TR-1700-class Submarine
The TR-1700 (''Santa Cruz'') is a class of diesel-electric patrol submarines built by Thyssen Nordseewerke for the Argentine Navy in the 1980s, with two submarines completed. These ships are amongst the largest submarines built in Germany since World War II and are among the fastest diesel-electric submarines in the world. ARA ''San Juan'' was lost on 17 November 2017, leaving ARA ''Santa Cruz'' as the only remaining submarine of this class. As of 2020, the refit of ''Santa Cruz'' has been reported cancelled leaving the entire class inactive. Development The original 1977 plan called for six boats, two TR-1700s built in Germany by Thyssen Nordseewerke, two in Argentina by Astillero Domecq Garcia, and two smaller TR-1400s also built in Argentina. The final agreement in 1982 was modified to six TR-1700s, with the last four to be built in Argentina. The TR-1700s to be built in Argentina were considered for an upgrade to a nuclear submarine.

Mark 37 Torpedo
The Mark 37 torpedo is a torpedo with electrical propulsion, developed for the US Navy after World War II. It entered service with the US Navy in the early 1950s, with over 3,300 produced. It was phased out of service key with the US Navy during the 1970s, and the stockpiles were sold to foreign navies. Development Its engineering development began in 1946 by Westinghouse. It was largely based on the concept of the passive homing Mark 27, with added active homing system tested on modified Mark 18s, and a new torpedo body. Between 1955–56, thirty torpedoes were produced for development testing, with large-scale production commenced shortly afterwards. Due to its electric propulsion, the torpedo swam smoothly out of the launch tube, instead of having to be ejected by pressurized air, therefore significantly reducing its acoustic launch signature. To allow for water flow around the torpedo while swimming out, several 1" thick guide studs were attached to the torpedo, which alth ...

Disappearance Of ARA San Juan
On 15 November 2017, the Argentine submarine disappeared off the coast of Argentina while on a training exercise. After a search lasting 15 days, the Argentine Navy downgraded the operation from a rescue mission to a search for the submarine's wreck, implying they had given up any hope of finding survivors among its crew of 44. It was the worst submarine disaster since the accident on in 2003, and the second worst peacetime naval disaster in Argentina after the 1949 sinking of the minesweeper .

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and .

Cannibalization (parts)
Cannibalization of machine parts, in the maintenance of mechanical or electronic systems with interchangeable parts, refers to the practice of removing parts or subsystems necessary for repair from another similar device, rather than from inventory, usually when resources become limited. The source system is usually crippled as a result, perhaps only temporarily, in order to allow the recipient device to function properly again. Cannibalization usually occurs due to unavailability of spare parts, an emergency, long resupply times, physical distance, or insufficient planning/budget. Cannibalization can also be due to reusing surplus inventory. At the end of World War II a large quantity of high quality, but unusable war surplus equipment such as radar devices made a ready source of parts to build radio equipment. Cannibalization can also be an economic/ecological choice for end of life products. Germany, rather than sell/export functional used cars, will disassemble and store ...
