The US can withhold targeting data prior to launch, or switch off guidance after launch.
That is all stated as fact in the Parliamentary report. Not sure which part you disagree with.
Sure, you might be able to sneak a launch and hope they don't detect it, but that's a little farcical for a £100bn defence programme I would've thought.
- arethuza 11y agoThat's appears to be evidence given to a select committee - so it's one person's view. AFAIK subs don't use GPS underwater - and missile subs spend most of their missions underwater. The missiles themselves use inertial (hence the dependency of knowing the launch point) and star-sighting: "GPS has been used on some test flights but is assumed not to be available for a real mission." https://en.wikipedia.org/wiki/Trident_%28missile%29 https://en.wikipedia.org/wiki/Trident_%28missile%29 I'd be very surprised if the sub don't go to see with at least some target data - kinds of defeats the purpose of the entire system which is set up to give UK Trident sub commanders a surprising amount of leeway: https://en.wikipedia.org/wiki/Letters_of_last_resort https://en.wikipedia.org/wiki/Letters_of_last_resort [Edit: For the record - I am rather passionately anti-Trident and would strongly prefer the UK didn't have them].
