At the least the AOPS deserves a Smart S radar and MASS for some self defense.
I'm not picking on you, as others point out this sort of thing, but this is a good comment to follow down the rabbit hole.
Smart S would require:
-5 more crew to operate the system,
-2 maintainers
-changes to the AOPS electrical load (does it have spare capacity or do we have to do load shedding of other systems to make this work).
-A space to put the Smart S cabinets with their cooling (changes to the cooling system and chilled water system, there is no spare capacity on AOPS for this).
-Mast redesign to place it in an appropriate spot that could resist the ice that will build up in the arctic.
-Identify Friend or Foe interigator cabinet, associated cooling and power (as thats a seperate cabinet to the SMART S processing one)
MASS would require:
-MASS ammo magazine
-minimum 4 launchers at appropriate spaces around the ship, perhaps 6 for a ship of that size...
-again more electrical load on the ships plant
-a passive electronic warfare sensor to identify whatever missile is coming at the ship, with its own antenna and cabinet, and cooling (otherwise MASS is just a party machine with expensive confetti and fireworks. MASS only works if you ID the missile and use the appropriate defensive timing and patterns to avoid being hit)
-5ish people to crew the EW sensor and EW supervisor positions over all the watch rotations
- 1 maintainer
Both those systems would be useless without a Combat Management System to integrate them together which would require:
-at least two cabinets with associated power and cooling in different space than the radar, IFF one and a different space than the EW cabinets (for security purposes)
-4-5 consoles in the now SINGLE purpose ops room (when from multi purpose reconfigurable to non-configurable)
- no increase in crew as the Radar Techs are also able to work on
the CMS.
So we have added 5 cabinets, 3 chilled water systems (probably need about 50 tons of chilled water to do that), 12 crew, new spaces for this equipment, taken over a multi use space, 4ish consoles, a mast redesign, two new antenna, and a magazine space.
For almost no survivability imprvements.
