does that article say this female officer is in charge of the railgun project please?

any number(s) available? I mean the energy, muzzle velocity etc. announced

Specs seem to be classified at this time; the article has 80% garbage, then in the last two paragraph it hinted on the tests. I guess it is apparent enough for most people to read it that way LOL. The female officer is in charge of the railgun's energy storage that enables multiple discharges in short period of time.

China's railgun succeeded on the ship's tests due to the new hybrid energy storage technology research for rail gun, deputy researcher at PLA Navy Process Institute, Zhang Xiao.
レールガン用新型ハイブリッドエネルギー蓄積技術研究責任者、PLA海軍工程大学副研究員・張暁の報道による、中国のレールガンが艦上試験に成功した。

What they are saying is that they achieved breakthrough in energy storage technology

Dynex is one of the UK’s leading manufacturers of high-powered semiconductors, including insulated-gate bipolar transistors (IGBTs), which play an important role in energy conversion systems. Zhouzhou CRRC Times Electric bought Dynex for 8 million pounds.

China used the technology to manufacture its own IGBT chips for the first time. Times Electric built a £167 million manufacturing plant in Zhuzhou, Hunan province, modeled on the factory in Lincoln, according to a report in the China Daily. This produces £230m worth of semiconductors a year — and reports have emerged of high-powered IGBT devices being supplied to China’s military.

In November, the South China Morning Post in Hong Kong cited a military source who said China was “confident” of building electromagnetic catapults for its new aircraft carrier because of its ability to manufacture IGBT chips “developed by China’s first semiconductor manufacturer . . . Times Electric, and British subsidiary Dynex Semiconductor.

be designed for arduous pulse power conditions. Due to the inherent impedance of the power system and the power limits of current prime movers, it is impractical and unrealistic to draw a 160 MJ, 10 ms pulse of energy demanded by EM railguns directly from the ship’s generators. Instead, an intermediate charging circuit can be employed to draw and store energy provided by the GTA in an energy storage device (ESD) from the ship’s power system, prior to it being supplied to the EM railgun via a pulse-forming network.

The rate of fire can be increased to the required 10 rounds per min by increasing the size of the ESD from 160 MJ to 320 MJ, so as to limit the GTA load transients and maintain the QPS within STANAG 1008 limits.

Those are just some numbers pulled from a random paper, unrelated to the Chinese project.

I really hope they release a video eventually. Although the high speed camera is likely out of the budget of propaganda division?!

I also don't understand the complain on IGBT, it is not a secret. What the new chip fab did is to produce large amount of IGBT at a low cost, mostly for civilian use (high speed rail, boat...)

I add those article to give people of understanding what is the process involve in Rail gun firing to emphasize the need for energy storage and the importance of breakthrough

As usual they imply that China develop the rail gun with the help of western technology. Which is questionable Eventually China will figure out how to manufacture IGBT.
The IGBT purchase is more related to the high speed railway with the side benefit of speeding up the realization of rail gun

Anyway the success of rail gun is cause for celebration hopefully the will deploy it soon in real application
