  • 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.

I already have several stickies. >_>

Really useful. And generous of your time too. Would be nice a if a mod stickied this.

Slight bumpage.

After getting the Nevada and finally freeing up some space temporarily in my harbor, I was
able to calculate the "C" values for the Alaska, Bogue, and Nevada. As it turns out, the
Alaska has the same exact "C" value as the Guam, but it can go a lot faster because of its
absurdly high overheat ratio (enough to hit the speed cap at-level).

The next "C" values I'm going to obtain are going to be for the Penn30 and Penn43, then
the NC after that. I'll also see about finding some people who have the ships that I don't
have access to so that I can fill out the complete list eventually.

"The only real problems I have right now are for NM30, NM45, Tenn41, and Tenn45,
but I can get those values later on."

I went the Tenn line if you get impatient with your USN BB pokemon.

I'm actually planning to go down the Penn43 line myself, so it's OK. My Portland BO is
level 52 already, so it won't be long before I get Nevada then Penn30 and Penn43. I also
have some friends who still have an un-remodeled Alaska, P-cola, and maybe Sevast, so I
can get those values in rather short order.

The only real problems I have right now are for NM30, NM45, Tenn41, and Tenn45, but I can
get those values later on.

I have access to the Northampton line of ships up to the North Carolina (Penn line). You
want me to figure the C values, LK? I'm a former math teacher so math is not a problem
but I would need to know what I need to do overall.

Thanks for the info LK. I've looked for stuff like this and it's hard to come by. Thanks
for your efforts and let me know if I can help.

Last I checked, Adalbert was working on something to this key. The natural overheat of
your ship has already been worked out; just multiply your base speed by (1 +
(Overheat(ship) * Overheat(engine)). After that, it's all up to your Engys to increase the
overheat speed.

Very nice work.

As a side note, has anyone found a formula for relating the C value, overheat ratio, and
true engineer ability to overheat speed?
