states rgearding the planned ASW capabilities:

Integrated Undersea Warfare (IUSW) - The IUSW incorporates two types of sonar arrays in one automated system. The high frequency sonar provides in-stride mine avoidance capabilities, while the medium frequency sonar optimizes anti-submarine and torpedo defense operations. The use of sophisticated target algorithms better enables the Zumwalt Destroyer to engage enemy submarines and, at the same time, minimize crew headcount requirements. The sonar that will be required to achieve this goal includes the following:

Sonar - A dual-band sonar controlled by a highly automated computer system will be used to detect mines and submarines. The arrangemtn will be optimized for littoral Anti-submarine warfare and will include:.

- A hull-mounted mid-frequency sonar (AN/SQS-60)
- A hull-mounted high-frequency sonar (AN/SQS-61)
- A multi-function towed array sonar and handling system (AN/SQR-20)


So, there will be hull mounted sonars. They probably have not attached them yet...or they have come up with some new way of incorporating them into the hull that I am unaware of at this point.

I see...thanks Jeff!

Here is the answer to the riddle. It is not installed on the bow yet.

Watch this video of the Deck House being installed. From time 1:00 until 1:30 you see the main hull brought forward to lower the deckhouse onto it. You will notice the lower section of the very front of the bow shows that another addition has yet to be made there. I am sure this will be the hull mounted main sonar.



Hope that helps.

The Virginia class is meant to replace the principle function of the battleships for heavy shore fire support for amphibious and air assaults near shore (within 75 miles or so)

Don't you mean Zumwalt class Jeff?

I was wondering. Virginia class can do air defense... That's basically the gist of my original idea.

Hehehe...oops! Yes. Of course. Can't explain that one...how Virginia came out instead of Zumwalt. Anyhow, absolutely, the Zumwalt will do all that I spoke of in that post.

Re: Type 052 (Luhu Class)

The CCL VLS is not that much bigger than Mk 41. I can't remember where to pull up the dimensional analyses of the two VLS when 052D first came out, but if you look at some of the overhead shots of 052D and its VLS and compare with similar photos of tico (recalling that both have near identical beams), they are not that much different. That is to say, for the same area which X number of CCL VLS uses, you can practically fit maybe X+1 Mk 41 VLS modules. (depending how big X is)

Zumwalt only has 80 Mk 56 VLS because most of the space on that ship is dedicated to two massive freaking AGS. Replace both with a single 127mm gun and you'd get a hell of a lot of room to fit more VLS. Zumwalt is intended to be a multirole vessel with strong emphasis (I woudl say it is compromised) for shore bombardment capability. The fact that it's 14k tons and "only" has 80 VLS is ignoring its unique armament.

Similarly, if 055 is indeed 12,000 tons then the PLAN are definitely aiming for a cruiser. They don't have a need to put AGS like guns onboard, so what will that space and mass be used for instead? Well more VLS cells and command and control facilities of course. If they have less than 128 VLS I'd be very disappointed, considering ticos are <10k tons and have such a number too.

If PLAN are serious about defending CVBGs and advancing their capabilities they will need cruisers. The requirement for such ships is there.

(And that part about providing fire support for attacking other countries is flawed as well -- having 128 or more VLS doesn't mean you inherently have to load LACMs onboard. ROKN have 3 sejong "DDGs," and they're not out to fire tomahawks at third world countries...)

Only 80 missiles for a big combattant ship ( excluding aircraft carrier which owe their offensive power that their aircraft ) the most large US from the Long Beach nuclear cruiser.

Because yes 2 AGS but also this 4 VLS Peripheral Vertical Launch System (PVLS) with 20 missiles are distributed around the hull and it is much less vulnerable. If there is an impact only one can be destroyed, the ship retains 3/4 of missile power and structural dammage are minored.

At the beginning it was not planned perform area air and ABM defense with Aegis/SM-2/3/6.

This is now confirmed ?

Actually, it's twenty locations of fourcells each, not four locations of twenty, although some groupings may be close together, they are each in their own amrored compartment.

Anyhow, the official designation of the VLS System for the PVLS will be the Mk-57. Gerneral Dynamics, Raytheon, BAE Systems, and the US Navy have all indicated that the MK-57 system is designed to accommodate both existing and future missiles for land attack, anti-ship, anti-submarine and anti-air warfare. Current systems that will be able to be launched from the Mk-57 include the SM-2, SM-3, SM-6, ESSM, Tomahawk and Vertical Launch ASROC missiles Its modular electronic architecture will allow the Zumwalt to migrate faster and more economically to new missile systems by minimizing the need to requalify the launcher for every new missile, or to modify launcher control software and hardware for them. Each cell is larger than current cells on the US Mk-41 and other compatable VLS Systems, but they can still carry the current missiles, up to and including the larger BMD missiles. It is anticpated that future larger missiles with enhanced warheads, payloads, range, and electronics will be developed for the Mk-57.

All of this then allows each of these launchers (four cells each) to be located in a total of twenty armored compartments positioned around the periphery of the vessel for a total of 80 missiles on the Zumwalts. Each PVLS compartment contains and protects one MK57 Vertical Launching System. This design makes launchers and missiles resistant to battle damage because the armor is designed specifically to take a hit and then project any explosion, particularly secondary explosions, outward, away from the vessel. This helps to safely isolate the crew and equipment spaces from more catastophic damage.





Here are the PR Diagram pictures of the vessel being used to advertise its capabilities:

So how many VLS missiles will this carry

Pretty crazy to think that USN planned 32 of these boys

There will be 80 cells.

Maybe a loadout would be something like this:

12 x 4 ESSM
24 X Tomohawk
32 x Standard Missiles
12 x ASROC

That's 116 total missiles.

But what the standard will be is something not determined, and something that is going to vary according to the mission. For big fire support missions, maybe they will have more Tomohawks and less of some of the others...for example:

08 x 4 ESSM
32 x Tomahawks
32 x Standard Missiles
08 x ASROC

That's 104 missiles total.

Lots of combinations...because then you have to break down what type of Standard Missiles they carry depending on the threat environment, and what type of Tomahawks they carry depending on the mission.

Maybe in an air defense role they carry:

20 x 4 ESSM
12 x Tomahawks
40 x Standard Missiles
08 x ASROCS

That last load out would make for a total of 140 missiles.

We'll just have to wait and see...but, as I say, there are lots of combinations.

Ok Jeff, you do the job !

But this 20 small VLS are divided into 4 different locations.

I think it has no Aegis and BMD systems.
