Russian artillery projectiles

feeds@yuku.com (MarkThomason) — Sat, 12 May 2012 21:09:40 GMT

The USN is justly famous for its heavy projectiles of WWII, which in 16" and 8" were 30% overweight from the formula: weight in pounds equals half caliber in inches cubed. It is often mentioned that the British Navy of WWI used heavy projectiles in their 13.5" and 15" guns of 13.8% overweight that worked out very well. In both navies, the weight was compensated by reducing MV, to 2500 fps in the USN 50 cal guns, and ~2400 fps in the RN.

I wish to ask for more...

Explosives questions

Would the detonation of say 20-30 tons of amatol totally destroy a set of locks at the Panama Canal?

US Navy Mark33 Gun Director

feeds@yuku.com (hummermole) — Wed, 26 Mar 2008 05:43:19 GMT

Looking for any information on the layout / procedures / technical data on the US Navy's Mark33 gun director. I have plenty of info on the Mark37 director, but have found a dearth of info on the Mark33. All I know about the Marck33 is that it was a semi-enclosed gun director very similar to the Mk37 except that it lacked any kind of radar, using optics only and had the ballistic computer located in the director as opposed to below decks like the Mk37 director. Any other info out there...

auxillary control on battleships

Was there such a place on battleships? A sort of Emergency Bridge in case the Main Bridge was knocked out?

Engine Room question re US cruisers

Hello,

What machinery or fittings would have had canvas coverings, heavily greased it appears, in US Treaty cruisers's engine spaces?

TIA

Thanks in advance...

What is the largest number of torpedoes a ship has taken and actually survived?

6" cruiser artillery rate of fire

feeds@yuku.com (BoundingMain) — Thu, 21 Feb 2008 02:23:21 GMT

Reading O'Hara's US Naval Actions Against the Axis, and he claims that the 6" weapons on some of the cruisers could put out a round every ten seconds. That sounds pretty high, though I suppose with hoists for ammo and powder it might be at least doable, if only as a burst-rate kind of thing.

Anyone know the real answer?

Thanks,

Bound

Speed and fuel use WW 2

feeds@yuku.com (tangoj2) — Sun, 17 Feb 2008 21:28:00 GMT

I am looking to find any kind of general rule or specification on the increase in fuel use as a warship exceeds its 'economical cruise' speed. The only 'hard hint' I have at this time is the historical record on refueling DDs (based on time at sea) and a brief snip from one book that notes that a "Benson" class DD would cruise 5,580 NM @ 12 kts., but if upping to 20 kts would drop to 3,880 NM.

I'm working up an expanded version of a naval war game...

Old 5"/Mk 17 Turret ring?

feeds@yuku.com (8th AAF Fan) — Thu, 31 Jan 2008 02:17:54 GMT

I was recently visiting a laboratory at the Univ of Arizona, and one of the faculty showed me the turret ring they use to rotate the ~8 ton magnet of their mass spectrometer. On the base was written 5" Mk17 1942, Los Angeles, CA. It was clearly salvaged from a WWII navy ship, and I assume it is the base of a 5" gun as pictured on the website. But ... the ring looks far to large (~15' diameter) to have been the base of what is pictured on the Naval Weapons Website. Could the...

Testing Threads

Theodore has opened up the option to use threads on this page, to see how/if the new feature works (thanks Theodore).

I've opened this topic to give people a post they can play with/experiment on safely, without disrupting any "proper" topics and annoying others.

Destroyer range 1910-1915

feeds@yuku.com (Sachmle) — Wed, 23 Jan 2008 13:35:12 GMT

What would be the typical range for a 1000t light displacement DD from this era? I found some RN DD w/ 3500nm @15kts, but they were listed as "Long range escorts", and that leads me to believe that they are a lttle long legged compared to most. Any input would be wonderful.

navy web request

Could anyone assist re the signal flown in this painting I recently completed. The corvette is warning the ships of a convoy to stay clear while she picks up survivors from a U Boat.

Port Chicago Disaster: any similar calamities?

feeds@yuku.com (emc) — Wed, 14 Nov 2007 01:44:19 GMT

The worst ammunition handling disaster (of which I'm aware) in the US is the Port Chicago disaster. Does anybody have information about comparable calamities in other services? I'm specifically concerned with loading ammunition in port, not the spontaneous (or not) magazine explosions that seem to have blown up a few ships in the early decades of the 20th century.

Elswick gun breech block numbers

feeds@yuku.com (heritagefutures) — Sat, 20 Oct 2007 16:13:09 GMT

Hi all I have just returned from a brief documentation visit to the former Japanese base on Kiska Island in the Aleutians, Alaska, and I am trying to track down the breech block numbers of some Elswick guns that I recorded there. As far as I can ascertain, there are no order books in existence for the period 1895-1914. Thus I am trying to sequence the guns numbers from other known guns. It seems that Elswick just numbered its gun barrels sequentially, irrespective of caliber. Thus I am keen...

Found a 16 inch gun.

feeds@yuku.com (JadeFalcon1701) — Sat, 20 Oct 2007 10:40:25 GMT

Need a little help. The machine I run at work is made from a battleship gun. A 16 inch 45 caliber Mk VIII to be precise. After researching a bit, I've found the Mk VIII's were only used on the Colorado class battleships. I would like to narrow it down to the exact ship it came from. I've ruled out the Washington as she was never completed, but that still leaves three. Unless I'm mistaken, it either came from the Colorado, the Maryland, or the West Virginia. Those three...
