The Honorable Gordon R.
England, Secretary of the Navy,
addresses the employees of Northrop Grumman Newport
News at the keel authentication ceremony for the newest
Virginia-class submarine, Texas (SSN-775). First
Lady
Laura Bush and Chief of Naval Operations ADM Vern
Clark were also in attendance.
As
construction continues on USS Virginia (SSN-774), the next submarine
of her class marked an important construction milestone in a
ceremony 12 July at Northrop Grumman Newport News.
First
Lady Laura Bush authenticated the hull of Texas (SSN-775) by
scrawling her initials in chalk on a steel plate, so they could be
incised with welding rod and affixed to what will be the keel of the
ship. Referring to the advanced design of the Navy's newest class of
fast-attack submarines, Mrs. Bush, the ship's sponsor and a native
of Midland, Texas, smiled and joked that "Texans love to brag -
if something is newer, bigger and better, then it must be from
Texas."
More
than 200 guests, including a large group of shipyard workers,
listened to a host of Navy and political leaders laud the
significant effort already made toward building the ship.
The
First Lady described the submarine's namesake as a land of heroes,
legends, and great adventures. "And Texas is the land of the
cowboy, an all-American fellow who is polite and slow to anger but
who also has an iron fist and steel-toed boots" - attributes
she credited not only to Texans but also to all Americans. "I
believe that spirit will be built into the core of this ship and its
crew," she added. "In the Texas vernacular, this submarine
will be bigger and better than anything, anywhere, and it will be
manned by the heroes and legends of the United States
Navy.

Under an innovative
agreement, Newport News is producing the Virginia-class
submarines as part of a team with Electric Boat. The team is
currently under contract to build the first four submarines of a
class expected to reach 30 ships. This image taken in March 2002
shows sections of the submarines Texas (SSN-775), Hawaii
(SSN-776) and North Carolina (SSN-777) under construction at
Newport News.
The Virginia-class's advanced technology will bring with it an increase
in firepower, maneuverability, and stealth. These submarines are 377
feet long, will be able to stay submerged for up to three months at
a time, and are capable of underwater speeds of more than 25 knots.
They are designed to be multi-mission capable, with the most
advanced levels of stealth and new systems for intelligence
gathering and deploying Naval Special Warfare forces in littoral
areas. The new class also will serve as the stealthy platform of
choice for ISR, strike, covert mining, SOF, ASW, and Anti-Surface
Warfare (ASUW) missions.
"The
keel laying is the first milestone - authenticating the foundation -
of this ship," said Thomas Shievelbein, President, Northrop
Grumman Newport News. "But the real foundation is the
shipbuilders who build it and the men who board it. This is a
celebration of their skills and dedication."
"Four centuries ago, sailors arrived on our shores at Jamestown
seeking freedom," Virginia Governor Mark Warner said.
"Today, our Sailors go around the world to protect
freedom."
Texas,
the second Virginia-class submarine, is under construction within a
cooperative agreement between Northrop Grumman Newport News and
General Dynamics Electric Boat to produce four such platforms, in
coordination with Naval Sea Systems Command's Supervisor of
Shipbuilding, Conversion and Repair, Newport News. Texas' combat
system has already been installed in the Command and Control
Module, and testing is in progress at CCSM Off-hull Assembly and
Test Site (COATS). Meanwhile, construction of Virginia, the lead
ship of the class, is 79-percent complete and on schedule for
delivery to the Navy in June 2004.

