From the book "Heroes Beneath the Waves
USS GUAVINA SS-362
This is a chapter from the book Pacific
Patrol, self-published in 1993 by Marion Shinn. He tells his experiences in his own words on the last half of the fifth war patrol of the
submarine D.S.S. Guavina (SS362) in February 1945 (reprinted with permission).
It was Valentine's Day, 1944, when our boat
arrived at Cam Ranh Bay, off the coast of what was then French Indochina; but love and red hearts were far from our minds. The weather
was still bad, but the waves were not as vicious as we had experienced here the previous December. The electronic surveillance from the beach still caused interference on our radar screens, but
it was not persistent. The captain felt reasonably safe patrolling close to the beach. There was no little
patrol boats, only low- flying float planes continuing to search. They kept us submerged most of the
time.
Our assigned patrol station was familiar. It
was from Cam Ranh, past Phan Rang, to Padaran Cape, a forty- or fifty-mile coastline. For several consecutive days, we raced to
battle stations at 0730 hours. This was breakfast time, and we left our plates of food on the tables. The
captain made no attacks. The possible targets were either the tiny boats from the local ports or big ones
that were too far away.
On 20th February at 0730, the mess cook had
breakfast ready, and we had just started eating. The battle stations bell rang, "Bong, bong, bong" throughout the boat
just as it had for three or four days. Many of
us went half-hardheartedly to our battle stations. I thought a cold breakfast
wasn't the way to start the day.
I proceeded at a reasonable rate to my battle
station in the forward torpedo room. Put on my headset to the JP sound gear. As I rotated the sensitive listening head, I could clearly
hear the sound of the screws from a passing ship. The sound became closer and closer until it
appeared to be directly overhead. I thought it was odd there was no comment or action from the conning
tower.
I relaxed for a moment thinking maybe the
ship had left the area. Suddenly, I sat upright as orders came from the conning tower, "Stand by forward." I rapidly spun the
sound head around straining to hear the activity above the sea. Suddenly, the captain shouted, "Fire 1,
Fire 2, Fire 3, Fire 4!"
Tuesday, November 21, 2017
The search is
still on for our neighbor's boat. All of us in the International Community of
Submariners are praying for a good result of that rescue mission. Argentina is
a member of the International Submariners Association, and they do attend the
congresses.
Those, which have
gone down to the sea in a submersible ship know all too well that this could be
one of us fighting for our lives. Using our skills and experience to beat once
again the odds of ending up in Davy Jone’s locker. Our prayers are that the sea
is so rough that they are keeping their heads down in hopes of riding it out.
Thanks

(CNN)Sounds,
which were detected during the search for a missing Argentine navy submarine
did not come from the vessel; the navy said late Monday.
Noises that had been
detected earlier Monday were thought to be a possible distress signal from the
crew of the sub.
A US Navy P-8A Poseidon
aircraft was brought to the area to record an acoustic footprint of the sound,
but analysis of the file determined the noises were not from the missing
vessel, Argentine navy spokesman Enrique Balbi said from Buenos Aires.
The noises were possibly
from the ocean, or marine life and two vessels searching for the sub had heard
a "noise" at a depth of about 656 feet. The location of the noise
coincided with the route the submarine would have taken on the way to its home
port in Mar del Plata.
The sonar systems of the
two ships had detected noises sounding like tools being banged against the hull
of a submarine, according to a senior US Navy official familiar with the Navy's
assistance in the search for the Argentine vessel. The official said that crews
of submarines in distress bang on the vessel's hull to alert passing ships to
their location.
The missing submarine --
ARA San Juan -- has a crew of 44. The sub was heading from a base in southern
Argentina's Tierra del Fuego archipelago to Mar del Plata. It was scheduled to
arrive there Sunday.
'Failure' reported in the
vessel's battery system
The vessel's captain
reported a "failure" in the vessel's battery system shortly before it
disappeared last week, Navy spokesman Gabriel Galeazzi said.
After he reported the sub
had experienced a "short circuit," he was told to "change course
and return to Mar del Plata," said Galeazzi.
This type of problem is
considered routine, and the vessel's crew was reported safe, he added.
The Argentine navy had one
more communication with the captain before the sub went missing, said Galeazzi.
The Navy did not give details of the content of that final communication.
On Saturday, seven reported
communication attempts were initially believed to originate from the San Juan
-- but on Monday officials said the radio calls had not come from the missing
sub.
