WW2 US Navy Destroyers: A Look at the Most Powerful Ships of Their Time

During World War II, the United States Navy played a pivotal role in defeating Axis powers. One of the key assets that helped to secure victory were US Navy destroyers. These agile and powerful ships were designed to provide naval artillery support, protect larger vessels against aerial and submarine threats, as well as engage in anti-surface warfare.

In this article, we will take a closer look at what made WW2 US Navy destroyers so effective and why they remain some of the most famous warships in history.

The Power Behind WW2 US Navy Destroyers

US Navy destroyers during World War II were known for their speed, maneuverability and firepower. They typically measured about 340 feet long with a displacement weight around 2000 tons. These ships had four or five main guns ranging from 5-inch to 6-inch caliber with additional smaller anti-aircraft weapons.

One notable example is the Fletcher-class destroyer which was commissioned in June 1942. This class saw extensive action throughout World War II participating in both Atlantic and Pacific theaters of war. With its top speed exceeding thirty knots (around fifty-six kilometers per hour), it was one of the fastest ships during its time.

Comparing WW2 US Navy Destroyer Classes

There were several classes of destroyers used by America during WWII each with varying specifications:


  • Main Guns: five 5-inch/38 caliber guns
  • Anti-Aircraft Guns: ten Bofors or Oerlikon cannons
  • Speed: over thirty-five miles per hour (mph)

Allen-M.-Sumner Class

  • Main Guns : six dual-purpose guns; three twin turrets.
  • Anti-Aircraft Guns : ten Bofors or Oerlikons.
    -Speed : over thirty-three mph


-Main Gun Battery: six 5-inch/38 caliber guns
-Anti-aircraft Battery: eleven Bofors or Oerlikons
-Speed : over thirty-five mph

Advantages of WW2 US Navy Destroyers

One of the key advantages that destroyers had in World War II was their versatility. They were capable of performing a variety of tasks, from escorting convoys to providing fire support for landings. Their speed and maneuverability also made them ideal for searching and destroying submarines.

Another advantage was their ability to pack a significant punch in terms of firepower. The main guns on destroyers could easily engage enemy ships both on the surface and in the air, while anti-aircraft weapons provided defense against aerial threats.

Tips for Understanding WW2 US Navy Destroyers

If you are interested in learning more about these amazing warships, there are several resources available online. For example, there are numerous websites dedicated to naval history which provide detailed information on individual classes as well as other related topics.

In addition, many museums around the world have preserved examples of these impressive vessels so that visitors can experience firsthand what life aboard one would have been like during wartime.

What were the main roles of US Navy destroyers during WW2?

Destroyers played a central role in the US Navy's strategy during World War II. These ships were designed to provide protection to larger vessels such as battleships and aircraft carriers, and they proved invaluable in this regard. They formed an integral part of escort groups that protected convoys from enemy attacks by submarines, mines, and surface vessels.

In addition to their protective duties, destroyers also served as attack platforms capable of delivering torpedoes or gunfire against enemy targets on both sea and land. Their mobility made them ideal for reconnaissance missions too.

US Navy destroyers were deployed in every major theater of the war – from Europe to Africa, Asia-Pacific to the Atlantic Ocean – often operating in very challenging conditions that tested their crews' skills and courage.

How many types of destroyer classes did US build during WW2?

During World War II, The United States built a total of 175 classes (including sub-classes) comprising almost 700 individual ships classified as "destroyer escorts" or more simply "destroyers". Each class had its own specific design features intended for different purposes based on lessons learned from previous engagements with adversaries.

The most common type was known as Fletcher-class which comprised 175 units; these were highly versatile multi-purpose ships armed with five-inch guns plus anti-aircraft weapons suited for all kinds of operations. There was also Sumner-class which included approximately sixty-six ships that had longer-range torpedo tubes than Fletcher class while Gearing-class is another group comprising around ninety-nine vessels outfitted with advanced radar systems capable enough detecting stealthy targets at long distances

What armament did U.S.Navy Destroyer carry during WW2?

US Navy Destroyer carried various armaments according to their roles: Anti-Aircraft Guns (AA) , Anti-submarine weaponry (ASW), Torpedo Tubes(TT), Deck Guns(DG), Depth Charges (DC) and Minesweeping equipment.

The primary weapon of a destroyer was its five-inch guns, which could be used against both surface and air targets. They were also equipped with smaller caliber guns, such as 40mm Bofors or 20mm Oerlikon anti-aircraft weapons for defense against airborne threats like enemy planes or kamikaze attacks. Depth charges were used to destroy submarines by creating underwater explosions while minesweeping gear was essential in clearing mines that might have been laid by the enemy around friendly harbors or on shipping routes.

Destroyers had varied armament loadouts depending on their role during mission deployment. All ships carried torpedoes as well – either launched from fixed torpedo tubes onboard the ship, from racks on the decks themselves; they proved especially effective when engaging larger vessels like battleships where gunfire alone might not work.

How did US Navy destroyers deal with Japanese Kamikaze pilots?

Kamikaze pilots posed a significant threat to US Navy warships during World War II because of their willingness to sacrifice themselves in suicide missions aimed at causing maximum damage to American fleets. Destroyers played an instrumental role in defending against these attacks using various tactics designed specifically for countering them.

One of the most successful countermeasures employed strategic maneuvering techniques known as "radar picket duty." This involved stationing several U.S. Navy escorts out ahead of carrier groups so they could detect approaching aircraft early enough warning time being given back down command chain before any attack occurs . Once detected, these ships would lay down intense anti-aircraft fire using their primary armaments consisting primarily five inch guns along with machineguns firing bullets up towards incoming planes until within range then switching over torpedoes when appropriate

Another defense tactic included employing fighter aircrafts such as F6F Hellcats which are based onboard carriers escorting naval task forces that engaged kamikazes before reaching their target.

Which US Navy destroyers are preserved today?

Several US Navy Destroyers that served during WW2 have been preserved for posterity and are on display in various locations around the United States. These museums offer a unique opportunity to step back in time and experience what life was like aboard these historic vessels.

One example is USS Kidd (DD-661) – an Allen M. Sumner-class destroyer which fought in both Atlantic Ocean and Pacific campaigns before being decommissioned in 1964. The ship now rests as part of a permanent museum located at Baton Rouge, Louisiana along with USS Slater (DE-766), another survivor from World War II; She is one of only nine destroyer escorts left intact out of the more than five hundred built during WWII, currently based at Albany, New York

USS Joseph P Kennedy Jr DD850 another example, also serves as a floating museum docked at Fall River Massachusetts. Other notable ships include USS Cassin Young DD793 located within Boston National Historical Park's Charlestown Navy Yard area or The Battleship Cove Museum where five different retired vessels including two old-school battleships – USS Massachusetts BB59 & Wisconsin BB64 – can be seen up close to appreciate their size enormity while exploring this exciting chapter history
