I like Heinlein 2 (that's what I'm callin' her) but she has a prepubescent look to her, like she's yet to blossom into full ship-hood.

A completely off-topic comment...
The 'hero' ship Rocinante, from The Expanse, gets all the press, but the little Xinglong is the that one that catches my eye...got the look of Space Cowboy's Hauler from Battle Beyond The Stars...along with vertical SSTOs, I got a weakness for space opera, bad movies, and blue collar spacers.
