§ Mr. BennettTo ask the Secretary of State for Defence, how many computer modelled tests have been carried out under the Anglo-American mutual defence agreement, to nuclear weapons or major parts of such weapons by the United States of America for the United Kingdom and vice versa.
§ Mr. FreemanComputer modelling is a tool used extensively as part of the design, development and qualification of United Kingdom nuclear weapons. Under the auspices of the US-UK 1958 mutual defence agreement, there is an on-going exchange on techniques and data associated with computer modelling. The Ministry of Defence does not hold a database of every individual computer simulation which has been conducted or discussed with the United States and such information could be provided only at disproportionate cost.
