Suggested improvements- turrets to rail system, rail docker, but int he meantime the blueprint should have them set to turret and missile, and active, not ship and inactive.
I would like to see all modules linked to the primary jump drive and only 1 module to the backup drive, you only use one jump drive on a regular basis anyhow, so why not make the primary faster?
like Gristle said- exiting the core puts you on the top, even if you remove all of the blocks above the core. and Medical supplies and radar jammer would be amazing. The power on the ship allows it to permajam, and you can charge the jump drive entirely before it runs out of stored power.
