Flushing oil into the sea. Weren't they concerned about the environment?

As noted in a later comment, the 21000 NM range is apocryphal (and probably meant to be KM), standard was 11000. One wonders what similarly sized vessels the original questioner had in mind. The Gato class had a surface displacement of 1510 tons, the essentially contemporary Gridley class weighed in at 1570 tons. Endurances were 11000 NM at 10 kt and 7000 NM at 12 kt. Slowing the DD to 10 kt would have extended its range by possibly 1000 NM, and the difference is easily explained by the much better efficiency of the sub's diesels compared to the very high pressure steam plant in the destroyer.

Great Article thomally!

a LOT more Oil seeps up naturally in the sea bed per year than all spillage by humans.

Great article here:

I agree; nice article OP.

BTW guys, the COP natural seep releases 25 tons per day; Exxon Valdez released 37,000 tons in several days. Big difference in the rate of accumulation, and presumably in the ability of the environment to cope. We already know that oil exists in the wild (that's where it comes from after all).
