Designed in 1938 as a medium range, single-seat bomber the IL-2 became the most produced aircraft of World War II. The initial single seat version entered production in early 1941 and remained in production until the summer of 1942 when it was replaced on the assembly line by the IL-2M two-seat version. The IL-2M was a stopgap design rushed into production to address the most serious flaw in the aircraft, the lack of a rear firing gun. This version of the Shturmovik was replaced by the Il-2 Type 3 in late 1943 which further modified the design to improve performance and stability. The modifications included a 15-degree sweep on the leading edge of the wing which improved the plane's stability, and a more powerful engine. The shortage of aircraft aluminum that plagued the Soviet Union for most of the war resulted in some of the Shturmovik's most interesting features. Until late in 1944 the wings and rear fuselage of the plane were built of wood, with only the heavily armored center section and nose of the aircraft being of metal construction. Eventually, over 36,000 Shturmoviks of all models were produced, making it the most produced aircraft of the war.

Consider that there are only 19 of these aircraft that survive today. And according to Wikipedia only two are airworthy. The rest are on display or in storage, and only two of those are in the U.S. This is pretty amazing since (per Wikipedia) "...in combination with its successor, the Ilyushin Il-10, a total of 42,330 were built, making it the single most produced military aircraft design in aviation history..."

Here is more information from "Ilyushin Il-2 Shturmovik," by John Bezosky, in "Skywriting," the Summer/Fall 2020, edition of The Arizona Aerospace Foundation Magazine:

"This Ilyushin Il-2 is a two-seat, straight wood wing and fuselage Shturmovik. It left Factory #1 in Kuibyshev, Russia in February, 1943."
...
"However, on January 28, 1944, while attacking German troops retreating from Leningrad, "5612" was shot down by ground fire that damaged the oil cooler for the engine. Pilot Junior Lieutenant Mark I. Andaralov and Gunner Sgt. Leonid Grishan were forced to find a suitable place to ditch the damaged Il-2. Both survived the wheels up landing of "5612" on a frozen lake approximately 90 miles south of Leningrad and were able to return to their unit. The airplane remained abandoned on the ice and in the spring thaw, "5612" sunk into the cold, fresh water to rest on the black peat of Lake Bebro."

It was finally recovered in March of 1992, and PASM was contacted in 2002, when the aircraft was offered as a donation. It was mostly in storage until May, 2016, when restoration began. In March of 2020, it was put on display.
