USS Zumwalt DDG-1000

US 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.

In this March 21, 2016 file photo, Dave Cleaveland and his son, Cody,
photograph the USS Zumwalt as it passes Fort Popham at the mouth of the
Kennebec River in Phippsburg , Maine , as it heads to sea for final builder
trials. The ship is so stealthy that the U.S. Navy resorted to putting
reflective material on its halyard to make it visible to mariners during
the trials.



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 versions 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 5,400mph 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 navigating 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.



The first ship to be fitted with a Railgun?

A prototype of the BAE railgun which could be fitted to future versions of
the Zumwalt.



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. early in 2016.

Using electromagnetic energy, the gun can fire a shell weighing 10kg at up
to 5,400mph 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 US Navy – one by
British arms manufacturer BAE Systems and the second by a US firm.



Rear Admiral Matthew Klunder, head of US 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
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.

Rear Admiral Matthew Klunder 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.



“It's firing. 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 Defense Initiative, nicknamed 'Star Wars' after the
science fiction film franchise.

never need one again.*
