best battleship

In our quest to discover the best battleship of World War II, we will examine various attributes of these warships. In this article, I will break down the anti-aircraft throw weights of the various battleships and discover who had the most effective anti-air guns.

The graph is broken down by the throw weight of each battleship’s light and heavy weapons.

  • Light weapons are the smaller, rapid fire machine guns and cannons. (25mm Type 96, 40mm Bofors, etc.)
  • Heavy weapons are the heavier, longer ranged anti-air weapons. (Single purpose anti-air guns, dual-purpose weapons, etc.)

I then added the light and heavy weapon weights together to produce the total throw weight of each battleship. I then organized the results by this total throw-weight per minute.

most effective anti-air guns

A quad 40mm bofors mount onboard a US carrier. This was an incredibly capable weapon and is the main reason for the overwhelming advantage US battleships had in firepower.

The Most Effective Anti-Air guns are not Based Solely on Throw Weight

Probably the most important thing to remember about this graph is that it is simply listing the practical maximum throw weight of each battleship. Their are several other important factors that influence the anti-aircraft capabilities of each battleship. Accuracy, mount train rates, and many other things also heavily influence how effective a ship is at engaging air targets.

most effective anti-air guns
The 6.1″ (155mm) guns of the Yamato class battleships. Though designed to be dual-purpose weapons, they were generally inferior in the anti-aircraft role. They lacked the train and elevation rates to engage aircraft at speed or close ranges.

For instance, prior to World War II, many nations were playing with heavier dual-purpose guns larger than the 5″ (127mm) standard. France and Japan each used guns from 130mm to 155mm. These larger weapons, though more effective in the anti-surface role, were much less effective in the anti-air role. While these larger weapons were capable of providing barrage fire, their inferior train rates and reduced rate of fire made them near worthless in engaging close range aircraft. The heavier round that these larger guns fired make them look more important on the graph.¬†While the battleships Dunkerque, Richelieu, and Yamato all appear high on the graph, this is partly due to the heavier round that these warships fired. Dunkerque for instance, has a notably high throw weight. However, due to the majority of the throw weight coming from her 130mm guns, her anti-air capablilties are actually more inferior than they appear.

Notes:

  1. Each warship class is represented at is peak through the most heavily armed warship of that class. (Example: Tirptiz represents the Bismarck class)
  2. The numbers for each warship class are derived from the “practical” rate of fire rather than the “cyclic” rate of fire. For instance the Japanese 25mm Type 96 has a cyclic rate of fire of 260 RPM. However its practical rate of fire was about 120 RPM due to the complicated reload process.
  3. The numbers are derived at the maximum practical rate of fire. Generally, sustained rates of fire would slowly drop after a few minutes of fire due to crew fatigue or heating issues.

Revisions:

  1. Updated King George V class to follow her 1945 refit. The improvement moved her up to #5 on rankings.
