Ship

Low Vis SHBC

Wow its as fast as a torpedo cruiser or a high speed escort cruiser, wow. You can only see it from the horizon rather than from space, wow.

Fast Raid Battlecruiser.

Sequel To: https://hoidesigner.com/design/2ede1f18-4869-469d-9c95-6e8e87f0fcd5 A battlecruiser that uses the fact that 113mm dp secondaries have a typo in their speed stat alongside two useful doctrines "The new scool" and "fast battleships" to achieve a faster ship then my fast raid HC with much higher overall attack, and armor. With a good admiral, chief of staff, and raiding shipbuilder, you can get the visibility down to 11-13 and the speed close to 55, making the hit chance of enemy guns very low. Between the naval spirit "Surface Raiders", we have 50% screen without screens, giving enemy torpedoes a hit chance that is worse than the worst possible hitchance on its own, much of the enemy torps are lost to screens that don't exist. Lovely. The only flaw is you need fleet carriers somewhere to level this bonus, build them early on and exercise them to level 2 if possible. 50% screening efficiency also gives about 10% retreat speed and 20% gun accuracy. 60% is not possible here as our speed requires us to give up armored raiders, but I figure this is a worthy sacrifice for the delicious speed cheese. Our air attack is, regrettably, a bit worse then the previous ship, so the damage reduction against bombers will be a fair degree lower (~55% solo instead of ~65%,) but air attack was still a priority because this ship needs to be the highest form of naval dementia. On the plus side, our doctrines leave room for stronger than average destroyers as they also get a speed bonus, and its not like destroyer attack that isn't AA, charges, or torpedoes really means anything so the speed I'm happy calling a win. Not too sure if we want them actually screening, its more like they are dedicated fast submarine hunters. (I'd need to study how screen without screen works more intimately to decide whether these destroyers are actually worth it.)

Agartha Class - Super Heavy Battlecruiser

The Agartha-class battlecruiser represents a triadic union of Speed, Firepower, and Armor. Only the boldest and most ardent navies can adopt such a weapon system and integrate it into a doctrine tempered by an iron will, as resilient as the armor of this titan itself. The Agartha-class battlecruiser has been designed to perform both strike force operations and active patrol and engagement missions, thanks to the inclusion of two seaplane catapult systems that enhance its reconnaissance and operational flexibility. Its prohibitive cost demands long-term access to strategic resources and almost odyssean construction times; these factors tend to make the design unattractive to minor nations or to those unwilling to draw strength from the virtue of patience. Nevertheless, those capable of investing in the Agartha class will stand at the forefront of the world's naval powers. Grand Doctrine: Fleet in Being Doctrines: The New School Fast Battleships
