The USSR/Russia measures their guns in inches?
0:50 – When did Liberia and Mianmar went to the Moon Ryan?
The US Army used inches up to early 60s. US designed artillery and those adopted from England before or during WWI used inches. The 8” howitzer was adopted in WWI and the later version used in WWII adopted the same designation. It was a British design that the British placed orders with US gun manufactures and when the US entered the war, placed orders for the same howitzer. The 4.2 inch mortar also was derived from the WWI British mortar that the US Army used until the beginning of WW II. The US also adopted French Artillery and those used millimeters. Examples are the 75mm gun and 155mm howitzer and gun. Both were French. The US designed 75mm pack howitzer used ammunition derived from the 75mm gun. So it adopted millimeters. In the 60s the US standardized much with NATO so the 8” howitzer became the 203mm howitzer. So for the US Army inches denote a US or British origin. Millimeter denote French and later European origin. The USN uses inches with legacy guns for easier understanding for Americans.
16 inch is much more intuitive for me- probably not to metric users.
Go back to "Days of Sail." Guns given names. Then Naval guns. weight of Shot e.g. 24 pdr. 32 pdr. I believe the U.S.Navy weight of Shot. Civil War. Royal Navy for so long weight of Shot; then inch's.
R.A.N. now has 5 inch guns. Recently 76m.m. gunn, retired. Stephen
You climbed in there??? wow
Don't know if it's still in the arsenal, but in the Vietnam era the army had an 8 inch howitzer.
I guess I didn't know… thank you!
LOL, the stupid funny unit system is a pain in the ….
A two and a quarter inch Kentucky mountain rifle cannon is measured the proper way.
The metric system makes sense + should apply everywhere
Jimmy Carter wanted to introduce this in the USA (I think), but unfortunately he failed✌
16" or 406mm? Neither. Age of sail tradition holds true for Naval terms. Call them 2700 pounder guns!
The sixteen inch guns are in freedom units. ??
The organization that went to the moon has fully adopted Metric…
How do you clean out those barrels? Is there a long rod with a brush at the end that is moved by multiple sailors or where people actually crawling trough them?
If you really want to mess with people, give the caliber in centimeters. US 16 inch would be 40.6 cm, a 50 cal would .127cm and a NATO round would be .0762 cm.
Would the .85 diameter curator gun also be the 16" gun? Curious minds want to know.
Lets see….. USA 16 inch guns 406mm
IJN 16 inch guns 410mm
British 15 inch guns 381mm
German 15 inch guns 380mm
Yup inches are consistent when it comes to caliber of guns…
Absolutely love the “countries that have been to the moon” statement. Lol
China, India, and Russia have also been to the Moon. "Successfully landed spacecraft".
