HC Deb 19 December 1979 vol 976 cc279-80W
Miss Richardson

asked the Secretary of State for Defence what is the shortest anticipated time between detection of nuclear missile attack from the Soviet Union and the arrival of these missiles upon likely targets in the United Kingdom.

Mr. Pym

The time between detection of a nuclear missile attack and the arrival of these missiles upon likely targets in the United Kingdom would vary depending on the place of launch, the trajectory of the missiles, and whether the attack was part of an offensive against both the United States and United Kingdom, or against the United Kingdom alone.
