Low-level photographs of the MRBM sites contained more bad news. Evidence abounded of activity. Fresh ruts in the mud suggested that the Soviets had been exercising the missiles overnight. Most of the sites were now camouflaged, some more effectively than others. Several missile launchers had been covered with plastic sheeting, but analysts were able to use earlier photographs to figure out what lay underneath. The photographs from Calabazar de Sagua were detailed enough to identify poles for camouflage netting. At San Cristobal, two hundred miles to the west, the ropes holding up the missile checkout tents were clearly visible.
Despite the attempts at camouflage, the photo interpreters had spotted cables leading from the missile checkout tents to generators and control panels hidden in the woods. They had found theodolite units, sophisticated optical instruments used for aligning missiles on the launch pad, at most of the sites. Fuel and oxidizer trailers were stationed nearby. Although none of the missiles was in the vertical position, most could be fired within six to eight hours, according to CIA estimates.
By comparing the photographs with data on R-12 readiness times from the technical manual supplied by Oleg Penkovsky, the analysts had concluded that four out of the six medium-range missile sites were "fully operational." The remaining two would probably be operational within a couple of days.
As he examined the photographs, Lundahl wondered how he would relay the latest intelligence information to the president. A frequent deliverer of bad news, he strove to avoid "dramatics." He was wary of anything that would create "a fear or stampede." At the same time, he knew he had to lay out the facts succinctly and conclusively, "so that the decision makers would be convinced, just as the photo interpreters were, that the crisis was entering a new phase."
The art of aerial reconnaissance went back to the Napoleonic wars. French troops used a military observation balloon in 1794 to spy on Dutch and Austrian troops at the battle of Maubeuge. During the American Civil War, a scientist named Thaddeus Lowe devised a method for telegraphing reports on Confederate troop positions in Virginia from a balloon tethered high above the Potomac River. Union gunners were able to use the information to target Confederate troops without being able to see them. By World War I, both the Germans and the British were using two-seater aerial reconnaissance planes to photograph enemy troop positions. Photo reconnaissance expanded greatly in World War II, both to identify targets and to survey the damage caused by the hugely destructive bombing raids over Germany and Japan.
Like most of his top analysts, Lundahl had served as a photo interpreter during the war, analyzing bombing data from Japan. He liked to boast that aerial photography supplied 80 to 90 percent of the usable military intelligence collected during World War II--and could perform a similar function in the Cold War. The flow of useful information shot up after President Eisenhower authorized the construction of the U-2, a revolutionary plane with equally revolutionary cameras, capable of photographing foot-long objects from seventy thousand feet. The demand for photographic expertise soon became overwhelming. In October 1962 alone, Lundahl's men were involved in more than six hundred separate photo interpretation projects, ranging from rocket testing sites in Krasnoyarsk to power plants in Shanghai to aircraft plants in Tashkent.
By the early sixties, overhead reconnaissance had spawned an array of esoteric subdisciplines, such as "tentology," "shelterology," and "cratology." Photo interpreters spent days analyzing the crates on the decks of Soviet ships heading for places like Egypt and Indonesia, measuring their precise dimensions, and guessing what might be hidden inside. In 1961, the CIA published a detailed guide to different kinds of crates, teaching its agents the difference between a MiG-15 and a MiG-21 crate. Cratology scored its greatest triumph in late September when analysts correctly deduced that a Soviet ship bound for Cuba was carrying Il-28 bombers. Since the Il-28 was known to be nuclear-capable, this discovery prompted Kennedy to agree to the crucial October 14 U-2 overflight of Cuba to investigate the Soviet arms buildup.
The analysts could infer a lot just by looking at a picture of a vessel, and studying the way it was sitting in the water. Some of the Soviet cargo ships en route to Cuba had been built in Finland and had unusually long hatches. They were intended for the lumber trade, but the photographs showed them riding suspiciously high in the water. There was an obvious explanation: rockets weighed a good deal less than solid timber.
