98 Years ago–the E-2 blows up in Dry Dock

Lost Subs | Posted by Rebekah

(I wanted to post this in commemoration of E-2’s explosion, 98 years ago today…I made it with 15 minutes to spare.  Pics will have to come tomorrow…I’m too tired right now!)

 

Early in submarine history, submarines were more of working laboratories than anything else.  The men manning these boats were constantly working at the bleeding edge of science, and deadly consequences occurred with no enemy other than the basic forces of nature and chemistry.

Case in Point: the USS E-2.

Originally named “Sturgeon” while under construction, the re-named “E-2” was commissioned on 14 February 1912, just a few weeks before the other great Technical nautical wonder, the Titanic, would set sail on her maiden and final voyage.

She served for a number of years, patrolling around the New England coast, then Guantanamo Bay and the Gulf of Mexico.

Like most submarines, E-2 was an engine/battery submarine.  While on the surface she would run on her diesel engines (E-2 was one of the first to run on diesel, rather than the more unstable/explosive gasoline engines) and these engines would charge her batteries.  Unlike the engines, the batteries, producing no fumes and needing no oxygen, would run the submarine’s systems while underwater.  When the batteries ran out, the sub had to surface.

The trouble with these wet-cell batteries, however appeared frequently and caused some limitations in maneuvering. Submarines could only dive and surface at less than a fifteen-degree angle or the batteries would have trouble.  Any salt water at all hitting the batteries would cause deadly chlorine gas to form, asphyxiating the crew or even, causing an explosion.

In fact, the first sub fatality in the American Navy, the F-4, in 1915, was partially caused by a corroded battery case, leading to a loss of control, and implosion during a dive.

These issues lead American Inventor, Thomas Edison, as Chairman of the Naval Advisory Board,  to invent a new battery that would be more stable, less prone to the angles of a submarine’s dives and ascents, and eliminate the chlorine gas.  After five years of work, he believed he had a stable working model, which was photographed and proclaimed from this Washington Herald newspaper from October 1915 feature section:

 

Based on a nickel-potash solution, the battery could not produce chlorine gas, nor should it be unstable if doused with seawater for any reason[1].  Lighter, stronger, it could potentially allow submarines to maneuver at up to a sixty-degree pitch, allowing for faster, tighter, maneuvering.  Even more importantly, it could be charged within one hour, allowing submarines to remain hidden longer in enemy waters.[2] With WWI already in full swing, and the US possibly heading to war, the possibility for greater flexibility and safety combined, was enticing, even if the Edison battery was nearly three times as expensive as the current lead-acid batteries.

By this time, the E-2, the selected test submarine, already had two 400-cell Edison batteries installed,[3]  and was undergoing dock-side tests, charging and discharging her batteries under carefully controlled conditions.  [4]

Interestingly enough, the E-2 had already experienced battery failure with her old led-acid batteries. In September 1914, the E-2 was fifty feet underwater when, unbeknownst to the crew, the lead acid of the battery chewed through the battery tanks and into the seawater ballast tanks. Ensign Edward Gillam, E-2’s Commanding Officer, detected the feared chlorine gas leaking from the battery compartment, and drove the sub to the surface, using her pumps, rather than blowing the ballast tanks (the chlorine gas could have released inside in a cloud if he had, killing his crew).[5]  The crew managed to venting the gas but the brief exposure to the gas still injured and incapacitated nearly every one of the nineteen hands aboard[6], forcing the submarine to be towed back to port.  (Later tests would show the acid had deeply pitted the entire battery tank, forcing all D and E class subs to port to replace and double-line their battery tanks.) Gillam’s lungs, however, were badly scarred, would need a year to recover, and a new CO, Charles “Savvy” Cooke, was chosen to replace him.[7]

On December 7, 1915, the E-2 made her maiden voyage with the batteries.  The initial test was successful: the batteries “produced better speed on less fuel.”[8] The experiments also proved that the Edison battery generated “nearly double the ordinary amount of hydrogen during the process of charging, but on discharge or while lying idle, gives off much less…observers aboard…reported that while in operation not enough gas was produced to be dangerous.”[9]

But Savvy wasn’t comfortable with the amount of hydrogen gas the batteries produced.  Dangerous as chlorine gas was, you could smell it, and react, hopefully in time.  Hydrogen gas is odorless, and could build up with no one knowing.  He requested the Navy’s Bureau of Steam Engineering install hydrogen gas measuring devices in the E-2 as a safety feature.  And was denied.  He suggested installing individual voltage meters for all 800 battery cells to see which ones produced hydrogen gas under certain conditions.  And was turned down. By both the Navy and the Edison Company.  (Hutchinson said they would increase the chances of a short circuit).[10]

More tests would be needed, but the early results were encouraging enough that the Edison Battery would be installed on one of the newest boats, the L-8[11], under construction in Portsmouth.  E-2, along with three other submarines, entered Brooklyn Navy Yard on December 30, 1915.  As a standard safety precaution, all four submarines were stripped of their torpedoes and drained of all fuel, and they were each about fifty feet away from her closest neighbor.

