Aluminaut had battery trouble, Alvin had sonar problems, and neither could navigate easily. Cubmarine was great, but only down to 600 feet. All in all, summarized Guest, “We enter this phase with equipment largely R&D and of marginal reliability and ruggedness.”
Then Guest laid out his four search areas. Two were top priority: Alfa 1 and Alfa 2. One, a semicircle adjacent to the beach, extended the aircraft debris pattern into the ocean. For the other, Guest located the point where Simo had seen the “dead man” and his parachute hit the ocean, then noted eleven sonar contacts nearby. He averaged those sonar hits, noted that point on the chart, and drew a one-mile-radius circle around it. Guest also identified two other areas based on Sandia calculations. These, large rectangles stretching into the sea, were named Bravo and Charlie.
Altogether, the four search areas encompassed about twenty-seven square miles of ocean. Guest had narrowed down the search area from two Manhattans to just over one. His task force would now have to sweep every inch of it for the missing bomb.
To divide these four large areas into searchable zones, Guest's team created a 132-square-mile grid system that they could lay over his charts. They first divided the area into lettered two-by-four-mile rectangles, then divided each of those into thirty-two numbered squares, each measuring 1,000 by 1,000 yards.
Guest depended on divers, sonar, and Cubmarine to handle the areas close to shore. Then, with Brad Mooney's advice, he made a plan for the submersibles. The more maneuverable Alvin got the deeper areas near Simo's sighting, where the underwater terrain rose and fell with rugged ridges and trenches. Aluminaut was sent to cover shallower, smoother areas, a plan that irritated her crew. Like almost everyone else, they thought that Simo Orts had seen the bomb fall and wanted to search there.
Mooney understood the crew's feelings, but he had reservations about Aluminaut. Aluminum, if exposed to salt water, can suffer catastrophic failures. So, for protection, builders coated Aluminaut with several layers of colored paint. After almost every dive, the submersible's support crew checked the hull for scratches or scars that might expose the aluminum to salt water. This vulnerability
“probably scared a lot of people from using her very much,” said Mooney. “Did me.” Such concerns annoyed the Aluminaut crew to no end. Art Markel, the manager of the Aluminaut team, thought his ship was far more capable than the Navy gave it credit for, and certainly more adept at deepwater searching than Alvin. Aluminaut was outfitted with search sonars that could read out to 800 feet, as well as a sweeping sonar that could see 2,000 feet. Alvin had nothing so elaborate.
“They were using eyeballs,” said Markel. “When you used an eyeball, you could see about fifty feet at the most. Fifty feet, that's all. The rest of it's black.” On one of their first dives, the Aluminaut sonars picked up a sunken Spanish ship, which appeared to be quite old. Markel suggested that his bosses at Reynolds contact the Spanish government regarding salvage rights. Perhaps Aluminaut could retrieve a cannon from the “ship of antiquity,” as he called it, or even a treasure chest full of gold. He also suggested to Guest that they go back into the area and use the sunken ship as a target for calibrating Aluminaut's sonar. Markel's request irked the admiral. Stop fooling around with Spanish galleons, he told Markel. We're looking for a hydrogen bomb.
Guest had little time to worry about the Aluminaut crew's bruised feelings. The Soviets had just cranked the international tension up a notch, putting the lost bomb into the middle of the fray. On February 16, the Soviet foreign minister handed a memorandum to the American ambassador to Moscow, charging the United States with violating the 1963 Limited Test Ban Treaty by dropping bombs on Palomares and contaminating the atmosphere. The following day, the same day that Guest laid out his search plans for the chief of naval operations, the Soviets upped the ante. At a disarmament conference in Geneva, the Soviet delegate, Semyon Tsarapkin, took the floor and read the accusatory memo to the entire assembly. Washington, said Tsarapkin, was endangering foreign lands and people with its B-52 missions. Only “a fortunate stroke of luck” had prevented an atomic catastrophe in Spain; America must end the nuclear flights without delay.
U.S. diplomats dismissed these charges as ridiculous, but they made international news and refocused attention on the missing bomb. And the Soviets weren't the United States' only diplomatic headache. A week later, President Charles de Gaulle of France announced that, by 1969, all military bases on French soil would be taken under French control. The United States, at the time, had several large Air Force bases in France, as well as a Navy headquarters and a number of Army supply and communication centers. If de Gaulle kicked the Americans out of France, it would likely heighten the importance of the U.S. bases in Spain. Ambassador Duke received assurances that the Spanish government would not take “Machiavellian advantage” of the situation, but every day the bomb stayed lost, the Spanish government gained more diplomatic clout.
Though not directly involved in any of these incidents, Admiral Guest surely felt pressure from all of them. His daily situation reports were often read by the chief of naval operations and sometimes by the secretary of defense and the president of the United States. Having to report no progress, day after day, was tremendously demoralizing. Red Moody said that he had never — even in combat — seen a flag officer under such pressure as Guest.
The admiral soon faced a problem closer to home: a Soviet spy ship, the Lotsman, cruising near the search areas. Guest, with permission from the Spanish, had established a large restricted zone in the Mediterranean encompassing the Alfa and Bravo search areas. He had then sent a Navy destroyer to patrol the boundaries. On February 17, the destroyer reported the arrival of the Lotsman. The Soviet ship was well known to the Americans — she usually cruised near Rota Naval Air Station — and she didn't try to hide. For about two weeks Guest sent the Navy destroyer USS Wallace L. Lind to shadow the Soviets, just in case they tried any funny business.
The Lotsman sat low in the water, covered with rust. If anything happened, she was no match for the Lind. The Navy destroyer, about twice the size of the Lotsman, was built for antisubmarine warfare and armed with torpedoes, bombs, and guns. But occasionally the Soviets pushed their luck. On at least one night, the Lotsman steamed toward the Lind, trying to intimidate the American ship and force it to give way. The Lind held its ground. Anthony Colucci, the twenty-five-year-old lieutenant deck officer, recalled the Lotsman coming within twenty-five yards of the Lind. Colucci, who had served on an amphibious ship during the Cuban Missile Crisis, knew a few things about Cold War tension. But this was personal. “There were certainly more important strategic concerns,” he said.
But “when the captain is asleep and the Lotsman is coming in closer and closer to me, what was I thinking? I was thinking ‘Oh crap, there's gonna be a collision.’” News of the Lotsman's snooping rippled through the task force, inviting speculation on what the Russians might try next. At the time, the Soviets had two advanced submersibles that could dive to 6,500 feet. Supposed they pulled a Thunderball, dove down, and picked up the bomb themselves?
Or, even worse, suppose a Soviet submarine slipped into the search area and released a timed nuclear device? The bomb would explode, and everyone would point fingers at the Americans.
The Lotsman stayed on scene until early March, usually cruising between five and eleven miles away from Alfa 1. Then she vanished. Nobody knew what she had learned during her stay.
From Washington, Guest's Technical Advisory Group kept a close eye on the developments in Spain.
Even if the bomb had fallen into the sea, Guest might never find it. If the admiral came up empty-handed, the Navy would have to stand before Congress — and the secretary of defense — and explain why it had spent so much money on an unsuccessful search. Heads would roll.
The TAG understood this clearly. The advisers were not only sending gear to Spain, they were also thinking about the endgame. If the search failed and the Navy brass were hauled before Congress, they would need proof that Guest had done everything possible to find the bomb. Or at least they would need something that seemed like proof-some fancy numbers to wave in front of the politicians. What they needed, they decided, was math.
