PLAN Anti-ship/surface missiles

According to the description panel and the officers' presentation aboard the destroyer 167, the supersonic anti-ship missile YJ-12A has a range of "400 km" and has "several different ways of penetration". Its main targets are "fleets" and "aircraft carriers".

Thats huge AshM ... how many YJ-12A carried on the ship?

When did PLAN replace 16 YJ-83 with these monster?

Sorry for necroposting...

According to the text - which seems to have been removed recently by the Chinese manufacturer - new composite "sandwich" composite materials, created by an engineer called GONG Yuan Xun (宫 元勋) and his team, are used "very largely "in a certain project that has a high requirement in stealth, and that takes into consideration the" structural stealth "from the beginning of the design, in other words the geometrical / passive stealth.

The team had major difficulties in reconciling the mass, the thickness (of the hull?) And the need for broadband absorption. The obstacles that were eventually overcome in collaboration with the subcontracting factories to improve the training processes, and with the own laboratories of CASIC Institute No. 306.

The article also talks about two other competing institutions in another project for a stealth component, but no link can be established between the two projects mentioned here.

That seems to be some sort of meta-material.


Some meta-materials, in laboratory tests, have proven to have the capability to either absorb or transmit microwave frequency radiation. Their main issues typically are cost of manufacture, poor durability, or narrow spectrum stealth capabilities.

With regards to the YJ-12A it seems to be a major leap in anti-shipping capabilities for the PLAN. Judging by the looks of it this is some sort of ducted ramjet rocket missile. Which means it should be both supersonic and long range. The missiles are also huge so one has to wonder at the payload or the fuel type.

YJ-12 is a ramjet missile with an integral booster. For surface launch there is another booster on the tail that's disposed off. Integral booster means the ramjet chamber is filled with rocket propellant, making it a rocket engine at first. As the rocket fuel is consumed, it clears the chamber, which when empty, the intakes open to allow air in for true ramjet propulsion. By then the missile reaches its operating speed where there is sufficient air speed to ram and compress the air in. Payload is said to be about 200kg warhead for the YJ-12 and 250kg for its export version the CM-302. Range is adjusted by speed --- the faster a ramjet goes, the more efficient it is. It does require however, an optimum operating altitude that can make it vulnerable to detection and interception to achieve the longest range. If made to travel at low level in mid phase, the supersonic speed would need to be lower, fuel consumption can be higher and range would be lower, but detection can be less. At terminal stage, it decreases altitude to sea level and sprints in its final leg.

This differs in principal with the YJ-18 which is important to compare. The YJ-18, after a solid rocket booster lifting it off, consists of a cruising turbofan section at the rear, with a solid rocket at the front. After take off the missile goes into a low level subsonic cruise using its turbofan, flying low to avoid being detected. At the terminal stage, the turbofan section breaks off, the rocket takes over, which accelerates to a supersonic speed at sea level. Its basically a subsonic cruise missile with a supersonic final stage.

Just from the way they operate, both missiles have advantages and disadvantages over the other. Going to Point A to B, the YJ-12 will undoubtedly be faster. However, the YJ-18 might be more difficult to intercept during its midphase flight, and can achieve a longer range on a low to low flight profile, as the turbofan is more fuel efficient at lower speeds. Both appear to be huge missiles and both conduct evasive maneuvers at the final stage. Why the PLAN keeps both types of missiles I am not sure.

The Russians also have both the Kalibr (turbojet with rocket on terminal strike) and the Oniks (ramjet). I guess it depends on the target type. If time of flight matters you use the Oniks. Otherwise you use the Kalibr. I wonder about the cost of each though.

Could it be launched by type 052d & type 055 from it's UVLS.

We have not seen a VLS version of it, nor such a version is confirmed publicly, like through an actual firing act that the PLA would post on the media.

Its likely this idea is nixed, not because there is a technological reason for it, but because they don't see any need for it, with the YJ-18 filling this role instead.

The YJ-12 doesn't have a 500 kg warhead?

I don't think its literally a 500kg warhead, just figuratively, 500kg is the equivalent of a physical 200kg warhead hitting a target at supersonic speeds. The compression at impact plus the shockwave will do that for you.
