Introduction
The introduction of the first nuclear-powered ballistic missile submarine (ship submersible ballistic nuclear, SSBN) in 1959 changed the course of naval doctrine and strategic weapons system (SWS) development during the Cold War. The idea that developed into the modern fleet ballistic missile (FBM) SWSdesigned to fire a submarine-launched ballistic missile (SLBM)is derived from a German invention in the Second World War. Captured Nazi documents reveal the proposal to mount mortar tubes on the deck of a U-boat. The plan was then to fire the mortars while the tubes attached to the U-boats deck were partly submerged. Based on this concept, the present-day SSBN was born.1
The role of the SSBN
SSBNs are designed to have two roles: a strategic nuclear offensive (first strike) role, and a nuclear deterrent role. The SSBN provides a nations most survivable and enduring strategic nuclear offensive capability, which was especially true for the superpowers during the Cold War. Today, it is one of more survivable legs in the triad of strategic nuclear offensive forces of the United States and Russia, because of extended endurance, quieter propulsion, advanced and secure and constant at-sea communications, radar and long-range FBM SWS. In fact, the most modern of todays SSBNs armed with a full complement of SLBMs can be deployed for between 70-120 days at sea, remaining submerged, in any single operational mission. Each ship typically has two fully trained crews on rotation.
The worlds first SSBNs
In December 1959 the worlds first SSBN, USS George Washington, SSBN-598, a George Washington class FBM submarine, was commissioned into the US Navy. The launch of a Polaris A1 SLBM in July 1960 from SSBN-598 was the first from a submerged submarine. On November 15th 1960, SSBN-598 deployed on operational patrol with 16 x 2,200km-range Polaris A1 SLBMs.
The development of the first Soviet FBM submarine started with a governmental order in the early 1950s for the adaptation of a Project 611 (Zulu) diesel-electric submarine, B-611, to be equipped with the D-1 launch system and two 250km-range R-11FM (Scud) missileswhen armed with a nuclear warhead its range is 150km. B-611 received the tactical designation B-62, a Project 611 A (Zulu IV) with a single R-11FM. In September 1955 the first Soviet SLBM was launched from B-62. From 1955-1958 further testing of the D-1 launch system was carried out. In 1959 B-62 was converted to carry out the first underwater missile firing.
The first Soviet SSBN, Project 658 (Hotel I), K-19, was not commissioned until November 1960, however. Project 658 was a modification of the first Soviet nuclear-powered submarine, Project 627 (November). Unlike Project 627, Project 658 was equipped with a missile compartment that had been previously used on the Project 629 (Golf). Project 658 employed the D-2 lunch system and carried three R-13 (SS-N-4 Sark) 550km-range single-stage storable liquid-propellant SLBMs which could only be fired when surfaced. From 1963-1967 the Project 658 SSBNs were upgraded with the D-4 launch system for submerged firing.
Operationally deployed SSBNs in the declared nuclear weapons sates
The five officially recognised nuclear weapons states, which are signatories to the 1970 Nuclear Non-proliferation Treaty (NPT), all deploy SSBNs. France, the Peoples Republic of China and the United Kingdom followed the US and Soviet/Russian lead and have all developed SSBNs as part of their military doctrines to give them strategic nuclear forces and a credible nuclear deterrent.
The United States
As of January 2003 the US Navy, or USN, deployed 15 Ohio class SSBNs with 360 Trident SLBMs with multiple independently targeted re-entry vehicles, or MIRVs. In spring 2003, the Nevada returned to service, increasing the number of operational Ohio to 16. Of the 18 Ohio built, four are slated for conversion to cruise-missile (SSGN) configuration. The Ohio, commissioned in November 1981, is designed for extended deterrent patrols and provides the sea-based leg of the triad of strategic offensive forces. Each Ohio is at sea at least 66% of the time. One combat cycle includes a 70-day patrol and a 25-day transfer period to the second crew and for re-loading supplies. Ohio is powered by one pressurised water reactor (PWR), can dive to 300m, has a speed of 20-25 knots submerged, a displacement of 16,764 tons submerged, a length of 171m and a crew of 155.
12 Ohio class SSBN-734 are deployed with the USNs newest SLBM, the Trident II D5. Each SSBN-734 has 24 three-stage, solid propellant 7,360km-range D5 SLBMs. The D5 Mk-5, deployed in 1990, is downloaded to eight 475-kiloton (kt)-yield MIRVs, whereas the Mk-4, deployed in 1992, is downloaded to eight 100kt- yield MIRVs. Data is not available on the exact deployment of Mk-4/5 warheads.
4 Ohio class SSBN-726 are deployed with the Trident I, the C-4, deployed in 1979. Each SSBN-726 has up to 24 three-stage, solid-fuel 7,360km-range UGM-93 Trident I C4 SLBMs. Each C4 is currently loaded with 6 100kt-yield MIRVs.
Nearly 50% of the USs total strategic warheads are sea-basedafter the Nevada returns to service in 2003, the Ohio boats have a total of 2,884 MIRVs288 D5 with 2,308 100kt-475kt-yield MIRVs and 96 C4 with 564 100kt-yield MIRVs. Although Trident SLBMs have no pre-set targets when each Ohio goes out on patrol, the SSBNs are capable of rapidly targeting their Trident missiles.
The current US administration plans to field 1,700-2,200 operationally deployed strategic warheads by 2012; though the lower number is derived by no longer counting the warheads on SSBNs in overhaul as being operationally deployed. Two Ohio, with 192 warheads each, are usually in overhaul at any given time.
