Some time in 1968, somewhere in the northwest Pacific, the Soviet submarine surfaced to recharge its batteries. There was an explosion, perhaps caused by a spark that ignited trapped gases in the hull Before a single member of the crew could escape, the craft plummeted to the ocean floor about three miles below. But not to an unknown grave. U.S. Navy devices picked up the stricken submarine’s last throes and were able to place the wreckage within a ten-mile-square area. The Soviet navy was not so fortunate. A Soviet task force searched for traces of its missing vessel far from the actual site. When the Soviets finally gave up looking, U.S. authorities realized that only they knew the lost submarine’s resting place—and Project Jennifer was born. Part I: The Salvage Operation Project Jennifer, whose existence was disclosed last week, grew into an enterprise that eventually cost $350 million, employed more than 4,000 people, and brought into partnership America’s most secret institution, the CIA, and its most secret citizen, Howard Hughes. It also, in its way, pushed the limits of engineering and technology almost as far as Project Apollo, which took man to the moon, and may well have been the largest and most expensive espionage effort in the long history of man’s spying on man. The aim was simple: to raise the submarine from its grave without the Soviets’ knowledge, in order to learn some of the secrets of their nuclear weaponry, targeting and codes. The submarine was believed to be armed with three nuclear missiles and perhaps some nuclear-tipped torpedoes; like all Soviet warships, it had an array of sophisticated coding and decoding devices for secret communication. The first step was to locate the submarine precisely. The Navy dispatched to the waters north of Hawaii its ultrasecret research ship Mizar, a floating electronics laboratory. Like a fishing boat seeking to snare an exotic fish, Mizar put overboard an array of devices: sonar, electronic scanners, cameras equipped with powerful strobe lights, and a magnetic sensor that reacts to the presence of metal on the seabed. For two months Mizar patiently towed its paraphernalia across every inch of the ten-mile-square area until it had detected, scanned and thoroughly photographed the Soviet submarine. The next problem was to bring the sub to the surface. Since the operation would have to be paid for and carried out in deepest secrecy, the Navy turned to the CIA for help. One of the agency’s deputy directors presented the proposal to Richard Helms, then CIA director. “He damn near threw me out the window,” says the man, recalling Helms’ initial reaction. ” ‘You must be crazy,’ he told me.” Later, Helms began to see the beauty of the plan. Soon his other top aides, who knew nothing about the proposal, became curious about the brisk parade of Pentagon officials and high-ranking Navy officers that passed through Helms’ office. Once the green light was received from the White House, the CIA knew exactly whom they wanted to use as the cover for the submarine salvage: Howard Hughes, the eccentric billionaire who personally commands a business empire of airlines, hotels and electronics companies. Explains a CIA official: “The Hughes organization had the technical know-how for a project of that difficulty, and moreover Hughes has a passion for secrecy, which frankly was precisely what we had in mind.” There were other advantages. The new president of Hughes Aircraft, A.D. Wheelon, was an agency alumnus, and the upper ranks of the company were studded with former ranking military and CIA officers. Hughes was known to be intrigued by the possibility of mining the sea for mineral deposits. That interest would make an ideal cover under which to conceal the salvage operation. Hughes was also pleased—so pleased that he took the project on for very little fee profit. For the design of the entire recovery system, Hughes revived his old relationship with Lockheed Co. The firm, which has in recent years acquired expertise in deep-sea rescue vessels, developed an innovative design. The main ship—a hefty 36,000-tonner that would be 618 ft. in length and 115.5 ft. in beam—would serve as a floating, highly stable platform. Amidships would stand a high derrick that would pass piping directly through a well, or “moon pool,” in the ship’s hull, which could be opened or closed with a sliding panel. The ship’s companion was to be a huge submersible barge roughly the size of a football field, which would be covered by an oval roof. The barge’s purposes would be to carry the huge retrieval claws that would grapple for the