It certainly shows the direction that the N-verse is heading so far as battleship development.

The super-battleship- massive, impossibly heavily armored, and armed beyond comprehension- which never managed to catch on in our reality is destined to rule in the N-verse.
So 'ere's to you, Fuzzy-Wuzzy, at your 'ome in old Baghdad;
You're a pore benighted 'eathen but a first-class fightin' man;
We gives you your certificate, an' if you want it signed
We'll come an' 'ave a romp with you whenever you're inclined.

71 BP and 80 months (minimum) to build it. That's 13.33 halves, or in reality, 7 years, at 5.714 BP per half. That's a big ship. If you figure the typical medium-large nation can add a full BP every 4 years between 1920 and 1930, then every 3 years after that, it'll be hard to maintain heavy building capacity to build ships like this in any numbers.

So it'll be interesting.

Definitely true, but if one is willing to pay the extra $$ you can have it in 4.5yrs.
71BP=71mo + 9mo=80mo
Pay 1.5x cost and get 2/3 the build time or: 80mo*.66= 52.8mo=4.4yrs. Of course that's at 7.88BP/HY and last HY of 7.89BP.
