Operation Crossroads

Many who served on Saratoga witness her death by A-bomb

Fleet of Navy planes drones requiem for famed sister ship of Lexington
By W. H. Shippen Jr., Star staff correspondent

ABOARD USS APPALACHIAN, in Bikini Lagoon – When the stubborn old aircraft carrier Saratoga went down to meet Davy Jones, she left behind one whale of an argument kicked up by the world’s first underwater atomic bomb. The debate is now roaring across the fleet as fast as the speed of sound and with plenty of noise.

Nothing P. T. Barnum in his heyday or Hollywood at its wildest ever dreamed up could equal the spectacle which had as its aftermath the nosedive of the faithful old battleship Arkansas and the fatal wounding of the Saratoga, last of the twin “fighting sisters.”

Through the long tropical afternoon and well into this evening, those not arguing, beating typewriters or talking into microphones watched the “Sara” settle and pulled for her in her last agony. The air over her and the water about her too hot for close approach by observation planes or emergency salvage crews, the gallant old flattop fought her last battle alone although there are hundreds of men in this fleet who helped sail her through all kinds of brawls.

Around 3 p.m. the “Sara” started under by the stern, and as she slanted toward her last mission, we could see her worn flight deck glinting in the sun. She went down slowly with the grave reluctance befitting a fighting lady. Her flight deck astern was awash for a time and then disappeared beneath the water. Her bow slowly tilted toward us and came temporarily to rest as the stern reached bottom some 30 fathoms down.

Then air pressure began to blow holes in her bow and water spouts gushed upward as the 990-foot-long carrier breathed her last.

A fleet of Navy planes droned a requiem above and men stood at attention throughout the observation fleet, some with eyes not too dry, as the “Sara” passed from view – a fighting lady from a long and honorable line of Saratoga, whose twin sister, the Lexington, met her death in more tragic circumstances under a storm of Japanese dive bombers and torpedo planes in the Coral Sea.

Things happened so fast and frequently this morning that we all wanted to be several places at once with more than two eyes and ears and a half dozen pencils. We would have liked to be in the air, but those boys were farther from the blast than our own nine and a half miles; or on the bridge, or down in the wardroom hanging over television screens relaying motion pictures from Bikini beach.

Horizon flawless

We wanted to be on the flagship with King Juda, watching his beloved island under a cloud of thunder, or even where we were. From our ship the flawless horizon studded with familiar target vessels and lined with the bright beaches, palms and observation towers on the atoll presented a worthy setting for the cosmic show.

At me detonation blast, sailors who have seen and heard about everything broke into exclamations of admiration, pain and pleasure. Profane, perhaps, but none the less expressive. So much happened in the first seconds that I can’t be too sure of what I saw. But this is how it seemed to an observer who tried later to check his facts:

First a white hemisphere containing a fiery core pushed up from the sea. It expanded like a bubble and dispersed with the speed of sound, which flew off into the air in some sort of shock wave, I presume.

Then up spouted a dark and turbulent mushroom. From its head three or four air waves like expanding doughnuts flashed off into the sky, perhaps carrying away debris, gas or condensing water from the expansion point.

Next the tortured lagoon threw up a dazzling white column of water that seemed to boil and effervesce. Over and over in it tossed a dark object like a chunk torn from one of the guinea pig ships. This column rose a mile or more and seemed at least half a mile wide across its base. It probably contained several million tons of water, vaporized, bubbling or moving in great globules.

The column was capped to about a minute by a dark purple plume of gas and vapor that rose at least another mile as the water began to cascade down from the white spout.

As the water descended, a mighty wave was born at its base. It grew as something in a nightmare, forming a frothy white circle around the dwindling column. I think this was the momentary 100-foot tidal wave predicted by oceanographers.

The whole thing seemed to tower up and rush at us and I think I would be justified in saying it caused at least a moment of fear to all who watched from the surface at close range. But the wave swiftly dissipated itself, taking the form of whitecaps rolling at us down an open channel entrance.

Waves which hit Bikini beach, according to men on the television screens, were no more than seven to 10 feet and failed to inundate the atoll. It seems likely our recreation center over there, the “Wednesday Evening Marching and Chowder Society,” is undamaged, although the waves floated off a number of beached landing craft.

In a matter of five minutes, a mist was forming where the high wave had been. It spread and started to obscure the outer fringes of the target fleet not blotted out by the central explosion. The gas plume began to drift away, and in several minutes the mist started lifting its thick veil from the manless fleet.

