Some questions about HCE-ATA, DATA and guns

Hello TonyE. Is it "Aircraft Bombing Tables" and "Stick Hit Table" from "Harpoon 4 - Rulebook (6-12) & (6-13)" modeled at Harpoon Commander´s Edition (HCE)?

We have 10 A-6E Intruder and 5 EA-6B Prowler flying in the same group.

 

Would Intruder´s DATA benefit from Prowler´s jamming power?

 

P.D.: See "Basic gameplay questions about Prowlers" topic to get more information.

Jugasa77, if your question is in regard to H4.1, please post it down there and I'll do what I can to answer it - not to confuse it with HCE here.

 

I've been meaning to dig out my H4.1 lately. ;)

My question is about HCE.

 

I want to know if Prowler´s jamming pods benefit Intruder´s DATA when they are flying together in the same group.

Yes, the Prowler's jamming will help the Intruders get hit by fewer missiles.

How is the hit chance determined for antiship missiles?

If HCE-GameEngine works the same than Harpoon 4...

 

Antiship missiles are affected by jammers and decoys, which take off a penalty from weapon Ph. Jammers & Decoys together get the highest penalty, and decoys gets a penalty higher than jammers. Missile Ph is also affected by target´s size, being a larger target more easy to hit.

No, most of the code in HCE is based on the version 3 paper rules but I haven't looked into the mechanism of dumb bombs. Many of the tables and rules in H4 do help tremendously with understanding HCE, I don't want to suggest something else. I know it isn't using the stick hit table from H4. A better guess is that the game calculates each potential bomb hit individually.

I want to share my own formula to calculate DATA for each new loadout you create in the database.

 

Sounds like a decent way to do. It places more emphasis on weight than I might like but it is simplistic enough to be useable. Shape of ordnance/drop tanks as well as the mounting position will also have a large effect on the real life DATA. It isn't purely an estimate of maneuverability either as the inclusion of jamming indicates, DATA encompasses the signature-based aspects where a 1000lb drop tank might increase the radar signature of the plane much more than a 2000lb iron bomb.

 

just my 2 cents, I like the effort and bounds checking you've undertaken!

All Database info comes from HCDB-081124

Hello TonyE. Here´s an example from Harpoon 4 - Quickstart Rules.

 

 

Moskit DATA: 0.5+1.0+1.5=3.0

+1.0 for missile speed (1000 knots or higher)

+1.5 for terminal maneuvers

NATO Sea Sparrow ATA 4.0 (40% Ph)

Differential=4.0-3.0=1.0, which gives a Ph=(30+10)=40% per missile

 

 

At HCE, what method use firing AAMs when chasing planes, the first or the second? :huh:

 

P.D.: It seems that AAMs use the same method that Mk15 Phalanx CIWS is using instead of method used by NATO Sea Sparrow.

 

HCE uses an approach closer to the Sea Sparrow example for the AAMs when chasing planes. The Phalanx falls into a different mechanism of point defense instead of area defense.

Antiship missiles are affected by jammers and decoys, which take off a penalty from weapon Ph. Jammers & Decoys together get the highest penalty, and decoys gets a penalty higher than jammers. Missile Ph is also affected by target´s size, being a larger target more easy to hit.

 

HCE does not work the same as Harpoon 4 paper; H4 paper is just a good reference for understanding the game and in the case of antiship missiles many of the same flags apply (you noted high speed, terminal maneuvers, both are modelled in HCE). I'm also not going to be examing every line of code in HCE for you (as much as I would like to) because I wouldn;t get any code written. I walked through a DATA example because pboiler went to a large amount of work looking in the platform editor, running tests, and really forming the answer on his own. I thought that merited an in-depth response.

 

Now if someone(s) want to nicely write documentation of all of the models while I look through the code then that is something we'd love to see (contact us at hc3@harpgamer.com).

What do you exactly mean? Do you mean information about platforms?

 

According "Bill Gunston, Guía ilustrada de misiles aéreos modernos, Madrid, 1983":

Walleye I should have a range of 16 miles and Walleye II should have a range of 35 miles.

 

If you want something like this I can send my own database (commondb.res) when I had finished it. It could take me a long time. Where should I send it? ;)

No, he means documentation about how the various calculations and data fields work in the HCE code. Its something we've been sorely needing for a long time.

It was worth a shot. :D

AIM-120D vs C-130

85 (AIM-120D) - 5 (C-130 DATA) = 80 (difference in ATA)

Chance = difference in ATA + 30, therefore 110 = 80 + 30, Chance = 110

Roll the dice, but needn't bother since the chance to hit is 110%

Isn't there always a 5% chance of a miss?

 

I was under the impression that it was a hard-wired value so that there was always a chance of a miss. It might have been in H3, but appears to have been removed in ANW.

There hasn't been such a device in HC since I've seen the code, definitely not in the AAM vs Plane scenario that we're talking about.
