The Last Hours
of USS Whitehurst DE-634
USS Trigger SS-564 Successfully Tests Mk-48 Torpedo
The story as told by veterans of USS Trigger. i.e. The "Men
Who Were There"
Wayne and Max;
I was on board Trigger the day she sank
the Whitehurst (it was my birthday).
Trigger, along with USS Trout, were
providing support for Westinghouse and
Clevite for the development of the MK 48
torpedo. The testing took place near
Bangor, Washington and Nanaimo,
British Columbia on Vancouver Island. It
was a great experience -
beautiful countryside, good beer and gracious
especially the PPCLI (Princess Patricia's Canadian Light
provided us with barracks. Your e-mail brought back some good
Whitehurst was one of three live war shots made by Trigger off the
Washington. I have photos of the MK 48 used and the Whitehurst,
before the war shot and one taken through the periscope as she was going
down. ... The 48 being loaded is the one actually fired at the Whitehurst. The
artist painting the silhouettes on the sail is me (in preparation for our
return to San Diego). Photo #4 was taken in San Diego.

I was aboard the USS
Trigger SS-564 when we fired the first "live" MK-48
Torpedo at the
Whitehurst. We could hear the breaking up sounds, on Sonar,
just like the
movies. I'm fairly sure there were pictures of the ship broken in
sinking. But I have no idea of where they might be. I do have a
Award Certificate that is signed by the CO of the Trigger, the
Westinghouse, and the acting CO of the Whitehurst.
Ref your request of
photos of the Whitehurst sinking...here are three of the event.
I was a TM3 on board the
Trigger during the Mark 48 Torpedo Test and Evaluation
firing in 1971. I
was part of the torpedo gang that loaded it up, fired it, and waited
demise of the Whitehurst after a nine minute run.
It was a Westinghouse
Mark 48 Mod 0 that sunk the Whitehurst. We were testing
48's. The Mod 0 and Mod 2 by Westinghouse and the Mod 1 by
Cleveite. It was a shoot out of sorts between the two companies and
the contract. But, the one that sunk the Whitehurst was the
first Mark 48 war shot
The torpedo detonates
under the ship and the upward force breaks the vessel in
two. The stern
sunk first and then the bow. We were able to get close enough to
photo of the bow just before it went under. Each crew member was given a
copy of the photo taken through the periscope. Many official photos were
through the scope.
Also the whole event was
photographed from a helicopter taking 16mm movies.
They took movies of us
on the surface and of the detonation and sinking of the
bow. I know because a couple of months later, I had the job of
down a copy of all that film footage from two big reels down to a small
presentation that the CO used at various presentations related to the
we went through.
note: I submitted a request for
the photos but the National Archive
personnel could find no photos of Whitehurst's sinking. They gave no
reason. It would seem the pictures should have been declassified since
almost 40 years had passed.

The other two photos
attached are of me sitting in front of the tube that we fired the
third shots from (see the American flags on the tube door - a take off of
the subs keep score during WWII) and of the "Kills" painted on the
Unfortunately, that is
all I have reference the Whitehurst, except that I do have the
gravy bowl from the ward room (and you are not getting that). The
hurst was tied up in front of us just prior to leaving port of the
shoot. Since it was a
target ship, we were given permission to go onboard
and collect any "souvenirs".
As I was rummaging through the
ward room, I pulled open a drawer and there was
a badly worn and
tarnished gravy bowl
(I had it replated and it looks good).
We also disassembled the
barber chair that was in the after steering room and huffed
and puffed the
thing up, out and over to the Trigger as we thought it would look good
of the after torpedo tubes. But, after all that work, it would not fit
hatch. The base was an inch wider in diameter that our hatch

I was the periscope photographer on TRIGGER when we sunk your ship and have
a copy of that picture. I can email it to you when I return from the
east probably towards the end of September. I believe my photo is
National Archives as well. I can also tell you about the event especially
the towing of WHITEHURST to Bangor and the night before we sank her when
Trigger's crew stripped her portholes and other stuff. Please keep my
and email handy.

I was a TM on
the Trigger when we tested a war shot Mk. 48 torpedo that sunk the
Whitehurst... Also, I believe R.J. Hansen was on board then.
R.J. is now an officer
in the reserve, I think, and I believe regularly
attends the Trigger reunions. R.J. was
a TM3 at the time. I'm
certain he would have a copy of the photo. That was the only
photo I saw
of the sinking. There was a tin can that accompanied us on the shot,
though I do not recall the name. They tried to finish up the Whitehurst
with a deck
gun, though it sank too quickly for them to get in range .
I Hope this
help. Sure, you can use my comments. The photo of Henry's is the
was thinking of. It was weird too, because we had a copy of the
film "The Enemy
Below" on board which I believed used the Whitehurst
and was sunk (on film) at
the end of the movie. The tin can that tried to
finish it off with her deck gun I believe
was the USS Fox, a DLG, but I could
involved with the Mk. 48 torpedo evaluations - we spent about 6 months test-
them in the Strait of Georgia off Vancouver Island. When we cleared the
Juan de Fuca to conduct the war shot, we ran into a huge storm.
It didn't bother me,
but about 1/3 of the crew was sea sick. The storm
passed and we completed the war
shot. It was really strange to hear the
detonation under water. I remember surfacing
and watching the tin can try
to shoot down the bow of the Whitehurst, walking out
the shots to find the
recall sinking any other ships. I think we only conducted one war
also planned on using a scrap decommissioned sub as a target
as well, but it sank
on the tow up from San Diego. Terry
I was on the
Trigger (SS-564) from early 1970 until June 1972. During my tour, we
tested the Mark 48 torpedo system. I even still have a
"Participation Award" signed by
CDR Flather who was the skipper
of the Trigger, a fellow named G.R. Thomas who was
the program manager for
Westinghouse, and D.A. Kohl, C.O. USS Whitehurst (Acting).
during those tests, as I recall, we sank the Whitehurst and 2 Liberty ships,
all specially prepared for the tests in Bremerton, WA and towed
out to sea for the event.
The attached photo is the bow of one of
those three ships in its last moments. It looks
like a destroyer bow to
me, but I'm really not sure if it's the Whitehurst or one of the
ships. Maybe you can tell for sure*. The photo was taken through
cope, as you can see by the cross hairs. There wasn't much time
detonation and sinking, so from the Trigger's point of view,
this was all the photos we
could get, I think. Good luck!

I am sure this is
Whitehurst. Why? The hawse pipe is in the correct
chocks for the mooring lines are also correct. The
markings for the water line just aft
of the stem also appear to be
correct. Lastly, Whitehurst had a strait bow (no rake)
and the keel was
flat and joined the bow at right angles. I recall this from the time she
was in dry dock. I look forward to your write-up.
Good luck , Roger

as Gunnery and Operations Officer
Sure, you are welcome to
use what I sent. I wish I had more for you. It's been a long
ago and memory fades!
I do remember that the
"target" ships were all fitted with various sensing gear to mea-
the effectiveness of the weapon. I also remember that the Mark 48 did not
trate the hull of the target. It detonated under the keel. The
effect was devastating.
Each target broke into two pieces which sank
independently. We shot from 5,000 yards
at 500 feet, so by the time we
could surface and close the range for a good look, it was
too late. Henry