For at least an hour and a half the poisonous mist or haze was visible as the steady trades shoved it downwind and finally erased it from our view. Weathermen surely hit both bomb test dates on the button.

Watched death throes

Meanwhile, the Appalachian and other observation ships were moving toward the lagoon, protected by the reef from the contaminating water and by constant wind from the poison aloft. By 10 a.m., from a range of four miles, we were watching the Saratoga in her death throes, and the Arkansas had gone down in 30 fathoms behind the atomic curtain.

Several of us had gone aboard the Arkansas at anchor in the lagoon a fortnight ago, where we were received by her skipper, Capt. Wade De Weese. Oldest battleship in the fleet, she had received only slight damage from the air blast, though her compartmentation was far less sturdy than that of modern battleships.

On the Appalachian this morning the shock wave, transmitted through the water, hit the ship a few seconds after the explosion. Most below decks veterans described it as like the sensation produced by a fairly near miss by an air bomb.

Topside, we got almost none of this shock, but our eardrums took quite a wallop about a minute after the explosion. I was so absorbed with the spectacle I had completely forgotten this highly audible reaction until it rolled across the ocean, lifting me a couple of feet out of my favorite deck chair. It was quite some bang, much stronger than the sound of distant thunder which followed the air test.

As pro and con discussion goes on here as to the effectiveness of atomic weapons against a floating, dispersed military city of steel, some are inclined to lose sight of Adm. Blandy’s oft-repeated theme: The tests were calculated to produce maximum data rather than maximum damage.

We are how proceeding into the lagoon as far as the Geiger counter-monitors will permit, to find out among other things what weird looking object Is draped over a floating drydock. Maybe it’s a missing LST.

Three on target transport spend anxious moments

ABOARD THE USS MOUNT MCKINLEY (AP) – Three men aboard the target transport Gasconade in Bikini Lagoon presumably spent an anxious time early this morning.

Lookouts aboard the Mount McKinley noticed, as the flagship steamed toward the exit of the lagoon, a flag hoist of bunting flying from the Gasconade indicating men still were aboard, although they were supposed to have left hours before.

A tug was ordered to investigate. Watchers from the flagship could see men standing at the rail. They apparently awakened, realized they were still aboard the target ship with the explosion hour drawing nigh and had no way of radio communications.

Therefore, they did the only thing left – flew the bunting, knowing it would attract attention.

At 5:55 a.m., only a few minutes before the picket boat picked up the weapon ship party, the tug took the three aboard and hustled toward safety.

Vice Adm. W. H. P. Blandy watched the whole procedure through binoculars.

Editorial: Russia and Bikini

A few hours before the news came in from Bikini yesterday, the news from New York was that Russia had decided – perhaps not irrevocably – that horse-and-drosky thinking would be good enough for the atomic age. From the standpoint of international collective security, nothing could be more depressing, nor could anything better illustrate the essentially backward and reactionary nature of the much-touted “great and progressive” Soviet experiment.

The reports from Bikini are still somewhat fragmentary, but they leave little room for doubt that the underwater atomic explosion was even more deadly than the devastating midair burst of a few weeks ago. Clearly, unquestionably, the A bomb is so awesomely destructive in relation to sea power that revolutionary changes have become mandatory in the makeup, the construction, the tactics and strategy of the world’s navies. As for cities, industrial concentrations, land armies and the like, we already have the detailed story of Hiroshima and Nagasaki to demonstrate beyond the slightest margin of debate that the problem of security among nations has been profoundly transformed and that unless this terrible new power is subjected to effective international control, civilization will be inviting its own suicide.

Yet, despite all this, here we have Andrei A. Gromyko in New York saying to the world, in effect, that Russia chooses to live according to the standards of a dead age and to cope with the atom much as an ostrich would, burying its head deep in the sand and feeling safe and secure in a blissful state of seeing nothing, hearing nothing and understanding nothing. This, at any rate, would seem to be the chief implication of Mr. Gromyko’s rejection of the American plan for a system of international atomic control with teeth in it, unhampered by the veto of any power.

It is a revealing measure of Moscow’s obsolete thinking that no other nation of consequence is opposed to the American plan. On the contrary, in its essentials, it is universally favored, the Soviet Union alone excepted. Hiroshima, Nagasaki, the two tests at Bikini, the sharp and urgent warnings of all the statesmen and scientists who know the true meaning of the atom – none of these things has convinced Russia. There it stands, the least forward-looking of the world’s great nations. Possibly, when it comes to realize how uniquely backward it is, it will begin to change its mind and act as it must act if the atomic age is not to degenerate into incomparably the most dangerous armaments race since the beginning of time.

