1960s

With Newport, Rhode Island, designated as her home port, ''Koelsch'' spent the rest of 1967 at Boston, Massachusetts, much of it in drydock, fitting-out, workmen covering the teardrop-shaped sonar dome with an experimental rubber coating; installing the Antisubmarine Warfare Ship Command and Control System (ASWC&CS); replacing eight superheater tube stubs on 1A boiler; and removing the Drone Antisubmarine Helicopter (DASH) equipment in preparation for the ship's receiving a manned helicopter capability.

''Koelsch'' deployed on a Northern European-Mediterranean cruise, departing from Naval Station Newport on 20 August 1968 and returning on 19 December. During the deployment, she visited Southampton(United Kingdom, (UK) (3-9 September); Stavanger, Norway (11-16 September); Hamburg, Germany (1-7 October); Lisbon, Portugal (21-24 October); Naples, Italy (1-7 November); Barcelona, Spain (2-7 December); and Gibraltar (9-11 December).

From 14 January to 22 March 1969, ''Koelsch'' remained at Boston undergoing post-shakedown availability (PSA). On 1 April, she departed her home port for the Virginia Capes to conduct individual exercises and type training. On 1 May, ''Koelsch'' again departed Newport, refueling in the Azores, to join the antisubmarine warfare carrier s task group operating in the eastern Atlantic. All ships of the force anchored off Spithead, between Portsmouth (UK) and the Isle of Wright, on 14 May to be reviewed two days later by Queen Elizabeth II from the royal yacht HMY Britannia. After a five-day visit at Cherbourg, France, the destroyer escort rejoined ''Wasp'' on 22 May to conduct Hunter-Killer Group (HuKGru) operations and to evaluate the installed Antisubmarine Warfare Tactical Data System (ASWTDS) west of Ireland. ''Koelsch'' continued those operations until departing for Newport on 5 July, interrupted by port visits to Oslo, Norway (4-7 June) and Amsterdam, The Netherlands (23-30 June). The ship returned to Newport on 11 July, entering an upkeep period soon thereafter. She participated in operations Squeeze Play I (15-24 October) and Squeeze Play II (1-12 December), conducting ASW exercises off United States East Coast.

1970s

''Koelsch'' departed Newport on 5 February 1970 to participate in Squeeze Play III in the western Atlantic. She then conducted experimental ASW exercises and visited Bermuda twice (14–16 February and 22–23 February), before returning home on 2 March. On 13 April, she got underway for two weeks of independent exercises off the Virginia Capes punctuated by a liberty weekend at Naval Station Norfolk, Virginia (USA), which commenced on 17 April. The ship participated in Squeeze Play IV (18–28 May) and Squeeze Play V (8–21 June) off the east coast of the United States. Commander Cruiser-Destroyer Force, Atlantic (ComCruDesLant) awarded ''Koelsch'' the Rhode Island Navy League's Anti Submarine Warfare Trophy for her performance in the Squeeze Play evaluations, marking her as the outstanding ASW ship in the Atlantic Fleet.

''Koelsch'' and her crew attended the Maine Lobster Festival at Rockland, Maine (31 July – 3 August 1970) before acting on special orders during her return voyage to Newport, searching for and apprehending three enlisted people allegedly deserting to Canada in a pleasure craft, and turning them over to the Naval Criminal Investigative Service at Newport. The crew prepared their ship for a regular overhaul period by offloading ammunition at the Naval Weapons Station Earle, New Jersey, on 10 August and beginning a tender availability at Newport (21 August – 14 September).

Departing Palma on 14 January, the frigate suffered an engineering casualty the next day when a flareback in 1A boiler damaged 1A supercharger. The ship received an underway logistics replenishment from ''Butte'' on 19 January and returned to Las Palmas for five days before proceeding to Barcelona to replace 1A supercharger. ''Koelsch'' remained at Barcelona from 25 January to 15 February and then steamed to Naples, where she arrived on 18 February to begin preparations for operations in the Black Sea. Departing Naples on 1 March, the frigate conducted ASW line operations in the central Med before rendezvousing with guided missile cruiser ''Wainwright'' on 8 March and transiting the Turkish Straits into the Black Sea two days later. Following a week of exercises, ''Koelsch'' returned through the Bosphorus on 16 March and joined carrier in the eastern Mediterranean to provide escort service. The frigate returned to Naples on 26 March, and she departed the Italian port on 5 April to begin an ASW line period in the central Mediterranean. The ship entered an IMAV at Malaga, Spain (15-26 April), and while there received the Hook 'Em award for ASW excellence personally from Vice Admiral Frank B. Kelso III, Commander Sixth Fleet. Following a turnover with frigate , the ship departed Malaga on 26 April and arrived at Mayport on 7 May.

