Multilateral Force

The Multilateral Force (MLF) was an American proposal to produce a fleet of submarines and warships, each manned by international NATO crews, and armed with multiple nuclear-armed Polaris ballistic missiles. The proposal was floated by the Eisenhower and Kennedy administrations.

The proposal was inspired by the complaints of NATO countries that the nuclear defense of Europe was beholden to the Americans, who held the bulk of nuclear capability. The result would be a fleet of warships manned and operated by NATO command, instead of an assortment of independent forces ultimately under their own domestic banners. In this way, other NATO powers were theoretically ensured an active role in European defense.

The idea of using surface ships as part of the force received criticism in Europe, who felt that surface ships would be vulnerable to attack, while a wholly submarine force would be more difficult to eliminate. President Kennedy argued that using only submarines would defeat the purpose of minimizing American control of the force, as the United States was the primary power capable of building the requisite number of submarines and training their crews. Including surface vessels would allow for greater European involvement in both construction and training, argued Kennedy, who also dismissed the notion that an entire pan-Europe nuclear-armed fleet could be eliminated before any of them could commit retaliatory strikes.

The proposal eventually fell flat when American and European differences over basing strategies and financing could not be reconciled. The Italian cruiser Giuseppe Garibaldi was actually refitted with four launchers for Polaris missiles. Despite the successful launching tests, the U.S. never went ahead with the MLF. Instead the Italian Government set to develop an indigenous missile, called Alfa, with a successful program, officially halted by Italian Nuclear Non-Proliferation Treaty ratification.

The prospect of having Germany in the Multilateral Force was mocked by Tom Lehrer in the satirical song "MLF Lullaby".

MLF experiment on USS Claude V. Ricketts
From June 1964 to the end of 1965 USS Claude V. Ricketts (DDG-5) was part of a mixed-manning experiment for the proposed MLF. Its crew consisted of 10 officers and 164 crew from the US Navy with the remainder filled by sailors from West Germany, Italy, Greece, the United Kingdom, the Netherlands, and Turkey. Though the MLF never was created, Secretary of the Navy Paul Nitze stated that the project on Claude V. Ricketts was successful.
