CH-53E
The Sikorsky CH-53E Super Stallion is a heavy-lift helicopter operated by the United States military. As the Sikorsky S-80, it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor, and canting the tail rotor 20°. It was built by Sikorsky Aircraft for the United States Marine Corps. The less common MH-53E Sea Dragon fills the United States Navy's need for long-range minesweeping or airborne mine countermeasures missions, and perform heavy-lift duties for the Navy. The Sikorsky CH-53K King Stallion, which has new engines, new composite rotor blades, and a wider aircraft cabin, is set to replace the CH-53E. Development Background The CH-53 was the product of the U.S. Marines' "Heavy Helicopter Experimental" (HH(X)) competition begun in 1962. Sikorsky's S-65 was selected over Boeing Vertol's modified CH-47 Chinook version. The prototype YCH-53A first flew on 14 October 1964.

Sikorsky CH-53K King Stallion
The Sikorsky CH-53K King Stallion (Sikorsky S-95) is a heavy-lift cargo helicopter designed and produced by Sikorsky Aircraft. The King Stallion is an evolution of the long running CH-53 series of helicopters which have been in continuous service since 1966, and features three uprated engines, new composite rotor blades, and a wider aircraft cabin than its predecessors. It is the largest and heaviest helicopter in the U.S. military. The United States Marine Corps plans to receive 200 helicopters at a total cost of $25 billion. Ground Test Vehicle (GTV) testing started in April 2014; flight testing began with the maiden flight on 27 October 2015. In May 2018, the first CH-53K was delivered to the Marine Corps. On 22 April 2022, it was declared to have passed initial operational capability. Israel has also reportedly ordered the type; other potential export customers include Japan and Germany.

Sikorsky CH-53 Sea Stallion
The CH-53 Sea Stallion (Sikorsky S-65) is an American family of heavy-lift transport helicopters designed and built by the American manufacturer Sikorsky Aircraft. It was originally developed in response to a request from the United States Navy's Bureau of Naval Weapons made in March 1962 for a replacement for the Sikorsky CH-37 Mojave helicopters flown by the United States Marine Corps (USMC). In July 1962, Sikorsky's proposal, which was basically a scaled-up S-61R fitted with twin General Electric T64 turboshaft engines and the dynamic system of the S-64/CH-54, was selected. On 14 October 1964, the YCH-53A performed its maiden flight; the first deliveries of production CH-53s to operational units commenced on 12 September 1966. The first combat use of the type occurred during the following year when it was deployed to the Vietnam theatre; the CH-53 quickly proved its value for moving heavy payloads, particularly in the recovery of damaged aircraft. Several variants of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Minesweeping
Minesweeping is the practice of the removal of explosive naval mines, usually by a specially designed ship called a minesweeper using various measures to either capture or detonate the mines, but sometimes also with an aircraft made for that purpose. Minesweeping has been practiced since the advent of naval mining in 1855 in the Crimean War. The first minesweepers date to that war and consisted of British rowboats trailing grapnels to snag the mines. By ship A sweep is either a contact sweep, a wire dragged through the water by one or two ships to cut the mooring wire of floating mines, or a distance sweep that mimics a ship to detonate the mines. The sweeps are dragged by minesweepers, either purpose-built military ships or converted trawlers. Each run covers between , and the ships must move slowly in a straight line, making them vulnerable to enemy fire. This was exploited by the Turkish army in the Battle of Gallipoli in 1915, when mobile howitzer batteries prevented the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers.

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

CH-47 Chinook
The Boeing CH-47 Chinook is a tandem rotor helicopter developed by American rotorcraft company Piasecki Helicopter, Vertol and manufactured by Boeing Rotorcraft Systems#Background, Boeing Vertol. The Chinook is a heavy-lift helicopter that is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native Americans in the United States, Native American Chinook people of Oregon and Washington (state), Washington state. The Chinook was originally designed by Vertol, which had begun work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Around the same time, the United States Department of the Army announced its intention to replace the Radial engine, piston engine–powered Sikorsky CH-37 Mojave with a new, gas turbine–powered helicopter. During June 1958, the U.S. Army ordered a small number of V-107s from Vertol under the ''YHC-1A'' designation; following testing, it came to be considered by some Army officials to be t ...

Military Transport Aircraft
A military transport aircraft, military cargo aircraft or airlifter is a military aircraft, military-owned transport aircraft used to support military operations by airlifting troops and military equipment. Transport aircraft are crucial to maintaining supply lines to forward bases that are difficult to reach by ground transport, ground or maritime transport, waterborne access, and can be used for both strategic and tactical missions. They are also often used for civilian emergency relief missions by transporting humanitarian aid. Air frames Fixed-wing Fixed-wing transport aeroplanes are defined in terms of their range capability as strategic airlift or tactical airlift to reflect the needs of the land forces which they most often support. These roughly correspond to the commercial flight length distinctions: Eurocontrol defines short-haul routes as shorter than , long-haul routes as longer than and medium-haul between. The military glider is an unpowered tactical air tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M198 Howitzer
The M198 is a medium-sized, towed 155 mm artillery piece, developed for service with the United States Army and Marine Corps. It was commissioned to be a replacement for the World War II-era M114 155 mm howitzer. It was designed and prototyped at the Rock Island Arsenal in 1969 with firing tests beginning in 1970 and went into full production there in 1978. It entered service in 1979 and since then 1,600 units have been produced. The M198 was replaced in US and Australian service by the M777 howitzer. Description The M198 155 mm howitzer weighs less than , allowing it to be dropped by parachute or transported by a CH-53E Super Stallion or CH-47 Chinook. The M198 is a towed howitzer that is transported tail first. The gun tube can be rotated over the howitzer's trail legs to reduce its length, though this requires removal of the muzzle brake, or left in the firing position for faster deployment. When firing, the weapon is lowered onto its baseplate rather than being anchored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibious Warfare Ship
An amphibious warfare ship (or amphib) is an amphibious vehicle warship employed to land and support ground forces, such as marines, on enemy territory during an amphibious assault. Specialized shipping can be divided into two types, most crudely described as ships and craft. In general, the ships carry the troops from the port of embarkation to the drop point for the assault and the craft carry the troops from the ship to the shore. Amphibious assaults taking place over short distances can also involve the shore-to-shore technique, where landing craft go directly from the port of embarkation to the assault point. Some tank landing ships may also be able to land troops and equipment directly onto shore after travelling long distances, such as the . History In the days of sail, ship's boats were used as landing craft. These rowing boats were sufficient, if inefficient, in an era when marines were effectively light infantry, participating mostly in small-scale campaigns in far-fl ...
