John Anthony Walker

Walker cooperated somewhat with authorities, enough to form a plea bargain that reduced the sentence for his son. He agreed to submit to an unchallenged conviction and life sentence, to provide a full disclosure of the details of his spying and to testify against Whitworth in exchange for a pledge from the prosecutors that the maximum sentence requested for Michael was 25 years imprisonment, which was later Michael's sentence. All the members of the spy ring besides Michael Walker received life sentences for their role in the espionage. Whitworth was sentenced to 365 years in prison and fined $410,000 for his involvement. Whitworth was incarcerated at the United States Penitentiary, Atwater, a high-security federal prison in California. Walker's older brother Arthur received three life sentences plus 40 years and died in the Butner Federal Correctional Complex in Butner, North Carolina on July 5, 2014, six weeks before the death of his younger brother.

Walker died while he was suffering from cancer and diabetes on August 28, 2014, while still in prison. He would have become eligible for parole in 2015.

When Walker began spying, he worked as a key supervisor in the communications center for the U.S. Atlantic Fleet's submarine force, and he would have had knowledge of top-secret technologies, such as the SOSUS underwater surveillance system, which tracks underwater acoustics via a network of submerged hydrophones. It was through Walker that the Soviets became aware that the U.S. Navy was able to track the location of Soviet submarines by the cavitation produced by their propellers. After this, the propellers on the Soviet submarines were improved to reduce cavitation. The Toshiba-Kongsberg scandal was disclosed in this activity in 1987. It is also alleged that Walker's actions precipitated the seizure of USS Pueblo. CIA historian H. Keith Melton states on the show Top Secrets of the CIA, which aired on the Military Channel, among other occasions, at 0400CST, February 5, 2013:

In the June 2010 issue of Naval History Magazine, John Prados, a senior fellow with the National Security Archive in Washington, D.C., pointed out that after Walker introduced himself to Soviet officials, North Korean forces seized USS Pueblo in order to make better use of Walker's spying. Prados added that North Korea subsequently shared information gleaned from the spy ship with the Soviets, enabling them to build replicas and gain access to the U.S. naval communications system, which continued until the system was completely revamped in the late 1980s. It has emerged in recent years that North Korea acted alone and the incident actually harmed North Korea's relations with most of the Eastern Bloc.

Walker's son, Michael, who had a relatively minor role in the ring and agreed to testify in exchange for a reduced sentence, was released from prison on parole in February 2000. Walker was incarcerated at FCC Butner, in the low security portion. He was said to suffer from diabetes mellitus and stage 4 throat cancer.

In 1990, The New York Times journalist John J. O'Connor reported, "It's been estimated by some intelligence experts that Mr. Walker provided enough code-data information to alter significantly the balance of power between Russia and the United States". Asked later how he had managed to access so much classified information, Walker said, "KMart has better security than the Navy". According to a report presented to the Office of the National Counterintelligence Executive in 2002, Walker is one of a handful of spies believed to have earned more than a million dollars in espionage compensation, although The New York Times estimated his income at only $350,000.

In late 1985, Walker made a plea bargain with federal prosecutors, which required him to provide full details of his espionage activities and testify against his co-conspirator, former senior chief petty officer Jerry Whitworth. In exchange, prosecutors agreed to a lesser sentence for Walker's son, former Seaman Michael Walker, who was also involved in the spy ring. During his time as a Soviet spy, Walker helped the Soviets decipher more than one million encrypted naval messages, organizing a spy operation that The New York Times reported in 1987 "is sometimes described as the most damaging Soviet spy ring in history."

When both Barbara Walker and Laura Walker passed polygraph examinations, electronic surveillance was authorized by the Foreign Intelligence Surveillance Court against John Walker. In May 1985 the FBI learned through the electronic surveillance that it was likely that John Walker would travel out of town on the weekend of May 18 and 19, 1985. On May 19 Walker left his house in Norfolk and was followed covertly by the FBI to the Washington, D.C., area, where the surveillance was joined by personnel from the FBI's Washington field office. Later that evening about 8:30 p.m. he drove to a rural area in Montgomery County, Maryland, where he was seen placing a package in a wooded area near a "No Hunting" sign. The FBI retrieved the package that was found to have 124 pages of classified information stolen from the aircraft carrier USS Nimitz, where Walker's son, Michael, was assigned. John Walker was arrested during the early morning hours of May 20, 1985, by a team of agents from the Norfolk and Washington FBI field offices. The FBI apprehended Walker himself at a motel in Montgomery County by telephoning his hotel room and telling him that his car had been hit in an accident. Barbara Walker was not prosecuted because of her role in disclosing the ring. Former KGB agent Victor Cherkashin, however, describes in his book Spy Handler that Walker was compromised by FBI spy Valery Martynov, who overheard officials in Moscow speaking about Walker.

John and Barbara Walker divorced in 1976. Their marriage was marked by physical abuse and alcohol. By 1980 Barbara had begun regularly abusing alcohol and was very fearful for her children. She wanted the children not to become involved in the spy ring; that led to constant disagreement with John. Barbara tried several times to contact the Boston office of the FBI, but she either hung up or was too drunk to speak. In November 1984 she again contacted the Boston office and in a drunken confession reported that her ex-husband spied for the Soviet Union. She did not then know that Michael had become an active participant; she later admitted she would not have reported the spy ring had she known her son was involved.

