At the Bat Iron Works shipyard the Zumwalt class lead destroyer was launched

The US Navy announced on October 12 at General Enterprise Bat Iron Works' facility in Bat (Menn) that the Zumwalt-class head destroyer was launched.

The ship was removed from the dry dock and moored at the quay wall on the Kennebec River, where it will be completed.

The destroyers of the DDG-1000 Zumwalt project belong to the latest generation of multipurpose destroyers of the US Navy URO and are designed to ensure dominance fleet in coastal waters, the destruction of ground targets and fire support operations of the units of NE and the United States Marine Corps.

Initial contracts totaling 2,8 billion for the construction of two Zumwalt-class destroyers (DDG-1000 and DDG-1001) of the US Navy concluded with Bat Iron Works and Northrop Grumman Shipbuilding in February 2008. The construction of the ships began in February 2009. It was originally planned to deliver the US Navy 7 class destroyers "Zumwalt", but in April 2009, due to a significant increase in the cost of the program, it was decided to reduce the order to three units. At the same time, the Bat Iron Works' shipyard was chosen as the main contractor for the construction of all three ships.

Construction of the DDG-1000 began in February 2009 of the year. The destroyer keel was laid down at the Bat Iron Works 17 in November 2011. Currently, the destroyer readiness exceeds 87%. The DDG-1000 delivery of the United States Navy is scheduled for the end of the 2014 year.

The length of the Zumwalt-class ship is 610 feet (185,9 m), width - 80,7 feet, displacement - 15000 t. The shape of the superstructure and the special design of antennas significantly reduce the effective scattering surface. Maximum travel speed - 48 knots. The crew of the destroyer - 158 man, including the air group of 28 man.

The ship will be equipped with the latest weapon systems and will surpass the existing destroyers in firepower three times. It is assumed that the weapons of the destroyers will make 80 vertical launchers with Tomahawk, ESSM, and Standard missiles; 155-mm AGS advanced shipborne artillery systems firing 155-mm long-range Land-Attack Projectile long-range guided artillery; anti-torpedo and anti-missile weapons.

The DDG-1000, 1001 and 1002 destroyers will also be equipped with the X-band SPY-3 multi-function radar.

The ships will carry on board two MH-60R helicopters or one MH-60R and three unmanned aerial vehicles with vertical takeoff and landing.

As planned, the destroyer DDG-1000 will reach a state of initial readiness for combat use in 2016.

The second ship of the Michael Monsour series (DDG-1001) will be launched in the 2014 year and handed over to the US Navy in the 2015 year. The construction of the third destroyer Lyndon Johnson (DDG-1002) began in April 2012.

Well, what are you ... :) one must be happy for our partners ... Let's congratulate the USA on another hole in the budget!

[rrrd]

I can only rejoice in their assertiveness! Let and wash, and so on! But all the same they are doing something!

[Orel]

Nevertheless, they are doing something!

We will not be jealous. We have problems with the construction of ships, but they are gradually being resolved. There are no miracles, but we gradually begin to build modern ships and go from small to large, because during the stagnation, much has collapsed and is now being re-created. At first we only made boats, but now we have reached the corvettes and frigates. Maybe we’ll reach the destroyers soon. While the United States does not compete with the sea at sea, but it may not be necessary, for us the security of a retaliatory strike with the help of nuclear submarines is more important, and then we will see what the situation will be in the world and in the economy, maybe we will survive to full-fledged aircraft carriers ... And Zumwalt is not bad, let's see what happens ...

[Dangerous]

Americans are not afraid to experiment with shapes - remember the same F-117 and B-2, now here is a destroyer of an unusual shape. In Soviet times, ours also did not hesitate to supply "exotic" to the army, for example, ekranoplanes, and now ... eh ...

- Why did you decide it was gone? It is not clear to me ... SU-27 and MiG-15, let it be known to you, are very daring planes, according to the "unstable integral triplane" scheme. The Americans considered such an option for their prototype F-15, but did not dare, and the Russians decided and created. And in my opinion, the SU-27 derivatives are significantly superior in flight characteristics to the F-15 derivatives. Now, within the framework of the MS-21, a number of bold innovations, when developing a wide-body aircraft (it seems like it is planned with the Chinese), will most likely risk an extremely bold so-called. "oval" fuselage.
So you are erecting a vain slander. Americans, of course, well done, feel free to experiment, but among Russians, the combination of conservatism and innovation is usually better, hence the share of successful innovations among Russians is greater. When creating Russian UAVs, you will also see a number of interesting technical solutions, including and interesting experiments with forms, I'm sure of it. And the fact that you have not seen them so often lately is that the 90s go around, they just started to come to life, there will be more.
Py. Sy. Unlike amerskih aircraft of the 5th generation and their helicopters, with all my dislike for amers, I have due respect to this Zumvalt development. Serious thing. Americans are all-Thai power, born to swim cannot fly, so they would not torture themselves ...

