The Jug was a type of airplane, the P-47 Thunderbolt, WWII's heaviest single-seat fighter plane. The British or someone had informally named it the "Juggernaught", which the pilots then shortened to just "Jug". These planes served with great distinction from '43 through '45, and caused severe headaches to the Axis. It's not exactly a beautiful looking plane, but it is impressive looking. Very powerful and heavily armed. Comes in earlier fastback version, and later bubble canopy. Many of these Jugs served after the war in various air forces of smaller countries, specially in South America.
