After the World War II, warships were gradually modernized by including guide-missile weaponry, sophisticated electronics and sometimes nuclear engines, while armor and cannons were slowly losing significance. Perhaps the most important mark of progress was comissioning of the cruiser USS Ticonderoga in 1983, first ship equipped with the AEGIS system. The new ship had the ability to simultaneosly track up to 100 naval and aerial targets within 200 km radius and quickly engage them with weaponry ranging from anti-air missiles, to anti-missile rapid-firing cannons, to anti-ship missiles. Ships of this class comissioned after 1986 also carried Tomahawk cruise missiles, which could be used to attack ground targets up to 2500 km afar.
