The Naval Undersea Museum Exhibits Director, Ron Roehmholdt, is well aware of the unsightliness of the two (and actually the Sturgeon sail also, but it is dark and hids the crud better).  The problem lies with the Navy, the work HAS to be done by contract - I already volunteered last year if needed but we wouldn't be able to get past the Navy "burro-crats".  The museum does "own" all those things, since the Navy owns the museum - also and the land that it sits on.  The museum is run by a combination of Navy funds and a foundation that was set up in years past.  Not a great answer "but" it is a good Navy answer - LOL...

thanks John   I figured as much and I did see the sail and the Sea Lab Hatch as well. I wonder if their isn't some other way to get the okay maybe Base CO, since the are Navy owned. Anyways I thought I would ask. I could ask my son (he is a Fire Captain in the ship yard) maybe they could declare them to be on fire and use the different engines to put them out. or maybe use the parking lot some Tuesday for just training or competition.  Thanks Again  I just thought it might make for a helluva an outting for all the SubVets to participate and help save a few bucks, Just like Crusader in NAD Park lots of people want to take care of it and it is hopelessly mired in Red tape. I will probably be out their nest Weds if I don't get to go on Mon

Bear (etal) - Here is an answer directly from Jennifer (Museum Specialist) at the museum...

There are contracts out to bid on the outdoor artifacts.  I wish it was as simple as taking a pressure washer to it, but there would be nothing left of the artifact.  The company builds scaffolding around the structure to meet OSHA code (there are a lot of contaminates we want to contain).  Archival, non-abrasive, non-corrosive products are used to remove paint, inhibit the rusty areas, barrier sealer is applied, paint (again archival brand), and another barrier.  The structures are also reviewed for structural safety by a structural engineer. 

I appreciate the kind offers, but washing moss off and putting a coat of paint on just hides the problem, rather than preserving the artifact.  I hope the contracts will go through by August.