On Saturday morning, January 15, several civilian and Naval personnel went inside the E-2, down to the battery compartment.  New canvas pipes and fans had recently been installed to see if the new ventilation would cool the batteries uniformly, and so, that day, the men were measuring the voltage output and temperature of the batteries over a complete discharge, followed by a seven hour charge.[12]  For this first part at least, no one was expecting any hydrogen gas build up, though the fans and vent pipes were kept running as safety protocols demanded.  At least five men, two Navy sailors and three civilian contractors, were inside the after battery compartment, and another ten worked throughout the vessel on multiple projects.

At 1:16 pm,[13] there was a devastating explosion deep within the E-2. One man, standing the deck hatch, was blown twenty feet into the air, before landing on the drydock floor, thankfully with only minor injuries.  The ladder he had been standing on was also blown sky-high, finally landing 150 feet away.

E-2 roared, the sound of the explosion rumbling and bouncing around the confined space.  Within the battery compartment, four men, Roy Seaber of Cincinnatti, James Peck, civilian from Brooklyn, John Shultz, civilian from Brooklyn, and Joseph Logan, Civilian from Brooklyn, lay dead, and the man in charge of the discharging procedure, Chief Electrician’s Mate LL Mills, was badly injured.  Another nine men lay too injured to move, forced to breathe in the searing gas fumes which now suffocated through the submarine.[14]

From the outside, the E-2 looked was perfectly fine.  The hull designed to withstand the ocean’s pressures from the outside had contained the explosion within, though her internal space was “badly shattered.”[15]  Then the rescuers coming from the dry dock discovered a new twist: the watertight hull trapped the gasses inside the sub, forcing would-be rescuers, led by E-2’s Savvy, to don diving helmets while other men tried to pump pressuriezed air into the E-2, forcing the gas out.

Ambulances and medical personnel were on hand when the first of the injured men were hauled out to the open air.  Many were badly burned.  When the bodies of the men near the battery compartment were finally retrieved, they spoke of the severity of the explosion: all were badly burned, one was missing an appendage, and another was crushed.

Within hours, reporters were clamoring for the reason why. The navy offered one initial suggestion: that the hydrogen gas that the batteries built up when charged, had somehow been ignited by a spark.  However “It is too early to state definitely the cause of the explosion,” Said acting Secretary of the Navy, (and future president) Franklin Roosevelt.[16]  But the batteries, as it turned out, had been discharging, and shouldn’t have been throwing off enough hydrogen to spark anything, much less a massive explosion.  .  The only two other immediate theories were the explosion was caused by the diesel-oil engines…but no diesel had been onboard and the engines were intact…or an air flask nearby had exploded…but an explosion of one of those should have blasted metal shards throughout the battery compartment, which hadn’t happened.[17]  Another option, intentional sabotage, was ruled out by January 17.[18]

A Naval inquiry would be required, and the coroner of Brooklyn also announced and inquiry on behalf of the three dead civilians.

Despite not being on board the E-2 at the time of the explosion, and leading the rescue effort, as CO, Savvy’s career was potentially on the line.  He needed a defense counsel, and chose a fellow submarine officer: Chester Nimitz, future WWII Commander of the Pacific Fleet.

Now Hutchinson and Savvy were at polar ends, each believing the other’s people or devices had to be the cause of the explosion.  During the inquiry and the many press releases surrounding it, many conflicting statements were made:

  • Hutchinson, inspecting the E-2 the day after the explosion, stated that the batteries were intact and undamaged, proving that the explosion, even if it happened in the same vicinity, had to have come from somewhere else.[19]
  • Naval Lt. C.S. McDowell, stated that he too had inspected the remains of the E-2, and said the after compartment of the Edison batteries “were completely ‘blown up’ [and] the forward batteries also damaged.”[20]
  • Savvy revealed his requests for safety devices, only to be turned down. [21]
  • Hutchinson announced that the Edison battery was safe, and as proof, it was currently in use in three “non-German” European submarines, currently waging war in Europe.  One of those unnamed subs had sunk seventeen ships thus far.  This surprised many people, as it was assumed the US Navy would have exclusive rights to the Edison Battery if it passed its tests.[22]

While the investigation continued, a fifth man succumbed to his injuries.  But some of the others, crucially, Chief Electrician’s Make Lewis Miles, were slowly improving.

