While not as pretty, the A10 Warthog probably fills that role very nicely.
The A-10 went through my mind, of course. However, the WWII equivalent of the A-10 was the Republic P47 Thunderbolt, often called “The Jug”. Like the A-10, the Jug was a flying tank that could drop ordinance, blast the crap out of a target with its 8 airborne version M-2s and take a holy hell beating.
However, the P-51 was pure elegance, taken from idea to flyable prototype in 120 days! Pure beauty, inspiration and a viper’s bite rolled into one machine.
