With the 21st Century and the Third Millennium on the horizon, Naval History polled naval historians on what naval events and technological advances had the most profound impact over the past 100 and 1,000 years. In conjunction with the U.S. Naval Academy's 14th Naval History Symposium, a biennial gathering of the world's foremost naval historians, we solicited responses from potential participants in the 1999 program. Following are representative responses, along with a table outlining the results of our poll.
Captain Henry L. Allen, U.S. Navy (Retired)—Virginia Beach, Virginia
- Development of the nuclear-powered submarine, which brought all parts of the world under possible missile attack from an undetectable undersea force.
- Establishment of secure radio transmissions: This afforded command and control almost instant information and guidance of each fleet unit.
