Sorry, Didn't mean to sound snippy. I can be a bit touchy when I hear or wonder if I'm getting another variation of, "well, that's not what we saw in ENT..."
Yeah, my basic idea is that this design is about mid to latter 22nd century. Then again I'm also quite taken with some of Masao's
designs for mid 22nd ships. They're definitely more primitive than TOS and they have their own logic in that you would need something relatively uncomplicated to construct in large numbers if you're trying to build up a battle force quickly for a large scale armed conflict.
Of course, no reason why both concepts can't co-exist.
