The Tuwalu block Is do this individually, if they fill both module slots

with Standard or Gunpack modules. The others are a bit more arguable
- they don't really have any more firepower per mass of ship than the 
published FB1 ships. What they do have in spades is survivability, but 
that's something else.

Um, Alan? The only way you'll ever get the BORON designs 10% cheaper per

Mass than the FB1 ships is by installing Cargo or Survey modules (not 
Secure Cargo, mind you - they're too expensive!) in every module slot on

the Numbats and Tuvalu block Is, and none at all in the other ships. And
you do *that*, "slightly inferior firepower" is an extreme
even for someone brought up in Britain :-/ (...why am I reminded of NZ 
defence policies while writing this...?)

1-3% cheaper per MASS is more accurate for combat-equipped BORON ships, 
though of course it depends on exactly which FB1 ship you're comparing
You can push it as high as 6.6% by choosing the "norm" ship carefully...

OTOH the NAC Vandenburg costs less per Mass than any fully armed BORON
ship :-/

Um, Alan? I've meant to ask you this for over a year, but... which FB1 
ships are you looking at when you call the BORON firing arcs "unusually

A Tuvalu armed with Standard modules does have wider firing arcs than
FB1 pure-beam FB1 CHs, but its distributions of beams over the various
is pretty similar to eg. NSL and NAC BCs (and heavier). If the Tuvalus
Gunpack modules instead - and that's what you describe as standard -
beam distribution closely matches those of many FB1 CLs and lighter.

A Numbat/Gunpack has exactly the same beam armament as an NSL Radetzky 
(which is IMO forward-heavy). The Numbat still has an edge over the Rad
dogfights, but that edge is due to its more powerful engines - not to
beam layout. A Numbat/Standard is similar to an ESU Beijing/B.

A River/Standard has 1 B1-6 more than the standard FB1 DD armament,
its broadside firepower to 71% of the frontal firepower vs 67% for the 
stock DDs, but the ESU Volga beat them all by adding a B*2*-6 to the
DD armament. A River/Gunpack has exactly the same beam armament as the
Krprz Wilhelm and NAC Huron CLs (though the Huron is more maneuverable
the River).

A Snake has exactly the same beam armament as the (slightly cheaper and 
less protected) ESU Novgorod class, and the NAC Tacoma has a
heavier and wider-arced armament (outgunning the Snake by 2 to 1 in the
and AS arcs, by 3 to 2 in a head-on pass, and equals it elsewhere). The 
Snake's thrust-7 engines don't give any significant maneuverability 
advantage in dogfights compared to the thrust-6 engines of the Novgorod
Tacoma - they're all restricted to 3-pt turns.

This is exactly the same problem as Phalons with all Pulsers tuned to
suffer, too <g>

Why don't they just build anti-KV beam modules, with 2xB2-6 + 2xB1-6 (or

1xB1-6 + 1xPDS)? That'd make the Rivers and Tuvalus quite respectable 
anti-KV units too... and it'd be a LOT faster than refitting the 
non-modular parts of the hulls.

Finally, should the Waikato cost 312? I get the NPV to 314 (ie. 322,
less 8 
for the not-installed structure of the module).
