Choosing an unbuilt warship with maintenance provided

Which real paper warship design would the panel choose to own if it appeared fully functional?

The preferences include F3, a Vulcan-type workshop ship, Design Z Minotaur, K2 and a modern Type 83, with maintenance waived by the premise.

The audience's Number 13 choice sets up a comparison of practical utility and favourite designs. A floating machine shop appeals for its repair and manufacturing capacity, while F3 receives more than one endorsement. M2 is suggested partly for the provocative appearance of its turret arrangement. More serious cruiser and capital-ship choices include the late-1940s Design Z Minotaur and a twelve-16-inch-gun Conqueror variant. The fantasy of unlimited support matters, because without it the ownership question would be dominated by upkeep.
