USS R-24 (SS-101), also known as "Submarine No. 101", was an R-21-class coastal and harbor defense submarines of the United States Navy commissioned after the end of World War I.

Design

The R-boats built by the Lake Torpedo Boat Company, R-21 through R-27, are sometimes considered a separate class, R-21-class, from those built by the Fore River Shipbuilding Company, R-1 through R-14, and the Union Iron Works, R-15 through R-20, R-1-class.[2]

The submarines had a length of 175 feet (53.3 m) overall, a beam of 16 ft 7 in (5.1 m), and a mean draft of 13 ft 11 in (4.2 m). They displaced 497 long tons (505 t) on the surface and 652 long tons (662 t) submerged. The R-21-class submarines had a crew of 3 officers and 23 enlisted men. They had a diving depth of 200 ft (61.0 m).[2][4]

For surface running, the boats were powered by two 500-brake-horsepower (373 kW) Busch-Sulzer diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 400-horsepower (298 kW) Diehl Manufacture Company electric motor. They could reach 14 knots (26 km/h; 16 mph) on the surface and 11 kn (20 km/h; 13 mph) underwater. On the surface, the R-21-class had a range of 3,523 nautical miles (6,525 km; 4,054 mi) at 11 kn (20 km/h; 13 mph), or 6,499 nmi (12,036 km; 7,479 mi) if fuel was loaded into their main ballast tanks.[4]

The boats were armed with four 21-inch (533 mm) torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes. The R-21-class submarines were also armed with a single 3 in (76 mm)/50 caliber deck gun.[2][4]

Construction

R-24's keel was laid down on 9 May 1919, by the Lake Torpedo Boat Company, of Bridgeport, Connecticut. She was launched on 21 August 1918,[5] sponsored by Mrs. Elizabeth Norton,[6] and commissioned on 27 June 1919, with future Rear Admiral, Lieutenant Commander Andrew Carl Bennett in command.[5]

Service history

After four months of coastal operations off southern New England, R-24 got underway for her homeport, Coco Solo, in the Panama Canal Zone, on 1 November.[5]

When the US Navy adopted its hull classification system on 17 July 1920, she received the hull number SS-101.[3]

At the end of 1921, she returned to the United States for a shipyard overhaul. In the fall of 1922, she resumed operations out of Coco Solo, and Balboa. A year later she again sailed to the United States, for a shipyard overhaul, and at the end of 1924, she returned for inactivation.[5]

Fate

On 25 January 1925, she arrived at the Philadelphia Navy Yard, and on 11 June, she was decommissioned after only five-and-a-half years of service. R-24 was berthed at League Island, for the next five years. On 9 May 1930, she was struck from the Naval Vessel Register, and on 30 July 1930, she was sold for scrapping.[5]