submarine and later transport it to the U.S. The roof was meant to conceal its cargo from prying Soviet satellites. With those plans in hand, Hughes’ men sought out builders. They engaged the respected Los Angeles-based firm of Global Marine Inc. to supervise the construction of the ship and chose the Sun Shipbuilding & Dry Dock Co. to construct the ship, which was to be christened the Glomar Explorer. The barge, designated the HMB-1, was constructed by the National Steel & Shipbuilding Co. in San Diego. While the ships were abuilding, the Hughes people, who normally are noncommittal, delighted in spreading stories about Hughes’ deep-sea-mining plans. Everyone, including TIME (July 29), accepted Hughes’ account, and the press ran glowing stories about the ship’s capabilities. “If all sails smoothly,” went one typical newspaper account, “the mystery ship may be at work next year, scooping such metals as titanium, manganese, uranium, copper and nickel up out of the depths to add to the fortune of the world’s wealthiest recluse.” Shakedown Cruise. The Glomar Explorer’s 170-man crew was selected and put on contract by the CIA. The 40 men on the mining staff obviously knew the ship’s secret mission; the others probably did not. All refused to talk to outsiders about the ship, except to say that it had a gymnasium and the food was good. On Nov. 4, 1972, the Glomar Explorer was launched and left shortly thereafter on its shakedown cruise. According to one account, it tested its detection equipment and some of its recovery systems at the site of the 1968 accidental explosion of the U.S. nuclear-powered submarine Scorpion, which went down near the Azores in about 10,000 ft. of water. Then Glomar Explorer, her beam too wide for the Panama Canal, sailed round the Horn and made for Los Angeles, where she rendezvoused with her companion, HMB-1\. Fittingly, Glomar Explorer docked at Long Beach’s Pier E, which is located only about 50 yds. from the hangar that for years has housed Hughes’ gigantic plywood flying boat, known irreverently as “the Spruce Goose.” Though Howard Hughes last month finally agreed to dispose of the Goose, giving parts of it to the Smithsonian, it remains at present in the hangar, a monument to his single-minded determination. Delicate Operation. Sightseers were barred from approaching either the ship or the barge. When local fire officials insisted upon inspecting HMB-1, they found its interior completely shrouded by tarpaulins. “Surveillance TV cameras follow anyone who approaches the barge, and guards with big pistols walk beside you on board,” reported a tug pilot who once towed the barge. Towing the ungainly barge in her wake, the Glomar Explorer headed for the open sea on June 20, 1974, ready at last to attempt the culmination of Project Jennifer. By about mid-July the odd convoy reached the site of the sunken Soviet sub. The delicate salvage operation got under way. Despite the chop of waves and force of the current, it was necessary for the Glomar Explorer to maintain an almost impossible stationary position, straying no more than 50 ft. in any direction. To do that, the ship dropped a series of bottom-placed transducers, which detected the force and direction of the water’s flow and transmitted that information to a shipboard computer. The computer, in turn, kept the ship in one place by activating a series of water jets and small propellers placed at intervals along the ship’s hull. Next the barge opened its sea cocks until it had taken on enough water to sink to a depth of 150 ft. It was maneuvered directly beneath the Glomar Explorer’s moon pool and held in place by stanchions from the mother ship. Pipe from the ship reached down to the barge and attached itself to the giant grappling claws, which resembled a series of four or six interconnected ice tongs hanging from a long platform. Then the ship’s crew began to feed length after length of pipe through the hole. By the time the claw reached the Soviet submarine 16,000 ft. below, the pipe alone weighed more than 400,000 Ibs. Television cameras equipped with strobe lights enabled the claw operators to see what they were doing (see diagram page 25). One by one, the giant grapnels, which were attached by cables to the Glomar Explorer, seized sections of the stricken submarine in their steel jaws. Slowly the winches aboard the Glomar Explorer began to lift the submarine from its grave, tugging hard to unstick the hull from the seabed. It was a nerve-racking process. The submarine’s dead weight of at least 4,000 tons taxed even Glomar Explorer’s powerful winches. The ship shuddered and reverberated with the protesting scream of straining electric engines and the scrape of taut steel cables. At some point in the lift—one estimate places it at about halfway up the 16,000 ft.