Bikini blast sinks 11 ships

Undersea explosion lifts million tons of water 9000 feet in air
By Joseph L. Myler, United Press staff writer

OFF BIKINI ATOLL (UP) – Vice Adm. W. H. P. Blandy moved his major observation ships late tonight into the mouth of Bikini Lagoon to whose bottom today’s underwater explosion of an atom bomb sent 11 ships from the guinea pig fleet.

The observation ships dropped anchor within a few hundred yards of the deadly, radioactive water which still concealed the details of the underwater test of an atom bomb against naval power.

History’s fifth atomic bomb, which a sailor named “Helen of Bikini,” was exploded at 8:35 a.m. today (5:35 p.m. Wednesday EDT).

“Helen” was detonated by radio impulse from the scientific ship Cumberland Sound.

A peach-colored geyser of water and steam erupted from the center of the lagoon, roaring 9,000 feet into the cloud-specked sky in a few minutes.

It hung there almost motionless for some 20 seconds. Then, like a thousand cloudbursts rolled into one, it plunged downward, dropping a million tons of grey-green water and bits of the wreckage of the LSM 60 upon the anchored target fleet with terrific impact.

Cloud spreads

A giant cloud of radioactive spray, fog and spume spread slowly over the lagoon.

The cloud was still visible at sunset, drifting slowly to the north.

Early reports showed:

SUNK: Battleship Arkansas, aircraft carrier Saratoga, cement yard oiler YO-160, two landing craft (tank), and the craft from which the bomb was suspended when it exploded, the landing ship (medium) 60.

PROBABLY SUNK: Five submarines, the Pilotfish, Apogon, Skipjack, Sea Raven and Dentuda.

BADLY DAMAGED: Battleships New York and Nagato, destroyer Hughes, attack transport Fallon. The deck of the Hughes was only four feet above the water line.

Adm. Blandy said late tonight he was not convinced that the submarines sank “because of any structural damage from the bomb burst.” He said air spotters indicated the submarines’ buoys had been disarranged by the blast and that it is possible the air hoses had been cut with the result that their ballast tanks were flooded.

Fifteen hours after the bomb burst, Adm. Blandy moved more than 20 of his observer ships inside the entrance of the lagoon and anchored them off the southeast corner of Bikini Atoll.

Test water

Radio-controlled monitor boats plied the still dangerous water beyond, keeping the command ship constantly formed of the lethal quality of the contaminated water.

Adm. Blandy announced that instrumentation crews went ashore on Bikini and Envu Islands this afternoon to pick up data “vital to the task force.” He did not reveal the nature of this data. He estimated it would be three to five days before task force ships would be able to visit the target center.

Four LCTs and one LST which had been beached on the shore of Bikini Island were washed several hundred yards out into the lagoon and an LCM on the beach appeared awash.

Tries to save Saratoga

Their fate, and the fate of other ships in the target fleet which almost certainly also were damaged, depended on how soon salvage crews would be able to re-enter the lagoon.

Adm. Blandy tried desperately to save the Saratoga. He sent two tugs in with orders to beach her, but they had to turn back. The grand “Old Lady,” survivor of two torpedoings during the war, rolled over and sank in a cloud of steam seven hours and 33 minutes after the underwater shockwave crushed her starboard side.

The 29,000-ton Arkansas – oldest battleship in the Navy – apparently went down within a matter of minutes. She and the “Sara” were about 800 yards from the bomb when it went off – closest of any of the 87 target vessels.

Drone boats enter

Either vaporized or blown to bits were a concrete oil barge, a LST and the LSM 60 from which the lethal weapon was suspended about 25 feet below the surface of the lagoon.

Yellow drone patrol boats, controlled by radio from ships and planes, were sent unmanned into the lagoon three hours after the blast to pick up samples of radioactive water and air.

An unidentified destroyer ventured to within half a mile of the target center several hours after the explosion, but was seen to suddenly reverse her course and speed out to sea again. Her Geiger counters apparently had indicated the radioactivity was too deadly.

Air blast stronger

The job of boarding parties and salvage crews was made more hazardous by the fact that the bomb subjected most of the ships to showers of radioactive rain.

It upset the predictions of scientists in several respects:

  • It produced a thinner and less spire-like water spout than anticipated.

  • It produced a stronger air blast, indicating that a smaller proportion of energy was retained in the water than scientists had expected.

  • It sank fewer ships immediately. Unofficial guesses were that possibly as many as a dozen ships would go down under the initial force of the explosion.

