Newport News Shipbuilding has
been awarded a $2.9-billion modifi-
cation to an existing contract to pro-
vide for the construction of two
Nimitz Class aircraft carriers. The
total target price for the construc-
tion, including the original contract
award of $724 million, amounts to
nearly $3.7 billion.
The earlier contract, signed in
March, was for the designing and
planning for construction of the two
new aircraft carriers and for pur-
chase of long lead time materials.
Together with the $612-million
Navy contract awarded to Newport
News for two Los Angeles Class
attack submarines, this award raises
the shipyard's backlog to $8.7 mil-
lion.
Edward J. Campbell, presi-
dent and chief executive officer of
Newport News Shipbuilding, said:
"We are most pleased with this
award. It will enable our trained and
experienced carrier construction
work force to go from one ship to the
next without interruption, allowing
us to build them in the most cost-
efficient manner. This award, along
with current submarine construc-
tion contracts, will ensure continua-
tion of stable employment at the
shipyard for the next several
years."
The two new Nimitz Class air-
craft carriers are designated CVN
74 and CVN 75. CVN 74 is sched-
uled for delivery in 1996, and CVN
75 in 1998. When christened, CVN
74 will be named the John C. Sten-
nis.
Newport News Shipbuilding is
also currently building two other
Nimitz Class carriers, the Abraham
Lincoln (CVN 72) and the George
Washington (CVN 73), and has con-
tracts for the construction of 11 Los
Angeles Class attack submarines.

One of the largest passenger ex-
cursion boats built this year has
been put into service powered by a
trio of 500-horsepower Cummins
KTA-19 engines. The vessel sails on
all-day excursion trips between
South Charleston, W. Va., and Hun-
tington, W. Va.
Appropriately named the West
Virginia Belle, this vessel is the lat-
est addition in owner Bob Kehl's
fleet. Mr. Kehl owns Robert's River
Rides, which operates three other
excursion/dinner boats on the Mis-
sissippi River in the Quad Cities,
Dubuque and Bettendorf areas of
Iowa and Illinois.
By any standards, the West Vir-
ginia Belle is simply spectacular.
Built by Patti Shipyards, Inc., Pen-
sacola, Fla., and designed by their
own in-house architectural staff, the
West Virginia Belle measures 197
feet 9 inches by 46 feet with a 10-
foot draft. She features two totally
enclosed decks, a partially enclosed
third deck, and an open fourth deck
topped by a pilothouse. Although
the boat will be certified for at least
1,200 passengers, Mr. Kehl will lim-
it capacity to 1,000 on all-day 100-
mile trips.
While the KTA-19 engines are
one of the standard workhorses of
the Cummins marine diesel line, the
propulsion system aboard the West
Virginia Belle is unique.
For example, the Columbian Ka-
plan-style propellers are enclosed in
Padget-Swann kort nozzles. "That's
a first for passenger excursion ves-
sels as far as we are concerned," said
Frank Patti, owner of Patti Ship-
yard.
Another important aspect of the
propulsion system is its vibration
isolation system, supplied by Lo Rez
Vibration Control, British Colum-
bia, Canada. This system provides
an effective isolation system for en-
gine-sourced vibration in medium-
and high-speed marine engines, re-
ducing noise by 90 percent over the
entire speed range of the engine. It
was custom designed for this appli-
cation by Lo Rez working with the
Patti design staff and Cummins en-
gineering.

"We have used similar isolation
systems on smaller horsepower en-
gines before," said Dave Adams of
Cummins engineering department.
"But, this is the first installation we
know of on engines in the 500 horse-
power range."
Two additional Cummins engines
are located far forward to power a
pair of 250-kw gensets. Cummins
NT855 models were chosen for this
job. All five Cummins engines were
sold by Northern Iowa Diesel, Du-
buque, Iowa.
The hydraulic system onboard
the boat was supplied by Custom
Hydraulics, Gretna, La. A PTO, at-
tached to one of the gensets, runs a
hydraulic pump that powers the
bowthruster. Separate electric mo-
tors powering hydraulic pumps op-
erate the steering system, and the
paddlewheel lifting system. The
West Virginia Belle has a cosmetic
paddlewheel that can be lifted out
of the water to cut drag during times
when the boat is underway at full
speed.
Among the state-of-the-art sys-
tems onboard the riverboat are an
eight station TV monitoring system,
centralized liquor dispensing, elec-
tronic engine controls with five con-
trol stations, three Microphor sew-
age treatment systems and an Aqua-
fine ultraviolet water purifier.
