SSGN “Tactical Trident” Subs: Special Forces and Super Strike
In the aftermath of the START-II arms control treaty, some of the USA’s nuclear-powered Ohio Class SSBN nuclear missile submarines were converted to become long range conventional strike and special operations SSGN “Tactical Tridents.” Four ultra-stealthy Ohio-class SSBNs had their 24 Trident II D-5 nuclear ballistic missiles removed. They were replaced with up to 154 Tomahawk cruise missiles, plus space in the sub for 66-102 special forces troops, special attachments for new Advanced SEAL Delivery System (ASDS) or older Seal Delivery Vehicle (SDV) “mini-subs,” and a mission control center. Unmanned Underwater Vehicles, and even UAVs for aerial operations, are expected to become equally important options over the SSGN fleet’s career.
These modifications provide the USA with an impressive and impressively flexible set of conventional firepower, in a survivable and virtually undetectable platform, which can remain on station for very long periods of time. As surveillance-strike complexes make the near-shore more and more hazardous for conventional ships, and the potential dangers posed by small groups continue to rise, America’s converted SSGN submarines will become more and more valuable. This updated, free-to-view article covers their origins and timeline, the key technologies involved, contracts from the program’s inception to the present day, with all 4 submarines back in service.
The US Navy’s New SSGN Platform
These SSBN to SSGN conversions were originally sparked by the 1992 START II Strategic Arms Reduction Treaty, which limited the number of strategic missile submarines to 14 as of the year 2002. Rather than decommissioning the USS Ohio [SSBN 726], USS Michigan [SSBN 727], USS Florida [SSBN 728] and USS Georgia [SSBN 729] Ohio Class submarines, why not change ther mission, and modify them to the “Tactical Trident” Configuration described above? Strong support for this idea was quickly forthcoming from Senators Dodd [D-CT], Inouye [D-HI], Lieberman [D-CT], and Pell [D-RI].
These submarines’ obvious usefulness in the Global War on Terror, and the program’s previous bipartisan popularity, were potent political assets. The US Senate mandated and funded conversion of all 4 Tactical Trident SSGNs in the FY 2002 defense appropriation bill, even though President Bush had requested only enough money to convert 2 subs.
To create a Tactical Trident submarine, 2 of the Ohio Class SSBNs’ 24 large vertical missile launch tubes are converted to lockout chambers, enabling underwater exits from the hull without sinking the submarine. Dedicated accommodations and facilities exist for 66 Special Operations personnel, generally Navy SEALS – though some sources note an upper limit of 102 troops in emergencies.
It was hoped that Advanced SEAL Delivery System (ASDS) mini-subs could also be attached to the top of the SSGN, in order to deliver SEALs or MARSOC members inshore in a dry environment, reducing fatigue. Unfortunately, the ASDS program suffered from serious development problems, and was eventually canceled. ASDS-1 was used until it was destroyed in a shore fire. Unless an alternate system is developed and deployed, existing Seal Delivery Vehicles (SDVs) will remain the mainstay.
Like the new Virginia Class submarines (SSN-744) whose estimated costs range from $1.7-$2.3 billion billion each, these 4 converted SSGNs will extend US special forces’ underwater insertion capability. The decommissioning of the 1960s-vintage Benjamin Franklin Class [SSBN 640] submarines USS James K. Polk [SSN/SSBN 645] in 1999, and USS Kamehameha [SSN/SSBN 642] in 2002, was offset by the subsequent modification of the SSN-688I improved Los Angeles Class subs Charlotte [SSN 766] and Greeneville [SSN 772], and by the capabilities of each Virginia Class submarine. Even so, the sheer number of SSGN troop berths and dedicated facilities will give the new Tactical Trident subs a level of SOF capability and flexibility that will set it apart. Given the new global environment, the lead role that has been assigned to SOCOM for prosecuting the Global War on Terror, and the USA’s increased emphasis on threats and warfare in shallow water and near-shore littoral zones, the SSGNs bring an extremely important capability to the table.
The havoc that 102 Navy SEALs and/or MARSOC Marines can create is not to be underestimated. Nevertheless, the converted subs’ most powerful strike capability still lies in their missiles. That’s where the submarine’s other 22 vertical launch tubes come in to play, thanks to rotary launchers that let each tube fire up to 7 Tomahawk cruise missiles.