Calls test success

But from the flag bridge of his flagship, the Mt. McKinley, Adm. Blandy broadcast a message a few hours after the blast stating that it had been a complete success. Not a man of the 40,000 who participated in the operation was injured, Adm. Blandy said.

Almost overshadowing the awesome sight of the bursting bomb was the sinking of the venerable old Saratoga.

The 39,000-ton carrier, built on the hull of a super-battle cruiser, had extraordinarily good compartmentation. She had survived two torpedoings and one Kamikaze attack. But the A-bomb was too much for her.

United Press writer Frank H. Bartholomew reported from the Appalachian that the Sara began to sink by the stern at 4:30 p.m. The aft edge of her flight deck went under water and oil bubbled up amidships.

Stern settles

“Suddenly her bow rose high in the air and the large figure ‘3’ painted on her flight deck came into view. Cascades of aerated water bubbled beneath her how. Her stern settled to the bottom of the lagoon, the tip of her mast extended at an angle,” Mr. Bartholomew said.

“Then she quietly died. Down under went the bow. The mast straightened out and the great ‘Sara’ was in her grave.”

“Test Baker” began unwinding at dawn.

The day broke bright and clear.

The target vessels in the distance bobbed like boats on a rippled bomb. Aboard the LSM 60, the bomb placement crew worked swiftly to lower the “big boy.”

Three rescued

Someone noticed full bunting and three undershirts still flying on the target transport Gasconade. A tug rushed to the ship and took off an officer and two enlisted men. It was only two hours and 52 minutes before the blast.

The LSM 60 weaponeers, accompanied by Rear Adm W. S. Parsons, sped out of the lagoon at 6 a.m. The only life left aboard ship was the animals placed there to test the radioactivity.

The chosen “trigger-man,” Dr. Marshall Holloway, and a staff of atomic scientists including Roger Warner and Herbert J. Hall, a Massachusetts Institute of Technology radar expert, had slept aboard the landing ship, above the bomb.

Presses button

Dr. Holloway pressed a button at 8:35.

Shock waves, traveling at an estimated 5,000 feet a second, jarred the observer ships before the tremendous roar split the air.

An awesome column of water, an estimated 2,136 feet across at its base, rose out of the lagoon, obscuring the target ships. The peach-colored bulge looked like an inverted derby hat.

From a B-29 above the target, Lt. Cmdr. William Wood reported that the spray and steam shot above his plane at 7,000 feet, and rested lazily in the air at around 8,000 feet. A great cloud hid the fleet from above.

Waves roll out

Then the dome of water crashed down.

Heavy, oversized waves rolled outward in a circular motion from the center of the explosion, Adm. Blandy said these waves were seven to 10 feet high when they smashed against the coral beaches of deserted Bikini Island, three and a half miles away. Palm trees on the shore were splintered.

Hours later the lagoon was covered by a green, scummish coat indicating that a huge hole had been gouged out of the coral bottom of the sea.

Sailors’ tears say adieu to gallant carrier ‘Sara’

By William F. Tyree, United Press staff writer

OFF BIKINI ATOLL (UP) – The gallant Saratoga, which survived hundreds of Jap assaults in World War II sank today – the victim of “Helen of Bikini,” the world’s fifth atom bomb.

When the underwater bomb went off this morning with the fury of thousands of tornadoes, the thick steel plates of the big carrier were sprung. The ship was mortally wounded.

“Helen” did what her plutonium-filled sister, Gilda, bomb No. 4, which was dropped aerially over Bikini last July 1, failed to do – “sink the Sara.”

The titanic upheaval of water that “Helen” exploded with awesome might tore through the steel plates which protected the “Sara”, against torpedoes. The gallant old ship did her best to stay afloat.

Dies quietly

But for the first time in her long, fight-filled career, the best wasn’t good enough.

Seven hours and 33 minutes from the moment when the atom bomb crushed her starboard side, the Saratoga sank. The old fugitive from the scrap heap died quietly.

“Hail and farewell,” said the loudspeaker of the press ship, the Appalachian, as some sailors wept. One blurted: “Dammit. Why do we have to lose her?”

The Sara’s big numeral “3” on the forward edge of her flight deck was the last thing visible in the gleaming afternoon sun. The “3” was for her seniority as a carrier in the Navy. Only the Langley and the Lexington were built before her. Both of them are gone.

Hundreds to mourn ship

Shortly before 4 p.m., Bikini time, the after-flight deck of the Saratoga eased under the surface. A minute later, water went up t her battered island.

