USS Jack (SSN-605)

Upon commissioning, JACK was assigned to Commander Submarine Squadron 10 in New London, Connecticut. Jack spent her entire career assigned to Squadron 10. After a shakedown cruise in the Caribbean, Jack took her place in the operational fleet.

On 22 June 1968, Commander David G. Smith relieved Commander Urbanczyk of command of Jack at State Pier in New London, Connecticut.

In September and October 1968, the North Atlantic Treaty Organization (NATO) held Exercise Silver Tower, its largest combined naval exercise since 1964. The exercise – one of a series of major maritime exercises designed to test NATO plans and defenses under simulated battle conditions – brought together aircraft and about 200 ships from Belgium, Canada, Denmark, the Netherlands, Norway, Portugal, the United Kingdom, the United States, and West Germany, including destroyers and frigates from NATO's new multinational Standing Naval Force Atlantic. Soviet Navy ships shadowed the exercise, which depicted an imaginary threat to Norway posed by political and military pressure from an adversary nation called "Orange." During Silver Tower, Jack very successfully demonstrated the capabilities of a modern nuclear submarine, playing the role of an "Orange" submarine opposing both underway replenishment groups and a large aircraft carrier task force, and she claimed a simulated sinking tonnage of 319,000 displacement tons; during all of World War II, the three top-scoring United States Navy submarines – USS Flasher (SS-249), USS Rasher (SS-269), and USS Tang (SS-306) – had sunk a combined total of just over 293,956 gross register tons of enemy merchant shipping and displacement tons of enemy warships. After the exercise, when key representatives from each participating ship assembled in the United Kingdom at Rosyth Dockyard in Rosyth, Scotland, for a presentation of the results of the exercise, Jack received special mention as a result of her outstanding performance during the exercise.

After the conclusion of Silver Tower, Jack returned to Portsmouth Naval Shipyard late in 1968 for a four-month post-shakedown shipyard availability.

Completing the availability in March 1969, Jack participated in a Caribbean training exercise, Exercise Springboard. As a result of Jack's performance during the exercise, her weapons department was awarded the Battle Efficiency "E" for fire control excellence.

Later in 1969, Jack was assigned a secret special operation. The performance of the crew during that operation resulted in the following letter from the Chief of Naval Operations:

"The Secretary of the Navy takes pleasure in presenting the Meritorious Unit Commendation to USS JACK (SSN-605) for service as set forth in the following CITATION:

"For meritorious service during a period in 1969 in conducting an important and arduous independent submarine operation. In successfully completing the operation, USS JACK achieved significant results of great importance to the national defense of the United States. These results were attained primarily through the professional skills, resoursefulness, and teamwork of USS JACK's officers and men. Their dedication to the fulfillment of a vital and difficult assignment reflects credit upon themselves and the United States Naval Service. All personnel attached to and servind on board USS JACK (SSN-605) during the period of this citation are hereby authorized to wear the Meritorious Unit Commendation Ribbon.

"For the Secretary, /s/ T. H. Moorer, Admiral, United States Navy, Chief of Naval Operations."

Jack later received a second Meritorious Unit Commendation. On 26 June 1969 Jack tested the performance of an armed Mark 16 torpedo by sinking a target ship, the decommissioned destroyer escort USS Snowden (DE-246).

During the summer of 1970, while Jack was engaged in midshipmen training at the United States Naval Academy in Annapolis, Maryland, she was awarded the Battle Efficiency "E" by Commander, Submarine Force, Atlantic.

On 11 February 1971, Jack arrived at the Portsmouth Naval Shipyard to begin an extensive, 12-month overhaul.

In early 1972, toward the end of her overhaul, the United States Atlantic Fleet's Operational Reactor Safeguards Examining Board inspected Jack. The board conducted interviews of crew members, observed operational drills, examined records, and tested the knowledge of crew members. Upon completion of the inspection, Jack received the highest grade awarded by the fleet commander's examining board.

On 22 July 1972, Commander Thomas F. Wiener relieved Commander David G. Smith as commanding officer of Jack. Shortly thereafter, on 31 July 1972 Jack deployed to the Mediterranean as part of a build-up of the US navy in that operational area. Jack was the first nuclear submarine to make port at the newly opened submarine base in La Maddalena, Italy.  Jack conducted several special operations while in the Mediterranean and returned to New London on 21 January 1973.

From October 1975 to January 1977, the ship was given a major overhaul, including main engine overhaul and refueling, at the Portsmouth Naval Shipyard in Kittery, Maine. During sea trials in the North Atlantic, state six seas allowed a rush of seawater to travel down the induction mast, overflowing the induction sump and into the battery breaker room. This caused an explosion and fire. Several people were injured; according to HM1 Rodger Burdock, "one sonar tech had his ear drums totally sucked out by a bad valve line up for venting." Despite the accident, the ship passed sea trials and traveled to Groton, Connecticut. Continuing on to sound trials, mark 48 weapons certification, and various training missions during '77–'78, the ship suffered a main engine failure off the coast of North Carolina, and had to be towed back to Groton.

On 27 April 1981, Jack was moored alongside the amphibious transport dock USS Trenton (LPD-14) in heavy swells at Alexandria, Egypt, when she collided with Trenton. Both ships suffered slight damage.

Near the end of September 1982, Jack went to Portsmouth Naval Shipyard in Kittery, Maine for a 27-month overhaul. In April 1983, while in dry dock, she suffered a casualty. While conducting a hydrostatic test of the oxygen banks, the shipyard was using Freon (R-12) as the fluid to conduct the test (the Freon would leave no residue and potential contamination in the O2 banks upon evaporation after the test). One of the shipyard workers was unable to get out of the engineering space in time, and succumbed to the oxygen deprivation effects of the Freon and was not able to be revived.[1]
