    U. S. Navy's giant new destroyer is TOO stealthy: Zumwalt to be fitted with reflectors so other ships can spot it at sea


    The future USS Zumwalt is so stealthy that it'll go to sea with reflective material that can be hoisted to make it more visible to other ships.

    The Navy destroyer is designed to look like a much smaller vessel on radar, and it lived up to its billing during recent builder trials. Lawrence Pye, a lobsterman, told The Associated Press that on his radar screen the 610-foot ship looked like a 40- to 50-foot fishing boat.

    He watched as the behemoth came within a half-mile while returning to shipbuilder Bath Iron Works.

    'It's pretty mammoth when it's that close to you,' Pye said.

    Despite its size, the warship is 50 times harder to detect than current destroyers, thanks to its angular shape and other design features; and its stealth could improve even more, once testing equipment is removed, said Capt. James Downey, program manager. During sea trials last month, the Navy tested Zumwalt's radar signature with and without reflective material hoisted on its halyard, he said. The goal was to get a better idea of exactly how stealthy the ship really is, Downey said from Washington, D.C.

    The reflectors, which look like metal cylinders, have been used on other warships, and will be standard issue on the Zumwalt and two sister ships, for times when stealth becomes a liability and they want to be visible on radar, like times of fog or heavy ship traffic, he said.

    The possibility of a collision is remote. The Zumwalt has sophisticated radar to detect vessels from miles away, allowing plenty of time for evasive action. But there is a concern that civilian mariners might not see it during bad weather or at night, and the reflective material could save them from being startled.

    The destroyer is unlike anything ever built for the Navy. Besides a shape designed to deflect enemy radar, it features a wave-piercing 'tumblehome' hull, composite deckhouse, electric propulsion and new guns.

    More tests will be conducted when the ship returns to sea later this month for final trials before being delivered to the Navy. The warship is due to be commissioned in October in Baltimore, and will undergo more testing before becoming fully operational in 2018.

    Future version of the radical design are expected to be used to test a futuristic 'Star Wars' railgun, that uses electromagnetic energy to fire a shell weighing 10kg at up to 5,400 mph over 100 miles, with such force and accuracy it penetrates three concrete walls or six half-inch thick steel plates.


    The largest destroyer ever built for the U. S. Navy is currently undergoing sea trials.

    Future versions of the radical design will be fitted with 'star wars' railguns, if tests go according to plan.

    More than 200 shipbuilders, sailors, and residents gathered to watch as the futuristic 600-foot, 15,000-ton USS Zumwalt glided past Fort Popham, accompanied by tugboats on Monday.

    The $4.3bn ship departed from shipbuilder Bath Iron Works in Maine and carefully navigated the winding Kennebec River before reaching the open ocean, where the ship will undergo sea trials.

    Kelley Campana, a Bath Iron Works employee, said she had goose bumps and tears in her eyes.

    'This is pretty exciting. It's a great day to be a shipbuilder and to be an American,' she said.

    'It's the first in its class. There's never been anything like it. It looks like the future.'

    Larry Harris, a retired Raytheon employee who worked on the ship, watched it depart from Bath.

    'It's as cool as can be. It's nice to see it underway,' he said. 'Hopefully, it will perform as advertised.'

    Bath Iron Works will be testing the ship's performance and making tweaks this winter.

    For the crew and all those involved in designing, building, and readying this fantastic ship, this is a huge milestone,' the ship's skipper, Navy Capt. James Kirk, said before the ship departed.

    Advanced automation will allow the warship to operate with a much smaller crew size than current destroyers.


    Future versions of the radical design are expected to be used to test a futuristic 'Star Wars' railgun (advanced gun system) that uses electromagnetic energy to fire a shell weighing 10kg at up to 5,400mph over 100 miles.

    The ship has electric propulsion, new radar and sonar, powerful missiles and guns, and a stealthy design to reduce its radar signature. Advanced automation will allow the warship to operate with a much smaller crew size than current destroyers.

    All of that innovation has led to construction delays and a growing price tag. The Zumwalt, the first of three ships in the class, will cost at least $4.4 billion.

    The ship looks like nothing ever built at Bath Iron Works. The inverse bow juts forward to slice through the waves. Sharp angles deflect enemy radar signals. Radar and antennas are hidden in a composite deckhouse.