The last confirmed contact
with the submarine was Wednesday, the Argentine navy said.
The US official said that
the waters of the Atlantic Ocean where the sounds originated are extremely
deep. The official stressed that search efforts thus far have yet to locate the
submarine.
The Argentine military has
also been working with a US company that specializes in satellite communication
to determine the location of the submarine.
The search area, off the
Patagonia coast, is notorious for strong storms.
Clock is ticking
In the "worst-case
scenario," the missing sub could run out of oxygen in two days, Balbi
said.
Under normal circumstances,
the vessel has sufficient fuel, water, oil and oxygen to operate for 90 days
without external help, Balbi said, and the vessel could "snorkel" --
or raise a tube to the surface -- "to charge batteries and draw fresh air
for the crew."
If the sub is bobbing
adrift on the surface and the hatch is open, it will have an available air
supply and enough food for about 30 days, he said.
If it is immersed and
cannot raise a snorkel, oxygen may last about seven days. When the sub last
made contact on Wednesday, five days ago, it was immersed, Balbi said.
"This phase of search
and rescue is critical," Balbi said. "This is why we are deploying all
resources with high-tech sensors. We welcome the help we have received to find
them."
A large number of international ships
and airplanes, including a British polar exploration vessel, are braving strong
winds and six-meter high waves in the area off the coast of Patagonia where the
submarine was lost.
The rough conditions were shown in
footage posted online by the Argentinian navy on Monday. “These were the
meteorological conditions and the state of the sea yesterday in the search and
rescue operations zone,” the navy tweeted.
The US Navy has also joined the search,
deploying unmanned submersibles and airplanes to the South
Atlantic.
Two US air force planes landed in the
southern coastal city of Comodoro Rivadavia on Sunday carrying a US Navy
submarine rescue team, including a mini-sub, a submersible rescue vehicle and a
remote control unmanned submersible equipped with video cameras.
A British Royal Navy Hercules C-130
plane and the HMS Protector, ice patrol ship, are also participating in the
rescue effort.
Mauricio Macri met relatives of the crew
at the Mar del Plata naval base on Monday morning. The president said on
Twitter that the government was “deploying all possible national and
international resources to find [the crewmembers] as soon as possible.”
But the wait is taking its toll on the
relatives of the missing submariners. “Every day is leading us closer to a sad
ending, regrettably,” Carlos Mendoza, brother of crew member Fernando Ariel
Mendoza told the Infobae website. “It’s sad, but we have to be realistic.”
Karina Vargas, the wife of crew member
Cayetano Vargas, told the local newspaper San Juan 8 that she had seen her
husband in a dream after the submarine had left Ushuaia.
“I’ve never had a bad feeling before,
but this time I saw him arriving at home before time. He said hello, and I made
a joke about asking him to look after the boys so I could go out.”
Other family members have used social
media to ask for support during the search.
“Pray so that my husband Fernando Santilli can return home,”
Jesica Gopar said on Twitter. “He’s on the San Juan submarine.”
In another message, she tweeted a
picture of her missing husband, with the message: “Your son and I are waiting
for you. I love you.”

Launching a Missile From a Submarine Is Harder Than You Think
David Hambling, Popular Mechanics, February 13
Launching a missile from a submarine isn't as easy as pressing a big red button. It takes a lot of engineering and rocket science to ensure a missile gets from an underwater launch tube to streaking through low-Earth orbit at more than 13,000 mph—and sometimes, that delicate dance of physics can go wrong.
As these missiles increase in lethality, like today's Trident II D-5 missile, so do emotions surrounding the ethics of using such a weapon in the first place. But knowing Trident's future, and the future of other nuclear missiles, requires a trip to the past and an exploration of how you even launch a missile from under the sea. Here's how a missile makes it way through the water, into the air, and on its way to a target.
How We Got Here
Submarines couldn't always launch airborne missiles from under the sea, of course. During both World Wars, submarines were armed with torpedoes and deck-mounted guns—heavy cannons for engaging surface ships and lighter anti-aircraft weapons. Mine-laying submarines also terrorized the sea in the first half of the 20th century.
