{{Short description|Soviet ballistic missile submarine class}}
'''''Yankee I''-class submarines''' (often just '''''Yankee''-class''') are nuclear-powered [[submarines]] that were originally constructed by the [[Soviet Union]]. They were the first class of Soviet subs to have comparable firepower, in terms of [[ballistic missile]] batteries, to their [[United States|American]] counterparts. ''Yankee'' subs were quieter than their [[Hotel class|''Hotel''-class]] predecessors and had smoother lines that made them more efficient in the water. The ships were armed with 16 ballistic missiles during the [[Cold War]], although the [[START II]] treaty has meant that most of the ships have been decommissioned. The two that remain have seen their missile complements reduced.

The '''''Yankee'' class''', [[List of ships of Russia by project number|Soviet designations]] '''Project 667A ''Navaga''''' ([[navaga]]) and '''Project 667AU ''Nalim''''' ([[burbot]]) for the [[Initial operating capability|basic]] '''''Yankee''-I''', were a family of [[Nuclear propulsion|nuclear-powered]] [[ballistic missile submarine]]s built in the [[Soviet Union]] for the [[Soviet Navy]]. In total, 34 units were built: 24 in [[Severodvinsk]] for the [[Northern Fleet]] and the remaining 10 in [[Komsomolsk-on-Amur]] for the [[Pacific Fleet (Russia)|Pacific Fleet]]. Two Northern Fleet units were later transferred to the Pacific.
==General characteristics==

*Length: 128.0 m (420 feet)
The ''Yankee''-class were subject to a [[#Variants|wide variety of modifications]]; these ships have a different designation to the original model.
*Beam: 11.7 m (38 feet)

*Draught: 9 m (29 feet)
==Design==
*Displacement: 7,760/11,500 tonnes
The Yankee-class [[nuclear submarine]]s were the first class of [[Soviet Union|Soviet]] [[ballistic missile submarine]]s (SSBN) to have [[thermonuclear]] firepower comparable with that of their American and British [[Polaris missile|Polaris submarine]] counterparts. The Yankee class were quieter in the ocean than were their {{sclass2|Hotel|submarine|0}} predecessors, and had better [[drag (physics)|streamlining]] that improved their underwater performance. The Yankee class were actually quite similar to the Polaris submarines of the [[U.S. Navy]] and the [[Royal Navy]]. These boats were all armed with 16 [[submarine-launched ballistic missile]]s (SLBM) with multiple [[nuclear warhead]]s as [[nuclear deterrent]]s during the [[Cold War]], and their [[ballistic missile]]s had ranges from {{convert|1500|-|2500|nmi|lk=in}}.

== Operational history ==
[[File:Submarine Yankee I damaged.jpg|thumb|left|''K-219'' damaged]]
The Yankee-class SSBNs served in the [[Soviet Navy]] in three oceans: the [[Atlantic Ocean]], the [[Pacific Ocean]], and the [[Arctic Ocean]] beginning in the 1960s. During the 1970s about three Yankee-class were continually on patrol in a so-called "patrol box" in the Atlantic Ocean just east of [[Bermuda]]<ref>{{cite news|url=http://www.theroyalgazette.com/apps/pbcs.dll/article?AID=/20051230/MIDOCEAN/112300121 |title=Title unknown |newspaper=[[The Royal Gazette (Bermuda)|The Royal Gazette]] |url-status=dead |archive-url=https://web.archive.org/web/20060329044818/http://www.theroyalgazette.com/apps/pbcs.dll/article?AID=/20051230/MIDOCEAN/112300121 |archive-date=March 29, 2006 }}</ref> and off the [[United States West Coast|US Pacific coast]]. This forward deployment of the SSBNs was seen to balance the presence of American, British, and [[France|French]] nuclear weapons kept in [[Western Europe]] and on [[warship]]s (including nuclear submarines) in the surrounding Atlantic Ocean, including the [[Mediterranean Sea]] and the [[Atlantic Ocean|Eastern Atlantic]].

The lead boat K-137 ''[[Vladimir_Lenin#Legacy|Leninets]]'' received its [[honorific name]] on 11 April 1970, two and one half years after being commissioned.

One Yankee-class submarine, {{ship|Soviet submarine|K-219||2}}, was lost on 6 October 1986 after an explosion and fire on board. This boat had been at sea near Bermuda, and she sank from loss of [[buoyancy]] because of flooding. Four of her sailors died before rescue ships arrived. The events surrounding the loss of this boat has continued to be [[controversial]].

At least one other boat in this class was involved in a collision with a U.S. Navy nuclear submarine.{{Citation needed|reason=very strong source required|date=March 2019}}

Because of their [[Obsolescence|increasing age]], and as negotiated in the [[SALT|SALT I]], [[START I]] and [[START II]] treaties that reduce [[nuclear armament]]s of the United States and the Soviet Union, all boats of Yankee class were disarmed, [[ship decommissioning|decommissioned]] and sent to the [[Ship-Submarine Recycling Program|nuclear ship scrapyard]]s.