BGM-109 Tomahawk missiles have played major roles in U.S. military operations, from Desert Storm through current operations in Iraq and Afghanistan. Flying close to the ground at just under the speed of sound, they can deliver a 1,000 lb. conventional explosive warhead with pinpoint accuracy via GPS/INS and terrain matching navigation. A datalink even allows them to be reprogrammed among any of 15 pre-programmed alternate targets, while still in the air. In the first day of Operation Iraqi Freedom alone, U.S. forces in the Persian Gulf, Red Sea and Mediterranean Sea launched 320 Tomahawks.
JINSA notes that the majority of Tomahawk cruise missiles are currently launched by Navy surface vessels, such as the Ticonderoga Class (CG-47) cruisers and Arleigh Burke Class (DDG-51) destroyers. The later series of Los Angeles Class (SSN-688I) and the newest Virginia Class (SSN-744) attack submarines are armed with 12 dedicated Tomahawk launch tubes each, while earlier Los Angeles boats and the newest Seawolf Class (SSN-21) have to sacrifice some of their stored torpedoes to carry and launch Tomahawks through their torpedo tubes.
Again, numbers matter. The ability to arrive unnoticed with up to 154 long-range land-attack missiles, launch Tomahawks, and then slip away silently beneath the waves, will make the new Tactical Trident SSGNs the US Navy’s premier future strike platform next to its carrier fleet. This Special Forces/Strike Mission flexibility, and the new SSGNs extreme underwater stealth, may even make them more important and useful in a number of future conflict scenarios. Indeed, if anti-shipping missile technologies and related systems continue to advance faster than defensive improvements, the SSGN fleet’s survivability may vault them into the #1 position as America’s primary strike platform, with special emphasis near a number of key global choke points like the Straits of Hormuz, Straits of Malacca, etc.
The last mission of the SSGN fleet will be one of innovation. An August 2003 Seapower article also suggested that these vessels will perform as seagoing test beds for the submarine fleet, trying out new technologies and testing new tactics for other classes of submarines. sub-launched UAVs, UUVs, and other new equipment are likely to see their first testing and live-use trials aboard these ships.
In the past, when trouble struck in a global hotspot, it has been said that one of the first questions an American President asks has been “Where are the carriers?” In future, that question may often change to “Where are the Tactical Tridents?”
SSGN Coversion: Timelines & Program Contractors
An Oct 17/05 General Dynamics press release noted that If all options are exercised and funded, the overall SSGN conversion contract would be worth a total of $1.4 billion. They were.
Naval Technology reported that USS Ohio [SSGN 726] began conversion in November 2002, and would rejoin the fleet in November 2005. Conversion was declared complete on Jan 9/06, and the submarine spent 2006 and part of 2007 in testing and training. Ohio deployed to the Pacific on active operations in 2007, and Jan 11/08 saw the first active crew swap take place in Guam.
USS Florida [SSGN 727] began SSGN conversion in July 2003, and was expected to rejoin the fleet in April 2006. She left the shipyard at Norfolk in April 2007, and participated in at-sea testing before being sent on active missions. She was the 1st Ohio Class SSGN to fire cruise missiles in combat, during 2011 hostilities over Libya.
USS Michigan [SSGN 728] arrived for conversion in February 2004. The contract noted December 2006 as the expected end of construction and beginning of renewed sea trials; a Return to Service ceremony was hosted on June 12/07.
USS Georgia’s [SSBN 729] plan stipulated September 2007 as the expected end of construction and beginning of renewed sea trials, but a May 2007 NAVSEA release would say only “late 2007.” That date, too, appears to have slipped. In the end, the submarine was returned to service on March 28/08.
A passing operational evaluation (OPEVAL) grade appears to have been granted to the new class, leading to full certification for combat operations, and the beginning of a potent new weapon for American seapower.
With respect to key contractors:
- General Dynamics Electric Boat Corp. was the shipbuilding contractor, and is the default contract recipient in the lists below unless otherwise specified.
- General Dynamics Advanced Information Systems modified the Trident nuclear missile fire control system to systems designed to control Tomahawk cruise missiles etc.
