I thought there were +HP modules in ToA?
There are ship +hp modules, but no starbase hp-assist modules.
But they're not worth the space if you're trying to rack up military points. On a huge hull, you're looking at 2 hp per space, which equates to 0.5 weapons per space, before multiplied by hp modifiers and the omega defense system.
A BHE/nightmare torpedo, on the other hand, is ~1.78 attack per space.
Huge hull, 115% miniaturization (322 space): 1 BHE/nightmare torpedo, 77 organic hull platings or integrity grids.
616+90=706 HP*2.05=1447*2(Omega Defense System)=2894/4=723 military might "weapons", plus 25*1.25 (orbit bonus, actually 1.26)=723+31=754.
(60% standard bonus counting Xinathium Hull Plating, 70% if you get hull strengthening from the Drengin tree, 85% if you get organic hulls from the Iconian tree, +30% bonus from customization points)
322 space = 23 BHEs = 575*1.25 (orbiting bonus) = 718 (actually it's 575*1.26=724) + 90*1.6 = 144 HP /4 =36 "weapons" military might. 724+36=760
So a huge hull full of BHEs, in orbit, with no military bonuses whatsoever, contributes more to your military rating than a huge hull with 1 BHE and filled out with 77 HP modules, even when all HP increasing sources are used, after being multiplied by the omega defense system.
You might also notice that I haven't used an attack/defense boosting module for this example. That would tip the balance even more so in favor of weapons-or defenses, for that matter.
The all-BHE ship is also 1100BC cheaper (5100BC to 4000BC).
