Ooooooh Kaaaaay

Normally one doesn't assume a contrary stance when a third party is basically supporting your argument.
My stance isn't contraty, it's the truth. I'm for reactivation. However I will not lie or twist the facts. You see, when I originally came to DT.com I started a similar thread to this and got in a huge arguement with GF about it (which I will take the time apologize for now, sorry) and I really didn't have a clue. Since then I have gone and joined many forums and had in-depth dicussions about this topic. Even after all of it I'm still for reactivation, but now I'm much more...educated on the subject. My stance is for the truth, not merely to agree with anyone just because they support me, since that won't actually help my arguement. Plus I would like to share what I've learned with like minds as well :)

But given the 290 shots per gun, unless there was a way to extend that life by a factor of 4 to 6, the project is not worth it.
The barrel life listed above was that achieved during World War II, with an HCC round causing about 11% as much wear as an APC round (0.11 ESR). At that time, Nitrated-Cellulose (NC) was the standard propellant. Following World War II, Smokeless Powder Diphenylamine (SPD), a cooler-burning propellant, was adopted in order to prolong barrel life. In the 1967 and 1980s deployments, the use of "Swedish Additive" (titanium dioxide and wax) greatly reduced barrel wear. It has been estimated that four APC shells fired using this additive approximated the wear of a single APC shell fired without the additive (0.26 ESR). Later development lead to putting a polyurethane jacket over the powder bags which reduced the wear still further. This jacket is simply a sheet of foam with a fabric border around the ends that is tied to the powder bag. When the jacket burns during firing, a protective layer forms over the surface of the liner which greatly reduces gaseous erosion. This wear reduction program was so successful that liner life can no longer be rated in terms of ESR as it is no longer the limiting factor. Instead, the liner life is now rated in terms of Fatigue Equivalent Rounds (FER), which is the mechanical fatigue life expressed in the number of mechanical cycles. The 16"/50 (40.6 cm) Mark 7 is now rated at having a liner life of 1,500 FER.

As brand new you are talking 958 000 USD per round to be launched (as is) without the money being spent on extended range technologies and production of new projectiles.
? A new 16" shell would cost roughly 1,800. Not 958,000 dollars. Perhaps your talking about barrel life? In which case I addressed that above. Nevertheless 16" gun tubes aren't that expensive.

That is not to say you couldn't do it, but it is where the focus on this debate should be directed.
Directed to what?

And that proves what? Please explain to me why I should use an ultra-heavy missile for ANY engagement? Why are they obsolete today, when the overwhelming part of warship force consists of rather small ships (in WW2 terms) not even crossing the line of 10,000 ts and being unarmored. Exocet clearly demonstrated it was able to get the job done in the Falklands.
Exocets are generally carried by aircraft. Nevertheless your assumption about the shipwreck is incorrect since only the Kirov class battlecruisers carry them. And theres only one of those operational. Thus it actually does make sense if you had to engage a super carrier.

Why were missiles like Exocet and Harpoon developed in the first place? To destroy aircraft carriers or BBs? If you think so then you are missing a point here that has to do with real threat assessment by NATO forces. Is there a credible target for such a heavy missile employed by western forces today. The answer is more than obvious.

The ShipWreck is a russian missile, and I believe it is properly thought out considering the supercarriers used by the U.S.


Feel free to give some information about these other ships. I am not aware of any such incident.
Sorry, I meant to say other ship from foreign nations.


Actually there is no DDG(X) at all, but you posted the naval forces mix already, being DD(X)+CG(X)+LCS (besides CVN, LHA etc.). From the last official pictures I have seen the CG(X) is the exact same design as the DD(X), featuring roughly the same displacement, but dropping one of the AGS in exchange for increased missile capacity. Thats why they are talking about the DD(X)-family evolved out of the DD-21. Most of these specs can be found at
http://www.globalsecurity.org/military/systems/ship/dd-x-program.htm

I'm afraid they dont have CG(X)-pictures yet.

