b29superfortress

Martin-Omaha manufactured "Silverplate" B-29 (B-29-35-MO, later modified to B-29-36-MO), USAAF Ser. 44-27296, named "Some Punkins" (ex- "Some Pumpkins"), built as part of the atomic bomb effort. Note the "Fat Man" mission markings, representing the number of times this aircraft bombed Japan with high-explosive bombs shaped like the plutonium-implosion device dropped by "Bockscar" (USAAF Ser. No. 44-27297) over Nagasaki on August 9, 1945. These high-explosive versions of the "Fat Man" nuclear device were known as "Pumpkin Bombs," hence this aircraft's name.

Since this also looks like a Korea photo, I believe this was 44-86376 in use by 19BG Stig
