054/A FFG Thread II

^ Thanks

Is there a picture showing in full size this 054B ?

This one beside the 056, but can barely see the 1130 behind the scaffolding on the 056 from this view.

So far there is only one 054a (or b) with the 1130. The other 054a next to it is probably an earlier one with 730.

I don't think we should call it 054B btw, I think 054A block ii or something is more suitable.

There's already been a variation in models in the Type 054A programme and nowhere have I seen a Type 054B

A new gun does not warrant a new variant

Yeah the earlier visible variation is between a rounded flare bow edge (for the first 4 units?) vs the now more angular arrowhead like bow edge.

Well, once in a blue moon, Wantchinatimes gives you a corn kernel in the stuff they publish...

It's true. The Type 1130 CIWS has been installed on the 054 frigate. It probably should be called Type 054B in this case.

Here's an article about that Type 1130 CIWS.

China has developed a new close-in weapon system, or CIWS, called Type 1130, which has the firing power of 10,000 rounds per minute, portal Want China Times said, citing Russia media sources. The particular CIWS model, recently spotted being installed on a PLA Type 054A frigate, can reportedly destroy 90 percent of hypersonic missiles even travelling four times the speed of sound.

CIWS, a point-defense weapon, is used to detect and counter short-range incoming missiles as well as enemy aircraft. It is typically mounted on warships.

The Type 1130's Gatling-type gun, according to Want China Times, possess a 30 mm caliber. Its number of barrels were 11. Compared to its seven-barreled Type 730 predecessor, which only has one magazine of 250 rounds, Type 1130 carries two magazines. Each reportedly contains 640 rounds. The improved design and technology thus will enable China to fire more than 10,000 rounds per minute, with a chance of hit rate placed at 90 percent against Mach 4 missiles.

The massive CIWS has reportedly been installed on both sides of the Liaoning, China's first aircraft carrier. The Liaoning, which entered its second year of service with the People's Liberation Army Navy, even has a ski-jump ramp.

Citing Russian media, Want China Times said the Type 1130 CIWS will be deployed on the Type 055, the country's latest guided missile destroyer, very soon. It added theType 1130 CIWS will likely be placed on ships with a 12,000-ton displacement because of its gigantic size and weight, as well as the amount of electricity it will gobble up.

Early in 2014, reports flaunted that Russia was seeking to strengthen ties with China, following the annexation of Crimea. In fact, Russian President Vladimir Putin approved in March to sell S-400 Triumf to China. Sales of Russians arms don't get immediately approved, unless consented by the president himself. Apart from the S-400 Triumf, the two countries are also negotiating for the sale of the S-400 anti-aircraft weapon system and Sukhoi Su-35.

Moreover, China is fast tracking the completion of its aircraft carrier, a Type 001A, within just six years. The second domestic aircraft carrier, according to the Kanwa Defense Review magazine, will be fitted with four catapults and three escalators on board.

The article sorta contradicts the photo as it mentioned the 1130 will likely be placed on ships 12,000 tons due to weight and power requirements but the 054A is clearly less than that.

I think we can cut them some slack if they quote from reliable sources. But the statement

The Liaoning, which entered its second year of service with the People's Liberation Army Navy, even has a ski-jump ramp.

looks dumb.

Long time no fun speculation and wishful thinking posts.

So that was a badly drawn set of modifications over an 054a for possible successor variant. Main air search radar is put inside a protective cover, but basically it could still be a two sided rotating aesa, similar to Sampson only probably smaller and less powerful. Rear mast radar (x band as i remember) was removed and its functionality put into four fixed arrays on the main mast, just under the top radome. Whole main mast was moved slightly forward and the gun targeting radar put on a protrusion coming from the mast. various comm antenas replaced the forward pair of targeting radar dishes that have no point on 054b anymore. Rear pair of targeting radars were replaced with a hq10 - perhaps an overall, having that alongside two type 1130 ciws but what the heck.

engine intake exhaust construction is now a bit larger, possibly allowing for a modified par of diesels needed a bit more air for a bit more power.

Mid mounted ashm launchers are gone, and there's some different arrangement of internal deck or two there. If possible, the mid mounted new VLS (as seen on 052d) is only short ones, with as less deck intrustion as possible - and is a dedicated self defense AAW VLS well.

Forward VLS cells are replaced by the new VLS system but, as seen in the image, divided in new hypothetical 4 cell modules, not standard 8 cell modules. That was 5 of such modules should be able to be put into the same footprint.

Altnernatively, though, perhaps just two standard 8 cell modules would be enough (with the third mid mounted module) and then use the available forward space to install a larger main gun.

I didn't bother with changing the lines of the superstructure so everything else looks the same. Perhaps hangar could be somehow changed though i don't see room for a twin hangar. At best a z20 and a small uav though even that might be a stretch. Hopefully the helipad is long enough for z20. if not, slightly longer hull might be needed.

z20 needs notwithstanding, I would expect the hull and great majority of internal structure under the main deck to be completely the same.

Overall, changes are not small but at the same time they're still not drastic - i think its doable to test the project without a prolongued multi-year testing process. I would expect overall displacement to go up a little bit, but only by a few hundred tons. Different variant of engines and gearbox might be able to cope with it without real changes to internal structure.

A bit more automation and less crew area could give enough extra internal space for all the needs here.

Having even 24 cells of new vls would be improvement over 32 cells of old, smaller vls. The drawing shows as many as 28 cells though, but as i said, if 4 cells could be traded for a larger main gun -it might be worth it.
