Yūgure-class Merchant Destroyer

A civilian market destroyer-class vessel. Designed to protect the fleet of the Yugumo Corporation. It became available in YE 43.

Yūgure-class Merchant Destroyer

Yūgure (夕暮) is the translation for 'twilight' in Yamataigo (邪馬台語).

History and Background of the Yūgure-class

The Star Army of Yamatai cannot be everywhere and the Kikyo Sector is not free of dangers. Threats to commercial shipping lanes and transit corridors from pirates or the enemies of the Yamatai Star Empire were a reality at the beginning of YE 43. Even if the Star Army of Yamatai managed to end the Kuvexian War, there would likely be hold outs and pockets of resistance for years to come. While the Yugumo Corporation had complete faith in the Star Army of Yamatai, with most of their higher-ranking corporate officers being former officers of the Star Army, the company was required to make a decision to protect its interests and assets as they continued to expand their ventures and other efforts in the sector.

The Star Army of Yamatai career officers of the Motoyoshi Clan were happy to provide input and design oversight for the project. The overall consensus was the desire to create a ship with destroyer capability that kept the design ethos of products the company had launched in YE 42 like the Misha-Class Explorer. In 1月 43年, Ketsurui-Motoyoshi Katsuko stepped in to provide insight into the design. She further stressed the desire for the ship to be more than a defense vessel, but rather another multi-role capable ship for the Yugumo Corporation and its clients.

It was decided early in production that the design would use similar hull schematics as the Misha-Class Explorer. Higher-grade armor materials were used to make the ship more durable in combat. The shuttle bay has been widened slightly to increase accessibility in this design. The weapons designs were influenced by the direction of Motoyoshi-Kotoku Sui, who became Semu of Yugumo Fleetworks in the first month of YE 43.


The Yūgure-class is classified as a Merchant Destroyer. It is designed to be a small, maneuverable ship capable of providing escort to larger corporate-owned vessels like colony ships, agricultural ships, factories; as well as cargo haulers.

Mission Specialization

This ship is ideal for fulfilling the following mission profiles.

  1. Asset Protection and Escort
  2. Anti-Pirate Operations


The Yūgure-class is very similar to the Misha-Class Explorer. It has the sleek maritime-esque hull and the Yūzuki (夕月, ”Evening Moon”) hull paint and texture. Rather than the Misha-Class style catamaran formation for the nacelles, the nacelles are in an in-line vertical formation above and below the hull. The hull profile is designed to be compact to reduce vulnerabilities. The shuttle bay and aft section of the ship are also wider than the Misha design.

Inside The Ship

The main hull of the Yūgure-class uses a very similar shape as the Misha-Class Explorer, so many of the compartments are the same as that vessel.

Deck 1

The first deck of the Yūgure-class:

Observation Lounge and Briefing Theatre

Deck One consists of the observation deck. It is dominated by a large observation lounge with panoramic views (port and starboard) through Transparent Durandium windows. Alternatively, straying from the Misha-Class Explorer, the Yūgure-class has a briefing theatre structure with lounge with chairs and a Volumetric Display.

KAIMON Communications and Sensors Package

The aft part of the observation deck has an access-controlled, sealed room where components for the KAIMON-Gate communications and sensors are housed.

Deck 2

The Second Deck of the Merchant Destroyer.

Escape Pod Bank and Bridge Hall

On the port side of the deck, the three Ge-X3300 - Type 33 Escape Pods are housed. They're designed to be launched through diagonal tubes that emerge just to the side of the observation pod.

The bridge creates an obstruction that forces traffic purposely through the hallway to the escape pods to get around the bridge, as a security measure. In the event the ship has been boarded, the bridge and hallway can be sealed with bulkheads.


The bridge of the Yūgure-class uses the Misha-Class Bridge Module.

Crew/Passenger Suites

The crew/passenger suites are highly customizable. Each suite provides a spacious bedroom, a corner “L” seat, a desk, a closet, and a shower and head bathroom attached. Customers can choose from a variety of bed styles. In some cases, these rooms can be modified into offices or other uses depending on the needs of the customer.

Galley and Dining

The ship's galley and dining room offer a variety of cooking stations such as stoves and ovens, food preparation areas, and temperature-controlled refrigerator and pantry storage. Dining room packages over a variety of tables and seating as well as buffet setups depending on the needs of the customer.

There are Yugumo Standard Housekeeping Closets in this area.


A carry-over from the Misha-Class Explorer. It was left with the expectation that the ship would one day accompany colony fleets from the Motoyoshi Colonial Sector.

