1. I just have Nuclear Thermal Engines, although I'm working on the Pebble-bed reactors for the next level.
2. I am designing a mothership with active sensors.
3. The deployment time of 5 months was because I wanted it to be exactly 500 tons (for some reason), so I increased the deployment time to get there. I got some new tech and whatnot, and it got lowered down to 460.
4. I haven't for either.
EDIT:
