ability to terminate a mission if weather or craft conditions have degraded past the point of mission accomplishment. The Craft
Engineer is responsible for power plant monitoring, is cross trained as a secondary Craft Master in the case that the actual Craft Master becomes incapacitated, is the overall subject matter expert on craft mechanical and electrical systems, and leads/advises all in flight and in mission repairs. The Navigator is over all in charge of plotting safe lanes of travel, making in flight path of travel changes as needed, ensuring on time beach landings, logging weight of equipment moved, and communications with other craft and ground forces. The Deck Engineer is over all in charge of completing in flight and in mission repairs to the craft as needed, cross trains as a Craft Engineer in the case the Craft Engineer becomes incapacitated, leads on deck firefighting evolutions, and aids the Load Master in on-load and off-load of cargo and troops. The Load Master is overall in charge of all deck evolutions, movement of equipment, cargo, and troops during on loading and off-loading evolutions, proper loading of cargo on deck to ensure proper weight and balance of the craft is maintained and craft is level while on cushion, anchoring, mooring, and rigging for tow operations, ensuring proper restraints are used to secure cargo or calculate restrain requitements for unique or mission specific non-standard equipment, maintenance of craft armament, craft armorer, distribution of weapons and ammunition on command of the Craft Master, and acts as the port look out while in flight.

auxiliary generator engines, Auxiliary Power Units (APU), provide craft electrical power.. The craft can continue to operate, at reduced capability, with two engines inoperable, one lift fan inoperable, and one APU inoperable. Main engines are interchangeable for redundancy and ease of maintenance. A Personnel
Transport Model (PTM) can be assembled on the cargo deck of the craft. They can seat 180 troops, 120 combat loaded troops, and can additionally be converted to transport 54 casualties for medical treatment.

As of
September 2012, there were 80 LCACs in the U.S. Navy inventory; 39 LCACs had undergone the SLEP conversion and 7 were in progress and 4 are awaiting induction. The FY 2013 budget authorized 4 SLEP conversions per year through FY 2018. The last of the 72 SLEP conversions will be delivered to the

Maneuvering considerations include requiring 500 yards or more to stop and 2000 yards or more turning radius. The bow ramp is 28.8 ft (8.8 m) wide while the stern ramp is 15 ft (4.6 m) wide. Noise and dust levels are high with this craft. If disabled the craft is difficult to tow.

The craft operates with a crew of five enlisted
Sailors. Crew positions and responsibilities are as follows: Craft Master, Navigator, Craft Engineer, Deck Engineer, and Load Master. The Craft Master is over all in charge of piloting the craft, crew coordination, crew safety, craft safety, and has the

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 (109 °F), and higher) environments, reduced fuel consumption, reduced maintenance needs,
492:
The near-term focus will be on the "C4N" program, to replace the crafts' obsolete equipment. This will focus on replacement of LN-66 radars with modern, high-power P-80 radar systems. Additionally, the SLEP will include an open-architecture concept, relying on modern commercial-off-the-shelf (COTS)

Phase II. Buoyancy box replacement at the
Textron Marine and Land Systems facility in New Orleans, LA, to increase the LCACs resistance to corrosion. Phase II will also include the electronics upgrade of Phase I, until the entire active fleet is outfitted with the new configuration. The new buoyancy

The LCAC's cargo capacity is 1,809 sq ft (168.1 m), slightly less if cold weather kit is installed for winter and Arctic operations. The LCAC is capable of carrying a 60 short-ton payload (up to 75 tons in an overload condition), including one M-1 Abrams tank, at speeds over 40 knots.

In addition to beach landings, LCAC provides personnel transport, evacuation support, lane breaching, mine countermeasure operations, casualty transport, and Marine and
Special Warfare equipment delivery. The four main engines are all used for lift and all used for main propulsion while two smaller

On June 29, 1987, approval was granted for full LCAC production. Forty-eight air-cushion landing craft were authorized and appropriated through FY 89. Lockheed

Initial Operational Capability (IOC) was achieved in 1986. Approval for full production was granted in 1987.
