Originally designed as a single seat dive bomber, too late to see service in WWII, this huge beast carried out multiple roles in Korea and Vietnam. Close air support, search and rescue, hospital transport, nuclear certified (believe it or not) and many more roles, it could carry 12.000 pounds of ordinance. It was well armored around the cockpit, able to withstand large amounts of battle damage from small arms fire and some AA, it (and the P-47 Jugg) was the predecessor to the A-10 Thunderbolt. It was easy to fly and could loiter all day long.
