The Type V ship is a United States Maritime Commission (MARCOM) designation for World War II tugboats . Type V was used in World War II, Korean War , and the Vietnam War . Type V ships were used to move ships and barges . Type V tugboats were made of either steel or wood hulls . There were four types of tugboats ordered for World War II. The largest type V design was the sea worthy 186-foot (57 m) long steel hull, V4-M-A1. The V4-M-A1 design was used by a number of manufacturers; a total of 49 were built. A smaller steel hull tugboat was the 94-foot (29 m) V2-ME-A1; 26 were built. The largest wooden hull was the 148-foot (45 m) V3-S-AH2, of which 14 were built. The smaller wooden hull was the 58-foot (18 m) V2-M-AL1, which 35 were built. Most V2-M-AL1 tugboats were sent to the United Kingdom for the war efforts under the lend-lease act. The Type V tugs served across the globe during World War II including: Pacific War , European theatre , and in the United States. SS Farallon , and other Type V tugs, were used to help built Normandy ports , including Mulberry harbour , on D-Day, 6 June 1944, and made nine round trips to Normandy to deliver Phoenix breakwaters .

252-503: A direct mechanical connection between the combustion engine and propeller, switching between diesel engines for surface running and electric motors for submerged propulsion. This was effectively a "parallel" type of hybrid, since the motor and engine were coupled to the same shaft. On the surface, the motor (driven by the engine) was used as a generator to recharge the batteries and supply other electric loads. The engine would be disconnected for submerged operation, with batteries powering
294-660: A direct-drive diesel locomotive would require an impractical number of gears to keep the engine within its powerband; coupling the diesel to a generator eliminates this problem. An alternative is to use a torque converter or fluid coupling in a direct drive system to replace the gearbox. Diesel electric based buses have also been produced, including hybrid systems able to run on and store electrical power in batteries. The two main providers of hybrid systems for diesel–electric transit buses include Allison Transmission and BAE Systems .

1470-442: The mid-1910s, the technology was immediately reintroduced when Sweden began to design its own submarines again in the mid-1930s. From that point onwards, diesel–electric transmission has been consistently used for all new classes of Swedish submarines, albeit supplemented by air-independent propulsion (AIP) as provided by Stirling engines beginning with HMS Näcken in 1988. Another early adopter of diesel–electric transmission
1512-545: The other hand, were designed for diesel–electric propulsion because of its flexibility and resistance to damage. Some modern diesel–electric ships, including cruise ships and icebreakers, use electric motors in pods called azimuth thrusters underneath to allow for 360° rotation, making the ships far more maneuverable. An example of this is Symphony of the Seas , the largest passenger ship as of 2019. Gas turbines are also used for electrical power generation and some ships use
1554-733: The pioneering users of true diesel–electric transmission was the Swedish Navy with its first submarine, HMS Hajen (later renamed Ub no 1 ), launched in 1904 and originally equipped with a semi-diesel engine (a hot-bulb engine primarily meant to be fueled by kerosene), later replaced by a true diesel. From 1909 to 1916, the Swedish Navy launched another seven submarines in three different classes ( 2nd class , Laxen class , and Braxen class ), all using diesel–electric transmission. While Sweden temporarily abandoned diesel–electric transmission as it started to buy submarine designs from abroad in
