Jump drives are very flexible and almost required. Jumps 30km a charge (unless jumping to a set waypoint that is closer). You can make an under-spec system with a computer and only one module on a capital ship it just takes quite a while to recharge. You can even have multiple jump drive systems on your ship charged at once so you could jump several times without pausing. On the other end of the spectrum you can over-spec the jump drive system with a high enough jump module to total blocks ratio and tons of power that will be able to re-charge the jump drive during the few seconds of the previous jump.
This plain, simple, un-armed and un-shielded jump sled I use to run to the shops or rescue stranded people. The small ice planet mining outpost in the background is my temporary base/ factory/ spacedock.
On the surface is the Mayfly, a multi-role stealth fighter. Perma-cloak/jam, jump, overdrive, scanner, high thrust-to mass ratio, twin machine cannons staggered centrally, a pulse missile, light shielding and two cargo/ drone docks. The pulse missile will take out one of the new up-armored Isanths in one shot and the machine cannon will do 2x2 damage per shot to a faction module so it is a very safe, versatile starting craft if you are patient. It looks ok compared to most stealth builds I think. Space wings!
This monstrosity started as the modest starter mining vessel, "Doug." The copy/ paste advanced build mode function is very useful. I was able to over time use it to 'stretch' Doug longer and much wider as I manufactured more salvage and power modules. You can even save copied templates. Salvage beams take significantly more power this release so after Doug hit the power generation 1mil e/sec soft cap it was outfitted temporarily with one then finally both 1mil e/sec externally-docked logic-controlled power generation reactors and enough power tanks to buffer the output. It's final form was re-named to, "Doug Deeper," which really seems like a porn name now.
Once I'm better funded and settled into a more permanent location It will be re-built into a more respectable appearance.
