text: As the P-47 Thunderbolt worked up to operational status, it gained a nickname: the "Jug" (because its profile was similar to that of a common milk jug of the time).[Note 4] Two Fighter Groups already stationed in England began introducing the Jugs in January 1943: the Spitfire-flying 4th Fighter Group, a unit built around a core of experienced American pilots who had flown in the RAF Eagle Squadrons prior to the US entry in the war; and the 78th Fighter Group, formerly flying P-38 Lightnings.
