Bockscar and Enola Gay were used for other missions... here we are with the rash statements again.
By regular bombs, I'm sure you will defualt to pointy things with a tail, you were meaning high explosive not atom..
"Bockscar was used in several training and practice missions from Tinian, and four combat missions in which it dropped pumpkin bombs on industrial targets in Japan. Bocks crew bombed Niihama and Musashino, and 1st Lt. Don Albury and crew C-15 bombed Toyama."
"The B-29 was delivered to the 393rd Bomb Squadron at Wendover Field, Utah, where aircrews of were engaged in intensive training under a cloak of secrecy. In June, aircraft and crew flew to Tinian Island in the Marianas. From there, "Bockscar," named for its pilot (Bock), flew five bombing missions. On four of these, a 10,000 pound bomb loaded with high explosives was dropped. Nicknamed "pumpkin" bombs because of their shape and orange color, these were the same size and shape as the actual atomic bomb dropped at Nagasaki"
"The Enola Gay arrived on Tinian on 6 July 1945. Prior to flying the first atomic combat mission the Enola Gay flew eight practice missions from Tinian, then two conventional bombing missions over Japan using the 6300 pound "pumpkin" high explosive bomb, designed to simulate the characteristics of the Fat Man bomb. The Enola Gay bombed Kobe on 24 July and Koriyama on 26 July."
