M74 Light Mortar
The M74 mortar is designed by Military Technical Institute in Yugoslavia. It is smooth bore, muzzle-loading, high-angle-of-fire weapon used for long-range indirect fire support. Today they are produced by Serbian company PPT Namenska and BNT from Bosnia and Herzegovina. Description This mortar can be deployed as infantry support for destruction of personnel and enemy firing positions, for opening routes through barbed wire obstacles and mine fields, for demolition of fortified objects, for destructing infrastructure elements, illumination and deploying smoke screen. The M74 model when disassembled could be carried by 3 soldiers thus having unique capabilities regarding transport in area with obstacles or in urban area compared with more heavier mortars. M74 provides 12 rds per minute rate of fire and it is intended to be used to deliver 15-20 mines before moving to another position. Since it is very light regarding its caliber it can be easily airdropped and parachuted to firin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M74 Motorway
The A74(M) and M74 form a major motorway in Scotland, connecting it to England. The routes connect the M8 motorway in central Glasgow to the Scottish-English border at Gretna. In conjunction with their southward continuation, the M6 motorway, they form one of the three major cross-border routes between Scotland and England. They are part of the unsigned international E-road network E05. Although the entire route is colloquially referred to as the M74, for more than half its length, south of Abington, the road is officially the A74(M); see ''naming confusion'' below. Route From its junction with the M8 just south of the Kingston Bridge, the newest section passes through the Glasgow districts of Govanhill, Polmadie, Oatlands and parts of the nearby towns of Rutherglen and Cambuslang, on an elevated embankment, with junctions at Kingston, Polmadie Road, Eastfield and Tollcross before connecting to the much older section of the M74. It then runs in a roughly south-easter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messier 74
Messier 74 (also known as NGC 628 and Phantom Galaxy) is a large spiral galaxy in the equatorial constellation Pisces. It is about 32 million light-years away from Earth. The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy. The galaxy's low surface brightness makes it the most difficult Messier object for amateur astronomers to observe. Its relatively large angular (that is, apparent) size and the galaxy's face-on orientation make it an ideal object for professional astronomers who want to study spiral arm structure and spiral density waves. It is estimated that M74 hosts about 100 billion stars. Observation history M74 was discovered by Pierre Méchain in 1780. He then communicated his discovery to Charles Messier, who listed the galaxy in his catalog. In July 2022, it was observed by the James Webb Space Telescope, not long after it began taking its first pictures and observations and soon astr ...

M202A1 FLASH
The M202 FLASH ("Flame Assault Shoulder") is an American rocket launcher manufactured by Northrop Corporation, designed to replace the World War II–vintage flamethrowers (such as the M1 and the M2) that remained the military's standard incendiary devices well into the 1980s. The XM202 prototype launcher was tested in the Vietnam War, as part of the XM191 system. Description The M202A1 features four tubes that can load 66 mm incendiary rockets. The M-74 rockets are equipped with M235 warheads, containing approximately 1.34 pounds (610 g) of an incendiary agent. The substance, often mistaken for napalm , is in fact TPA (thickened pyrophoric agent). TPA is triethylaluminum (TEA) thickened with polyisobutylene, in the presence of n-hexane, preventing spontaneous combustion after the warhead rupture. TEA, an organometallic compound, is pyrophoric and burns spontaneously at temperatures of 1600 °C (2912 °F) when exposed to air. It burns "white hot" because o ...

M74 Armored Recovery Vehicle
The M74 tank recovery vehicle (M74) was an engineer vehicle used by the U.S. Army in the 1950s. It was designed to cope with the heavier weights of the M26 Pershing and M47 Patton. It could also be suitable for light dozing, since it had a hydraulic, front-mounted spade. More than 1000 were produced by Bowen-McLaughlin-York by converting M4A3 Sherman tanks starting in 1954. Later, some were converted from M32B1 ARVs by Rock Island Arsenal until 1958. Development After the Korean War the M74 was designed to cope with the heavier weights of the new vehicles that were being introduced. Designed in 1953, it was based on the M4A3 HVSS medium tank and it was developed to cope with the heavier M26 Pershing and M47 Patton tanks which were entering service, which the M32 Armored Recovery Vehicle (ARV) was unable to retrieve. Using the standard Ford GAA and wide tracks, the chassis would be rebuilt. It was replaced in service with the U.S. Army by the M88 Hercules. Design The M74 w ...

M-74 (Michigan Highway)
M-74 was the designation of a state trunkline highway in the US state of Michigan. The highway ran through rural Missaukee County connecting Pioneer with Merritt. The highway was designated by 1919 along a longer route. It was shortened before it was totally removed from the highway system in the late 1930s. The Missaukee County Road Commission initially refused to accept jurisdiction over the roadway and refused to maintain it leading to a legal fight with the state highway commissioner. Route description M-74 started at a junction with M-66 near the community of Pioneer. It ran east on Moorestown Road through Stittsville to Moorestown before turning south on Nelson Road. There it ran through the community of Star City, turning west briefly on Walker Road and running south on Star City Road before terminating at a junction with M-55 west of Merritt. All of M-74 was a gravel highway. History On July 1, 1919, M-74 ran between Pioneer and M-55 west of Merritt. There it turned ...
