To finish my story, the enemy still had one gunship wich tore trough my terraformers, thats 20 terraformer dead, after their attack they slowly moved toward, well slowly.... they did move at 12km/s but since they were on the outskirt of the solar systm it still took them a couple of days, i cranked up my missile production hoping my little PDC would get more luck going trough their damn PDS....
Anyway they finaly get in range of earth and i started spewing all my missiles, i had 2000 size 6 missile stockpiled and all of them had active sensor should something happen to my PDC. So i fire away non stop and they get into knife range and start hitting my PDC every 5 seconds, good thing i had massive armor on it. First voley hit the enemy, all of them strike and hit! No PDS engaged my missiles wich i dont understand, so seeing that i fire everything i have even my AMM thats still 10 more damage. That 50kton ship sure has a lot of armor. I finaly blew the last one of them using my missiles, used about 200 of them but victory!!! My PDC did suffer some scorching hits tho as i had only a couple launcher left after a magazine explosion. *After the fight i waited 30 days and used SM to repair the PDC since its kinda wacky to repair PDC, at least it was in the past*. Seeing the success the PDC had fighting of the enemy, i quickly designed a missile base wich had well, only missiles and in greater number. I dont mind overshooting an ennemy with my anti-ship missile since they can just switch target if one blows up, didnt know how effective it would be seeing it was my first attempt at using missiles with sensors on them.
I realised 2 mistake i did in this fight, one major error was going in point blank range with my ship, my ship had supperior range than their weapons but instead of falling back to earth and let them slowly catch me i went straight in and they closed to gap and since they were only about 200m/s faster than me i had no chance to escape them. If i had stopped my ship and turned tail as they enter my max range i could had let of a couple dozen hits before being in treatening range of their energy weapon and would had taken them a really long time to get in ramming range. First lesson learned.
Also it appears that if i had launched my missiles as they were very close they would had gotten trough wich i didnt even launched any missiles with my ship seeing the first long range voley got obliterated. Lesson learned, when in close combat shoot missiles even if you are not sure if they will hit, at best you will overload their fire control and some might get trough by shear luck.
I designed a fast movers with 50 box launcher should more come, currently retooling my shipyard to mass produce them, they weight 12 ton and have no jumping capability by themself but they are supposed to be last ditch defenses and still provide military defense points these colonies often request after a certain size, so i can just build done or more hanguar PDC and stick these ship in so they dont use maintenance.
About 2 month later more hostile transit poped out, this time they were about 15kton so not that bad, but there was 4 of them, good news this time i had no ship between them and me, because well... i didnt have any left. More good news... i still only have that single PDC and this time they will come with their missiles! Being on the ground the PDC didnt have to fear about running out of amm since i had like 5k of them sitting on the planet and have 10 CIWS each shooting 10 time at 20km/s tracking shoudl any straggler go trough the AMM barage.
They appeared to be splitting up just befero reaching earth and i zoomed out to see what was going out, they were in range of my missiles as they started spltting and 2 of them was going for the civilian ships trying to flee behind me, anyway, new thermal contact, 2 salvo of 7 size 6 missiles going straight toward the civilian, i quickly engage these missiles with my aam, they go 50km/s mine goes 75km/s so yeah my missiles shouldnt have too much trouble catching them even tho the enemy missiles have a pretty far closest-point-to-earth. by the time i send 2 voley for each salve thats 20 seconds, mutilple other salvos are detected closing on me and the civilian, during that time my anti-ship missiles are already flying, launching 5 salvos of 10 missiles toward each ship contact. My missiles had a 50% interception rate ratio afainst their missiles so not that bad, i did manage to take out all missiles going toward the civilian and myself, only letting single missiles go toward me should i miss a couple in a defense fire.
The enemy missiles was no match against my crazy CIWS, im confident i could had easily let them all hit without missiles interception and still not receive any damage. After a couple of planet reload since my magazine went empty a couple of time they all fell down to my missiles and they didnt had the chance to close on me to get into knife fight.
Now will i have enough time to properly mount a defense fleet and send the fight back to them? No idea. Also they are all coming from the Toronto system and funny thing is i have 2 Geosurvey ship there and one grav survey, none of them had any contact with them even tho they had been in the toronto system for almost 6 month!, thats 3 ship rolling about the system and still operational..... They really want my capital.... Now to try and mount a proper defense fleet or harrassing fleet with these box launcher. My 12kton ship goes 15km/s but burn fuel like a supernovae..... Hell we will see how it goes and hope it was the last of them! For a while that is.... Still need to salvage everything thats gonna take forever... and rebuild my terraforming fleet, man thats 20 of them and some of the commander was crazy good but sadly they all died so my terraforming bonus commander might not be as good.... Eh oh well.
