JEFF A was designed and built by The first 33 were included in the FY82-86 defense budgets, 15 in FY89, 12 each in FY90, FY91 and FY92, while seven were included in FY93.
Through 2016, the Navy will look to incorporate other important service-life enhancements: Engine upgrades (ETF-40B configuration) that will provide additional power and lift particularly in hot (43 °C, 110 °F, and higher) environments, reduced fuel consumption, reduced maintenance needs, and reduced lift footprint; Replacement of the buoyancy box to solve corrosion problems, incorporate hull improvements, and "reset" the fatigue-limit "clock"; Incorporation of a new (deep) skirt that will reduce drag, increase performance envelope over water and land, and reduce maintenance requirements.As of September 2012, there are 80 LCACs in the U.S. Navy inventory.
This will focus on replacement of LN-66 radars with modern, high-power P-80 radar systems. In addition, with a machine as expensive and inherently dangerous as the LCAC, sound judgment and decision-making also play an important role. 74 davon sind im aktiven Dienst, die restlichen in Reserve oder Wartung. It provides the capability to launch amphibious assaults from points over the horizon (OTH) from up to 50 nautical miles (93 km; 58 mi) offshore, thereby decreasing risk to ships and personnel and generating greater uncertainty in the enemy's mind as to the location and timing of an assault, thereby maximizing its prospects of success. The ride feels like a plane in high turbulence. The Landing Craft Air Cushion (LCAC) is a class of air-cushion vehicle (hovercraft) used as landing craft by the United States Navy's Assault Craft Units and the Japan Maritime Self-Defense Force (JMSDF).
Unter anderen stärkere und effizientere Triebwerke, ein Zweimann-Cockpit, die Verwendung von leichteren Materialien beim Bau sowie eine höhere Geschwindigkeit und höhere Nutzlast. Concept design of the present day LCAC began in the early 1970s with the full-scale Amphibious Assault Landing Craft (AALC) test vehicle. Lockheed Shipbuilding Company was competitively selected as a second source. The SLEP is planned for a total of 72 craft. The FY 1991 request included full funding for 12 LCACs and advance procurement in support of the FY 1992 program (which was intended to be nine craft). It will have Pilot/Co-Pilot Dual Controls with a smaller crew (5) and a new Command, Control, Communications, Computers & Navigation (C4N) suite. The inventory will remain at 40 until 2026 when the production of SSC LCAC-100s will begin to outnumber the retirement of SLEP LCACs.
Attrition of operators and engineers has dropped from an initial high of 40% in 1988 to approximately 10–15% today.Without a SLEP the first LCAC would face retirement in 2004, based on a 20-year lifespan.
Die LCAC wurden 1980 entwickelt und 1989 im ersten Einsatzverband eingesetzt. After an initial 15-craft competitive production contract was awarded to each of two companies, On June 29, 1987, LCAC was granted approval for full production. Of these 91 LCACs, seventeen have been disassembled for Government-Furnished Equipment (GFE) or otherwise terminated for cost reasons, two are held for R&D, and 36 are in use on each coast at The craft operates with a crew of five. The craftmaster steers with a yoke, his feet are on rudder controls. During the advanced development stage, two prototypes were built. Zugeteilt sind die aktiven LCAC entweder der Die amphibischen Mehrzweckschiffe der US-Marine können je nach Typ (Der große Vorteil der LCAC ist nicht nur die höhere Geschwindigkeit gegenüber normalen Landungsbooten, sondern auch die Tatsache, dass sie etwa 80 % aller Küsten erreichen und Truppen anlanden können, ohne dass diese durchs Wasser waten müssen, im Vergleich zu etwa 17 % bei regulären Booten. The new buoyancy box will incorporate improvements to damage stability and trim control of the LCACs. A number of LCACs are under development and testing at the The USN inventory of LCACs will continue to fall, as the SLEP LCACs are retired, until 2023, when the inventory will reach a low of 40 SLEP LCACs and SSC LCAC-100s.
Es kann so die klassische unsichere Landungszone in der Brandung wie beispielsweise bei den Landungen im Dieses Konzept, schweres Gerät von hoher See bis zu 80 Kilometer weit direkt auf den Strand zu bringen, heißt OTH (Als Weiterentwicklung war das Heavy Lift Landing Craft Air Cushion (HLCAC) mit 144 Tonnen Ladekapazität und einer um 33 % größeren Ladefläche angedacht.
Concerns over escalating training cost, projections for an increased number of LCAC vehicles and crew, and a high attrition rate in training highlighted the importance of developing a more accurate means of selecting candidates. The first units were identified as early as 2007 with commissioning believed to have taken place from 2010 onward. Its high speed complements a joint assault with helicopters, so personnel and equipment can be unloaded beyond the beach in secure landing areas. Operating the LCAC demands unique perceptual and psychomotor skills. The FY 1990 budget request included $219.3 million for nine craft. In addition to beach landing, LCAC provides personnel transport, evacuation support, lane breaching, mine countermeasure operations, and Marine and Special Warfare equipment delivery.The LCAC is a dramatic innovation in modern amphibious warfare technology.
The Type 726 is a standard Landing Craft, Air-Cushioned (LCAC) vehicle uses by the People's Liberation Army Navy (PLAN).
