This OXP adds a new class of weapons to the Ooniverse. Railguns fire high velocity kinetic projectiles which are destructive simply by impacting on their target.
Fauchon-Oliphant Inc., producers of high-powered electrical coils and appliances, proudly present their newest contribution to advanced weapons technology: the Fauchon-Oliphant X-series of precision railguns.
The basic principle of railguns has been known for centuries: a strong electric current sent through a pair of metal rails accelerates a conductive projectile to speeds much higher than achievable by propellants like in missiles. The Fauchon-Oliphant X-series operates with kinetic projectiles: there are no explosives involved, the damage to its target is dealt purely through the kinetic energy of the impact. The lack of explosives makes at the same time the projectiles perfectly safe for storage on a space ship.
Currently the Fauchon-Oliphant X-series of precision railguns consists of three different varieties: The X-100 Small Railgun, the X-150 Medium Railgun, and the X-200 Heavy Railgun. Their basic difference lies in the different composition of the projectiles. The heavier projectiles yield more destruction on impact, but the gun needs more time and energy to recharge. While the X-100 allows for an almost continuous firing rate of its lighter projectiles, the rate is noticeably slower for the X-150 and the X-200. The prodigious amounts of energy needed to create the electric current means that with all weapons the user should have an eye on their energy banks. As an added safety measure the guns will shut down if there is only one full energy bank left.
Each of the railguns needs its specially manufactured projectiles. These are available in bundles of 100 at your local equipment department of at least techlevel 3. The railguns themselves can be fitted in stores beginning with techlevel 4 for the X-100 Small Railgun.
Fauchon-Oliphant Inc. guarantee the efficacy of all their projectiles up to a range of 20 km, independent of the type of projectile. Above this range the projectiles tend to dissolve due to the increasing friction with the surrounding phlogiston.
For civilian use Fauchon-Oliphant Inc. is also proud to present the new Z-series of mining railguns. Currently this consists of the Z-300 Mining Railgun. While the basic principle is the same as for the X-series, the projectiles of the Z-300 Mining Railgun are much heavier than even the X-200 Heavy Railgun projectiles, and they are fired with a much slower velocity. This—and the enormous energy and time needed for recharging the gun—makes them practically useless as weapons against moving targets, but a very powerful tool for asteroid mining. Two projectiles should be sufficient to crack all but the biggest asteroids, and another one will usually knock a couple of valuable splinters from the resulting boulders.
The higher mass and density of the Z-300 Mining Railgun projectiles made it possible to increase their effective range. Fauchon-Oliphant Inc. therefore guarantees their functionality up to a full scanner range of 25.6 km. The downside of their increased mass is that one bundle only contains 50 projectiles, and is a little more expensive than the bundles for the X-series.
All railguns are mounted close to the front laser of your ship and fire their projectiles strictly forward. They are currently not available for other orientations. All railguns need to be activated first (default key 'SHIFT-N'), before they can be fired (default key 'N'). A message informs the pilot how many projectiles are left in the magazine. When all projectiles have been fired, the gun stops working until the pilot has re-filled the magazine.
Railgun.oxp v 1.1 requires at least Oolite 1.75.1.
Railgun.oxp v 1.2, which includes the mining variant and many more improvements, requires at least Oolite 1.75.2 (or the current trunk). It won't work with Oolite 1.75.1.
Railgun.oxp v 1.1 is available for download via Box.net.
Railgun.oxp v 1.2 is available for download via Box.net.
Move or copy the file railgun.oxp from its download folder into your AddOns folder. Where that resides depends on your installation. Restart Oolite.
