She was built to clear minefields in offshore waters, and served the Navy in the North Atlantic Ocean and then in the Pacific Ocean. She returned home, finishing the war with two battle stars to her credit. When she was recalled for duty in the Korean War, she returned home again with four more battle stars.

History

[edit]

Incredible was launched 21 November 1943 by Savannah Machine & Foundry Co., Savannah, Georgia; sponsored by Mrs. Herbert Hezlep; and commissioned 17 April 1944.

World War II

[edit]

After shakedown along the U.S. East Coast and in the Caribbean, Incredible departed Norfolk, Virginia, 24 July, escorting a convoy to North Africa for the invasion of southern France, the Allies landing 15 August. She carried out her sweeping duties very effectively, sometimes without destroyer cover. On 10 September Incredible and her group repelled an attack of 12 human torpedoes, 2 of which she destroyed. She continued her minesweeping duties off southern France until 18 January 1945 when she sailed for a special mission to Russia and the Black Sea. Incredible performed sweeping duties out of Sevastopol, Russia, then served as an air-sea rescue patrol ship in the Black Sea until resuming to Palermo, Sicily, 20 February.

Incredible returned to Norfolk 5 May; and, after overhaul, departed 23 July for duty in the Pacific. She arrived Pearl Harbor eight days after the fighting stopped via the Panama Canal Zone and San Diego, California. The minesweeper sailed from Pearl Harbor 31 August for Operation Skagway, clearing the minefields in the East China Sea-Ryukyus area. This important duty lasted until 17 February 1946 when she returned to San Pedro, Los Angeles. She remained there until she decommissioned at Puget Sound 6 November, joining the Reserve Fleet. From 28 November 1947 to 28 September 1949 Incredible was "In Service, out of commission", based at Yokosuka, Japan.

Among her crew was Lee Van Cleef, who after the war became an actor known for his roles in Spaghetti Westerns. Van Cleef served on the USS Incredible from 1944-1946 and won a Bronze Star when this ship was attacked after Operation Dragoon on September 10, 1944.

Korean War operations

[edit]

Incredible was recommissioned 14 August 1950 at Yokosuka and departed 18 September for minesweeping and patrol duties in the Pusan area. While on patrol in mine-infested waters, on 12 October she rescued 27 survivors from USS Pirate (AM-275) which had struck a mine. Delivering her passengers to safety, she continued her operations in the battle zone, sweeping harbors and serving on patrol and escort duty. Returning to Yokosuka, Japan, Incredible sailed for Long Beach, California, arriving 4 August 1951.

The minesweeper operated along the U.S. West Coast and out of Pearl Harbor until 6 August 1953 when she sailed for the Far East. For the remainder of the year she operated out of Japan and on patrol along the coast of Korea

Incredible returned to Long Beach 11 March 1954 and was decommissioned there 21 September, again joining the Reserve Fleet. Reclassified MSF-249, 7 February 1955, Incredible remained in the Long Beach Group, Pacific Reserve Fleet until she was struck from the Navy List 1 December 1959. She was sold 8 August 1960 to National Metal and Steel Corp., Terminal Island, California.

