The second USS ''Sacramento'' (PG-19) was a gunboat in the United States Navy. ''Sacramento'' was launched on 21 February 1914 by the William Cramp & Sons Shipbuilding Company, Philadelphia; sponsored by Miss Phebe Briggs; and commissioned on 26 April 1914 at the Philadelphia Navy Yard under the command of Commander Luke McNamee. ==Construction and design== In 1911, it was decided to order a new gunboat as a cheaper alternative to the US Navy's ''Denver''-class cruisers, designed to patrol in the Caribbean. The new ship would carry much less armament and not be able to carry troops, allowing a much smaller ship. Construction of the ship was authorized by Act of Congress on 4 March 1911, but no shipyard was willing to build the Navy's design for the target cost of $500,000, and the Navy was forced to further reduce the design, cutting speed and range, before it could be ordered.〔 The final design was long overall and long between perpendiculars, with a beam of and a draft of . The ship was of flush decked design and was made of steel. Displacement was normal and full load.〔 A single three-cylinder triple expansion engine, rated at , drove a single shaft, and were supplied with two Babcock and Wilcox coal-fired water-tube boilers feeding steam at . This gave a contract speed of . 428 t of coal were carried, giving a range of .〔 The ship was armed with three 4-inch 50 calibre guns, with two 3-pounder saluting guns and two 1-pounder guns. The ship had a complement of 163 officers and men.〔 ''Sacramento'' (or Gunboat No. 19) was ordered from William Cramp & Sons at a contract price of $492,500,〔 and was laid down at Cramp's Philadelphia shipyard on 30 April 1913. She was launched on 21 February 1914, and successfully met her contracted speed during sea trials on 31 March–1 April, reaching a maximum speed of and an average speed of on a 4-hour speed run. She was commissioned on 26 April 1914.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「USS Sacramento (PG-19)」の詳細全文を読む スポンサード リンク