An experienced photo interpreter could extract valuable intelligence information from seemingly unimportant details. The analysts associated baseball fields with Cuban troops, soccer fields with Soviet troops. A flower bed could provide valuable clues to the Soviet order of battle: some units used different-colored flowers to show off their regimental insignia. Large amounts of concrete frequently signaled some kind of nuclear installation. Without ever setting foot in Cuba, photo interpreters could feel its rhythms, appreciate its moods, and share vicariously in the lives of its inhabitants.
One of Lundahl's top assistants, Dino Brugioni, would later describe the elements that made Cuba so intriguing:
The hot morning sun; the afternoon rain clouds; the strange vegetation of the palm, coniferous, and deciduous trees; the tall marsh grass; the sugarcane fields in the plains; the small towns where people gathered; the large estates overlooking beautiful beaches; the thatched roofs of the peasant huts; the plush resort towns; the rich expanses of fincas, or ranches; the ubiquitous baseball diamonds; the cosmopolitan look of Havana and the sleepy and forgotten appearance of Santiago; the Sierra Maestras rising abruptly behind the coast; the small railroads leading from the sugar-processing centrals to the cane fields; the loneliness of the large prison on the Isle of Pines; the salt flats; the many boats and fishing yards; and the roads that cross and crisscross the island.
And in the center of this tropical paradise, like a strange excrescence upon the land, the Soviet missile sites.
8:19 A.M. FRIDAY, OCTOBER 26
By Friday morning, all four Soviet submarines in the Sargasso Sea had begun to pull back from their forward positions on orders from Moscow. Their mission had become very unclear. There were no longer any Soviet missile-carrying ships for them to protect: those that had not reached Cuba had turned back toward the Soviet Union. After a spirited debate in the Presidium, Khrushchev had decided against sending the Foxtrots through the narrow sea-lanes of the Turks and Caicos Islands, where they could easily be picked up by American submarine hunters. But the Soviet navy did authorize one submarine--B-36--to explore the wider Silver Bank Passage between Grand Turk and Hispaniola. It turned out to be a gross error of judgment.
B-36 was sighted by a U.S. Navy spotter plane at 8:19 a.m. eighty miles east of Grand Turk. The glistening black submarine was some three hundred feet long and twenty-five feet across, about twice the volume of a German U-boat. The number "911" in large white letters was clearly visible on its conning tower. The submarine submerged five minutes later. It was on a southerly course, headed toward Hispaniola, making about 7 knots an hour. The fact that it had been tracked and located marked a breakthrough for a new antisubmarine warfare device known as Sound Surveillance System, or SOSUS.
Hunting submarines was a classic example of technological competition and escalation. One side would invent a quieter, faster, or less visible submarine; the other side would develop a new technology to counter it. It was difficult to find a snorkeling submarine by radar, but it could be detected by sound. The sound emitted by the noisy diesel engines was magnified beneath the water, and could travel hundreds of miles, sometimes thousands of miles. Sound waves could be plotted and triangulated in much the same way that radio waves were plotted and triangulated.
By the late fifties, the United States had installed a system of hydrophones, or underwater microphones, along the entire eastern seaboard. Once the general location of an enemy submarine had been determined through SOSUS, U.S. Navy aircraft could use sonobuoys and radar to find the precise position. The problem with SOSUS was that it picked up other obje
cts, such as whales. More than eight hundred contacts had been registered with the system in the space of forty-eight hours. None of these contacts had yet resulted in a confirmed submarine sighting.
The naval facility on the tiny British island of Grand Turk--NAVFAC Grand Turk--was one of the earliest submarine listening posts. Built in 1954, the SOSUS station occupied a lonely peninsula on the northern tip of the six-mile-long island. Underwater cables linked the facility to a chain of hydrophones on the seabed. The hydrophones transformed sound waves into electrical charges that burned marks on outsize thermal paper rolls. A strong, clear line was a good indication of engine noise.
Technicians at NAVFAC Grand Turk had begun noticing the distinctive burn lines on Thursday evening. Submarine trackers reported "a reliable contact" at 10:25 p.m. and called in the patrol planes. They christened the contact "C-20," or "Charlie-20."
"Plane," shouted the watchman on the bridge of submarine B-36. "Dive!"
