Musings of a curious individual

A Loud Bang

Naval gunnery is one of the many aspects of warfare that is almost a science in itself. The fact that your artillery piece is now mounted on board ship means that there are a whole new set of problems that need dealing with. It also means that you are no longer tied down to having to move your gun and ammunition wherever you go, instead you get to take the whole fort to where the action is.  I am not going into the mechanics and technicalities of gunnery, I was a mechanised infantryman, and our lives really revolved around our personal weapon and vehicle. 
 
There are three specific examples I am interested in, and they really come from the age of the battleship. When large ships traded fire with equally large ships at long distance. What I find very interesting is the sheer size of these guns, and some of the statistics relevant to them.
 
The first pair are mounted outside the Imperial War Museum in London.
  
The gun on the left came from HMS Ramillies, and was mounted on the ship in 1916 and saw action in 1920 and 1940. It was removed from servce in 1941. 
 
The right hand gun originally comes from HMS Resolution, and was mounted on that vessel from 1915-1938. It was removed and remounted in HMS Roberts, and saw action at D-Day. It was removed in 1945. Both were mounted outside the Imperial War Museum in 1968
 
Both guns are 15 inch and were developed in 1912, seeing service in 22 ships. Each weighs  in at a hefty 100 tons, and fired an 876 kg projectile at a maximum range of 29 kilometres.

The next example I photographed at Fort Nelson near Portsmouth. 
 
 
This example is 14 Inch MK VII, and was made by Vickers-Armstrong in 1946, and is the last of her type. These were destined for ships of the King George V class battleships, although this particular gun  never went to sea. The gun with its counterweight weighed in at 91 tons, the maximum range at 40 degrees elevation was 35,4 kilometres. 
 
 
Projectiles weighed in at 660 kg with a propellant charge of 153 kg of Cordite.  1000 projectiles were taken to sea. 
 

These huge guns are very impressive to see, and when you consider that they were usually mounted in pairs, or triples in a turret (or even a quadruple turret), it makes you wonder what size the ship was!. They were also not the largest guns to go to sea, the Japanese battleships Yamato and Musashi had 9 x 18,1 inch guns and they were the largest of naval artillery ever fitted to a warship.

Fortunately a number of these guns still survive in some form or another, although the United States probably has the largest collection of big guns still around, and I speak under correction but I think 16 inchers are the biggest naval guns still around today. An 18 inch railway gun still survives in Britain and that has been relocated to Fort Nelson where the 14 inch gun is. Unfortunately that happened after I visited the fort in May 2013

Cruisers usually mounted smaller guns, although these were no less deadly than their much bigger sisters. HMS Belfast on the Thames has a wonderful set of turrets mounting mounting 12 x 6 inch guns which gave her quite a punch. Although, taking on a battleship would not have been a good idea.

 

The workings of the turrets and their shell and charge handling equipment is really fascinating to see, but in a static role it becomes almost mundane. In the heat of battle it must have been a totally different story altogether.

Todays modern warships lack the massive gunfire capabilities, but then given their ability to fight it out over the horizon with an opponent using anti-ship missiles, those heavy guns are no longer needed. The capital ship was rendered obsolete by the aircraft and submarine, and with their demise the big gun left centre stage and was relegated to museum piece or as part of a preserved warship.