- Northrop Grumman Electronic Systems adapted the ballistic missile missile launch tubes, developing a Multiple All Up Round Canister (MAC) to store and launch of up to 7 TLAM C-E non-nuclear Tomahawk missiles from each of the submarine’s 22 remaining active missile tubes.
- Raytheon builds the Composite Capsule Launching System that helps turn the submarines’ ballistic missile launching tubes into multiple-shot cruise missile launchers. They are also responsible for the submarines’ AN/BYG-1 combat system.
- Northrop Grumman Oceanic and Naval Systems tried to build the attached ASDS “Advanced SEAL delivery System” mini-subs, the successors to the existing SDVs (SEAL Delivery Vehicle). The ASDS aimed to deliver up to 16 Navy SEALs or MARSOC members. Unfortunately the program was not successful.
SSGN Tactical Trident: Contracts and Key Events
Unless otherwise specified, contracts are awarded to General Dynamics Electric Boat Corp. in Groton, CT, by the Naval Sea Systems Command in Washington, DC.
The Virginia Class Block III bow already uses 2 large “six-shooter” rotating tubes, for storing BGM-109 Tomahawk cruise missiles and compatible payloads. Their system is derived from the Ohio SSGNs, but the tubes are a bit shallower and narrower, due to the SSN’s smaller size. The new Virginia design they’re investigating would add a 94-foot section behind the sail, hosting 4 full Trident size “7-shooter” tubes, and bringing the submarines up to 40 cruise missiles each. That’s much smaller than the SSGNs’ 154 launcher maximum, but a fleet of 10 or so boats could be in many more places than a fleet of 4. The Virginia Class can already launch special forces, and can be fitted with adapters to mount underwater special forces vehicles. AOL Defence | Aviation Week | StrategyPage.
March 19/11: Combat Debut. The USS Florida [SSGN 727] fires most of Operation Odyssey Dawn’s initial wave of Tomahawk missiles, as combat over Libya begins. It represents the 1st combat firing of tomahawks by an Ohio Class SSGN – though it may or may not have been the first time an SSGN was used in a combat operation. King’s Bay Periscope.
July 8/10: The US Navy almost never publicizes the activities or locations of its SSBN nuclear missile submarines, beyond the occasional at-sea or home port photo. Now that the converted SSGNs aren’t carrying enough nuclear warheads to end a civilization, however, American naval diplomacy has some additional options in this area. South Korea’s Chosun Ilbo takes notice of publicly-released US Navy pictures of the USS Michigan, docked at South Korea’s Busan naval base over the last week following joint exercises with the ROK Navy. The move comes after China’s proxy North Korea sank the South Korean corvette Cheonan with a submarine-fired torpedo. The paper adds:
“Hong Kong’s South China Morning Post on Sunday said the nuclear-powered [SSGN] submarines Michigan, Ohio and Florida surfaced in Busan, Subic Bay in the Philippines and Diego Garcia in the Indian Ocean around the same time… The sub can also carry South Korean special forces troops for infiltration operations into North Korea in the event that a regime collapse in the North heightens the chances of nuclear weapons and missile theft or a full-blown war. The submarine apparently took part in joint military exercises with South Korea in the past carrying the South’s special forces units.”
June 9 – June 28/10: USS Florida [SSGN 728] makes a scheduled port visit to Diego Garcia in the central Indian Ocean, to undergo routine maintenance and make a scheduled crew swap. The submarine conducted a fast checkout cruise in Diego Garcia after the crew exchange, then left following the 1st voyage repair period of her 2nd deployment. US Navy arrival | departure.
June 24/10: The US Navy releases a photo of USS Ohio Gold Crew commander Capt. Dixon Hicks, explaining basic operations of the Dry Dock Shelter and Seal Delivery Vehicles to visiting Filipino security officials during a routine port visit to Subic Bay.
Subic Bay was once an American naval station, but is now simply a foreign port. Even so, it’s more than just a waypoint. The Philippines have a long-running Islamist insurgency in their southern islands, which has been a focus for a lot of work by American special forces in recent years.
March 9/10: USS Florida [SSGN 728] arrives for a routine port visit to the island of Crete, in the eastern Mediterranean Sea. US Navy.