But at the dawn of the Cold War, it became clear that nuclear missiles would decide future world conflicts. The earliest versions of this technology—such as what went into the Nazi V-1 and V-2s, proto-cruise missiles used to bomb London—were used as a design starting point. These missiles had a range of just a few hundred miles, which meant you needed an aircraft or ship to carry them within range. A submarine with a capable missile carrier would be the perfect weapon, able to get weapons of mass destruction within incredibly close range of the enemy without being detected.
In 1947, the United States launched a JB-2 Loon, a direct copy of the German V-1, was launched from the deck of the submarine USS Cusk. This test proved it could be done, but the Cusk used an unpolished, jerry-rigged system. By 1953 the USS Tunny had been adapted into a true missile submarine, but firing the Regulus cruise missile was still an awkward process. The submarine had to surface, then the missile was manually loaded from storage onto a launch rail on the submarine's deck before it could fire. During the whole process, the surfaced submarine was visible and vulnerable to attack by enemy aircraft. The Grayback class of submarines were subsequently built to launch missiles from the surface.
At the end of the 1950s, weapons systems still had yet to master the tricky science of shooting a rocket through water. But technology was progressing quickly, and at the turn of the decade, the Navy developed the Polaris A1 Fleet ballistic missile. Successfully launched by the USS George Washington, this missile was a revolutionary development because it allowed a boomer, another name for a ballistic missile submarine, to remain submerged. Subsequent missiles have all been refinements of the same basic design, invisible and unstoppable.
Decades later, the ballistic missile submarine is still considered the most secure leg of the nuclear triad (land-, air-, and sea-launched nukes). And sub-borne missiles have only increased in range, power and accuracy. The original Polaris had a range of about a thousand miles and delivered a single 600-kiloton warhead with an accuracy of around a mile. In 1972 a new version entered service (originally known as the Polaris B3 but then renamed Poseidon C3) with had a range of almost 3,000 miles, and carried up to twelve warheads. In 1979 came the sea god's most trusted weapon—the Trident C4, which carried the same payload to a distance of 4,600 miles. It meant a sub in the Pacific could hit any target in the Soviet Union.
Today, American Ohio-class and British Vanguard-class submarines are equipped with a sixth-generation Trident weapons system. But perhaps more impressive than its awesome destructive capability is the mechanical process that launches the missile in the first place.
The Physics of a Launch
Made by Lockheed Martin, the current Trident II D-5 missile is a squat, blunt-nosed, 44-foot-long cylinder weighing nearly 120,000 pounds. It's fired by a steam cannon. First, an explosive charge flash-vaporizes a tank of water into steam. As the pressure of the expanding steam drives the missile out of its launch tube, it provides enough momentum for the weapon to clear the water's surface. This cocktail of high pressure and dangerous explosives is a crucial phase of every launch. Multiple safety mechanisms are in place to deactivate the missile if it fails to get away from the sub.
The missile slows down as it leaves the water and gravity tries to pull it back down. Motion sensors monitor the changes as the missiles hang in the air for a brief moment before the first of three rocket stages ignites.
Here, things can go spectacularly wrong if you're unlucky. Trident's first test launch from the USS Tennessee in 1989 failed because the plume of water trailing behind the missile interfered with a rocket nozzle. The resulting asymmetric thrust sent the missile spiraling in a spectacular pinwheel lasting four seconds before ending in a shower of flaming debris.
If all goes well, though, the first stage rocket burns for 65 seconds. During this phase, the missile extends an aerodynamic spike to smooth the airflow over the blunt-nosed cylinder. Without this spike, the missile can't survive its brief, high-speed transit through the atmosphere.
Finding Its Target
During this first minute, the missile should now be well on its way. It will eventually reach 600 miles above sea level. The remaining rocket stages still need to ignite, separate, and remain on the correct trajectory.
Again, this isn't so easy sometimes. According to a recent leaked report, a British Trident missile launched off the coast of Florida in June 2016 as part of a testing program was supposed to head east toward a target site near Africa. Instead, the missile allegedly veered east toward the U.S. before it was destroyed.
If the missile stays on the correct path, Trident then navigates with an inertial guidance system, based on a set of sensitive accelerometers measuring precisely how much the missile accelerated and for how long. An onboard computer uses this data to calculate speed and position of the missile. In most military technologies, inertial guidance has been replaced by GPS because the older way is expensive and has a tendency lose position over time. But that's not such a huge problem when your flight is only a few minutes long. The U.S. Navy has never fired a GPS-equipped Trident, largely out of fear of possible GPS tampering.
