After whatching the movie Midway. How about making an auto pby that hunts for enemy cv's and planes. It could display the enemy cv, for example, on the map when in visual proximity. It may be shot down by enemy and able to respawn after a time delay similiar to buildings.
P.S. Would like a P-61C for x-mas.
P-61 Armament:
4× 20 mm Hispano M2 cannon in ventral fuselage, 200 rounds per gun
4× 0.50 cal (12.7 mm) Browning M2 machine guns in upper turret, 560 rounds per gun
For ground attack, two bombs of up to 1,600 lb (726 kg) each could be carried along with six 5 inch (127 mm) HVAR unguided rockets under the wings. Some aircraft could also carry one 1,000 lb (454 kg) bomb under the fuselage.
