No strategic system was ever deployed in a country outside the
United Kingdom, but due to government alliance commitments in the
Middle East and Southeast Asia, the 1957 White Paper's conclusions
on deterrence applied outside Europe as well. In 1960 and 1961,
British tactical nuclear weapons began to be deployed overseas on
Royal Navy aircraft carriers, and at RAF Akrotiri in Cyprus.
In 1962, Prime Minister Harold Macmillan
personally authorized the storage of nuclear weapons at RAF Tengah
in Singapore. Facilities were introduced for handling
nuclear weapons in transit in a number of other countries
Nevertheless, on August 17, 1962, Prime Minister
Macmillan authorized the RAF to deploy both live and dummy weapons
to Tengah. The live weapons were to be held at all times in their
special storage area, but in November 1963 permission was granted
to train with dummy weapons in the open.
Militarily, the justification for these deployments was still the
possibility of limited war between the SEATO powers and China.
Politically, by making a nuclear contribution to SEATO, Macmillan
was trying to gain a measure of influence over U.S. nuclear policy
in a region where Britain and the United States had historically
been at odds; he was concerned, like a number of post-war British
prime ministers, by the risk of U.S. belligerence in Korea, Taiwan,
or Indochina. Macmillan's ministers had convinced him that British
deployments, by contrast, carried no risk. But Malaysian Prime Minister Tunku Abdul Rahman,
although generally pro-British, was not informed. (Singapore had
recently won independence from Britain as part of the Federation of
Malaysia.) The British government had made a visible military
commitment to SEATO, choosing to do so through the relatively
inexpensive medium of a squadron of nuclear- capable aircraft, but
it was coy about admitting, even privately, to the actual presence
of nuclear weapons.