What can I say, the iron is the iron, It will beautifully go under water, it is unlikely that its weapons will save Onyxes, Yakhonts, Bramosov or Caliber !!! Let mattresses invest more money in such projects, although they have their own printing press, but the bottom of the state economy sooner or later will go and such projects of irons or F-35 will help that !!!

Let's see how he shows himself on the chassis. Once I wrote about the controversy of this project, here we find out whether it was right or not. Although there is reason for envy. They do it quickly, and even new developments.

[Captain Vrungel]

Multipurpose, with emphasis on coastal and ground targets. Head DD-21. Judging by the contours of the hull, it seems that the add-on to the bottom stuck. Such a ship piercing the waves, but with serious weapons.

Quote: Captain Vrungel

Such a ship piercing the waves, but with serious weapons.

This is what confuses me. One of the biggest drawbacks will be the deck bay and burrowing into the wave. But this is my personal opinion that rolling on a wave is much more effective than "piercing" it.

[Ptah]

Quote: Mechanic

deck bay and burying in the wave.

This is what immediately comes to mind. When burrowing into a wave - a sharp drop in speed, an increase in the load on running machines, propulsors, shafts. Hence the additional (stabilizing) mechanisms - an increase in displacement.
The impact of the incoming stream falls on the cannon tower and superstructure - strengthening the structure, increasing the mass and displacing it up. The drop in overall stability entails the addition of ballast, which reduces the "useful" area and again the excess displacement.

Seaworthiness, let's say right away, is low. But it is said that for coastal navigation. With the deterioration of weather quickly into the harbor.

We are expecting from the Americans a video with Zumvolt during a storm, well, something like this:

Ay, power aaa! What a "bad power".
And how the scale is superimposed on the topic. Maybe Morricone?
When I see such pictures, the hair on the scruff of my neck gets up and my hands involuntarily look for some handrails.
To treat this calmly requires nerves like propylene mooring lines, a "disconnected / broken" vestibular and an adequate environment.
When I first got into such a gimmick (although from birth with my parents in a boat on large rivers), the commanders immediately said:
"You rookies, get together somewhere closer to the DP, so as not to see what's going on overboard, grab whatever you want, just don't close your eyes and stay up. Drink plenty, piss in a canister and you can shout or sing in chorus."
Later got used to it, although it’s impossible to get used to it.

It’s not quite true, with a positive collapse of the sides, the bow rises, the ship must somehow rise to the wave, which it really can’t do, respectively, the speed drops, it picks up speed ... and the next wave. With negative collapse, the entire hull does not rise (or rather, it is much smaller), since the deck is empty in all respects, and it is easier to take 200-300 tons of water onto the deck than to lift the entire hull with a displacement of 15 tons. This is not all I came up with, it is now fashionable trend. Too lazy to look for the name, but there are ships with a much more "streamlined" appearance.

[alex86]

Quote: alex86

Too lazy to look for the name

Not too lazy, this architecture is called X-BOW, in the case of Zumwalt, this architecture is not so obvious, but given the speed of 48 knots (something cool for 15 tons of displacement), it is understandable.

[Ptah]

Quote: alex86

in the case of Zumwalt, this architecture is not so obvious

There is no X-Box on Zumwalt at all -

Advantages of the X-BOW design:
- Increased cruising speed on calm water due to low entry angles and increased waterline length
- Lack of a nasal bulb improving safety when towing and mooring
- Smaller vertical and airborne accelerations
- Reduced noise and nose vibration due to soft wave entry
- Less spray
- Slight penetration of "green water" (corrosive sea water) on the deck and bridge
- The working deck and deck equipment are better protected due to the greater width of the hull
- Increased cruising speed under adverse weather conditions, which leads to a decrease in energy consumption and / or high fuel efficiency at sea

All this I meant. And he stipulated that in this case X-BOW is not so obvious due to the high speed, i.e. nasal contours are not rounded, because you do not need to save length, you do not need a tank developed upwards, etc. - the ship is a military one, the approaches to the design are different.
So, from my (I emphasize) point of view, we have a "degenerate" X-BOW principle applied to a high-speed and military ship.

Additional complication of the set (reinforcement of the structure), which does not contribute to a better "wave output".
As you rightly noted, if there is a delay with the "discharge" of the leading water, the next blow will follow, already into the deck mechanisms and superstructures.

with positive camber

What is meant? As far as I know, this angle is measured from the vertical to the sides. And it is different along the entire length along the frames (the side is smaller, the cheekbone, to the nose - more) For example, in "Burks" from 8 degrees. up to 35. We see that the "Zumwalt" slope of the sides, as it were "inward" (stealth architecture). Then we can consider that "negative".
Also with the nasal tip. "The angle of inclination of the stem" - from the overhead line upward. If you count more than 90 degrees. "negative" - ​​maybe .........

