PD Escorts not firing

[mckamx (OP)]

I am playing a 5.6 campaign.  I have a battlefleet that includes 22 Gauss turret equipped point defense escorts:

This design is classed as a military vessel for maintenance purposes

I am currently in a battle where I a wading through salvos of 38 size-1 missiles, with a speed of 52500 kps.  The escorts are set to final defensive fire.   All ships are 100% trained.   I am moving away from the missiles, to keep the salvo separation >= 5 s.   Usually, 3 of the escorts engage the incoming and destroy all of the missiles.  However, every once in a while, only 2 escorts engage the incoming, so missiles make it through my defenses.

How does aurora decide how many PD ships will engage the incoming?   If I could get more escorts to engage, I could laugh at 38-missile salvos, but most of my escorts seem to be taking a siesta.

This should probably go in Academy, but taking a quick look at it I don't see anything immediately obvious. Do you have a copy of the event log handy?

I would suggest going with a quad Gauss turret though, as you've only got 1 fire control for 4 single turrets, so the quad will save you some tonnage.

I would suggest going with a quad Gauss turret though, as you've only got 1 fire control for 4 single turrets, so the quad will save you some tonnage.

I though I read in a thread that with 5.6 the turret sizing algorithm changed, so that the size of a Quad turrent = 4 x size of single turret.

I can't quite figure if my engagement issues are an initiative thing or something else.  Earlier versions of the game worked as expected, but lately I've been seeing much larger number of missiles leaking through my point defenses.   If I can't figure out what is happening, I will have to add shields to my escorts, making them larger and more expensive (with the extra armor, engines, etc. that come with being larger).

[metalax]

Precise figures will vary based on you turret tracking speed tech and the tracking speed set for the turret but these are the figures for my mess about max tech game while I wait for 5.7

Single full size gauss turret size: 8.4
4 * 8.4 = 33.6
Quad full size gauss turret size: 32.64

Space saving = 0.96

Note that the saving is only on the part of the turret dedicated to the tracking gear, in the case of a quad turret that is a 10% saving compared with four single turrets.

[sloanjh]

Could you please post screen-shots of the event log from the two cases you described?  They are very important for others to understand what is going on.

Just to be clear, you've got 22 escorts in a single TG, and all of them have their PD set to final defensive fire mode.  They are using the area-defence final fire mode, not the single-ship final fire mode.  In most cases, the first 3 escorts fire on the missiles, at which point all missiles in the salvo have been killed (meaning each escort kills ~13 missiles?).  Or is it 3 randomly selected that fire?  In some cases, only the first 2 (or 2 randomly selected) fire, so you get somewhere between 0 and ~13 leakers.  Do the leakers all hit the same ship, or are they distributed?  Are the 38 missiles one salvo, or are they 38 1-missile salvos?

I remember a case a couple of revs ago (5.4 or 5.5 maybe?) where the information coming from the event log was confusing - IIRC it looked like some beam hits were getting lost, but in fact it was just the meaning of "total number of hits" (or something like that).  That's probably not the case in your situation (since you're taking hits), but it's possible something weird is going on that isn't obvious in the log.

On turrets, my recollection is that the change was the other way.  In the old days, a quad turret was 4x the size of a single.  Steve changed it so quads are more efficient.

The TG contains 22 Chatham IVa's, and various other ships.   The destroyers (Country, Petra classes) are set for Area PD Mode 30.   The escorts (several models of Chathams, including the 22 Chatham IVa's mentioned) are all set to Point Blank PD Mode 3 (group, not self).   Some of the missiles are being killed by the destroyers, but the escorts are killing the bulk of them.

The log does not detail which salvo the escorts are engaging, so there may be some overlap of log entries for salvo 11838 and 11839.   As best as I can determine, several missiles from salvo 11839 hit Audacious 001 (a DDG).

One oddity I note is that the timestamp increments from 09:29:31 to 09:29:36 in the middle of a group of gauss cannon weapon fire.   I would think that all weapons on a single ship and single fire control would fire at the same time.

Slightly different sets of escorts fire each combat round, although there seem to be "favorites" that may be related to either initiative or crew rating.

Leakers always seem to hit a single ship each round.

The salvos in this case are a single salvo of 38 missiles.

[Havear]

Could we have a screenshot? It's hard to make out what's going on there.

[mckamx (OP)]

Unfortunately, time waits for no man, and the game has advanced several game-years from this particular battle.   Next time I see the behavior, I will get screen shots as well as log dumps.

I had similar incident which I put down to my mistake or the incoming missiles passing through the engagement envelope of the gauss cannon before they had the opportunity to fire. I had four groups of ships in the same location, each with a missile armed jump escort cruiser, one escort and three to four cruisers, the two task groups without the fourth cruiser having a fleet scout with active sensors. At least two of the gauss cannon escorts also had active sensors.
I had inadvertently left the jump escort cruisers point defence range set at 68,000 kilometres, the same as the gauss armed escorts.  However it can be seen that when I sorted the engagement range of the jump escort cruisers out they fired at targets about 4 million kilometres out and the enemy missiles never got within range of the gauss cannon. But the first incoming salvos were only engaged by the CIWS on the missile cruiser target.

[HaliRyan]

I had similar incident which I put down to my mistake or the incoming missiles passing through the engagement envelope of the gauss cannon before they had the opportunity to fire. I had four groups of ships in the same location, each with a missile armed jump escort cruiser, one escort and three to four cruisers, the two task groups without the fourth cruiser having a fleet scout with active sensors. At least two of the gauss cannon escorts also had active sensors.

The final defensive fire mode will only target inbound missiles aimed at members of its own task group, so that might be why you weren't having them fire.

Alternatively, it occurs to me that if you had the range set too high the gauss cannons could have tried to fire while out of range of the target missiles and failed (although I don't know, Steve may have accounted for this in the code).

Lastly, if you were set to area defense mode the missiles probably just crossed the entire distance in one 5 second increment, since area mode won't "interrupt" the movement of the missiles in order to fire.

The final defensive fire mode will only target inbound missiles aimed at members of its own task group, so that might be why you weren't having them fire.

Each group had its own escort so that is unlikely.

Alternatively, it occurs to me that if you had the range set too high the gauss cannons could have tried to fire while out of range of the target missiles and failed (although I don't know, Steve may have accounted for this in the code).

I hadn't considered this.

Lastly, if you were set to area defense mode the missiles probably just crossed the entire distance in one 5 second increment, since area mode won't "interrupt" the movement of the missiles in order to fire.

This is what I assumed happened.
