The Battle of the Pips refers to an incident that occurred on 27 July 1943, as part of the Aleutian campaign of World War II. In preparation for the attack on the island of Kiska planned for that coming August, the U.S. Navy formed Task Group 16.22 (TG 16.22) under command of Rear Admiral Griffin, which was then centered on the battleships Mississippi and Idaho. On 27 July, west of Kiska, TG 16.22 began to pick up a series of unknown radar contacts. The order was given to open fire, and 518 shells from both battleships were expended, but there were no hits.
