USS Defiant (YT-804) Returning To Bremerton 2012 June 25
The USS ''Defiant'' is the name of two starships in the Star Trek media franchise, most notably featured in the television series ''Star Trek: Deep Space Nine'' (1993–1999) and the film '' Star Trek: First Contact'' (1996). Introduced in ''Deep Space Nine'''s third season, it is a warship attached to the show's eponymous space station. The original ''Defiant'' is destroyed during the Dominion War in the seventh season and replaced with an identical ship. The ''Defiant'' was designed by Jim Martin, Gary Hutzel and Tony Meinger. Design and development For the first two seasons of ''Deep Space Nine'', stories requiring characters to travel off-station typically involved small runabout vessels. Producer Ira Steven Behr and writer Robert Hewitt Wolfe believed runabouts would be insufficient to confront the adversarial Dominion introduced in the second season, and they convinced executive producer Rick Berman of the need for a new ship. Additionally, the ''Defiant'' was intende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schottel (company)
Schottel is a manufacturer of propulsion and steering systems for ships and offshore applications. The company founder Josef Becker invented the rudderpropeller, a z-drive, in 1950. Today the company develops and manufactures azimuth propulsion, maneuvering and steering systems. In 2014 the subsidiary Schottel Hydro was founded to bundle up the company activities in the hydrokinetic energy segment. History Early beginnings In 1921 Josef Becker (1897–1973) founded his craftsman's enterprise in an old farmhouse in Spay on the Rhine. In 1925 he designed and built his first shallop, followed by the first motorboat in 1928. In the mid 1930s Becker bought part of the present-day company premises and founded Schottel Werft. He named his enterprise after a section of the river Rhine which is called ''Auf der Schottel'' and located close by in Osterspai. From shipyard to ship propulsion With the beginning of the 1950s Becker started working on his invention, a ship propeller that is ...

Z-drive
A Z-drive is a type of marine propulsion unit. Specifically, it is an azimuth thruster. The pod can rotate 360 degrees allowing for rapid changes in thrust direction and thus vessel direction. This eliminates the need for a conventional rudder. The Z-drive is so named because of the appearance (in cross section) of the mechanical driveshaft or transmission configuration used to connect the mechanically supplied driving energy to the ''Z-Drive'' azimuth thruster device. This form of power transmission is called a Z-drive because the rotary motion has to make two right angle turns, thus resembling the letter "Z". This name is used to differentiate the arrangement of drive to that of the L-drive. It does not refer to an electric motor in a rotating pod. The device is different from the Voith-Schneider marine propulsion system (also mechanically linked), which can also quickly change the direction of thrust, as the ''Z-drive'' uses a shrouded conventional screw A screw and a ...

Ships Built In Tacoma, Washington
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...
