Battleship design
« on: November 24, 2021, 10:38:02 PM »
I am putting together my first large (60kton) battleship and would appreciate input/feedback from the hive mind.

My concept for this ship is that it will operate as the flagship of a fleet (although in some cases there may be more than one in a large fleet). It provides both a moderate amount of PD as well as decent DPS. The lasers are quad-turreted with 2x racial tracking rate in case I run into someone using beam fighters or FACs, as currently I do not have a good counter to that (I am not using missiles). For that reason I included extra BFCs. I included a small hanger (250 tons) to carry small (30 ton) sensor scouts, as well as 250 tons of troop bunks for a small contingent of anti-boarding marines (mostly for RP purposes).

The maintenance life isn't quite what I'd like it to be, since it's about the same as the deployment time, but I have included a Main Engineering bridge so I expect to get some reduction in failure rate from having a Chief Engineering officer, in addition to what 50% of the Engineering rating of the senior officer. All officers will of course be hand-picked.

I have some minor redundancy in BFC and ECM, but I used a single power-plant to power all of the lasers. Some redundancy there would theoretically be good, but I'm on the fence since the efficiency of having a single large reactor (no boost, btw) is pretty nice. I suppose I could use some boost, since the explosion risk will be reduced by the Engineering rating of the Chief Engineer, but I'm still pretty leery of losing a battleship to a reactor going critical from an unlucky hit generating shock damage.

A couple thoughts:

- Subdividing your fuel storage (use standard Fuel Storages instead of larger ones) is an easy, if somewhat costly, way to get more internal durability.

- Damage falloff on lasers is a bitch - if you look at the outer half of any laser's range, its damage is 1.  Really big lasers can get around this by having the "outer half" be "outside of the 1.5mkm maximum range", but otherwise you're doing pinpricks until you can close.  If you want to fight at range, would a set of particle beams be better than the turreted lasers?  Maybe a mixed armament, if you want to retain some anti-fighter capability?

I agree with the above RE: lasers. In my view, the solution here is that lasers are still fine, but for a large capital ship you really want to be using the biggest lasers your money can buy. You have IntCF engine tech which is 40k RP if I am not mistaken, surely you can afford to research up to 30cm lasers and the wavelength tech of the same level. This will give you much better range, likely well in excess of your BFC tech at this level. Given the large size of these lasers you might consider twin or triple turrets instead of quad just to retain the ability to divide your fire.

Otherwise the design looks reasonable, I am particularly enamored with the proper use of very strong shields which make up for the admittedly mediocre armor belt. There might be some room to push up to the 60k ton limit to mount some extra engineering spaces or a redundant reactor configuration to assuage your fears.

It's a nice well rounded design, I just have RP preferences for battleships. I like to think of them in a classical naval style where the are large, heavy, wrapped in armour and carry BFGs for insane levels of first fire damage.

In m current game my battle fleets have 3 of the following design, each acts as a command ship of a sqn within the fleet. You can easily design ships orders of magnitude more efficient than this and far far cheaper. But for total damage output these are monsterous.

For better or worse, I am not planning to "fight at range", and I am primarily concerned about anti FAC/fighter (beam or boarding) capability since that's a gap in my fleet's capability.

My typical conops is to be 25% or more faster than the enemy fleet so I can close range reasonably quickly. I have lots of smaller ships with 45cm spinal lasers (53 damage per hit if you get in to 60km range will ruin your day) to punch big holes, and want this battleship to both soak a lot of fire (if the enemy chooses to cooperate) and/or put reasonably rapid fire smaller shots into the big holes punched by the destroyers.

I considered using railguns, since they have better DPS. I ended up choosing turreted lasers because that allows me to get high tracking speed, which isn't important for the primary purpose of poking at open wounds, but does help if I run into FACs or fighters. I do have 30cm lasers and soft xray tech, but chose to use somethign that fires faster, again in case I am facing FAC or fighters (and particularly boarders) and want to get more than one shot at them before they close the range. My BFC is 384,000km right now, so for a target goign 20km/s I only get one shot in with the 30cm lasers, and damage will depend on where in the time-tick they cross my BFC max range. With 20cm lasers I always get at least two shots in before they close, meaning one shot is guaranteed to be higher damage and much higher likelihood of hitting.

I have not optimized the engines/armor yet... I'm trying to get itup to 60kton to take advantage of shipyard size but I also want to keep it the same speed as the rest of my current fleet (~8400 km/s).

Note that I'm not discounting your advice, just trying to explain more of the context I'll be using them in and what I'm trying to accomplish, so you can better judge the design's suitability for said purpose.

This is in no way meant as an insult, but i looks like you did the exact opposite of the pre-WW1 navies. They build battle Cruisers to be cruiser hulls with battleship weapons. You here have a battleship hull with cruiser weapons (and mission profile).

That said i do not have any tweaks for your design, my personals preference would be to put a spinal on it and min 30cm lasers, then have the 20cms and the anti-FAC roll given to cruisers and DDs.
