Thnaks for the feedback has anyone tried these out yet.  Unfortunately i havent been able to get a group together since i wrote these.

Advanced Island Airbase Rules
For AAP40
Version 1.0
Created By Jeff Zieleniuk 03/09/2010

Here are some additional Island Airbase rules, to simulate a more realistic airbase structure, and air war scenario. During WW2 capturing islands was important strategy to move closer to objectives, many of these islands were under developed, and not suitable for landing aircraft until improvements were made. Capturing these island to extend the ability to position aircraft was imperative, as this reduces the need for a huge carrier fleet, and gave both sides the ability to more effectively protect shipping lanes, and launch sorties without putting carriers in harm’s way of enemy fleets.
Airbases still provide all the normal functions as per the Base rules found in the rule book, these are in addition to the existing rules. Please feel free to use only part of these to fit your taste of game play.

1. Airbases are required to land on an island. Continental Territories; N. America, Asia, Australia, and Japan ignore these rules. In effect you can land planes on any friendly controlled territory that is on a continent as per normal rules.  If you wish to land aircraft on an Island it must have a friendly airbase for you to be able to land on. During Setup if you have aircraft stationed on an island (example Formosa) simply place an airbase on that island. Remember continental territories such as Manchuria are exempt from this rule.
2. Basing Limits.  Island Airbases have a limited capacity to hold planes, at the start of the game island airbases can base 9 aircraft (Exception: Continental Territories; N. America, Asia, Australia, and Japan ignore these rules.)
3. Upgrading an Airbase. During your Purchase Phase you can upgrade an existing Island airbase facility, for Every 5 IPC you spend on Upgrade you can base an Additional 3 planes. Use some sort of marking mechanism to show the facility has been upgraded. Each upgrade bought will also increase the amount of damage the Island airbase is capable of taking. For every upgrade applied increase the damage capacity by 1. ( Example, In normal rules an airbase take 3 hits of damage it is inoperative until repaired, so Say the airbase on the Philippines is upgrade one time it can now house 12 aircraft, and takes 4 points of damage to make it inoperative).
4. Island Airbase Damage.  Island Airbases may be bombed during an SBR to make them inoperative, and negate the effect it confers to units and the map. For every one point of damage applied the base losses the capability to land, or launch 3 aircraft until repaired, this includes scramble ability and SBR Defense. This does not affecting basing rules, aircraft in excess of the aircraft limit are considered grounded do to runway cratering, damage to facilities, and decreased logistical support.
   • If planes are launched in defense of an SBR against an Island Airbase, and enough damage is done to the airbase to restrict some or all of the defending planes from landing, they are allowed to immediately take their full movement to either find another island airbase , continental territory, or aircraft carrier to land on, if none are in range the plane is lost.
   • If an Island airbase is made inoperative, it cannot launch or land aircraft, it cannot be used to scramble, SBR Defense, or confer movement bonus. Also in addition to this, if an island airbase is made inoperative the planes on it are effectively grounded, they cannot be launched. (Example Bombers can’t be used in SBR defense, they could become stuck on the airbase, or if you decided to not use fighter aircraft in defense of an SBR.) If an island airbase is reduced to 0 points, any further bombing runs made against the facility, will instead destroy grounded aircraft. This is accomplished by rolling one dice for every bomber than makes a run against an inoperative facility, for every roll that comes up a 1 destroy one grounded aircraft, all other rolls are considered misses.

Please feel free to use this in your game; also please let me know if you have any other ideas that could be merged into this. Above all please comment.
PM me and i can send this to you in .doc format.

@Zieleniuk:

Well i see that point but if it was used in tandem with aircraft carrier you could negate alot of those area until you took over those areas. I do see you point thought with the restirction especailly on the japanse side if you are trying to use alot of planes in hitting the US. The few game si have play the middle pacific island are usually not used and are ignored.  I was hoping that this mechanic would make those territories a bit more vital.

I think it is an interesting idea, although you’d have to reduce the cost of airbases to 10 or even lower. That way it would incentive players to build airbases on newly conquered territories and change the dynamics a bit.
But I definately don’t think it would give much of an incentive to go more for the central pacific. The IPCs and the national objectives are near all in the South Pacific/DEI islands, with the exception of the Iwo Jima/Okinawa NO. Perhaps you’d have to change the NOs a bit to bring more fight to the Central Pacific because just changing the airbase rules would not be enough.

Thanks for the input you are probably right about the NO thing maybe i will tinker with that some also :-D

@Hobbes:

Planes would be heavily restricted on their movement, since they would be limited to moving between airbases. Some areas of the map might be completely off limits to fighters/tac bombers unless bases are build there, limiting options for Japan during the 1st rounds.

Well i see that point but if it was used in tandem with aircraft carrier you could negate alot of those area until you took over those areas. I do see you point thought with the restirction especailly on the japanse side if you are trying to use alot of planes in hitting the US.

No it would still give out all the other bonuses, jsut add these to them. So you would still get the extra movement, and the scramble ability.

I was also thinking about as far as basing limits, a base airbase could base 8 aircraft, and that you could upgrade them as a buy in during the purcahse round. So for example you could buy an upgarde for X ipc that would  y more planes to land there.  You could mark it with a chip or something to show that is was upgraded. I would say the starting home base territoies for aircraft West US Tokyo etc, have an unlimited basing number or something extremely high 20 - 30. This way it could still effectively be bombed, to limit capacity, but the chances of it being completely knocked out, would be little to none.

I have had my copy of AAP40 for a week now, and I am a long time player.  I really like some of the new mechanics in the game, but was disappointed that Airbase aren’t required to launch or land aircraft.  Has anyone else started thinking about this?  It seems to me it would make those island bases alot more valuable, since they are worth nothing IPC wise. The only issue that i can forsee with this is aricraft based in China at the beginning of the game.

Here are my ideas, in addition to the base rules for Airbases, please comment as you see fit.

1. All aircraft (besides carried based) are required to land at a friendly airbase at the end of the non combat movement phase.
2. Basing Limits, still trying to decide on a number, but have it go down with each hit applied to the airfield much like Unit placement on Industry.
3. If the base is inoperative no planes may take off or land at the base until repaired.

Obviously this would further complicate the game, but i personally dont mind the complication to maybe add a bit of value to the game.