Within 12 minutes between the disappearance of the flight deck and the mast, the Saratoga’s stern apparently rested on the bottom of the lagoon. She fought the onrushing waters to the finish.

Hundreds of sailors will mourn the Sara’s passing. There wasn’t another ship in the fleet quite like the Saratoga – in heart or in looks.

Her huge, single-stacked island had a peculiar grace to it, poking up into the sky and towering above her 909-foot flight deck. That deck, 105 feet wide and just barely able to squeeze through the Panama Canal, had sent angry Navy fighter and bomber planes against the Japs from Guadalcanal to Tokyo.

Sister ships sunk

Few records show for sure just how many enemy planes her fighters shot down during her days of battle against the Nips. That total would run well into the hundreds, if not thousands. Thousands of Japs, for sure, joined their ancestors at the invitation of the Sara’s planes.

At one time in the war – after her sister ship, the old Lexington, was sunk at Midway and her cousins, the Wasp and the Hornet, were lost in the Solomons – she was the only first-line U.S. carrier in the Pacific.

Fighting wasn’t her only job. Before the war, she once tied up at Tacoma, Washington, to supply emergency power to that city from her huge generators. After the war, she was a “Magic Carpet” that brought thousands of servicemen home.

But fighting was the job she loved best. She itched for that task from the time she was commissioned in 1927. A flier named Marc A. Mitscher, who later cut quite a name for himself, made the first post-commissioning landing on her. December 7, 1941, found her at San Diego just sailing for Pearl Harbor with a load of planes.

Her scoreboard on the island carried stars for eight major Pacific campaigns and bars for 23 “assignments.”

Those campaigns and assignments are a recapitulation of the progress of the war against Japan: Guadalcanal landings; the battle of Guadalcanal; the Eastern Solomons operation; landings in Bougainville, the Gilberts and the Marshalls; the Sabang raid; the attack on Soerabaja, and finally the attacks on Japan.

Six times the enemy reported the Sara as “sunk.” Six times she showed up still very much alive.

Twice she was hit by torpedoes, but her big blisters saved her from any serious damage.

Toll of ships shows clearly in atom blast

Arkansas goes down in 15 minutes
By S. Burton Heath, Scripps-Howard staff writer

OFF BIKINI REEF – What appears to stand out about the second atom bomb test is the fact that the toll of ships is being counted faster than in the case of the July 1 explosion.
though 1 may not be known

Although it may not be known for some time how much actual damage was done by the underwater bomb to the target fleet, there won’t be any real doubt thus time, as there was last time, about the terrible might of the bomb.

From a closer vantage point this time we saw enough to know that “Helen of Bikini,” as the bomb was named, was a full-strength bomb and that it released a power beyond adequate description.

Arkansas sinks quickly

The question that the Joint Chiefs of Staff posed to Adm. W. H. P. Blandy, task force commander, was: “What can a single atomic bomb of the smallest size that can be made do to warships of various types at various distances?”

Before the smoke had cleared, we had one impressive answer: It can sink a 26,000-ton battleship at almost a quarter of a mile distance within 15 minutes.

Then for hours we kept a death watch on one of the grandest warriors of them all – the mighty Saratoga, oldest U.S. carrier. From a distance of three miles, we watched her slowly list to the starboard and then settle by the stern. She went down less than nine hours after the blast.

Landing craft vanishes

In addition, a concrete oil barge was sunk and a landing craft from which the bomb was suspended simply disappeared, probably pulverized by the blast.

This bomb was designed to smash, crush, twist and warp underwater hulls. Ships may remain afloat for hours while water slowly entered the exposed compartment. This eventually may break bulkheads and sand the ship to the bottom.

Until the sinking, capsizing, settling or listing is apparent, the only way of knowing about the damage would be to put the vessel in drydock or by sending down divers, which obviously is impossible, at least until radioactivity clears.

Therefore you shouldn’t draw any inferences presently from the small number of ships sunk. We here at the scene aren’t.

Monster lashing in agony, that’s atom blast geyser

Column of water hurtles into air at speed for 2000 feet per second over Bikini Lagoon
By Daniel Wilkes, Science Service staff writer

ABOARD USS APPALACHIAN OFF BIKINI (SS) – The Gates of Hell yawned briefly before me across a peaceful stretch of the Pacific and then clanged shut with the fury of a thousand monsters and steaming radioactive water.

The fifth atomic bomb had been born and died – breaking surface like a monster lashing in agony at the sea and the test ships spaced neatly in the lagoon.

