  • 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.

Cool list. But the VTEC comment makes me think that we should do something similar for
the IJN. ;)

I added the Sevast's "C" value earlier today after getting access to my friend's account.
But since he sold all his USN stuff I had trouble determining the "C" value on a properly
set up Sevast due to not being able to actually put guns on it (since the value fluctuates
from displacement to displacement), so I guesstimated and rounded down after some
projecting. I was going to announce the change sometime tomorrow though, since I'm 35k
away from the NC.

Not to nitpick, but it's "VTAKKK just kicked in, yo!"

The Atlanta's "C" value may well be the same as that for the Juneau and Oakland, I'm
simply posting the values as close to preciseness as I could get from my measurements
(which is extremely hard to do given that you only have single tons to work with). But if
you look at the Timmerman vs the Gearing and Gearing DDR, there's no way that a
statistical measurement error would account for that large of a value change. So I'm just
going to play it safe and gather the values for all the ships possible.

-e- Also, I managed to get onto a friend's account last night and measure the "C" values
for the P-cola and Essex, so I added those two values to the table.

I wouldn't be surprised if every single remod has the same C values across the board...
Are you sure your value for the Atlanta (as compared to its remods) isn't simply a
measurement error? It could still be worth it to check that, though...

Bump.

Added the "C" values for the Penn30 and Penn43. Turns out that they have the exact same
"C" values as well. My next stop is going to be the NC in 4 levels, then I'm finally going
to start grinding my SoDak BO towards the Iowa and kill two birds with one stone.

Those are basic maths, did worse in science (Before sunking and going marketing :))
however manipulation of math formula as always been one of the thing I enjoyed doing.
