ABSTRACT The Hellenic Navy is confronted with a set ofmission-related challenges that can not be efficiently supported by existing information systems. However, the transition to more modern information systems needs to fulfill a basic principle ofcommand and control, "unity of purpose". This thesis uses the unifying concept ofinformation architectures to identify some desired characteristics for future HN information systems. Two real-life projects are reviewed to substantiate the analytical suggestions borrowed by the client-network, or network-centric architectural paradigm. The "SeaNet" project is used to show the feasibility and utility of extending internet technologies to the maritime environment. The "Battle Force e-mail" project is presented as a pilot program for the introduction ofTCP/IP based data exchange between units at sea. At the concluding Chapter, a set ofrecommendations is made for the transition to a network-centric information architecture for the Hellenic Navy and the development ofinternetworking capabilities over seawater. 14.

INTERNET AT SEA FOR THE HELLENIC NAVY Panagiotis Lymbens Lieutenant, Hellenic Navy B.S., Hellenic Naval Academy, 1986 Submitted in partial fulfillment ofthe requirements for the degree of MASTER OF SCIENCE IN SYSTEMS MANAGEMENT from the NAVAL POSTGRADUATE SCHOOL March 1997 \ I'm.03 ABSTRACT The Hellenic Navy is confronted with a set of mission-related challenges that can not be efficiently supported by existing information systems. However, the transition to more modern information systems needs to fulfill a basic principle of command and control, "unity of purpose". This thesis uses the unifying concept of information architectures to identify some desired characteristics for future HN information systems. Two real-life projects are reviewed to substantiate the analytical suggestions borrowed by the client-network, or network-centric architectural paradigm. The "SeaNet" project is used to show the feasibility and utility of extending internet technologies to the maritime environment. The "Battle Force e-mail" project is presented as a pilot program for the introduction of TCP/IP based data exchange between units at sea. At the concluding Chapter, a set of recommendations is made for the transition to a network-centric information architecture for the Hellenic Navy and the development of internetworking capabilities over seawater.
