Overview
The Rāshidūn class came from time spent researching what the RN called mid sized capital vessels, and also came when the North Borneo class was being laid down. Lessons learnt from ship design for the RN itself were applied and the new armour scheme - the Collingwood Pattern, was applied to both the North Borneo and the Rāshidūn, giving the Rāshidūn a top class armour scheme. In addition, both constructions used similar guns and similar gun styles, though admittedly the Rāshidūn had heavier armour, more missiles, and was slower, due to the needs of the KLM Navy. The Rāshidūn however, was thought to be a sister class of the North Borneo, as it was laid down in the same yards and often visually thought to be the same.
Construction
The Rāshidūn's most obvious construction feature are its two funnels and two main superstructures blocks - one for the bridge, ahead of the funnels, and one behind the funnels, with the main RADAR array. The main RADAR array was extremely powerful and as such needed a large space to accomodate it. Behind the main RADAR array the secondary VLS array of 800 missiles sits, with the first VLS array being in front of the main guns and the third ahead of the main guns. The main guns themselves sit on heavy barbettes which required 11,000 extra tons of keel reinforcements to support the magazines, with three barbettes for'ard and two stern. She has a bulbous bow, reducing wave resistance by 14.1%, and a transom stern.
The Rāshidūn class displacees 1,110,000 tons of water at full displacement, making it a full blown SD in the minds of many. 894 metres long, 120 metres wide, and with a draught of 21 metres, the Rāshidūn is also a rather large vessel. Her block coefficent is .650, giving her a very warship like look - much like the Iowa class, which also reduces her wave resistance by 6%.
Protection
Of the 900,000 tons empty displacement, 50% of that is armour - 450,000 tons. This large percentage (Iowa and Bismarck being 45%) came from the KLM call for a heavily armoured battleship.
The belt armour stretches an amazing 80% of the length. It's first layer is 660mm of HSLA steel, its second being 400mm of titanium, and the third a honeycomb support network made entirely from tungsten rods. This makes the battleship extremely expensive, but also extremely resistant. Thanks to the well forged and well placed metals and the angling and construction, tests confirmed that the battleship could, at certain points, entirely defeat the 635mm/25" naval shell, used extremely widely by NS navies. This makes the Rāshidūn class EXTREMELY durable.
The deck armour of the vessel is constructed from the same kind of layering system, with 500mm of steel and 300mm of titanium, with a 150mm tungsten decapper over the top layered with teak (the strongest kind of wood - in fact, they can't even get inside the Bismarck's armour after sixty years because they can't get through the teak) to stop any splintering sheets of metal. Behind that the typical tungsten honeycomb supports the deck.
Extensive pumping and flooding runs through the ship, with hardpoints for completley flooding rooms to stabilise and remove lists of up to 30 degrees.
If buttoned down, the bio and chem weapons will be completely useless against the ship. There are enough MOPP suits to protect all the officers of the vessel.
Weaponry
The Rāshidūn carries both an impressive gun and missile armament. The guns are set out in 5 quad turrets, for a total of 20 barrels. The guns themselves are the 27.1inch/90 naval mark II RP12 cannon, which can elavate to 52 degrees and fire the newly devleopde supercharged shell which weighs 6.75 tons to a fantastic 166km without ERGMs. Each turret holds 250 crewmen and it takes 54 seconds for each cannon to be reloaded. The turret weighs 12,450 tons, the magazine holds 400 rounds total and weighs 6,000 tons total, and the barbette reinforcement 11,000. That makes the weight for each turret actaully 29,450 tons.
The main missile armament comes from 3 VLS arrays, each with 800 cells, counting to a maximum of 2,400 VLS cells. each cell is a metre wide, a metre deep, and 11 metres in height, allowing it to fit the largest ASHMs.
In addition, 24 quad RAM launchers fire small, agile missiles to intercept close range aircraft and act as point defense alongside the 160 40mm autocannon emplacements and the 13 triple 55mm autocannon CIWS.
Propulsion:
Propulsion is the CONAS system. Four nuclear pressurised water reactors and eight shafts provide the four waterjets with 600,000 SHP of power, driving the vessel at 27 knots max and 17 cruise. Additional steam turbines provide an extra 250,000 SHP allowing the ship to 'sprint' at 29 knots.