As soon as the survivors were stable, they started to give testimony.  Five men were able to speak, though from reports, they had to speak through a head-full of bandages, only their eyes and mouths visible.[23]

They were adamant about several points, however

1.)     No one was smoking[24]

2.)     There was a blinding flash, then they were all insensible[25]

3.)     There was no smoking or sparking wires on the E-2 on January 15[26]

The two critical testimonies came from Raymond Otto, a second class electrician’s mate from E-2’s crew, and Chief Electrician Lewis Mills, who had been in the battery compartment when the explosion happened.  Otto, who had been partially blasted through E-2’s hatch, and burned his legs, was able to testify around January 19, but Miles, forever confined to a bed, and whose voice permanently restrained to a whisper, couldn’t testify until early February.[27]

Both men, however, recalled the same unusual thing: four of the Edison Battery cells had depleted their charge, and were bubbling moments before the explosion.  The bubbling was hydrogen gas, being produced as the cells, depleted of their charge, had begun to recharge ahead of the others.  If they had produced enough hydrogen gas to stay ahead of the new ventilation system, a random spark (though from what, no one ever saw) could have, may have, caused the explosion.

By the end of January, the civilian coroner’s jury found that the cause of the civilians’ death was an “explosion of gases.” However, they also “were unable to determine the cause of the gases” [28] Despite testimony from naval and civilian experts, the civilian jury was not able to find any new conclusions regarding what gasses or sparks may or may not have sparked the explosion.

In the end, on the 19th of February 1916, the Naval Court of Inquiry wrapped up, though the results were strangely, not made public after conferences with officers of the Navy and Secretary of the Navy, Josephus  Daniels.[29]  The official conclusion did, however, absolve Charles “Savvy” Cooke from any blame.[30]

The press reported that the “court reached substantially the same decision as the board of investigation appointed by the navy commandant immediately after the accident” most likely buildup of hydrogen gas and a stray spark, though the “spark’s” origin was never discovered.[31]

The Navy decided to pull the Edison batteries from the under-construction L-8 in Portsmouth, but turn the E-2 into a floating laboratory, testing the Edison battery further.

They also pulled Savvy from his boat, reassigning him as an engineering officer on the Receiving Ship USS Salem in Boston.[32]  It was a step down in career, though the worst, for Savvy, was the sleepless nights wondering if he could have saved his crew, somehow.  He wouldn’t be given command of another submarine until after WWI…and then he would, once again, be in the news for a submarine incident that almost, again, took the lives of him and his crew.  Quick thinking on Savvy’s part, however would save them.  Just watch.

 

The E-2 would recover, and spend the next two years near the Navy Yards, testing the Edison and Ironside batteries thoroughly (some naval records state that as the Edison batteries themselves survived the 15 January explosion (one count that suggests the batteries were nto the cause of the explosion itself) they had to be tested cell by cell, to find the problem.  None was ever found.).  The Edison batteries were eventually passed over.  USS E-2 was recommissioned in 1918, and served in WWI running anti-U-boat patrols off Cape Hatteras.  None the worse for WWI, and having completed longer patrols than ever before, E-2 was decommissioned on 20 October 1921, and sold for scrap on 19 April 1922.

RIP USS F-4 and her crew

Lost Subs | Posted by Rebekah
Mar 25 2010

Today marks the 95th anniversary of the very first submarine lost in the modern US Navy’s Submarine Force.

The USS F-4 was one of 4 sisters of the F Class submarines.  Built in Seattle, she was the first submarine named “Skate”, but her name was officially changed to F-4 before her launch.  She had only two short years of service on the Pacific Coast, before 25 March, 1915.

The USS F-4

The fours sisters were the very first naval vessels home ported at Pearl Harbor, Hawaii, and were towed there in 1914 by destroyers.  (they were already becoming too large to be ferried aboard Submarine Tenders as seen in the Tender Post.)But because Pearl Harbor was still being made suitable as a naval base, the submarines were moored next to their tender Alert in nearby Honolulu Harbor.

The USS Alert with her nest of submarines, ca. 1914, Long Beach, CA. The outermost submarine is the F-4.

