Science & Industry Corporation (CASIC) is China's main missile designer and manufacturer.

Aviation Industry Corporation of China (AVIC) is involved in building military aircraft for China.

CASIC built the YJ-12, CM-302, and CM400-AKG anti-ship cruise missiles.

As I understand it, AVIC is responsible for the overseas marketing of CASIC missiles.

China spent years investing in the team that designed and built the YJ-12 anti-ship cruise missile. The YJ-12 has a variant called the CM-302.

Now, the CM400-AKG is China's latest air-launched supersonic cruise missile. There are only two scenarios.

Scenario #1: CASIC used the experienced team that designed the YJ-12 and CM-302 cruise missiles to design the new and improved CM400-AKG. This means the CM400-AKG is a variant of the YJ-12, because the same experienced design team made the modifications.

Scenario #2: CASIC picked a new team of greenhorns and somehow the inexperienced team managed to produce a superior CM400-AKG within only a few years and met the PLA requirements.

Obviously, Scenario #2 is far-fetched and Scenario #1 is the most likely. By using our common sense, the conclusion is that Deagel is right and the CM400-AKG is a variant of the YJ-12.

Civilian use of guided rocket SY-400 for typhoon research by penetrating a typhoon central and distributing drop sensors with satellite data link. Obviously with proper sensors/seekers and even data link it can hit any moving ship with a considerable size as every ship is slow moving target comparing to the rocket's speed.
