South River resident was part of a discovery team that recently
located a sunken German submarine.
The final resting place of the World War II German submarine
U-550 was discovered on July 23 in deep waters off the coast of
Nantucket Island, Mass.
The sub was one of the last undiscovered German U-boats sunk off
the American coast in 1944.
It was finally located using photographic and sonar imaging by
an expedition team of Steve Gatto, Garry Kozak, Joe Mazraani,
Tom Packer, Brad Sheard, Eric Takakjian and Anthony Tedeschi.
“We were screaming, happy, high-fiv ing each other, giggling
like schoolgirls,” Mazraani, of South River, said.
to information provided by Mazraani, on April 16, 1944, the
U-550, a type of IXC/40 long-range U-boat under the command of
Kaptitanleutnant Klaus Hanert, put a single torpedo into the
stern of the 10,017-ton American tanker Pan Pennsylvania. The
Allied tanker was in convoy and bound for England loaded with
140,000 barrels of gasoline at the time. Following the torpedo
explosion, the ship took on an immediate list to port, and when
a fire broke out in the engine room, the tanker was abandoned in
The convoy escorts picked up 56 survivors, leaving 25 men
missing out of a crew of 81. After picking up the survivors from
the Pan Pennsylvania, the U.S. Navy destroyer escorts USS Joyce,
Peterson and Gandy combined their efforts to bring swift and
fatal retribution to the attacking submarine.
Picking up a solid contact with its sonar gear, the Joyce closed
in on the target and made a depth-charge attack that quickly
brought the U-550 to the surface. Gunfire from all three escorts
converged on the surfaced submarine as German sailors poured out
of its hatches, briefly returning fire with their own weapons.
the Gandy rammed the submarine aft, and the Germans abandoned
A muffled explosion aboard the submarine indicated the crew had
set off scuttling charges, and the U-550 sank stern-first.
Twelve survivors from the submarine were picked up by the
destroyer escorts, while 44 men were lost. Patrol boats picked
up the bodies of three German sailors outfitted with escape gear
during the next several weeks; they had apparently escaped the
sunken submarine only to die adrift at sea.
The tanker Pan Pennsylvania capsized and drifted for two days,
its cargo of gasoline on fire, before finally being sunk with
The mission to look for this particular sub began more than four
years ago. Mazraani met his fellow team members on local dive
boats off the coast of New Jersey. He has always had an interest
in history combined with exploration, and a fascination with
submarines. He said he read about this specific battle about 13
years ago and always thought about looking for it.
An attorney in North Brunswick, he also has his own charter
business, AWS Expeditions, which does diving for shipwrecks. His
45-foot boat Tenacious was used in the search for the submarine.
The research and trip planning took years, but the first
surveying trip was in July 2011, followed by this past trip.
Mazraani said that July has the calmest weather, but only a few
days are calm enough to take the boat out for the 75-mile trip.
“The location of the sub is so far away that you can only go
when the weather patterns are best,” Mazraani said.
So, last month the men spent four days surveying at very slow
speeds. They used a site-scan sonar device that is attached to a
cable and transmits information to a computer, which reads the
sound waves that bounce back when they hit an object. The size
of the object can then be compared to the size of the known
Mazraani said that there were two false alarms last year and
this year, since there are a lot of rocks, shipwrecks and debris
on the ocean floor.
This time, however, they found what they had been searching for,
and dove down to the submarine. It was found lying mostly intact
on the ocean floor with an approximately 45-degree list to
However, because it is a war grave and people are entombed in
it, the structure cannot be touched.
“It’s exciting to see a plan unfold, and unfold so
successfully,” Mazraani said of the mission’s completion. “This
will provide closure to the families — the German families, the
American families, the families of the people on the tanker that
The men did take photographs, videos and measurements, and the
information will now be shared in books, in newspapers, on the
Internet and on U-boat websites.