Following an NWAT visit (3-7 June 1985), ''Koelsch'' conducted a one-day sea trial on 10 June. The ship departed Mayport on 17 June to participate in ASW special operations in the western and mid-Atlantic for the remainder of the month. Breaking off from that work, the ship arrived at Bermuda on 3 July to conduct emergency repairs on 1B main feed pump and 1B boiler. Ordered home, the frigate arrived at Mayport on 7 July where she received two weeks of NWAT visits followed by passing the Navy Technical Proficiency Inspection (NTPI) on 25 July. After over two months in port, Hurricane Isabel forced ''Koelsch'' to sortie from Mayport, up the St. John's River, to Blount Island on 9 October, returning home the next day. Following successful sea trials (15-17 October), the ship received a series of inspections and reviews, after-which she steamed for Charleston to offload ammunition (20-21 November). Returning to Mayport on 22 November, the next day contractors began removing the AN/SQR-15 Towed Array Sonar System (TASS), completing the job on 27 November. ''Koelsch'' departed Mayport on 2 December to conduct drone services for the Guided Missile Hydrofoil Gunboat (PHM) Squadron 2, based at Key West, Florida. Exercises were conducted on 5 December, and the frigate departed Key West four days later, providing submarine support services in the Jacksonville area before returning to Mayport on 13 December.

''Koelsch'' conducted independent exercises in the Jacksonville area during January 1986, then assisted in search and rescue operations in the wake of the Space Shuttle Challenger disaster (28-31 January). Remaining at Mayport from 1 February to 12 March, the frigate passed a surprise NTPI (12-13 February). She completed an OPPE (24-25 March) and received a diesel inspection and auxiliary systems readiness review (31 March-4 April). Having offloaded ammunition on 3 April, ''Koelsch'' then entered a selective restricted availability (17 April-7 July). Following a training readiness evaluation (10-11 July), the ship conducted independent exercises in the Jacksonville operations area (14-16 July and 28–31 July). After a series of inspections and reviews, ''Koelsch'' got underway for Charleston on 26 August, onloading ammunition at the weapons station the next day. Stopping to refuel at Mayport on 29 August, the frigate spent 1 September to 17 October in refresher training at Guantanamo Bay, undergoing a rigorous schedule of training involving in-port and underway exercises. The ship and crew visited Grenada (24-26 October) and conducted NGFS exercises at Vieques (28-29 October) and ASW exercises with U.S. submarines at the AUTEC range, Andros Island, Bahamas (2-3 November). Embarking HSL-32, Detachment 9 on 26 November, the frigate got underway on 3 December for Roosevelt Roads, where members of the USCG Tactical Law Enforcement Team embarked for law enforcement operations (8-14 December) followed by a visit to Guantanamo Bay. She returned to Mayport on 20 December.

''Koelsch'' embarked HSL-32, Detachment 9 on 5 January 1987 and departed for Roosevelt Roads two days later, arriving on 10 January when five members of the United States Coast Guard team embarked again for law enforcement operations, during which time the ship investigated fifty-one motor vessels and pleasure craft in support of the Coast Guard's mission to stop drug transport in the area (11-30 January). On 13 January, the Coast Guardsmen operating from Koelsch discovered 18 kilograms of cocaine on board the Columbian-registered ''Granelero II'', and arrested all twenty of the crewmembers. After placing a prize crew on board the Columbian vessel, the frigate rendezvoused on the 15th with USCGC ''Nunivak'' (WPB-1306) and transferred the cocaine and prisoners, along with ''Granelero II'', to U.S. Federal authorities at San Juan, Puerto Rico. Following a visit to Antigua (2-4 February), the frigate returned to Mayport and entered an intermediate maintenance availability on 9 February that lasted until 12 March. ''Koelsch'' then hosted HMS Bristol (D23) during a British squadron's visit to Mayport (4-14 March). The U.S. frigate conducted a successful ASROC warshot proof test and two exercise torpedo shots in the local operations area (16-17 March). Embarking HSL-32, Detachment 9 on the 20th, she departed Mayport the next day to conduct her third law enforcement operation in four months. En route, the ship conducted a burial at sea service for CS1 William P. Wallace, USN (Ret.) off the Bahamas. Embarking a USCG team at Guantanamo Bay on 23 March, ''Koelsch'' conducted law enforcement operations until 12 April, investigating 112 motor vessels and pleasure craft for contraband during that time. On 23 March, the embarked helicopter detachment transported a civilian heart attack victim from , whose crew had recovered him from his sailboat, to the Guantanamo Bay Naval Hospital. On 1 April, three bags of marijuana were discovered floating in the water. After testing the contents for THC, they were destroyed. After disembarking the law enforcement team at Roosevelt Roads on the 12th, the ship visited St. Croix (14-18 April). Koelsch conducted NGFS qualifications and spotting services at Vieques (19-22 April), expending over 400 5-inch rounds.

