context_page_description: USS Orizaba was a transport ship for the United States Navy in both World War I and World War II. She was the sister ship of Siboney but the two were not part of a ship class. In her varied career, she was also known as USAT Orizaba in service for the United States Army, and as SS Orizaba in interwar civilian service for the Ward Line, and as Duque de Caxias as an auxiliary in the Brazilian Navy after World War II.
  Orizaba made 15 transatlantic voyages for the navy carrying troops to and from Europe in World War I with the second-shortest average in-port turnaround time of all navy transports. The ship was turned over to the War Department in 1919 for use as army transport USAT Orizaba. After her service in World War I ended, Orizaba reverted to the Ward Line, her previous owners. The ship was briefly engaged in transatlantic service to Spain and then engaged in New York–Cuba–Mexico service until 1939, when the ship was chartered to United States Lines. While Orizaba was in her Ward Line service, American poet Hart Crane leapt to his death from the rear deck of the liner off Florida in April 1932.
context_section_description: Orizaba—named after the town of Orizaba, Veracruz, Mexico—was laid down for the Ward Line by William Cramp & Sons Ship and Engine Building Company of Philadelphia and launched in February 1917. In mid-1917 the United States Shipping Board (USSB) commandeered and received title to all private shipbuilding projects in progress, including the still-incomplete Orizaba and her sister ship Siboney. Plans for both ships were modified for troop-carrying duties. Upon Orizaba's completion, the USSB delivered her to the US Navy for transport duty on 11 April 1918, and she was commissioned as USS Orizaba (ID-1536) on 27 May.
  Assigned to the Atlantic Transport Service, Orizaba carried over 15,000 troops in six convoy trips to France before the end of World War I. In one such voyage, Orizabas executive officer, ordnance expert William Price Williamson, worked closely with Commander Richard Drace White—Orizabas commanding officer, himself an ordnance expert—to develop a workable depth charge launcher which would provide the transport with a measure of protection from enemy submarines. Williamson set about modifying a Lyle gun into a depth charge launcher, and successfully tested it on 16 August 1918. While attempting another test with an increased propellant charge the following day, a defective fuse exploded the depth charge prematurely, killing Williamson and three other sailors. White, four other officers, and twenty-two enlisted men were also wounded in the blast.
  Four days later on 21 August at 08:30, Orizaba, traveling with Siboney, spotted a submarine in the act of submerging. Orizaba attempted to ram the sub and dropped depth charges, but there was no indication that the attack was successful.
  In December 1918, she was temporarily assigned to assist the French government in repatriating French, Belgian, and Italian prisoners of war. Detached from that duty on 10 January 1919, she joined the Cruiser and Transport Force at Brest, and in nine voyages returned over 31,700 troops to the United States. After the completion of transport duty service in the summer of 1919, she was decommissioned on 4 September and subsequently turned over to the Army for further transport service as USAT Orizaba. The boat served in that capacity until returned to the Ward Line in 1920.
  According to the Statistical Department of the US Navy, Orizaba had the second-shortest average in-port turnaround time out of 37 US Navy transports used in World War I. The ship completed 15 round trips with an average turn-around time of just over 30 days per trip, while the overall Navy average was 39.8 days.