The Russian Federation
As of January 2003, the Russian Navy is thought to have 14 operationally deployed SSBNs with a total of 232 SLBMs containing 1,072 MIRVs. But the Russian Navy is in a serious state of decline and there are serviceability doubts regarding the SSBN fleet. In fact, the bulk of the SSBN fleet is slated for elimination by 2010 and it is likely that Russia will deploy only seven SSBNs (all Delta VI) by then. Still, the primary mission of Russias SSBN fleet is to provide strategic nuclear deterrence and these SSBNs remain the most important (and most survivable) leg of Russias triad of strategic offensive forces.
Russias most modern SSBN, Project 667BDRM (Delta IV), was commissioned in 1986 and is powered by two PWR. It can dive to 400m, has a speed of 22-24 knots submerged, a displacement of 18,200 tons submerged, a length of 167m, a crew of 130 and an endurance of 80 days. Each of the six operational Project 667 is fitted with the D-9RM launch system and carries 16 R-29RM (SS-N-23 Skif) SLBMs. Deployed in 1986, the 8,300km-range three-stage liquid-propellant R-29RM SLBM carries four 100kt-yield MIRVed warheads.
The worlds largest SSBN, Project 941 (Typhoon), was commissioned in December 1981. It has two PWR, can dive to 500m, has a speed of 25-27 knots submerged, a displacement of 33,800 tons submerged, a length of 170-172m, a crew of 150 men and an endurance of 90-120 days. Each of the two operational Project 941s with the D-19 launch system carries 20 R-39 (SS-N-20 Sturgeon) SLBMs. Deployed in 1983, the 10,000km-range three-stage solid-fuel propellant R-39 carries ten 100kt-yield MIRVed warheads. Project 941 does not have to go to sea to launch, as it can fire its salvo of R-39s while tied up at its dock.
Project 667BDR (Delta III) SSBN was commissioned in 1976. It is powered by two PWR, can dive to 400m, has a speed of 22-24 knots submerged, a displacement of 10,600 tons submerged, a length of 155m, a crew of 130 men and an endurance of 80 days. Each of the six Project 667 with the D-9R launch system carry 16 R-29R (SS-N-18 M1 Stingray) SLBMs. Deployed in 1978, the 6,500km-range liquid-propellant R-29R carries three 200kt-yield MIVRed warheads. This is in compliance with the START-1 Treaty.
France
France currently operates four SSBNs in two classes: two Triomphant class and two LInflexible class. Of the SSBNs currently in Frances strategic submarine force FOST, four are always operational and two are at sea. France has 64 SLBMs and 384 MIRVs in 4 SSBNs, each carrying 16 SLBMs with 96 MIRVs.
Triomphant, commissioned in 1997, is powered by one PWR, has a speed of 25 knots submerged, a displacement of 12,640 tons submerged, a length of 138m and a crew of 111 men. Each of the two vessels in this class carries 16 M45 SLBMs. Deployed in 1996, the 6,000km-range three-stage solid-fuel M45 SLBM is loaded with six 150kt TN 75-type MIRVed warheads.
LInflexible, commissioned in 1974, is powered by one PWR, can dive to 250m, has a speed of 25 knots submerged, a displacement of 8,920 tons submerged, a length of 129m and a crew of 114 submariners. Each of the two vessels in this class carries 16 M-4A/B. Deployed in 1985, the 6,000km-range three-stage solid-fuel M4 is loaded with six 150kt TN 71-type MIRVed warheads.
The United Kingdom
The Royal Navys first Vanguard class SSBN, HMS Vanguard, was commissioned in December 1994. Vanguard provides the UKs strategic and sub-strategic nuclear deterrent and forms the cornerstone of UK defence policy.
Each of the UKs four Vanguard class SSBNs currently in service is powered by one PWR, has a displacement of 15,900 tons submerged, a length of 150m and a crew of 135 submariners. Each Vanguard has a16-tube missile compartmentwhich is based on the design of the 24-tube system deployed on the US Navys Ohiofor 16 Trident II D5. The Trident II D5 is a three-stage solid propellant missile with a 7,400km-range and was first deployed on HMS Vanguard in 1994. Each D5 can carry 8-12 MIRVed warheads, although up until 1998 each Vanguard SSBN had a maximum of 96 warheads loaded into 16 D5 SLBMs.
The 1998 Strategic Defence Review (SDR) confirmed that the UKs new nuclear force structure would consist solely of the four Vanguard class SSBN, only one of which is on active patrol duty at any one time. Moreover, D5 took over the sub-strategic role of the WE-177 nuclear-gravity aircraft bomb, as the last WE-177 bombs were dismantled in 1998. By 1998, Trident II became the UKs sole nuclear weapon. As part of the SDRs recommendations, the maximum load of D5 warheads carried on each Vanguard SSBN was reduced from 96 to 48 and each D5 was downloaded to three 100kt-yield MIRVed warheads.
The Peoples Republic of China
Chinas one and only SSBN was commissioned in 1988. It is powered by a single PWR, has a speed of 22 knots submerged, a displacement of 8,000 tons submerged and a length of 120m. The Xia carries 12 JL-1 (CSS-N-3) 1,700km medium-range 200kt-300kt-yield two-stage solid-propellant SLBM, which became fully operational in 1988. It has never sailed outside Chinas territorial waters and presents no credible threat at present to either the USA or Russia.

Russia is formally withdrawing from a landmark environmental agreement that channeled billions in international funding to secure the Soviet nuclear legacy, leaving undone some of the most radioactively dangerous projects and burning one more bridge of potential cooperation with the West.
While Moscow pushes ahead with major oil, gas and mining projects in the Arctic—bringing more pollution to the fragile region—the spoils of these undertakings are sold to fuel Russia’s war economy, Bellona’s Ksenia Vakhrusheva told a side event at the COP 29, now underway in Baku, Azerbaijan.
