What were the most important naval-warfare developments in the decades after the 1930s?
Short answerIntegrated fire control and CICs, then missiles and ASW, satcom, and progressively more integrated data-driven combat systems.
NotesIntegrated fire control and the combat information centre are the choices for the 1940s. The 1950s are treated mainly as a period of bringing existing developments together. Missiles and expanding anti-submarine capabilities dominate the 1960s, followed by satellite communications in the 1970s. From the 1980s onwards, integration and the use of data become the recurring themes. This is a selective outline of bursts of change followed by consolidation. Reluctance to invalidate expensive existing equipment is offered as one reason change can slow between those bursts.