Aug 29/09: USS Ohio [SSGN 726] arrives at Fleet Activities Yokosuka in Japan for a routine port visit. The visit to Yokosuka marks the beginning of a one-year deployment to U.S. 7th Fleet for Ohio. US Navy.
Aug 5/09: A US Navy photo and caption offer a glimpse into the SSGNs’ work:
“The guided-missile submarine USS Georgia (SSGN 729) transits the St. Marys River on her first operational deployment as a converted Guided-missile submarine. Georgia will deploy for approximately one year to the 5th and 6th Fleet areas of responsibility before returning to homeport at Naval Submarine Base Kings Bay, Ga.”
Oct 27/08: Information Dissemination relays a Defense Daily report quoting The Director of the new US Navy Irregular Warfare Office, Rear Adm. (sel.) Mark Kenny. He apparently told the Submarine Naval League Symposium in Virginia:
“The first two deployments, the Ohio and Florida, were groundbreaking deployments… The ships work as advertised, brought home the bacon. And I wish I could give you the briefs in detail, because they are eye-watering… These ships are the Navy’s premiere counter-terrorism tool, no doubt about it.”
Feb 22/08: StrategyPage reports that “The U.S. Navy has completed the conversion of the last of four Ohio class ballistic missile submarines (SSBNs), to cruise missile submarines (SSGN).”
Jan 10/08: The US military no longer sails its ships home every time it needs to swap crews – instead, it brings new crews to the ships. USS Ohio [SSGN 726] is completing the first underway period of a 1 year deployment to 7th Fleet, and is spending its time in the Western Pacific. On this day, the submarine arrived in Guam. Its original “Blue Crew” was relieved on Jan 11/08 by the follow-on “Gold Crew,” but will remain for about 3 weeks to put the sub in tip-top shape before they fully turn it over and fly home.
Ohio will treat Guam as its home base until have 3 crew swaps have passed; then it will return to its official home port in Bangor, WA. US Navy release.

Feb 7/06: USS Ohio (now SSGN 726), the first of four SSGNs, rejoins the fleet in a return to service ceremony at Naval Base Kitsap-Bangor, WA. See US Navy release.
Jan 9/06: General Dynamics Electric Boat completes its conversion of USS Ohio [SSBN 726], the first of four Ohio-class submarines to be reconfigured. EB President John Casey noted that the conversion – comprising design, manufacturing, installation and at-sea testing – was completed only three years after the Navy decided to move forward with the program (DID: 3 years for the sub from Dec. 18/03, but it’s 4 for the program). “That’s a remarkable achievement,” he said.
He also said that USS Florida is on track to follow the lead-ship sea trial by only 3 months, which would result in delivery of the 2nd SSGN over a shorter-than-normal timeframe, and at a conversion cost lower than the lead ship’s. Read the GDEB corporate release.
Dec 19/05: The USS Ohio takes a significant step towards rejoining the fleet when it arrived at Puget Sound Naval Shipyard and Intermediate Maintenance Facility, Bremerton, WA with a broom atop its sail – signifying a clean sweep of its initial sea trials. US Navy photo.

Jan 11/08: A ribbon-cutting ceremony marks the completion of upgrades to Bravo Wharf at Naval Base Guam, providing the capability to host the Navy’s new SSGN submarines. The $50.7 million military construction (MILCON) project was awarded to Black Construction Corp. in 2006, and entailed dredging of the channel and turn basin at inner Apra Harbor, strengthening of existing wharf foundations, extending the wharf to accommodate SSGNs, as well as upgrading the fire protection, lighting, anchoring and water distribution systems. The newly improved wharf can also accommodate ships as large as a CG-47 Ticonderoga class cruisers.
The capability to host and provide a complete range of shore services to the SSGN on Guam allows for longer-term submarine presence, as well as a more robust range of sub-surface mission packages available in the Pacific theater of operations.

Note that US and British special forces have been used in the past to target the cocaine cartels’ operations.

Between 2000 and 2007, only 23 of these boats were spotted. But last year, over 70 were detected or captured… Many of the captures are the result of intelligence information at the source, not air and naval patrols… It’s estimated that about 75 of these subs are being built in northwest Colombia each year, and sent on one way trips north. Each of these boats carries a four man crew and about seven tons of cocaine (worth nearly $200 million on the street).”
