HC Deb 11 March 1971 vol 813 c146W
Mr. Skinner

asked the Minister of State for Defence what information has been obtained under Article IV of the Nassau Agreement; and what effect it has had on the development of the British Polaris Fleet.

Lord Balniel

There has been a continuous flow of information between the United States and United Kingdom Governments on modifications to the Polaris Weapon System under the terms of Article IV of the Polaris Sales Agreement of 1963. The United Kingdom has accepted and incorporated the large majority of these changes with consequential improvement in the reliability of the Polaris weapon system in our Polaris submarines.
