In addition, she participated in a number of rescue experiments for the Bureau of Ships, testing diving bells, submarine buoys, ground tackle, mooring gear, and related equipment.

Her most significant contribution during those six years came in January 1950 when Missouri (BB-63) ran aground in the vicinity of Thimble Shoals Light and Old Point Comfort, Hampton Roads, Virginia.

En route to Scotland, Tringa made a brief side trip to Newfoundland to deliver a critically ill Fulton crewman to the naval hospital at Argentia.

At Le Havre, she provided tender services for the submarines returning from the exercises until 11 October when she headed home toward the United States.

Tringa reentered Newport on 23 October and, after three weeks of upkeep, sailed for Bermuda and another tour of duty with the submarine Prospective Commanding Officers' School.

She underwent her biennial overhaul at Boston that spring and, after refresher training in June, made a two-week goodwill cruise to Canadian ports in July.

Tringa returned to New London on 22 July and, through the first month and a half of 1959, trained divers, served as target and torpedo recovery ship for New London-based submarines, and conducted drills.

In January 1960, she conducted diving operations in Narragansett Bay with a group of four Norfolk-based minesweepers in a search for debris from an exploded aircraft.

Following the annual "Springboard" exercise in mid-February, Tringa visited Puerto Rico, the Virgin Islands, and the Dominican Republic before resuming duty out of New London late in March.

In the fall, she steamed south to Florida but remained in southern waters only briefly — assisting the Bureau of Weapons in tests — before the requirements of the FBM program called her back to New London.

At Holy Loch, Scotland she picked up an APL and a YRDM for tandem tow to the United States and departed the British Isles on 12 August.

Normal operations and escort duty for two newly constructed FBM submarines — Nathan Hale (SSBN-623) and Lafayette (SSBN-616) — occupied the ship for the remainder of the year.

Three days out of port, the ship was ordered to the Mediterranean to join in the search for the nuclear weapon missing after the mid-air collision of a B-52 bomber with a KC-135 tanker aircraft.

Upon her arrival off Palomares, Spain, Tringa was fitted out with underwater television equipment with which she conducted visual inspections of sonar contacts while her divers assisted in the recovery.

Local operations out of New London occupied her time until the end of September when she entered the James S. Munro Shipyard at Chelsea, Massachusetts, for overhaul.

A little over two months later, the ship resumed operations from New London and remained so occupied until the end of November when she entered the Boston Naval Shipyard.

She reported to her new home port on 29 April; and, for the rest of the year, she operated in the Gulf of Mexico and along the southeastern coast of the United States.

Upon her return to the United States on each occasion, she resumed her duties at Key West conducting torpedo exercises with Atlantic Fleet submarines.

In June 1973, Tringa rushed to the rescue when Johnson Sea Link accident disaster struck a civilian deep-submergence vehicle test project.

Tringa made a four-point moor above the stricken craft and for two days provided a platform for divers engaged in the rescue operation.

The following month, Tringa was reassigned to New London, and spent August and September engaged in the familiar role of standby rescue and target recovery ship for New London-based submarines.

The ship departed the western Atlantic only once during that period, in July 1975, to participate in a series of oceanographic surveys conducted from the submarine base at Holy Loch, Scotland.
