USN on LCAC

Windows XP bites the LCAC fleet.

May 13/19: 10 MT7 The Navy awarded Rolls-Royce an $8.6 million contract modification in order to procure 10 MT7 marin turbine installation parts kit shipsets for the Landing Craft, Air Cushion (LCAC) 100 class craft. The LCAC 100 will enhance the US amphibious force’s ship-to-shore capacity with a rated load capacity per craft of 74 short tonnes. LCAC-1s have a 60-short tonne-rated payload. The landing craft was originally designated the Ship-to-Shore Connector and is intended to support the rapid movement of Marine expeditionary forces from naval vessels to shore and will be able to tactically deliver personnel and heavy equipment. The LCAC 100 craft consists of four MT7 turbines. The Rolls-Royce MT7 delivers between 4 to 5 MW and shares common core architecture with the AE1107C-Liberty aero engine. The procurement is in support of the Ship-to-Shore Connector Program. An MT7 installation parts kit is one “shipset” consisting of four engine intakes, two right-hand engine exhausts and two left-hand engine exhausts. Work will take place in Indiana and is expected to be finished by January 2021.

Carrying equipment, troops, and/or supplies, the LCAC launches from inside the well deck of an amphibious warship, then travels the waves at high speed, runs right through the surf zone near the beach, and stops at a suitable place on land. Its cargo walks or rolls off. The LCAC returns to the surf to pick up more. Rinse. Agitate. Repeat. LCAC, ashore (click to view full) A total of 91 LCACs were built between 1984-2001, and their design itself dates back to the 1970s. They require regular maintenance, refurbishment, upgrades, and even life extension programs to keep them operational into the future. This free-to-view Spotlight article will covers the program from 2005 forward, tracking contracts and key events.