The Virginia
class will compose the bulk of the post-688 SSN force. However,
planned build rates will not maintain what the Navy has determined
to be the minimum essential level of SSNs needed to meet future
mission tasking. Program planners have cited evidence that an
insufficient SSN force size carries costs in terms of Indications
and Warning/ISR gaps, engagement opportunities lost, and ASW and
ASUW shortfalls.
Texas
is the 13th submarine to be built in the Northrop Grumman Newport
New s Module Outfitting Facility (MOF). In the 130,000-square-foot
MOF, submarines are constructed on a level platform, not on an
inclined shipway as in years gone by.
Traditionally,
labor, material, and equipment flowed through the shipyard to arrive
at a single production site: the ship on an inclined way. But
construction for Texas has been broken down into two dozen
hull sections and modules, with each portion representing a key
sub-assembly of the submarine's hull or equipment.
Modules
are extensively outfitted and tested "off-hull" before the
individual pieces a re loaded into the open ends of hull sections
and joined to form the ship. This modular construction process is
very similar to working with toy building blocks, but on a gigantic
scale. At Newport News the ground-work for modular construction was
started in the Ring Module Shop, where initial construction of steel
hull sections creates tanks, foundations, and deck assemblies.
Electric
Boat's Quonset Point Facility in Rhode Island also contributes
groundwork for Texas by building hull rings and subsections
outfitted with pipe, machinery, and electrical components. Electric
Boat will send 11 major ship sections to Newport News on an
ocean-going barge called the Sea Shuttle. Some of these modules will
weigh several hundred tons and will ultimately be joined with others
built by Newport News to create the Texas. The modules from
the Ring Module Shop and Electric Boat will be moved to the MOF, a
ten-story building with four large bay doors. Here the work of
thousands of employees comes together as major systems and large
components are systematically installed and outfitted. Systems and
components vary in size - from entire decks and huge condensers to
small electric motors and switches. All arrive at the MOF ready for
installation on the modules and ultimately in the various hull
cylinders.
After
each module is completed and loaded into the hull cylinders,
four-wheel electric transfer cars are rolled under the hull ring's
strongbacks. Hydraulic jacks on the cars lift the large sections of
the ship, which are then wheeled into place and welded together to
form part of the complete hull. After the modules are joined and the
ship's systems are interconnected, transfer cars under the ship's
strongbacks will lift the vessel simultaneously and roll the ship on
rails (at four feet per minute) to the outboard ways for additional
outfitting and testing.
After Texas
is christened in 2004, it will be transported westward to the edge
of the James River and moved onto the yard's 640-foot floating dry
dock. As the ship is transferred from land, the floating dry dock's
onboard computer receives input from load sensors, tide gauges,
vessel position sensors, draft gauges, and tank level sensors to
control 40 onboard ballast tanks so the dock remains level during
the loading process. After Texas is loaded, the floating dry
dock will move to a nearby 70-foot deep basin where the dock will
submerge, and the submarine will float free . Tugboats then will
pull the ship out of the dock and to a pier in the South Yard for
additional testing in preparation for the ship's sea trials and
final delivery to the Navy.
"This
sophisticated new platform provides versatility from the sea to the
littorals," Northrop Grumman Chairman and Chief Executive
Officer Kent Kresa said. "Texas will have an ability to
collaborate with other ships on an unprecedented scale, essential in
missions which will become crucial in a post-9/11
environment."

Virginia construction is
now more than 79% complete,
and delivery is currently on schedule for June 2004.
Senator
John Warner (R-VA), ranking member of the Senate Armed Services
Committee, pointed out that America's security requires transforming
the military to be able to carry out strikes anywhere in the world.
"This Virginia-class is leading the transformation to
meet that requirement, with its stealth capability to go to the far
corners, to deliver special operations forces and to disrupt
command, control, and communications. No longer is a submarine just
for firing torpedoes." But the loudest applause came when Sen.
Warner promised more to come: "We will appropriate money to
build her sister ships and beyond."
Chief of
Naval Operations ADM Vern Clark said the Navy's mission is to take
America's combat power around the globe and take the fight to our
enemies. The future USS Texas, he added, with its awesome
array of combat capabilities, will enable America to
"strengthen the shield of freedom, enabling us to sail where
others fear to go."
"Over
225 years ago, our nation's forefathers established a Navy to
safeguard our economic prosperity and defend our homeland," ADM
Clark said. "The Submarine Force is an essential part of our
strength today. Our submarines control the seas, enabling us to
strike our enemies from there. We're in a global war on terrorism,
and our mission is to keep the enemy on the run. Our enemies in this
global war will never know we're coming until they feel the sting
from America's submarines."
Looking
out toward the shipyard workers in the back of the large
construction facility, ADM Clark made a request: "Build us a
ship that can go in harm's way, because that's what we intend to
do."
"Benjamin
Franklin," Sen. Warner added, "in response to the
question, 'What have you brought forth?' from members of the press
waiting outside the Constitutional Convention in Philadelphia,
answered, 'A republic, if you can keep it.' You have produced a
vessel to make certain we keep our republic."
Texas
is scheduled for delivery to the Navy in 2005.
