What stats would you give a rail-gun?


Recommended Posts

So a space ship rail gun 

A small one firing a 4kg to 10kg sug from 12000 km/h to 24000 km/h we can already do this.

A large one 50kg to 200kg  sug from 40000 km/h 60000 km/h

At 200kg 60000km/h would have 28,900,000,000 joules of  kinetic energy this is  Kinetic energy of an Airbus A380 at cruising speed (560 tonnes at 562 knots or 289 m/s)

What damage would you give ?

The stats for railguns were included in BRP Mecha. M-Space is intentionally compatible with Mecha, so they should be still ok.

A 120mm gun (25kg shell mass) does 1d8 for conventional gun, 1d10 for a railgun. The damage is on the same scale used by Space.

A 300-400mm gun (shell mass much bigger than 200kg) does 2d8 for a conventional, USS-Iowa style shell, 3d6 for a railgun. At this size these are supposed to be HE shells, but you can assume that a railgun might do the same amount of damage with an AP slug.

The stats for naval guns will be released in the Revolution SRD next week. To obtain a railgun, which will not be mentioned in the SRD although the data is still compatible, shift one row down on the ballistic weapon table.

Well... it's relative, isn't it?  I mean, once you get past about .93c, the mass-dilation hockeystick makes Einstein even more deadly...  ;-)

Not to mention how friggin' HARD it is to take defensive responses when the attack comes so hard on the heels of you seeing the attack launched!

Relativistic Kinetic Weapons ftw...

Part of the reason U.S. Navy and  British Navy are so excited about railgun technology. Is if your there  enemy getting hit Buy 200 kg tungsten carbide slug at 14000 km/h from 440 km out for the cost of $20k and do twice the damage of 2.5 million $ Cruise missile has to suck.

Its great until your 10th shot and need to replace your heat eroded barrel at the mere cost of $5 million. ;)

They shouldn't be. A British Rail gun would always be late, serve crappy sandwiches, cost a fortune, constantly go on strike, and not bother stopping at lesser targets,

(I really don't expect anyone born after 1980 and in a non-British country to get this joke)...

Sounds like Australia, except with more whingeing :D
