§ Lord Kennet
asked Her Majesty's Government:
Whether it is their view that the development of any materials or systems under the strategic defence initiative is precluded by the ABM Treaty (Official Report, Commons, 14/11/85, col. 259).
§ Lord Trefgarne
The ABM Treaty places severe limits on the development of ABM systems, including a prohibition on the development of ABM systems which are sea-based, air-based, space-based or mobile land-based. The treaty does not place any specific limits on the development of materials. The strategic defence initiative is a research programme, which the US has stated will be conducted within existing US treaty constraints.
