Since the destroyer was the only surface fleet unit that could effectively locate, attack and destroy a submarine, it was logical that we should develop a destroyer type that would concentrate on the submarine and thereby release destroyers for fleet assignment. Hence, the destroyer escort. By July of 1943, the program was going full blast. No less than sixteen U.S. yards were involved in building DEs. Between February 1943 and the end of the war in September 1945, 563 DEs were built.
Convert kilometers per hour to miles per hour. You are currently converting speed units from kilometers per hour to miles per hour. 1 kph = 0.62137119223733 mph. kilometers per hour.
1 Meter per Second: Meters per second is the base unit for measuring velocity or speed in the International System of Units (SI). Speed is a measure of distance travelled over time, velocity is speed in a given direction. 1 meter travelled over a period of 1 second = 1 m/s.1 Mile per Hour: A distance of one international mile or 1 760 international yards or exactly 1609.344 meters travelled in one hour or exactly 3 600 seconds.1 Mile per hour = 1.60934 kilometers per hour = 0.44704 meters per second (SI base unit). 1 mph = 0.447 04 m/s. Mile per Hour: A distance of one international mile or 1 760 international yards or exactly 1609.344 meters travelled in one hour or exactly 3 600 seconds. 1 Mile per hour = 1.60934 kilometers per hour = 0.44704 meters per second (SI base unit).
