So the whole dealy with the heavy industrial park... I'm also not sure if it's worth the price of 115p.
There are some non-obvious benefits to it: I find it likely that we'll get a heavy industry team out of it in a state of emergency, or some other misc benefits similar to the critical infrastructure duplication stuff (some narrative, some things that could influence logistics, etc.).
On the build times: With 9 (+2 under construction) Starfleet berths and 2 (+2 under construction) UESPA berths in the Sol system, that's a max of 11 (+4) berth-months saved per year. That's about the equivalent of a single new berth, which costs about 10-20pp in Sol.
Now, it does reduce build latency, which a new berth doesn't do. But then that raises the question of how exactly monthly build time savings work.
Builds and fleet distributions are currently scheduled and planned at quarterly granularity. Changing that into monthly is going to be
huge headache. If we compromise and say that planning still occurs at a quarterly granularity, and that months only matter during crises (or other times where monthly granularity makes a difference), then the benefits of single-month per quarter savings has starkly different benefits per ship class.
For example, assuming planning still occurs at quarterly granularity, all our current frigates take exactly 2 years to build and a 2 month saving would have no practical difference in conventional situations. Current 3 year cruisers and 4 year explorers would have a single quarter of build time savings.
We also don't know when exactly the monthly build savings kick in - is it at the start of each build year, or at the end? If it's the start, then that benefits repairs a lot. If not, then only 1+ year repairs can benefit.
Things are further thrown out of whack when you consider that the new ship design spreadsheet allows ship classes with monthly build granularity. So assuming the monthly build saving occurs at the end of each build year, a heavy industrial park would benefit a frigate with 2 2/12 year build time, but not a frigate with 2 3/12 year build time.
Well, regardless of the heavy industrial park, we do need clarification on whether planning is going to be moved to monthly granularity, or compromised to remain at quarterly granularity. And we need clarification on whether the heavy industrial park monthly saving occurs at the start of the build year (benefits repairs) or at the end.
