      From: adam.w.krajewski@gmail.com              I don't know yet how heavy the enemy's armor be, I need to think about it, but       only resupply that ship can get is on the tugship, and in case of long,       planned operation, there will come new tugs with supplies. So, the tug is       orbiting the star at safe        distance, while ship fights other ships near the habitable planets, and can       perform bombings on them. Hm, how long and how much fight will be on missions       is hard to think about now for me, maybe it's better to wait with that to       moment when the design is        more complete, or make ammo bays and other equipment, propellant tanks       interchangeable and modular?        Having a lot of shrapnel and few slugs seems like a good idea, and can also       lead to some interesting plots I think, like the ship running out of       penetrators and having a problem dealing serious damage to internal parts of       ships.        The crew is in suits, but a round hitting their storm cellars and changing       into plasma and fragments would probably kill them, although there can be so       many of these cellars, or even none, that it becomes hard to do anything to       them. Hm, I see your point        now.        The idea for kinetic missiles came to me from real life hypervelocity anti       tank missiles, but seems I have to rethink it, I am not sure if it could work       in my original version, with oversized fusion rocket and high acceleration.       With the nukes comes the        problem of guidance, if the ship can be hit with nuke, that won't do super-big       damage, it can be hit by kinetic missile. The Casaba Howitzers are other thing       though.       The EMP seems good, but same thing can be done by PBW, right? I am not sure if       that would work only for charged beams or not, in the former the range would       be limited. How fast do charged beams dissiapate in vacuum?       If the artificial gravity is limited in use because of "something", I don't       think it would change everything. Your idea for limiting it sound good, lets       call the material gravianium :p It can be a next McGufinnite in the setting.       Found only on a few        worlds, hard to master, only for rich.        The fixed positions would also mean engaging multiple targets would be       hardcore and cause the crew vomit, and also destroying manevuering thruster       would render coilguns unusable. Maybe it's better to go with smaller       projectiles, more hits needed to kill,        but you can compensate it by targeting a few turrets on one target. Or, have       one fixed, forward facing big coilgun, and the rest in turrets.        Gonna calculate the recoil strenght.       Ship is expected to hold 2 gees for a few week to 2 months or so, something       that could give it small percentage of c, like 0.05 or something.        So, instead of bad looking radiators, a nice system that makes a hisss sound       when used? I am buying that!        But still I will include some radiators, I need to dig through Atomic Rockets       and find one suitable for warship.        Ardans are not merciful folks, they will punch you with nukes as long as it       takes for you to understand who is a ruler B)       So, gotta do the ship math. Arrhh, estimating the structural mass and trying       to put propellant so that it doesn't make ship look bulky and not fun...       This gives me thought, why not use carbon or xenon or anything heavier for       propellant? What are the pros and cons of such way?              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
