Greetings!
After a longer delay than planned (such is life) - here are the next set of US cruisers - enjoy!
Oakland class (US):
The follow-on to the
Los Angeles class was the six-ship
Oakland class of protected cruisers. They represented a significant advance over the older ships with a new design from the keel up. They not only had more hydrodynamic hulls, but carried their main armament entirely in twin turrets – but retained the triple shaft propulsion scheme of the
Los Angeles’. Laid down between 1899 and 1901, the class consisted of
Oakland, Chicago, Dearborn, Manchester, Cincinnati, and
Warwick. Hull numbers ran from CR-19 to CR-24.
The
Oakland class was 405 feet overall, with a beam of 60 feet and a nominal draft of 21 feet. They displaced 9,570 tons normal and 9,930 tons full load. Main armament consisted of eight 8”/40 Mk. 4 guns in four twin mounts; one forward, one in port and starboard wing positions, and one aft. Secondary guns were twelve 6”/45 Mk.8’s in casemate mounts with a tertiary battery of eight 4”/45” Mk.6 guns in open deck mounts. Torpedo armament consisted of two twin deck-mounted launchers for 18” torpedoes (with sixteen reload torpedoes in stowage bays inboard of the launchers). The
Oakland’s were powered by three four-cylinder triple expansion engines producing 23,850 horsepower and driving these ships easily to their design speed of 22 knots. Range was 5,000 nautical miles. Armor comprised a 2” belt, 2” armored deck, 5” main turrets and barbettes, 4” casemates, and a 4” conning tower. Crew complement was 556.
The new protected cruisers (often referred to semi-officially as 1st Class Cruisers in the British fashion) entered service between 1902 and 1904. They served in both the Western Pacific War and the War of the Americas with USS
Chicago (CR-20) sunk in the former and USS
Dearborn (CA-21) lost during the latter. Re-classed as heavy cruisers (CA prefix – same hull numbers) in the massive USN reorganization of 1920, the surviving ships were deemed obsolete a mere ten years later. USS
Oakland (CA-19), USS
Manchester (CA-22), and USS
Warwick (CA-24) were all scrapped beginning in 1933. USS
Cincinnati (CA-23) was converted to a training ship in 1928 and renamed
Stanford. She served in this role until early 1942 when she was decommissioned.
Bridgeport class (US):
The
Bridgeport class was intended as larger, faster, better armed and protected versions of the
Oakland class and was one of only a handful of US ship designs with more than four funnels – their five funnel arrangement giving them a distinct silhouette. They were also the largest class of cruisers built for the USN until the
Astoria class of 1944. In all ten ships;
Bridgeport, South Bend, Missoula, Kenosha, Omaha, Riverside, Sioux City, Lakewood, Ogden, and
Meridian entered service between 1905 and 1908. Hull numbers ran from CR-25 to CR-34.
The
Bridgeport class was 430 feet overall, with a beam of 60 feet and a nominal draft of 21 feet. They displaced 10,050 tons normal and 10,470 tons full load. Main armament consisted of eight of the new 8”/45 Mk.6 guns in four twin mounts arranged as in the Oakland class. Fourteen 6”/45 Mk.8’s in hull casements comprised the secondary battery while a tertiary battery of eight 4”/45” Mk.6 guns in open deck mounts and two twin 18” deck-mount torpedo launchers with 20 reloads completed the weapons suite.
The last US warships with triple-shaft propulsion as well as the last cruisers powered by triple expansion engines, the
Bridgeport class was powered by three four-cylinder units producing 23,740 horsepower. Top speed remained 22 knots while range increased to 6,000 nautical miles. Armor protection consisted of a 3” belt, 2” armored deck, 5” main turrets and barbettes, 5” casemates, and a 4” conning tower. Crew averaged around 577.
The newest US cruisers in service during the Western Pacific War, the class was heavily involved in the fighting with two, USS
South Bend (CR-26) and USS
Omaha (CR-29) both sunk in 1906 – the same year they were commissioned. Two other members of the class; USS
Kenosha (CR-28) and USS
Sioux City (CR-31) were both lost in 1908 during the Second Battle of Hawaii. After the war, the surviving ships were re-classed as heavy cruisers in 1920 when modernized with oil-fired boilers and redesigned superstructures. Two; USS
Riverside (CR-30), and USS
Ogden (CR-33) were sold to Peru in 1915 and thus retained their original coal-fired boilers. USS
Missoula (CA-27) was sunk by a Confederate submarine in 1925 but the remaining three ships survived the War of the Americas and continued in service until the early 1930’s when they were decommissioned. USS
Meridian (CA-34) was the last to be taken out of service and was scrapped in 1935.
Spokane class (US):
Entering service between 1909 and 1910, the
Spokane class was innovative in a number of ways. They were products of the Tallmadge Era of naval design and thus resembled their contemporaries, the
Helena class of armored cruisers, featuring a hull with raised forecastle deck, tripod masts, and vastly improved uptakes and funnels for their turbine propulsion systems – another first for protected cruisers. In one particular feature, however, they blazed a trail for all US heavy ships to come. Their main armament of ten 8” turrets was two guns heavier than their predecessors, but was more significant for its arrangement – the single turret forward and two amidships turrets (this time mounted en echelon) was commonplace on US ships by this time, but the two aft turrets were arranged as a superfiring pair for the first time in naval history – an innovation soon to spread worldwide as the preferred turret configuration. Ordered during 1905, and laid down between 1906 and 1907, a total of eight ships entered service;
Spokane, Wichita, New Rochelle, Erie, Fall River, Rochester, Elizabeth, and
Hillsboro. Hull numbers ran from CR-35 to CR-42.
The
Spokane class was 497 feet overall, with a beam of 61 feet and a nominal draft of 22 feet. They displaced 10,710 tons normal and 11,590 tons full load. Main armament consisted of ten 8”/45 Mk.6 guns in five twin mounts, while the secondary battery consisted of sixteen 4”/45 Mk.7 guns; ten in unarmored hull casemates and six in open-mounts in the superstructure. Like all US protected cruisers they carried an above deck torpedo battery – two twin launchers for Mk.11 18” torpedoes. Twenty-four reloads were carried.
Four Avondale direct-drive steam turbines drove four shafts producing a top speed of 26 knots from 43,230 shaft horsepower. This speed was often bested in service, however, with speeds of 27 knots or more not uncommon (for example, USS
New Rochelle reached 27.6 knots in light-ship conditions in 1913). Range was an impressive 7,000 nautical miles. Armor was similar to the earlier
Bridgeport class with the most significant improvements being a 2.5” armored deck and conning tower armor increased to 5”. Crew compliment rose to 605.
Entering service too late to serve in the Western Pacific War, the new cruisers were nevertheless a valuable addition to the peacetime fleet. Like their predecessors, the
Spokane class was re-classed as heavy cruisers in 1920 and was converted to oil-burners beginning in late 1919. In an unusual move, two of the class; USS
Fall River (CA-39) and USS
Elizabeth (CA-41) were sold to Argentina to counter a build-up in heavy warships by Brazil. Three of the class; USS
Wichita (CA-36), USS
New Rochelle (CA-37), and USS
Hillsboro (CA-42) were sunk during the War of the Americas –
Wichita being lost during a gun-duel with the superdreadnought CSS
Lafayette in the Caribbean in 1925 following the Confederate ship’s breakout from Mobile. USS
Rochester (CA-40) survived the war and was donated to the city of Boston as a museum ship in 1930. The last active members of this class; USS
Spokane (CA-35), and USS
Erie (CA-38), remained in active service until 1935.
Next up: US Scout (Light) cruisers.