Because of the internal guidance system's limits, Trident also has a star sighting navigation system. Like an old-time sailor, this sensor gets a location fix by measuring the position of the stars to provide fine detail correction. This correction may be needed because the orientation of the submarine may not be precisely known at launch. A compass can be thrown by magnetic disturbances, and conditions at Earth's poles (where subs sometimes operate) don't help things either. Even odd gravitational anomalies may be great enough to throw the missile miles off course, so missiles—as well as Navy seamen—are well-versed in reading the stars.
Once all those stars align, the missile finally streaks toward its deadly destination.
Coming In For a (Destructive) Landing
As the missile approaches, it ejects twelve independent warheads at different targets. Each warhead has a yield of 100 kilotons—six times greater than the Hiroshima bomb. The missile's accuracy is quoted as less than 400 feet Circular Error Probable (CEP), meaning there is a 50 percent chance it will land less than 400 feet from the target.
But everything has to function perfectly for the missile to hit a target, and a glitch at any stage can be disastrous. There is also the new hazard of cyber sabotage of nuclear delivery systems. Malicious software, or even hardware which interferes with the missile controls, is a cheap way of disabling a nuclear deterrent. Although it sounds unlikely, such an attack wouldn't be without precedent.
The Royal Navy's latest botched test has only renewed calls from nuclear opponents who would like to see these destructive monsters of the deep retired completely. But as long as nuclear weapons exist, it's likely that that the Trident is going anywhere anytime soon.

In 1947, the United States launched a JB-2 Loon, a direct copy of the German V-1, was launched from the deck of the submarine USS Cusk. This test proved it could be done, but the Cusk used an unpolished, jerry-rigged system. By 1953 the USS Tunny had been adapted into a true missile submarine, but firing the Regulus cruise missile was still an awkward process. The submarine had to surface, then the missile was manually loaded from storage onto a launch rail on the submarine's deck before it could fire. During the whole process, the surfaced submarine was visible and vulnerable to attack by enemy aircraft. The Grayback class of submarines were subsequently built to launch missiles from the surface.
At the end of the 1950s, weapons systems still had yet to master the tricky science of shooting a rocket through water. But technology was progressing quickly, and at the turn of the decade, the Navy developed the Polaris A1 Fleet ballistic missile. Successfully launched by the USS George Washington, this missile was a revolutionary development because it allowed a boomer, another name for a ballistic missile submarine, to remain submerged. Subsequent missiles have all been refinements of the same basic design, invisible and unstoppable.
Decades later, the ballistic missile submarine is still considered the most secure leg of the nuclear triad (land-, air-, and sea-launched nukes). And sub-borne missiles have only increased in range, power and accuracy. The original Polaris had a range of about a thousand miles and delivered a single 600-kiloton warhead with an accuracy of around a mile. In 1972 a new version entered service (originally known as the Polaris B3 but then renamed Poseidon C3) with had a range of almost 3,000 miles, and carried up to twelve warheads. In 1979 came the sea god's most trusted weapon—the Trident C4, which carried the same payload to a distance of 4,600 miles. It meant a sub in the Pacific could hit any target in the Soviet Union.
Today, American Ohio-class and British Vanguard-class submarines are equipped with a sixth-generation Trident weapons system. But perhaps more impressive than its awesome destructive capability is the mechanical process that launches the missile in the first place.
The Physics of a Launch
Made by Lockheed Martin, the current Trident II D-5 missile is a squat, blunt-nosed, 44-foot-long cylinder weighing nearly 120,000 pounds. It's fired by a steam cannon. First, an explosive charge flash-vaporizes a tank of water into steam. As the pressure of the expanding steam drives the missile out of its launch tube, it provides enough momentum for the weapon to clear the water's surface. This cocktail of high pressure and dangerous explosives is a crucial phase of every launch. Multiple safety mechanisms are in place to deactivate the missile if it fails to get away from the sub.
The missile slows down as it leaves the water and gravity tries to pull it back down. Motion sensors monitor the changes as the missiles hang in the air for a brief moment before the first of three rocket stages ignites.
Here, things can go spectacularly wrong if you're unlucky. Trident's first test launch from the USS Tennessee in 1989 failed because the plume of water trailing behind the missile interfered with a rocket nozzle. The resulting asymmetric thrust sent the missile spiraling in a spectacular pinwheel lasting four seconds before ending in a shower of flaming debris.
