A better HR for making G40 SBR dogfight more appealing?

• Down below here is a completely different way of doing SBR for Global 1940

Strategic Bomber in air-to-air combat SBR:
Attack 0
Bombard IC or AB or NB damage: 1D6**+3**

Fighter in air-to-air combat SBR:
Attack 1
Defend 1

Tactical Bomber in air-to-air combat SBR:
Attack 1
Bombard AB or NB damage: 1D6

IC’s AAA: @1 against each Strategic Bomber
Naval Base or Air Base: @1 against each Strategic Bomber or Tactical bomber

• Down below here is a small variant from the above SBR HR for Global 1940
That is my preferred ones, since it is nearer OOB odds.
In this case, both attacking Fighters and Tactical Bombers have a small First Strike advantage over defending Fighter.
However, Strategic Bombers are still defenseless against interceptors.

In this variant, it should be assumed that Tactical bombers can do escorting mission besides Strategic bombers, even when there is no Air Base or Naval Base.

Strategic Bomber in air-to-air combat SBR:
Attack 0
Bombard IC or AB or NB damage: 1D6**+3**
It is a higher rate of damage to compensate for the 0 attack factor.

• Another special rule which can be added to the last new values for StB A0 Damage: 2D6, however I think it would be a major deterrent against attacking SBR is:
Any intercepting Fighters hit must be apply to Strategic bombers first.

That way, even a swarm of Fighters will not be able to prevent bombers from being hit by intercepting Fighters.

This will greatly reduces the odds compared to OOB G40, but this can be frustrating from a defender POV if all StBs are well protected behind a few Fgs which can be use as fodder.

Do you think this could be an interesting rule or not?

This would change these two results:

1 Fighter Attack 1 First Strike and 1 Strategic Bomber Att 0 doing SBR against 2 interceptors Def 1
Interceptors always hit StBomber first.

• Trying to figure out a different SBR which gives Fg interceptor a Defense @2, I’m looking below to see what are the odds of the following combat values:

Strategic Bomber in air-to-air combat SBR:
Attack 1 First Strike
Bombard IC or AB or NB damage: 2D6

Fighter in air-to-air combat SBR:
Attack 1 First Strike
Defend 1

Tactical Bomber in air-to-air combat SBR:
Attack 1 First Strike
Bombard AB or NB damage: 1D6

IC’s AAA: @1 against each Strategic Bomber
Naval Base or Air Base AA gun: @1 against each Strategic Bomber or Tactical bomber

• @Baron:

Basically I never intercept. If Bombers were 0 and Fighters 1 then it would at least force the attacker to send more escorts, or maybe not force but encourage. IDK. I still like the idea of a scrambled fighter reducing a bombers dice roll by two on a 1:1 basis to encourage scrambling. Right now why do it unless you have the advantage?

Yeah, the bombers at 1 really sucks - they should be 0.

Unless I have some advantage in numbers, it seems like intercepting is only giving the attacker more opportunity to damage your force where it counts.

But it all depends on what’s going on in game… and if scrambling that fighter could mean allowing the Russians to place more units - maybe you do it.  High risk game of Russian roulette.

@wittmann:

Afternoon Baron.
I would never intercept, if I had fewer planes than the attacker, unless he had no Fts in the battle and I could afford to lose (could replace) my losses.
As the agressor, I would also ensure I had a Ft to lose, if the defender had Fts which could intercept and would like 2 or 3 more planes than him.
As a rule, I don’t intercept, as the attacker can usually accompany his Bombers, with the canon fodder Fighters.
The new rules make it  a raw deal for the defender. I do not like the change from Anniversary and 42, which saw the 2 in defence become a measly 1 in 1940.

Hi, everyone.
A deeper question for all of you:
would you intercept or make a SBR on 1:1 ratio, if the following values were applied?
Or is this a major deterrent from the attacker POV?

Defending interceptors get first strike @1 and always hit Bombers first, whether Tactical or Strategic (owner’s choice).
If intercepting, the Defender can also bring into combat his AAA units within the TT, each defend @1 against up to 1 plane.

Strategic Bomber in air-to-air combat SBR:
Attack 1
Bombard IC or AB or NB damage: 1D6+2

Fighter in air-to-air combat SBR:
Attack 1 First Strike
Defend 1 First Strike
Always hit Bombers first, whether Tactical or Strategic (owner’s choice).