—the cables rattled. Though the cause remains a secret, the consequence was soon evident. The sub’s hull, already weakened and damaged by the explosion and severe water pressures, cracked into two pieces. According to the CIA’s account, the aft two-thirds, including the conning tower and the coveted missiles and code room, slipped back to the seabed. The forward third, which remained gripped firmly in the grapnels, was deposited in the still submerged barge. Blowing its water ballast, HMB-1 rose to the surface. Even if only partially successful, as the CIA claims, the mission was a major technological achievement. Nothing so large had ever before been raised from so great a depth. Aware that the salvage operation would also raise the bodies of the dead Russian officers and men, the CIA had made what it felt was the proper arrangements. The Glomar Explorer was equipped with special cooling facilities that could accommodate up to 100 corpses. In the forward section of the submarine were a number of bodies. While a loudspeaker played a recording of the Soviet national anthem, a funeral service was read in Russian and English. As a CIA cameraman filmed the proceedings in color and sound, the bodies were buried at sea from the Glomar Explorer, each neatly shrouded in canvas. Part II: Aims of the Mission Was the Project Jennifer trip necessary? Would it have been worth its high price tag if the entire submarine had been recovered? Some congressional critics of the CIA last week said no; Senator Frank Church suggested that the agency had wasted money on the project, saying, “No wonder we are broke.” By contrast, a top CIA official insists that had the project succeeded, it would have been “the biggest single intelligence coup in history.” Such a claim rests on the incredibly complex and ever-changing nature of military technology. To U.S. analysts, the sunken submarine contained a potential treasure-trove of invaluable and hitherto unattainable information. No outsider can imagine the degree to which the U.S. and the Soviet Union are locked in intense competition to gain an edge, no matter how slight, over each other in a whole array of weapons systems and intelligence-gathering devices. Hence each side seeks to find out all it can about the other’s weaponry, countermeasures, and research. U.S. experts study Soviet equipment captured from Arab armies by the Israelis, but that is only conventional weaponry. For knowledge about Soviet nuclear missiles, the U.S. relies mainly on the pictures of Soviet missiles taken by intelligence satellites that course across Soviet skies and aerial reconnaissance shots of Soviet test firings that record the re-entry of Soviet warheads in the Pacific. But so far as is known, U.S. experts have never had the opportunity to run their hands over a Soviet nuclear warhead, or look inside. Nor, presumably, have U.S. cryptographers ever had the chance to examine the construction of a Soviet cipher machine or to read Soviet code books. The sunken submarine offered those opportunities. The diesel-driven ship of the G or Golf class (vintage 1958-62) had long since been made obsolescent by the Soviet nuclear-powered submarines of the Yankee and Delta classes. Nonetheless, in the superstructure behind its tall conning tower, the submarine typically carried three nuclear-tipped missiles of the Serb class, which has a 650-mile range and a 500 kiloton warhead. At the time the SALT I negotiations were about to start, and an examination of the Serb warheads would have given U.S. experts an invaluable insight into the state of Soviet nuclear technology. They could have learned about the reliability, accuracy and method of triggering the nuclear matter of Soviet missiles. They could have compared their earlier evaluations based on satellite data against the real thing. Hence U.S. negotiators could have entered the SALT talks with the advantage of having a clearer understanding of Soviet nuclear strength. Defense System. In 1968 the U.S. was building a widespread anti-missile defense system intended to intercept and destroy Soviet ICBMS before they struck American cities. A study of the guidance system and flight characteristics of the Soviet warhead would have enabled U.S. scientists to program more effectively the computers directing the U.S.’s targeting radar. There were other incentives. The Navy had never examined a Soviet torpedo; the G-class subs