Misha-Class Explorer

The Misha-Class1) Explorer represents ships in a class lineage made by the Yugumo Corporation. The first (1A) version of the ship debuted in YE 42, with a (1B) rebuild in YE 43 and a (1C) refit in YE 44.

Misha-Class Explorer


For a design that started in YE 42 as a way to use up the carcasses of old Motoyoshi Fleet Yards vessels that were left to rot in orbital fleet yards around the Jiyuu System it has done very well for itself. The design ethos came from a need to see a small-scale affordable vessel that would be somewhat fast, and capable of long-ranged operation for a long duration.

The original 1A version produced in YE 42 was made from the conversion of leftover, salvaged, and stockpiled Ayana-Class Escort, so its production was limited. The Yugumo Corporation having success with the design such as the ISS Shiori and the ISS Mitsu decided that the ship would be a perfect multi-role vessel for their corporate fleet.

In YE 43, the Misha-Class Explorer 1B became a reality. The Yugumo Corporation would place the new version of the vessel into full production no longer using salvaged or converted parts. They would also include the modest addition of weapons so that the ship would be equipped for its new multi-role position in the Corporate Fleet. The ship would continue to carry the role of explorer, but it would be additionally tasked with duties such as transport of Yugumo Corporation representatives, small-scale anti-pirate defense, and escort duties in industrial formations.

The Misha-Class Explorer would see yet another upgrade in YE 44 to the 1C which would further enhance features designed for the Misha-Class to become a child-craft to some larger ships like the Tanya-Class Expeditionary Heavy Cruiser and Port Jiyuu as a functional part of the Colonization Initiative Alliance fleet.2)

Now with three consecutive years of improvements, the Misha-Class was set to become a symbol of the Yugumo Corporation.


The Misha-Class Explorer has become a popular craft, not just for customers, but utilized in the Yugumo Corporate Fleet it has become a mainstay part of Yugumo Corporation operations.

Inside the Ship

The Misha-Class Explorer is a comfortable and economical craft. It is equipped with extra cargo space and lots of room to store vehicles and equipment for planetary excursions and even planetary pioneering. The 1B refit and 1C refit would keep the same deck layout as the original ship.


The Misha-Class Explorer is a four-deck vessel, it is equipped with facilities to fit adventure and travel. Wing access is gained through engineering on Deck 3 and from the exterior of the vessel when it is landed or in the dock.


Below is a listing of compartments aboard the Misha-Class Explorer.

Deck 1

The first deck of the Misha-Class:

Observation Lounge

Deck One consists of the large dorsal pod in the Misha-Class Explorer's design. It is dominated by a large observation lounge with panoramic views through Transparent Durandium windows. Depending on the customer, different chairs and seating arrangements are available and a dance floor, swimming pool, or hot tub can be installed upon request. There is a staircase that leads down to the lower decks of the ship here.

Communications and Sensors Package

The aft part of the observation deck has access controlled sealed room where components for the KAIMON Kagami (1B and later) or Explorer Add-On Package (1A) are housed.

Deck 2

The second deck of the ship.

Escape Pod Bank and Bridge Hall

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.

1C Escape Pods

Has been upgraded to utilize sixteen "Ikigai" Type 43 Escape Pod, arranged in an eight-by-two configuration and are launched through diagonal tubes that emerge just to the side of the observation pod.

1A and 1B Escape Pods

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 of the Misha is designed for that one Minkan that just wants to play Star Army of Yamatai. With two seats at each console except the command station, the small six-station-plus-captain arrangement mimics one of the bridge designs used by the Star Army of Yamatai, less the liaison station. Although the bridge comprises multiple stations, the ship is automated enough that it only requires a single operator.

The bridge stations are:

  • Captains Chair and Console
  • Communications and Mission Operations
  • Science/Sensors
  • Systems and Safety Monitoring
  • Navigation and Pilot
  • Weapons Systems and Pilot

Added in 1C Version:

  • Aquatic Steering and Navigation

Present in the 1A and 1B version:

  • Guest

Also in the 1C Version, the bridge includes a “call-down” ladder system to a hatch that leads outside of the ship through the dorsal hull. It is designed for use during aquatic surface operations, and has multiple, redundant, layered failsafes to prevent it opening while in unsafe pressure environments such as at depth or in space or an upper atmosphere, or when the ship is flying above a safe speed. The periscope on the Umikagami's Multifunction Extendable Mast can be operated from just forward of the command station. The ladder is accessed from immediately aft of it.

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, from Nest-style to bunk beds for the children. 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 in 1C and later revisions.


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.

In the event the ship lands on a habitable world, the canopy can be opened via lift mechanisms that move the section of the hull up and back from this compartment.


A small multipurpose room on the ship that is designed to become a small laboratory or infirmary. It comes equipped with lab benches and storage areas and leaves the purchase of equipment up to the vessel's owner.


Located in the bow section of the ship, the workshop is a place for the tinkerer and inventor. It is an ideal space for performing repairs or crafting required tools or accessories.

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 Misha-Class Explorer.

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 that can 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 Misha-Class Explorer spans two decks 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 Misha-Class Explorer 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 in 1C and later revisions.