Tactical Bomber in air-to-air combat SBR:
Attack 1
Bombard AB or NB damage: 1D6

It should be assumed that Tactical bombers can do escorting mission besides Strategic bombers, even when there is no Air Base or Naval Base.

Anti-Aircraft Artillery
Defense: 1 per unit and up to max 1 per enemy’s plane.
All Anti-Aircraft Artillery within the TT get 1@1 up to maximum of 1 defense roll per each attacking aircraft.
Planes’ casualties are the owner’s choice.
AAA unit can be chosen as casualty, if all defending interceptors are already taken as casualties.
If the territory is also under a regular attack, surviving AAA units can also be used against other airplanes, working as per OOB rules.

IC’s AA gun: @1 against each Strategic Bomber
Naval Base or Air Base’s AA gun: @1 against each Strategic Bomber or Tactical bomber

G40.2 SBR HR
Bomber A1 Damage: 1D6+2

Fighter A1 First Strike D1 First Strike

I’m looking for a balance but more historical way of doing G40 SBR.

1. The first thing I got in mind was to simply give all Fgs a preemptive first strike A/D @1.
All Tactical and Strategical bomber keep a regular A1.

Would it be still balance and a good incentive for defender to intercept if the bombers are always the first hit amongst attacking planes?

• OK, everyone. I have some really big statements on a truly better SBR, and not so different from the basics OOB game mechanics.
First a few principles about what can make a good incentive to make SBR or to intercept an SBR attack.

1- A massive number of Strategic Bombers with each an attacking factor @1 is a pretty big deterrent for any TT with fewer Fighter defending @1.
This create an historical aberration in which all air defense stay grounded and let the bombers do the destruction over IC, AB and NB.

2- This situation is created by the fact that intercepting bombers is a worse situation than being bombed up to the maximum damage allowance. Loosing Fighters which can be useful on regular defense (@4) while achieving almost nothing to destroy incoming bombers is also a major deterrent.

3- For an optimized play, on statistical POV, a good player should ponder whether intercepting the bombers really lowering their odds of loosing IPCs over the other way of letting Bombers directly under IC’s AA gun fire. So, a player must calculate how many IPCs will be lost on average if he intercepts against how many direct bombing damage can be done against him.

4- To prevent the fear of massive attacking bombers (acting like fighters attacking enemy’s fighters) most of you people assumed that a Strategic bomber with an attack factor @0 is part of the whole solution. (I agree, so I make a lot of table to find the perfect balance in regard to the usual odds of G40 OOB SBR.)
They should be defenseless in dogfight. But with more destructive power.

5- To see if a given SBR mechanics could work, it should also compare the bare SBR value of Bombers raiding without interference and the TUV lost if a given number of Fighter(s) intercept(s) the bomber. To get an incentive mechanics, the defending player must see a real interest to intercept on a mathematical POV.

Here is the basic OOB reference with a single bomber making an OOB G40 SBR without interference:
1 StB doing SBR without interceptor
Sum: +4.583 - 2 = +2.583 IPCs damage/SBR run

In OOB situation, intercepting with a single Fighter gives lesser damage for the defender.
1 StB A1 against 1 Fg D1 damage: 1D6+2
Sum: + 5.486 - 3.667 = + 1.819 IPC damage/SBR run

And when an escort and an additional interceptor are part of the raid the maths say that it is almost similar to not intercept option (2.583 vs 2.445):
1 StB & 1 Fg A1 doing SBR against 2 intercepting Fgs D1 damage: 1D6+2
Sum: +7.775 - 5.33 = + 2.445 IPCs damage/SBR run

So, on a 1:1 basis, the actual system is broken since their is no real advantage for the defender to risk his precious fighters against such attack.

Here is the first system which I believe can create a better incentive to SBR or intercept without too much turmoil:

Strategic Bomber in air-to-air combat SBR:
Attack 0
Bombard IC or AB or NB damage: D6+3

Fighter in air-to-air combat SBR:
Attack 1
Defend 1

Tactical Bomber in air-to-air combat SBR:
Attack 1
Bombard AB or NB damage: 1D6

IC’s AA gun: @1 against each Strategic Bomber
Naval Base or Air Base’s AA gun: @1 against each Strategic Bomber or Tactical bomber

@Baron:

How can I be convincing? It is needed to compare a few situations between OOB and this new set of values.

