Trident Missile Test

Lord Hennessy of Nympsfield Excerpts

Monday 23rd January 2017 Lords Chamber

[Earl Howe]

My Lords, I can only repeat that we have absolute confidence in the operation of our independent nuclear deterrent capability and that the effectiveness of the Trident nuclear system—should we ever need to employ it—is absolutely assured. I would add only that I often reflect on the importance of not believing everything one reads in the press. This is a classic example of the application of that principle.

[Lord Hennessy of Nympsfield (CB)]

My Lords, I declare an interest in that I witnessed the launch in question from the survey vessel two and half miles away from where the missile came out of the sea. I put it to the Minister, with great respect, that it would make it much easier for those of us who very powerfully support the independent deterrent, and the building of the four “Dreadnought” submarines in the successor class, to make the case generally in the country when we are interviewed in the media if the Minister could assure us that a full analysis has been successfully made of whatever went wrong—I have no knowledge at all of the nature of what went wrong—and that remedies have been put in place. I understand that every particle of a D5 missile is riddled with the highest security classifications, but in this case, such an assurance could be possible and would be very welcome.

[Earl Howe]

My Lords, the most important assurance is the one that I have already given: this is a system in which we have absolute confidence. It has never been the practice of government to give Parliament details of submarine operations or of the systems and subsystems that are tested during a demonstration and shakedown operation. But I hope I have said enough to reassure noble Lords about our deterrent and its reliability.