Actually I am completely right and you are completely wrong.

The DD(X) is not going to replace the burkes. The DDG(X) is.

Evidence for what I have said comes from the U.S NAVY's 313 ship plan that can be found here: http://www.cbo.gov/showdoc.cfm?index=6985&sequence=0

The 313 ship plan is an official report that was released last month (dec 05) from the United States Congressional Budget Office and gives in-depth detail to the most likely fleet plan that the USN will use.

The following is from page 7, paragraphs 2,3 and 4:
The Navy’s plan would buy seven DD(X) destroyers at a rate of one per year starting
in 2007. Press reports indicate that the Navy hopes to reduce the cost of the
first two ships of that class to $3.1 billion, with subsequent ships costing about
$2.0 billion. CBO estimates that the cost of the first ship would be $4.7 billion
and that the average cost for a seven-ship class of DD(X)s would be $3.7 billion
(see Table 2).
In addition, the Navy intends to begin buying a new missile-defense surface combatant,
the CG(X) cruiser, in 2011. CBO assumes that a CG(X) would use the
same hull—and cost about the same—as a DD(X) destroyer. However, the
CG(X)s would have a lower average cost than the DD(X)s because more of them
would be bought (19 between 2011 and 2023) and because some CG(X)s would
be purchased at a rate of two per year, reducing their unit cost.
The Navy’s 313-ship plan would also maintain a fleet of 62 Arleigh Burke class
destroyers (DDG-51s). CBO assumes that those ships would be modernized and
would serve for about 35 years, which is consistent with the Navy’s plan. Under
that assumption, the first replacement for the DDG-51s—a DDG(X)—would need
to be purchased in 2020.
11 For this analysis, CBO assumed that the new DDG(X)
would be somewhat larger than existing DDG-51s but smaller than DD(X) destroyers
(since it would be unlikely to carry the advanced gun systems that DD(X)s
have). In particular, CBO assumed the DDG(X) would displace about 11,000 tons
at full load. In CBO’s projection, those replacement destroyers cost an average of
about $2.2 billion apiece—the same cost per thousand tons as today’s Arleigh


As you can see they very clearly state that there is both a DD(X) and a DDG(X). The difference is that the DDG(X) is replacing the Burkes and the DD(X) isn't. The DDG(X) is also as I said before, smaller than the DD(X). They very clearly state such. Furthermore they clearly indicate that there will be a CG(X) and if you take the time to download and read that report they affirm what I have said to Rich about only 7 DD(X)'s being funded, which will not be operational until 2013 at the soonest.

As you can see my information is far more up to date and accurate than globalsecurity.

@Wookie:



Trust me, I got some idea about that. But why developing a missile which should do that when there is no respective target? And that was the whole point in my response to defcons assessment and his very general dismissal of the Exocent and Harpoon being "nothing to fear about". How long do you think it would take to develop and field an appropriate missile in order to penetrate said armor. Now compare how long it takes to actually design and build the respective BB. In the end you got a very big very expensive and very dead BB.
There is a reason behind todays warships not fielding any significant armor protection anymore.
And any other ship in the world would also be just as dead. nevertheless armor is helpful against some weapons. At any rate I already explained this to the poster.

Furthermore I will also point out that it is unlikely that the DD(X) will meet price projections of the USN. As my 313 ship plan source has stated the USN needs the price down to 2.0 B and the CBO believes the average price will be about 3.7 B. So Iowa reactivation is looking better and better. Furthermore many of their other ships seem to be budget breakers as well. Gotta love those cheap Iowa's. So as you can see Iowa reactivations costs PEANUTS compared to other projects.

Defcon your losing me here. You still havnt posted a reliable source that more then one 16,000 ton DD-21s are going to be built. Again, as far as I know, and until someone shows me different, the eventual DD-X and CG-X will be built on the same hull design and they will come in in the 12,000 ton range. There isnt going to be 7 16,000 ton DD(x)s being built.

