    Notice they are sectional, You can divide them up for smaller craft, or add sections for larger ones. Luckily the PanaMax rule meant they only had to be so wide.

    These projects were started due to the limitations on bases imposed by the pre-war treaties (Washington, etc.) Because the US had a lot of space to patrol but could not build new bases, the Navy started looking into mobile bases and had a decent idea of some things to do when the war broke out. In a way, the limitations imposed by the treaties forced the US to innovate in ways that put us ahead of other nations.

    thanks for the info..very good....seems like a good deal, since it was cheaper - [and faster?? ]to build the Floating Docks than the bases?? therefore much less logistics needed? and they were ''mobile''....

    Another point was that the support units moved forward when the rather liquid "front" moved. In the run up to Olympic Nimitz was planning to "roll up" his rear areas and move supply, repair, etc., to Luzon, Okinawa, etc. Leaving a permanent dry dock behind that only seen a year or so service would have been very wasteful. If the bombs hadn't dropped, some of the floating drydocks would have been anchored off Kyushu, and eventually in the Sagami Wan.

    Nice pictures.

    Ulithi is worth a thread or two by itself. I think it went from being the busiest naval base in the world back to a deserted lagoon in a matter of months after everything sailed or was towed away.

    How many ships can you fit into a floating dry dock?

    Morrison used it, but it was an official USN photograph.

    I'm not sure how many floating drydocks the Navy had in the Pacific, but compared to the total number of ships, I'm sure there was a need to make maximum use of them. If they had mulitple ships that needed to be out of the water for about the same time, it would make sense.

    Another advantage of floating docks was that the construction could be done in the United States rather than having to ship all the men, materials, and equipment to build docks to the forward areas.

    And you have to build a cofferdam around the dock before you can dig it out. A lot of dirt to move, including, in the PTO, a lot of coral.

    A great thread. A lot of good information. The pictures alone are worth the price of admission. Thanks to all.

    I think one of them is still in operation in Norway, I think.
