10 Fastest Warships of WWII (By class)

During World War II, naval warfare saw significant advancements, leading to the development of some of the fastest and most formidable vessels in history. These high-speed naval vessels played a crucial role in various naval operations, ranging from escorting convoys to engaging in intense naval battles. With the need for speed and maneuverability to outwit adversaries on the open seas, nations sought to push the boundaries of naval technology, resulting in the creation of remarkable vessels that would go down in history as the fastest naval ships of their time. Join us as we embark on a journey to list out the 10 fastest Warships of World War II.

[@erichammond9308]

Actually, when it comes to the Mediterranean vs the north Atlantic, it's not seaworthiness, it's range. Mediterranean ships don't have as far to go without a base.

[@DLordSadow]

@@erichammond9308There is that, but you could still make the same sacrifice in range for a ship operating in the North Atlantic. With the ship being intended to ONLY operate in the Mediterranean, you can cut back on ship structure as the hull won’t be subjected to the kind of stresses it would in the Atlantic.

I'm so glad that I spotted the 'Condottieri' Class in the thumbnail to this video, most especially as I make reference to that class, specifically, the Eugenio di Savoia and the Raimondo Montecuccoli, at a post at my Fan Blog for Valérie Čižmárová, 'Bananas For Breakfast'. What was said about the 'Condottieri' Class during this video seems to chime with what I'd read about them - that they were a sort of Mitsubishi A6M of the seas, where prodigious speed and manoeuverability was gained at the expense of being fragile when attacked. Incidentally, it was noticeable that the Kriegsmarine was conspicuous by its absence from this 'Top Ten'. Does that indicate that the Germans set more store by protection by heavy armour rather than by speed?

[@morskojvolk]

@morskojvolk depends on how you look at it. Only 4 were commissioned but BB-65 and BB-66 were officially laid down and named Iowa class battleships. The follow on Montana class (BB-67) were never laid down but many parts were delivered as long leeds items like gun barrels. Part of the Kentucky dose still exist. After a collision damaged the bow of the Wisconsin, they cut the bow offhand repaired the Wisconsin

[@morskojvolk]

@@thomasheyart7033 Sorry, I was being facetious. In fact, there were only four (unfinished vessels aren't counted as part of the class). Interestingly, Not only was the bow used to repair Wisconsin, the main engines from the Kentucky were used in the USS Detroit (AOE-4), the fastest supply/stores vessel ever built for the USN. She was capable of 34+ Kts. Unfortunately, she was a pier queen, lots of maintenance issues.

One thing to remember about Italian speed demons, unlike everyone else, when they did their trails, the ships were at light load, that is they were only carrying fuel, and water, nothing in their magazines.

[@andrewsmall6834]

Fastest of WW2? They're faster than most ships now.

[@novacolonel5287]

They're not. Most modern warship speeds are given as 30+ knots, and if you do the maths the actual top speeds must be incredibly high. Take Yamato, at about 70,000 tons and 200,000 shp for about 30 kts vmax. Now, the gerald r ford class come in at 100,000 tons and the performance stated is 30 kts from 260,000 shp. Checks out, right? But, notwithstanding hull design improvements, keep in mind that the reactors can put out 1,100,000 kw of thermal energy, or about 1,5 m hp thermal. If even half of that can be converted to propulsion power, we're looking at three times the power output of a Yamato. My guess is that, in emergencies, the grf may well be able to exceed fifty knots for a limited time.

[@Britlurker]

@@novacolonel5287 Agree but he did say 'most'. Most of these are speeds pushed to the limit, what counts is everyday cruising speed which will be lower.

Just thought I'd mention for those who are looking at these ships and don't have an intuitive sense of their mass from the pictures-- the Iowa class comfortably outweighs every other numbered ship combined, and nothing like her-- a capital ship-- exists in modern navies. When set against other more comparable battleships, she was a thorougbred racehorse, designed from the outset for speed-- over five knots faster than the next fastest battleship ever made, and faster than the vast majority non-planing navy ships of any size of any navy-- the fact that she squeezed onto this list shows just how few ships had this kind of speed in navies of the period, or indeed of current times. The Iowa class was a ship made for the chase over vast pacific distances, able to elevate her main guns to 45 degrees to take advantage of high-visibility and radar-guided fire control, where other battleships like the Bismarck class could only elevate hers to 30 degrees. All 4 Iowa class battleships that were commissioned are now museum ships, including the Missouri where the Japanese surrender was signed.

To this day, the Iowa-class are the fastest battleships in the world. Their official top speed was actually 33 knots, but USS New Jersey (BB62) broke the speed record of 35.2 knots (which you posted them at) during her reactivation and shakedown cruise during the Vietnam War.

[@RockDocNeal]

The Gridley class destroyers were listed with a top speed of 38.5 knots, but I just read that one of them, the USS Maury, reached 42.8 knots (49.25 mph) during a trial, which is the fastest speed ever recorded for a US destroyer. It's interesting that you never hear anything about the Italian warships of WWII.....I'm assuming it's because most of them ended up on the bottom of the ocean before they had any impact in the war. 🤔 The top speed of the current US nuclear-powered aircraft carriers is classified and only listed as "in excess of 30 knots", but they can easily exceed 40 mph.

[@jameswaterfield]

'C' and 'J', 'K' and 'N' Class Destroyers at 36 Knots (though Cavalier made 40 knots in a race in 1971). Tribal Class Destroyers at 37 Knots to name but a few. Basically, the list has been Rorted to mage the Iowa class Battleship #10, when it very likely isn't even in the to 15.

