§ Lord Kennet
asked Her Majesty's Government:
Whether they consider that the work described in a recent United States Department of Energy document on upgrading and replacing the B-61 gravity bomb, the W-87 warhead for air-launched missiles and the W-76 and W-88 warhead for submarine-launched Trident missiles may amount to a breach of the provisions of the comprehensive test ban treaty and of Article VI of the non-proliferation treaty, for both of which the United Kingdom is a depository power.
§ Baroness Symons of Vernham Dean
The depository of the comprehensive test ban treaty is the United Nations Secretary-General. We have no reason to believe that any developments proposed by the United States are in any way in breach of their obligations under the non-proliferation treaty or the comprehensive test ban treaty.
