USS IOWA follows sister ship USS MISSOURI into Tokyo Bay, 29 Aug 1945

We continue to follow USS Iowa through 1945, moving toward the 75th commemoration of the signing of the instrument of surrender and the official end of World War II. Curator Dave Way is constantly updating and refining a timeline of the ship’s life. Here are its entries for 27-30 August 1945.



August 27 – An eventful day for Iowa.  0930 Commences entry into Sagami Wan, (an open bay 30 miles southwest of Tokyo), after Japanese emissaries, pilots, and interpreters have been transferred to Missouri from the IJN (Imperial Japanese Navy) destroyer Hatuzukura. As a unit of Task Group 30.1, Iowa is among the first ships of the fleet to enter Sagami Wan to commence the occupation of Japan.

It is three years since Iowa’s launch and the pit log reads 190,313 steaming miles. With battle victory flags flying, and all battle stations manned, she steams passed O’Shima, into Sagami Wan, and following the movements of Missouri, proceeds to the northern end of the bay to anchor off the shores of Japan’s Eno Shima.

At 1335 she is anchored in 36 fathoms of water. By sundown, many other ships of the Third Fleet have joined her, including HMS Duke of York (BB)USS South Dakota, Boston, Quincy, St. Paul, Chicago, West Virginia, Mississippi, Colorado and Idaho.

Reading about history is impactful, but there’s nothing like standing where it happened to make an indelible impression on one’s consciousness. Please help us preserve Battleship IOWA so she can continue to connect us to the enduring stories of our past that still shape our present and future.
