So total conversion, but say it only runs on Tylium?

Or use Thylium with some other device. If you put in limited gravity control, you can live with lower amounts of G to get out of a gravity well.

You end up with short burn durations, but then the Viper IS not a long range fighter, much like todays fighters.

The thing I am uneasy about the total conversion drive is that it is TL12^ and has a delta-v of 10,000 for each fuel tank. What about using a Fusion Torch drive and have it with high-thrust? With the 4 fuel tanks, it would get a delta-v of 90 mps. Maybe tack on an additional fuel tank or 2 and make it use water (Thylium in this case) for triple thrust.

Mk VII's also have a third gun, attached to the top fin.


Also, Vipers of both types have slots for missile attachments (max 2 I think) under their wings.

The major battery allots for up to three weapons anyway. The VII's loose the internal missile launcher, right? In that case just swap it for a third gun.
I don't think hardpoints have really been covered in Spaceships. Although, since it IS a mass-based system it shouldn't be hard to work out numbers.

Everyone keeps saying the viper uses fixed railguns, but on one of the first couple seasons there was an episode where someone was sabatoging the ammo the Vipers use. They held up one of the shells and it looked alot like a 20mm round to me. Am I Wrong here? Pretty sure its not a rail gun. Of course how there is an atmosphere system to allow combustion for a round requiring ignition is up to you guys, but I am pretty sure the vipers use 20mms or similar auto cannon rounds dont they?

Because they use railguns as per tech spec. Welcome to the wonderfull world of movies - somehow obviously just thouht it is ok to use 20mm ammunition as railgun ammo ;) I also think the ammo shown was too big - no clue where they fit hhundreds of those rounds in that tiny fighter ;) But then, it is a movie - sometimes glitches happen.

No round of a current weapon uses the ammunition for ignition, you know. How could they - iven that the curren ammo is in a sealed barrel anyway? The oxidant is always enclosed with the explosive mass, even today, even in a shotgun, revolver or any other weapon. They all would work in vacuum - maybe not often (there are issues, but they are not about "makin it go boom").

Viper ammo is casingless. The round is ignited like a real world bullet round, but instead of the round jettisoning its casing at firing, it takes it along for the ride. Its not exactly a rail gun, it just a high rate heavy machine gun, though it may have some magnetic assistance too. The Galactica has rail guns however.

Wrong. The Vper uses a Railgun, termed "Mass Accelerator". I suest you read u the technical specs (like for most science fiction series this is published somewhere - just use google).
if you trust in Wikipedia (which quotes the official season 1 companion book, which you can get at amazon) it states these are mass drivers, each (in the Mark II) with 800 rounds ammunition (which I do not see fitting into the wings, given the size of a round shown) and 20 rounds per second firing rate. 40 Seconds of fire - not exactly that much. Now, the definition of a mass driver is pretty clar - it is a railgun. Production obviously wanted to produce some problems with the ammunition (hard to do with mass drivers) and thus "changed" that to be "classical" gun ammunition for an episode. And then reused some ammunition they could get cheaply their hands on, without consulting how you would fit 800 of those into the tiny wings. Nothin serious here - just a small oversight in a TV series that is meant for entertainment.

Ever tried to get your facts verified before posting them? You are not even consistend:

Caseless = no case.
No case = nothing you can take along the ride.

This makes no sense, just from a logical point of view. The whole pioint of caseless ammo is that there is no case, so you dont have to get rid of one (and save the weight). As a result, the case could not be "taken along for the ride".
