.....There were only plans to build ships with 20 inchers,but none were ever built. The largest guns were 18.1 inchers on the Yamato and a sister ship.
 
That's called the Coriolis Effect. Beyond around 1000 yards it has to be taken into account, and the extent of the effect also depends on the direction you are firing. Ballistic computers do all those compensating aiming calculations. Back during WWII such computers existed aboard the ship but they were mechanical, not electronic, with lots of gears, screws, and cams. It was quite an art, and it took considerable skill, to operate them.

Never got the blue screen of death, however...
 
I read that....

"The Norden bombsight is another WWII era device that is jaw dropping in its precision and complexity."

It was another mechanical computer which took into account airspeed, wind speed, altitude, etc., and even the type of bomb being dropped. However it produced nowhere near the accuracy on target as legend has described it. During WWII the Norden bombsight was treated as ultra top secret, but in fact the Germans already possessed drawings of it, obtained by a Nazi spy working at the plant. Most of the bombings of German targets was simply mass random bombings from a large number of aircraft. A flight leader would drop his bombs on target as best as he could aim on it (sometimes guided by flares dropped from pathfinder aircraft if it was a night mission), and all the other planes in the flight would drop their bombs at the same time without aiming for the most part. The bombing process was very inefficient but ultimately somewhat effective.

...Curtis Lemay changed the tactics (one being the 'tight box formation') at at the time the air war was changing with the advent of long range escort fighters. That way it only took 8 missions to destroy a target rather than 10.:confused:
 
Sorry for thread drift but I understand 8" howitzers used tubes like the Navy 8" guns.

Dad served with 780th FA Battalion during the Korea War. 8" towed howitzers. Often talked of fire missions of up to 20 miles. 200 lb. shell. Once they mounted an 8" tube on a tracked vehicle and pulled it up a narrow mountain road in winter to use it for direct fire to take out a Chinese command bunker compound on an opposite ridgeline. Story can be found on-line. They had heard a similar thing had been done in WWII during city fighting in Germany.

Some pictures of 8" Howitzers in action in Korea in 1951. Note size of the shell in one picture. Two men held it up to the breach on a rack and the others pushed it into the tube.

I have a round for that :).....dont worry its empty...at 165lbs

I can't speak to the range but I can dang sure testify to how loud they are!! I crossed the international dateline 3 times on troop ship. On one trip the ship was armed and the had a little practice while we out in the middle of the pond. I don't know what size they were firing but there was no getting away from the noise. I believe to this day that my permanent hearing impairment is due in part to that experience. too much noise!!!!

Many know that the use of escort fighters relied on belly fuel tanks on P-51s to get adequate range to escort bombers into the interior of Germany. Many more may not know that the person responsible for developing the belly tank was Cass Hough (who I think was a USAAF Colonel at the time), the president of the Daisy Manufacturing Company.
 
So why didn't the Battleship 16" guns knock out the big bunkers at Omaha beach that are still there?

Battleships that served at Normandy were USS Arkansas, USS Texas, USS Nevada, HMS Warspite, HMS Ramillies and HMS Rodney. Only the HMS Rodney carried 16 inch guns;

USS Arkansas = carried twelve 12 inch guns
USS Texas = carried ten 14 inch guns
USS Nevada = carried ten 14 inch guns
HMS Warspite = carried eight 15 inch guns
HMS Ramillies = carried eight 15 inch guns
HMS Rodney = carried nine 16 inch guns
 
You haven't lived until you watch a well trained crew operate a Gun Fire Control Switchboard.

Amazing that a mechanical device can compensate for all of the variable of the Fire Control problem.

The HMS Nelson was also there, but it didn't see action until June 10. It was the sister ship to the Rodney. That was an interesting class of battleship. And both were extensively used during WWII, so much so that both were basically worn slap out by the end of the war and scrapped pretty soon after the war.
 
The 155mm howitzers I built for the us Army have a 30 mile 55 gallon drum accuracy. But decades later they been modified in the sand box.

There were two types of shells for the 16" naval guns.The armor piercing shell was called the common shell by the Navy and it had the smaller charge of HE someone listed above. The charge was Explosive D, also known as Dunnite or picratol because it was made from picric acid. It was used because it is very insensitive to shock, a characteristic required for an armor piercing projectile. The other shell was the high capacity shell which a much larger charge of explosive. Both types used a base fuze, and the HC could also have a nose fuze. The actual shape of the shell was very blunt in the case of the AP projectile, with a thin steel nose cap to give it a streamlined profile. Inside of the nose cap was a dye packet and each battleship had a different color dye so that spotters could tell which ship had fired a particular round.
During the VN war, the US Army developed an antipersonnel round for the USS New Jersey that contained 400 bomblets. The Navy found a stock of 16" HC projectiles that had never been loaded, and Picatinny Arsenal bored out the interior to a straight cylinder, then loaded 400 M 43 bomblets and pressed in a baseplug. The charge that expelled the plug and bomblets was smokeless rifle powder. The last problem that had to be solved was the fuze that expelled the bomblets. The Navy had no suitable fuze, and the only fuze the Army had was one for the 175mmmgun that had a maximum time of 200 seconds, which was less than the max time of flight of the 16" gun, and restricted the range to 23 miles. The 16" shells were built and shipped to VN for the New Jersey and worked quite well.

The Nelson Class battleships were interesting in that they had all their main battery forward of the superstructure. I think they were the Royal Navy’s only 16” battleships. The Royal Navy seemed to favor 15” guns on most of their ships. Their last battleships, the King George V class, used 14” guns in quad turrets.
 
In the 1980's (I think) the Navy ordered a friend of mine to have modern steel barrels for the 16" guns made. There was not one foundry in the world capable or interested in casting them, nor is any of the rifling machinery left! So for the last few deployments the battle wagons went out without their huge gun turrets!Ivan


I think if you do a bit of research you will find the reason the Iowa Class battleships did not use their turret guns during deployments after 1989 was a result of what is referred to as "The Iowa Accident". This was the explosion in the #2 turret of the Iowa during gun drill where the propellant charge was somehow ignited before the breech of one of the guns was closed and locked. This resulted in the deaths of several crew members in the turret. Officially the cause is still undetermined. The undetermined classification was the reason the Navy ordered firing of the 16" turret guns be discontinued!

The King George V class were the last class that came out in WWII. The Brits finished off one more battleship after the war was over, the HMS Vanguard. It was gunned with the BL 15" guns in a more conventional 4x2 arrangement instead of the 2x4x4 arrangement of the KGV ships.

Firing 16" rifles was not discontinued for long. Turret "explosions" were not rare. No navy stopped using all their battleships after having one. The USS Mississippi comes to mind as having been the least lucky. Powder burning in her #2 turret killed 44 sailors 6/12/24 then another 43 sailors while bombarding Makin Island 11/20/43. Her other three turrets continued the bombardment without missing a beat. While USS Iowa was decommissioned approximately 18 months after her April 1989 #2 turret flash back killed 47, USS Missouri and USS Wisconsin used their 16" rifles supporting the liberation of Kuwat Jan.-Feb. 1991.
