[3] JEFF A was later modified for Arctic use and deployed in Prudhoe Bay to support offshore oil drilling.

LCACs are transported in and operate from all the U.S. Navy's amphibious-well deck ships including LHA, LHD, LSD and LPD.

Seventeen have since been disassembled or terminated for cost reasons, two are held for R&D, and 36 are in use on each coast at Little Creek, Virginia and Camp Pendleton, California.

A service-life extension program (SLEP) to extend service life from 20 to 30 years for the remaining 72 active LCACs was begun in 2000 and was scheduled to be completed by 2018.

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.

[7] The LCAC's cargo capacity is 1,809 sq ft (168.1 m2), 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 recent years spray suppression has been added to the craft's skirt to reduce interference with driver's vision.

Buoyancy box replacement at the Textron Marine and Land Systems facility in New Orleans, LA, to increase the LCACs resistance to corrosion.

The new buoyancy box will incorporate improvements to damage stability and trim control of the LCACs.

Concurrently NAVSEA also considered additional SLEP options, including an enhanced engine to provide improved operation in excessively hot environments and an advanced skirt that is more reliable and cost effective.

The Navy continued the LCAC Service Life Extension Program in Fiscal Year 2001.

The near-term focus will be on the "C4N" [Command, Control, Communications, Computers, and Navigation] program, to replace the crafts' obsolete equipment.

After the first SLEP LCAC reached its 30 years design service age in 2015, it was to gradually be retired.

In 2019, at which point the inventory of LCACs had fallen to 50, the USN began receiving the new Ship-to-Shore Connector (SSC), the LCAC-100.
