PHASED PLASMA GUN

The standard appendage-held projectile weapon of many races. While slugthrowers are cheaper to manufacture, they are impractical in a space environment. The PPG fires a packet of superheated gas, usually helium, instead of a metal slug which could rupture the hull of a ship or space station. When firing, the PPG heats a portion of gas stored in the gun's removable energy cap.

When the gas is in a plasma state, it is "fired" down the barrel of the gun by the sequential activation of electromagnets in the barrel. After firing, the plasma packet retains its coherence from a residual magnetic field surrounding it. Upon impact, the magnetic field is broken and the plasma energy is released. As with most weapons, time and distance weakens the field, reducing the effectiveness of the shot. The most effective defense against PPG fire is pure berillium, which causes the plasma to ricochet.

 PPGs are constructed from very durable alloys that can withstand the stress of the extremes of temperature from repeated use. The electromagnetic firing coil is made from a morbidium alloy, which is harder than a diamond. Supermorbidium (the 156th atom) was discovered in 2259. Its use in PPG weaponry has been very low due to high costs in creating this element. PPGs manufactured in Earth Force territory have a serial number stamped on the morbidium coil during manufacture to allow the weapon to be traced easily. Special agents within Earth Force are issued unnumbered PPGs.

 As with slugthrowers, Earth-made PPGs are available in many forms:

Other species have their own version of the PPG with sometimes large variations in power, recharge time, design aesthetics, and ammunition capacity. [NOTE: Prices listed are "suggested retail." While many weapons are restricted to certain groups, fixers (such as n'grath) are more than happy to supply a needed item for up to five times the list price.]