First situation, risking a bomber? For the attacker, it is clearly better, the reward is basicaly near 1 IPC higher over OOB (+ 0.8 IPC):
3.417 IPCs/SBR against 2.583 IPCs/SBR.

1 Strategic Bomber doing SBR against no interceptor
Sum: + 5.417 - 2 = +3.417 IPCs damage/SBR
OOB G40: +4.583 - 2 = +2.583 IPCs damage/SBR

Does it worth it to intercept? Of, course there is no risk against any number of bombers. Their attack factor is @0.
On a 1:1 ratio, the attacker can still have better odds (but less than OOB) and there is a chance he can loose the bomber. So intercepting is always better.

1 Strategic Bomber A0 doing SBR against 1 interceptor D1
Sum: + 4.514 - 3.667 = + 0.847 IPC. damage/SBR
OOB G40: + 5.486 - 3.667 = + 1.819 IPC damage/SBR

But, usually the attacker have more tactical options and can choose what will be the ratio he will commit into the SBR. And he can wait a 2:1 ratio by bringing in an escorting Fighter:
1 Fighter A1 and 1 Strategic Bomber A0 doing SBR against 1 interceptor D1
Fg A1 D1 regular: + 7.084 - 3.667 = + 3.417 IPC damage/SBR
OOB G40: + 7.639 - 3.667 = + 3.972 IPCs damage/SBR
This show odds just a bit lower than OOB (a slightly better situation for defender) while the attacking escort provides the casualty buffer needed to make this case at similar odds as a no intercept situation. So, it is up to the defender to choose, both situations are similar: does he believe in his luck or not?

When it is a 1:1 ratio with 1 escort against 2 intercepting Fgs, this new SBR values are much more tempting for an interception (1.6 IPCs vs 2.442 IPCs) and letting the bomber directly attack IC it would rise to 3.417 IPCs/SBR , but still 1 attacking Fighter acting as a casualty fodder is pretty acceptable:
1 Fighter A1 and 1 Strategic Bomber A0 doing SBR against 2 interceptors D1
Fg A1 D1 regular: + 6.933 - 5.333 = + 1.600 IPCs damage/SBR
OOB G40: +7.775 - 5.333 = + 2.442 IPCs damage/SBR

Also, this show that escorting 1 bomber (1.6 IPCs/SBR) gives as much reward than attacking only with bombers (1.693 IPCs/SBR):
2 Strategic Bombers A0 doing SBR against 2 interceptors D1
Sum: + 9.027 - 7.334 = + 1.693 IPCs damage/SBR
OOB G40: +10.973 - 7.334 = + 3.639 IPCs damage/SBR

Only the 2:1 ratio is better with bombers only:
2 Strategic Bombers A0 doing SBR against 1 interceptor D1
Sum: + 9.930 - 5.666 = + 4.264 IPCs damage/SBR
OOB G40: +11.459 - 5.666 = + 5.793 IPCs damage/SBR

but now the defender will not fear to loose his single intercepting Fighter and will commit it to reduce the attackers odds:

2 Strategic Bombers doing SBR against no interceptor
Sum: + 10.834 - 4 = +6.834 IPCs damage/SBR
OOB G40: +9.167 - 4 = +5.167 IPCs damage/SBR

Now, are you convinced that this little twist (bomber A0, +3 damage) will give more dog-fighting situations?

One last word about the chart down below.
It can be used to get pretty good average calculation for more complex situations:
3 bombers and 1 Fgs vs 3 Fgs. This can be obtained with 1 bomber+1 Fg against 2 Fgs and 2 bombers against 1 Fgs:

1 Fighter A1 and 1 Strategic Bomber A0 doing SBR against 2 interceptors D1Fg A1 D1 regular: + 6.933 - 5.333 = + 1.600 IPCs damage/SBR +2 Strategic Bombers A0 doing SBR against 1 interceptor D1 Sum: + 9.930 - 5.666 = + 4.264 IPCs damage/SBR

• 16.863 - 10.999 = + 5.864 IPCs/SBR

Which means: be prepare to loose either a bomber or a Fighter (-11 IPCs) and too inflict around 17 IPCs of damage, probably due to bombing.

Hope this can be found useful somehow.

There is another more challenging way to do SBR, for instance by always letting interceptor hit takes a bomber casualty before any escorting Fgs, but I will explain it on the next post.

