The KA25c Growler class Tanker is an TL–12 Tanker. It is a development of earlier tankers with lower Jump potential.


The Growler class is an auxiliary vessel of the Korsumug Empire and operated by the Imperial Korsumug Navy, based upon a Jansa design and crewed by Jaibok.

Examples of the class serve with the Glorious Triumph Fleet.

General Description[edit]

The Growler class is an auxiliary tanker with 2-G and J-3 performance. It is a large, slow ship, equipped with strong sandcaster defenses and laser turrets most commonly used in a point defense role. The design is fully streamlined, giving good atmospheric performance and enabling it to perform surface landings.

Basic Ship Characteristics[edit]

Following the Imperial Navy and IISS Universal Ship Profile and data, additional information is presented in the format shown here. The small craft factor indicates the number of squadrons (...of ten subcraft) carried on the ship. Tonnage on the universal ship profile is shown in kilotons (...thousands of tons) where necessary.

Basic Ship Characteristics [2]
No. Category Remarks
1. Tonnage / Hull The KA25c Growler class Tanker is constructed using a 2,500 dTon hull built in a generally conical configuration. The hull is streamlined and has good atmospheric capability: its atmospheric handling characteristics are improved by its onboard gravitic systems.
2. Crew x34 personnel.
  • x11 command, x5 engineering, x6 gunnery, x4 flight, and x8 service.
    • The command crew consists of the Captain, the Executive Officer, two electronics officers (commo and sensor ops), two pilot/navigators, three fuel control officers, an admin officer, and a medical officer.
    • Each crew section has a senior officer.


  • There are 22 Staterooms.
    • Staterooms are configured to what the Jaibok consider to be comfort.
    • All Staterooms are given over to the crew. 10 are single occupancy and are set aside for selected command personnel and senior staff: the remaining 12 are double occupancy.

Accessible areas of the hull are fitted with grav plates and inertial compensators and have full life support and environmental systems.

  • There are internal monitoring and security systems throughout the vessel. Individual sections of the hull can be sealed off.
  • There are multiple emergency lockers.
3. Performance The vessel mounts a Jump-3 drive, a Maneuver-2 drive, and a fusion Power Plant-3, giving performance of Jump-3 and 2-G acceleration. The ship has an agility rating of 2 and an emergency agility of 2. The internal fuel tankage is sufficient for One Jump-3 and gives the power plant 4 weeks duration.
  • The engineering section has a main control room.
  • The jump drive utilizes a hull grid.
  • The jump drive is fitted with a jump governor.
4. Electronics Adjacent to the bridge is a Model/4 fib computer. A backup Model/4 fib is installed in engineering.

The vessel is fitted with communications equipment, a sophisticated sensor array, and has an avionics suite.

5. Hardpoints x25 hardpoints.
  • The listed weapons systems are typical for the class.
6. Armament The normal weapons fit-out for a Growler class is:

x5 triple Beam Laser turrets, forming one battery of 5 linked turrets.

7. Defenses The hull has no additional armor.

x20 triple Sandcaster turrets, forming two batteries of 10 linked turrets.

  • The vessel is not fitted with screens or other passive defensive systems.
8. Craft Flight Section:

x2 10-dTon KU1a Fetch class Launches.

The subcraft are housed in a dedicated hanger: the hanger can be sealed and has a total volume of 26 dTons.

9. Fuel Treatment The vessel has internal fuel tankage of 825 dTons.

The vessel has refuelling tankage of 950 dTons.

  • Fuel transfer is done via boom arms that extend from the hull.
  • Vessels attach to these and draw fuel from the tanker's refuelling tanks.
  • Up to four vessels can be refuelled simultaneously.
10. Cost The basic cost of the vessel is MCr1,592.192
  • Architects Fee: MCr15.922
  • If multiple examples of the design are ordered all vessels in the production run qualify for a 20% discount, which reduces the price per unit to MCr1,273.754

The price does not include the cost of the launch:

With its subcraft, a discounted Ancestor class costs MCr1,283.610

11. Construction Time 204 weeks as standard, 184 weeks in bulk.
  • Build times can be reduced by mass production and the efficiencies such processes generate, by increased financing, and by allotting additional yard resources and facilities to the construction contract.
12. Comments Standard cargo capacity amounts to 21 dTons.

History & Background[edit]

The Growler class tanker is a common type of auxiliary used by the Korsumug Empire, typically serving as a major support vessel within a patrol force or a raiding group. Examples of the class can be encountered throughout Mavuzog Sector and Theta Borealis Sector.

The type was designed by the Jansa, a minor race closely allied with the Jaibok.

Early low-jump examples of the class served on the Korsumug Main, where they saw frequent active service. A number of redesigns with more powerful drives were fielded as the Korsumug Empire began to venture to worlds further from the Main. This ultimately resulted in the KA25c variant, equipped with a Jump-3 drive, though at the expense of reduced fuel tankage compared to earlier versions.

  • Growler class tankers frequently operate as support vessels for Jaibok raiding groups.
  • Growler class tankers often pair with a Gravid class Carrier.

Class Naming Practice/s & Peculiarities[edit]

Vessel Peculiarities:
The design is capable of independent operations and can transport incidental supplies in their small holds. The vessel is primarily equipped for defense and is rarely seen without an escort, typically a Gravid class Escort Carrier, along with its protective screen of fighters. The Growler in turn provides the carrier with refined fuel.

Physiologically, neither Jaibok nor Jansa cope well with low berths and they are not routinely fitted to Korsumug vessels. Earlier variants of the class were fitted with low berths in order to transport prisoners, a feature that has been removed as internal space issues have become more pressing.

Class Naming Practice/s:
Vessels of the Korsumug Empire are given alphanumeric designations and callsigns by other interstellar states. KA refers to Korsumug EmpireAuxiliary (a designation applied to all Korsumug support units), 25 is a multiple of hundreds of tons of displacement and also indicates at a glance the number of weapons mounts, and 'c' refers to the version of the vessel, relating to its construction tech level and bracketing its maximum jump potential. Type codes will often repeat: 'Growler' is an easy to remember name to help with rapid identification.

Individual vessels are generally named by their crews.
