USNS Bull Run (T-AO-156)
The SS ''Bull Run'' was a type T2 tanker built at Sun Shipbuilding and Drydock Co. Sun Shipbuilding & Drydock Company (1917–1989) was a major shipbuilding company in Chester, Pennsylvania on the Delaware River. Its primary product was tankers, but the company built many types of ships over its 70-year history. During World W ... in Chester, PA as hull number 287 and USMC number 362 in 1943. In 1956, the ship was acquired by the US Navy from the Maritime Administration, assigned to MSTS, and placed in-service as the USNS ''Bull Run'' (T-AO-156). She left the navy in 1957, going back to the Maritime Administration. In 1969, the stern of the ''Bull Run'' was attached to the bow of the Type C4 ship the ''Anchorage'', and the completed ship then retained the name ''Anchorage''. The bow of the ''Bull Run'' was then scrapped. References T2Tanker.org Type T2-SE-A1 tankers 1943 ships Ships built by the Sun Shipbuilding & Drydock Company World War II tankers of the Un ...

Second Battle Of Bull Run
The Second Battle of Bull Run or Battle of Second Manassas was fought August 28–30, 1862, in Prince William County, Virginia, as part of the American Civil War. It was the culmination of the Northern Virginia Campaign waged by Confederate Gen. Robert E. Lee's Army of Northern Virginia against Union Maj. Gen. John Pope's Army of Virginia, and a battle of much larger scale and numbers than the First Battle of Bull Run (or First Manassas) fought on July 21, 1861 on the same ground. Following a wide-ranging flanking march, Confederate Maj. Gen. Thomas J. "Stonewall" Jackson captured the Union supply depot at Manassas Junction, threatening Pope's line of communications with Washington, D.C. Withdrawing a few miles to the northwest, Jackson took up strong concealed defensive positions on Stony Ridge and awaited the arrival of the wing of Lee's army commanded by Maj. Gen. James Longstreet. On August 28, 1862, Jackson attacked a Union column just east of Gainesville, at Brawn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth. The Sun's radius is about , or 109 times that of Earth. Its mass is about 330,000 times that of Earth, comprising about 99.86% of the total mass of the Solar System. Roughly three-quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron. The Sun is a G-type main-sequence star (G2V). As such, it is informally, and not completely accurately, referred to as a yellow dwarf (its light is actually white). It formed approximately 4.6 billionAll numbers in this article are short scale. One billion is 109, or 1,000,000,000. years ago f ...

T2 Tanker
The T2 tanker, or T2, was a class of oil tanker constructed and produced in large quantities in the United States during World War II. Only the T3 tankers were larger "navy oilers" of the period. Some 533 T2s were built between 1940 and the end of 1945. They were used to transport fuel oil, diesel fuel, gasoline and sometimes black oil-crude oil. Post war many T2s remained in use; like other hastily built World War II ships pressed into peacetime service, there were safety concerns. As was found during the war, the United States Coast Guard Marine Board of Investigation in 1952 stated that in cold weather the ships were prone to metal fatigue cracking, so were "belted" with steel straps. This occurred after two T2s, and , split in two off Cape Cod within hours of each other. ''Pendleton''s sinking is memorialized in '' The Finest Hours''. Engineering inquiries into the problem suggested the cause was poor welding techniques. It was found the steel (that had been successfully use ...

Tanker (ship)
A tanker (or tank ship or tankship) is a ship designed to transport or store liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, and gas carrier. Tankers also carry commodities such as vegetable oils, molasses and wine. In the United States Navy and Military Sealift Command, a tanker used to refuel other ships is called an oiler (or replenishment oiler if it can also supply dry stores) but many other navies use the terms tanker and replenishment tanker. Tankers were first developed in the late 19th century as iron and steel hulls and pumping systems were developed. As of 2005, there were just over 4,000 tankers and supertankers or greater operating worldwide. Description Tankers can range in size of capacity from several hundred tons, which includes vessels for servicing small harbours and coastal settlements, to several hundred thousand tons, for long-range haulage. Besides ocean- or seagoing tankers there are also specialized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbo-electric
A turbo-electric transmission uses electric generators to convert the mechanical energy of a turbine (steam or gas) into electric energy, which then powers electric motors and converts back into mechanical energy that power the driveshafts. Turbo-electric drives are used in some rail locomotives (gas turbines, ''e.g.'' with the first TGV) and ships (steam and more recently gas turbines). An advantage of turbo-electric transmission is that it allows the adaptation of high-speed turbines to slow turning propellers or wheels without a heavy and complex gearbox. It has the advantage of being able to provide electricity for the ship or train's other electrical systems, such as lighting, computers, radar, and communications equipment. Other advantages for ships include greater watertight subdivision, quieter operations, and safety (via instant thrust reversal by changing engine direct current polarity) for submarines.Friedman, 1994, pp 136, 147–149 Ships with turbo-electric drive ...