carried at least ten in bow and aft tubes. U.S. naval experts also had never subjected the steel used in Soviet sub hulls to metallurgical analysis. Test results could tell them how deep Soviet subs can dive, a vital bit of information in undersea warfare. The U.S. intelligence community has its own special enthusiasms. Aboard the sub were cipher machines and Soviet code manuals; provided they were stored in watertight safes, those manuals might still be legible. “It would be an absolutely unique, unprecedented opportunity to capture an entire Soviet code room,” said a ranking U.S. intelligence expert. “We have never before had access to the Soviets’ top-secret cryptographic equipment or to any individual who had worked inside one of their code rooms.” In retrospect, many intelligence experts now play down the potential value of obtaining a code machine and possibly a legible code book. They point out that code machines, Western and Russian models alike, are constructed in a manner that enables the operator to reset circuits and insert new encoding or decoding disks at random so that yesterday’s code may give scant clue to today’s. Even so, influential U.S. cryptologists at the time believed that an examination of the Russian equipment would increase the possibility that the U.S. might finally succeed in breaking Soviet codes, a feat that in 1968 had still defied the best efforts of the American intelligence community. Part III: The Story Gets Out Although so many thousands of people worked on Jennifer in a dozen Government departments and private companies, the project was a remarkably well-kept secret for more than six years. There were occasional suspicions. Famed Oceanologist Jacques Yves Cousteau, for example, said last week that he had always thought Hughes’ mining scheme implausible but that “we had to treat it seriously because we all knew that Howard Hughes does not involve himself in uneconomic undertakings.” Some knowledgeable defense contractors and electronics makers doubted the Glomar Explorer’s stated purpose because of the extraordinary specifications of contracts, such as those for the giant grappling hooks and the cryptographic equipment. The fact that the seamen of the Glomar Explorer were not permitted to frequent the usual Long Beach bars aroused local curiosity. But the CIA had only two real security scares before the story finally broke. The first came in 1973, when a labor dispute erupted between engineers and the mining complement on board the Glomar Explorer. The engineers resented the fact that the mining technicians, rather than the captain, really ran the ship. That dispute moved quietly into the courts. The second scare came shortly before the Glomar Explorer put to sea to salvage the submarine. A rash of burglaries of Hughes’ company offices scattered across the West culminated in the early morning of June 5, 1974, in a break-in of Hughes’ two-story communications and storage center at 7000 Romaine Street in Los Angeles. A group of four or five armed men slipped past a formidable electronic alarm system and heavy locks and overwhelmed the guard. Using acetylene torches, the men burned their way into the safes and filing cabinets that contained some of Hughes’ most sensitive documents, including one memo outlining his participation in Jennifer. Since the robbery was executed with such un erring accuracy, some people speculated that either it was an inside job in which Hughes had in effect robbed himself to get rid of incriminating documents, or the CIA did the favor for him. Then a man claiming to represent the burglars offered to return the documents in exchange for $500,000\. Alerted that the stolen papers could endanger national security, the FBI tried to buy them back, but the deal fell through. Last week a grand jury in California returned a secret indictment in the theft. It reportedly cited only one defendant, Donald Woolbright, who is still at large. But in the process of investigating the theft, local police got into the act, and eventually the Los Angeles Times got a garbled version of Jennifer from a tipster. On Feb. 8 of this year the newspaper ran a story about a CIA-Hughes contract to raise a Soviet submarine supposedly sunk in the Atlantic. The CIA waited with bated breath to see if the rest of the press would pick it up or, worse, if the Soviets would. Astonishingly, insists the CIA, the Soviets did not, which presumably means that there are some very nervous KGB agents somewhere in the Western Hemisphere this week. But the press kept asking the CIA questions about Howard Hughes and submarines. Eventually, Director