Spacecraft Systems

Armor Systems
The following armor systems are available in the setting: Ice (SS1:11), Stone (SS1:11), Iron (SS7:6), Steel (SS1:11), Light Alloy (SS1:11), Metallic Laminate (SS1:12), Advanced Metallic Laminate (SS1:12), Nanocomposite (SS1:12), and Diamoindoid (SS1:13). Ice and Stone are most commonly encountered in bases built inside of or designed to look like comets and asteroids, respectively. Light Alloy and Metallic Laminate are usually used in the manufacture of civilian spacecraft, while Nanocomposite and Diamondoid are normally encountered on military vessels.

Atmospheric Systems
Certain systems aren't likely to be found in this document as systems for spacecraft, but are still used in the setting for purely atmospheric craft. Most atmospheric craft in use in the Sol Sector use Contragravity Lifters (SS1:14) and some form of propulsion, and don't exceed SM +8. The Afterburning Turbofan (SS7:10), Gasbag (SS7:9), Helicopter Rotor (SS7:10), Jet Engine (SS1:19), Fusion Air-Ram (SS7:10), Maneuver Enhancement (SS7:11), Ornithopter Wings (SS7:12), and Turbofan (SS7:10) are all available for purely atmospheric craft.

Reaction Engines
The most common reaction engines are the Fusion Torch (SS1:23) and Plasma Torch (SS7:16), the latter usually operating in a low-thrust, high-efficiency mode. The Super Fusion Torch (SS1:23) has just been invented, but has yet to reach full production; it may, however, be found on certain unique experimental craft. The Fusion Torch and Plasma Torch engines are often built for aerospace operations with the Ram-Rocket option (SS1:30).

Reactionless Engines
The Rotary Reactionless Engine (SS1:24) may not be placed in a Central hull section. This engine otherwise resembles the Standard and Hot Reactionless Engines (SS1:24), but designed for very low thrust.

The Super Reactionless Engine (SS1:24) has not yet been invented.

All Reactionless Engines are given the Waste Heat Signature setting switch (see below). In addition, they are all pseudo-velocity drives, producing pseudo-velocity thrust equal to 10 mps times their acceleration in G.

Space Sails
Many pleasure craft or scout craft may be encountered using a sail system in the area inside a system's snow line. While the Lightsail (SS1:25) is the most common, the Magsail (SS1:25) and Radioisotope Sail (SS7:17) systems are also available. Most of the time, these systems are found on pleasure craft used by the idle rich. In fact, a lightsail race is held annually at the Nantucket station in the Procyon system.

Lightspeed and Stardrive Engines
The only Stardrive Engine (SS1:25) available is a hyperdrive. Unlike the model described in Spaceships, additional hyperdrives do not increase speed; instead, a second unit may be used as a backup drive. The most common speed for a hyperdrive is 6 lightyears per week, although this can optionally be boosted by one additional lightyear that week for every point of a margin of success on the Navigation (Hyperspace) roll. The effective maximum speed at which organic life can survive is five lightyears per day (35 lightyears per week).

The Lightspeed Drive (SS7:11) is also available, but rarely seen outside of antiques dating back to the Human-Pondrur Wars.

Weaponry Systems
The following beam weapons are available: Laser, Electromagnetic Disruptor, Particle Beam, Plasma, UV Laser, Antiparticle, Tractor, and X-Ray Laser. The Electromagnetic Disruptor is usually called an "Ion Beam" or "Ion Cannon". The most common weapons used are the Improved Particle Beam, Improved Ion Cannon, and Improved UV Laser; Tractor Beams are not uncommon as well, but usually only see use by and against pirates and smugglers.

Electromagnetic Guns and standard Missile Launchers are also available in the setting; missiles are much more prevalent than guns. Warp Missile Launchers (SS1:29) are not available.