• A more historical depiction of SBR which keeps interesting odds compared to G40 OOB.
In this one, intercepting Fighters are targeting attacking Bombers (TcBs or StBs) first, then escorting Fighters.

There is also a combined arms bonus for Strategic bomber in air-to-air combat which is consistent with an older HR invented when talking about Bombers spamming strategies (Darken skies), see down below:

Strategic Bomber
Attack 3-4, gets A4 if paired 1:1 with Fighter
Defense 1
Move 6
Cost 12
Damage 1D6+3.

Tactical Bomber
Attack 4
Defense 3

Strategic Bomber in air-to-air combat SBR:
Attack 0 or 1 when paired 1:1 with Fighter
Bombard IC or AB or NB damage: D6+3

Fighter in air-to-air combat SBR:
Attack 1
Gives +1A to 1 Strategic Bomber when paired 1:1 with.

Always hit Bombers first, whether Tactical or Strategic (owner’s choice).

Tactical Bomber in air-to-air combat SBR:

@Baron:

I like the idea of bomber A3  +1 when paired with a fighter Baron. It’s the same way TACs are used. Also like the idea of fighter intercepts and escorts A2.
The increased range would be bombers greatest asset as well as being able to hit factories.

I also like the  +1 when no enemy planes are present as well.

I believe the right historically inspired rules for them should have been the following, but the StB was too iconic to make such a change:

TACTICAL BOMBER
ATTACK 4
DEFENSE 3
MOVE 4
COST 11
Paired 1:1 with Tank, gives +1D to Tank (an historical point which I kept on defense to counter-balance the Attack @4 in all situations.)
TBR Attack 1 Damage 1D6

STRATEGIC BOMBER
Attack 3 rise to 4
when no enemy’s plane (+1 Attack due to Air Supremacy bonus) or
when paired 1:1 with Fighter

Defense 1
Move 6
Cost 12
SBR Attack 1 Damage 1D6+2

That way, when StBs are attacking a SZ without any Fighter support, then their attack value will be 3 while the defending Fg will keep their high Defense @4.

It will be only when they are paired with 1 Fighter escort per StB, that they can rise to an even combat Attack 4 against Defense @4.

I said more historical combat value because between TcBs and StBs, it seems to me that StBs were much more sitting duck than TcBs. So, it should have been StB which clearly needs a combined arms for Fighter support. Many TacBs types of Fg-bomber or Light-Bomber were able to fly without escort.

Here is what I would prefer as Fg unit to fix the other balance issue in SBR:
FIGHTER
Attack 3
Defense 4
Move 4
Cost 10
Gives +1A to StB when paired 1:1
SBR Attack 2 Defense 2

• Working on the most balanced SBR with Fighter A2 D2, and the winner is…

A more historical depiction of SBR which keeps interesting odds compared to G40 OOB.
In this one, intercepting Fighters are targeting attacking Bombers (TcBs or StBs) first, then escorting Fighters.

There is also a special attack (as an AA gun @1 first strike against up to 2 Fighters) for each Strategic bomber (whichever the lesser number between Fgs or StBs) in air-to-air combat which provides some restriction about Bombers spamming strategies (Darken skies), see above chart for comparisons:

Strategic Bomber
Attack 4
Defense 1
Move 6
Cost 12
SBR or TBR damage 1D6+2.

Tactical Bomber
Attack 3-4
Defense 3
Move 4
Cost 11
TBR damage 1D6.

Fighter in air-to-air combat SBR:
Attack 2
Defend 2
Always hit Bombers as first target, whether Tactical or Strategic (owner’s choice).

Strategic Bomber in air-to-air combat SBR:
Attack 1 first strike* as an AA gun @1 against up to 2 intercepting Fighters, whichever the lesser
Bombard Industrial Complex or Air Base or Naval Base, damage: 1D6+2

Tactical Bomber in air-to-air combat SBR:
Attack 1 first strike
Bombard Air Base or Naval Base, damage: 1D6

IC’s AA gun: @1 against each Strategic Bomber
Naval Base or Air Base’s AA gun: @1 against each Strategic Bomber or Tactical bomber

I will explain sooner how I came to this conclusion.

• Totally different suggestion I have been considering.
Bombers ALWAYS do their +2 damage, even if hit by AAA.
To make SBR more attractive.

You could consider this rule to offset your beefing up of fighters.

