Hunter's Point hasn't been a naval shipyard for over a decade.
Right now it's just a huge, empty, nothing, with an enormous toxic waste problem.
Longer, I thought. 1970s for parts of it?
I don't mind redevelopment so much as what looks like the flavor of it. SF rejected the Iowa, which would have fit right in the drydock she used to be overhauled in repeatedly. I can guarantee you that there will be no war museum honoring the people who worked there, or the fact that the atomic bombs left from that yard after development work was done there. I doubt they'll preserve things like the optical building where people proofed periscopes for subs in WWII by sighting on city landmarks. (I've seen photos of that, it's still there)
From the hippie features to the "public housing projects" to the choice of a questionable developer known for cutting corners, it looks like it's going to be a typical bit of taxpayer-funded liberal fail. And that, to me, is rather sad for a place that was so important to the war in the Pacific. Deserves a better fate after cleanup, with a battleship on display and a museum at least.
SO, the armed services are closing down and giving away all these shipyards, based, etc.
So, when the next existential conflict arises, where do they think they are going to train the men, build the ships, train the pilots, etc?
They aren't all closing. Portsmouth Naval Shipyard here just got a massive infusion of funds for an updated Los Angeles-class submarine overhaul and fueling facility. I expect some others have had the same.
