Description

The L-class boats designed by Lake Torpedo Boat (L-5 through L-8) were built to slightly different specifications from the other L boats, which were designed by Electric Boat, and are sometimes considered a separate L-5 class. The Lake boats had a length of 165 feet (50.3 m) overall, a beam of 14 feet 9 inches (4.5 m) and a mean draft of 13 feet 3 inches (4.0 m). They displaced 451 long tons (458 t) on the surface and 527 long tons (535 t) submerged. The L-class submarines had a crew of 28 officers and enlisted men. They had a diving depth of 200 feet (61.0 m). [1]

For surface running, the boats were powered by two 600- brake-horsepower (447 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 400-horsepower (298 kW) electric motor. They could reach 14 knots (26 km/h; 16 mph) on the surface and 10.5 knots (19.4 km/h; 12.1 mph) underwater. On the surface, the Lake boats had a range of 5,150 nautical miles (9,540 km; 5,930 mi) at 11 knots (20 km/h; 13 mph) [1] and 150 nmi (280 km; 170 mi) at 5 knots (9.3 km/h; 5.8 mph) submerged. [2]

The boats were armed with four 18-inch (450 mm) torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes. The L-class submarines were also armed with a single 3"/50 caliber deck gun. [2]

Construction and career

L-6's keel was laid down on 27 May 1914 by Craig Shipbuilding Company in Long Beach, California. L-6 was launched on 31 August 1916 sponsored by Mrs. William R. Monroe, and commissioned on 7 December 1917.

After exercises along the West Coast, L-6 departed Pacific waters on 20 April 1918, arriving Charleston, South Carolina, on 10 June. Following a brief overhaul, the submarine patrolled off Charleston until she sailed on 15 October for the eastern Atlantic. Arriving Ponta Delgada, Azores, in early November, L-6 joined Submarine Division 6 just prior to the signing of the Armistice with Germany on 11 November.

After making stops in Caribbean Sea and Central American ports, L-6 arrived San Pedro, California, on 14 February 1919, completing one of the best long-distance seagoing performances of the United States's youthful submarine force. From 1919 to 1922, she remained on the West Coast, experimenting with new torpedoes and undersea detection equipment. L-6 was placed in commission, in ordinary, on 24 March 1922; returned to full commission on 1 July; and sailed for the East Coast the same month. Upon arrival Hampton Roads, L-6 decommissioned on 25 November 1922, and was sold to M. Samuel and Sons on 21 December 1925 for scrapping.