From a realistic standpoint it has always been gut-wrenching to send over 2 bombers and get snake-eyed. Knowing that you just sent over probably 1000 bombers and not a single bomb fell on anything important.

The main issue was about making an incentive for dogfight.
OOB G40 bombers are abusive against intercepting fighters.

If you feel the most repelling is the IC’s AA gun, this probably can be work out in the way you suggested, but clearly the attack factor of bomber will be probably zero to not be OP.
I will try to check out how this “D6+2 damage OR only +2 damage” can be calculated and what is a balance mechanics between StBs, escorts and interceptors.

The snake eyes are probably another non-neglectable deterrent aspect which can be most frustrating for attacking player.
A minimum damage sounds like a consolation prize, at least, it let’s the steam out a bit.
Thanks.

Do you also imply when destroyed by interceptors, Bombers can still do +2 damage?

After a fast review, I think I would add your idea as integrated part of the above SBR HR, since it has a small statistical impact (approx. 3,00 IPCs/SBR instead of 2,583 IPCs/SBR.)

I would keep the +2 damage only if hit by AAA exclusively, when an interceptor hit bombers, it is destroyed with no compensation.
That way, it would provide an additional incentive to intercept bombers to wholy protect IC.
And this is a double lever effect.
Attacker will more willingly commit bombers and defender will be more incline to throw fighters against them.
And this is in addition to the fact, that interceptor’s hit must be on bombers first.
It is a much more interesting target.

Working on the most balanced SBR with Fighter A2 D2, and the winner is…

A more historical depiction of SBR which keeps interesting odds compared to G40 OOB.
In this one, intercepting Fighters are targeting attacking Bombers (TcBs or StBs) first, then escorting Fighters.

There is also a special attack (as an AA gun @1 first strike against up to 2 Fighters) for each Strategic bomber (whichever the lesser number between Fgs or StBs) in air-to-air combat which provides some restriction about Bombers spamming strategies (Darken skies), see above chart for comparisons:

Strategic Bomber
Attack 4
Defense 1
Move 6
Cost 12
SBR or TBR damage 1D6+2.

Tactical Bomber
Attack 3-4
Defense 3
Move 4
Cost 11
TBR damage 1D6.

Fighter in air-to-air combat SBR:
Attack 2
Defend 2
Always hit Bombers as first target, whether Tactical or Strategic (owner’s choice).

Strategic Bomber in air-to-air combat SBR:
Attack 1 first strike* as an AA gun @1 against up to 2 intercepting Fighters, whichever the lesser
Bombard Industrial Complex or Air Base or Naval Base, damage: 1D6+2

Tactical Bomber in air-to-air combat SBR:
Attack 1 first strike
Bombard Air Base or Naval Base, damage: 1D6

IC’s AA gun: @1 against each Strategic Bomber
Naval Base or Air Base’s AA gun: @1 against each Strategic Bomber or Tactical bomber

I will explain sooner how I came to this conclusion.

Follow this line in each combat situation (fs= first strike

• @Baron:

Totally different suggestion I have been considering.
Bombers ALWAYS do their +2 damage, even if hit by AAA.
To make SBR more attractive.

You could consider this rule to offset your beefing up of fighters.

From a realistic standpoint it has always been gut-wrenching to send over 2 bombers and get snake-eyed. Knowing that you just sent over probably 1000 bombers and not a single bomb fell on anything important.

Bombers ALWAYS do their +2 damage, even if hit by AAA.
Do you also imply when destroyed by interceptors, Bombers can still do +2 damage?

After a fast review, I think I would add your idea as integrated part of the above SBR HR, since it has a small statistical impact (approx. 3,00 IPCs/SBR instead of 2,583 IPCs/SBR.)

I would keep the +2 damage only if hit by AAA exclusively, when an interceptor hit bombers, it is destroyed with no compensation.
That way, it would provide an additional incentive to intercept bombers to wholy protect IC.
And this is a double lever effect.
Attacker will more willingly commit bombers and defender will be more incline to throw fighters against them.
And this is in addition to the fact, that interceptor’s hit must be on bombers first.
It is a much more interesting target.

2 IPCs even for a destroyed Strategic bomber is not so overpowered, if we consider that SBR should be the main use of Bombers.
In regular combat, a bomber is rarely bring alone. There is usually fodder to fight against ground units.
An attack @4 out of 6 against 1 infantry at 3 IPCs give 4/6*3= 2 IPCs.
This means that a bomber on average is able to destroy 2 IPCs in a single combat, and there is often more than 1 combat round, to the contrary of SBR.

