Assunto: New Mystery Picture @ uss-salem.org

A new mystery picture, and the answer to the previous mystery picture,
have been posted at http://www.uss-salem.org/features/mysteries/

The correct answer to the previous picture was:

                      USNSM Mystery Picture #79 Answer

 This is the liner SS Liberte, formerly the troopship USS Europa (AP 177),
  originally the German liner SS Europa, sunk at Le Havre, France, after 8
 December 1946. Answers stating either "Liberte" or "Europa" were accepted
                                as correct.

 Europa was built by Blohm & Voss as a passenger liner, completed in 1930.
On the outbreak of WWII she served the German military as an accommodations
  ship, and by June of 1940 it was planned to use the ship as an invasion
    transport. Instead, she was designated for conversion to an aircraft
 carrier, one of series of five liners and cruisers so designated in May of
 1942. She would have been the largest of the five converted carriers, but
  in the event no work was carried out, and plans for her conversion were
                        abandoned 25 November 1942.

  Europa was taken as a US prize 8 May 1945, following Germany's collapse.
 She was placed in commission as USS Europa (AP 177) on 25 August 1945, and
     made three trans-Atlantic trips to ferry US troops home. She then
  decommissioned 2 May 1946 and was transferred to the US State Department
   for further transfer to France as war reparations. Before she could be
  placed in service by the French she was wrecked and sunk at Le Havre, 8
 December 1946, as seen here. She was raised 15 April 1947, reconditioned,
   and returned to service 17 August 1950 as SS Liberte. She was finally
                             scrapped in 1962.

    Correct answers were received from: Mark Lawden, Michael Hughes, Tom
     Stoodley, Barry Gerrard, Pete Randrup, Jeremy Dennis, Dorian Jung,
 Christoph Peeters, Don Rodeniser, Joe Donahoe, Mark Stockwell, Mike Green,
                        Mark Tripp, Sal Mercogliano

Sorry, this may be untrue. I heard this on CNN, apparently from some State

i read somewhere that the Japanese goverment asked for US military
assistance but the military said they didn't have the resources
available....

my question is: doesn't the navy or air force have nuclear response teams to
deal with situations with their reactors and warheads?

 It wasn't a reactor accident.  The incident happened at a Uranium fuel
enrichment plant.

The hydrodynamic drag is dependent on hull length, even for hulls of identical
fineness (length/beam.)  This is because the period of the bow wave is
dependent on hull length--shorter hulls pile up steeper hills.

So the longer ship may be more efficient at the same speed.

Well, the bow wave is there as long as the hull is moving, regardless of
whether it's screws or inertia that's pushing it.  To move, it has to
displace water.  When you stop engines, the ship begins to slide back
down the 'hill' that it's climbing.  As it decelerates, it's no longer
pushing water up in front of it as fast, and the bow wave collapses.  This
is the physics that helps make the curve so non-linear.

However, for similar hull shapes, I think the curve should have the
same general shape, so

>   All whatever happens
>during the measured 4 cables for the one so can we ignore it all and just

Yes, I think you can, but because the speed/power/drag relationship is
non-linear, one point is not sufficient to determine the curve.  If it
were linear, you could do it with one speed/hp point and compare the
two.  But it's not...

I am old enough that this is how I was taught

Rick, please READ what I wrote (quoted above).  Please READ that I
wrote 'too fast a reversal'.

The subject under discussion is NOT controlled transition to going
astern, but crash backs, another matter entirely.

In the USN at least, a "crash back" is the same thing as "controlled
transition to going astern".  There's nothing 'uncontrolled' or 'too fast'
about it.  Even if you order 'back full' from 'flank ahead', you're not
going to break anything - trust me, been there, done that, and described
it already in this thread.
