Strategic and port studies have largely ignored the importance of nava
l port systems, even though these systems are (1) essential to the pur
suit of strategy at sea and (2) influenced fundamentally by geostrateg
ic decision-making. It is proposed that effective research at the inte
rface between geostrategy and naval port systems can be promoted by re
ference to five interrelated frameworks: strategic, technological, eco
nomic, urban and social, The relevance of these is demonstrated and it
is argued that their combined effect is to reveal that the geostrateg
y-port system interface is considerably more complex and challenging t
han past research has acknowledged, It is on this basis that extensive
further research is justified. (C) 1997 Elsevier Science Ltd.