A small-scale greenhouse designed for the growing of fruit and vegetables, it includes sprinkler systems, advanced temperature control systems, modified spectrum lighting, and storage areas for fertilizer, soil, and seeds. It was designed with possible survival situations in mind to provide fresh food. Some customers may just want to use this area to garden flowers or other ornamental plants for hobby purposes.


The armory does not come with stock. The customer is expected to purchase their own weapons inventory. It includes a sealed reinforced chamber with Forcefield-Nested Isolation Doors.

Weapons Parts Storage

A storage area is stocked with parts for the ship's weapons systems and minor assembly facilities to assist with installation and repair of these offensive systems.

Shuttle Bay Viewport

At the aft end of the deck, there is a Transparent Durandium viewport which overlooks the shuttle bay below.

Deck 3

The third deck of the Merchant Destroyer.

Shuttle Bay

Located at the aft-most section of the ship, the shuttle bay spans two decks and features a viewport that overlooks the shuttle bay from Deck 2. It has one large door that faces aft. When opened, the force-field-contained opening in the hull can have shuttles exit without creating a vacuum within the ship. The shuttle bay on this ship is relatively small, and can only fit a few small or medium-sized shuttles.


The Engineering and systems compartment of the Yūgure-class spans two decks at the aft of the ship. The upper compartment houses the Mizu II Series - Nami II CDD Control Systems and the Yumeoibito Hyperspace Fold Drive as well as other critical systems of the craft.

There are stairs that lead to the decks above and below in this compartment.


Exploring the frontier can be dirty work. The Yūgure-class has a large laundry facility to solve the dirty problems of most adventurers. There are washing and drying machines as well as tables for folding or stacking clothing and other linens.

There are Yugumo Standard Housekeeping Closets in this area.

KAIMON Chamber

The KAIMON Chamber is a secured and locked chamber in which the KAIMON-Gate Core is housed. Access is limited to the ship's owner and authorized personnel.

Bath House

The Yūgure-class has an expanded Bath House on Deck Three. The Bath House is designed with those who aren't afraid to get dirty in mind. It is the place to get clean after fighting dirty pirates. The Bath House comes equipped with three showers and two bathtubs, as well as a Head for those who need to relieve themselves after those strange, alien, spicy tacos.

There are Yugumo Standard Housekeeping Closets in this area.

Cargo One

Cargo One is the smaller of the two cargo areas. It can fit several smaller-sized Standard Starship Cargo Containers. There is a cargo lift that provides access to Deck 2 (for Weapons Storage Access) and 4 (Cargo Two) to allow for the easy movement of containers and goods. Modular sections can be adjusted to different sizes and placements for straps and other devices to secure cargo are built-in. Cargo One also provides access to the Vehicle Storage Area and Airlock for easy loading.

There is a Scalable Graviton Beam Projector Array in the center of the rear wall, and one in the center of the ceiling, for handling cargo. A pair of cargo grapplers are located on a gantry above, along with traditional cranes and lifts. Modular sections that can be removed or adjusted to different sizes and placements for straps and other devices to secure cargo are built-i

Power Armor Storage

Cargo One has been modified to include a small civilian power armor storage bay that uses the already in place airlock structure.

Vehicle Storage and Ramp

Located in the bow of the ship under the Weapons Parts Storage, the Vehicle Storage Area which is joined to Cargo One provides a great place to store a couple of vehicles, a boat, or other craft for use on planetary excursions. Since this ship cannot land, units have to be dropped or hauled to the surface. This Bay can also be modified to carry 1-2 small civilian fighter ships.

Deck 4

The fourth deck of the Merchant Destroyer.

Lower Engineering

The lower deck of the Engineering compartment houses storage tanks for water and several other systems related to the environmental and life support systems of the ship.

Cargo Two

The larger of the two cargo areas on the Merchant Destroyer, Cargo Two provides room for more Standard Starship Cargo Containers or other cargo and has access to the airlock for easy loading and offloading of goods.

There is a Scalable Graviton Beam Projector Array in the center of the rear wall, and one in the center of the ceiling, for handling cargo. A pair of cargo grapplers are located on a gantry above, along with traditional cranes and lifts. Modular sections that can be removed or adjusted to different sizes and placements for straps and other devices to secure cargo are built-i


Below are the systems of the Yūgure-class Merchant Destroyer.

Yūgure-class Hull and Frame Construct

The Yūgure-class utilizes a primarily Yamataium 1) hull structure. All windows and viewports utilize Transparent Durandium.

Yūgure-class Hull and Frame Assembly
Primary SpaceFrameForcefield Reinforced Yama-Dura Major Truss
Secondary SpaceFrameYama-Dura Secondary Truss and Rod Assembly
Outer PlatesSitearium coated Yamataium Plate with Omnihue matrix
LiningYarvex Lining

Power Systems

The Yūgure-class uses Kaminari Quantum Foam Generatorss with an integrated capacitor system to provide secondary power. Secondary Power can last 2-4 days (non-combat) or 8 hours (combat) in an emergency.