That was my first reaction to the underwater explosion of an atomic bomb viewed through binoculars. A column of water in brown colors hurtled into the air at a speed of 2,000 feet per second, followed by a breaking at the top. At the bottom were much larger, great, billowing, white and beige clouds, which spread quickly at first and then more slowly, hugging the sea surface.

In a few minutes the central target area was obscured for perhaps a diameter of two miles.

The top cloud broke first into a dirty brown color, then spreading into a luminous white mass which was soon lost in nature’s clouds.

The underwater blast shook our ship slightly soon after the column appeared, followed about a minute later by blast and distant boom which rocked the vessel as though it had hit a high wave. The cloud a thousand feet high and dirty at the bottom cleared only slowly.

Within an hour the target area cleared. Nearly two hours later, the sur face cloud. diffused but still visible, moved toward the horizon as a sickly fog hugging the sea.

‘Big boom’ fails to impress king of Bikini Island

OFF BIKINI ATOLL (UP) – King Juda of Bikini was disappointed.

From the USS Mt. McKinley, Vice Adm. W. H. P. Blandy’s flagship, the king watched today’s underwater explosion of an atom bomb.

“Big Boom, too far away,” he said.

When he could get a word with officials who were more excited than he was about the bomb, King Juda asked when he and his 166 subjects could return to Bikini Island which they abandoned so the tests could be made.

King Juda, who arrived by plane from his new home on Rongerik Island and was permitted by Washington officials to stay and witness the blast, said he didn’t want to appear impatient. He just wanted a little information. If the Navy wants Bikini for next year’s deep-water explosion – he’ll wait.

“Americans my friends,” he said through his interpreter. “I will help them all I can.”

3 drone planes damaged in test

KWAJALEIN (UP) – Three of the four radio-controlled drone Flying Fortresses suffered minor damage during the underwater atomic bomb test, Col. Harvey T. Alness, commanding officer of the Army Air Forces drone unit, revealed.

In a radioed report from the drone base at Eniwetok, Col. Alness said one “Fort” was damaged in a landing accident and two others by the violence of the explosion.

All Navy aircraft returned safely, including three Navy drones, according to Rear Adm. C. A. F. Sprague, Navy air unit commander.

Several plates were blown loose and plexiglass in the tail was blown in by the blast on one Army drone which was flying at 6,000 feet almost directly overhead when the bomb exploded.

Another drone which was overhead at 16,000 feet seconds after the blast had several plates torn loose.

Bomb blasted ancient warships

Arkansas, Saratoga oldest of types
By Ron Ross, Science Service staff writer

WASHINGTON (SS) – The Navy’s answer to critics of shipbuilding in an atomic age can be that victims of Bikini are not modern American naval vessels.

With combined age of more than half-a-century, the Arkansas and Saratoga faced the atomic bomb with more age than armor. Oldest ships of their respective types in the Navy, they are not claimed to be a match for the sleek Iowa-class battleships and the huge, new Midway-class aircraft carriers.

The Arkansas carried President Taft to the Panama Canal in 1912, the year she was commissioned. In convoy duty and bombardment at Normandy, Southern France and Iwo Jima, she was the oldest American battlewagon to see action in the war.

The Saratoga was converted into an aircraft carrier after the Washington naval conference, 1921-22, and modified and repaired several times during World War II.

Deep water blast called greatest

LOS ALAMOS, New Mexico (UP) – Dr. Maurice M. Shapiro physicist and former chairman of the Association of Los Alamos Scientists, said today that the second atom bomb test at Bikini Atoll will not be an example of the maximum power of the bomb.

Dr. Shapiro explained that the most destructive elements in an A-bomb will occur when the bomb submerged far beneath the surface of the ocean.

“The second Bikini experiment… is more like a surface burst than a real underwater explosion,” he said. In yesterday’s test the bomb was set off beneath the surface, “but for an atomic bomb, a depth of 20 feet is not much different from no depth at all,” he said.


Blast not registered on seismograph

WESTON, Massachusetts (UP) – The first underwater atomic bomb explosion was not strong enough to register on the Weston College seismograph, Rev. Daniel Linehan, S.J., reported today.

The photographic record, developed a few minutes after the bomb exploded, showed no trace of the blast. Father Linehan expressed the opinion that only stations within a 1,000-foot radius of Bikini would record the shock.