Colby moved to suppress the story, pleading national security. His rationale: since Moscow still had not got wind of Jennifer, Glomar Explorer this summer would return in good weather to attempt to raise the rest of the submarine, and secrecy was needed to protect the operation. All this posed a sharp dilemma for editors (see THE PRESS). Quick Switch. What Colby offered was unusual: briefings on Jennifer in exchange for silence. He seemed to feel that only by being briefed on the stakes involved could the press be expected to join the conspiracy of silence. A curious turnabout took place once the story did become public: the CIA had nothing more to say about Jennifer. The formula seemed simple if slightly surreal: “We’ll tell you something if you won’t tell anybody; now that you’ve told everybody, we won’t tell you anything.” Reason for that wall of silence: by not publicly admitting the existence of Jennifer, the U.S. hopes to permit the Soviets to avoid any official response that could damage relations between the two nations. Soviet Party Leader Leonid Brezhnev is due to visit the U.S. this summer, and CIA officials remember all too well that Moscow used the U-2 spy-plane incident to ruin a summit in 1960\. Last week, when the Jennifer saga broke, the acting Soviet ambassador in Washington sent a strong cable to Moscow advising the Kremlin to make a firm protest to Washington. But Moscow has remained silent, and the Soviet press has not mentioned the matter at all. Part IV: Puzzling Aftermath A host of puzzles large and small clings to the Jennifer story. Example: Why was Hughes so anxious to make the CIA connection that the Jennifer partnership represented? According to Robert Maheu, an ex-FBI agent and former manager of Hughes’ operations in Nevada, the billionaire had tried for years to arrange a connection with the CIA. Explained Maheu: “He wanted it so that Uncle Sam could never take after him. If he got in a jam with the Internal Revenue Service or the Securities and Exchange Commission, they couldn’t afford to touch him because of what he was doing with the CIA.” But it was the agency, in fact, that made the initial approach to Hughes about Project Jennifer. It was followed, however, by several other arrangements, TIME has learned. For example, the agency supplied information about Maheu in connection with his successful defamation suit against Hughes for calling him a thief. For their part, Hughes’ employees kept the CIA informed about the activities of White House Plumber E. Howard Hunt. Among other things, they reported that he had interviewed ITT Lobbyist Dita Beard and planned to rifle the files of Las Vegas Publisher Hank Greenspun in search of information that might embarrass Democratic Presidential Candidate Edmund Muskie. At the time, ex-CIA Agent Hunt was also working for Robert R. Mullen & Co., a now defunct public relations firm in Washington that provided cover for CIA agents in Europe and the Far East. The firm was headed by Robert Bennett, who also worked for Hughes. Then there is the puzzle of why so many reporters for major newspapers, magazines and TV networks simultaneously stumbled upon the Jennifer trail. On the morning after, some journalists got the feeling that the CIA had actually been helpful all along in getting the story out, while at the same time it apparently tried to suppress the story. There are several theories, including the reasonable possibility that the agency effort was just what it seemed to be. Another is that, battered by a lot of bad publicity of late, the agency felt that it was time for some good news. Jennifer was a clean, highly creative enterprise that had served its purpose. A third and by no means improbable theory has it that in fact Jennifer wholly succeeded: the entire submarine, missiles, codes and all, was raised intact and gleaned. But with the story beginning to leak out, it was decided to make one final effort to deceive the Soviets on the extent of the coup by floating a version of only partial success. The last theory goes off into the wild blue yonder, suggesting that raising a Soviet submarine was not Jennifer’s mission at all, but the supreme cover for a secret mission as yet safely secure. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6817157/espionage-the-great-submarine-snatch/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6817157/espionage-the-great-submarine-snatch/"},"headline":"ESPIONAGE: The Great Submarine Snatch","datePublished":"1975-03-31T04:00:00.000Z","dateModified":"2026-03-04T02:57:21.149Z","description":"It all began with an accident.