On the morning of March 25, 1915, the F-1, F-2, and F-4 left Pearl Harbor on routine diving exercises.  The hazard pay of “a dollar a dive day” had just been instituted by the Federal Government, giving every man of a submarine crew an extra dollar of pay for every day a submarine dove successfully, up to $15/month (the approximate equivalent of $22/dive or  an extra $330/month,) with an additional$60 $(1320) to their families if they didn’t come back.  Submarine commanders, to keep their crews in practice and happy,  frequently scheduled diving practice!

But that morning, the F-4 didn’t return.

After an hour of no one seeing or hearing from here, a speedboat was sent out to see if she could be spotted on the surface.  A short time later, her sister, the F-3 was sent to cruise submerged in the general area the F-4 was last seen, sounding her bell, and listening for F-4’s reply.  Nothing.  Soon, their tender Alert and several more speedboats where scattering, looking for any trace of the missing sub, and a wire was sent to Pearl informing then that F-4 was overdue.

In the afternoon they found it: an oil slick and air bubbles on the surface of the water.  F-4 was probably sunk and slowly leaking, but was the crew still alive?  Rescue efforts were quickly stalled when she was found in 300 feet of water.  No diver had ever been deeper than 60 feet before.  They tried to drag the F-4 to nearby shallow water, then dredging her, but she was stuck fast and couldn’t be moved.  In 72 hours, rescue attempts were abandoned, but the Navy decided to salvage the F-4 if they could to discover what happened to her, and, since it was peacetime and the sub most likely went down due to mechanical malfunction, how they could prevent it from happening again.

But no ship had ever been salvaged from such a deep depth.  And if the Navy was going to be able to understand what happened, they had to raise her with a minimum of damage.  Lt. Cmdr.  Julius Furer was assigned the task of bringing F-4 up and he quickly searched out the most recent technology he could.

The first thing he heard of was a new kind of dive technique where divers paused at pre-determined points during an ascent and waited, which seemed to prevent the “bends”, a painful side-effect of deep diving that often caused death.  (Today, we know that the bends are caused by gases which naturally occurs in the body and dissolves in the blood.  At high pressures, like the depths of the ocean, more gasses dissolve in the blood and if a person ascends or depressurizes too quickly, the gasses form bubbles that can cause intense pain in the joints through paralysis and death.  Stopping and resting at pre-determined depths allows these gases to dissapate naturally.)  There were a group of experimental divers at the New York Navy Yard that Furer requested to come and help with the salvage.

It took nearly a month to get the first one there, and he dove to the F-4 to find her laying on her side, apparently undamaged.  The F-4 couldn’t be raised all at once, but the plan was for the divers to place tow cables under the bow and stern and lift and move her to shallow enough waters to fully salvage her.

It was nerve wracking work, and when one diver got tangled in the cables on April 17 and another diver, F.W. Crilly had to pull him to surface quickly, earning them a 20-hour trip in a decompression chamber, Crilly received the Medal of Honor, the highest award the US can bestow.

Eventually, Furer invented a new salvage technique:  Pontoons attached to cables were filled with water and sunk to either side of the wreck.  Once they were attached to the wreck with cables slung under the hull, air was pumped into the pontoons, forcing the water out, and the pontoons to the surface cradling the F-4.  This also allowed for more than two supporting cables, more evenly distributing the weight of the submarine and keeping the cables from breaking.  This worked, and on August 30, five months after F-4 went down, she was towed under the pontoons to a dry-dock.

An altered photograph showing how the USS F-4 was eventually raised and taken back to Pearl Harbor. This method of deep sea salvage would be used again in 1939 when the USS Squalus sank.

Only four of the 21 crewmen could be identified, and the other 17, including her CO, were buried in four coffins in a mass grave in Arlington (the story of the grave and her marker is also interesting and will have to wait.)

What the investigation revealed is that some of the rivets in the hull had corroded, allowing seawater into the battery compartment, releasing chlorine gas.  Captain Ede tried to blow the ballast tanks and steer F-4 into shallow water, but the engines overheated and quit, and F-4 descended past safe depths.  The intense pressure caused the hull to implode and drown her brave crew.  They were gone before anyone knew to look for them.

Here you can see the implosion of F-4's hull that was discovered once the dry dock was pumped free of water.

The F-4 herself was buried at Pearl Harbor, where she has remained ever since.  Her sisters were towed back to the mainland, and overhauled to fix the rivets, battery compartments, engines, propellors, and  the hundreds of little things that cost 21 men their lives.
