Valid points as far as they go. Remember between Spindle and 2nd Manticore 56 BCs and 12 CAs were captured. They could be reclaimed relatively easily. As to where, if I remember correctly pre-Icarius Basilisk was said to have reclamation slips and has has 9 years to be rebuilt.
Again, it is still months of work. Months of time where instead of working to keep their own ships operational, they are working on useless junk.
Again, valid as far as they go. Since the Frontier Fleet detachment has DDs and CLs, that's what they would want.
That misses the point. Rozsak rejected taking in the State Sec ships captured at the Battle of Torch because he did not want to have any untoward recognition or publicity of having those in his service. Rozsak has thus far managed to disguise his naval expansion as a very small training and support mission to Erewhon. His spacers are ones hidden in plain sight by having them officially "loaned" to Erewhon. Taking on manpower expensive vessels would shred that disguise completely, which is why he did not want the PNE ships, and is also why he does not want any SLN ships.
Spindle and 2nd Manticore scores were 48 DDs and 53 CLs. Tweak the emission signatures and use false transponder codes would hide true ID quite a bit. As to to training, two points. Solly crews, Solly ships. And how M class star systems are there within 20 light years of Smoking Frog? "On the way" also has several problems. What happens if a SLN task force shows up at Erewhon? Deliveries STOP. What happens if Battle/Frontier Fleet comes calling before the new Maya Navy is up and running? Of course new and improved is better than junk, but junk is here now.
The
origin of the ships is irrelevant. What is relevant is that Rozsak cannot disguise such a massive naval expansion. Taking on those ships would require tens of thousands of personnel he simply does not have.
As for what the SLN does or does not do before the ships are ready, I point you to Cauldron of Ghosts. Rozsak (and Erewhon) already has a force which can stop any likely intervention from the SLN. Any
unlikely worst case scenario has him calling for backup from the Alliance. It also helps that the Maya sector is still playing at being the nice, loyal OFS protectorate it has always been, so they are not likely to get an unfriendly visit from a Battle Fleet task force any time soon.
