So per Smurfy, IS and Clan AC have the same projectile speeds.

An IS AC, when a trigger is pulled, one projectile will move at the posted speed towards the target.

Similarly in the case of both IS and Clan LB?-X, all the projectiles move at the same speed after the trigger is pulled.

But a Clan AC and Ultra AC, the "projectile" is actually split into 2-5 projectiles depending on the AC class that are fired sequentially.

When referring to projectile speed on Smurfy for a Clan AC or Ultra AC, what exactly is meant by the projectile speed?

A> The speed it takes for ALL projectiles to hit the target. ie. in the same travel time an IS AC20 slug takes to hit a target, all 5 projectiles from a Clan AC20 will hit the target.

B> The speed of each of the projectiles as it leaves the barrel after one trigger pull. ie. a Clan AC20 would take 5 times as long to deal 20 damage vs an IS AC20 as each of the 5 projectiles moves at the same rate as a single IS 20 slug and are fired sequentially.

C> Smurfy is incorrect and IS and Clan AC/UAC do not have the same speed projectiles.

quirks. does the IS mech have an AC projectile speed quirk?

The projectile speed should be the speed of an individual projectile (pellet, slug, whatever). With Clan ACs, every projectile moves at the same speed, there's just a firing delay in between them.

The time to deal damage for, say, an Ultra AC20 would be [distance]/[projectile speed] + 4*[delay]. Anecdotally, it was mentioned in another thread that Ultra AC rounds have about a ~0.15 second delay between volleys.

I think you meant between individual projectiles. The delay between volleys would be the the weapon cooldown.

As was said above, projectile speed refers to the velocity of each individual projectile. In the case of Clan AC's, several projectiles are fired in a row with a slight delay between them, but those projectiles all travel at the same (listed) speed.

Yeah, it's late, words are hard.

It's not complicated at all, OP.

Projectile speed refers to how fast the individual projectiles are when fired. Clan ACs fire in bursts of shells instead of firing single shells, but they all travel at the stated speed.

Inner Sphere mechs, however, sometimes have quirks that modify their AC projectile speeds. You can see that by going to mechlab and hovering the mouse over the mech you want to see the quirks of. A tab will slide into view that shows you the mech characteristics, quirks among them.

Likewise, while Clan mechs don't have such quirks yet (but may eventually have them), targeting computers modify projectile speed as well, speeding them all up. Well, ballistics and PPCs anyway, I don't think missiles are affected.

Taking into account the projectile speed is the velocity of each of the individual projectiles. Also, factor in there is a slight delay between each projectiles.

Smurfy lists the DPS for IS and Clan UAC to be identical.

Given each Clan projectile moves as fast as a single IS slug. The DPS value should change as soon as the target is above 0m away since you have to increase the travel time per projectile.

Example:

Target 650m away.

IS AC20 fires once. Travel time to target.

Clan AC20 fires once. Travel time to target * 5 + 4 * [delay]?

Also, Clan AC cooldown timer does not start until after the last projectile is fired. So the delay between projectiles should be added to the cooldown timer for DPS calculations.

dont you mean it fires 1 burst? an not 1 single slug like IS ac20

[Willard Phule]

Don't forget, Targeting Computers increase the projectile speed for all Clan projectile weapons.

Projectile speed means the flight speed of the projectiles, it has nothing to do with the number of projectiles or how long it takes to fire a full burst.