Wiener Kurier (July 26, 1946)

Druckwirkung der Atombombe übertraf olle Erwartungen

Bisher sieben Schiffe als versenkt gemeldet

Bikini-Atoll (INS.) - Nach Auswertung der ersten einlaufenden Meldungen über den zweiten Atombombenversuch von den Roboter-Flugzeugen, Fernsehkameras, Beobachtungsstellen und den Meldungen der verschiedenen Meßstellen läßt sich bereits eindeutig sagen, daß das Kennzeichen der unter dem Wasserspiegel zur Explosion gebrachten Atombombe die alle Erwartungen übertreffende Druckwirkung gewesen ist.

Die 87 in der Bikini-Lagune nach einem genau festgelegten Schema aufgestellten Zielschiffe wurden allein durch den Explosionsdruck völlig aus ihrer Formation gebracht und boten den Beobachtern das Schauspiel einer in Auflösung befindlichen Flotts, die durch übermenschliche Gewalt aus der vorgesehenen Fahrt gebracht wurde.

Neben diese Erscheinung tritt als bedeutendstes Ergebnis dieses Versuches die Erkenntnis, daß durch die unmittelbare Wirkung der Atombombe und des radioaktiven Regens, der sich in Form eines dichten Vorhanges auf die Zielschiffe aus mehr als 1500 Meter Höhe ergoß, ein Zutritt von Lebewesen ohne Gefährdung der Sicherheit erst im Laufe der nächsten drei bis fünf Tage erfolgen kann. Die erzeugte Radioaktivität hätte, nach übereinstimmender Auffassung aller Gelehrten, restlose Vernichtung aller Lebewesen bedeutet.

Admiral Blandy nähert sich als erster dem Atoll

Wie nach dem ersten Versuch, führte auch diesmal Vizeadmiral Blandy sein Flaggschiff als erstes in die Nähe des Bikini-Atolls. Bereits wenige Stunden nach erfolgter Explosion drang er bis auf wenige Kilometer an den Rand der Lagune vor, um durch persönlichen Augenschein so nahe als möglich die aufgetretenen Schäden festzustellen. Das Betreten der Lagune selbst ist zunächst allen Teilnehmern verboten. Nur drei Meßtrupps wurde es zur Feststellung der radioaktiven Intensität gestattet, drei außerhalb der Lagune liegende Transporter sechs Stunden nach Durchführung des Versuches zu betreten, um ihre Beobachtungen aufnehmen zu können.

Sieben Schiffe gesunken

Soweit sich aus den Beobachtungsergebnissen der Roboterflugzeuge, Photos und persönlichen Beobachtungen ergibt, sind bisher sieben Schiffe als gesunken zu betrachten. Dazu gehören: Das bereits 34 Jahre in Dienst stehende Schlachtschiff „Arkansas“, vier Unterseeboote und zwei kleinere Schiffseinheiten.

Die „Arkansas“, ein Veteran aus zwei Weltkriegen, sank innerhalb von fünf Minuten. Der Flugzeugträger „Saratoga“ sitzt mit seinem Kiel auf dem Grunde der Lagune auf. Schäden wurden an dem Schlachtschiff „New York“, dem Zerstörer „Hughes“ und den amerikanischen Transportschiffen „Fallin“ und „Joana“ festgestellt. Das japanische Schlachtschiff „Nagato“, das bereits beim ersten Atombombenversuch Schäden erlitten hat, wurde auch diesmal hart getroffen. Einzelheiten konnten bisher noch nicht festgestellt werden.

L’Aube (July 26, 1946)

Épargnés par la première bombe atomique plusieurs gros navires ont été coulés ou gravement endommagés par la seconde

MAIS IL RESTE À TIRER LES ENSEIGNEMENTS DE BIKINI bis

D’après les nouvelles radiodiffusées en hâte, immédiatement après l’explosion, on put croire tout d’abord qu’une grande partie de la flotte avait été anéantie et l’île ravagée ; mais, trompés par le brouillard et les nuages de vapeur d’eau, les observateurs virent reparaître un à un la plupart des navires. Tout ce que l’on sait actuellement, c’est que onze bâtiments — et notamment le cuirassé Arkansas et le porte-avions Saratoga — ont été coulés et que beaucoup d’autres ont été gravement endommagés ; à savoir, les cuirassés New-York et Nagato, le torpilleur Hughes, le croiseur léger Indépendance, le croiseur lourd Pensacola et le transport Fallon.

Au nombre des navires coulés, il faut peut-être ajouter les sous-marins immergés qui, aux dires d’un correspondant de presse, reposeraient endommagés sur le fond de la lagune.

Un spectacle d’une beauté grandiose

L’explosion a été un spectacle d’une beauté grandiose beaucoup plus que terrifiante. Voici comment l’a vue l’un des observateurs qui se trouvait à bord de l’Appalachian.

