Abstract: This paper systematically introduces the maintenance of the American landing craft cushion (LACA) in the past 35 years, the structure of the maintenance department of the two LCAC Units (ACU 4 & ACU 5) and the development of the relevant maintenance technologies. It is concluded that the key to maintain high combat readiness availability is the powerful ground maintenance support, which can be developed by fully equipped professional technical personnel, improved special maintenance tools, close cooperation with the specialized factories and accumulated usage and maintenance data, as well as the application of the advanced analytical methods. One of the design objectives of the ship-to-shore connector (SSC), which is the next generation of the LCAC, is to control the life-cycle cost, including the maintenance cost, at the beginning of the design. The system equipment is simplified by using ICAS and CBM based on the experience of LCAC. The key technology and equipment are verified by FCT or by the full-scale test on LCAC66. It will provide reference for the designers.

Key words: landing craft air cushion (LCAC), maintenance hotspot, technology update, combat readiness availability, condition assessment, life-cycle cost, ground maintenance