Design and description

General characteristics

The USS Incredible (AM-249) was a steel-hulled vessel of the Admirable class, designed primarily for coastal and ocean operations during and after . As part of this prolific class, she featured a compact yet robust construction optimized for versatility in hazardous waters, with dimensions and propulsion systems that balanced maneuverability, endurance, and payload capacity for mine countermeasures. Her classification as an Admirable-class was later updated to fleet ocean minesweeper (MSF-249) on 7 February 1955, reflecting postwar adaptations for expanded roles in mine clearance. Key physical specifications included a standard displacement of 625 tons and 945 tons at full load, enabling her to carry essential equipment while maintaining stability in rough seas. The ship's overall measured 184 feet 6 inches, with a beam of 33 feet and a draft of 9 feet 9 inches, allowing access to shallow coastal areas prone to mining threats. These proportions contributed to her agility during sweeping operations.
CharacteristicSpecification
Displacement (standard/full load)625 tons / 945 tons
184 ft 6 in (56.24 m)
Beam33 ft (10 m)
Draft9 ft 9 in (2.97 m)
Propulsion was provided by two Cooper-Bessemer GSB-8 diesel engines delivering a total of 1,710 shaft horsepower to twin shafts, achieving a maximum speed of 15 knots and a range of 4,300 nautical miles at 9 knots. This diesel configuration offered reliable, low-maintenance power suitable for extended patrols, with fuel efficiency prioritized over high-speed performance. The crew complement consisted of 104 officers and enlisted men, sufficient to manage operations across multiple shifts. For mine detection and clearance, Incredible was fitted with two QD-type sonars for echo location, alongside standard magnetic and acoustic mine-sweeping gear, including paravanes and sweep wires to trigger or deflect mines. The hull design facilitated seamless integration of these sensors with armament mounts, ensuring minimal interference during active sweeping.

Armament and sensors

The USS Incredible (AM-249), as an Admirable-class minesweeper, was equipped with a primary for surface and anti-aircraft fire, consisting of one mount forward. This weapon provided the ship's main offensive capability against surface threats and low-flying aircraft during escort and patrol duties. For anti-aircraft defense, Incredible carried two twin 40 mm mounts and six single 20 mm Oerlikon mounts, distributed along the deck to cover multiple arcs and protect against air attacks common in minefield operations. These automatic cannons were standard for the class, enabling rapid fire to deter bombers or fighters. In its role, the ship featured one forward-throwing anti-submarine mortar, capable of launching a pattern of 24 projectiles ahead to attack submerged submarines without breaking contact. Complementing this were four K-guns (depth charge projectors) for launching charges to , along with two depth charge tracks aft for rolling charges into the water, forming a typical WWII ASW pattern. Minesweeping operations relied on specialized gear including paravanes towed from the bows to deflect and cut mooring wires of contact mines, sweep wires for mechanical clearance, and cutters designed for severing cables. The class also supported magnetic sweeps using electromagnetic coils to detonate influence mines and acoustic sweeps with noisemakers to trigger sound-sensitive types, allowing Incredible to clear paths for larger naval forces. Sensors included two QDA sonars for depth determination and mine detection, aiding in through hazardous waters and locating submerged threats. These echo-ranging systems operated in the 50-60 kHz band, providing essential data for precise sweeper positioning. Throughout its service, Incredible retained the standard Admirable-class configuration with no major armament or modifications recorded.

Construction and commissioning

Construction

The USS Incredible (AM-249), an Admirable-class minesweeper, was constructed by the Savannah Machine and Foundry Company in Savannah, Georgia, under a contract awarded on 2 May 1942 as part of the United States Navy's World War II emergency shipbuilding program to rapidly expand the fleet of coastal minesweepers. Her keel was laid down on 9 September 1943, initiating the assembly of her wooden hull designed for non-magnetic minesweeping operations. Construction proceeded swiftly in line with wartime priorities, with the ship launched just over two months later on 21 November 1943; the ceremony was sponsored by Mrs. Herbert Hezlep. During this phase, workers fitted the vessel with the standard hull form, including reinforced internal compartments for buoyancy and equipment storage, reflecting the Admirable-class design optimized for agility in mine clearance tasks.

Shakedown and commissioning

Following her launch, USS Incredible (AM-249) underwent final outfitting before being commissioned on 17 April 1944, with Lieutenant R. N. Ekland, USNR, assuming command. The ceremony marked the ship's official entry into the U.S. Navy, where standard armament was fitted during this phase to prepare her for duties. The newly commissioned vessel then embarked on a along the East Coast and into the , allowing the crew to test systems, sensors, and equipment under operational conditions. This phase included acceptance trials featuring speed runs to verify maximum capabilities, maneuverability assessments in varied sea states, and calibration of onboard gear, all completed by mid-1944 to ensure readiness. Initial crew training occurred concurrently during the shakedown, familiarizing personnel with the ship's systems and procedures prior to active service. Upon successful completion, Incredible was assigned to the Mine Force, Atlantic Fleet, reflecting her role as an Admirable-class . She departed , on 24 July 1944, bound for her first operational assignment.

