The Arden class System Defense Boat is a defensive warship and a bigcraft.

Description (Specifications)[edit]

The Arden class System Defense Boat is a heavily armored military bigcraft used by the defense forces of Arden, an important neutral system in the Spinward Marches. It is a rugged, reliable design that has seen much action and is well liked by its crews. The Federation of Arden is believed to operate at least four of these vessels and a number of additional completed hulls have been exported to neighboring neutral worlds.

  • The vessel is a TL-8 design.

General Description[edit]

The Arden class is a flattened streamlined wedge with a mean width of 48 meters, a mean height of 25 meters, and a length of around 90 meters. The ship has a total enclosed volume of approximately 39,150 cubic meters. The hull is solid and extremely thick, though there are access and maintenance spaces, and almost half of the internal volume is given over to machinery and fuel. The vessel is a tail lander: the decks within the vessel are arranged vertically and are accessed by elevator shafts. The bridge, the computer and the electronics are forward, accommodations are located centrally, while the cargo hold is located aft and is at ground level when the vessel is landed. The avionics bay and computer room are spacious and can be accessed.

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. [1]

Basic Ship Characteristics [2]
No. Category Remarks
1. Tonnage The Arden class is constructed using a 2, 900 Ton hull built in a wedge configuration. The hull is streamlined and has good atmospheric capability: its atmospheric handling characteristics are heavily reliant on its onboard gravitic systems.
  • Individual sections of the ship are divided by bulkhead walls.
  • There are x2 personnel airlocks. The cargo hold is accessed by doors and has a loading ramp.
  • The design is a tail-lander. The vessel has sturdy retractable landing legs located in the stern, allowing surface landings.
2. Crew Total Crew Complement: 46 (x10 Officers, x36 Enlisted).

There are x29 Staterooms.

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. Sections of the ship can be isolated in the event of an emergency.
  • There are multiple Emergency Lockers.
3. Performance The vessel mounts a Maneuver-5 drive and a Power Plant-7, giving performance of 5-G acceleration and producing 203 Energy Points. The ship has an agility rating of 4 and an emergency agility of 5. The internal fuel tankage gives the power plant 4 weeks duration.
  • The engineering section has a main control room.
    • Ladders, gantries and platforms give access to the machinery.
4. Electronics Adjacent to the bridge is a Model/2bis Computer: there is no backup computer.
5. Hardpoints x29 hardpoints.
  • The listed battery groupings are considered standard for the class. Alternative battery groupings may be designated for specific missions.
6. Armament The normal weapons fit-out for an Arden class is:

x1 100-Ton Bay mounting a Particle Accelerator.

x1 100-Ton Bay mounting a heavy Missile launcher.

x5 triple Pulse Laser turrets, arranged as five independent batteries each consisting of a single turret.

7. Defenses The hull is plated and structurally reinforced, with an armor rating of 8.

x4 triple Sandcaster turrets, grouped into one battery of 4 linked turrets

The vessel is not fitted with screens or other passive defensive systems.

8. Craft The ship carries no subcraft.
9. Fuel Treatment The vessel has internal fuel tankage of 203 dTons.
10. Cost The basic cost of the vessel is MCr4,194.800.
  • Architects Fee: MCr41.948
  • If multiple examples of the design are ordered all of the ships in the production run qualify for a 20% discount, which reduces the price per unit to MCr3,355.840.
11. Construction Time 132 weeks (33 months) as standard.
  • 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 50.0 tons.

History & Background (Dossier)[edit]

This vessel is a streamlined needle/wedge configuration hull to provide defense versus meson armed combatants. The hull carries as much armor as possible the only other defense is four triple sand caster turrets grouped as a battery. A set of five triple pulse laser turrets can target up to fifteen targets to blunt missile strikes and fend off fighters. The major weaponry is a pair of massive weapon bays. One is allocated for missiles and the other is a particle accelerator. The 5G main drive allows fair agility. The model/2 bis computer is seen as a tactical limitation. There is a large fifty ton cargo bay that allows some flexibility. Extra troops, vehicles, and supplies can be moved around the system to support defensive operations needed to maintain the system's strict neutrality.

The Federation of Arden builds and maintains as large a system defense force as it can afford. The linchpin of the Federation Defense Fleet is a class of large system defense boats which strain the local TL–8 ship building capabilities. Despite it's lower Tech Level (TL-8), it often rebuilt with modernized ship weaponry (...typically to a TL:13-15 standard) and are still often a potent threat, even to top-of-the-line warships.

Class Naming Practice/s & Peculiarities[edit]

Arden-class vessels are typically named after great generals or admirals from nearby mainworlds.