Walker was transferred from San Diego in December 1971 to become the communications officer aboard the supply ship USS Niagara Falls. Whitworth, who would become a Navy senior chief petty officer/senior chief radioman, agreed to help Walker gain access to highly classified communications data in 1973; and served aboard Niagara Falls after Walker retired from the Navy. Transfer to the staff of commander of the Amphibious Force, Atlantic Fleet had stopped Walker's access to the data the Soviets wanted; but he recruited Whitworth to keep the data flowing – softening the idea of espionage by telling him the data would go to Israel, an ally of the United States. Later, when Whitworth realized the data was going to the Soviets instead of Israel, he nonetheless continued supplying Walker with information, until Whitworth's retirement from the Navy in 1983.

In the spring of 1968 John Walker's wife discovered items in his desk at home causing her to suspect he was acting as a spy. Walker continued spying, receiving an income of several thousand dollars per month for supplying classified information. Walker used most of the money to pay off his delinquent debts and to move his family into better neighborhoods, but he also set aside some for future investment, such as turning around the fortunes of his money-losing bar by hiring a skilled bartender. While Walker occasionally used the services of his wife, Barbara Walker, he anticipated the possibility of losing access due to reassignment. Walker's chance to seek further assistance came in September 1969 when he became the deputy director of the radioman A and B schools at the Naval Training Center San Diego. There, Walker befriended student Jerry Whitworth.

John Walker was promoted to warrant officer in March 1967 and in April was assigned as a communications watch officer at the headquarters of COMSUBLANT in Norfolk, Virginia, where his responsibilities included "running the entire communications center for the submarine force...." Walker began spying for the Soviets in late 1967, when, distraught over his financial difficulties, he walked into the old Soviet embassy in Washington, D.C., sold a top-secret document (a radio cipher card) for several thousand dollars, and negotiated an ongoing salary of US$500 (equivalent to $4,063 in 2021) to US$1,000 (equivalent to $8,127 in 2021) a week. Soviet KGB general Boris Aleksandrovich Solomatin "played a key role in the handling of John Walker". Walker justified his treachery by claiming that the first classified Navy communications data he sold to the Soviets had already been completely compromised when the North Koreans had captured the U.S. Navy communications surveillance ship, USS Pueblo. Yet the Koreans captured Pueblo in late January 1968 – many weeks after Walker had betrayed the information. Furthermore, a 2001 thesis presented at the U.S. Army Command and General Staff College using information obtained from Soviet archives and from Oleg Kalugin, indicated that the Pueblo incident may have taken place because the Soviets wanted to study equipment described in documents supplied to them by Walker. It has emerged in recent years that North Korea acted alone and the incident actually harmed North Korea's relations with most of the Eastern Bloc.

John Anthony Walker Jr. (July 28, 1937 – August 28, 2014) was a United States Navy chief warrant officer and communications specialist convicted of spying for the Soviet Union from 1967 to 1985 and sentenced to life in prison.

Walker was born in Washington, D.C., on July 28, 1937, and attended high school in Scranton, Pennsylvania. After dropping out of high school, Walker and a friend staged a series of burglaries on May 27, 1955. Their loot included two tires, four quarts of oil, six cans of cleaner, and $3 in cash. The pair evaded police during a high-speed chase, but were arrested two days later. He was offered the option of jail or the military. He enlisted in the Navy in 1955, and successfully advanced as a radioman to chief petty officer in eight years. While stationed in Boston, Walker met and married Barbara Crowley, and they had four children together, three daughters and a son. While stationed on the nuclear-powered Fleet Ballistic Missile (FBM) submarine USS Andrew Jackson in Charleston, South Carolina, Walker opened a bar, which failed to turn a profit and immediately plunged him into debt. In 1965 Walker transferred to the newly built FBM, USS Simon Bolivar, where he received a top secret crypto clearance to work in the submarine's communications spaces. He and other members of the submarine's communications team were members of the John Birch Society, distributing literature about the organization to crew members and to friends ashore, where Walker attempted the playboy lifestyle.

In 1976, Walker retired from the Navy in order to give up his security clearance, as he believed certain superior officers of his were too keen on investigating lapses in his records. Walker and Barbara had also divorced. However, Walker did not end his espionage, and began looking more aggressively among his children and family members for assistance (Walker was a private investigator during this time). By 1984, he had recruited his older brother Arthur James Walker (August 5, 1934 – July 5, 2014), a retired lieutenant commander who served from 1953 until 1973 and then went to work at a military contractor, and his son Michael Lance Walker (born November 2, 1962), an active duty seaman since 1982. Walker had also attempted to recruit his youngest daughter, who had enlisted in the United States Army, but she cut her military career short when she became pregnant and refused her father's offer to pay for an abortion, instead deciding to devote herself to full-time motherhood. Walker then turned his attention to his son, who had drifted during much of his teenage years and dropped out of high school. Walker gained custody of his son, put him to work as an apprentice at his detective agency in order to prepare him for espionage and encouraged him to re-enroll in high school to earn a diploma, then to enlist in the Navy.
