If there ever was a class that could be justified as being quite invincible in battle...it would have to be what i am going to show you now...make way for the INVINCIBLE CLASS BATTLESHIPS...HMS Invincible and HMS Indestructible. Based on the powerful HMS Agincourt (ex Rio de Janiero) these ships pack fourteen 15" guns in seven 2-gun turrets. The ships' protection scheme is very well-designed, with thick belt armor, conning tower, the whole kit. I wonder what would have happened if these ships opened fire all their main guns at the Germans at the Battle of Jutland. A combined 28-gun salvo weighing 53,760 pounds...just imagine if all those shells hit their target....KA-BOOM!!!!

What do you guys think of the design...is it practical battleship...as far as armament and armor is conerned i seem to be going overboard but is done for protection's sake. I don't want a ship named Invincible to blow up (i.e. like the one at Jutland)

This is the strongest armament i could come up with, because i tried the same number of 16" guns and came up with SS telling me the recoil effect is 1.46, which is really undesirable. So i scaled down the guns to 15-inchers and made a more practical ship out of that.

Feel free to comment more on my design... as well as giving me a realistic timeline (ie could these ships really have been completed in time for Jutland...or am i way off timewise). I want to see what you guys think of these ships...concerning armament, armor, and speed (25 knots can't be called fast...but HMS Agincourt could only make 22 knots...so a shade faster...) For a battleship the seaworthiness and stability is excellent compared to many domestic and foreign designs)

I don't know if any you guys can do this...but i would want someone to estimate the IZ (immune zone) for these ships. At what ranges are my battleships most vulnerable?

Any other comments would be appreciated...I love this design and doesn't seem to ponderous considering the 15" guns reliability and hard-hitting potential.

The size of the vessel - 1,000 feet in length - would very likely dwarf any building slip or dock in the British Isles. No British battleship of Great War vintage was so massive. The first task in constructing such a vessel would be to build the dock in which to build her.

Secondly, under Wesworld rules - which I agree diverge from reality at points - the vessel would require a minimum of 74 months to construct and another 6 to work up, or 80 months. That is nearly 7 years. If laid down in 1914, they might have been ready to by 1921.

Here is my 2nd iteration of my INVINCIBLE Class Battleships. I made them a bit bigger than the historical HMS Agincourt (1913) but carry the same battery of fourteen 12" guns. Protection-wise i was able to squeeze in thicker armor and 2 knots more speed into a ship that devotes much weight to armament. I also fixed a small armament problem i found - 40mm Bofors were not WW1 weapons - so i looked up HMS Agincourt and designed my INVINCIBLE CLASS accordingly, with 6"/45 secondaries and 3"/50 tertiary battery. I also included 4 submerged beam topedo tubes in the design, just to add some sort of ASW capability.

Anyway, comment on these more "practical" battleships, much smaller but still packing awesome firepower.

If these ships were completed in time for action at Jutland (which i presume commencing construction in 1912 would put them at completion somewhere in 1914 or early 1915, perfect for the Battle of Jutland), what sort of damage could they have inflicted on the German battlecruiser/battleships?

I agree with Brock, why would the RN go back to the 12" L45 when they ditched that after the Bellerophon class? If you want a copy of the HMS Agincourt, do note that the RN was the third owner of that ship, so had nothing to do with its original design.

You smug-faced crowds with kindling eye

Who cheer when soldier lads march by,

Sneak home and pray you'll never know

The hell where youth and laughter go.
