I'm not sure we have anyone on here who used to handle naval shells, especially the larger-caliber ones, but I'm former artillery, so I'm familiar with the concepts. I was MLRS, and if you know much about missiles, you know that MLRS has two types of rounds - the smaller 227mm round, there are six per pod. The larger ATACMS has one round per pod and is 610mm caliber. Actually, the ATACMS missile (at 4m) could roughly be considered similar to a Traveller Torpedo round (AFAIK no dimensions are out there for a torp round, just the displacement...anybody know any different?). It's a bit shorter than a Trav torp, but seems to fit the bill better. Size-wise, the old Honest John rocket is approximately the same size given for a torp (length wise at least, we don't know how wide one is).locarno24 wrote:True, but I can just about buy into a 50 dTon bay for Torpedoes. After all, you're 'flinging' 7.5 dTons per shot, in three 2.5 dTon blocks. Handling equipment for weapons like that taking up most of a decent-sized room is more or less believable.
A missile bay, by comparison, fires only 1 dTon's worth of ordnance, as you point out. I've no idea what the rest is for, either. If the 'missile launcher' was explicitely some sort of mass driver to impart an initial acceleration, fair enough, but then there would be/should be a difference between the turret missile racks and the missile bay tubes.
Reloading is very easy and straightforward, and if you could actually create an external environment that was the same every time, you could do auto reloads with no more than twice the actual footprint of the vehicle (assuming you don't need to worry about where you dispose of your empty pods). People are only required because of the many variables you have being out in the field.
But I would think that torpedoes would be handled like naval shells, since we are talking about magazines to store them in. You would certainly need some tonnage for the equipment to have the ready rounds. But not the tonnage that is set aside. Since missile's don't bend very well, your machinery is going to probably store them horizontally on a track-like mechanism. The torps would be fed from the magazine to the launcher, and then loaded. Assuming you had an external turret "bay" the only time you might need to alter their plane would be to load them (though missiles all have bearing, so you should be able to launch vertically and let the torp's gyro's re-orient it towards the target.
Turret's store a single round onmount. Nothing in the description of missile or torpedo bay's says anything about onmount ammunition storage. The torps would be handled in the same way the missiles are. In some ways though, the missile possibly would require more tonnage, as you have to have 12 feed mechanisms to the three of the torpedo. And while the torpedo is physically larger, you can turn off gravity in the turret area so you only have to worry about mass - which the machinery should be able to easily handle without being overly large.
So, in summary, machinery the size of a room (and lets be generous and give 10Dtons (that's a pretty good room) is MORE than sufficient to handle weapons of that type. So the question still remains... what's the rest of the space used for? Since it's not ammo, those are some pretty generous maintenance access points!
