it is a missile loaded ship that is much like a missile cruiser, it is bigger than its counterparts, it fires missiles made from shit that can infect a town of people, these missiles are a form of biological warefare used by all leading countries, they were used in the leading sea exercise of 2004
The torpedo boat destroyer later on took over the role of the smaller torpedo boats, performing torpedo attacks on fleets, such as the devastating Japanese attack on the Russian fleet in Port Arthur at the opening of the Russo-Japanese war in 1904, and attacks in the Pacific theatre of World War II.
Destroyers (with a DD hull classification symbol) primarily perform anti-submarine warfare duty while guided missile destroyers (DDGs) are multi-mission (anti-submarine, anti-aircraft, and anti-surface warfare) surface combatants.
The destroyers (as well as frigates) are, as always, the workhorses of the fleet, the former optimised for air defence and the latter for surface and subsurface warfare.
