The gearbox is designed for the NAVSEA Ship-to-Shore Connector (SSC). The Lightweight Gearbox is designed utilizing advanced aerospace engineering and state-of-the-art materials. It will provide reliable gearbox operation over the thirty year life of the craft with no Time Between Overhaul (TBO) and minimal maintenance. A two-speed lift system gear train allows for fuel reduction and along with the lightweight design significantly reduces Operations and Sustainment costs. The AVX design has incorporated solutions to NAVSEA Lessons Learned from prior Landing Craft, Air Cushion (LCAC) and SSC Craft. The design team has brought previous design and sustainment knowledge from USMC V-22 and CH-53K drivetrain technology, where weight and reliability are critical, into the program to ensure success.
