Modern naval tactics are based on tactical doctrines developed after World War II, following the obsolescence of the battleship and the development of long-range missiles. Since there has been no major naval conflict since World War II, apart from the Indo-Pakistani Naval War of 1971 and the Falklands War, many of these doctrines reflect scenarios developed for planning purposes. Critics argue that the collapse of the Soviet Union and the subsequent reduction in the size and capabilities of the Russian navy renders most such fleet-on-fleet scenarios obsolete.
