HELP ME I'm confused

the AMS damage is listened as 3.5dmg - with a range of 120m.
regarding the average handling i expect that the damage of the AMS goes down to zero till 240m.

With 30shots per second....we have a average RoF of 1shot each 33ms.
in 33ms a flight of LRMs made 5m.

Have made some calculation....with the linear damage drop off.
That means without AMS module....the first missile is destroyed after 12 shots that are 60m for the LRM.
Now we have a break for 80m while AMS is tracking the next LRM.
Than 3 shots...15m
again 80m break
AMS start shooting 5m before the missiles impact....so without AMS module you have to move backwards - with at least 10m/s

With module - AMS start shooting 16m earlier...so that the third AMS is intercepted before impact - when standing still.....

What about 2 AMS?
Do they shoot at the same missile - or is that random - sometimes it seams that both AMS doesn't protect your Mech better as a single AMS (could be explained when both fire at the same missile - 3 -4 intercepted missiles vs 6)

Has anybody a clue - how fast the smaller missile packs are fired by a smaller rack?

For example a LRM 20 from a 4missile rack - (5 packages of missiles)

NARC missiles have 3HP each.
LRMs and SRMs have 1HP each.

AMS does 3.5 damage per second, has a RoF of 30, and can lock onto 2 targets a second.

LRMs will cover the 240M range in 1.5 seconds meaning you can kill 3 LRMs per volley if stationary.
If moving away from the missiles, you can get 1-2 more out of it.
2 AMS should double that to 6-8.

SRMs will be about 1 less per volley I think.

This is about right to be honest.
Remember AMS isn't meant to be a hard counter to LRMs, it's meant to take the edge off.

AMS costs 200,000 C-Bills, with each ton of ammo being 2000 C-Bills, people generally have about 1T per AMS,
meaning the whole system is 1.5T and 202,000 C-Bills.

LR Missile Systems + average ammo amounts cost from 100,000 up to 1,000,000 per launcher and weigh up to 15 tons per.
Sure, stopping the small/cheap ones, but it shouldn't be stopping LRM40s or anything.

AMS is most effective when used by everyone, huddled together. If only a few people have AMS on your team, expect its effectiveness to be reduced. :-) A long time ago, when I was still playing, I used to group up with a few folks regularly -- we would have fun making an AMS umbrella (two mechs with double AMS, two mechs with singles). This is particularly effective at reducing damage.

[Karl Streiger]

so the ...a LRM shoot down 5 missiles is a urban legend and it depends how you move during your AMS works.

But what about those split salvos? I don't think that there is a big break (maybe 0.5sec maybe less)
so in case of the CTF-2X 4 missile ripple salvo of a LRM 20 - that are 5 packs of missiles incomming.

Lets think that the AMS is capable of shooting down 4 missiles, before they make contact....but with 0.5sec after the first volley there is the next -> and this time its only 80m away -> so you hit a single...LRM, as well as with the next 3 packages.

In this case the drawback of firing a LRM 20 out of a 4 missile rack - is that you loose 8 instead of 4 missiles. But those remaing volleys of 4x3 LRMs will conect with almost no spread....right - so most damage will hit the CT

Fixed, but otherwise yeah.

Well at 3.5 missiles destroyed per second... You'd have 1.5 seconds from the first responder's example, then 0.5 seconds for each sequential hit. So meet his conditions and then fire and these are your results.

LRM 20 in Cataphract 2X.

Spoiler

LRM 20 comes in. 4 missiles at a time from the current Cataphract 2X.
3.5 missiles in 1 second + 1.75 missiles destroyed in 0.5 seconds. (5.25 missiles destroyed in 1.5 seconds).
Zero hit.
0.5 seconds later (1.75 damage + the 0.25 left over as damage already started here) 2 missiles destroyed.
Two hit.
0.5 seconds later (1.75 + 0 left over as all missiles fired at are gone) 1 missile destroyed.
3 hit.
0.5 seconds later (1.75 damage + 0 left over as all missiles previously fired at are gone) 1 missile destroyed.
3 hit.
0.5 seconds later (1.75 damage + 0 left over for reason above) 1 missile destroyed.
3 hit.
So you hit with 0 + 2 + 3 + 3 + 3 = 11 missiles. At 1.1 damage per missile that's 12.1 damage.

Now, same thing if you stuffed in LRM 20 + an LRM-15. 8 missiles come in at a time for the first 3 volleys, 7 for the fourth, and 4 for the final.

Spoiler

3.5 missiles killed per second + 1.75 missiles destroyed in 0.5 seconds. (5.25 missiles destroyed in 1.5 seconds).
3 missiles hit; one is damaged. AMS hasn't moved on unlike the first scenario, so no left over damage to deal.
0.5 seconds later (1.75 damage) 1 missiles destroyed.
7 hit.
0.5 seconds later (1.75 + 0 left over as all missiles fired at are gone) 1 missile destroyed.
7 hit.
0.5 seconds later (1.75 damage + 0 left over as all missiles previously fired at are gone) 1 missile destroyed. (this volley had 7 as LRM-15 is on its last 3)
6 hit.
0.5 seconds later (1.75 damage + 0 left over for reason above) 1 missile destroyed. (This volley has 4 missiles, LRM-20 has finished firing)
3 hit.
So you hit with 3 + 7 + 7 + 6 + 3 = 26 missiles. At 1.1 damage per missile that's 28.6 damage.

We call this overwhelming AMS. Old-school launchers like the Cataphract 2X can fire as many missiles as tubes * as many launchers share the tubes. So you can squeeze off 8 at a time. They can't spread all that well which is beneficial for you.

But yes. 100% of that damage unless the target twists, will be dealt directly to the CT.

i have no proof, other than my own finding fireing LRMs, but dual ams (two on one mech) seems close to one ams. However 2 ams on 2 different mechs seem about double one ams.

I think 2 ams on one mech, targets the same missle, so tho it's taken out faster the delay between targets make it not double one ams.

[Spheroid]

Dual AMS with max upgrade seems to make you immune to one turret LRM10 salvo.

[IraqiWalker]

If I recall correctly, AMS shoots down 2 missiles per second of fire. So with 2 AMS firing simultaneously, it's 4 missiles per second shot down. As long as you can keep moving and extend the flight time of the missiles, you will shoot down even more. Also, getting the AMS Extended Range module will help you destroy even more Missiles.

[Revorn]

Math by an Medium-Missleboat. (Myself)


No AMS = Niiiiceeeee *giggles*
1 AMS = Meh
More AMS = *Nagnagn* Dare You. Iam useless now.



So, dont forget your AMS.
