Service history

1971–1973 Early in December, the destroyer escort sailed for her home port, Norfolk, Virginia, and arrived there on 10 December. After spending the holidays in port, Aylwin headed for Guantánamo Bay, Cuba, for shakedown training. While en roue, Aylwin stopped at Andros Island, Bahamas, for weapons testing. Arriving at Guantánamo Bay on 24 January 1972, the ship began four weeks of intensive training. She visited Santo Domingo for a liberty call before returning to Norfolk for post-shakedown availability. Late in October, the vessel participated in LAN-TREDEX 2-72 and then made final preparations for her first overseas deployment. On 1 December, Aylwin departed Norfolk to join the 6th Fleet in the Mediterranean. Her first stop was at El Ferrol, Spain. Departing that port on 13 December, she transited the Strait of Gibraltar and proceeded to Athens, Greece, where she spent the holiday season.

On 6 January 1973, Aylwin got underway for antisubmarine warfare (ASW) operations to be held in the eastern Mediterranean in conjunction with Task Force (TF) 60. The ship pulled into Golfe-Juan, France, on 17 January, then continued on to Gibraltar. Next came ASW operations in the eastern Mediterranean followed by a visit to Naples, Italy, for a two-week tender availability. The destroyer escort then visited Dubrovnik, Yugoslavia. On 17 February, she participated in NATO Exercise "National Week," held in conjunction with British, Italian, and Turkish warships. She arrived at Alanya, Turkey, on 28 February and then stopped at Athens; La Maddalena, Italy; Alicante, Barcelona, and Valencia, Spain; Tunis, Tunisia; Villefranche, Cannes, and Toulon, France; and Gibraltar. On 20 June, Aylwin got underway once more for the United States. She paused at the Naval Weapons Station, Yorktown, Virginia, on 27 June, to unload her weapons and returned to Norfolk the next day ending an absence of seven months. The ship was dry-docked from 19 July to 20 August. She received the light air multi-purpose system (LAMPS) modification during a yard period lasting through 26 October. A tender availability came in November, and December found the ship in a stand-down period.

1974–1975 The Destroyer Escort sailed on 19 February 1974 for refresher training at Guantánamo Bay. While there, she took part in ASW exercises in addition to testing her new LAMPS equipment. She returned to Norfolk on 27 April to make final preparations for her second overseas deployment. On 17 June, Aylwin set sail for the Mideast and the Indian Ocean. Her first stop was Roosevelt Roads, Puerto Rico, where she held gunnery exercises. She then proceeded to Trinidad & Tobago for a refueling stop. Aylwin next put into Recife, Brazil, for a brief liberty period.

She got underway again on the 28th to cross the Atlantic and arrived at Freetown, Sierra Leone, on 2 July. Aylwin's next stop was Luanda, Angola. Her visit there was curtailed by an outbreak of violence associated with that country's bid for independence from Portugal. The vessel weighed anchor on 13 July, sailed around the Cape of Good Hope, and entered the Indian Ocean. Aylwin arrived in Port Louis, Mauritius, on 26 July, and continued on to Reunion Island on 31 July. Her next stop was Moroni, Great Comoro Island. On 6 August, she arrived at Mombasa, Kenya. The destroyer escort got underway again on the 17th and spent the next two months patrolling the Gulf of Aden, the Red Sea, and the Persian Gulf. She made brief stops at Djibouti, Afars and Issas; Muscat, Oman; Bahrain; Bandar Abbas, Iran; and Massawa, and Asab, Ethiopia.

After final calls at Mombasa and Port Louis, Aylwin sailed on 8 November to return to the United States. She retraced her earlier course and made stops at Luanda, Angola, Recife, Brazil, and Roosevelt Roads before reaching Norfolk on 13 December.

1975–1976 The ship returned to sea in mid-February 1975 with a series of exercises in the Virginia capes area. On 17 March, she sailed from Norfolk, bound for the Narragansett Bay operating area to conduct a LAMPS test. During the cruise, she visited New York City and Albany, N.Y., before returning to Norfolk on 28 March. The next two months were occupied by a series of inspections. On 12 June, Aylwin sailed for Newport, R.I., to conduct a midshipman training cruise. While on this assignment, Aylwin was officially reclassified a frigate and redesignated FF-1081 on 1 July. She returned to Norfolk on 3 July. The ship sailed on 7 August for Guantánamo Bay and the fleet exercise CARIBEX. The next day, she experienced mechanical difficulties and proceeded to the Charleston Naval Shipyard for repairs. After two more attempts to sail to the Caribbean, Aylwin turned back to Norfolk on 27 August. After a month of repairs and preparations, the frigate sailed on 3 October for the Mediterranean. She reached Rota, Spain, on 13 October and was scheduled to take part in exercises. However, a boiler problem necessitated a run to Naples, Italy, for a two-week availability alongside tender . With the repairs completed, Aylwin set sail for Toulon, France, on 2 November to join NATO forces in Exercise "Isle d'Or." Following this operation, Aylwin arrived in Palermo, Sicily, on 20 November. Additional visits were made at Athens, Greece; Souda Bay, Crete; and Kusadasi, Turkey. Aylwin returned to Naples on 22 December 1975 for the Christmas holidays.

