§ Mr. Cohenasked the Secretary of State for Defence if he will specify the number of nuclear weapons (a)possessed and (b) operated under dual key arrangements by the United Kingdom in each of the following ranges: (i) 0 to 500 km, (ii) 500 to 1,000 km, (iii) 1,000 to 5,500 km and (iv) 5,500 km and above; and if he will further subdivide each category into land, sea and air-based systems.
§ Mr. Ian StewartDetails on the number of United Kingdom nuclear warheads is classified, as is the number of United States nuclear weapons assigned to United Kingdom nuclear delivery systems. However, unclassified information about United Kingdom nuclear forces is summarised in paragraph 404 of volume I of the "Statement on the Defence Estimates 1986" (Cmnd 9763). I also refer the hon. Member to annex A, volume 1, of the "Statement on the Defence Estimates 1987" (Cmnd 101-I), in particular figures 15 and 16, which show NATO's nuclear systems according to range.
