In a vacuum, muzzle velocity will determine the gun's max range. In real life, it is factored in with shell weight and size for range.

In NF, it is an arbitrary number that reflects historic guns and probably deals with some complicated game code. e.g. a 6" gun with higher velocity than a 16" but much shorter range.

Do not worry too much about muzzle velocity. In BB battles (CA and up) you always want range (L variant guns and Light HE) over damage (Heavy HE) and reload (D guns).

thanks sir.. i guess i wont worry bout it that much now.

muzzle velocity is very important for AA guns.
for example if muzzle velocity is 800-900, you still aim your guidelines infront of aircraft's shadow, like this:

..................................................... | . <-incoming plane
aiming in front of theshadow- | / -direct guidlines aim at the shadow[/QUOTE]

now if muzzle velocity is 500-600 you aim your guidelins WAY more in front of the aircraft's shadow, like this:

..................................................... \ .. <-incoming plane
aiming in front of theshadow- . \ / -direct guidlines aim at the shadow

thus the slower AA gun's muzzle velocity, the more infront aiming is needed = harder / less effective AA.
For example SN's minizni 3.9" dual guns, slow muzzle velocity makes them not that much effective.

As an ordanance officer....Muzzle velocity is a factor in how hard a round hits. The other factor is the weight of projectile.

A hi velocity round...lets say a 5.46 Nato Round with a bullet weight of 62 grains and a velocity of 3100 fps calculates a knockout factor of 6.

However, a ,45 cal with a bullet weight of 540 grains and a slow velocity of 1000 ft fps calculates a knockout factor of 77.
The Nato round travels about Mach 3. The .45 cal round is subsonic yet has tremendous hitting power.

In this case the slow, big dia, and heavy round has 13 times the Hitting power of the smaller high velocity round. Physics doesn't lie. Mass counts.

In theory then, you want a high velocity, heavy round. This will do the most damage. (Can you say Depleted Uranium?)

Don't know if this is the way it works in game physics but in real life..........

1st thing I use MV for is as a measurement of how far the shells are going to travel.

However, it may also be used in calculating how much damage occurs upon impact.

Somewhere I heard that "A given shell (1000 HE) at 800 mps will cause more damage than the same weighted shell at 600 mps. "

Sounds plausible.
