Strategic Defence and Security Review

On the risk that has been created around renewal, the alternatives to Trident review, to which my right hon. Friend the Member for Newcastle upon Tyne East referred, will be led by the Minister for the Armed Forces—it is a shame he cannot be here for the debate. Essentially, the review uses Government resources actively to explore the idea of adapting Astute class submarines for nuclear capability that falls far short of being a deterrent. That could be a cause of increased proliferation and could increase the risk of confusion. If a cruise missile is launched from a submarine at a point of war and the aggressor nation does not know whether it is nuclear or conventionally tipped, the prospects of escalation and horrible consequences increase. The Government have put that in train and we await the review. In conclusion, the delay in the proposed in-service date of the successor to the deterrent is—it must be stressed—driven not by national security or primarily industrial concerns, but by a political fudge to delay the vote until the next Parliament. That creates increased costs for taxpayers because the overall cost of renewing our deterrent will increase. In addition, it risks stretching the life of the current Vanguard class submarine to the limit of safe operation. Pressure on the delivery timetable of the successor has been increased by putting political deals above the national interest.
