I have repeatedly said at this Box that so long as the threat is predominantly from manned aircraft, where the warning time is considerable, the Thor weapon is a perfectly effective second-strike weapon. When the threat comes from missiles, where the warning time is much shorter, then, of course, its value will diminish. Therefore, while I have said that at some point we will phase out the Thor missile, we are not yet in a position to say what the right timing will be. At the moment, it constitutes a valid deterrent in the second-strike rôle.
