Type SB class System Defense Boat

The Type SB class System Defense Boat is a defensive warship.

Description (Specifications)[edit]

System Defense Boat (Type SB): Using the type 400 hull, the system defense boat is equipped with ten staterooms (…allowing a crew of ten); no low berths are fitted. The crew consists of a pilot, navigator/medic, chief engineer and five engineers, and two gunners. The ship has drives capable of 6-G, but no jump capability. The bridge has a very powerful Model/5 fib computer, with standard software package. Four tons of turret fire control are allocated— two triple missile turrets and two triple laser turrets. The hull is streamlined and heavily armored. [1]

The total cost for a system defense boat of this type is MCr777.54. [2]

Ship Interior Details[edit]

Interior Details: The entire system defense boat is fitted snugly into an alloy hull with compartmentalization for the various ship functions. Fuel buffers surround the ship for greater damage control. Mounted aft are the drive room and the maneuver drives for the ship; integral power plants are included. Occupying the center of the ship are large missile magazines which hold additional ammunition for the ship's missile racks. Above and below are laser turrets, but the gunner couches for all weaponry are hidden within the ship on the lower deck (21 and 22). [5]

The upper deck contains the bridge and access points to the various missile equipment. It also contains lateral air locks for access to the exterior. [6]

The main deck, sandwiched between the upper and lower decks, contains crew quarters, a galley (4), and a common or recreation area (8). [7]

Variant Models[edit]

Variants: A wide variety of system defense boats exist, ranging in tonnage from 100 to 1,000 tons, and in tech levels from 8 to 15 and above. The ship illustrated here is only one of many different types. [8]

History & Background (Dossier)[edit]

THE SYSTEM DEFENSE BOAT: The term boat means a non-starship, whether a gunboat, a ship's boat, or a system defense boat. Because non-starships can allocate more tonnage to power plants and weaponry, they can usually defeat a starship of equal tonnage. From this principle, the concept of the system defense boat has evolved. Fleets of such boats are stationed in important systems and charged with their defense. From stations in orbit, they defend the primary world. From stations deep within the local gas giant, they attack enemy ships in the process of refuelling. In extreme situations, they can scatter and hide, in asteroid belts, on airless worlds, and in the depths of oceans; later they strike out again, hitting the enemy from the rear or when least expected. [9]

Finally, such system defense boats are also used for routine duties such as customs inspections, piracy suppression, and search and rescue. [10]

Because SDBs have no jump drives, shifting them from system to system can be a problem. Some types have jump shuttles which fit to the craft and provide jump capability. Another method is simple transport in large bulk cargo carriers; the SDBs are loaded into 10,000-ton or 20,000-ton bulk carriers for the multiparsec journey. This method, of course, is not recommended if immediate combat is expected at the destination. [11]

Class Strategic Deployment[edit]

Employment: The system defense boat is used by most stellar systems which are vulnerable to attack or which consider that they have something which is worth defending. In general, a few system defense boats are visible in such a system for show; the majority remain on station for long periods of time and return to a planetary base only after being relieved. [12]

Typically, SDBs are deployed in five general areas: the comet belt, the gas giant, the asteroid belt, near the major world, and on the major world. [13]

System defense boats in the comet belt are in deep reserve, committed to attacks on invading ships if possible and to guerrilla-type raids if the invader succeeds in entering the star system. [14]

The local gas giant is another site for SB deployment. Boats are actually placed deep within the gas giant itself, and are poised to attack enemy ships in the process of refuelling. Even if invading ships then succeed in taking the region of the gas giant and establishing a refuelling foothold in the system, they must still contend with system defense boats lurking within. [15]

The asteroid belt provides camouflage for system defense boats, allowing them to lie quiet and unmoving for long periods of time. When enemy ships present themselves, the boats can dash out for the kill and then retreat quickly to the protection of the belt. Caches of supplies and fuel are often prepositioned in the asteroid belt for later rendezvous by system defense boats. [16]

The remaining system defense boats in a system are positioned around the major world. Many of them occupy close orbits and are routinely committed to anti-smuggling duties; additional boats are assigned to far orbit and maintain safety or rescue operations. The remainder are on long-term station on the world itself itself. If the world has any large bodies of water at all, the system defense boats stationed on it will be based in the water. Because this water is reasonably opaque to most sensors (…and thus provides ready concealment), system defense boats stand on station in the ocean depths, often connected to in-place sensor arrays or alert systems. They are hidden until needed; they are ready to act at a moment's notice. By necessity, system defense boats are built to take the pressures of ocean depths and to operate without problems in such environments. [17]

Class Naming Practice/s & Peculariarities[edit]

Peculiarities: While the naming practices for these vessels is far from uniform, a good number of the classes are named after mythical beats, legendary monsters, and cryptids. Many such creatures have turned out to be repitllianoids, or creatures with reptile-like characteristics. The Dragon class System Defense Boat is the class leadrer and namesake of such defensive vessels. [18]