    Described as 'Star Wars technology' by researchers, the railgun can fire shells at seven times speed of sound, and penetrate concrete 100 miles away.

    The weapon was on display to the public for the first time at the Naval Future Force Science and Technology EXPO at the Walter E. Washington Convention Center in Washington, D.C. earlier this year. Using electromagnetic energy, the gun can fire a shell weighing 10 kg at up to 5,400 mph over 100 miles with such force and accuracy it penetrates three concrete walls or six half-inch thick steel plates.

    Two prototypes of the weapon have been developed for the U. S. Navy, one by British arms manufacturer BAE Systems and the second by a U. S. firm.

    Rear Admiral Matthew Klunder, head of U. S. Naval Research, has previously said the futuristic electromagnetic railgun, so-called because it fires from two parallel rails, had already undergone extensive testing on land. It will eventually be mounted on the third Zumwalt-class ship.

    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.

    'An electromagnetic railgun is a gun that uses just electricity, no gun powder, and can shoot a projectile well over 100 miles at Mach 7. Energetic weapons, such as EM railguns, are the future of naval combat.'

    Electromagnetic launchers were one of the areas researched by Ronald Reagan's Strategic Defence Initiative, nicknamed 'Star Wars' after the science fiction film franchise.

    U. S. Navy to deploy prototype RAILGUN aboard ships

    The builder's sea trials will answer any questions of seaworthiness for a ship that utilizes a type of hull associated with pre-dreadnought battleships from a century ago. Critics say the 'tumblehome' hull's sloping shape makes it less stable than conventional hulls, but it contributes to the ship's stealth, and the Navy is confident in the design.

    Eric Wertheim, author and editor of the U. S. Naval Institute's 'Guide to Combat Fleets of the World,' said there's no question the integration of so many new systems--from the electric drive to the tumblehome hull-- carries some level of risk. Operational concerns, growing costs, and fleet makeup led the Navy to truncate the 32-ship program to three ships, he said. With only three ships, the class of destroyers could become something of a technology demonstration project, he said.

    70–100 LRLAP rounds planned as of 2005 of total

    Two × Mk 110 57 mm gun (CIGS)


    The Zumwalt looks like no other U. S. warship, with an angular profile and clean carbon fiber superstructure that hides antennas and radar masts, among many other features

    The goal is to deliver it to the Navy sometime next year. 'We are absolutely fired up to see Zumwalt get underway.

    Originally envisioned as a 'stealth destroyer,' the Zumwalt has a low-slung appearance and angles that deflect radar. Its wave-piercing hull aims for a smoother ride.

    She is a POS! Dad was involved with early trials, and she is so prone to failures, and even worse, rough water handling is awful. they canceled the series! She will thankfully be a one off!

    Hmm. Saw an article on the rail gun that they want to install on the 3rd of the series.

    Programs come. Programs go.

    Navy considers railgun for a Zumwalt-class destroyer (http://www.militarytimes.com/story/military/tech/2016/02/14/navy-considers-railgun-zumwalt-class-destroyer/80374120/)

    "Adm. Pete Fanta, the Navy's director of surface warfare, has floated the idea of foregoing the current plan to put a prototype on another vessel this year and instead put it directly on future USS Lyndon B. Johnson, though no final decision has been made.

    There has been talk since the inception of the Zumwalt program that the massive destroyers would be a likely candidate for the weapon because of its power plant. The USS Johnson will be the third and final destroyer in the Zumwalt class. "

    Yea, I see they keep going back and forth with plans to build more. If they do, hopefully they will fix the problems! Last I saw, the Railgun was to be mounted on one of the U.S.M.C. landing ships for trials! I also see the NAVY is planning to build More Littoral Class ships from Corvette through Destroyer! From what I have been hearing through those in the know in the NAVY, this would be the New Navy, and the removal of the Cruiser class in favor of heavy destroyers, as the main surface force in support of the battle groups, and the Littoral classes for every thing else! They also expanded the motor gunboat program (U.S.S. Firebolt) to include several more, and additional designs to be submitted!

    So if it cost each one of us $ 13.00, does that include the bribes, graft, payola, vote buying, congressional influence peddling, and all the other assorted crap that really drives this complete waste of money ??