Propulsion Systems

The Yūgure-class utilizes a modified Mizu II Series - Nami II CDD which maximizes the CDD performance at 16,500c. Distortion coils are located in the wing pods on both sides of the craft.

In addition to the CDD, the Yūgure-class is equipped with two Hoshi III Series Multi-stage Turbo Plasma Drives for sublight speed. They are located in the central region of the pylons. Sublight performance for this craft usually can withstand 0.275c. Maneuvering Thrusters (ion thrusters) and the Plasma Projection System are used primarily for attitude adjustment, docking, and station keeping.

For hyperspace fold, the Merchant Destroyer uses a Yumeoibito Hyperspace Fold Drive.

The Yūgure also has an Anti-Gravity System for landing and atmospheric operations.

Integrated Eletronics

The Yūgure-class is equipped with the KAIMON-Gate suite with its included communications and sensor systems. It also has the uplink and PANTHEON/SYNC connect module.

In addtion to its KAIMON Kagami sensors, there are also a Mineral Scanner and SachiTech Tech-Scanner available to the science officer.

Life Support and Environmental

The Yūgure-class is equipped with Yugumo Standard Life Support Systems.


The Yūgure-class's Mizu II Series - Nami II CDD is equipped with a (Civilian) Combined Field System, supplementary shields, and navigational shielding. The primary shields create a six-faced barrier.

Supplementary Shielding

For times when the (C)CFS is unavailable or its operation is undesirable such as when sitearium is energized. Running both supplementary defensive systems at the same time does not increase the effective tier of the barrier, rather, they are used against different threats and the responding selected in realtime after threat analysis by the computer. As the supplementary shields do not contribute to the ship's defensive profile when the (C)CFS is active, it is wasteful to have the supplementary shields active while the primary shields are as well.

Electromagnetic shielding

The Electromagnetic shields are particularly good at deflecting the charged particles in many beam weapons. The shield created is a six-faced barrier.

Gravitic shielding

Gravitic shielding are effective against kinetic weaponry and collisions. This shield also serves the special purpose of counteracting graviton beams. The shield created is a six-faced barrier.

Not intended for, or effective at, defense against starship weaponry, navigational shielding protects the ship against navigational hazards, such as fast-moving small masses and slow collisions with large masses. The deflectors allow for safe maneuvering without raising the profile of its sensor signature as much as the defensive shielding.

Emergency Systems

The Yūgure-class Explorer is equipped with emergency systems that were contracted out to Geshrinari Shipyards. It has a Ge-Y1-E3104 - Automatic Fire Suppression System and Geshrinari Blast Shutters in the event an emergency occurs.

In the event of a catastrophic failure or impending doom, the ship has three Ge-X3300 - Type 33 Escape Pods.

Emergency Lockers

There are more than enough Yugumo Standard Damage Control Alcoves, Yugumo Standard First Aid Lockers, Yugumo Standard Armory, and Yugumo Standard Survival Lockers easily accessible at key points throughout the ship, all fully-stocked, for any emergency.

Signature Reduction

The armor layer is impregnated with an Omnihue matrix, allowing effectively unlimited control over the coloration, pattern, text, and insignia of the surface. This serves as thermoptic camouflage and signature reduction, if set properly.


The Yūgure's armor, in addition to the Omnihue, has layers of sitearium coating it, that allow for even more effectively reduced signature than the Omnihue alone. Note that when the sitearium is energized, acceleration or maneuvering under power, or moving in an atmosphere, disrupts the signature reduction effect, and any zero-point energy such as QF Generator or Aether Generator onboard must be shut down, switching to more traditional forms of secondary power, or the ship remains detectable by anyone looking for such signatures.

Utility Turrets

In various places around the outside of the ship are mounted pop-out turrets for non-weapons systems including the a few of the Large variant of the MultiStruct Multitool for collecting matter and resources from nearby asteroids and debris, several strategically-placed Scalable Graviton Beam Projector Array and articulated grappling arms for manipulating objects outside the ship, and Harpoon Cables, adapted from the Courier 2c 'Collector' for anchoring and towing.


The ship is armed with a Plasma Projection System array comprising various sizes of emitters. These also serve as secondary engines and maneuvering verniers, increasing the acceleration profile, maximum speed, and maneuverability of the ship. Both the point-defense and anti-starship turret systems are pop-up/retractable so during non-combat situations they are enclosed beneath the hull plates. Weapons requiring ammunition store it in a Yugumo Standard Magazine.
