I am wondering if anyone has statistics on its power compared to world navies, and how many of the world's nations could it destroy single-handedly. I am looking for statistics put out by either the DoD or General Dynamics that state the ridiculous power of the new DDX class destroyer.

US Destroyer

If you follow the "not routinely deployed" option then quite a few, there are some Nuclear Tomohawks left, although not always carried afaik know they are still deployable on a Destroyer that would make short work of most small to medim nations, now that youve stated the ddx, Monaco and Vatican city would be at risk for sure.

Well, maximum payload is 96 Tomahawks on each DDG, if all VLS are filled with Tomahawks instead of SM-2 and ASROC ASW missiles.
That's enough to destroy a few airfields, op centers, radars, harbor facilities, etc. while remaining 300+ miles away from the enemy shores.

No other country matches such as a payload.

However, if you were also asking of a DDG's performance vs air or naval targets, then it's more of an even match. A SM-2 III or IV AAW missile has a comparable range to the European Aster 30 missile (100 km / 60 miles) or to the Russian SA-N-6 Grumble. From an ASW perspective, towed array sonars and ASROC missiles and torpedoes are comparable to European equipment.

well well single handedly although that would be nice,you really need to make your qeastion more clear

An AB can sink most small fleets of the world singlehandedly. She can even take out a CBG within 80nm with her full CAG. She can run out of TASSMs, say shot down by phalanx, and close to within 60nm and engage with guns (Flight IIA).

The Zumwalts/DD(X) are not a major leap in power from ABs, in fact they are less capable in ABM but better at hitting cruise missiles. The purpose of Zumwalts are for littoral operations not blue water power projection. They obviously will have better survivability but they are not invisible or invincable. It is not the first version of DD(X) thats going to be amazingly powerful, it's going to be the second generation using her IPS with DEW and EMLs that will make her an awesome destructive force.:ar15

Sorry if I appear thick but you are saying DD(X) is not as capable as the AB. I am a little confused, I was under the impression the thing will carry the next generation AEGIS, weapons at least as capable in so far AAW, ASUW and TLAM are concerned (as I noted previously I don't know what is intended with Harpoon on these unit as I understand it is not currently VLS capable) with improvements planned, have lower RCS, carry the latest word in networked combat system and have survivability improvements over the AB. My impression was that it will be a milestone increase in capability

I don't understand why you would bother with the horrendous cost of DD(X) development if it did not offer a substancial leap in capability over the AB. If that was the case why wouldn't you simply build and evolved AB? Particularly when it can sink most small fleets single handed (the RAN probably qualifies as small).

This may be the place to put this question in.

Is Navy League Sea Power Magazine getting this wrong or can an AB only use 2 faces of the newer AN/SPY(V) at the same time?

The new SPY-1D(V) is designed to spot low-flying, low-radar cross section, high-speed threats in severe clutter and against sophisticated countermeasures. One of the most significant improvements is in the computer program. For example, “dual-beaming” is a new feature that nearly doubles the rate at which sailors can search the combat air space; it involves two opposing array faces simultaneously sending out and processing pulses. Previous generations of SPY-1 radars could only transmit from one array face at a time.

If true, it should be possible to think up some nasty ways of taking out an AB with a simultaneous arrival cruise missile attack. But of course an AB would not be let exposed like that. ;)

Btw, the 5" Mk45 Mod 4 has a range of 24 n miles and the ERGM will use 5½ minute to reach out to 50 n miles. It will be difficult to hit a moving target.

It will be a milestone in survivability but the thread was about power which I take to mean offensive capabilities. The ABs will have the same types of weapons as DDG-1000 just with different mixes of munitions in her tubes for MS. Pretty much the same power projection just better survivability and defense.

You have to replace Spruance with something and DDG-1000s are the design of the future. Right now the main theme of the ship revolves around her AGS system to fight in the littorals but she will also play a part in ABM and fleet defense. These are only the stop-gap capabilities of this ship. She is fully designed to incorporate future technologies. Her incredible survivability along with IPS will make the perfect platform for Directed Energy Weapons and Electro-Magentic Launchers. She has been specifically designed to incorporate these two technologies into her architecture.

Whoa there Big E.

With all due respect as I understand your a Lt. in the USN.

But the conjectures in the above statement dont make much sense and from what I know is factually wholly untrue.

Maybe you would like to clarify your statement and fix its factual errors?

Sure, I was working on a scenerio but I think it would be better if you give me one of a certain force and I'll tell you how the DDG-81+ would deal with it.:D

All things considered a US DDG is about as powerful a surface combatant you are going to get outside the USN. But they really arent designed to fight major engagements as stand alone platforms. Remeber as powerful as they are a relatively primitive airforce with enough mass or a powerful surface combatant with decent AShM's would be able to get pretty close due to the curvature of the Earth and potentially cause problems. If you really want a stand alone platform that could go toe to toe single handedly with entire Navy's then think Seawolf, Virginia, Los Angeles or even Ohio SSGN's. Now those are real purpose built stand alone platforms excluding off board ISR data of course.

How well can a DDX defend itself against Brahmos, Yakhont, Moskit, etc? Let's say a volley of 24 missiles, launched from Su-34s and various naval craft against a US carrier group. How many would get through?