Service history

World War II operations

Following her shakedown cruise along the East Coast and in the Caribbean, USS Incredible (AM-249) departed Norfolk, Virginia, on 24 July 1944, to escort a convoy bound for North Africa in support of Operation Dragoon, the Allied invasion of southern France. In the ensuing weeks, Incredible shifted to minesweeping duties off the southern French coast, clearing naval minefields to secure the invasion beaches and adjacent waters. On 10 September 1944, while operating without destroyer escort, the minesweeper detected and engaged a group of 12 human torpedoes (Italian maiali or similar manned submersibles) approaching Allied forces; using depth charges and 3-inch gunfire from her standard armament, Incredible successfully repelled the attack and destroyed two of the threats. These operations continued effectively through the fall of 1944, aiding the consolidation of the beachhead. From 18 January to 20 February 1945, Incredible transited to the , basing out of in the to conduct in support of Allied logistics and operations in the region. In addition to clearing minefields, she performed patrols to assist downed aviators and distressed vessels. Upon completion, the ship returned to , , on 20 February 1945, before proceeding to , arriving on 5 May 1945. Incredible arrived in on 5 May 1945, shortly after the European theater's victory. On 23 July 1945, she departed again, transiting the and calling at en route to , where she arrived just eight days after the announcement of Japan's surrender on 15 August 1945.

Postwar minesweeping and reserve

Following the end of , USS Incredible (AM-249) participated in Operation Skagway, a critical postwar effort to clear naval minefields laid during the conflict. Departing on 31 August 1945, the ship operated in the and , systematically sweeping areas to establish safe shipping lanes for Allied vessels and commercial traffic. This operation, which employed established World War II-era magnetic and acoustic sweeping techniques, continued until 17 February 1946, when Incredible returned to San Pedro, California. She remained there until she decommissioned at on 6 November 1946 and joined the . From 28 November 1947 to 28 September 1949, Incredible was placed "in service, out of commission" and based at , .

Korean War operations

Following the outbreak of the , USS Incredible (AM-249) was reactivated from the reserve fleet and recommissioned on 14 August 1950 at , . She departed for operational duties on 18 September 1950, arriving in the Pusan area to commence patrol and minesweeping missions in support of forces. In October 1950, Incredible participated in critical operations in Harbor, clearing North Korean mines to facilitate amphibious landings and naval support. On 12 October 1950, during these efforts off , she rescued 27 survivors from the USS Pirate (AM-275), which had struck a mine and sunk, with Incredible serving as a key vessel in the formation conducting the sweep. Incredible continued extensive along the Korean coast through 1951, operating in mine-infested waters to clear harbors, conduct patrols, and provide escort duties for UN naval operations. She returned to the , arriving at , on 4 August 1951 for overhaul and further preparations.

Final deployment and decommissioning

Following the of July 1953, USS Incredible (AM-249) embarked on her third and final deployment to the , departing Long Beach on 6 August 1953 for patrol duties off the coasts of and Korea to support enforcement of the . Operating primarily out of bases in , the ship conducted routine patrols along the Korean coast through the remainder of 1953, ensuring compliance with armistice terms amid lingering tensions in the region. The vessel returned to Long Beach on 11 March 1954 after completing her deployment, marking the end of her active operational service. She was decommissioned there on 21 September 1954 and placed in the at Long Beach, where she remained inactive for the duration of her reserve period. On 7 February 1955, Incredible was reclassified as a fleet (MSF-249) while in reserve status, reflecting broader reorganizations in antisubmarine and mine warfare capabilities. She was struck from the on 1 December 1959, after which she was sold for scrap on 8 August 1960 to the National Metal and Steel Corporation, ending her naval career without any further reactivation.