If all goes well, though, the first stage rocket burns for 65 seconds. During this phase, the missile extends an aerodynamic spike to smooth the airflow over the blunt-nosed cylinder. Without this spike, the missile can't survive its brief, high-speed transit through the atmosphere.
Finding Its Target
During this first minute, the missile should now be well on its way. It will eventually reach 600 miles above sea level. The remaining rocket stages still need to ignite, separate, and remain on the correct trajectory.
Again, this isn't so easy sometimes. According to a recent leaked report, a British Trident missile launched off the coast of Florida in June 2016 as part of a testing program was supposed to head east toward a target site near Africa. Instead, the missile allegedly veered east toward the U.S. before it was destroyed.
If the missile stays on the correct path, Trident then navigates with an inertial guidance system, based on a set of sensitive accelerometers measuring precisely how much the missile accelerated and for how long. An onboard computer uses this data to calculate speed and position of the missile. In most military technologies, inertial guidance has been replaced by GPS because the older way is expensive and has a tendency lose position over time. But that's not such a huge problem when your flight is only a few minutes long. The U.S. Navy has never fired a GPS-equipped Trident, largely out of fear of possible GPS tampering.
Because of the internal guidance system's limits, Trident also has a star sighting navigation system. Like an old-time sailor, this sensor gets a location fix by measuring the position of the stars to provide fine detail correction. This correction may be needed because the orientation of the submarine may not be precisely known at launch. A compass can be thrown by magnetic disturbances, and conditions at Earth's poles (where subs sometimes operate) don't help things either. Even odd gravitational anomalies may be great enough to throw the missile miles off course, so missiles—as well as Navy seamen—are well-versed in reading the stars.
Once all those stars align, the missile finally streaks toward its deadly destination.
Coming In For a (Destructive) Landing
As the missile approaches, it ejects twelve independent warheads at different targets. Each warhead has a yield of 100 kilotons—six times greater than the Hiroshima bomb. The missile's accuracy is quoted as less than 400 feet Circular Error Probable (CEP), meaning there is a 50 percent chance it will land less than 400 feet from the target.
But everything has to function perfectly for the missile to hit a target, and a glitch at any stage can be disastrous. There is also the new hazard of cyber sabotage of nuclear delivery systems. Malicious software, or even hardware which interferes with the missile controls, is a cheap way of disabling a nuclear deterrent. Although it sounds unlikely, such an attack wouldn't be without precedent.
The Royal Navy's latest botched test has only renewed calls from nuclear opponents who would like to see these destructive monsters of the deep retired completely. But as long as nuclear weapons exist, it's likely that that the Trident is going anywhere anytime soon.

HEROES BENEATH THE WAVES; SUBMARINES STORIES OF THE TWENTIETH CENTURY
The unbelievable stories of the heroic men who sailed under the sea.
In Heroes Beneath the Waves, many brave men who rode submarines to great depths and across the oceans into unknown territory share their experiences, fears, and thoughts. They allow us to travel back in time through their memories. Trained for years to keep silent—for “loose lips sink ships”—many still believe what they know to be classified and refuse to disclose even the minutest of recollections. Others, however, want to leave a legacy of reminiscences for people to learn and live by—to know that freedom is not free.
Some stories will never be told. Held within the secret confines of their souls, these deep sea veterans block them out for self-perseverance. Yet, there are others who will never escape their own minds; they relive their underwater experiences over and over with eyes open or shut.
Heroes Beneath the Waves is about teenage boys who left farms, small towns, and inner cities to defend the United States and democracy worldwide. Signing up for United States Navy submarine duty was an adventure of a lifetime during the early 1940s. Dreams of torpedoing Japanese and German ships and subs consumed their thoughts. Those who returned home as young men were older and wiser. Heroes Beneath the Waves was written to honor these men—gallant heroes—who served and are serving today on submarines.
Skyhorse Publishing, as well as our Arcade imprint, are proud to publish a broad range of books for readers interested in history--books about World War II, the Third Reich, Hitler and his henchmen, the JFK assassination, conspiracies, the American Civil War, the American Revolution, gladiators, Vikings, ancient Rome, medieval times, the old West, and much more. While not every title we publish becomes a New York Times bestseller or a national bestseller, we are committed to books on subjects that are sometimes overlooked and to authors whose work might not otherwise find a home.
