Operation of the U.S. Combat Support Boat (USCSBMK I) on an Ice-Covered Waterway

Abstract

From 15 January through 15 April 1982, the U.S. Combat Support Base (USCSBMK I) was tested on the Connecticut River, in and around Hanover, New Hampshire, to examine its operation on an ice-covered waterway. The objectives were to determine to what extent shoreline ice would affect launch and recovery and if the boat could create an ice-free channel across a river so that a ribbon bridge could be floated. Shoreline ice can inhibit launch and recovery, but several solutions were developed to reduce or eliminate these problems. The boat can, to a limited extent, be used as an expedient icebreaker. It can break competent ice sheets 3.5-4 in. thick as well as significantly thicker thaw- weakened ice sheets. Sheets of well degraded 'end of season' ice up to 13 in. thick were broken.
