First foray for Dowty into supplying propellers for amphibious military craft – Textron Systems’ Landing Craft Air Cushion (LCAC) represented the most modern amphibious warfare technology and Dowty designed a new propeller concept tailored to it. Favoured by the United States Navy’s Assault Craft Units and the Japan Maritime Self-Defence Force as a vehicle that can traverse snow, marsh, ice, tundra and sand, and is capable of traversing obstacles as high as four feet on land.
