There's no visiting the flight deck.
Having been on my “tour” today, I can confirm that is exactly it. Slightly disappointing but still very enjoyable nonetheless and I’m grateful for the opportunity.

Ha! This is great - must admit this is the one area we avoided as it was very loud (and very overrun by kids!)

According to this Merlin in the Autumn and F-35 in January 2021 off the East Coast of the US.

It also mentions that someone said PoW was 4 metres longer......and 3 knots faster than QE. I think they're taking the mickey now....mind you it does confirm a top speed of at least 32 knots as QE was on AIS at over 29 knots in trials...

The claims for the differences between the two are now getting pretty weird.

I’m a total layman. However it seems generally well accepted that for any given hullform you need an exponential increase in power for every extra knot of speed.
So (layman, remember) to increase speed by 3 knots you’d need 30-40-50% more power or a radically different hull.

That’s clearly BS. So the only thing I can think of that would explain this is full power trials carried out in totally different conditions.

And I find that difficult to buy also.

Weird.

Hi- doesn't a longer hull confer greater speed without an increase in power? Just remembering transom hulls and stern flaps to trick the ship into thinking its got a longer hull...

In general yes, but a 3-4 metre extension isn't going to get an additional 3 knots. Most of the measures like transom hulls or stern flaps tend to get 0.5/1 knot increases or a higher efficient cruise speed.

(Forces TV) 2nd March 2020
More than 10,000 members of the public have been allowed on board Britain’s newest Queen Elizabeth-class aircraft carrier for the first time. HMS Prince of Wales arrived in Liverpool on Friday for a week-long visit.

From 44 secs in for about 4 secs I can just see my Lad's upper body all on his own by his GPMG! Daniel Johnson, made in Pompey, soaked in the RN :lol:

From what I vaguely remember, PoW spent less time in Rosyth basin than than QE. Not only was her total build time shorter, but she spent more of it in the dry dock before floating out into the basin. (I'm sure somebody can check this.)

So it is possible that PoW had a much cleaner bottom during her sea trials, compared to QE. That could account for some of the difference.

Favourable winds and sea currents could account for some of the rest. Especially for a crew eager to exploit them in order to beat a clear target set by their sister ship.

Queen Elizabeth was floated-out on 17 July 2014. On 26 June 2017, she left Rosyth for the first time to commence sea trials.

2 yrs, 11 months, 9 days in Rosyth basin

Prince of Wales was floated-out on 21 Dec 2017. On 20 Sept 2019, she left Rosyth for the first time to commence sea trials

1 year 8 months, 30 days in Rosyth basin.

So QE spent about 35.5 months floating in Rosyth basin, growing stuff on her hull, before leaving for sea trials.
PoW spent about 21 months floating in Rosyth basin before leaving for sea trials.

A little bit of reading suggests that fouling may reduce a ships speed by up to five percent ,copper based anti fouling paint which is the more common practice to deter micro organisms are not as effective as the previous paints which were heavy polutatnts ,but government defence research bodies do a lot of work on paints for naval vessels that have benefits for the capabilities of ships not as obvious as guns but just as classified theres more to the paint on a ship than its colour perhaps someone on this forum can go into the details and capabilities of R.N paint lol

Modern RN paints have pretty much eliminated this.

PWLS off soon, if the weather up there is like it is in Pompey at the moment it'll be a lot nicer than when she arrived. My nipper said that an F35B may make an appearance and do a flyby around 1600, but obviously this is subject to weather etcetc

Interesting, even the Yanks are considering 'downsizing' their Nuclear Carrier ambitions..

https://www.thedrive.com/the-war-zone/3 ... ers-report

Now at then end of the day I don't think they'll be able to bring themselves to take the leap and go for a CATOBAR QE class type carrier in the 70,000t range, vested interests & sheer national pride will stop them from doing so.

..But the fact they are even considering it, shows that their plan for a fleet of 10 Ford class CVN's is stretching even their finances to breaking point.
