Oh, you guys want more?! My bad [:D]
(been busy in RL sorry for the delay [;)])

We will continue with Japan then;
-IJN Suma (BB). Is this one of the two incomplete Yamato-hulls?
-IJN Karyu (BB). Is this the last incomplete Yamato-hull?
-IJN Hizen (BB). The only site I found was in Japanese, and the ships stats did not compute with a turn of the century BB. Anyone know what this is?
-IJN Unebi (BB). Only IJN Unebi I found was a sailing vessel. (too preserve fuel maybe [:D])

-IJN Karyu (BB). Is this the last incomplete Yamato-hull?

Look at post #32 and #35 for answer about this one. I already typed it there [:D].

Well, here is it again, all sum-up for you here :
**********************************
Shinano BB and Karyu BB were layed down in 1940, cancelled in 1942, 63,000 tons, 263 m length, speed 27 kts, max belt armor 15,75 inches, max deck armor 7,48 inches, 2,500 men, same armament as the Yamato (9 x 18.1 inch guns and 6 x 6.1 inch guns).

The "The Illustrated Directory of Warships from 1860 to Present Day" gives more details :
Karyu is the 4th Yamato Class BB laid down. It was never officialy named and was only ever known as "hull 111". It was scrapped in 1942 when only 30% complete.

It also talks about 3 more BBs, one numbered No 797, a standard Yamato class, and No 798 & 799 which would have mounted 6 x 20 inches guns (508 mm).
I think that the first is the Suma.
I think that the first of the 20 inches gun equipped BBs would have been the Hizen.

Both those assumptions are based on ADG data published in the SiF rulebook.
**********************************

Unebi (1942) seems to be the sister ship of Seiki (1943), because they have identical game characteristics. Both seems to be BattleCruisers (BC) rather than pure BB (from their characteristics). Kind of Alaska BC Japanese Counterpart.

The Yamato class BB originally planned for 5 ships: Yamato, Musashi, Shinano, Hull No.111, and Hull No.797

They were named after states of traditional age. Yamato is now Nara prefecture, the capital in ancient era (before eighth century) resided there. Musashi insists of Tokyo Metropolis, Saitama prefecture, and a part of Kanagawa prefecture nowadays. Shinano is now Nagano prefecture, known as the area where the winter Olympic game had been held in 1998.


The name Suma comes from a geographic location near Kobe, in Hyogo prefecture.
Karyu translates to Fire Dragon (see: Ki-201 Karyu “Fire Dragon”)
Hizen was a province in Japan (and was a captured Russian ship considered a battlecruiser by the Japanese)
Unebi is a mountuntain in Yamato province (translated from a Dutch site http://www.uchiyama.nl/ngsiteindexi.htm)

So if they were to follow the naming convention Suma and Hizen could be Hull No.111, and Hull No.797.

No.798 type battleships Displacement: approx. 70,000t normal Speed: 27kt Armament: 6-51cm gun


Just a FYI on the 12 inch gun crusier

The Super Type A Cruiser was planned by the Imperial Japanese Navy in response to the American Alaska class large cruiser. Two ships, designated Hull Numbers 795 & 796, were planned under the 1942 Program. A rough plan, Project 64, was for a ship of similar size and armament to the Alaska class, with nine 12-inch guns in three triple turrets. Project 65, the last basic design, was for a larger ship of about 31,000 standard tons displacement armed with nine 14-inch guns. The secondary armament was to consist of sixteen of the new 100mm dual-purpose guns. Eight 24-inch torpedo tubes were featured in Project 64, but no torpedoes were included in Project 65. Maximum speed was to be 33 knots. Project 65 was Japan's last design for a large, gun-armed warship.

Although planning for these ships reached a more advanced stage than the Super Yamato class battleships, no orders were ever placed with Japanese contractors. After the Battle of Midway construction of all Japanese warships except carriers, destroyers & submarines was reduced to the lowest priority.

