Destroyers

A destroyer is a fast and maneuverable yet long-endurance warship which is mainly used to escort larger vessels in a fleet of ships or a battle group and also used to defend them agains't smaller and short-ranged attackers.
Destroyers evolved in response to the threat posed by torpedo boats to capital ships. Growing from earlier developments, the first official designation of "Torpedo boat destroyer" as a recognised class of warship.
By the 21st century, destroyers are the heaviest surface combatant ship in general use with just three countries operating heavier class cruisers and no one operating battle ships.
The three nations which have heavier class cruisers are : United States, Russia and Peru.
Modern Destroyers are known as guided missile destroyers which are equivalent in tonnage but vastly superior in firepower to cruisers of World War II.Modern Destroyers are capable of carrying nuclear missiles.
The biggest destroyer is the Arleigh Burke-class destroyers which are more heavily armed than the previous ships classified as guided missile cruisers due to their massive size and armament which is over 90 missiles.
1) Arleigh Burke-class destroyers :
The Arleigh Burke class of guided missile destroyers (DDG's) is US Navya's first class of destroy built around the Aegis Combat System and the SPY-1D multi-function phased array radar. It was named for the Admiral Arleigh Burke, the most famous American destroyer officer of WW2 and later Chief of Naval Operations.

The Arleigh Burke-class destroyers were designed to fit the Anti-Aircraft Warfare.
They're equipped with their powerful Aegus RADAR and anit-aircraft missiles, anti-submarine warfare (ASW), with their towed sonar array, anti-submarine rockets and ASW helicopter, ASUW (Anti-surface warface) with their Harpoon missile launcher and a strategic land strike using Tomohawk missiles.
The Arleigh Burke class is planned to be the third most numerous class of destroyers to serve in the US Navy after Fletcher and Gearing classes.
The US Navy has 62 vessels of the Arleigh Burke- class guided missile destroyers.
They have a length of about 505 feet to 509 feet, displacement ranging from 8,315 to 9,200 tons and weaponry including over 90 missiles.
They're larger and heavily armed when compared to the previous ships classified as guided missile cruisers.
















2)Izumo-class destroyer :

Officially labelled as a destroyer, it has a flat top which will function as a flight deck for helicopters. The vessel has been criticised as a thinly veiled attempt to boost the country's military capabilities.
Japanese officials have insisted that the ship will be used to assist humanitarian missions and large scare evacuations following events like the 2011 tsunami.
It hasn't been officially named but dubbed as Izumo after the armoured cruiser of the Imperial Japanese Navy which was sunk in an air attack in 1945. Length of the Izumo-class destroyer is about 820 feet and a displacement of 27,000 tons. Maximum speed is 30 knots and it has a crew of 970 people.
Armament includes 14 helicopters and anti-submarine warfare.
