Design and development
The Navion was originally designed at the end of World War II by North American Aviation as the NA-143 (but produced under the NA-145 designation). North American built 1,109 Navions in 1946–47, initially selling them at a below cost US$3,995, which later increased to $6,100, although the actual cost of construction was $9,000. These included 83 L-17As for the US Army and National Guard.[6]
Ryan Aeronautical Company acquired the design in the summer of 1947, launching production at its San Diego factory in 1948. Ryan built 1,240 Navions (powered by 205 hp (153 kW) Continental O-470 engines or 250 hp (190 kW) Lycoming O-435 engines), including 163 aircraft for the US armed forces, before production ended in 1951, with Ryan wanting to concentrate on defense production.
By the end of 1942, P-47Cs were sent to England for combat operations. The initial Thunderbolt flyers, 56th Fighter Group, were sent overseas to join the 8th Air Force. As the P-47 Thunderbolt worked up to operational status, it gained a nickname: "Jug" (because its profile was similar to that of a common milk jug of the time).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.

The P-47 proved to be a formidable fighter-bomber due to its good armament, heavy bomb load, and ability to survive enemy fire. The P-47's survivability was due in part to its radial piston engine, which unlike comparable liquid-cooled engines, had a high tolerance for damage.
Other positive attributes included the P-47's ruggedness; its radial piston engine had a high tolerance for damage compared to liquid-cooled engines,