World War II
During World War II a fairly complete system was put in place for the naming of ships. The broad categories of names given are:

Aircraft carriers (pre-1943) - Mythical animals/birds
Aircraft carriers (post-1943) - Country/mountain names
Battleships - Country/province names
Battlecruisers and Heavy cruisers - Mountain names
Light cruisers - River names
Training cruisers (post-1940) - Shinto shrine names
Heavy and light destroyer Destroyers - Meteorological names
Light destroyers - Plant names or Meteorological names
Torpedo boats - Bird names
Submarines - Numbers
Submarine tenders - Whale names
Escorts - (post-1940) - Island names
Destroyer Type A (post-1943) - Water (rain, tides, currents) or plant names
Destroyer Type B (post-1943) - Moon, wind, clouds, seasons

So if they were to follow the naming convention Suma and Hizen could be Hull No.111, and Hull No.797.

ADG data in SiF has it that hull 111 is BB Karyu.
My take is that Suma is Hull 797, and Hizen is Hull 798, the BB equipped with 6 x 20in guns.

Well since we are working with mythical ships. I dont see a problem if it breaks the ship naming rules [:)]

Also :

ADG Data about those is the following :
BC Unebi (B-64) was ordered in November 1942, never built, 35,000 tons, 244.6 m long, 33 knots, 8,000 nm at 18 knots, 8 in Belt Armor, 5 in Deck Armor, 8 in Turret Armor, 1,500 men, 9 x 360 mm guns, 16 x 99 mm guns, 12 x 25 mm AA guns, 8 x 13.2 mm AA guns, 8 torpedo tubes of 24 in, 3 aircrafts.

BC Seiki (B-65) was cancelled in 1942, 34,400 tons, 246.2 m long, 34 knots, the rest same as Unebi.

Edit : This is B-65, not B-66.

360 mm / 25 = approx 14 inch guns [:)]

Yes, I know we are saying the same thing here, I just wanted to complete what you wrote.

360 mm / 25.4 mm = 14,173228346456692913385826771654 inch guns [:D] [:D] [:D]

I suppose the guns are 14 inches in real, so the 360 mm must be an approximation, so the right caliber must be 355 mm.

[X(] You meen "gun size" not "caliber". [X(]

100 caliber = 1 inch or 25.4 mm

360 millimeters = 14.173228 inches
360 millimeters = 1417.3228 caliber

So the right gun size must be 355 mm.

100 caliber = 1 inch or 25.4 mm

Um, not to nit pick but I thought 1.00 caliber = 1 inch when speaking of bore size.
Example: .50 cal Machine Gun shoots a half-inch around projectile.

When speaking of naval guns, caliber is the multiple of bore size giving you the lenght of the barrel.
Example: the BB Ohio carried 16" x 50 caliber guns. Length of barrel was 800" or 66.6'

50 calibers = 0.5 inch
7.62 millimeters = 30 calibers

check the site link above

Sorry, this site is wrong. [:(]

To convert from calibers to:
inches, multiply by 0.01.
millimeters, multiply by 0.254

Gunsmith sites are a bit better for this conversion.

Mziln's numbers match your precisely.

From Marrium-Websters online dictionary

2 a : the diameter of a bullet or other projectile b : the diameter of a bore of a gun usually expressed in hundredths or thousandths of an inch and typically written as a decimal fraction <.32 caliber>

Do you say .5 caliber or 50 caliber

Hmmm ...
I believe Mlzin's says:
50 calibers = 0.5 inches
I contend,
.50 caliber = 0.5 inches

That's a 2 decimal place difference or, did I miss something?

ORIGINAL: Mziln
Do you say .5 caliber or 50 caliber

What you say or how it should be written? [:'(]

I say either way works as long as the coversion is correct. I have seen it used both ways.

I say 50 caliber - Fifty caliber

You say .50 cal - Fifty caliber


But common mathmatical usage of fractions says to drop unnecessary zeros.

So you should be saying: point five caliber or pont five zero caliber. Or is the decimal point silent [:D]

The conversion will not be correct if it is 2 decimal places off. [8|]

Again, spoken vs writen.

Now, considering this is naval guns we should be talking about, the point is moot as caliber does not mean the same thing in ship gun terms. [See Post 50 this thread]

About time to go metric ?

And when dealing with naval guns and calibers the decimal point is usualy dropped as in 3"/50 (76.2 mm/50 a destroyer gun) or 460 mm L/45 (18.1"/45 a battleship gun).
