One of the "Sunsetter" groups of P-51s of the 7th Fighter Command, the 506th FG was the last to arrive on Iwo Jima. The group at first flew ground support missions against other islands in the Bonin Islands. They later flew escort for B-29 raids and fighter sweeps against the Japanese home islands. I made separate packs for each squadron mainly because of the number of skins. I was blessed with help from the 506th website's webmaster, Robert Grant, in compiling enough information to make a good number of skins.
