USS Georgia (SSGN 729), the fourth and final ship in the
Navy's new class of reconfigured nuclear-powered guided missile
submarines (SSGN), successfully completed sea trials Dec. 11.
The objective of Georgia's sea trials was to ensure that all of the
submarine's systems perform at full capacity before the submarine
rejoined the fleet yesterday.
Georgia and her sister ships, USS Ohio (SSGN 726), USS Michigan (SSGN
727), and USS Florida (SSGN 728), were formerly the first four ships of
the Navy's current class of trident ballistic missile submarines
"Although the SSGNs look almost identical to the 14 SSBNs from the
outside, all four have been so extensively modified that they are a new
class unto themselves, and like any overhauled or new construction
platform, we first reestablish their readiness to rejoin the fleet via a
full set of sea trials," said SSGN Program Manager Capt. Mark Bock.
"Georgia had a very successful conversion process and both the crew and
ship passed with flying colors."
Modifications include preparing Georgia for its new role as a stealthy
strike and Special Operations Forces (SOF) platform. Georgia also
features upgraded intelligence, search, and reconnaissance (ISR)
capabilities, and an improved communications capacity via the new Common
Submarine Radio Room and two high-data rate antennas. Georgia will also
have the capability to deploy with up to 154 Tomahawk cruise missiles
and accommodate up to 66 SOF personnel for extended periods of time to
support sustained special operation campaigns.
Additionally, SSGNs have converted their forward-most missile tubes to
contain lock-out chambers in support of both Seal Delivery Vehicle Dry
Deck Shelter and Advanced SEAL Delivery System
"At the same time Georgia is conducting sea trials," said Bock, "Ohio is
out on its maiden SSGN deployment, making the last couple of months of
2007 very exciting for the program office, the Submarine Force, and the
Despite the SSGN conversion's complexity and condensed timeline, the
SSGN Program Office estimates that it will deliver all four submarines
within 1.1% of the original cost estimate from 2002.
"The SSGN is a 'good news' story because it speaks volumes about our
credibility to the taxpayer as we have proven our ability to work on a
very complicated program within a constrained cost and schedule
framework," said Program Executive Officer for Submarines Rear Adm.
William Hilarides. "Overall, we took 134 months to deliver the four
SSGNs, which is three months longer than we planned in FY02. It's not
perfect, but it's close."
The SSGN program has reached a number of milestones over the past three
months. On Nov. 1, Hilarides certified the Ohio Class SSGNs as reaching
their Initial Operating Capability during a presentation at the Naval
Submarine League's Annual Symposium. Later that month, Michigan
completed the first battery of tests with ASDS. These included mating
the ASDS docking pylons to Michigan's hull and then landing ASDS aboard
the ship. Michigan is scheduled to conduct at-sea testing with ASDS in
early 2008. In October, Ohio departed its homeport of Bangor, Wash.,
for Hawaii to prepare for its first operational deployment. The SSGNs
are designed and built to deploy from their homeports for one-year
intervals with three crew changes conducted in forward areas. Ohio will
remain forward deployed for a full year prior to returning to Bangor,
Wash. When all four ships reach full operating capabilities, the Navy
will have on average 2.7 SSGNs forward deployed at any one time.
