Operation Tan No. 2 (,
Dainiji Tan Sakusen) was a long-range
Kamikaze mission directed at the main
Allied naval fleet anchorage at
Ulithi atoll in the western Pacific on March 11, 1945 during the
Pacific campaign of
World War II. The Japanese hoped to take the U.S. Pacific fleet by surprise and sink or damage a significant number of the fleet's
aircraft carriers or other large ships.
