Was 18"/40 ever considered for Admiral class?
While it seems counterintuitive to put a small number of slower firing guns on a fast battlecruiser, was the 18"/40 from HMS Furious considered for the Admiral class? Perhaps if Admiral Fisher had...

If the four 4x18" Admirals had been built before the Washington Treaty, what happens to them by WW2? With a ROF of 1 per minute, these ships will have little use at Denmark Straight, etc. Perhaps...

Don't know for sure about the Admirals, but from what I've read of their design history (mainly from the HMS Hood Association website) there was never any consideration of anything other than 8 x...

Those look like mean shore bombardment guns. I wonder how they would be as harbor defense guns?

. In the NMM's Brass Foundry's drawing collection is a diagram showing the firing cycle for an 18-inch gun dated 1922 (BUT it doesn't indicate the Mark of gun) - the firing cycle is 30 seconds.

In time when Admirals were still battlecruisers with 8" armour belt, there was consideration of ships armed with 4,6 and 8 x 18" guns. I could not find which model, but C40 was only available that...

In the right place they'd be pretty good coast defence, range of about 40,000yds. Britain showed little interest in CD but had they been about at the time they might have gone to Singapore in lieu of...

Larger HE shell means larger bursting charge. In those shells you don't care about penetration of armour so don't care about muzzle velocity unless required range is reached and shell is stable in...

Yes, but HE is much less dense than steel. 80cm Dora concrete piercing shell 7,100kg, HE 4,800kg. Not sure but a very heavy shell with low velocity might lead to dangerous barrel pressures.

So shell will very long. Not only high pressure to gun but also needed differed spin. Forex from standard gun could be unstable

Which is why I don't understand these "4,000lb" HE shells; I suspect the existing ones sacrifice HE effect to keep the same ballistics as the others, an optimised HE would probably be lighter.

I suppose what I have in mind is a more robust, four gun version of Furious.

From a practical point of view the Admiralty felt that you needed a minimum of 6 guns to make an effective salvo, but 8 would be better. This strategy would probably have been applied to the Admiral...

You could try and build a design for 9 x 18" guns with more than a few dozen shells for each barrel. Only disadvantage is that it might come to about 63,000 tons! You would also probably have to build...

But there was 8x18" "design". Actually with original 8" armour belt not much bigger than final Hood with 15" guns and 12" belt.

The 18" turret used sighting ports in the face rather than the roof, as did the 15" MkII used in Hood. Could be firing over other turrets was a concern or could be that this was now the preferred...

I thing that sighting hood problem is overblown. In battleships there was no problem at all. They were intended to fire more or less broadsides, so who cares? Superfiring was wAy to shorten citadel...