So, there is many interesting good points in your idea oztea, and it doesn’t require to change radically SBR to add into already working optimized SBR values.
The table above showed that even Fgs A2 D2 in air-to-air combat can stay within the, generous, parameters of G40 OOB SBR.

• Nice work Baron. Good idea on the +2 Oz. I wonder if the interceptor hitting bmbr first is too much. A dozen fighters hitting at 2 could do some serious damage to a bmbr fleet. The interceptors might get slaughtered as well, but … Maybe hit bmbr first then alternate to escort? Or if the interceptors score more hits than the escorts the difference is applied to the bmbrs? Or just have it random?

3 bmbrs, 3 escorts against 4 interceptors. 1 hit for the bmbrs/escorts and 2 hits for the interceptors. 1 escort and 1 bmbr are killed. If the escort misses and the bmbr hits then both interceptor hits could be applied to bmbrs.

Hate to make things too complicated, but escorts would probably never get shot down, which doesn’t seem quite right.

Thanks Barney,
To get an answer, we need to compare the SBR House rule with G40 OOB SBR.
To get the numbers in your example:
1 StB + 1 Fg against 2 Fgs interceptors
1 StB + 1 Fg against 1 Fg interceptor
1 StB + 1 Fg against 1 Fg interceptor.

House rule (Bomber target first, A1 first strike as an AAA against up to 2 Fgs, whichever the lesser.)
Regular SBR                                                    / with +2 special HR bonus damage to IC when STB is killed by IC’s AAA
1 StB +1 Fg vs 2 Fgs, 1D6+2: 8.965 - 7.556 = +1.409 IPC damage/SBR  / +1.583 IPCs damage/SBR
1 StB +1 Fg vs 1 Fg, 1D6+2: +4.977 - 4.778 = +0.199 IPCs damage/SBR  / +0.440 IPC damage/SBR
1 StB +1 Fg vs 1 Fg, 1D6+2: +4.977 - 4.778 = +0.199 IPCs damage/SBR  / +0.440 IPC damage/SBR

SUM: +18.919 - 17.112 = +1.807 IPCs damage/SBR / +2.463 IPCs damage/SBR
With Oztea option: +19.575 -17.112 = +2.463 IPCs damage/SBR

1 StB +1 Fg vs 2 Fgs, G40 OOB: +7.775 - 5.33 = +2.445 IPCs damage/SBR
1 StB +1 Fg vs 1 Fg, G40 OOB: +7.639 - 3.667 = +3.972 IPCs damage/SBR
1 StB +1 Fg vs 1 Fg, G40 OOB: +7.639 - 3.667 = +3.972 IPCs damage/SBR
SUM: +23.053 - 12.664 = +10.389 IPCs damage/SBR

No intercept: 3 StBs = 7.749 IPCs damage/SBR
G40 OOB D6+2, 1 StB: +4.583 - 2 = +2.583 IPCs damage/SBR

1942.2 D6+2: +3.874 - 7.185 = -3.311 IPCs damage/SBR
1942.2 D6+2: +7.557 - 7.556 = +0.001 IPCs damage/StB
1942.2 D6+2: +7.557 - 7.556 = +0.001 IPCs damage/StB
SUM: +18.988 - 22.297 = -3.309 IPCs damage/StB

This HR with Oztea option is clearly positive and dangerous as well for both attacker and defender.
Under G40 OOB, you wouldn’t even risk interception, too bad odds: +10.389 IPCs instead of +7.749 IPCs damage/SBR for no intercept.

This HR SBR stay in positive for attacker and below the no intercept ceiling, making it a must to do so for defender:

Oztea option: +19.575 -17.112 = +2.463 IPCs damage/SBR
1D6+2 (avg 5.5 IPCs): +4.583 - 2 = +2.583 IPCs damage/SBR  /

+2.916 IPCs damage/SBR*3= +8.748 IPCs if no interception.

• The interceptors might get slaughtered as well, but …
Hate to make things too complicated, but escorts would probably never get shot down, which doesn’t seem quite right.

You are assuming that you will always have more Strategic bombers than defending Fgs.
It is not always the case, especially when you bring Fighters escort and also Tactical Bombers.

