Corporation employees recently provided X-ray services to
identify artifacts recovered from the wreck of the USS Monitor.
Northrop Grumman's Newport News sector provided the service at the
request of conservators from The Mariners' Museum to help identify a
dozen small artifacts recovered from the Civil War ironclad, which sank
off the coast of Cape Hatteras, N.C. in 1862 and is now protected by a
national marine sanctuary managed by the National Oceanic and
Atmospheric Administration (NOAA).
The equipment used in this effort was a linear accelerator
high-energy X-ray machine. Northrop Grumman Newport News is the only
shipyard to own such a machine, which is normally used to inspect heavy
metallic castings poured in the shipyard's foundry before they are used
for ship construction. Shipyard employees X-rayed artifacts that were
beneath decades of marine growth and encrustation. The X-rays revealed
a shoe, a valve handle, a piece of the Monitor's hull, a piece of chain
and a tread from the engine room floor. "We are happy to be part of
this ongoing project with The Mariners' Museum and NOAA," said Ike
Isenhour, senior project engineer, Newport News Nondestructive Testing
unit, who helped coordinate the X-ray efforts. "As shipbuilders, we
take special pride in helping to preserve such an important part of
Since 2000, Newport News employees have volunteered their help
and expertise to the Monitor recovery project by off-loading artifacts
at shipyard piers and docks, constructing conservation tanks at The
Mariners' Museum, and performing topographical ultrasonic inspections
and X-rays of the recovered items. The Monitor was the U.S. Navy's
first ironclad and is known for its battle with the Confederate
ironclad CSS Virginia, which ended in a draw in Hampton Roads on March
"Northrop Grumman Newport News has played a major role in the
history of The Mariners' Museum. More recently, the company's vital
role in the movement, conservation and exhibition of artifacts from the
Monitor has been both critical and invaluable," said Museum President
and CEO John Hightower. "Northrop Grumman's efforts with The Mariners'
Museum, especially in terms of volunteers in the Apprentice Program and
hosts of other employees, have been extraordinary."
"NOAA and The Mariners' Museum are fortunate to have Northrop
Grumman Newport News for a neighbor and partner," said Dr. John
Broadwater, manager, NOAA Monitor National Marine Sanctuary Program.
"The company's cutting edge technologies and engineering expertise have
been invaluable in the complex process of analyzing Monitor artifacts.
Thanks to their enthusiastic assistance, we have been able to examine
and analyze objects from the Monitor and determine the best methods for
handling and treating those often fragile artifacts to ensure that they
will be preserved for future generations."
Northrop Grumman Newport News, headquartered in Newport News,
Va., is the nation's sole designer, builder, and refueler of
nuclear-powered aircraft carriers and one of only two companies capable
of designing and building nuclear-powered submarines. Newport News also
provides after-market services for a wide array of naval and commercial
vessels. The Newport News sector employs about 18,000 people.
In 1987, The Mariners' Museum was designated by NOAA, on behalf
of the federal government, as the repository for artifacts and archives
from the USS Monitor. Working hand in hand with NOAA and the U.S.
Navy, the museum has received over 1,100 artifacts from the Monitor,
including the steam engine, propeller and revolving gun turret. The
Mariners' Museum is currently underway with a $30 million national
capital campaign to construct the USS Monitor Center addition to the
Museum. With funding from both public and private sources, the Center
will open in 2007. Developed in collaboration with NOAA, the USS
Monitor Center will serve as the definitive national authority and
repository for materials, research and programming related to the
history of the Monitor—and the larger, and lesser known, story of the
naval history of the Civil War.
NOAA's National Marine Sanctuary Program, which manages the
Monitor National Marine Sanctuary, seeks to increase the public
awareness of America's maritime heritage by conducting scientific
research, monitoring, exploration and educational programs. Today, 13
national marine sanctuaries encompass more than 18,000 square miles of
America's ocean and Great Lakes natural and cultural resources.
