Vertrep
Vertical replenishment, or VERTREP, is a method of supply of seaborne vessels by helicopter. The United States Department of Defense defines VERTREP as: ...the transfer of cargo between ships using helicopters. VERTREP is often used to supplement connected replenishment. Weapons loads, generally limited to 1,800 kg (4,000 pounds), are transferred from the supply ship to the flight deck of the amphibious ship. The decided advantage of a VERTREP is that it can effect replenishment without ship-to-ship connection. History The United States Sixth Fleet had developed VERTREP routines in 1962 with SH-3 Sea King helicopters operating from and . Each ship carried one SH-3. At that time, there was some anticipation that nuclear-powered ships might reduce the need for alongside refueling. ''Altair'' performed the first night VERTREP to an aircraft carrier in 1965. Modern United States Navy VERTREP procedures were initiated from in November 1964. ''Sacramento'' embarked two CH-46 Sea Kn ...

Underway Replenishment
Replenishment at sea (RAS) (North Atlantic Treaty Organization/Commonwealth of Nations) or underway replenishment (UNREP) (U.S. Navy) is a method of transferring fuel, munitions, and stores from one ship to another while under way. First developed in the early 20th century it was used extensively by the United States Navy as a logistics support technique in the Pacific theatre of World War II, permitting U.S. carrier task forces to remain at sea indefinitely. History Concept Prior to underway replenishment, coaling stations were the only way to refuel ships far from home. The Royal Navy had an unparalleled global logistics network of coaling stations and the world's largest collier fleet. This capability allowed the Navy to project naval power around the world and far from home ports. This had two disadvantages: the infrastructure was vulnerable to disruption or attack, and its use introduced a predictable pattern to naval operations that an enemy could exploit. Early attempts ...

Boeing Vertol CH-46 Sea Knight
The Boeing Vertol CH-46 Sea Knight is a medium-lift tandem-rotor transport helicopter powered by twin turboshaft engines. It was designed by Vertol and manufactured by Boeing Vertol following Vertol's acquisition by Boeing. Development of the Sea Knight, which was originally designated by the firm as the Vertol Model 107, commenced during 1956. It was envisioned as a successor to the first generation of rotorcraft, such as the H-21 "Flying Banana", that had been powered by piston engines; in its place, the V-107 made use of the emergent turboshaft engine. On 22 April 1958, the V-107 prototype performed its maiden flight. During June 1958, the US Army awarded a contract for the construction of ten production-standard aircraft, designated as the YHC-1A, based on the V-107; this initial order was later cut down to three YHC-1As though. During 1961, the US Marine Corps (USMC), which had been studying its requirements for a medium-lift, twin-turbine cargo/troop assault helicopter, ...

Sikorsky SH-60 Seahawk
The Sikorsky SH-60/MH-60 Seahawk (or Sea Hawk) is a twin turboshaft engine, multi-mission United States Navy helicopter based on the United States Army UH-60 Black Hawk and a member of the Sikorsky S-70 family. The most significant modifications are the folding main rotor and a hinged tail to reduce its footprint aboard ships. The U.S. Navy uses the H-60 airframe under the model designations SH-60B, SH-60F, HH-60H, MH-60R, and MH-60S. Able to deploy aboard any air-capable frigate, destroyer, cruiser, fast combat support ship, expeditionary transfer dock, amphibious assault ship, littoral combat ship or aircraft carrier, the Seahawk can handle anti-submarine warfare (ASW), anti-surface warfare (ASUW), naval special warfare (NSW) insertion, search and rescue (SAR), combat search and rescue (CSAR), vertical replenishment (VERTREP), and medical evacuation (MEDEVAC). Design and development Origins During the 1970s, the U.S. Navy began looking for a new helicopter to replace the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carrier Onboard Delivery
Carrier onboard delivery (COD) is the use of aircraft to ferry personnel, mail, supplies, and high-priority cargo, such as replacement parts, from shore bases to an aircraft carrier at sea. Several types of aircraft, including helicopters, have been used by navies in the COD role. The Grumman C-2 Greyhound has been the United States Navy's primary COD aircraft since the mid-1960s. History Early United States Navy (USN) recognition of need for a cargo plane capable of carrier landings resulted in airframe conversion of Grumman TBM-3 Avenger torpedo bombers to unarmed seven-passenger COD aircraft designated TBM-3R. Replacement of TBM-3Rs began in the late 1950s. Grumman built a cargo variant of its twin-piston-engined Grumman S-2 Tracker anti-submarine warfare bomber as the C-1A Trader. (Contrary to popular belief, C-130 Hercules was not tested for COD.) In the late 1960s Grumman began production of a cargo variant of its twin-turboprop E-2 Hawkeye Airborne Early Warning aircraf ...