Also, you can minimize somehow the damage to Strategic bomber (doing D6+2, minimum 2 if hit by AAA) by using Tactical (doing only D6, zero if hit by AAA) as fodder.

In this balance SBR HR, bombers are the bait but, with preemptive strike @1 for bombers and Fighter escort attacking @2, it is no piece of cake for the defender.

The defender know that he can exchange Fg interceptors (10 IPCs, defense @4) for bombers (12 IPCs, attack @4) when casualties are even on a 1:1.
But the attacker still get the damage on IC, AB and NB, with surviving bombers.

What is the point to intercept when you can never hit bombers if there is too much escorting fighters?
Your are trading a 10 IPCs (defense @4) for a 10 IPCs (attack @3). This is not as interesting from defender’s POV.
There will be no interception at all, most of the time.

• The problem with AAs entire economic warfare model is, more often than not, the attacker runs the risk of losing more material in the bombing run than he causes in damage.

If you send in two bombers, and lose one to AA fire, you just lost 12 dollars and reduced your max damage from 16 to 8. Then, to add insult to injury you roll a 1 and do 3 damage.
SBR is a mess. I don’t think taking away the advantages for the attacker of bombers shooting in dogfight is a good idea, because it will just make SBR even worse of an option.

I have also for a while been dabbling in the concept of changing how AA works drastically that on rolls of ‘2’ it “scares away” an air unit. Meaning the unit simply doesn’t participate in combat but survives. A roll of ‘1’ would still be a kill shot. In all honestly this would eventually lead me to what my next idea was, which was another change. That facility AA can only “scare away” bombers, never kill them. and actual AAA gun pieces had to be at a factory to get kill shots during SBR and they fire after the dogfight step (if present). And even further (getting out of hand here) rolls of ‘1’ to hit during SBR count as a “hit” the bomber may allocate to a unit corresponding to their bombing target INSTEAD of damage.

So to summarize my wild and crazy SBR house rules.
Dogfight as normal. All air units fire at ‘1’ in one round.
AAA guns fire (if present) at Bombers/Tac Bombers only. Rolls of ‘1’ kill, rolls of ‘2’ “scare away” a bomber, forcing it to retreat.
Bombers select targets. Strategic bombers deal an automatic 2 damage to targets they select.
Facility AA fires. The weaker AA equipment can only deal “scare aways” on ‘1’ to bombers.
Bombers then roll for damage.
Rolls of ‘1’ count as bombing “hits”, all other rolls as pure damage.
An allocated hit can be:

• If a factory was targeted, a land unit, AAA, Tank, Infantry, Mech, Artillery

• If an Air Base was targeted, a Fighter, Bomber or Tactical Bomber

• If an Port was targeted, an adjacent Sub, Transport, Destroyer, Cruiser, Carrier or Battleship.

This addition is bonkers, but has been on my mind for a while. Take it for what its worth.

• The problem with AAs entire economic warfare model is, more often than not, the attacker runs the risk of losing more material in the bombing run than he causes in damage.

This addition is bonkers, but has been on my mind for a while. Take it for what its worth.

With your first idea, you cut a direct loss of 12 IPCs to 10 IPCs.

There must be some hazardous risk, it is part of the whole game.
Attacker can control a good part of it by choosing where and when making an attack or an SBR.

If you really feel that StBs doesn’t deliver enough damage, simply keep the mechanics and values I suggested and deal D6+3 damage with a 3 IPCs minimum, even if taken down by AA gun fire.

I selected D6+2, since it was an OOB value and in most configurations there is pretty positive odds.
Of course, they are no more as high as with G40 OOB SBR, but these odds (with attack and defense parity @1 between StBs and Fgs) were more deterrent to dogfight than incentive.

So, do you still feel that the OOB SBR at D6+2 wasn’t enough damaging for the risk involve with IC’s AA guns, from an attacker POV?

• From an attackers POV he can lose 12 IPCs or destroy 18 IPCs (if his bomber shoots down a dogfighter and rolls 6+2)

That’s a window of 30 ipcs that comes down to a few die rolls either saving you the game, or sending you up shit creek.

In all honesty, the bomber piece in AA should really be this

Bomber
8 IPCs
Attack 3 Defense 2 Move 6
Special Rule: Air Superiority - While a battle involves hostile enemy air units, bombers attack value is reduced to ‘2’ representing the interference from enemy aircraft.