On 7 January 1976, Aylwin got underway with Task Group (TG) 60.1 for ASW exercises. She then sailed to the ports of Piraeus, Greece; Souda Bay; Bodrum, Turkey; Catania, Sicily; Valencia, Spain; Palma, Majorca; and Gaeta and Genoa, Italy. Aylwin briefly stopped once again at Rota on 17 April, then left the Mediterranean, bound for Norfolk where she spent May and early June in leave and upkeep. A week of ASW exercises came in mid-June. On 26 July, Aylwin proceeded to Philadelphia, Pennsylvania, where she entered drydock at the naval shipyard on 8 August for overhaul.

1977–1978 The frigate departed Philadelphia on 6 June 1977 and steamed to her new home port, Charleston, S.C. There, she became a unit of Destroyer Squadron 20. During the next six weeks, Aylwin conducted local operations; and, on 18 July, she headed for the Caribbean and refresher training. She was back in Charleston on 20 September and spent the rest of the year in training exercises and inspections.

Aylwin put to sea on 3 January 1978 to provide submarines and services as a target as they sharpened their hunting skills. The next day, she was directed to proceed to the Key West, Florida, area to conduct surveillance operations and relieve destroyer . She finished these duties on 10 January and arrived back at Charleston on the 11th. The next three months were devoted to local operations and preparations for overseas movement. Aylwin rendezvoused with other units of Cruiser-Destroyer Group 12 off Bermuda on 7 April and sailed across the Atlantic to Malaga, Spain. A series of ASW exercises followed; and, on 29 April, the frigate moored alongside tender at La Maddalena, Sardinia, for an availability. On 14 May, Aylwin put to sea, bound for Souda Bay. There, she joined NATO forces for Exercise "Dawn Patrol". Following that operation, the ship anchored at Skiathos, Greece, on 1 June. Her other ports of call during the cruise were Barcelona, Spain; Golfo di Palmas, Sardinia; St. Tropez France, Alexandria, Egypt, Haifa, Israel, Piraeus, Greece, Palma, Mallorca and Toulon, France. The last exercise of the deployment was Exercise "Display Determination," which lasted from 26 September to 8 October. Following a final stop at Malaga, Aylwin set sail on 14 October for Charleston. She arrived at her home port 11 days later and spent the remainder of 1978 there undergoing upkeep.

1979 The ship devoted January and February 1979 to training and inspection and, on 26 February, began a restricted availability. She got underway again on 6 April for a dependents' cruise and, 10 days later, proceeded to Puerto Rico for refresher training. From 1 to 8 May, Aylwin took part in SUBASWEX 3-79. After completing this exercise, she sailed to New York City for the celebration of Armed Forces Week. The frigate returned to Charleston late in May and commenced a series of tests and inspections prior to beginning her next overseas deployment.

On 1 August, Aylwin got underway for another Mideast cruise. She made refueling stops at Bermuda and Ponta del Gada before reaching Rota on 11 August. From Rota, she headed to Malaga and then continued eastward. She passed through the Suez Canal on 19 August and arrived in Jidda, Saudi Arabia, on the 22nd. She moved south on 1 September to the Gulf of Aden, thence steamed around the Arabian peninsula and through the Strait of Hormuz to reach Bahrain. The frigate got underway on the 4th to operate in the Persian Gulf and pulled into Dammam, Saudi Arabia, on 16 September for two days of liberty. Aylwin took part in a joint exercise with Saudi forces, then stopped at Bahrain for refueling. She proceeded to the Seychelles Islands on 8 October, but her stay was shortened by civil unrest. On 13 October, Aylwin sailed for Djibouti. From there, she headed into the Gulf of Aden to conduct an exercise with warships of the French Navy on 22 October.

Aylwin steamed eastward and then north around the Arabian peninsula to pass through the Strait of Hormuz, where she participated in an exercise with naval forces from Oman. The frigate then sailed to Bahrain for a two-week upkeep period. That respite ended abruptly on 4 November when she got underway only two hours after learning that militant Iranian students had stormed into the United States embassy in Tehran and made captives of American diplomatic and military personnel. The frigate headed back into the Persian Gulf for surveillance and patrol duties that lasted until 9 December. On that day, Aylwin began the long voyage home. She paused at Djibouti to refuel, then sailed north, transited the Suez Canal, and continued across the Mediterranean to Rota, Spain, where she arrived on 23 December. After celebrating Christmas in that Spanish port, Aylwin sailed for Charleston on 28 December 1979. Following a stormy Atlantic crossing, she stood into Charleston, S.C., on 7 January 1980.

1980–1982 The frigate completed post-deployment stand-down on 6 February and spent the next two weeks making minor repairs. On the 19th, Aylwin returned to sea to conduct drills with Atlantic Fleet submarines. She carried out such routine training missions along the eastern seaboard until the end of April. On the 28th, the warship departed Charleston and set course for Brooklyn, N.Y., where she entered the yard at the Coastal Drydock & Repair Corp. for a major overhaul. The repairs – which included major work to her main propulsion plant, a period in drydock, and many lesser modifications – lasted a year almost exactly. She conducted sea trials on 29 and 30 April 1981 and returned to Charleston on 3 May 1981.
