British U-class Submarine
The British U-class submarines (officially "''War Emergency 1940 and 1941 programmes, short hull''") were a class of 49 small submarines built just before and during the Second World War. The class is sometimes known as the ''Undine'' class, after the first submarine built. A further development was the British V-class submarine of 1942. Background The Royal Navy was limited to no more than of submarines by the London Naval Treaty of 1930. The tonnage limit led to proposals for smaller submarines which was also prompted by trials with larger submarines demonstrating that they were easier to find and lacked manoeuvrability. By coincidence the First World War-vintage H-class submarines used for training in anti-submarine warfare were reaching the end of their useful service. The Rear-Admiral Submarines, Noel Laurence, wanted a class of small, inexpensive boats for training, armed with torpedoes for short-range patrols. In March 1934 wrote a specification for a "Small, Simpl ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

U-class Destroyer
The U and V class was a class of sixteen destroyers of the Royal Navy launched in 1942–1943. They were constructed in two flotillas, each with names beginning with "U-" or "V-" (although there was a return to the pre-war practice of naming the designated flotilla leader after a famous naval figure from history to honour the lost ships ''Grenville'' and ''Hardy''). The hull was nearly identical to the preceding ships of the S and T classes, but the U and V class ships had different bridge and armament fits. The flotillas constituted the 7th Emergency Flotilla and 8th Emergency Flotilla, built under the War Emergency Programme. These ships used the Fuze Keeping Clock HA Fire Control Computer. Notable actions Four ships, ''Verulam'', ''Venus'', ''Vigilant'' and ''Virago'', formed part of the 26th Destroyer Flotilla that ambushed and sank the , off Sumatra.

SR U Class
The SR U class are 2-6-0 steam locomotives designed by Richard Maunsell for passenger duties on the Southern Railway (SR). The class represented the penultimate stage in the development of the Southern Railway's 2-6-0 "family", which improved upon the basic principles established by GWR Chief Mechanical Engineer (CME) George Jackson Churchward for Great Western Railway (GWR) locomotives. The U class design drew from experience with the GWR 4300s and N classes, improved by applying Midland Railway ideas to the design, enabling the SECR to influence development of the 2-6-0 in Britain.Scott-Morgan, p. 46 The U class was designed in the mid-1920s for production at a time when more obsolete 4-4-0 locomotives were withdrawn, and derived from Maunsell's earlier SECR K (“River”) class 2-6-4 tank locomotives. The first 20 members of the U class were rebuilds of the K class locomotives, one of which was involved in the Sevenoaks railway accident. A further 20 U ...

GNRI Class U
The GNR(I) class U was a class of 4-4-0 steam locomotives built for the Great Northern Railway (Ireland). History Five were built by Beyer, Peacock and Company in 1915. The class was so successful that an additional batch of five was built in 1947, making them the last inside-cylinder 4-4-0 locomotives to be manufactured anywhere in the world.Kelly (1993) p.21 The earlier locomotives were initially unnamed. However, after the later locomotives were delivered with names of counties along the GNR(I) route, the earlier locomotives received names of Loughs. Withdrawal All were still in service in 1958 when the GNR(I) was divided between the Ulster Transport Authority (UTA) and Córas Iompair Éireann (CIÉ), with each receiving five locomotives. No. 198 ''Lough Swilly'' was the first to be withdrawn in 1959 before its CIÉ number (198N) was applied. CIÉ withdrew steam traction in 1963, whereas the UTA withdrew their U class fleet between 1961 and 1965. None of the class were pre ...

NER Class U
The NER Class U (LNER Class N10) was a class of 0-6-2 tank locomotives of the North Eastern Railway. It was designed by Wilson Worsdell and introduced in 1902. Use The locomotives were used for shunting and on goods trains. All were fitted with Westinghouse brakes. Numbering The whole class was transferred from the NER to the London and North Eastern Railway The London and North Eastern Railway (LNER) was the second largest (after LMS) of the "Big Four" railway companies created by the Railways Act 1921 in Britain. It operated from 1 January 1923 until nationalisation on 1 January 1948. At tha ... (LNER) in 1923 and to British Railways (BR) in 1948. Numbers (where known) are shown below.

NZR U Class
The NZR U class, the first tender locomotives built in New Zealand, were a class of 4-6-0 Ten Wheeler locomotive designed to the requirements of Mr T. F. Rotherham and built at NZR Addington between 1894 and 1903. They were amongst NZRs' longest lived tender engines. Origin and Design The U class was designed to fill a need to provide more powerful and faster passenger locomotives than the N and V classes then in service. The class were the first express locomotives on the NZR to have Walschaerts valve motion and also introduced the 4' 6" driving wheel which would be considered standard for express passenger work. They did however have flat slide valves and would be the last NZR locomotives so built. The U's were the first tender locomotives built in New Zealand and were a significant step in the country's industrial capability. However, Addington was not yet set up for mass production and construction was intermittent and drawn out, resulting in changes to the design over the ...

Russian Locomotive Class U
The Russian locomotive class U (Russian: У) was a Russian express passenger steam locomotive type. The class U was a 4-6-0 four-cylinder compound locomotive which used de Glehn compound system. One unit, Locomotive U-127 was preserved as part of a memorial to Vladimir Lenin, at the Museum of the Moscow Railway Design development Steam locomotives with the wheel arrangement 4-6-0 were widely used on the Russian railways in the late 19th and early 20th century. A rigid base formed by three driving axles ensured a smooth ride on straight tracks without much sideways movement, and а two-axial steering bogie meant good performance on curve tracks. 4-6-0 locomotives of most popular Russian class А were being used among others on the Ryazan-Urals Railway and covered Russia's passenger transportation needs until 1901, when the necessity to build a more powerful locomotive class emerged. A weak track structure with a light load carrying capacity limited the axle load. Operationa ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

South African Class U 2-6-2+2-6-2
The South African Railways Class U 2-6-2+2-6-2 of 1927 was an articulated steam locomotive. In 1927, the South African Railways placed ten Class U Union Garratt articulated steam locomotives with a 2-6-2+2-6-2 Double Prairie type wheel arrangement in service. The locomotive design embodied the Garratt design at the front end and the Modified Fairlie design at the rear end.Espitalier, T.J.; Day, W.A.J. (1945). ''The Locomotive in South Africa - A Brief History of Railway Development. Chapter VII - South African Railways (Continued).'' South African Railways and Harbours Magazine, December 1945. pp. 968-969. Manufacturer Specifications for the Class GJ 2-6-2+2-6-2 Garratt locomotive were prepared by Colonel F.R. Collins DSO, Chief Mechanical Engineer of the South African Railways (SAR) in 1925, but the class designation was changed to Class U when orders for its design and construction were placed with Maffei in Munich, Germany. The locomotive design deviated from the Garratt p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

UCLASS
The Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) was a United States Navy program to develop an autonomous carrier-based unmanned combat aerial vehicle providing an unmanned intelligence and strike asset to the fleet. After debate over whether the UCLASS should primarily focus on stealthy bombing or scouting, the Pentagon instead changed the program entirely into the Carrier-Based Aerial-Refueling System (CBARS) to create a UAV for aerial refueling duties to extend the range of manned fighters,Good-Bye, UCLASS; Hello, Unmanned Tanker, More F-35Cs In 2017 Budget - Breakingdefense.com, 1 February 2016 which lead to the [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
