The engines are 10HS for the 240EP Stealth Drives. The Stealth part of that name means their thermal signature is reduced to 16% normal, my tech is pretty high.
After some consideration, and careful reading of some good advice in this thread, I decided to scrap the jumpdrives from the designs, say screw it to the engineering spaces on the frigates, and gave them a second 240 EP drive. And made a carrier after all. A cloaked 45000 ton carrier (85% signature reduction). The darn cloaking device is 90HS. I designed an eco (0.75% power) stealth (16% thermal signal) 1200 EP drive just for the carrier.

EDIT: and here's pew pew frigates (their 15cm laser is actually a spinal 12cm laser, I couldn't fit an advanced spinal or anything better really), a carrier that swapped out magazines for more fuel, because the beam frigates drink a lot. Also, a cloaked jump tender that can take itself, and 4 carriers through a gate, unless squad size 5 means that it can take itself, plus 5 carriers.
