Subject: Conversion of USS Georgia From SSBN to SSGN
gf0012-aust    10/17/2005 8:47:13 PM
US Naval Sea Systems Command Mon, 17 Oct 2005, 08:47 The Navy today has awarded General Dynamics Electric Boat (GDEB) a cost reimbursement modification, valued at $162,359,000 for the conversion of the USS Georgia from an Ohio Class ballistic missile submarine (SSBN 729) to Ohio Class guided missile submarine (SSGN 729). ?This contract modification represents the final contractual step in transforming the first four Ohio Class SSBNs into the most capable strike and Special Forces platform in the Navy," said Capt. David Norris, who is the Program Executive Officer, Submarine?s SSGN Program Manager (PMS 398). ?USS Georgia is the last of four ships to enter the conversion phase,? Norris continued, ?and it comes almost one month to the day before Ohio returns to the Fleet as an SSGN.? The USS Georgia's conversion will be conducted concurrently with its Engineered Refueling Overhaul (ERO) work already being performed at Norfolk Naval Shipyard (NNSY). Seventy-seven percent of the ship's conversion work will also be performed at NNSY, with 16 percent of work at Quonset Point, Rhode Island and seven percent in Groton, Connecticut. USS Georgia began its ERO at NNSY in March 2005, and is expected to complete conversion in September 2007. The SSGN program leverages the expertise of private and public shipyards. General Dynamics Electric Boat (GDEB) is responsible for the ship design and conducts and manages the conversions. The Naval Shipyards are conducting the refueling overhauls, providing government furnished services to GDEB, and providing some conversion labor under Centers of Industrial and Technical Excellence agreements with GDEB. Under the direction of PMS 398, the first four Ohio Class submarines, USS Ohio (SSGN 726), USS Michigan (SSGN 727), USS Florida (SSGN 728), and USS Georgia (SSGN 729) are being converted into the new SSGN class. All four submarines in the program are in Naval Shipyards now for overhaul and conversion; specifically, Ohio and Michigan are at Puget Sound Naval Shipyard, and Florida and Georgia are at NNSY. The SSGN program oversees the development and installation of the modifications to the four Ohio Class ballistic missile submarines to provide a conventional strike capability using Tomahawk cruise missiles, as well as the SOF capability. These modifications include integration of the Tactical Tomahawk Weapons Control System and conversion of the existing strategic fire control system to support the launch of Tomahawk Block III and IV missiles. The missiles are housed in a modular Multiple All Up Round Canister subsystem within the submarine missile tubes. The SSGN program is producing important capability on a time-compressed schedule, at about $1 billion per ship. The cost is significantly less than the cost of a new submarine platform. The primary missions of the SSGN will be land attack and Special Operations Forces (SOF) insertion and support. Each of the converted submarines will have the capability to launch up to 154 Tomahawk or Tactical Tomahawk land attack missiles, as well as support enhanced Intelligence, Surveillance, Reconnaissance, and joint special operations. The space capacity of the SSGN provides the room needed for several SOF platoons to train and maintain physical conditioning for a sustained deployment. Clandestine insertion and retrieval of SOF operators via lockout chambers will be enhanced by the ability of the SSGN to host dual Dry Deck Shelters with SEAL Delivery Vehicles and/or the Advanced SEAL Delivery System. "With our rapid design and construction cycle, intelligent use of existing ships and support infrastructure, and unequalled land attack and special operations capabilities, the Ohio Class SSGN program is a major submarine transformation success story. SSGN provides an exceptional capability in the near term for the Global War on Terrorism at an affordable cost," said Norris.

First of I think it's a great idea, since it saves an assload of cash by not actually creating a new class of warship. Secondly, to the post below, Trident Subs don't use plutonium in their reactors. It uses uranium like everything else. Lastly, I think that the fact that this thing could be parked 50 miles offshore and could basically rape a city in about 10 minutes, makes it a better and useable deterrent. Why have the firepower to end mankind when all you need is enough to disable an entire city, and basically trash the command and control abilities they have in a single stroke. I mean like a previous poster said, if this were used on a major US city, it would take out nearly all the major bridges, plus any sort of command structures, or even destroy most of the anti-aircraft ability of a city(I.E. take out all of their radar). That saves a ton of money, as it doesn't require you to use billion dollar aircraft to get the job done.

Um V^2 just so ya know ATK is actually working with the Navy to have those missile tubes on those Ohios also launch medium range SLBMs of a conventional warhead variety. In terms of force projection with the exception of the SEAL delivery issue I think this is a great force projector on par of the arsenal ship concept with few of the drawbacks (stealth for instance is retained because its not on the surface and it can potentially fire outside of enemy waters depending on which block Tomahawk it uses or even if it gets equipped with Harpoons).

Identify a ship of the four who won't have her SLBM tubes extracted in refit please. Then tell me how we'll launch an SLBM without the tubes. Mushrooms only on my pizza, thanks. I mean, I've already demonstrated the Alzheimers in a previous post (more!) ... v^2

Considering the US has fired 1900 Tomahawk cruise missiles since the first Gulf War, and used just over 800 in Operation Iraqi Freedom, these ships represent a better way to use cruise missiles in conflict. During Operation Iraqi Freedom as an example, the Navy launched Tomahawks from 21 ships, 5 of those were submarines. That means 16 surface ships loaded their VLS systems with Tomahawks. While that is no big deal in a conflict against a country like Iraq where there is a very limited air defense requirement, in the future the Navy AEGIS VLS ships will be much less likely to want to carry large numbers of tomahawks, because the MK-41 launcher will likely be loaded with SM-2 Block IV or ESSM AAW missiles. Because the current VLS surface ships are not rearmed at sea, a surface ship that uses up missiles will have to return to port to reload. Had the US had the SSGN during Operation Iraqi Freedom, the 4 subs could have fired over 600 of the estimated 800 tomahawks fired in that entire conflict, or roughly 75% using just 4 ships. That is a major upgrade in my opinion, particularly in future conflicts when the air threat might be higher or the reality surface ships might be denied from getting close enough for a deep strike, against say Russia or China (examples only). Like VV said though, I'll take a wait and see approach to the whole 'special mission' possibility for the ship. It could work out, but probably not where it would be most useful like the Persian Gulf for example, considering the deepest areas in the entire Persian Gulf is actually shallower in total length in ft. of any SSGN, which means against a legitimate ASW threat SSGN deployment in the Gulf would be foolish to say the least.

Are you suggesting that the tubes not converted to use for special ops are being rendered useless for missle launches? I don't believe this is the case and I know there are folks looking at putting in medium range ballistic missles with non-nuclear (conventional) and kinetic heads. There was also talk of being able to launch "mini" satellites for ad hoc low orbit missions. I don't think anything about the changes to the missle tubes of the OHIO SSGNs precludes ballistic weapons.

"Are you suggesting that the tubes not converted to use for special ops are being rendered useless for missle launches? I don't believe this is the case" I was under the clear impression that unassigned specops tubes were still functional. the SLBM tubes are sectioned - not rendered inop AFAIK.

what eaver you put in those "empty" tubes is still subject to start inspection. inop or not.

I said "tubes" when I meant "liners". The liners are pulled from the launch tubes during the SSGN conversion, you may confirm this by searching the Web. The tubes are modified but left in place so the launch deck retains its watertight integrity. I've taken a long nap since I posted here, however, I can almost guarantee repeat performances in the future. From my perspective it's a good thing I can't hear you laugh from where I'm sitting (unless you're that really annoying guy in the cubicle around the corner). v^2

gotcha, no unless you're a truck driver at SWFPAC.
