How long do empty ships stay in space

The Poseidon method should still work, to my knowledge of the patch. I will confess I haven't attempted it. It is, however, my understanding that any ultra-deep-safe created by this method will be pushed into the acceptable boundaries on the next downtime so I wouldn't try stashing anything there.

Mid-warp bookmarking to create off-lane safes is a much safer and more reliable method. There's no such thing as an unprobable safe spot anymore.

Assault ships are a bit heavier and ment for "prolonged" fights. Have better tanking capability. Can deal a nice amount of damage as well as take in a nice amount of damage.

Interceptors are very light, very fast version of the tech 1 counterpart. Have very low tanking capability but rely heavily on speed as a "tank". Can deal a very nice amount of damage.

In proper hands these ships can be very dangerous. I think they were created to enhance wolf pack tactics.

You need to be aware that in some cases a more skilled pilot in a cruiser will be in your way. You have a great chance of dying.
