The Auk class were a class of minesweepers serving with the United States Navy and the Royal Navy during World War II. In total, there were 93 Auks built.

Design and development

Prior to the United States entering World War II, they had produced two ships of the Raven-class minesweeper for testing and evaluation. From these two examples it was decided that the use of diesel-electric engines to power the ship and the minesweeping equipment, rather than separate geared diesel engines to propel the ship and diesel generators to energize the minesweeping equipment, would work better. The Royal Navy placed an order for 32 of these minesweepers from the United States, BAM-1-BAM-32. Because of the additional equipment, the displacement was raised from 810 long tons (820  t ) on the Ravens, to 890 long tons (900 t) on what would come to be known as the Auk class in the USN, and the Catherine class in the RN. [1]

The Auk class displaced 890 long tons, with a length of 221 ft 1 in (67.39 m), a beam of 32 ft 2 in (9.80 m), and a draft of 10 ft 9 in (3.28 m). They had a maximum speed of 18.1  kn (33.5 km/h; 20.8 mph). The Auks armament varied. All were equipped with a single 3-inch (76 mm) gun on the bow, but many had their aft 3-inch gun removed or replace by two 40 mm (1.57 in) Bofors guns. Originally designed with four 20 mm (0.79 in) Oerlikon cannons, some ships mounted as many as eight. [2]

Five manufactures provided the diesel-electric engines used in the class. These included the Cleveland Diesel Engine Division of General Motors, Cooper Bessemer, Baldwin Locomotive Works, the American Locomotive Company (ALCO), and Busch-Sulzer. [3]

Twenty of the original 32 ships ordered by the Royal Navy were delivered, with an additional two coming from the USN program. They were given "J" pennant number prefixes. Of these twenty-two, three were sunk in action, and 19 were returned to the US after the war. [4]

Eleven minesweepers of the Auk class were lost in World War II, six to direct enemy action including USS Skill, torpedoed by U-593. [4]

Construction

The ships were constructed in 11 different shipyards, by 10 different companies, in 9 different states. [5]

<i>Admirable</i>-class minesweeper Class of United States Navy minesweeper ships

The Admirable class was one of the largest and most successful classes of minesweepers ordered by the United States Navy during World War II. Typically, minesweepers detected and removed naval mines before the rest of the fleet arrived, thereby ensuring safe passage for the larger ships. They were also charged with anti-submarine warfare (ASW) duties with rear-mounted depth charge racks and a forward-firing Hedgehog antisubmarine mortar. Their job was essential to the safety and success of U.S. naval operations during World War II and the Korean War. These minesweepers were also employed as patrol vessel and convoy escorts. The only remaining ship of this class is located at Freedom Park, Omaha, NE.

<i>PCE-842</i>-class patrol craft United States Navy ship class of submarine chasers

The PCE-842-class patrol craft escort was a United States Navy (USN) ship class of submarine chasers designed during World War II. The PCE-842-class was the only class ever designated by the USN as the "patrol craft escort" (PCE) type. The PCE design was derived from the 180-foot (55 m) Admirable-class minesweeper to complement the 173-foot (53 m) PC-461-class submarine chasers that were used for anti-submarine warfare (ASW) in coastal areas. At 185 feet long and 640 tons, the PCE is more than twice the displacement of the PC but with a less powerful engine also much slower; however, because of its larger size, the PCE was able to undertake longer-range tasks over PC-461-class vessels. The USN envisaged the PCE as enabling PCs and smaller vessels to undertake coastal patrols without being called-upon as often to perform open ocean and convoy escort duties, while simultaneously freeing-up some larger vessels - such as destroyer escorts and destroyers - from convoy ASW duties. The PCE-482-class had a standard crew complement of 99 officers and men. The class would ultimately see 68 total vessels built, serving with multiple navies around the world.