It took just a few seconds for the lookouts to scramble down the ladder of the conning tower. There was a loud gurgling sound as water flooded into the buoyancy tanks, expelling the air that kept the boat afloat. The submarine went into an emergency dive. Pots and plates flew in all directions in the galley.
Crew members rushed around the ship, turning valves and closing hatches. Most were dressed in shorts. Only the officer of the watch put on a blue navy jacket, for the sake of propriety. Many of the men had smeared a bright green antiseptic ointment over their bodies to alleviate the itching from thick red heat rashes, similar to hives. The stuffy air and the extraordinary heat, up to 134 degrees in parts of the ship, had taken their toll on the most hardy sailors. Everybody felt tired and weak, their brains numb with dizziness. Sweat poured off their bodies.
Lieutenant Anatoly Andreev had been keeping a diary in the form of an extended letter to his wife of twenty-five months. Even putting pen to paper was a monumental effort. Great globs of sweat dropped onto the page, smearing the ink. When he was not on duty, he lay in his bunk, surrounded by photographs of Sofia and their one-year-old daughter, Lili. They were his lifeline to a saner world, a world in which you breathed in fresh air and drank as much water as you liked and no one screamed at you for imaginary mistakes.
Everyone is thirsty. That's all anyone is talking about: thirst. How thirsty I am. It's hard to write, the paper is soaked in sweat. We all look as if we had just come out of a steambath. My fingertips are completely white, as if Lyalechka was one month old again, and I had just washed all her diapers.... The worst thing is that the commander's nerves are shot to hell. He's yelling at everyone and torturing himself. He doesn't understand that he should be saving his strength, and the men's too. Otherwise we are not going to last long. He is becoming paranoid, scared of his own shadow. He's hard to deal with. I feel sorry for him, and at the same time angry with him.
They had been at sea for nearly four weeks. B-36 had been the first of the four submarines to slip out of Gadzhievo in the dead of the night, without any lights. It had led the way across the Atlantic for the other subs. Captain Aleksei Dubivko was under orders from the Soviet navy to reach the Caicos Passage at the entrance to the Caribbean by the fourth week in October. He had to maintain an average speed of 12 knots, an extraordinarily fast pace for a diesel-electric submarine that could only do 7 or 8 knots underwater. For most of the voyage, it had been necessary to travel on the surface, using his diesel engines rather than his batteries and battling waves as high as a four-story building.
Apart from the grim conditions aboard ship, the journey had been fairly uneventful. The diesel engines were still functioning well--in contrast to Shumkov's experience in B-130, which was trailing four hundred miles behind. As far as they knew, they had managed to escape detection by the Americans until they arrived in the Sargasso Sea. The biggest drama was a crew member falling ill with appendicitis. The ship's doctor operated on him on the mess table in the wardroom. Since it was impossible to wield a scalpel accurately with the vessel pitching about on the surface, they conducted the operation fully submerged, cutting their speed to 3 knots and losing a day. The operation was successful.
Andreev kept up a steady commentary on his own state of mind and conditions on board ship in his rambling letter to his beloved Sofia. He was alternately awed by the power and beauty of the ocean and struggling with physical discomfort. "How magnificent the ocean is when it's angry. It's all white. I have seen bigger storms, but never anything more beautiful than this," he told Sofia, as the submarine headed across the Atlantic through gale-force winds. "The waves, what waves! They rise like mountain ridges, seemingly stretching on without end. Our vessel looks like a tiny bug next to them." After dusk fell, the ocean "became terrifying and menacing, and the beauty vanished. All that was left was the dismal blackness and the sensation that anything might happen at any minute."
When they reached the Sargasso, the sea turned "absolutely calm," the color of the water "something between navy blue and purple." But conditions on board ship deteriorated. The temperature in the coolest parts of the sub was at least 100 degrees. "The heat's driving us crazy. The humidity has gone way up. It's getting harder and harder to breathe.... Everyone's agreed that they would rather have frost and snowstorms." Andreev felt as if his head was about to "burst from the stuffy air." Sailors fainted from overheating. Carbon dioxide levels were dangerously high. Men who were not on duty would gather in the coolest section of the boat and "sit immobile, staring at a single spot."
