Looking forward to lots of nice ship
Not sure it matters much did the RN have to stop using 4.5" guns in one battle due to them stopping the 15" actually ranging properly ?
(WW2 Renown ?)

Can't say I've ever heard of the Renown having to stop the 4.5" to allow the 15" to fire. I can't think of any reason, it certainly would not have been shell splash, maybe vibration, or cordite smoke. Be interesting if you can find the reference to it JSB.

Ocean Class Armoured Cruisers

These were the last two ships completed under the Naval Acquisition Act. Like all ships of their type, they were longer than the equivalent battleships, but with less armour and tonnage to allow them to be faster. These two ships had a single calibre armament but as the guns were 7.5" they did not scare too many enemies. Like the other ships of the NAA they were turbine engined and had more power for their size of installation than their competitors. They were faster and could maintain their speed better than the reciprocating engined ships. Part of Atlantis' squadron to the North Sea, the two Ocean class were with the fleet at Jutland as part of the 1st Cruiser Squadron and were heavily involved fighting with German light forces. At one stage the Pacific came within range of the vanguard of the German battleships and received major damage from the 12" guns. It took 8 months before it could be proclaimed 'as good as new' again. With a short stint after the war as training ships, both vessels were retired from service in 1924 and scrapped.

A Class Torpedo Boats.

Buried in the minor vessels in the Naval Acquisition Act were twelve Harbour Defence Torpedo Boats. These ships were to be based in groups of 4 at the major harbours, Demeter, Hyperion and Artemis. At 300 tons, 180x18 feet, these were not big ships but they carried a punch to threaten much bigger ships. With 2x75mm and 2x47mm the gun armament was to provide the distraction to allow the ships to get within range of their 4x18" torpedo tubes. These ships were also turbine engined with 6,000shp for 32 knots.



Four of the class were transferred to Gibraltar where they provided anti-U-boat patrols 1915-1918. A5 and A6 provided the highlight when they sank UC25 which was trying to force the straits into the Mediterranean.

Nice work.

Poseidon Class Battleships (or My Countries First Dreadnought)

Displacement: 23,000 tons standard, 27,700 tons full load.
Dimensions: 527 x 86 x 28 feet
Machinery: 2 Shaft, Steam turbines, 34,000shp
Speed: 24.5 knots
Endurance: 6500 miles at 15 knots.
Armour: 12" belt, 2.5" deck, 12" CT, 11" turrets.
Armament:
8 x 12" (4x2)
12 x 5.5" (12x1)
8 x 75mm (8x1)
Crew: 850 (915 as Flagship)

Laid down in 1904 and completed in 1908, these four ships caused quite a stir when they appeared as Atlantis' representatives at the 1911 Coronation review. The Poseidons set the standard for future Atlantean battleship production. The heavy armour and much better steam/power production gave these ships a decided edge over their peers in other navies.



All four ships were in the Mediterranean from 1915 to 1918, based at Taranto and forming part of the Adriatic force to hold the Austro-Hungarian Navy from breaking out. The four ships served till 1925 when they were required to be scrapped under the Washington Treaty on completion of the two Zeus class battleships.

Looks good, a bit underarmed for the displacement, but I guess you chose speed and protection. Just a question: why do you have bulges? I'd expect them in a reconstruction, not in a new ship.

because, when I drew that ship back then (long ago). I drew it with an bulge

I have been trying to think of reasons why the ships may have been completed with a bulge - from the shape of the bulge it is quite hydrodynamically smooth and would have quite good flow properties across it. How the bulge would affect the running of the ship speed wise I have no idea. The RN ships that get bulges, they do not seem to list a different speed for the before and after. The other problem I could see was with the armoured belt. With the Poseidon I would say the belt would have to be internally mounted, because there is no belt showing outside of the bulge, which I would expect for the belt to cover from A-Y magazines.

I will add another drawing to that post with the bulge removed and with an external belt and see how it looks.


Version 2 with armoured belt, bulges removed:

Lion Class Destroyers.

First ocean going destroyers built by Atlantis, the Lion class were the result of close examination (who said 'spying') of the destroyers being built by other navies. The armament was three of the standard 75mm guns with two 47mm cannons. These ships showed that the 75mm gun needed to be replaced with a larger calibre gun for anti-torpedo boat work. The main advance for these ships was the introduction of the 21" torpedo, replacing the 18". This was part of the 'Vermuyden' revolution where he had designed new motive power plant that allowed for larger torpedoes carrying larger warheads.

The four ships were refitted in 1913 with 3x90mm replacing the 75mm. Convoy escort duties were there lot during WW1. From Atlantis to Gibraltar and Gibraltar to Britain.

All four ships were discarded and scrapped at wars end.

Lovely work Krakatoa