Returning to Mayport on 25 April 1987, the frigate underwent several inspections and assist visits during May, along alteration of her major automatic boiler control system (28 April-6 May). Koelsch executed a highly successful defense nuclear surety inspection (1-2 June), receiving an overall grade of satisfactory with no discrepancies. On 7 to 12 June the Board of Inspection Survey (INSURV) inspected virtually every compartment and piece of equipment on board the ship. Although she received a satisfactory grade, and the INSURV found her fit for further service, but determined her not to be combat effective. From 15 June to 3 July, the frigate received installation of the SSQ-99 electronic support measures (ESM) van for use during Central American special operations in the eastern Pacific.

Following the embarkation of a Naval Security Group detachment, ''Koelsch'' got underway on 10 July 1987 for Naval Station Rodman, Panama to participate in special operations in the eastern Pacific Ocean. Stopping to refuel at Guantanamo Bay, the ship transited the Panama Canal on 15 July, putting into Rodman that evening. With a FIM-92 Stinger missile detachment embarked, the frigate conducted routine special operations (20-29 July), visiting Puerto Quetzal, Guatemala, until 1 August to refuel, re-provision, and conduct minor repairs. From 1 August to 7 October, ''Koelsch'' spent fifty-six days at sea conducting special operations in the eastern Pacific in support of Commander, Task Force (CTF) 84 and Joint Task Force (JTF) Bravo.

During that deployment, the ship made several good will visits to Central American ports. While the ship was in port at Rodman (10-13 August 1987), several crewmembers helped refurbish school desks and provide athletic equipment to a rural Panamanian elementary school. Later, several sailors delivered Project Handclasp food and medical supplies to an orphanage and street children's program in Guatemala City (22-25 August). During a visit to Puerto Quetzal (16-19 September) crewmembers painted an elementary school and delivered Handclasp materials in the area. With the conclusion of that stint of special operations, ''Koelsch'' put into Rodman before transiting the Panama Canal on the 10th.

During the ship's final visit to Rodman, however, members of the Panamanian Defense Forces arrested three ''Koelsch'' sailors, along with six United States Air Force people, falsely accusing them of anti-government activities. After 20 hours of detention, and following a strong formal protest by the U.S. government, the Panamanians released the nine Americans but required them to remain in Panama to attend a hearing. The three sailors later rejoined their ship at New Orleans. Meanwhile, the ship anchored at Montego Bay, Jamaica, on 12 October for three days of liberty. After a stop at Guantanamo Bay on the 16th, ''Koelsch'' arrived at New Orleans on 21 October to participate in the Navy League's Fleet Week, supporting the visit of the Commander in Chief, U.S. Atlantic Fleet, and hosting over 3,200 visitors. The ship departed New Orleans on the 26th with 60 guests embarked for a "Tiger Cruise," that ended when the ship reached Mayport on 29 October.

Koelsch began a two-month IMAV on 2 November 1987, interrupted by a visit to Charleston on 10 December to offload ammunition in preparation for a regular overhaul at Bath Iron Works), Portland, Maine. Completing the IMAV on 31 December 1987, the frigate departed Mayport on 4 January 1988 and arrived at Portland three days later. Work on the ship proceeded at an irregular pace, however, due to uncertainty about her final status. CinCLantFlt issued a stop work order to Bath Iron Works on 28 January 1988 to limit the cost of the overhaul after announcing the proposed decommissioning of all ''Garcia''-class frigates. Work resumed on 25 February, but the uncertainty regarding the ship's future dampened the spirits of both shipyard workers and crew. Lack of funding forced cancellation of some overhaul work including major repairs to the sonar dome, replacement of the forward 5-inch gun mount, and a full overhaul of the Naval Tactical Data System (NTDS) equipment.

