The most expensive and largest destroyer built by the United States

Submarine Structure & Systems: "The Submarine: Construction" pt2-2 1955 US Navy
USS Tusk (SS-426), a Balao-class submarine, was the only ship of the United States Navy to be named for the tusk, an alternate name for the cusk, a large edible saltwater fish related to the cod. Her keel was laid down on 23 August 1943 at Philadelphia, Pennsylvania, by the Cramp Shipbuilding Company. She was launched on 8 July 1945 sponsored by Mrs. Carolyn Park Mills, and commissioned on 11 April 1946 with Commander Raymond A.
The Balao class was a successful design of United States Navy submarine used during World War II, and with 122 units built, the largest class of submarines in the United States Navy. An improvement on the earlier Gato class, the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m). Tang actually achieved a depth of 612 ft (187 m) during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer.
Propulsion
The propulsion of the Balao-class submarines was generally similar to that of the preceding Gato-class. Like their predecessors, they were true diesel-electric submarines: their four diesel engines powered electrical generators, and electric motors drove the shafts. There was no direct connection between the main engines and the shafts.
Balao-class submarines received main engines from one of two manufacturers. Fairbanks-Morse supplied Model 38D8-⅛ opposed piston engines, and General Motors' Electro-Motive Diesel division supplied Model 16 V16 engines. Earlier Fairbanks-Morse boats received a 9-cylinder version of the Model 38D8-⅛, while boats from USS Sand Lance (SS-381) onward received 10-cylinder engines. Earlier GM boats received Model 16-248 engines, but beginning with USS Perch (SS-313) Model 16-278A engines were used. In each case, the newer engines had greater displacement than the old, but were rated at the same power; they operated at lower mean effective pressure for greater reliability...
Two manufacturers supplied electric motors for the Balao-class. Elliott Company motors were fitted primarily to boats with Fairbanks-Morse engines. General Electric motors were fitted primarily to boats with General Motors engines, but some Fairbanks-Morse boats received GE motors. Allis-Chalmers motors were to be used in SS-530 through SS-536, but those seven boats were cancelled before even receiving names.
Earlier submarines carried four high-speed electric motors (two per shaft), which had to be fitted with reduction gears to slow their outputs down to an appropriate speed for the shafts. This reduction gearing was very noisy, and made the submarine easier to detect with hydrophones. A handful of late Balao-class submarines received low-speed double armature motors which drove the shafts directly and were much quieter, but this improvement was not universally fitted until the succeeding Tench-class. As the diesel engines were not directly connected to the shafts, the electric motors had to drive the shafts all the time.
The Balao class was successful, and one of its class USS Archer-Fish (SS-311) brought down what remains the largest ship sunk by a submarine, the Japanese aircraft carrier Shinano (59,000 tons).
As of 2007 USS Tusk (SS-426), a Balao-class submarine, was one of the last two operational submarines in the world built during World War II. It was transferred to the Republic of China in the early 1970s...

Google si ASUS planuiesc sa lanseze o tableta quad-core din seria Nexus care va costa 199$
Desi tableta trebuia sa intre in productie in luna mai, Google a amanat planurile pentru a mai reduce 50$ din pretul final al dispozitivului si ramane de vazut daca decizia lor va fi una buna sau nu. Tableta lor va intra pe o piata in care nu exista prea multa concurenta deoarece Kindle Fire se vinde extrem de bine si restul tabletelor cu ecran de 7 inch nu prea au succes. Cu o tableta de acest gen Google ar putea afecta vanzarile tabletei iPad si ar putea fura o parte din cota de piata a produsului din Cupertino insa ramane de vazut cum se va prezenta “Google Nexus Tab”.
The Mountain View team plans to make some design changes and hopes to lower the price from the current $249. The tablet, made in partnership with Taiwan’s Asustek Computer, currently comes with a 7-inch screen, an Nvidia Tegra 3 quad-core processor, and is Wi-Fi-only. It runs Android 4.0, Ice Cream Sandwich. The $249 price tag on the current Google-Asustek tablet is higher than previous reports of a $149-$199 device. Amazon’s Kindle Fire, another 7-inch tablet that retails for $199, is the obvious competitor that Google will be taking on in that size and price range.
