Ragnarock Class Dreadnought
If you're trying for the Norse apocalypse it's Ragnarok. Nice name, though.
Wedged shaped hull streamlined (Can make planetary landings.)
And can also put the maximum of 80% of its bays into a single barrage, which is good.
16 armor + 3 reflec (Rad and Psi shielded)
As tough as it can get - at least until it takes a few armour hits. Weren't you thinking of armoured bulkheads at one point?
Jump 3-4 (6 if I use the Darrian rule)
M-Drive 6
PP 6 (x2)
2x Meson D spinal mounts rapid fire TL16 [12320 tons - 125 hp's]
3000 large meson bays
2000 large particle bays
10 launch tubes for drones (20t missles) (might delete these)
2000 triple beam lasers
2000 particle turrets
Meets all limitation rules. Was going to say that triple beam lasers for point defense don't help (since any hit on a missile is death) but then remembered that against barrages they do; barrage defence just works off the number of lasers, regardless of how they're mounted. Might recommend some TL upgrades to the bays, by the way - at TL16 you could stack Resiliant and High Yield, or High Yield and Accurate, or whatever.
6 x 2 meson screens
6 x 2 nuclear dampers
4 x 2 black globe generators
Fair enough.
One thing I will tell you is that at the moment the ship can neither move nore fight. Unglamourous though it may be, one or more Core/9 computers are the
real heart of the ship. More than anything else, that lets you run up to 4 Fire Control/5 programmes simultaneously, which will help figure out how you want to set up barrages and gunners; the lasers don't need it as they'll only be firing defensively against barrage fire. The spinal mounts demand a Fire Control/5 each because if you're going to miss with those things then you might as well go home.
Some remote operations software might be useful, too - you could consider a halo of escort drones rather than needing to put turrets on the ship if you prefer that option. Also, sufficient computer power lets you run stuff like Expert Tactics (Naval)/3
Equally, no matter how awesome the ship is, it is not invulnerable. A spinal-mount meson cannon (admittedly a small one) can pack into 2000 dTons and is available at TL14, which is standard issue for the Imperial Navy and it's peer organisations, and against such a weapon the sum total of your protection is your screens (which admittedly aren't bad). Equally, barrage-fired, High Yield capital weapons with decent fire control can take armour 16 and beat it.
As a result, the ship will take damage and it pays to be prepared. Armoured bulkheads on important stuff and a decent stock of repair drones are a good start.
Why not?
Also, I mean a knife drone from Ian M. Banks... I.e. the sort that is a mass produced incredibly powerful weapon that laughs at your power armour.... and the drone that launched it probably laughs at your ship. It wasn't a serious suggestion, but it would work
Arc-Field technology from Central Supply Catalogue would work if you want a Culture Knife Missile. Kind of off topic, but there you go.
