Tainan Kokutai will take Frame IV (sorry Doc ~GRIN~).
Note that in a Series in which the Front was likely "supposed" to move to the West, the enemy only has two remaining fields from which twin-engine airplanes can be launched. If either one of them could be closed in Frame 4, they would only be able to launch (3) steps of twins in Frame 5. One is in the "north" and one is in the "south-east" of the map. Closing of either of these fields would, likely, limit Frame 5 action to ground attack fighters against our fields which are rather close to the Front.