== Variants ==
There were eight different versions of the ''Yankee''-class submarines:

In [[Tom Clancy]]'s 1986 techno-thriller [[Red Storm Rising]], the entire Yankee-class of [[SSBN]]s are proposed to be taken out of service and scrapped by the [[Soviet Union]] as part of the [[Maskirovka]] I, in part to have the [[United States]] to do likewise with its own first-generation [[George Washington class]], [[Ethan Allen-class submarine|Ethan Allen class]] and [[Lafayette-class submarine|Lafayette class]] SSBNs, and allay [[NATO]] misgivings of the [[USSR]]'s intentions.

The Yankee class, Soviet designations Project 667A Navaga (navaga) and Project 667AU Nalim (burbot) for the basic Yankee-I, were a family of nuclear-powered ballistic missile submarines built in the Soviet Union for the Soviet Navy. In total, 34 units were built: 24 in Severodvinsk for the Northern Fleet and the remaining 10 in Komsomolsk-on-Amur for the Pacific Fleet. Two Northern Fleet units were later transferred to the Pacific.

The Yankee-class were subject to a wide variety of modifications; these ships have a different designation to the original model.

Design

[edit]

The Yankee-class nuclear submarines were the first class of Soviet ballistic missile submarines (SSBN) to have thermonuclear firepower comparable with that of their American and British Polaris submarine counterparts. The Yankee class were quieter in the ocean than were their Hotel-class predecessors, and had better streamlining that improved their underwater performance. The Yankee class were actually quite similar to the Polaris submarines of the U.S. Navy and the Royal Navy. These boats were all armed with 16 submarine-launched ballistic missiles (SLBM) with multiple nuclear warheads as nuclear deterrents during the Cold War, and their ballistic missiles had ranges from 1,500–2,500 nautical miles (2,800–4,600 km; 1,700–2,900 mi).

Operational history

[edit]
K-219 damaged

The Yankee-class SSBNs served in the Soviet Navy in three oceans: the Atlantic Ocean, the Pacific Ocean, and the Arctic Ocean beginning in the 1960s. During the 1970s about three Yankee-class were continually on patrol in a so-called "patrol box" in the Atlantic Ocean just east of Bermuda[1] and off the US Pacific coast. This forward deployment of the SSBNs was seen to balance the presence of American, British, and French nuclear weapons kept in Western Europe and on warships (including nuclear submarines) in the surrounding Atlantic Ocean, including the Mediterranean Sea and the Eastern Atlantic.

The lead boat K-137 Leninets received its honorific name on 11 April 1970, two and one half years after being commissioned.

One Yankee-class submarine, K-219, was lost on 6 October 1986 after an explosion and fire on board. This boat had been at sea near Bermuda, and she sank from loss of buoyancy because of flooding. Four of her sailors died before rescue ships arrived. The events surrounding the loss of this boat has continued to be controversial.

At least one other boat in this class was involved in a collision with a U.S. Navy nuclear submarine.[citation needed]

Because of their increasing age, and as negotiated in the SALT I, START I and START II treaties that reduce nuclear armaments of the United States and the Soviet Union, all boats of Yankee class were disarmed, decommissioned and sent to the nuclear ship scrapyards.

Variants

[edit]

There were eight different versions of the Yankee-class submarines:

Yankee-class submarines[2]
First entered Service NATO reporting name Project Name and Number Image Class Main Payload Numbers built Notes
1967 Yankee-I 667А "Навага" SSBN 16 x Р-27 Зыбь 34 Baseline; first Soviet sub to carry SLBMs in hull, as opposed to the sail. Some were later disarmed and operated as SSNs; sometimes classed as SSNX
1975 Improved Yankee-I 667АУ "Налим" SSBN 16 x Р-27У 13 converted У/U for Improved (Russian: Улучшен; Uluchshen)
1977 Yankee-II 667АМ "Навага-М" SSBN 12 x Р-31 1 converted First Soviet sub to carry solid-fueled SLBMs. Subsequently theorized as emergency satellite-launcher or to strike ships in aircraft carrier battle groups
1987 Yankee Notch 667АТ "Груша" SSGN/SSN 32-40 x РК-55 Гранат (SS-N-21 Sampson) 3 converted + 4 unfinished Lengthened by 12 metres (39.4 ft) to 141.5 m (464 ft); 8 more torpedo tubes in waist
1989 (program cancelled) Yankee Sidecar 667М "Андромеда" SSGN 12 x П-750 Метеорит (SS-NX-24 Scorpion) 1 converted Delivered as an attack sub due to missile program cancellation. 153 m (502 ft) long, 13,650 tons full displacement
1984 Yankee Pod 667АК "Аксон-1" SSAN Towed array sonar, pod, other sensor systems 1 converted K-403 Kazan. The tailfin-pod is similar to those of the Щука- and Щука-Б SSNs
1996 Yankee Big Nose 09780 "Аксон-2" SSAN Towed array sonar, Irtysh-Amphora spherical sonar array 1 converted + 1 unfinished (K-415) Further modified K-403 Kazan. Tail now resembles those of the 667BDRM and 949А submarines. The Irtysh-Amphora would later equip the lead boat of the Yasen-class
1991 Yankee Stretch 09774/667АН "Research" Submarine Палтус-class midget submarine 1 converted (K-411) 160 m (520 ft) long. Stated to be an oceanographic vessel, but believed to be a spy sub similar to USS Jimmy Carter
