So I created my first war ship.
Comments are welcome (aka: what is wrong with it?:P)
See later post

Ok there appears to be a few things i would be doing quite differently.
1: it can't go very far. 2 months. i usually deck my ships out to handle about 1.5 years. needs moar fuels.
2: Its going to explode. See the annual failure rate? stuff goes wrong every year, and if a few of your big ticket items break down, the whole ship could start to crumble and explode. Add some engineering spaces to get that est time up to, oh, 2 years should be more than plenty for ion ships.
3: i don't see a reactor-- theres no power for the guns to shoot anything, unless im blind and sleepy.
4: 1 shield unit is not going to help-- I usually do five for a small ship like this.
For a beam ship, the speed is good-- you want more engines on a beam ship to help close gaps while they shoot missiles at you.
My first ships that i designed like this were not very successful. i'd take the active sensors off and run a dedicated sensor ship-- great big arrays to give some serious range-- 60 m km is not very far at 4km/s.
I make a sensor ship of about 6600 tons that is a huge missle sensor and a huge ship scanner, and put some passives on there. Deck it out with armor and shields because those active sensors make it a target. Then, your PD\Beam ships can defend it with incoming missiles.

thx, I'll post an improved version + the sensor ship when I have them finished.
I actually had no idea how much armour or shield I needed and the reactor was indeed forgotten >. <

Are they okay?
-
toss another 15 cm gun on there to use up all the power and consider that the scout ship is faster than the battleship
-
Shouldn't they have the same speed? They are useless without the other right?
I don't need another beam fire control if I add another laser right?

You may want the sensor ship to stay back and spot for you while the combat ships close. In this case having a little extra speed can come in handy to deal with any suprises that show up. You can assign any number of weapons to a single fire control. You might actually want to switch the 12cm for 10cm lasers if this is primarly for point defense and use the saved space for an extra 15cm. Depending on where your fractional points are you may be able to squeeze two on board and the power for them without slowing down much.

I updated my second post,
I added the laser and boosted speed to 5000km/s (+engineering space and fuel storage)
The squad turret is indeed designed for point defense but I think it should do fine as attack weapon versus crafts without missiles. I just took the fastest laser possible which was the 12cm.

After looking a little more closely I realized that both the 12 and 15cm lasers have the same range. In that case you might want to look at replacing the 15's with 2 tripple 12's and get the benifit of more lasers for point defense, and faster firing lasers for offense. The two points of damage is not enough difference when compared to doubling the cycle time between shots.

Ok, I think I remove the beam fire control with the lower TS, remove the 12cm lasers and make a total of 3 quad 12cm lasers.
I just need to design the power plants so won't have that much power left.
EDIT: Modified the my 2nd post. Is this good? I guess so, but I don't really know if they amount of shields/armor is okay.

You have a working design. The next step is to actually use it in combat and see how it works. When you see a potentially hostile contact make sure you exit out of aurora entirely and make a copy of the database. This way if you make mistakes in controlling the ships (ie forgot to set pd up when the missiles are coming in) you can go back and fix those types of mistakes. If you want a true learning experience, fight the battle out and see what happens. Then change the designs of your ships around and refight the battle to see how that makes a difference. As an example for a reworked design you could make the turrets tripple gun turrets and use the extra space saved to up your shields, armour, or both. Then see what works for you. If you do not have a decent missile ship for both offensive and defensive purposes then you will probably want the extra defenses. I would recommend 1 ship with 10 size 1 launchers and lots of magazines. This is your primary point defense and you want it to thin out the incomming salvo's so that the lasers can take care of the rest. You will also want at least a couple of long range anti-ship missile ships (60-100 mkm is a good start). If not then hopefully you are faster than the enemy ships which is problematical given your tech levels.

Ok, thx for the help.
I think I produce 1 sensor ship and 5 or more laser ships. I'll start on missile tech now (haven't touched that yet).
-
I wish i had explored a little more before coming here and getting ship design suggestions though-- you ought to take these beam ships out for a tour of duty and see how it goes!!!
-
Well, I actually started designing the ships when my colony on Titan was demanding protection, but later I realized they just needed a PDC. I didn't want to stop the designing though, so I basically have some ships now without a real purpose.
EDIT: my ships are EXPLODING at earth! They weren't doing anything! How do I stop this?

Did you give them any engineering spaces? Did you build maintenance facilities on Earth? This sounds like maintenance failure.
John
PS - That or they're caught in a Baen book :)
-
It are the ships I posted in this thread. They are both having maint problems every month and a sensor ship just exploded. . .
EDIT: I just added 50 engineering spaces (+more engines and life support) so they both have 50% failure rate. I hope that will make them explode less often.
-
Well, your larger ship is around 14.500 tons in size. This means, you need maintenance facilities on earth for ships of that size (73 if my math is right) to keep their maintenance clock from advancin.
What you have to keep in mind is this:
As the clock advances, the chance for maintenance failers increases. This means, your 50% chance becomes 100% chance after a while, then 200%, then 400 % (this takes quite some years, mind you) and after a long time, things will get so much out of control, that the ships start to explode.
You can think of this as your ships becoming 30 years old rust-buckets that simply start to fall apart.
To counter this, put the ships into overhaul every two or three years - for which you also need enough maintenance facilities.
As a rule of thumb, I calculate my fleet needs like this:
1/3 in overhaul
1/3 on the way to/from mission area
1/3 on a mission
Usually, this is a bit on the cautious side, leaving me with more ships ready than I realy need, but it´s better to err on the side of caution.
-
How many maintenance facilities do you need for X tons of ships?
-
i think its 200 tons per facility
-

200 tons per MF. However, the Summary section of the Pop window will tell you your maintenance capacity. I think it is called "Maintenance Facility Maximum Ship Size" and it is near the top of the right-hand column.

Ok, thanks.
So that is why my ship exploded. I'll make more MF before I make the new ships.
-
I would try not to push them too far over their Est Time before Overhauling them. Also when not in use keep them stationed over a maintenance facility to keep that clock from ticking - you'll need to ensure the facility has the required minerals for the duration tho, you can see what you will need in the Economics Window, Mining/Maintenance tab.
Building a fleet of Maintenance vessels that you can send to a forward staging area is always a good idea - (you will need to create a colony to base them at and ensure minerals are unloaded at the colony). Again, if you have several maintenance ships in orbit you can see the total capacity in the same place as if they were planetary structures and when over a colony they act exactly like planet built structures - just send your fleets there to overhaul.
-
Ok, thanks.
So that is why my ship exploded. I'll make more MF before I make the new ships.
And remove the 50 engineering spaces you put in (if you haven't already) - 2-3 years is good for estimated time to failure. It's ok to have an annual failure rate over 100% - that rate is proportional to how big the ship is (think how much more frequently something breaks on an aircraft carrier compared to a destroyer)
