The work explores conversion of entire message fields each into a single code word. This report is one of three related reports on the subject of information entropy of messages in the communications of U. S. Navy ships. The entropy as such is the subject of the present report. The companion reports are concerned with utilization of the data derived in this report. The principal conclusions are as follows 1 In a large class of Navy formatted messages, the format carriers about 66 percent of the text, but only 6.5 percent of its information content. Therefore, developing format for other classes of Navy messages is recommended. 2 Navy teletype language has more than 85-percent redundancy compared with asymptotic information content of the traffic therefore, development of information converters is a promising endeavor.
