Tested concurrently with the Marsh Screw Amphibian was the Swamp Spryte, a tracked amphibian cargo carrier designed for cargo up to 1,000 pounds. All tests were performed with both loaded and unloaded vehicles and consisted of land mobility and maneuverability test; river and bayou swimming; helicopter lifts; land and water speed tests; land and water fuel consumption tests; and vehicle freeboard determinations. It is concluded that the Marsh Screw Amphibian attains its greatest efficiency, and greatest loaded speed (12.5 mph) when operated in extremely soft liquefied mud and is considered to have military potential. The MSA is inefficient when operated over uneven terrain and is not considered to have military potential in this area. Test results show that six combat equipped personnel or 1,000 pounds of loose cargo can be transported over terrains where the vehicle can operate; maintenance time was excessive; the MSA must be transported between operable areas by a special trailer; and it can be carried as an external load by the CH-34 helicopter. |
