                {
                    if ((actor as AiGroundActor).Player(i) != null)
                    {
                        actorDestroyable = false;
                        break;
                    }
                }
        }

        return actorDestroyable;
    }

}

added the Action Names for Fighter spawn to the Queue.
First is Bomber, second is fighter.

then i modify the

 if (enemyAircraftsInGame.Count <= MinNumberEnemyPlanesAlive)
        {
            string actionName = ActionQueue.Dequeue();
            ActionQueue.Enqueue(actionName);

            AiAction action = GamePlay.gpGetAction(actionName);
            if (action != null) action.Do();


            actionName = ActionQueue.Dequeue();
            ActionQueue.Enqueue(actionName);

            action = GamePlay.gpGetAction(actionName);
            if (action != null) action.Do();


        }

so it reads the action two times from the Queue. First creates the bombers the second the fighters or vice versa, depens on the actions you created.
