US Navy DDG 1000 Zumwalt Class

As I said on the other thread...this four-five month delay is not a major issue IMHO.

As you say, they are high tech and new...and they are cruiser sized DDGs employing all of the new systems.

Still getting Zumwalt in 2015, Monsoor in 2016, and then LBJ in 2018 means they will all be operational before 2020...and that is a good thing, and will lead to many other good things as their new tech is integrated into the fleet.

Maybe I am influenced by the look of the Zumwalt but I like to think that when they become operational it will be a new era in the history of naval warfare, like when ironclads were introduced. Rail guns and lasers to say the least!
 
First two ships of the Zumwalt Class look to be delayed.

Not really surprising considering the amount of new technology involved in these impressive ships.

already now I'm looking forward to hear the results of their shake-down, as I've seen texts with several types of predictions related to the hull stability, from like "a revolutionary improvement" to "she might sink" :)

She's not going to sink.

Nothing even close, while operating her at sea in the conditions she is designed for.

Her Tumblehome hull form is not new. It was used in oared combat vessels, in sailing vessels, and particularly in battleships of the late 19th century (1880s on). The design itself has some positive points which include reducing the weight of the upper deck, actually making the making the vessels more seaworthy in many conditions and increasing their freeboard. It also has some drawback. In the past, if their water-tight integrity was breached and they took on large amounts of water (and weight) they could become dangerously unstable. Also, in sharp turns in high sea states, they could also become unstable. But today's technology makes it very possible to overcome these weaknesses, take advantage of the strengths...and particularly to help increase her stealth characteristics.

The US Navy built an operating scale model and tested it in detail for years before moving to the full design.

My guess is that she is going to do just fine in terms of handling.

If it is any consolation, this is a picture of the A yacht - a 390 ft luxury yacht built in 2008. She hasn't sunk yet. Lol.

We do not have to go back nearly as far.

The early Tumblehome battleships didn't sink either from handling.

The Russians lost ships to the Japanese due to taking on water from combat and the instability they experienced. But that was long ago and the water tight integrity, damage control, and capabilities of new technology make that very less likely with a US Navy combat ship.

Although, if you do enough damage to a ship...it will sink regardless of hull design.

But the US learned from those lessons.
 
a railgun for DDG-1002?
Navy Considering Railgun for Third Zumwalt Destroyer
Engineering studies to include an electromagnetic railgun on a Zumwalt-class destroyer (DDG-1000) have started at Naval Sea Systems Command, NAVSEA’s head said Thursday.

The work will do the math to determine if the Zumwalt-class will have the space, power and cooling to field a railgun – likely replacing one of the two 155mm BAE Advanced Gun Systems (AGS) ahead of the ship’s deck house, Vice Adm. William Hilarides told USNI News following remarks at the

.

“We have begun real studies – as opposed to just a bunch of guys sitting around – real engineering studies are being done to make sure it’s possible,” Hilarides said.

The likely candidate for the weapon would be the third planned Zumwalt, Lyndon B. Johnson (DDG-1002) currently under construction at General Dynamics Bath Iron Works (BIW) with an expected delivery date of 2018.

He said the first two ships – Zumwalt (DDG-1000) and Michael Monsoor (DDG-1001) – would be less likely to field the capability initially due to the schedule of testing with the new class.

“The team is working diligently now but it would not happen until after delivery of the ships – probably the third ship is where we’d have it,” Hilarides said.
“That would certainly be my recommendation.”

The Navy is in early stages of testing and fielding a railgun – which forgoes the gunpowder in the shells of conventional naval guns and instead uses high powered electromagnetic pulses along a set of rails to shoot a projectile at super sonic speeds.

The Navy plans to test a BAE Systems prototype railgun onboard the Joint High Speed Vessel USNS Millinocket (JHSV- 3) next year.

Last year, then Navy director of surface warfare now commander of U.S. Surface Forces Command,

the Zumwalts would be likely used as test beds for emerging technologies like railguns and directed energy weapons the Navy wants for its next large surface combatant due to the ship’s size an ability to generate power.

on the 16,000-ton ships– powered by two massive Rolls Royce MT-30 gas turbines and two smaller Rolls-Royce RR450– allow the ships to route and generate 80 mega-watt power – much more electrical power than the current crop of U.S. destroyers and cruisers.

On Wednesday, Chief of Naval Operations Adm. Jonathan Greenert said a Zumwalt would likely be the first ship to get the capability.

The inclusion of the railgun does mean a capabilities trade for the ship.

“We’ll go do the studies and I suspect they’ll say ‘yes,’ but it’s going to come at a cost of some of the capabilities on this ship – of course,” Hilarides said.
“It’s physics. Without taking something off, you’re not putting on a many ton system, so a gun would be a logical thing to take off and put the railgun in its place.”

The three ship Zumwalt-class were – in part – originally designed to address a gap in naval surface fire support with the AGS firing the Long-Range Land Attack Projectile (LRLAP) at a range of up to 75 nautical miles.

Each ship is designed to field two AGS.

Zumwalt is expected to deliver to the service next year.

That would be awesome if the 3rd Zumwalt has it! It would truly put the Zumwalt in a league of it's own with no peer.

The only down side is the darn thing is so costly they can only exist in extremely limited numbers but the early adoption of new technologies in the Zumwalts will hopefully pave way for eventual real economies of scale down the road.

I like to see 'frigate' size Zumwalts with 'smaller' rail guns sometime in the future.

I think they should just revived the old Iowa-class battleship and put railguns on it. With 9 × 16-inch railguns it will literally blow all competition away!
