In addition, the Air Force was sending planes armed with filters designed to capture radioactive particles near Soviet territory to gauge whether the Soviets were testing atomic weapons. That was the ultimate fear, that the buzz bombs would be given nuclear warheads, that they would lead to atomic missiles.

Much of this was still conjecture. What little information the intelligence agencies had about the Soviet Navy was coming from Britain's Royal Navy, which had worked closely with the Soviets during World War II. Communications between Soviet ships and their bases were also being intercepted by U.S.-operated eavesdropping stations in Europe and Alaska. All of this spying on a former ally was so sensitive that messengers carried reports on the intercepted Soviet communications to top admirals in locked briefcases. Any efforts to get closer, to learn more, needed to be kept a deep secret.

It was that need for stealth that, more than anything, convinced intelligence officials that submarines could be the next logical step in the creation of an eavesdropping network that would circle the Soviet Union. The effort was already under way. In 1948 the Navy had sent two fleet boats, the USS Sea Dog (SS-401) and the USS Blackfin (SS-322), into the Bering Sea to see whether they could intercept Soviet radio communications and count how quickly propeller blades turned on Soviet destroyers and merchant ships--a first step toward learning to identify them through passive sonar. But intelligence officials suspected that the new snorkel subs, like Cochino, could do even more. They could stay hidden off the Soviet coast and watch and monitor. Perhaps they could even find out firsthand how far along the Soviets were in developing the dangerous missile technology. With her snorkel, Cochino could sneak in as close as she dared. Only her periscope, antennas, and snorkel would ever have to broach into the open air. She was, in short, the perfect spy vehicle.

In fact, Cochino had been destined from the start for a different fight. She had been the last submarine commissioned during the war, sent to sea two weeks after the Enola Gay dropped the first atomic bomb. Now she and the USS Tusk (SS-426) had been remade with those snorkels and other advances, and turned into what the Navy called "GUPPYs," an acronym that stood for Greater Underwater Propulsion Power. The acronym fit far better than anyone would have liked--as hunter-killers, these subs were rank beginners, learning to swim all over again. In fact, when scientists checked the boats a few months before this trip, they had discovered that their crews and construction personnel knew so little about the passive sonar systems that crucial hydrophones had not even been hooked up. So the boats had been sent to Londonderry to practice with the British, who had gotten much further in mastering the new sonar.

It was in Londonderry that Austin caught up with Cochino. Also on board was a civilian sonar expert, Robert W. Philo, who was working as a consultant. The hunter-killer exercises were considered so important that the leader of Operation Kayo, Commodore Roy S. Benson, had come along and would end up on Tusk, commanded by Robert K. Worthington.

Like Benitez, Worthington had taken command just days before they were all to leave for this trip, and like Benitez, Worthington and Benson were skeptical of their new trek into espionage. Benson believed that, at best, it was a side mission, one that wasn't nearly as important as training in the art of true underwater warfare. Red Austin thought he knew better. But then again, this spy stuff seemed to be his calling.

"I got to have something spooky to do," Austin liked to say. "It's just the way I am."

But if all of this was second nature to Austin, it wasn't to others. His special equipment was to be installed in a shipyard in Portsmouth, England, where even the yard workers were somewhat befuddled by the new gear.
