Anne-Marie Trevelyan asked the Secretary of State for Defence, “how long it would take, and at what cost, for her Department to procure a Trident D-5 missile.”
Stuart Andrew, Parliamentary Under-Secretary of State for Defence, responded “The UK’s Trident II D5 missiles form part of a pool of available missiles shared with the US. The UK pays an annual contribution to the continued maintenance of the missile stock based on our share of the overall missile inventory.”
