We don't have enough space for the current fleet plan, especially if they actually replace the MCDVs with bigger corvettes. Jetty services are already lacking for the current fleet, and the FMF isn't big enough for the maintenance load either. Stacking ships outboard of each other is pretty shit, and each class we are talking about are all bigger than what is being replaced by a lot.
Not thinking about infrastructure, training, crewing, 2nd/3rd line support etc during fleet recapitalization is shortsighted, to be kind about it. We already do 'fleet jenga' to try and accomodate SWP requirements, that would be brutal. I hate TBS, but forcing us to include sparing, infra, training, IP and similar considerations in major capitol project costings at least ensures it doesn't get cut and pushed to an 'in service' problem from the get go. We still miss a lot of that, but better than some NP projects, where the delivery budget gets slashed to the point where your tech pub is a glossy flier, you sparing plan is 'future problem' and training is 'OJT' supplemented by youtube videos (that you can't access on the DWAN).
