Self Propelled Gun/Rocket Launcher

A very interesting on using artificial intelligence to produce a new to improve the accuracy of laser guided projectiles. Two test fires using the new ballistic table enabled laser guided shells to hit bullseye from 16km away.

A machine translated version of the paper is attached to this post.

Abstract: In order to the large truncation errors and defects that cannot be solved quickly and accurately in solving the firing data of laser terminal guidance projectile by firing table, a method based on multi-model network is proposed to solve the firing data quickly and accurately. First of all, a six degree of freedom trajectory model of guided projectile is established, and the influence of the rear sight on the range in the initial conditions is deeply analyzed. Secondly, considering the influence of air temperature, air pressure, wind interference and other factors on the solution. The least square method is used to fit the air temperature and pressure, and the layer weight method is used to obtain the accurate ballistic wind, the elements as the input vector of the network model. Thirdly, samples are generated in batches, and deep neural network is applied to train each model in the network. Finally, the proposed method is verified by mathematical simulation and flight test. The simulation results show that the proposed method has a higher precision and an error rate of less than 0.2% compared with the traditional firing table.

Interesting article on possible 203mm tube artillery development:

Other than a possible conflict in the Korean peninsula, China would likely have little use for 203mm artillery.
It would not have enough range to fire at Taiwan from the mainland, and it would be hard to transport in case of attempt to invade Taiwan.
The Russians are trying to blow up Ukrainian fortifications built over the course of 8 years on the Donbass, the larger shells have better success at blowing those fortifications up, and the conflict is right next door. So things are different.

Lol is any of this even true:

The PLA’s recent announcement suggests a new effort to revisit this past ambition and move beyond its current 155mm artillery. Though the contract award provides little detail about the PLA’s intentions, it does offer intriguing clues. For example, the tests must include the firing of an 85kg projectile at about 920 meters per second. The Malka can reportedly fire a 110kg projectile at 960 meters per second, suggesting that Chinese guns may not yet be up to Russian standards. (Still, given China’s

If they want to judge barrel tech, even for guns of the same calibre, other factors that would be needed for judgement includes things like barrel weight, barrel life etc.

For these kind of articles always have a read of who the authors are to check what they've written before. This "quality" of analysis is about consistent with PW Singer's past track record.

This could well be a test of payload that just happens to be well suited to be shot out of a 203mm gun, given it's from PLASSF. There are maybe one or two institutes in China with 203mm tubes lying about that could be dug out of storage for this. I doubt it's for straight up developing a brand new heavy artillery.

For Taiwan, if the intention is to use heavy guns to take out entire buildings during urban combat (and for some reason you can't count on PLAAF to drop PGM for you) then it would be better to clone 2S4 Tyulpan and not Pion. The big mortars are even more destructive and the extra range of 203mm artillery isn't necessary for Taiwan.

this anti "himars" would be very convenient for the Russians.