There was not enough fresh water to go around, so the ration was cut to half a pint per crew member per day. Fortunately, there were plentiful supplies of a syrupy fruit compote, which the men drank for breakfast, lunch, and dinner. The temperature in the freezer rose to 46 degrees. As the officer in charge of the galley, Andreev ordered an increase in the meat ration, as the meat was all going bad. But hardly anyone felt like eating. Many crew members lost a third of their body weight. The captain accused Andreev of making the food go bad on purpose. "I have become an enemy of the people," Andreev wrote. "There was a big row and I feel very badly about it. The heat's been getting to us."
He thought constantly of his wife and child. "The first thing I do when I wake up is say good morning to you both." While standing watch, he imagined himself on the deck of a luxury passenger liner with Sofochka. "You are in a light summer dress and feel chilly. We stand with our arms around each other, admiring the beauty of the sea by night." He sent greetings to his wife via the constellation Orion, visible simultaneously in Russia and the Atlantic. He remembered Lili "sitting in the sand with her little arm raised.... And here you are, my mermaid, coming out of the water with a wonderful smile.... You are trying to get a ball away from her with a serious face." Memories of the "tiny hands" of his daughter, "her happy smile, her little nodding head across the table from me, her laughter, her caresses," helped him get through the hardest moments of the journey.
B-36 reached the approaches to the Caicos Passage on schedule, just as the crisis was coming to a head. It was then that Captain Dubivko received an urgent message from Moscow, ordering him to hold back. Instead of attempting to negotiate the forty-mile-wide channel, he was instructed to redeploy to the eastern end of the Turks and Caicos Islands, 150 miles away. This was the long way round to Cuba, but the sea channel was twice as wide. The navy chiefs evidently believed that the risks of detection were much reduced if the subs kept away from the narrow sea-lanes.
As B-36 rounded Grand Turk Island, with its secret SOSUS station, U.S. Navy patrol planes appeared overhead. The Soviet sailors could hear the sound of muffled explosions as the patrol planes dropped practice depth charges and sonobuoys in an effort to locate them. The atmosphere inside the submarine became even more tense. "We are in the enemy's lair. We try not to reveal our presence to them, but they sense our closeness and are searching for us," noted Andreev.
By monitoring American radio broadcasts, Dubivko understood that the Soviet Union and the United States wer
e close to war. He was required to come to the surface at least once every twenty-four hours, at midnight Moscow time, for a prescheduled communications session. Nobody at navy headquarters paid attention to the fact that midnight in Moscow was midafternoon in the western Atlantic. The risk of detection rose sharply during the hours of daylight. Even so, Dubivko was terrified of missing a communication session. If war broke out while he was in the depths of the ocean, B-36 would automatically become a prime target for destruction by the American warships lurking overhead. His only chance of survival lay in firing his nuclear torpedo before he himself was destroyed.
Dubivko was expecting the coded signal from Moscow to start combat operations "from one hour to the next."
NOON FRIDAY, OCTOBER 26
Jack Kennedy was an avid consumer of intelligence. He enjoyed the voyeuristic sensation of peeking into other people's lives, and the power that came from the possession of secret information. He liked to see the raw data so that he could make his own judgments. When Andrei Gromyko visited the White House on October 18, four days after the discovery of Soviet missiles in Cuba, the U-2 photographs were sitting in the president's desk drawer just a few feet away. Kennedy had difficulty keeping his temper as the Soviet foreign minister continued to deny the existence of the missile bases. He told aides later that he could barely restrain himself from taking the incriminating photographs out of his desk and shoving them under the nose of the poker-faced Russian. He began referring to Gromyko as "that lying bastard."
Lundahl set up his easels in the Oval Office after the Friday morning ExComm meeting. He had brought along some of the latest low-level photography, and was eager to show the president the evidence of the rapid Soviet buildup. He reported that the ground was so drenched from recent rainstorms that the Soviets had erected catwalks around the missile sites, and were laying power cables on raised posts.
