I put a lot of time into posting a BO carrier type of ship... but eventually scratch the idea because I couldn't balance it.

IMO, a black ops carrier has a lot of potential, this was the highlights of my idea:

1.) It should be closer to a t2 Orca/rorqual than a carrier.
-- Main idea: A support ship able to safely navigate through hostile territory, capable of supporting and supplying a small group of nomadic explorers.

I wanted to give it:
a.) Allow it to use normal gates.
b.) Allow it to use a covert Jump Drive... meaning it can jump to either covert or regular cynos (as current BO BS's can).
c.) Allow it to fit a clone bay.
d.) Give it a Ship Maintenence Bay that allows refitting in space, and has a capacity around 600-850k m3
e.) Give it a SMALL corp hangar?? (1k m3)
f.) Give it a large cargo hold (100k m3)
g.) Give it a large fuel bay....
e.) ?? The BO cloaked velocity bonus ??

This is a significant "want" list, and as such the ship needs some SERIOUS drawbacks.

1.) Why the small corp hangar?? To encourage the use of the cargo hold for stuffs. This isn't a ship to smuggle crap through empire... If you lose it, most of the loot you have should be available to drop for the enemy. Hence, it will primarily be in your cargo hold.

2.) It would have very poor defenses.... As in... no drones, no weapon mounts, Very limited midslots (two?), but perhaps several lowslots to allow hull tanking (four-five?). It would have a base HP stats about 150% of the Orca. This is a ship that should primarily survive by staying cloaked 90% of the time... HELL NO, IT SHOULD NOT HAVE A COVERT CLOAK... Why so many lows?? So morons can put on cargo expanders and make really tasty ganker treats, and paranoid players can put a dcu and a bunch of bulkheads to have an EHP greater than a JF.

3.) The ability to use both Jump Drives and Gates in a Carrier is extremely valuable. As such, it needs some extreme restrictions on this.
a.) It would have the same Jump Range as a BO BS.
b.) It would require fuel consumption on par with the BO BS's, but would ideally have a large enough fuel bay to travel deep into enemy territory and return.
c.) It would not have its jump drive always active. In order to use the jump drive, it would need to have a jump-drive-bay (similar to clone bay) installed in a high. Before being Jump Capable, the Covert Carrier needs to activate the Covert-Jump-Drive-Bay. I'll explain the mechanic I imagine for this below, but understand, for this ship, the Jump drive is not a get-away-quickly tool. You will NOT be able to insta-jump.
-- What this essentially means, is that gate travel is its most common method of travel. The Jump Drive exists to maneuver through hostile territory, or for the extremely timid.

Why the clone bay? So you can feel comfortable sending a scout through a gate. If he dies, and gets podded, he can JC back to your ship.

How will the Covert-Jump-Drive-Bay Work? You activate it, it prevents your ship from moving or cloaking for 3-5 minutes, and it consumes 90% of your ships capacitor. To jump, you need to regen its capacitor up to 70-90% (Depeding on Character Skills). Give it the capacitor of an archon (80k), and maybe even a cap regen penalty while the Jump-Drive-Bay is activated. Why? With a large enough base capacitor, cap boosters and non-capital remote energy transfers will typically be worthless for replenishing cap. Tweak its stats so the cap regen time from 10% to 70% cap is ~1 minute (when fit specifically to regen cap) to ~4 minutes (using only its base regen rate).

I have no idea if this is what you have in mind... but this is what I've thought would be a neat addition to the game. I'm not sure its balanced though, as a gate traveling BO portalling carrier is just insanely potent.

I'm in a black ops mood today, this would be interesting to see. Only complaint i have about it is it is like a "mini titan" and titans are getting **** on at the moment would'nt want to steal their thunder completely.
