The three Chester-class cruisers were the first United States Navy vessels to be designed and designated as fast "scout cruisers" for fleet reconnaissance. They had high speed but little armor or armament.[2] They were authorized in January 1904, ordered in fiscal year 1905, and completed in 1908. In 1920 all scout cruisers were redesignated as "light cruisers" (CL).[3]

Birmingham was the first ship in the world to launch an airplane, in 1910 with pilot Eugene Ely, who also performed the first landing on a ship the following year, on USS Pennsylvania.[4] The class patrolled the Caribbean prior to World War I, sometimes supporting military interventions, with Chester playing a key role at the start of the United States occupation of Veracruz in 1914. The ships escorted convoys in World War I. The class was decommissioned 1921-1923 and sold for scrap to comply with the limits of the London Naval Treaty in 1930.[3]
Design and construction
editShip type
editThe three Chesters were the US Navy's only ships to be commissioned with the "scout cruiser" (hull classification symbol non-standard at the time, CS or SCR are sometimes used) designation, and were characterized by high speed and little armor or armament. They were also the last cruisers of any type built for the US Navy until the first Omaha-class cruisers were laid down in 1917 (the Navy concentrated on building dreadnought battleships and destroyers in the interim). The first three Omaha-class ships were also designated "scout cruisers" (CS or SCR) when ordered, but before any were launched the Navy revised its classification system and they and the Chesters became "light cruisers" (CL).[2][3]
Armament
editThe as-built armament included two 5 in (127 mm)/50 caliber Mark 6 guns,[5] six 3 in (76 mm)/50 caliber rapid fire (RF) guns,[6] and two 21 inch (533 mm) torpedo tubes.[1] The original design featured a uniform gun armament of twelve 3-inch guns, which was supported by the Navy's General Board as simplifying fire control and echoing the uniform main and secondary armaments of dreadnought battleships. However, two 5-inch guns were substituted for six of the 3-inch guns, apparently to enable the scout cruisers to fight foreign light cruisers.[2] Notably, for the first time in US cruiser design smaller caliber weapons (6-pounder and smaller) were not fitted.
Armor
editThe armor of these ships was very light. A 2 in (51 mm) belt extended 9.5 ft (2.9 m) above the waterline in the engine and generator room area, 6.5 ft (2.0 m) above the waterline in the boiler room area, and 3.25 ft (1 m) below the waterline for its entire length.[2] There was no protective deck, only a 1 in (25 mm) deck above the steering gear.[2]
Engineering
editThe three ships had different propulsion plants so they could be compared: Chester was the first major combatant in the USN to receive steam turbine propulsion of the Parsons type, Salem received Curtis turbines, and Birmingham traditional triple-expansion engines. The design speed was 24 kn (27.6 mph; 44.4 km/h) for the triple-expansion ship and up to 25 kn (28.8 mph; 46.3 km/h) for the turbine ships.[2]
Chester had twelve coal-fired Normand boilers and Parsons direct-drive steam turbines totaling 23,000 shp (17,000 kW) on four shafts.[1] She made 26.52 kn (30.5 mph; 49.1 km/h) on trials at an estimated 16,000 shp (12,000 kW).[2]
Birmingham had twelve coal-fired Fore River boilers supplying 275 psi (1,900 kPa) steam to two four-cylinder vertical triple-expansion engines totaling 16,000 ihp (12,000 kW) (design) on two shafts.[2][7] She made 24.33 kn (28.0 mph; 45.1 km/h) on trials at 15,670 ihp (11,690 kW).[2]
Salem had twelve coal-fired Fore River boilers and Curtis direct-drive steam turbines totaling 23,900 shp (17,800 kW) (design) on two shafts.[2][7] She made 25.95 kn (29.9 mph; 48.1 km/h) on trials at 22,242 shp (16,586 kW).[2]
Normal coal capacity was 475 tons, which could be increased to 1,400 tons.[1]
Refits
editAll three ships were refitted in 1917 to prepare for service in World War I. Salem had her main engines replaced with a 20,000 shp (15,000 kW) General Electric geared steam turbine installation due to high coal consumption. All three received an armament upgrade, with four new 5-inch (127 mm)/51 caliber guns replacing the 5-inch/50 caliber guns as well as two of the 3-inch/50 caliber ,[8] two 3-inch/50 caliber single-purpose guns (four being removed), and two 3-inch/50 caliber anti-aircraft guns added.[9] The submerged torpedo tubes were retained.[1][10]
Ships in class
editThe three ships of the Chester class were:[1][3]
| Ship | Shipyard | Laid down | Launched | Commissioned | Decommissioned | Fate |
|---|---|---|---|---|---|---|
| USS Chester (CS-1) | Bath Iron Works, Bath, Maine | 25 September 1905 | 26 June 1907 | 25 April 1908 | 10 June 1921 | Renamed York 10 July 1928, sold for scrap 13 May 1930 |
| USS Birmingham (CS-2) | Fore River Shipyard, Quincy, Massachusetts | 14 August 1905 | 29 May 1907 | 11 April 1908 | 1 December 1923 | Sold for scrap 13 May 1930 |
| USS Salem (CS-3) | Fore River Shipyard, Quincy, Massachusetts | 28 August 1905 | 27 July 1907 | 1 August 1908 | 16 August 1921 | Sold for scrap 11 February 1930 |
On 17 July 1920 these ships were reclassified with the new hull numbers CL-1 through CL-3 (light cruisers). On 10 July 1928 Chester was renamed York to free the name for USS Chester (CA-27).[3]