I notice the narration said there were 6 Iowa class. This is incorrect. Only 4 were completed. There at least 2 more under construction but they were cancelled and eventually scrapped.

[@louislopez55]

I wonder how a speedometer works on a ship. Do they just calculate RPM’s of the screws to knots?

[@martinmarheinecke7677]

No, they use a log. In its original form, it consisted of a board and a line tied with knots at regular intervals. The board was thrown overboard at the stern and remained practically stationary because of the drag. A certain time was measured with an hourglass and the knots on the unwinding line were counted. This resulted in the speed at which the ship moved through the water. A knot corresponded to a speed of one nautical mile per hour. Today the impeller log is common. It consists of the impeller, something like a small ship's propeller, which is made to rotate by the flowing water, and is connected to a speedometer cable. The pitot tube log, a tube at the bow, is used less frequently. The water pressure that is measured increases in proportion to the speed.

[@andrewdennison5700]

@@martinmarheinecke7677 Very nice answer. Adding details about "the "regular interval": The most recent practice used intervals of 47 ft. 3 in and 28 seconds. (If I remember correctly my source was American Practical Navigator H.O. Pub #9 - 1962, AKA Bowditch). The glass was also called a sandglass was purpose built for the short interval of 28 seconds. The most recent practice used intervals of 47 ft. 3 in and 28 seconds. Since setting markers in the log line at any regular interval is not difficult it is surprising to me that the time interval is not something more common like 30 seconds or 1 minute. Then the interval would be 50’ 7.56” or 101’ 3.12”. Perhaps the fractional inches where considered to be a problem, compared to waiting 28 seconds with a modern timepiece?

The German destroyers of the Type 1934 had a maximum speed of 38.7 knots (71.7 km/h; 44.5 mph), but their high-pressure boilers, were an over-complicated design which frequently broke down. The ships of this class were also rather bad seaboats and could reach their top speed only in calm water. Type 1936 destroyers exceeded their designed speed of 36 knots with ease, reaching 39-41.5 knots (72.2-76.9 km/h; 44.9-47.8 mph) They also were more seaworthy than type 1934 destroyers, the stability problem was fixed by reducing top-weight and they had clipper-bows to reduce the amount of water coming over the bow in a head sea. The boilers were improved, but still not very realiable.

You forgot the Russian destroyer Tashkent which can go 39 knots. And also Iowa class battleship full speed is only 33 knots and four of them were build not six.

Originally there were 6 for the class. USS Illinois and USS Kentucky (BB65 and BB66 respectively). Actually, BB65 and BB66 were to be the beginning of the Montana-class battleships, but their pennant numbers were transferred into the Iowa-class after some deliberations, hence why Montana was designated BB67. Unfortunately, they were scraped in the late 1950's after numerous modified plans failed for their near completed hulls. Also, USS New Jersey actually holds the record of a speed of 35.2 knots she achieved during her shakedown cruise when she was reactivated for the Vietnam War.

There is no such thing as maximum speed for a ship. It's usually a theoretical top speed. It is entirely down to the sea conditions. Was the ship fully loaded or lightened? How much armour did it have? How much weaponry was it carrying. Even the number of sailors it needs effects it weight. Everything about a warship is a compromise between, range, weaponry and armour. Since they all affect how fast the ship can move.

No, it is not down to sea conditions. It is governed by the waves the ship generates. In a displacement hull speed is limited by the waterline length. What this means is that as speed increases beyond a certain value, any additional power is split between pushing the water (speed) and lifting the hull, (planing). Hence a ship of say 1000 foot is limited to a top speed of around 43 knots in displacement mode. This is very close to the maximum speed of ships like SS "United States" Those fast destroyers are putting much of their power into lift and not speed.

Condition of hull below waterline clean or encrusted with barnacles sea growth etc

I believe the data in the video was all from the ships high speed trials when they were brand new with clean bottoms, light loads and in calm weather. Under full war load they would of course be a little slower.

@@johnlouisebriggs6252 While your explanation is technically correct you cannot ignore sea conditions. High speed trials are conducted on relatively calm seas. You can't go as fast if you are bashing through 40 foot waves.

[@aleksnight5406]

There is a standard test procedure for the maximum speed of the ship. The state of the sea, the loading of the ship, the modes of operation of machines and so on are prescribed. The procedure is carried out on a specially allocated "measured mile", and the average speed of two runs in two directions of the measured mile is counted. This is done to avoid fraud on the part of the manufacturer and the influence of waves and wind.

Kid please add KM/H next time ☺

Aye matey and knots to you you Bìlge rat

[@aleksnight5406]

Traditionally, the speed of naval ships is calculated in knots (nautical mile per hour). It is convenient for maritime navigation. The nautical mile is 1852 meters.

@@m-ots-w1 I have never understood the meaning of preserving the idiotic imperial system of units of measurement. But a nautical mile has a strict meaning, as does a kilometer. For maritime navigation, a nautical mile is more convenient - it is one minute of the arc of the equator. Whereas a kilometer is 1/40000 of the length of the Paris meridian. Kilometers are more familiar to me on land. There are knots on the water. I've always been annoyed by river measurement measures like miles per hour or km/h. Since you are on the water, be kind enough to measure the speed as it should be for sailors. My grandfather was a military sailor.

[@m-ots-w1]

@@aleksnight5406 it's easier to compare km/h vs knots - so you can see that is the "real" speed in your real life. My grandfather was a pilot in soviet P-39 (Polsh Air Force) and he survived ... until 2017
