DW - 4 7 Inch Qf Mark Ix Xii

The4 7 inch qf mark ix xiiwere 45-calibre, 4.7-inch (120 mm) naval guns that were used to fire most Royal Navy and Commonwealth destroyers during World War II. After the war, when the destroyers they were placed on were sold off, the guns were sent to many other countries.

These guns replaced the related BL 4.7-inch gun from World War I. Instead of BL silk bags, the rounds were separate QF in metal cases, and the breech mechanism was changed to a horizontal moving block. Mark IX was used on the A-class destroyers of 1930 and most destroyer classes after that, up to and including the R class of 1942, in single mountings CP Mk XIV.

Description Of 4 7 Inch Qf Mark Ix Xii

Long Barrel Gun With Cover

The 4.7-inch (12-cm) QF Most destroyers made in the 1930s and 1940s used Mark IX. The Mark XII was made to be used in twin mountings and was almost similar to the Mark IX. It was slightly heavier and longer than the Mark IX. Other than firing different rounds, both Marks were the same as the previous 4.7" (12 cm) BL. Mark 1.

For submarines, a wet-mount version of the Mark IX was made, but there were only a few in use before regular 4"/40 (10.2 cm) underwater guns took their place. It was obvious that these guns didn't have a DP role during the war, as more British ships were killed by air attack than by any other reason.

It was hard for these guns to do much AA because they needed a tachymetric (predictive) fire control system, and you had to set the HE time fuzes by hand. The CPXXII, the last single mounting made for these guns, had a rammer that was moved by a spring. All the other single mountings had to be put together by hand. There was no RPC gear on the twin installation, but it did have power slamming, power training, and power elevating.

The Mark IX was made up of an A-tube, a jacket that was 80 inches (203 cm) long, and a belly ring. Mark IXA had a free barrel and a breech ring that could be taken off. Mark IX* showed changes in the breech ring and semi-automatic breech, which were first used for trial guns with two parts wound with wire.

Some Mark IX guns were used on destroyers that were built for Argentina, Brazil, and Turkey, but not all of them were sent. Mark IX showed that the breech ring for the CPXVIII fitting was different.

The Mark IX-A was for guns that had their barrels changed to be free and had a breech ring that could be taken off. New open barrel guns called Mark IX**B were different from Mark IX-A in that the breech ring and jacket link were different, and the breech ring could be taken off.

The 4.7 Inch Qf Mark Ix Xii - Historical Significance

The 4.7-inch QF Mark IX XII is a historical gem that shows how military weapons have changed over time and how important they are in deciding the outcome of sea wars. This marine gun is an integral part of history because of its unique features and original design. It will always be remembered as a landmark in maritime battle.

A Weapon Born Of Necessity

The 4.7-inch QF Mark IX XII was first thought of at a significant time in military history when it became clear that improved quick-firing artillery was needed. As military techniques changed, the Royal Navy realized how important it was to have a gun that could shoot quickly and in a variety of ways to attack enemy ships. The Mark IX XII was created to meet this need. It was the right mix of precise engineering and strategic planning.

Adaptation And Upgrades

As the world moved into the time between world wars, the 4.7-inch QF Mark IX XII was changed and improved to keep up with changes in military technology; because of what we learned in World War I, range, ammo, and general ability all got better. These improvements made sure that the Mark IX XII would remain useful, keeping its place as an essential part of the Royal Navy's arsenal.

World War I - A Crucial Player On The Seas

The 4.7-inch QF Mark IX XII was critical in World War I when marine superiority was significant. The accuracy and speed with which the gun could fire were critical in many naval battles, which helped the Royal Navy win.

Interwar Period - Continued Influence And Upgrades

During the years between the wars, the 4.7-inch QF Mark IX XII was updated to make sure it would still work with new military technology; because of what we learned in World War I, range, ammo, and general ability all got better. These improvements made the Mark IX XII an even more stable and long-lasting military asset, keeping it as an essential part of the Royal Navy's arsenal.

Gun Characteristics

When an RN gun was called a C, it could only fire percussion; a D, it could fire both EMF and percussion; an F, it could fire EMF (later type breech block); and a G; it could fire both DEF and percussion.
Other countries' use of Mark IX guns: In 1938, seven modified "G" class destroyers were sent to Argentina. Six "H" class destroyers were being built for Brazil at the start of the war in 1939, and four "I" class destroyers were being built for Turkey. In 1942, Turkey took two of her destroyers, but the Royal Navy put the other eight ships to work for them.
Other countries have used Mark XII guns. In 1942, two "N" class destroyers, the ex-RN Noble (i) and the ex-RN Nonpareil, were given to the Royal Netherlands Navy and renamed RNN Van Galen (ii) and RNN Tjerk Hiddes, respectively.
Since these were all open mounts, bad weather made the ROF numbers above much lower. For example, many of these ships were on Arctic convoy duty during World War II and had to deal with bad weather.
CPXXII had rammers that were driven by springs, which gave them a better ROF. All the other single mountings had to be pushed by hand. They had a higher ROF with the CPXIX twin placement because it had powered ramming. For more information, see the Mount/Turret Data notes below.