Naval Warfare
Naval warfare is combat in and on the sea, the ocean, or any other battlespace involving a major body of water such as a large lake or wide river. Mankind has fought battles on the sea for more than 3,000 years. Even in the interior of large landmasses, transportation before the advent of extensive railroads was largely dependent upon rivers, canals, and other navigable waterways. The latter were crucial in the development of the modern world in Britain, the Low Countries and northern Germany, for they enabled the bulk movement of goods and raw materials without which the Industrial Revolution would not have occurred. Before 1800, war materials were largely moved by river barges or sea vessels and needed a naval defence against enemies. History Mankind has fought battles on the sea for more than 3,000 years.

Military Logistics
Military logistics is the discipline of planning and carrying out the movement, supply, and maintenance of military forces. In its most comprehensive sense, it is those aspects or military operations that deal with: * Design, development, acquisition, storage, distribution, maintenance, evacuation, and disposition of materiel. * Transport of personnel. * Acquisition or construction, maintenance, operation and disposition of facilities. * Acquisition or furnishing of services. * Medical and health service support. Etymology and definition The word "logistics" is derived from the Greek adjective ''logistikos'' meaning "skilled in calculating", and the corresponding Latin word ''logisticus''. In turn this comes from the Greek ''logos'', which refers to the principles of thought and action. Another Latin root, ''log-'', gave rise to ''logio'', meaning to lodge or dwell, around 1380, and became the French verb , meaning "to lodge". Around 1670, the French King Louis XIV created t ...

Aerial Refueling
Aerial refueling, also referred to as air refueling, in-flight refueling (IFR), air-to-air refueling (AAR), and tanking, is the process of transferring aviation fuel from one aircraft (the tanker) to another (the receiver) while both aircraft are in flight. The two main refueling systems are ''probe-and-drogue'', which is simpler to adapt to existing aircraft, and the ''flying boom'', which offers faster fuel transfer, but requires a dedicated boom operator station. The procedure allows the receiving aircraft to remain airborne longer, extending its range or loiter time. A series of air refuelings can give range limited only by crew fatigue/physical needs and engineering factors such as engine oil consumption. As the receiver aircraft can be topped up with extra fuel in the air, air refueling can allow a takeoff with a greater payload which could be weapons, cargo, or personnel: the maximum takeoff weight is maintained by carrying less fuel and topping up once airborne.

Foreign Object Damage
In aviation and aerospace, foreign object debris (FOD), is any particle or substance, alien to an aircraft or system, which could potentially cause damage. External FOD hazards include bird strikes, hail, ice, sandstorms, ash-clouds or objects left on the runway. Internal FOD hazards include items left in the cockpit that interfere with flight safety by getting tangled in control cables, jam moving parts or short-out electrical connections. The term FOD is used to describe both the foreign objects themselves, and any damage attributed to them. Jet engine design and FOD Modern jet engines can suffer major damage from even small objects being sucked into the engine. The FAA (Federal Aviation Administration) requires that all engine types pass a test which includes firing a fresh chicken (dead, but not frozen) into a running jet engine from a small cannon. The engine does not have to remain functional after the test, but it must not cause significant damage to the rest of the ...

Bell Boeing V-22 Osprey
The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft. In 1980, the failure of Operation Eagle Claw (during the Iran hostage crisis) underscored that there were military roles for which neither conventional helicopters nor fixed-wing transport aircraft were well-suited. The United States Department of Defense (DoD) initiated a program to develop an innovative transport aircraft with long-range, high-speed, and vertical-takeoff capabilities, and the Joint-service Vertical take-off/landing Experimental (JVX) program officially commenced in 1981. A partnership between Bell Helicopter and Boeing Helicopters was awarded a development contract in 1983 for the V-22 tiltrotor aircraft. The Bell Boeing team joint ...