No I already answered that Rich. When I said the most recent information on global security says 14,150 t, meaning 16,000 at capacity (fuel, ammo ect ect.)

Furthermore we don't know what the tonnage of the DD(X) is. Your aware of that right? Just to let you know, all 7 DD(X)'s are going to be pretty much the same tonnage.

Its simple 2.5 billion ( the proposed figure for reactivating an Iowa BB) divided by the number of times you can shoot your gun equals how much it costs to fire the weapon once.

Really, it should be [2.5 billion + extended range munition development + production ]/ number of times you can fire the gun = the cost of firing the gun once.

Then compare that to the cost of firing a cruise missile and you have a quantitative case for or against starting the whole program.

So now you are saying that a gun has a life of 1500 firings. Which is great.

2.5 billion / (9 x 1500) =185185 USD per shot. That is a lot better but it still is not enough when you add the development costs for the extended range. A cruise missile will beat it every time.

How much has the AGS program cost? That would be a good figure to know and then you can get closer to generating a target figure for gun life to make the whole thing viable.

See, this is what this thread was intended for. People who "know," getting together and talking about how to get these fish back in the sea.

Let me go look for the AGS budgets.

But you put
2.5 billion / (9 x 1500) =185185 USD per shot.
So I think thats per salvo? 9 guns per ship, firing all 9 cost that much?

no, that is for one shell, you have 9 guns on one platform so that increases the amount of times you can fire a round. i.e 9 lives.

The premise for this logic is

1) that the sole purpose for bringing back a BB is to use its gun
2) that the technology does not exist to re gun it once a gun is "used up"

No.2 is a valid point as everyone who developed that weapon is either dead, or has one foot in the grave. So if you want to replace the gun, you have to add that as a development cost to the platform.

And that is why I alluded to something about "maybe the rail gun tech will be ready by then" or some such thing.

A missile is easy to figure out. You have your DDX platform. You fire a missile,

[DDX platform cost + munitions costs + running costs]/ No. missiles fired = cost to fire a missile.

So the more you fire missiles the cheaper it becomes as missiles don't require a launcher (a gun) per sae that has a significant cost to it. The technology is easily replaced or repeated, where a 16 inch gun is not. Having said that the missile has an intrinsic value that is higher then a 16"shell e.g. 550000 USD as opposed to ~10000USD

So, if you pony up the cash to make replacing a 16 inch gun a non event, then you have given your platform (BB) the same "competitive edge" as the DDX.

All you need to do then is find a technology that will extend the life of a gun to make using the weapon cheaper and that is how you reach a point where it becomes cost effective for the USN to reactivate an Iowa Battleship.

Rummy loves this stuff.

Why? The beauty is that making the BB cheaper also makes the DD(x) cheaper because it uses guns too.

The 155mm DD(X) AGS = 376 M USD.
Ok, so lets say making a new 16" gun facility and developing an extended range munition costs 500 milllion.

Now you have 2.75 billion/ v/l... so you would need a gun life of about 20000 shots to bring the cost down around 20000USD per shell fired.

2.75 billion / (20000x 9) =15278 USD + shell cost.

huh...

Well isn't it lucky for you Deffy that there may be a technology that can do that. I did add another paragraph but I am editing myself now :D

Time to have a think about it anyway.

What about smoothbore technology? As far as I know they've never been used for naval applications. Doesn't seem like they would be useful in in-direct fire...but with guided munitions they could be. Come to think of it, smoothbore ammunition is stabalized with fins, so...I don't know. What do you think? Smoothbore' generally have much greater barrel life.

Well, I think this thread has run its course. I love battleships because they are part of naval history.

Type 45 Destroyer is set to be launched soon...new things, new technologies!

Defcon, it is wise to listen and respect opinion of people who are in the business rather than going on and on about what you know through reading about such technologies online.