All of them would get thru and keep on going past DD(X). If she is doing fleet defense, which would be tasked to CG(X), she still has ESSMs in conjunction with AN/SPY-3 which has a good chance of intercepting dozens of threats before they reach critical impact. In conjunction with CG(X) in a CBG they would have to extiguish the VLS before something got thru, unless they got lucky which is always a possibilty.

A DDX or DDG in a US CSF? I'd say they would do pretty well. Their defenses are designed to deal with those types of threats. AEGIS isnt really a single weapons system. Its like the ultimate net centric warfare system. Fighting a single AEGIS/CEC capable ship in the CSF is like fighting them all as well as all the aircraft in the group.

To succeed that 24 missile volley would have to be very well planned and executed to have even a remote chance. An Oscar II could potentially achieve some success in an attack like that due to its stealth. But I would say the odds are with the CSF vs the planes or surface combatants if all you've got is 24 missiles to offer.

First time I'd have to disagree with you Darth. Submarines do not make good stand alone platforms when faced off against a dispersed surface fleet. They have limited SA depending on passive sonar to detect targets. Once they engage a target with ADCAPS or TASSMs they give away their position and get to kill a couple ships before they are torped by a helo.

No arguements about the capability of the AB which is the reason I am glad to see the new AWD being based on this design. There are other classes of vessel based on the same platform that are also pretty good (the Kongo being a prime example). But the idea that this is a stand alone beat everybody hands down vessel has problems IMHO. A small force supported by effective survailance assets and decent SSMs would have the potential to put a single AB at serious risk (particualry where that force is a modern AAW ASuW capable vessels). Particualry in light of the gun based CIWS fitted tot the AB. There has been an ongoing discussion in the forum to the effect that gun based CIWS are a real hail mary approach and that missile based systems such as RAM providing a better last line of defence.

I struggle to accept that:

If I was on a ship that had expended it stocks of SSMs I doubt I would be racing into engage a 'small fleet' (unless they are gun armed patrol craft) with guns, particularly where the opposition may have some missiles left.

This is not meant to turn the discussion into a platform verses platform arguement but is simply to make the point that the some claims need to be tempered.

I see I am going to have to explain without someone giving the example I requested. Lets put DDG-81 against the entire Brazilian navy in open blue water. The longest range weapons this fleet has is A-4s with exocets, DDG-81 is armed with SM-2(IIIB) with 90nm range shooting down every air asset in the Brazilian fleet. The fleet is left with MM40 Exocet SSM as their best weapon, with a range of 43nm they are at the mercy of TASSM attacks. Lets say 40 are carried as the TLAMs are left home and probably punch thru the weak air defenses of the fleet knocking the front line destroyer escorts and sinking Sao Paulo in the process. Lets say this strike wipes out A12, D27-30, and F46-49. With the 40,000lbs of ordinance in this strike this is a highly possible outcome. Lets say the remaining SM-2(IIIB)s knock out every flight platform in the fleet so you are left with the Churchill armed with her 63nm ranged Mk 45 MOD 4 Gun system against 43nm MM40 Exocets. So the ERGM rounds open fire before Exocets can be launched and all thats left in Brazils surface fleet are 4 Mk10 frigates and 4 Inhauma light patrol frigates. Churchill uses her advanced range to criple, not sink, the 4 Mk10s. With all SEACAT and other SAM systems sunk or inoperational the SH-60s can move into torpedo or Peguin (AGM-119) range and open fire outside of the light frigates air defense. Needless to say all their surface combatents are sunk. S30-34 are about waiting for the Churchill to come within weapons range but never does. The SH-60s search find and destroy 2 of them. Churchill lands her helos and hauls butt! Thats how she can do, her weapons outrange everything they have. Besides I never said the opposing fleet get shore based assets... did I?:rolleyes:

I love these scenarios ;)
How about a tougher scenario ?
Let's say your Burke Flight II DDG is north-east of Taiwan, close to the small islands that Taiwan, Japan, and China all claim, mostly because there's oil below. The Chinese Navy almost always has several ships and subs deployed around the areas for "flag-waving" purposes. Your DDG is facing 2 Sovremenny and 2 of the newer Chinese DDGs, all of them with the extended range Sunburn supersonic SSM, plus 4 improved Kilos SSKs equipped with Yakhont cruise missile. An air patrol of a dozen SU-30s armed with the air-launched version of the Uran is in the sky.
If your DDG were to be ordered to attack, because for example the carrier air group has just been attacked south of Taiwan, and if your DDG were alone...
I guess the DDG would kill most of the Flankers and sink with the TLAMs the enemy destroyers. However your DDG would still have to face at least a dozen Urans and 20 or so supersonic SSMs. The ESSMs and RAMs/Phalanx may shoot down a dozen or so. However some would nonetheless get through...
Even if the enemy DDGs and SU-30 were destroyed before being able to launch, which would be possible since in this scenario your DDG would receive the order to engage before being shot at, you would still be facing up to 16 Yakhont from 4 separate locations. Ouch... Your 2 helos plus the ASROCs might kill a couple, but not more.

Your DDG is most probably the best naval surface escort floating today, but there are limits to what it can do alone.
