    Default Yamato

    battleship Yamato rests 1100 ft beneath the South China Sea

    but the legacy of Yamato and Musashi are very much alive--

    so a partial 1:1 scale mock up of Yamato was constructed around 10 years ago in Hiroshima Prefecture--and still stands-
    it was used to film a domestic production --Yamato--not one of the ships 18 inch main guns was put into action in the production---with japanese skill in computer graphics--a major disappointment

    JHolland1,

    I'd like to recommend a book with a lot of detail about the challenges of constructing the Yamato class:

    Amazon.com: Battleship Musashi: The Making and Sinking of the Worlds Biggest Battleship (9784770024008): Akira Yoshimura: Books

    The translation into English is awkward in a few places. (The propeller shafts are referred to as "axles", etc.) Some of the notes on the drawings aren't translated at all - they are still in Japanese. Overall, it was an interesting read from both a historical and technical point of view.

    greetings John

    25 years ago I employed the kind services of two Seattle machine dealers to sell my tools--
    -- around 1990 one dealer purchased an estimated two thousand tons of pre WWII machine tools from Japan
    upon viewing these I froze--an instant sensation of foreboding--
    very large horizontal and vertical boring mills, turning machines appearing to be dedicated to munitions, etc were packed in his main building--majority labeled "Nippon" and dated in 1930's
    even weirder-- they had the yellow-brown patina of japanese field uniforms of the time

    as it turned out--foreboding was well founded--a bankruptcy auction was held to dispose of these-and much more desireable
    equipment

    There has been considerable discussion in several boards about whether or not Yamato or Mushashi would have bettered an Iowa class BB, pretty interesting stuff. One has to wonder how much of it is nationalistic bias but the main point is that the Iowa's had much better range finding optics and computers, and that the mighty 16's would reach nearly as far. Two battleships closing at 30 knots would change the distance pretty fast, and Japanese nationalism probably would have demanded a full charge assault whereas full retreat while maintaining the distance in that margin would be a winner for the 18" guns.
    I don't know enough to argue about it but it is interesting, they also talk about the armor on the Iowa's as being a deciding factor.

    A nice model in the museum. If made out of metal it must weight a ton.

    The history of battleship engagements seems to prove that ANY battleship that receives hits from guns comparable to its own is in trouble. Armor is almost a non-issue. Inevitably hits will affect important auxiliary (non-weapon) things like rudders. Perhaps ranging equipment may be damaged, hits may jam turrets, cause fuel leaks, or cause some significant troublesome flooding, so that the key seems to be to be the first to hit, and use that advantage to the max.

    Probably that is one reason why the type is obsolete. Expensive, limited range of engagement, surprisingly vulnerable, may need long repair times for "minor" damage, and offers no other advantage justifying the cost. And the cost limits the possible numbers you can build.

    There were battleships, cruisers, destroyers, whole fleets of other vessels, capitol and otherwise....then came aircraft.

    ..then came aircraft.

    And then came nuclear ballistic missle submarines. Major shifts in defense strategy, more major expenditures for grand kids to pay for, but at least they are defended.



    It would be so fun to see how they rifled the 18X45 barrels. It's said that barrel life in any case was expected to be only 150 rounds max so they weren't used often even on the few rare occasions when they did venture out.

    There is much talk about what a massive national treasure these two BB's were in the scheme of things, so much so that most of their lives were spent in protected harbors.
    As a pivotal object of national defense there are still ships like that, our aircraft carriers and subs are fantastically expensive yet the DOD likes to use them to extend power, so our military tries to get the most bang for the buck.

    Grateful thanks to all who served our nation's defenses!

    Korea and Vietnam showed that, at that time at least, the battleship still had a very useful role; relatively cheap (per shot) shore bombardment.

    Very effective, North Vietnam required the withdrawal of the New Jersey before "peace" talks began. Those big guns could drop 2500 lbs of hate within inches of where it was aimed every time, Bonus, no loss of aircraft or crew.

    Anyone else notice that the wake of New Jersey is much more pronounced in that photo?

    I got to go into her machine shops long time ago. Sailor named Green took me down there because I emboldened myself to ask.

    OOps! Iowa not NJ.

    True but it was not like either of those sides had anything that could be effective at fighting back. The US did not go and try bombarding Russian soil when they knew Russia was fully supporting both North Korea and North Vietnam, as they knew their ships would not be floating for very long afterwards.

    Bit like modern aircraft carriers. Their effectiveness against an equivalent foe is near zero as they have little defence other then range against hypersonic anti-ship missiles.

    Now that we got our history lesson for the week.

    Anyone would know what kind of machine shop Japan had aboard this ship? Or any of the ships they had in the fleet back then?

    All those anti-aircraft guns. Yet, she was sunk by air attack. Things change. Regards, Clark