Alors qu’on attendait l’explosion d’un moment à l’autre, régnait le calme le plus impressionnant. Sur une étendue de 16 kilomètres, une mer d’un bleu éclatant séparait l’Appalachian de la flotte-cible ancrée dans le lagon de Bikini. Des flocons de nuages légers couraient sur le ciel bleu.

Et soudain l’explosion déchire la sérénité de ce tableau splendide Une coupole liquide d’une blancheur défiant toute description surgit, s’élargit et s’aplatit, pour atteindre un diamètre de 800 mètres. Du sommet, jaillit ensuite un jet d’eau comme la tête d’un champignon monstrueux. Le dôme éclate en gros bouillons qui se propagent dans toutes les directions. Et le « chapeau » du champignon s’étend sur 1.600 mètres de diamètre : les scintillements des milliards de gouttelettes d’eau qui le composent lui donnent un éclat insoutenable.

Puis, des torrents d’eau retombent sur la flotte-cible, comme de gigantesques lames de couteaux. Elles ont la teinte de la nacre la plus délicate.

Les observateurs ont pu voir, mêlés à ces lames liquides et tombant avec elle, des fragments d’un navire.

Une source d’énergie inconnue disloque ensuite cette colonne dans toutes les directions et la transforme en un mur de brouillard qui s’étend avec une incroyable rapidité, oui dissimule à notre vue les navires objectifs à l’exception de quelques-uns d’entre eux, les plus éloignés du point d’explosion.

Pendant ce temps, le chapeau du champignon s’étend sans cesse et prend l’aspect d’un buisson épineux. Il atteint 2.500 mètres de hauteur environ, puis cesse de monter.

Ici se termine la féerie. Le nuage atomique prend l’aspect d’un nuage d’orage ordinaire, bien que la pluie qu’il répand puisse être qualifiée d’averse cosmique.

L’orage atomique s’éloigne ensuite, suspendu à mi-ciel comme le plus normal des orages d’été.

Connaissant ces résultats, faut-il conclure au succès ou à l’échec de l’expérience ? Les avis sont partagés : certains techniciens estiment que la preuve de l’énorme puissance destructive de la bombe est faite : d’autres se montrent déçus. Le Dr Maurice M. Shapiro, éminent physicien et ancien président de l’Association des hommes de science de Los Alamos, a déclaré que l’explosion de la bombe atomique immergée à Bikini ne permet pas de juger d’une façon décisive quels sont les effets d’un bombardement atomique sur une escale navale.

Jap battleship sinking at Bikini

OFF BIKINI ATOLL, Saturday, July 27 (UP) – The Baker Day atomic bomb may claim another capital ship fatality in addition to the 15 ships already listed as possibly sunk or badly damaged, an Operation Crossroads expert predicted today.

The 32,720-ton Jap battleship Nagato was reported listing eight degrees to starboard. The list indicted her hull had been breached and her below decks compartments were flooding gradually.

The 27-year-old ship developed a slight list after Thursday’s underwater atomic burst which sent the battleship Arkansas, the carrier Saratoga, three smaller vessels and possibly five submarines to the bottom of Bikini’s oil-slicked waters.

Dr. Ralph A. Sawyer, technical director of Joint Task Force One, believed the Nagato may sink in another 24 to 48 hours.

Editorial: Bikini No. 2

The second atom bomb within a month has been fired at the “ghost” fleet within Bikini Atoll and we still don’t know exactly what gives.

For one thing, the Navy was interested in concrete barges, recalling that concrete construction stood up best at Hiroshima. But an oil barge of that type was one of the first ships sunk in the underwater test. So – maybe – we can scratch concrete.

Then there were forecasts of possible giant waves that might spread all over the Pacific. The one that reached Bikini was about seven feet high.

There were warnings the island might be engulfed. It rode high and dry.

However, there were predictions that the underwater bomb would destroy more ships than the aerial test of July 1. Apparently, from the early returns, it did so.

As of this writing, 11 ships are reported sunk. What damage has been done to others and how many more of them may sink cannot be guessed. But apparently the damage to a great number of vessels was terrific.

The two test bombings at Bikini may not have been so all-out spectacular as some forecasters expected. But there can be no doubt in anyone’s mind that this weapon is the most destructive ever devised.

It’s to be hoped that radio-listening humans, who seem to be “disappointed” that the blasts were not more ruinous, will wait for a complete report and weigh all the evidence before they decide the atom bomb is something to scoff at.

It seems to have proved itself somewhat more than slightly devastating.
