Dick Fisher's raison d'etre is the non-stop propagation of the Yellow Peril. His articles exhibit the characteristic fear/loathing/contempt/scaremongering that is typical of these journalists. His articles almost invariably end with the US military had better buy this, develop that, or else the Chinese will rape your women and eat your children. He is probably a paid shill for the American military industrial complex.

China claims breakthrough in electromagnetic launch system for aircraft carrier

China has reportedly achieved a breakthrough on a conventional propulsion system for its next carrier, which would allow it to operate advanced catapults for launching aircraft without necessitating the use of nuclear propulsion.

Hong Kong’s South China Morning Post newspaper, quoting sources close to China’s People’s Liberation Army, reported that a team led by China’s top naval engineer, Rear Adm. Ma Weiming, has developed a medium-voltage, direct-current transmission network to replace an earlier system based on alternating current.

Forming part of an integrated propulsion system, the new system would allow a conventionally powered aircraft carrier to operate an Electromagnetic Aircraft Launch System, or EMALS, which conveys a number of advantages over traditional steam catapults that include increased efficiency, precision and shortening aircraft launch cycles.

The source also said the Central Military Commission, chaired by President Xi Jinping, had wanted China’s next aircraft carrier to be fitted with EMALS, but designers had up to now been stymied by the power requirements of the system and whether a non-nuclear-powered ship will be able to generate enough power to operate it.

With this breakthrough, China will now be able to proceed with plans to build its third aircraft carrier, which is expected to be in the 80,000-ton range and capable of carrying a more well-rounded air group if it is fitted with catapults as planned.

The People’s Liberation Army Navy, or PLAN, has been operating a pair of catapults at its carrier training base at Huangdicun since the second half of 2016. The pair are believed to consist of a single steam catapult and one EMALS. The service is evaluating both systems and carrying out test launches using a modified Shenyang J-15 (Flying Shark) carrierborne fighter jet.

The PLAN currently has one aircraft carrier — the Liaoning, which is a refurbished and modernized Soviet-era Kuznetsov-class carrier — in service with another, locally built ship currently fitting out. The latter ship is a slightly modified version of the Liaoning, and both are equipped with a ski jump, which is used to launch the J-15.

However, the use of ski jumps places operational limitations to the PLAN’s carriers, as they are unable to launch larger and heavier aircraft like the U.S. Navy’s E-2 Hawkeye airborne early warning aircraft or the C-2 Greyhound carrier on-board delivery aircraft. The PLAN currently operates a version of the Changhe Z-18 transport helicopter fitted with a multimode active electronically scanned array radar on board the Liaoning as its airborne early warning platform.

However, compared to a fixed-wing turboprop aircraft like the Hawkeye, a helicopter has significantly reduced endurance and operating altitude, which results in a significantly reduced time on station and radar range, respectively.

The new power-generating system could allow PLAN warships to be armed with modern weapons like electromagnetic rail guns and directed-energy weapons. In March, Ma had told state broadcaster CCTV that the “ultimate aim” of his work on the integrated propulsion system was to “solve the problem of deploying high-energy weapons” from its ships.

He has also subsequently claimed that China’s EMALS technology was more advanced and more reliable than the system used on the U.S. Navy’s aircraft carrier Gerald R. Ford. The Ford marked its first aircraft launches using EMALS during post-commissioning trials in July.

Its development in the U.S. Navy has, however, been beset with problems, particularly concerning reliability while testing modifications of EMALS, which are meant to allow it to launch the Boeing F/A-18E/F Super Hornet and EA-18G Growler while carrying external fuel tanks.

There are two topics/issues in this article
1. The miss-conception of Nuclear power is prerequisite of EMALS
The prerequisite of nuclear power plant for application of EMALS was always a miss-conception and miss-understanding of underplaying technology. The living proof of that is the planned (but abandoned) EMALS on QE class.

BTW, QE's failure of adopting EMALS is not because conventional power plant does not work, it is because UK could not and still can not make AC IEPS (1st generation in Ma Weiming's word) work with EMALS. But China went straight to DC IEPS (2nd/3rd gen depending on who is talking) which natively superior than AC based IEPS in coping with huge load change.

2. The Chinese breakthrough
The article got this right. The breakthrough is that Ma made DC IEPS, he did something the British could not do for their QE, and will not be able to do in the next 5 to 10 years, so as USN.

If British choose Chinese path from the beginning (20 years ago?), they would have made the breakthrough.

It might have been better but probably also more expensive and also less certain. UK is really a poor country. Look at its National Health Service as just one instance.

The AC path is easier to start 20 years ago. Ma Weiming's first experiment was AC. Due to two reasons Ma decided to go straight to DC path. 1. The inherent shortcomings of AC. 2. China's lack of choice of good GT and diesel primo (primary mover) which was not a problem for UK. Some times, a blessing is a curse. Because of China's shortcoming, China was forced to go the better future proof path. DC path is more technically challenging in other aspect such as short-circuit protection, but China is at equal footing in this area as UK back then. So Ma took the right path, picked the challenge 10 years earlier than UK and makes it work today. Cost is less of a challenge than technology. It is another example of "弯道超车,后发优势", overtaking at curve, late-comer's advantage.

Double like. Same as for your post it at 1674
It is good to hear of a first rather than China just steals or copy ideas.

Thanks for the like. I spent some time to fresh up my college study and dug around recently to try to understand what Ma's achievement is and why. And I found even more 1st which are overlooked due to they are within the IEPS itself. One thing in a paper by Ma's student is the mentioning of SiC application in Ma's IEPS. It means SiC is either used or very close to be used. China would be the first (or equal firsts) to do so.

Indeed, this is a first in the world of major achievement by Chinese. Ma Weiming is going into the history for his great contribution when he dared to say China hold a 10 years lead of other major players. And this is not the only first as we know, quantum communication is another one, and more will come.

~ Thats great. I recently read that the uS. wants to have talks with Russia and China because they are worried about the spread Of hypersonic technology . Russia and China mast be I very close to the U.S. inthis technology , otherwise long all for discussions)

This is not correct. It is not the US government that is trying to initiate talks with Russia and China, it's a RAND report recommending that these 3 countries strike a hypersonic non-proliferation deal that resembles something like the MTCR.
