Navy Changes DDG-47
Classification To CG-47
. The Department of the Navy has an-
nounced it is changing the classification of
the DDG-47, a new ship currently under
construction, to CG-47. The ship, which was
originally classified as a guided missile de-
stroyer with the hull number DDG-47, is
being reclassified a guided missile cruiser
with a hull designation of CG-47.
With the unique effectiveness of the
AEGIS system on this class ship, the change
is based on size and armament, since the
CG-47 is comparable to modern cruisers of
the U.S. Navy, allied navies, and the Soviet
navy.
CG-47, the lead ship of this class, is cur-
rently under construction at the Ingalls
Shipbuilding Division of Litton Industries
at Pascagoula, Miss. The ship is scheduled
for delivery in January 1983.

In early January, Marathon Manufactur-
ing Company's Republic of Singapore yard
delivered the first of two jackup rigs or-
dered by the China National Machinery Im-
port and Export Corporation.
The People's Republic of China rig, Pohai
VIII, was originally scheduled for delivery
in March of this year. Gene M. Woodfin,
chairman of the board and chief executive
officer of Marathon Manufacturing Company,
was pleased to announce that the Singapore
yard was able to improve the contracted de-
livery date by almost two months. He said
the sister rig now nearing completion at the
Singapore yard is expected to be delivered
to the Chinese in March.
Mr. Woodfin said that this was Marathon's
first business venture with the People's Re-
public of China, and among the unique fea-
tures of the agreement was that it called for
"turnkey" rig construction. (Turnkey is a
term used in the trade whereby the builder
also provides the drilling equipment, engine
and generator packages, derrick, drawworks,
etc. Normally, these items are selected and
purchased by the rig owner.) Mr. Woodfin
stated that from initial negotiations through
delivery, Marathon's dealings with the Chi-
nese have been a first-class commercial re-
lationship, and we certainly look forward
to additional orders.
Marathon announced the original contract
for the two rigs in May 1978, shortly after
the contract signing in Peking, China.
The Pohai VIII is a Marathon-class 82-
SD-S, shallow-draft, slot-type jackup drilling
rig. It is equipped with 360 feet of leg and
capable of drilling in 250 feet of water to a
drilling depth of 20,000 feet.
Marathon Manufacturing Company, a sub-
sidiary of The Penn Central Corporation, is
a leading manufacturer of mobile offshore
jackup drilling rigs.
