The Holy Loch Polaris Base: American Submarines on the Clyde, 1961–1992

Each major claim carries one of three labels. established means supported by primary records, official bodies or several independent reliable sources. shared means the core fact is sound but sources disagree on details, dates or interpretation. traditional means widely repeated but not traceable to a primary or independent source.

Protest numbers vary widely between police, press and campaign estimates, and are given here as ranges where sources differ. Details of operations and incidents at the base remain partly classified.

Why the Holy Loch?

established In 1960 the United States was deploying its first submarines armed with Polaris ballistic missiles and needed a forward base close to Soviet waters. Britain, which hoped to buy Polaris for itself, agreed in November 1960 to host a US submarine depot ship in the Holy Loch, a deep, sheltered inlet off the Firth of Clyde near Dunoon. The base would be a floating one: a large tender, or depot ship, moored in the loch, with submarines tied alongside for maintenance and resupply between patrols.

The arrival

established The tender USS Proteus was due in December 1960 but was delayed. The authorities brought its arrival forward to Friday, 3 March 1961, partly to limit the number of demonstrators. When it sailed in, protesters had only three canoes and a dinghy to block it, and some who tried to climb its anchor chains were pulled off by American sailors.

The protests

established The Holy Loch base gave birth to the anti-nuclear movement in Scotland. A rally in Glasgow in December 1960 drew about 2,700 people, and a march in February 1961 between 4,000 and 10,000. In May 1961 the Direct Action Committee Against Nuclear War organised a combined sea and land action: about 70 protesters tried to board Proteus and were driven off with water hoses, and 32 were arrested at a sit-in at Ardnadam pier. In September the Committee of 100 held a sit-in at Ardnadam at the same time as its mass protest in Trafalgar Square; 351 people were arrested at the Holy Loch.

shared The campaign did not remove the base. But it shaped a long tradition of Scottish anti-nuclear protest, later focused on Faslane, and produced songs such as "Ding Dong Dollar" ("O ye canny spend a dollar when ye're deid"), which mocked the economic argument for the base and are still sung.

Life with the Americans

shared For thirty years Dunoon and the Cowal peninsula lived alongside thousands of American sailors and their families. The base brought money, jobs, American cars, baseball and marriages between local women and US servicemen. Many locals remember the Americans fondly, and the town felt the economic loss when they left.

Departure and legacy

established With the end of the Cold War, the US Navy withdrew. The last US missile submarine left in November 1991, and the site was handed back to the Ministry of Defence in June 1992.

established During the American years a large amount of waste, some of it toxic, was dumped in the loch and left on the seabed. Clean-up of debris and contaminated material became an issue after the base closed.

Holy Loch and Faslane

established The Holy Loch base is often confused with Faslane, on the nearby Gare Loch, which has been the home of Britain's own nuclear-armed submarines, first Polaris from 1968 and later Trident, and which remains in service. The two were distinct: Holy Loch was American; Faslane is British.

• The US Navy's Holy Loch base was a floating one, centred on a depot ship moored in the loch.
• The first protest blockade in 1961 consisted of three canoes and a dinghy.
• 351 people were arrested at a single sit-in in September 1961.
• The protest song "Ding Dong Dollar" was written against the base.
• The last American missile submarine left in November 1991.

• Myth: The Holy Loch base and Faslane are the same. Holy Loch was an American base from 1961 to 1992. Faslane, on the Gare Loch, has been home to Britain's own nuclear submarines since 1968 and remains in service.
• Disputed: How many people joined the protests. Numbers vary widely between police, press and campaign estimates, so crowds are given as ranges, such as 4,000 to 10,000 for the February 1961 march.
• Myth: The base closed in 1992. The last US missile submarine left in November 1991, and the site was handed back to the Ministry of Defence in June 1992.
• Disputed: What the base meant for Dunoon. Many locals remember the Americans fondly and the town felt the economic loss when they left. Protesters saw the base as making the Clyde a target in a nuclear war.