Quote: Ptah

does not contribute to the best "going on the wave".

So this is not necessary, he took his 200-300 tons of water on an empty (note) tank, they will not reach the superstructure - far, the hull does not rise to the wave - thus. energy of translational motion is saved - it is not translated into potential energy of ascent to the wave - and indeed, the wave is pierced. If you remember, then in France the option of a semi-submerged "Spruence" is being considered, this, of course, is not "Zumvalt", but the general idea and (I do not like this word, but where to go) the trend is now such that the open decks (spaces) are empty and presence a person is not demanded and even excluded.
So, I think the architecture of Zumwalt is well thought-out, albeit strange at first glance. And it differs fundamentally from what we are used to, when the entire deck is packed with various weapons. But we are also heading for something similar, I think it's only a matter of time and expediency for northern conditions - well, are we going to bury ourselves under the ice (just kidding)?

[Ptah]

Quote: alex86

Not a joke at all, but a logical continuation. Especially "in the light of the ongoing struggle for the Arctic." Russian Arctic !!!
I remember that in childhood in the magazines "Science and Technology", "Tenika-Youth" and others. PROJECTS of semi-submersible vessels for ice navigation with a sort of "ripping ridge on the tank" appeared. Calculations were made that it is more economical to move along ice fields by not pushing over the ice with a further break, but lifting from below. Difference in density of media. (air and water).
Maybe there is something like that. At the level of not a model, but a "prototype". It is very necessary for Russia.

Very touched by the links - as if rejuvenated. Thank.
In business - anyway, a joke. Theoretically, all these ideas have a right to exist, but in reality when confronted with ice, the simpler the design, the less likely it is to break.

[donavi49]

In terms of the main strike weapons, he loses to Burke in whose 96 rocket mines, against 80 in Zumwalt.

The gun has no analogues, but is it really important to have 155 mm PU in real actions? Of course, it’s possible to shoot virtually missiles from the barrel is interesting, but why, if there are VPU mines with more efficient missiles. This is one of the main points of bickering on the project in the US commissions (a lot of money was spent on this innovation, is it really needed? Maybe it’s better to put 2 SPLASHES in their place?).

The destroyer is new, but the main weapons are the same tomahawks ...

What for? So the tomahawks are fine with them at the moment - to defeat a potential enemy. But I am sure that something new is already being prepared for the existing PU. And what to do with the artillery stocks? They have the battleship Missouri hitting Saddam with shells made during World War II. Rich means lean.
On January 7, 1991, at 01:40, two Tomahawk missiles were launched from the Missouri battleship, which had never been launched from a warship of this class for targets located at a distance of 1400 km in Iraq and Kuwait. Initially, the fifty-year sixteen-inch guns fired fiercely. The target was the port of Hanji in Saudi Arabia. When powerful guns began firing every 15 seconds at the Iraqi fortifications, the US Army breathed a sigh of relief - it was a formidable weapon. In two hours, the battleship Missouri fired 135 series of shots. No enemy fire could overtake the battleship. The accuracy of fire control was achieved using unmanned aerial vehicles that were launched from ships using a catapult. They made adjustments to large-caliber fires, then returned, falling into the network. They re-equipped and launched again.
Their computer system was controlled by a pilot from a control point. The received image from the airplane’s video camera was displayed on the internal television system, where the coordinates of the objects were shown. Thanks to the new guidance system, slightly obsolete guns were merciless when hit on target. The combination of new technologies has proven effective. Its volleys in the Persian Gulf became a farewell salute of those times when battleships reigned supreme on the seas and oceans. But the battleship USS Missouri was born at another time.

Otherwise, it is impossible to explain how it exists ... " GOD BLESS RUSSIA!

Do not forget that the main thing on the ship is WEAPONS.

A ship is a complex ergodic object consisting of five main parts ("elements"): crew, hull, weapons, weapons and technical equipment.
Each of these parts can be considered as relatively independent, therefore, the definitions and reasonings set forth above apply to them. As an ergodic object, any warhead of a ship can be considered. Separation of a part of an object from the whole is advisable in solving specific particular problems. For example, the tasks of combat training, including on BZZh.
"Vitality is the ability of a ship to withstand combat and emergency damage, while restoring and maintaining, to the extent possible, its combat capability" (1982). This definition is refined by introducing "survivability elements". Unsinkability is associated with a specific source of damage - the flow of seawater, explosion and fire - with safety, the survivability of weapons and technical equipment is determined directly, other than the survivability of the ship, and the survivability of the crew as a specific organizational structure is reduced to the protection of personnel.

Many people forget about the crew, and without a crew any ship cans.
