It's a powerful ship for its size, but is it good value for money considering what Maya's neighbours are fielding?

It's a powerful ship for its size, but is it good value for money considering what Maya's neighbours are fielding?

For 1923 => yes
The Mayan considers battleships as artillery platforms.

Increasing speed costs too much in BP to the detriment of guns.
Thus, the Mayan battleships have a uniform speed of 21kts and form a block that can stand up to the Aztec BB.
Thus, during the battle of Vera Cruz, the Aztec did not remain facing the artillery of the Mayan line.

1928 BB, 21kts, will be more powerful but still limited to 175m.

=> Don't forget, Aztecs had 3BP when Mayan 1BP only.

Mayan 21kts battlelines (Pacific & Atlantic) in 1928:
24x254 + 56x280 + 54x356

Next batch of Mayan BB laid down in 1928 w'll be 4T3x356 or 3T3x406 (175m & 21kts)

[Jefgte]

Hmm... Test
1923-4T3x356 is 22800t
1928-3T3x406 is 22500t

Actual PLAN from 1923 to 1934
12 x MTBA-40t
20 x DD 1000t
6 x pocket cruiser 6700t
6 x escort carrier 8900t
2 x 19700t BB
2 x 21000t BB

Does make sense.  The Mayans really have two threats, sort of 4, that they have to defend against.  Primarily the Aztecs, with a strong number 2 of Vilnius.  And then the Parthians and Romans due to proximity though neither is super likely to be a primary threat rather than an allied threat in a conflict.  They can also provide air cover for most of their force so long as it stays within range of home waters, so fleet carriers aren't a concern.....and they're hopelessly behind in aviation anyway, so they can't simply try to match even the Sultanate in carrier aviation.
