Authors' Note:
[1] In 1945, the U. S. Army Air Force launched a five-phased campaign known as “Operation Starvation” to mine Japan’s home waters. The USAAF used 80 to 100 B-29 “Super Fortress” heavy bombers of the 21st Bomber Command based at Tinian in the Marianas. The B-29s could carry seven 2,000 lb. or twelve 1,000 lb. mines.

Beginning on 27 March 1945 and continuing until 5 August 1945, the B-29s flew 1,529 nighttime radar sorties and laid 4,900 magnetic, 3,500 acoustic, 2,900 pressure and 700 low-frequency mines for a total of more than 12,000 mines laid in Japanese waters. These mines sank 294 ships, damaged 137 beyond repair and damaged another 239 that could be repaired. The total was 1, 250,000 tons sunk or damaged or about 75 percent of Japanese shipping available in March 1945. Only 15 B-29s were lost during the mining campaign.

Postwar, removal of these mines posed a major challenge for the Allied Occupation Forces. They pressed 269 Japanese ships of various types into mine sweeping service to augment their own efforts.
