KNS Orient: One-off experimental battlecruiser
The Orient is a one-off battlecruiser built for the Khertland Navy designed to fill in the gap INN Ostland left behind. The ship was modestly armed compared to other navy ships with only nine 12" guns. The dual-purpose secondaries were similarly modest and no smaller AA guns were mounted.
The vessel was a test bed for a new sloped armor scheme, which purportedly increased effectiveness by at least two to three times.

In early December of 2015, Fleet Admiral Derfla nov Retep created the INN. He envisioned a large fleet of powerful battleships. A key feature that will help distinguish it from contemporary warships was the use of a sloped belt. A number of experiments with sloped armor ranging from the 'Ocean turtle' to the massive battlecruiser Ostland. Initially, they seemed successful due to flawed testing.
Eventually the navy found out sloped blocks were falsely advertised. Ostland also had many flaws outside of inadequate armor protection, such as poorly designed anti-air and secondary armaments.

The vessel was somewhat succeeded by the Varsenda which had similar requirements however was a heavy cruiser instead and also used vertical armor plating. Varsenda was obsolete by the time it entered service and changes to the original specification sparked a discussion for a replacement.
Eventually the navy presented the Ikaros class. Featured improved protection and equipped with very heavy firepower. though once again largely dated by the time it entered service.

At this time, Derfla nov Retep once again suggested the idea of sloped armor. This time with the use of spinblocks. A number of potential drawbacks and difficult construction resulted in other high ranking officials to hold the idea in very low regards. Derfla eventually convinced them to test it out. Ikaros class was split in to two design. One with conventional vertical armor and another with sloped design.
The 2nd ship was built but as a upgrade of the first and utilized CRAMs during the CRAM fad.
So the sloped armor was pushed for a unplanned 3rd ship, making it the largest class of warship at the time. Construction never began.

Fast forward to February of 2017. The Orient was ordered, in essence it was a successor to the Ostland battlecruiser, bringing back the sloped armor concept.
Though the design is derived more from the Ikaros class.
Using the spinblock sloped armor idea originated back from that time, it also utilized a similar turret protection system with the explosive clip at the lowest part. Rather than gauge increasers forming a wall, metal armor was provided. The gun barrels are also buried like the Ikaros. Though it was fully enclosed so it had lower elevation due to the armored roof. One of the partial secret to the ship's accuracy.

The ship's 45 degrees sloped belt not only made shells forced to go through 5m worth of metal beams, instead of the real 3m thickness... It also increased likelihood of a ricochet and perhaps more importantly, due to the impact angle, the armor stacking is calculated along the height of the armor rather than thickness.
A angle any less than 45 degrees would create gaps where a shell has a potential of penetrating an area where only the 'side' of the blocks. At a 45 degree angle, at least 2 beams along the penetrated path would encounter the 'top' and hence impact against armor value that is equal to the height of the impact.

This make it an extremely effective armor scheme against AP rounds.
But the spinblock was a particular vulnerability, notably to high explosives.
In order to house the armor, the ship became really wide, but it also had the added benefit of giving the decapping plate a significant distance from the spinblock which is furtehr protected by the belt.
This decreased the dangers of torpedo attacks and explosive projectile to a bare minimum. The decapping plate was considered sufficient against HE rounds, though torpedo protection was the primary concern. In the end, the thick belt armor proved useful in acting as a torpedo belt too.

The ship belt is 3m thick and runs around 50% of the ship's length. It starts a little ahead of the turret #1 and ends slightly aft of turret #3.
The lower section of the belt is actually thicker at 4m to help protect the spinblock from torpedo attacks and tapers to 3m as it gets closer to the deck.
The belt armor is separated in to 16 sections. 8 on each side, primarily to prevent a single spinblock hit from detaching the entire armor.
Because the deck armor needed to move up and protect the superfiring turret, there would of been a gap in the belt armor, unless it had less sloping. This meant the ship had to be made wider starting from the superfiring turret to make room for a taller belt amidship. It also made the hull taller, the transition was give a gradual sloping resembling somewhat like the yamato.

To further prevent explosive damage and flooding, a armored bulkhead of 1m thick is located behind the belt armor. The 2 magazine areas is as thick as 3m. Though transverse bulkheads were armored 1m around the magazine. The magazine is spaced to prevent a catastrophic chain reaction. The lower deck for the magazine is also 1m thick in addition to the main deck armor.
Engine space is contained in a 1m thick metal cofferdamn to also provide further protection.
Turrets barbette is partially mixed in to the longitudinal bulkhead, hence can be one an the same. The barbette is 2m thick on the top against plunging fire. everything else is 1m with a 3m armor block around the LWC and turret block since torpedo hits occasionally knock out turrets.
The main deck is 1m of metal under the wood decking.
The citadel area is closed off on both sides by a 1m thick armor plating.

Turrets are protected by 2m of face armor. The side and rear is by 1m and is starting to prove inadequate. The stalk is protected by a layer of metal on top to stop plunging fire. The front is also protected by 1m of armor to stop penetrations in to the explosive clips. so far proved somewhat effective.
The turrets are separated from other vital components to prevent catastrophic damage. The conning tower is protected by 2m of metal all around except fort he side which is 4m, making it one of the most protected areas anywhere.
Despite original intentions, the ship is not double bottomed. But the citadel portion of the hull bottom is armored.

With all this, the ship became very wide and long relative to the gun size. Lots of empty deck spacing. The bow and stern largely became unarmored empty areas for fuel.
The vessel was largely kept simplistic due to its experimental nature. Armament was fairly modest which reflects it's experimental nature hence lack of investment on heavier firepower. The ship can attain 29 knots, fast but not fast enough considering it is a battlecruiser.

The ship have two spotting towers. It have two fire control radar sets and three optical fire control directors. This gave the ship accurate firing solutions. The 12" guns on board the warship is designed to take out smaller warships, hence the use of a high velocity HE round with fairly high accuracy. The dispersion is nice even at a max range of 4.5km.
While design features resembles that of Ikaros, and a spirit that derives from teh Ostland, the role is different from the two. Rather than fighting against equal opponents, it was meant to fight ones smaller than it. Smaller ships, that have much less potent HE rounds, and lack adequate AP rounds to go through such armor. The rather quick firing accurate 12" HE gun make it an effective cruiser killer ship.
This also became the first ship to use wires in the navy. It is heavily influenced by the Yamato and US standard battleships, both of which were unintentional until it became necessary.
The ship enter service as part of the surface combatant fleet.

RE: KNS Orient: One-off experimental battlecruiser
I really like that cross section you provided - the hull shape is really interesting. So much so that I may have to borrow bits and pieces of it for my next battlecruiser...
