USS K-2 (SS-33)

USS Cachalot/K-2 (SS-33), also known as "Submarine No. 33", was a K-class submarine, of the United States Navy (USN). Originally named Cachalot, she was the first ship in the USN to be named for the cachalot, though she was renamed K-2 before being laid down. She patrolled off the Azores, during World War I.

The K-class boats had a length of 153 ft 7 in (46.8 m), a beam of 16 ft 8 in (5.1 m), and a mean draft of 13 ft 1 in (4.0 m). They displaced 451 long tons (458 t), on the surface, and 527 long tons (535 t) submerged. They had a diving depth of 200 feet (61.0 m). The K-class submarines had a crew of 2 officers and 26 enlisted men.

For surface running, the boats were powered by two 475-brake-horsepower (354 kW) NELSECO diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 170-horsepower (127 kW) electric motor. They could reach 14 kn (26 km/h; 16 mph) on the surface and 10.5 kn (19.4 km/h; 12.1 mph) underwater. On the surface, the boats had a range of 3,150 nmi (5,830 km; 3,620 mi) at 11 kn (20 km/h; 13 mph) and 120 nmi (220 km; 140 mi) at 5 knots (9.3 km/h; 5.8 mph) submerged.

The K-class submarines were armed with four 18 inch (450 mm) torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes.

K-2's keel was laid down on 20 February 1912, by the Fore River Shipbuilding Company in Quincy, Massachusetts, as a subcontract for the Electric Boat Company. Her name had changed from Cachalot, on 17 November 1911, she was the first US Navy ship named for the cachalot, another name for the sperm whale. She was launched on 4 October 1913, sponsored by Miss Ruth Chamberlain McEntee, and commissioned on 31 January 1914.

K-2 was initially assigned to the 3rd Division, Submarine Flotilla, Torpedo Flotilla, Atlantic Fleet, as of 2 February 1914.

The batteries in the submarine failed just two months after the sea trial and Rear Admiral William Nelson Little was court-martialed for accepting the submarine, even after problems with the batteries were recognized.

The submarine got underway and cleared the Boston Navy Yard, on 5 June 1914, and reached the New York Navy Yard, Brooklyn, New York, the following day, whereupon she drydocked for overhaul. With her work completed, she cleared the yard, on 4 July, and proceeded north to Newport, Rhode Island. Getting underway on 28 July, she shuttled to Buzzard's Bay, Massachusetts, before returning to Newport. She the visited Provincetown, Massachusetts, before returning to Newport. Departing on 22 September, she proceeded to Groton, Connecticut, where she remained until September 26. Returning to Newport, that same day, she remained until 5 October, when she got underway for Napeague Bay, New York, and making her return to Newport, on 10 October. While she was en route back into Newport, on 9 October, K-2 detached from the 3rd Division, Submarine Flotilla, Torpedo Flotilla, Atlantic Fleet, and was assigned to the newly-organized 4th Division. Clearing Newport, on 15 October, the submarine arrived later that day at the Submarine Base, New London, Connecticut. She remained there until 3 December, when she returned to Newport, before making her way back to New London, on 8 December. After a cruise, she cleared New London, on 10 December, and arrived at the New York Navy Yard, on 12 December. The boat drydocked at the yard and remained there into January 1915.