On 21 March 1988, the United States Department of Defense announced that ''Garcia''- and ''Brooke''-class frigates would be mothballed or made available for foreign military sales. On 16 April, the Chief of Naval Operations ordered that the ship be in a "fully functional condition" at the end of the overhaul, but continued ambiguity resulted in Bath Iron Works' falling further and further behind schedule. ComNavSurfLant recommended ''Koelsch'' for foreign military sale on 30 April, and on 20 May defined the term "fully functional" to provide guidance for the work. Nevertheless, a management change and low manning at BIW put work on the ship six weeks behind the revised schedule by the end of July. Negotiations led to a revised contract with a completion date of 3 February 1989.

On 18 August 1988, it was announced that ''Koelsch'' was a primary candidate for lease by Pakistan. Although the date would be revised, on 22 September ComNavSurfLant directed that the frigate be decommissioned at Charleston on 27 March 1989 with a "hot ship" turnover to the Pakistani Navy. Bath Iron Works increased worker manning level to 140% of that planned on 9 October, but delays in the U.S. President's signature on the foreign military sales case delayed the decommissioning date to 31 May.

Despite a contractual impasse in January 1989, BIW completed Koelsch's ROH on 28 February. On that day, the ship departed Portland for Charleston, where she arrived on 3 March. The ship began the official decommissioning stand-down on 7 March. All NTDS equipment was laid up pending Pakistan Navy sailors qualifying technicians to maintain it. On 16 March, the crew removed or destroyed all cryptographic equipment and installed bypass cables to increase the number of non-secure voice circuits. All Chemical, Biological, and Radiological (CBR) equipment was removed from the ship and all unneeded classified documents destroyed. The Pakistani Navy completed the training plan on 24 March, covering all areas of shipboard operation and maintenance, with particular attention to engineering watch-standing to ensure the safe steaming of the ship to Karachi. All satellite communications and SITE-TV equipment were removed on 28 and 29 March. Test equipment, spare parts, and technical manuals were removed on 11 April and turned in to Defense Reutilization Management Office. The Pakistani crew arrived on board the ship in thirds on 15, 24, and 28 April. Engineering cold plant and damage control training began the week of the 17th, and the crew lit off the engineering plant and continued training the Pakistani crewmen on 24 April. Koelsch got underway on 9 May to give three days of hands-on training in every operational area of the ship. The Pakistan Navy crew participated fully in all evaluations ranging from cold checks prior to light-off through general quarters, conducting a main space fire drill and gun shoot. All engineering, weapons, and operations sailors stood watch and operated all equipment under the supervision of U.S. crewmen. In the same manner, from 16 to 18 May, ''Koelsch'' sailors trained the Pakistani crew of Hunain (ex-). ''Koelsch''s crew held their final picnic on 21 May and their final awards ceremony on 26 May.

Navy of Pakistan

Decommissioned on 31 May 1989 at Charleston, Koelsch was transferred to the Pakistani Navy on the same day under the terms of a five-year lease agreement. She was recommissioned as Siqqat (F-267).

Fate

Because Pakistan would not stop its nuclear weapons program, the lease was cancelled in 1994. Returned to U.S. custody at Singapore on 19 August 1994, former ''Koelsch'' was stricken from the Navy Register the same day. Transferred to the Maritime Administration the following 9 September, on the same date she was sold to Trusha Investments Pte. Ltd, c/o Jacques Pierot, Jr. & Sons, Inc., of New York City for $625,824. She was then towed to Hong Kong and scrapped.

Namesake

''Koelsch'' was named for Navy helicopter pilot Lt(jg) John Kelvin Koelsch, who was awarded the Medal of Honor for actions during the Korean War. On 3 July 1951, Koelsch and his crewman attempted to rescue a downed Marine aviator from enemy territory. Under heavy fire, Koelsch's helicopter was shot down; Koelsch, his crewman, and the Marine aviator survived the crash and evaded the enemy for nine days before being captured. Lt(jg) John Koelsch died of malnutrition and dysentery in a prisoner-of-war camp three months later.

Insignia

The dominant figure of the insignia is the chess knight, a most mobile and versatile piece, that is a fitting symbol of a mobile and versatile ocean escort. The blue ribbon with white stars in the background symbolizes the Medal of Honor earned by Lt. (j.g.) Koelsch, while a prisoner of war in Korea. The emblem and the ship's name and motto are enclosed in a double line with two square knots, the double line symbolizing the unit of the service and square knots symbolizing the strength of the service. The black knight represents strength of convictions; blue, the sea; and white, the purity of purpose. The ships motto was "Valor ndVersatility."
