HMS Queen Elizabeth

Don't forget that when they float her out of the dock she'll be lacking a lot of equipment etc. so will be light and therefore floating high
Not to mention fuel and other liquid stores so she will be sitting very high in the water while they float her out. Google has pictures of last year's USS Gerald R Ford float out - the before and after pics show she was barely using half her expected operational draught.Kenty said:
Wasn't there something on the news recently that the channel has to be dredged for her to leave, at a cost of around £40M?
It was only in the news because some MP asked a question in Parliament, got a perfectly reasonable answer and then proceeded to spout off nonsensically anyway.It was always part of the project that Portsmouth will be upgraded to support the new carriers. The harbour channel will be deepened and new jetties built (the existing ones are past their sell by date anyway). Various other upgrades to HMNB Portsmouth will involve a new dedicated power supply (either generated on site or a new connection to the Grid) to supply warships alongside. Not surprisingly some silly councillor got his name in the paper by claiming they would take power from the city supply and cause power cuts.

That last picture really make it looks like the boat won't actually float when the dock is flooded
Has anyone checked because otherwise that's going to be a touch embarrassing!
Of course it will float and get out the dock, this is an example of great modern Brunelian precision engineering........er............ok, bad example - http://en.wikipedia.org/wiki/SS_Great_Eastern#Laun...Has anyone checked because otherwise that's going to be a touch embarrassing!

I didn't post that message last night, that's really freaky

What's a brake propeller ?
I'd guess it's something that allows the shafts to be driven under power without generating any propulsion - but that's purely a guess.
Pretty much. They produce a much more violent wash/wake than a regular prop because they don't produce any thrust. They're used to check mounting systems for equipment, and vibration/fatigue allowances.I'd guess it's something that allows the shafts to be driven under power without generating any propulsion - but that's purely a guess.
The comment about it not having the props fitted wasn't so much to point out that they'll be using brake wheels, it was more that it'll likely be leaving the dock with no prop/wheel fitted, as they might need the extra little bit of clearance it provides.

How do they fit props if not while the thing's in drydock? Fitting them while afloat seems rather impractical.
With great difficulty.hidetheelephants said:
SRSLY? Jings, who thought that would be a good idea? It's hard enough wrangling a 50 tonne lump of bronze that cost £1m+ when you're stood on concrete and can use cranes. Who signed off on it, so I can go round their house and throw eggs?
Probably the same person that signed off on Rosyth as the build yard in the first place.And the MP who's constituency, Dunfermline East, borders Rosyth obviously had no influence on that decision

Long studies were done on where the ships could be assembled and given the size and draft of the ships Rosyth was the only option within GB without developing new facilities or recommisionimg some of the old North Sea oil rig yards. And the MP who's constituency, Dunfermline East, borders Rosyth obviously had no influence on that decision

And even then they are too big to get in to Portsmouth at all states of the tide. There will probably periods when they have to anchor at Spithead and not come in to Portsmouth.andy97 said:
