  • VTEC just kicked in yo: USN Ship ''C'' Values

A few years later, this table is still incomplete, but the most important values are in
there. With only three ships missing the information, it's largely negligible. So, enjoy.

If any of you have read Adalbert's support guides (which I highly recommend) in Tips and
tactics, you'll notice that under Part 7, there's a formula that you can use to calculate
the base speed for your ship. Unfortunately, because it includes a constant unique to each
ship that isn't listed anywhere, you can't actually calculate the base speed of your ship
without knowing that constant. This constant, the so-called Ship "C" Value, can take a
considerable amount of time to calculate. Luckily for you, I've done the work for you.

The formula that you use to calculate the base speed of your ship is as follows:



where

Speed(base) is the base speed of your ship
C(old) is the Ship "C" Value unique to that ship
SHP is the Shaft Horsepower of the engine being used on the ship
disp is the amount of water (in tons) that the ship is currently displacing


Now, you may notice that this formula is different from the formula that Adalbert uses,
and that I use C(old) instead of simply C. The reason for this is, I'm using Adalbert's
old formula, which was changed while I was gathering data on the ships, and which I
continued to use to gather the data afterwards. Both formulas arrive at the same end
result, just that the new formula is somewhat more precise. But for those of you
interested, the conversion formula between the two Ship "C" Values is as follows:



where

C(new) is the Ship "C" Value used in Adalbert's current formula
disp(std) is the standard displacement for the ship in question
C(old) is the Ship "C" Value in my list

Note that you may lose some precision in the value when converting from the old value to
the new one.

So, finally, here is my current list of Ship "C" Values:

Fletcher - 7.47
Gearing - 8.26
Somers - 8.16
Gearing DDR - 8.38
Timmerman - 6.47
DDX Project - 9.04

Omaha - 11.5
Atlanta - 9.69
Juneau II - 9.7
Oakland - 9.7
Brooklyn - 10.35
Cleveland - 11.12
Texas

O Class - 9.05
S Class - 10.2
Barracuda - 15.91
Cachalot -

Northampton - 7.84
Portland - 8.05
New Orleans - 8.45
Baltimore - 9.265
Pensacola - 10.85

Alaska - 10.8
Nevada - 24.73
Guam - 10.8
New York - 21.35
New Mexico(1930) - 20.703
New Mexico(1945) - 20.708
Colorado - 24.05
Pennsylvania(1930) - 23.28
Pennsylvania(1943) - 23.28
Tennessee(1941) - 23.92
Tennessee(1945) - 24.22
Mississippi -
Sevastapol - 17.58
North Carolina - 14.31
South Dakota - 13.49
Iowa - 10.7267
Montana - 13.45
Nebraska - 15.5635

Bogue - 33.71
Independence - 9.59
Yorktown - 11.1
Essex - 12.01
Lexington - 12.078
Midway - 12.49

To find the base speed of your ship, simply use the first formula as above, input the
values, and round to the nearest whole number. That will be the base speed of your ship.
Note, however, that it gets somewhat vague if your resulting base speed hovers exactly
between two whole numbers, so when in doubt, try to induce measures to reduce the
displacement to move the base speed a bit higher, but if all else fails, round down to be
safe.

One final parting thought: these values are prone to change in resulting patches, with or
without notice, so take these numbers with a few grains of salt.

Well, the problem is that it's extremely convoluted and requires a lot of time with
each ship just to do it manually, let alone to explain. There's a way to get the data
through the use of various file-analyzing programs, but that's not the method that I
used and it might be less-than-kosher anyways.

I'm a bit busy at the moment, but I might make a post about it later.

if you dont mind, would you please share with us the methodlogy to find "c" values for
other nations so other people can explore it.
btw....thanks for your helps

I have a New York and I can test that myself, plus I also have access to the Test
Server so I can check up on stuff there too.

The main stopgap right now is simply that I'm busy and I'm also lazy. :P

LK if you wanna use my account to find other country values, msn me for the
password

Do you still need access to the new york and tennessee lines?

Eh, I already own four of the stickies up top, give me this one and I'll effectively have
written 50% of the stickies in this subforum.

As much as I'd like that, I don't want this stickied just yet, maybe when I finish
publishing all the values. Besides, it's something of a technical post, not many people
would understand it.

You can't, unless somebody else who has those ships crunches the numbers for you.
And since I'm a USN player, I'm not the one who can do this for you, since I'm still a
long way away from getting somewhere on my KM line.

On another note, I should probably input the Iowa's "C" value now that I have it. Oh
well, maybe later...

Well, that was faster than expected.

I just got my NC a few minutes ago and calculated its "C" value. Check the list for it.

-e- Hmm, I seem to have grossly miscalculated something, lemme go back and check it again...

-e2- OK, checked, the value should be right now.
