The Imperial Navy has decided that its Ryuho and Sabre class ships have seen their finest days. In line with the submarine force modernization, both the Ryuho class BCGN and Sabre class DDKN are to be replaced with newer hulls that will better serve the fleet. The Tenchu class will take six years per ship to build and be built in two 108-ship blocks at a cost of 702 billion USD per block. The Morningstar class will take four years to build per ship and will be built in four 162-ship blocks at a cost of 648 billion USD per block. Construction will begin when the new submarines complete.
Tenchu class Guided Missile Battlecruiser
Displacement: 75,000 tons tons
Dimensions: 330M L x 70M W x 10.4M D
Propulsion:
2 x Ascension Nuclear Type-3 Pebblebed reactors rated at 175Mw each
6 x Water jets
Speed: 40+ knots (top speed)
Crew: 550
Endurance: Limited to crew endurance only.
Radar:
APAR-12E Mod 2 Air/Surface (Long Range Air/Surface Search/Targeting)
APAR-SX Mod 1 Air/Surface (Medium Range Air/Surface Search/Targeting)
AS-35 Mod 0 Airborne Early Warning (Long Range Air Search/Tracking)
Iris Mk1 Mod 1 (Medium Range Over-The-Horizon Search/Targeting)
Zeus Mk1 Mod 0 (Long Range Over-The-Horizon Search/Tracking)
Akarigan Mk1 Mod 1 (Short Range/CIWS Air Search/Tracking LIDAR)
G04 Navigation (Short Range Surface Tracking)
Fire Control:
Falltech GSWDC Control Bloc (Ship Control)
Falltech "Jupiter" (Area Warfare Coordination)
Falltech NG05 Mod 2 (Gunfire Control)
Ryugi Multilink Combat System
EW:
Mk603 Intercept/Jamming Unit
4 x Type 5 MR Chaff/Flare Dispensers
SLQ-25A Nixie torpedo countermeasure
Mk53 SRBOC decoy
Host arrays for ELINT equipment
LIDAR/SONAR:
Mk.1B Multi-Spectrum LIDAR
Mk.2A Underwater LADAR
Opal Eye Underwater Self-Defence LADAR
SS-24A Bow-Mounted SONAR
SS-30C Multi-Line Towed SONAR
Aviation: None
Armament:
6 x 10"/60 ETC (Triple Mounts)
8 x 144-Cell Mk72 Strategic Single-Load VLS
2 x 4-cell Mk72 Tactical Single-Load VLS
4 x Oto Melara 76mm/62 Super Rapid ETCs (Dual Mounts)
7 x 25mm BI M/C Cannons
8 x Mk45 CAMDS
4 x Machine Gun Mount
6 x 660mm Torpedo Catapults (24 Torpedoes and 80 depth charges/mines)
6 x 50mm Underwater Supercav Railgun
Armour: 300mm multilayered titanium/vandium/aluminum and ballistic ceramics; interlaced with sensor pads, cooling detergent, and mounted on a honeycomb frame
Design Notes: The Tenchu ("wrath of heaven") class continues the Imperial Navy's tradition of giving battlecruiser classes Japanese names. While the number and type of VLS remains the same, the new 10" guns are a definate improvement over the old 8" weapons of the Ryuho class. Unfortunately a compromise was necessary to keep two turrets and make space for the rear two missile blocks, so the helo hangar and pad were deleted in favor of placing the X turret in that space; it was also necessary to delete two 76mm turrets in favor of the aforementioned missile blocks. An advantage of the new configuration is that the Tenchu class is not as vulnerable to a chain reaction, although the tight configuration of the missiles means that some danger remains. As the ship uses the exact same hull as the Imperial Navy's cruisers, development costs were cut by a large amount and the entire design amounts to a reorganization of the weapons.
Morningstar class Nuclear-Powered Hunter-Killer Destroyer
Displacement: 45,000 tons
Dimensions: 265M L x 64M W x 10.5M D
Propulsion:
2 x Pebblebed reactors rated at 150Mw each
6 x Water jets
Speed: 40+ knots (top speed)

Armament:
2 x 6.1"/64 ETC (Single Mounts)
5 x 144-Cell Mk72 Tactical Dual-Load VLS
4 x 50mm Underwater Supercav Railguns
6 x Mk45 CAMDS
6 x 25mm BI M/C Cannons
4 x Machine Gun Mounts
4 x 533mm Torpedo Catapults (16 Torpedoes and 60 depth charges/mines)
4 x Mk2 12-Cell Unguided ASW Mortars
Armour: 200mm multilayered titanium/vandium/aluminum and ballistic ceramics; interlaced with sensor pads, cooling detergent, and mounted on a honeycomb frame
Design Notes: Like the Osiris class DDGNs, the new Morningstar class DDKNs (named after the most decorated of the Sabre class DDKNs) are a modification of the venerable Minotaur class DDANs. It was decided to go with the slower ship because the Sabre's speed has largely gone unused and the draft of the fastship hull is prohibitive in littoral waters. The primary modification is in the missiles, where all the 72 cell tactical dual-length VLS blocks are replaced by 144 cell strategic dual-length VLS blocks. Like on the Osiris class the outboard cannon mounts are deleted in favor the larger missile capacity and the two superstructure tactical VLS blocks are replaced by a single strategic block. This is all to make room for large vertical launch anti-submarine rockets that would be needed to boost torpedoes as large as 660mm.
