USS Zumwalt (first stealth destroyer) leaves dry dock

[CAPSLOCKSTUCK]

The first recorded/attempted submarine attack was 240 years ago.

1776, during the Revolutionary War, the American submersible craft Turtle attempts to attach a time bomb to the hull of British Admiral Richard Howe’s flagship Eagle in New York Harbor. It was the first use of a submarine in warfare.

David Bushnell, an American inventor, began building underwater mines while a student at Yale University. Deciding that a submarine would be the best means of delivering his mines in warfare, he built an eight-foot-long wooden submersible that was christened the Turtle for its shape. Large enough to accommodate one operator, the submarine was entirely hand-powered. Lead ballast kept the craft balanced.

I wouldn't call it successful. It was able to attack but it didn't sink any ships.

Wasnt it supposed to have a drill as well so they could sabotage enemy boats too?

This 19th-century diagram shows the side views of Turtle. It incorrectly depicts the propeller as a screw blade; as seen in the replica photographed above and reported by Sergeant Lee, it was a paddle propeller blade

If you look at the picture in post #102, you can see the drill bit at the front-top, with a rope trailing back to the bomb. The idea was to drill into a ship's hull to attach the bomb, then light the fuse and get the hell outta Dodge. It didn't work because the drill was unable to bore into iron-sheathed hull of the HMS Eagle.

iron-sheathed

copper

"copper bottomed"


EDIT

The Welsh city Swansea was nicknamed "Copperopolis" because of the amount of copper produced and supplied to the Royal Navy.

This is a destroyer. What do destroyers hunt?

I'll give you a hint, it starts with an "S" (and is bolded above)

Among other things . . . check out the Battle off Samar during the Battle of Leyte Gulf in 1944:

U.S. ships
6 escort carriers
3 destroyers
4 destroyer escorts
400 aircraft from Taffy 1, 2, 3

Japanese Center Force
4 battleships (including the Yamato)
6 heavy cruisers
2 light cruisers
11 destroyers
30 aircraft (in kamikaze attack)

The U.S. ships got hammered but successfully routed the Japanese attack.

The first successful sub attack was done by the Hunley: http://www.history.com/news/the-hunleys-daring-submarine-mission-150-years-ago

This is my pic... it carries most horrid name up to date given to any kind of device... A midget submarine class and it is called - Biber...

Wasnt the Yamato made in a US shipyard though? I heard that some Japanese boats were before shit went down and the fighting began

 

[ZoneDymo]

but...what is the point? apart from finding a place to spend a lot A LOT of money that probably could have been spend better elsewhere?

No, the Yamato was built in Kure, Hiroshima. Some of the UK-built battleships like Kongo and Fuso were basically rebuilt and upgraded in Japan. The US had built a few cruisers for Japan pre-WW1, but they had all been scrapped by the time WW2 started.

 

[dorsetknob]

fuso the WW1 batleship Class was built by and in Japan
Fuso the Ironclad was british built and scrapped in 1909

D'oh! Name recycling got me there.

It's officially in service now:
http://www.cnn.com/2016/10/15/politics/uss-zumwalt-stealth-destroyer-commissioning/index.html

Among the things that set the Zumwalt apart from its predecessors in the Arleigh Burke-class of destroyers:

-- A larger flight deck that enables operations with new F-35 fighters and MV-22 Osprey tilt-rotor aircraft;

-- Larger vertical launch missile tubes that can fire larger and more advanced land attack and anti-ship missiles;

-- An electrical power system that generates almost as much electricity as the nuclear power plants on aircraft carriers: "The ship can operate all of its systems and still generate enough electricity to power a small town," the Navy says,

-- The ability, with that extra power, to accommodate weapons of the future, such as electronic rail guns and laser.

But for all that, the Navy plans to buy only the three Zumwalt-class destroyers it has on order, down from 32 originally envisioned early in the program.

I have to call bullshit on the third point. Zumwalt has two 35.4 MW gas turbines for propulsion (70.8 MW) and two 3.8 MW (7.6 MW) gas turbines for general power generation. Total: 78.4 MW.

Nimitz-class had two A4W nuclear reactors each producing 100 MW (200 MW total). The Gerald R. Ford-class has two A1B nuclear reactors each producing 300 MW (600 MW total). Even USS Enterprise, the first nuclear aircraft carrier ever (in service 1962-2012), had eight A2W reactors at...well, apparently know one knows. It produces over 204 MW worth of steam though so...probably...a LOT. Uh, huh, Zumwalt power production is not even close. Nuclear simply out-classes everything else...especially considering its size.


It's crazy that they plan to land F-35s on Zumwalt.

I just imagined one painted in yellow and working as a cab... well it totally makes sense now.

 

[FordGT90Concept]

They should do that to Seahawks.

Shhh... there could be some wets from them here... we could get seriously scolded

The US Navy’s largest and most advanced destroyer is equipped with two massive guns that can hit targets from 80 miles away – but it can’t afford the ammunition.

At $800,000 or more per round for each gun, the Navy says the cost is just too high, and is now moving to cancel these projectiles, according to a new report from Defense News.

 

[D007]

With the way WW3 is looking right now.. We might need it..lol

 

[FordGT90Concept]

Never realized it fired smart projectiles. DOD likely just wants to scrap it in favor of railguns where the gun is expensive but the projectiles are cheap.

The most expensive destroyer ever built for the Navy suffered an engineering problem in the Panama Canal and had to be towed to port.

U.S. Third Fleet spokesman Cmdr. Ryan Perry said a vice admiral directed the USS Zumwalt to remain at ex-Naval Station Rodman in Panama to address the issues, which arose on Monday.

USNI News, a publication of the U.S. Naval Institute, reported on its website that the ship was in the canal when it lost propulsion.

'The ship was in the midst of a southbound transit through the canal when it suffered the casualty,' it said.

Crew saw water intrusion in two of the four bearings that connect to Zumwalt's port and starboard Advanced Induction Motors (AIMs) to the drive shafts, a defense official told USNI News on Tuesday.

The AIMs are the massive electrical motors that are driven by the ship's gas turbines and in turn electrically power the ship's systems and drive the shafts.


USNI News also reported that the Zumwalt suffered minor cosmetic damage. The service has narrowed down the likely problem to lube oil coolers leaking.

As a former Tin Can Sailor, the Advanced Gun System is interesting as it only fires guided projectiles.
My ship was involved in the testing of the Dead Eye laser guided projectile, and recall getting very little sleep as we kept docking to take on more ammunition.

Meanwhile in the UK

The Royal British Navy has become but a shell of her former self due to cuts in funding and used as a disposable chess peice in the world of politics after politicians are done with their posturing