Computer Chamber

The Computer Chamber is a secured and locked chamber in which the KAIMON (1B and later) or MIKO Core (1A) is housed. Access is limited to the ship's owner and authorized personnel.

Bath House

The Misha-Class Explorer 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 mudding in your favorite off-road toy. 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 in 1C and later revisions.

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 Workshop 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 Ramp 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-in.

1C Cargo One

The 1C revision is outfitted as a Yugumo Standard Cargo Bay.

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 Workshop, 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. When the ship has landed on the surface of the planet, the ramp can be easily lowered to allow easy loading and off-loading of vehicles and cargo.

Deck 4

The fourth deck of the Misha-Class Explorer.

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.

1C Lower Engineering

On the 1C Version of the ship, the lower engineering section will house the guts of the ship's Pump Jet and other Umikagami Subsurface Operations Suite hardware for aquatic surface and below-surface operations. It also includes access to the the ship's ballast tanks.

Cargo Two

The larger of the two cargo areas on the Misha, Cargo Two provides room for more Standard Starship Cargo Containers or other cargo and has access to the ramp 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-in.

1C Cargo Two

The 1C revision is outfitted as a Yugumo Standard Cargo Bay. Below the bay is the ship's bilge.


Below are the systems of the Misha-Class Explorer.

Misha-Class Hull and Frame Construct

The Misha utilizes a primarily Durandium Alloy hull structure. All windows and viewports utilize Transparent Durandium.

Power Systems

Propulsion Systems

The Misha utilizes a modified Mizu II Series - Nami II CDD which maximizes the CDD performance at 18,000c. Distortion coils are located in the wing pods on both sides of the craft.

In addition to the CDD, the Misha is equipped with two Hoshi III Series Multi-stage Turbo Plasma Drives15) for sublight speed. They are located in the central region on the pylons on both wings. Sublight performance for this craft usually can withstand 0.30c. Maneuvering Thrusters (ion thrusters) are used primarily for attitude adjustment, docking, and station keeping.

For hyperspace fold, the Misha uses the Yumeoibito Hyperspace Fold Drive.

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

In the 1C, a Pump Jet16) propulsion system was added for both above and below-the-surface marine operation of the ship. The ship utilizes two ballast tanks to control its buoyancy. Periscopic fin-like structures deploy from the underside and nacelle regions of the vessel when it touches down in the water. The Umikagami Subsurface Operations Suite option further enhances underwater capability.

Integrated Eletronics

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

Additional Sensors (1C)

In addtion to the 1C revision's KAIMON Kagami sensors, there are also a Mineral Scanner and SachiTech Tech-Scanner available to the science officer.

KAIMON Options

The 1C Version is available with the latest KAIMON options from the factory:

Earlier versions may have these systems added as aftermarket refits for additional cost.

Life Support and Environmental

The Misha-Class Explorer is equipped with Yugumo Standard Life Support Systems.


The Misha-Class Explorer'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 two-faced barrier.

Supplementary Shielding

For times when the Civilian-grade 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 real time 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.

Supplementary shielding is available on the 1C and later revisions only.

Electromagnetic shielding

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

Though always adequate, the emergency systems aboard the ship have changed with revisions.

1C Emergency Systems

The 1C version of the Misha-Class explorer was one of the first ships to be equipped with Yugumo Standard Emergency Systems. It has its own fire suppression system and Yugumo Standard Damage Control Alcoves to assist with the repair of damage to the ship.

Yugumo Standard Armory, and Yugumo Standard Survival Lockers easily accessible at key points throughout the ship, all fully-stocked, for any emergency.

Scuba gear has been added to the ship's inventory for both recreation and emergency use.

In the event of a catastrophic failure or impending doom, it is equipped with sixteen "Ikigai" Type 43 Escape Pod.

1A and 1B Emergency Systems

The Misha-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. They are available on the 1C and later revisions only.

Landing Struts

The Misha-Class Explorer is equipped with landing struts, they are pneumatically driven and are used to raise or lower the ship, and level it once it is in place.

In a 1C model equipped with the Umikagami Subsurface Operations Suite, the geometry and countours of the struts are augmented to allow the ship to use them to function as a hydrofoil.

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. Signature reduction systems are available on the 1C and later revisions only.


The Misha'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 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. Utility turrets are only available on 1C and later revisions.


The 1A version of the ship was unarmed. Yugumo Corporation is not responsible for customers who attempt to take this unarmed ship into combat.

The original loadout for the 1B was selected from the ISS Mitsu, a modified version of the 1A version of the ship. Ten multi-purpose mounts are built into the hull of the vessel: two on each wing, two each dorsal and ventral, and one each port and starboard. 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. In late YE 43, the "Taihō" Scalable Mass Driver replaced the the Light Gauss Starship Cannon, and "Tachikaze" Point Defense Cannons Type 43 were fitted to the turreted emitters. The ship can support much more weaponry than the typical loadout sold to qualified customers, or even used internally, but is factory-equipped so as to not be considered a warship. Weapons requiring ammunition store it in a Yugumo Standard Magazine.

A Misha 1C equipped with the Umikagami Subsurface Operations Suite may also mount Chōuryū Subsurface Torpedo/Sensor Platform tubes at additional cost.
