A second B29 named for the 30th Naval Construction Regiment painted by Bill Valentine but this one displays a cartoon GI on a bulldozer on the regimental motif. It was initially assigned to 411st Bomb Group in March 1945 and may have carried the name 'Island Girl'. Later transferred to 505th it was embellished with the title 'Big Mike' and given the regimental motif by Valentine, possibly after the was had ended. On 29 October 45, the Superfort returned to the USA and placed into storage until salvaged on 24 April 1951.

Unfortunately, the identity of this Superfort has yet to be established.
