As can probably be inferred from the hull designation, the Chihuahua class will be intended to serve as a squadron leader for regular destroyers as well as the FAC tenders. I think I've over ranged the AMM's a bit, however reducing range to 1m Km only nets a single extra agility point at current tech levels, and well, that fleet defence missile warning radar was to juicy not to match the range. Magazine is worryingly shallow, but I'm trying to squeeze a lot of capability into a small platform. Possibly going to suffer the generalists curse, only managing to be poor at everything it tries to do.
Dropping the Jump drive on the Guderian however, has made the design look much more pleasant on paper, room for a 6th boat, expanded magazines to support the Missile boats, and improved range, all in a smaller package.
The PT-1 only saw a minor revision, trading out the Triple S1 engines for a single S3. A major revamp on the P-1 significantly alters its role, placing it firmly in the fleet defence interceptor camp I think. Interestingly, crew requirements left it with quad S1 engines, the S4 requiring almost twice the crew, for which there just isn't enough room.
So guys, Chihuahua jump tending and spotting for 3 Guderians, with a small 12 PT-1 strike package, leaving 6 P-1s flying CAP. Workable light strike solution alongside dedicated destroyer squadrons?
edit because I forgot to modify the flight crew quarters on the guderian for the FAC's new crew requirements.
Note : The 10m km AM fire control will only pickup size 6 and under missiles at 1m km apparently. Thoughts on trading down range on the AMM's to get the extra point of agility? Manouver 12 would cut maximum range to 1.8m Km
