CV-17 Shandong (002 carrier) Thread I ...News, Views and operations

There is still the trials at different load outs. It is safe to assume that the maiden trial of the Type 001A was conducted with an empty hangar with no aviation fuel or munitions stored. So future trials would have to be conducted with the ship carrying stimulated weights of standard and max loadouts.
Then there is the matter of propulsion reliability, that can be possibly tested by having the Type 001A making a trip to to the Hainan island base at flank speed and back again to test how well the engines hold up in various sea states outside that of Shandong.
Finally there is the general issue of seakeeping, testing how the ship rolls about in various sea states is especially important considering how huge the effects would be on a crowded hangar and flight deck, as well as the effects on the crew. Suffice to say, it would be impossible for the PLAN to find all the right conditions of sea states within just a month of voyage, and at all the different speeds and headings.
And these are just the basic requirements, if the PLAN desires to go the extra mile they can also conduct shock trials like the USN to see how well the systems hold out under a stimulated attack.
If what the chairman of the CSIC meant was that the Type 001A had just completed the basic trial of shaking down the various systems for the first time that is believable. But a full physical sea trial would entitle much more than that.
The articles were quite specific to make mention that the Type 001A had conducted ALL its sea trials, which is the ridiculous part.

Well I am pretty sure they did the power load test at 25% load, 50% load, As I understand they did run at full 100% power for 2 days
Remember that CV 17 system is almost identical to CV 16 So they already tested most of the system on CV16 It is not like they have to start from the scratch. So all those test that you listed have already been done on CV16. Because we know Varyag come with only propulsion system even that China claim to make additional changes to the propulsion and power plant to make it reliable
In engineering there the principle of precedent Sometime you don 't even have to do calculation if your system is duplicate of other system that work perfectly for a long time. It is proven already

Now structural integrity is something else, as this the first carrier that they built . But they have been building large war ship and commercial ships for decades. And simulation technology has advances so far I am pretty sure they have the confidence of structural integrity. Even in metallurgy they use simulation Technic Like how they fabricate rail line with undulation tolerance of 0.3 mm see that in min 13:09

BTW welcome JSCh Hope you will bring us all those fantastic photos that you posted on PakDEf

China's first domestically built aircraft carrier has reportedly completed all its first sea trials, with experts saying the result was satisfying and provided a good base for upcoming further trials on Thursday.

The sea trial results for the ship, known as the Type 001A, have been successful, revealed by China Shipbuilding Industry Corporation (CSIC) Chairman Hu Wenming said on Tuesday, according to the company's official website.

The carrier set off for first sea trials from the Dalian Shipyard in Northeast China's Liaoning Province on May 13 to test its power, drive, and electrical systems, including control and communications equipment.

The success marks that China has made a record by independently building a domestic aircraft carrier and finishing first sea trials in such a short time, Song Zhongping, a military expert and TV commentator, told the Global Times on Thursday.

It would take another six months to one year before the ship is delivered to the People's Liberation Army (PLA) Navy, Song said, while noting "we don't need to rush it because the more tests it takes now the better it performs later."

CSIC has also made major headway in manufacturing new equipment and applying new technologies, Hu was quoted as saying by the news site thepaper.cn on Wednesday.

The PLA used to lack air supremacy in the South China Sea and on the high seas, Song said, adding the aircraft carrier could overcome the shortage.

The ship is China's second aircraft carrier after the Liaoning, and its construction began in 2013, People's Daily website people.cn reported.

The aircraft carrier is a milestone that shifted PLA Navy's strategy from offshore to high seas, Song added, saying China would have three aircraft carrier fleets between 2020 to 2022 and possibly up to six in the future.

Pardon, ... but that cannot be!

The carrier just completed its first sea trails so said its maiden voyage. It was never ever tested so that all tests could have been completed.
There were no aircraft tests, surely no long distance cruise and so on.

Also how could this ship be delivered to the Navy already by year's end if not all tests were accomplished.
No carrier was ever delivered within such a short time after its first cruise.

IMO a very bad report put together from a writer who has barely a clue on that topic.

The drydock is basically full, 002 should be moved out and Liaoning moved in soon.

By the way ... wellcome here.

Sea trials cannot be cut short just because a similar ship was made or trialed earlier. There is just too much invested and at stake to make such a risky assumption, and risk a multi billion dollar asset going belly up. Moreover, the Type 001A contain incremental differences that can change the sea handling of the vessel significantly if found out.
And unless the 001A somehow managed to change it's loadout in the middle of the ocean without the proper equipment, there is no way it could have conducted different power load tests in a single voyage. And 2 days of full speed trials would not be enough to determine the reliability of the engines, IMO considering the Type 001A is expected to perform missions up and down the entire 1st island chain.
And the PLAN does not follow this thought either, each of the Type 052Ds are also put through their phases through lengthy trials . So there is no reason to think why it should be any different for the Type 001A.

That's the thing, these articles smack of pretty sloppy reporting and research. The fastest that we can expect would be the sea trials being completed at this year's end and the commissioning taking place early next.

Deino you don't appear to follow the US Military, so FYI there're some projects, called gamechangers

(the Fords, the Zumwalt-class destroyers, Littoral Combat Ships, F-35s),

which are grossly delayed and over budget (but are 'too big to fail' so won't get cancelled) and have dubious (sometimes laughable) performance;

what the Pentagon does is rushing them into service
