26 March 1946:
NAGATO's hull proves unseaworthy because damage resulting from near misses received during the air raid on 18 July was never repaired by the Japanese, nor the Americans. Her pumps cannot keep up with the intake of seawater. NAGATO ships about 150 tons of seawater in the forward compartments. The stern compartments have to be counter-flooded with 260 tons of water to maintain the balance.

28 March 1946:
The SAKAWA breaks down and goes dead in the water. NAGATO sets a tow-line to SAKAWA, but then NAGATO blows out a boiler, and runs out of fuel. Both ships are stopped in bad weather. NAGATO's crew radioes to Eniwetok for help.

NAGATO is joined by the American target battleships ARKANSAS (BB-33), NEW YORK (BB-34), NEVADA (BB-36), PENNSYLVANIA (BB-38) and other ships. NAGATO is moored 400 yards to the starboard of NEVADA, the target ship for the test. The bomb misses NEVADA. NAGATO, 1,640 yards from Ground Zero, sustains only moderate damage - wrinkled superstructure plating, non-watertight doors blown off and overall paint scorching, but SAKAWA capsizes and sinks the next day.

16 July 1946:
Salvage vessel USS CURRENT (ARS-22) moors alongside NAGATO for two hours and forty-seven minutes to hoist NAGATO's anchor aboard CURRENT.

24 July 1946:
At Bikini. The underwater atomic bomb detonation test "Baker", organized by the US Navy, destroys NAGATO. NEW YORK, NEVADA and PENNSYLVANIA survive both bomb tests.

After the explosion, NAGATO is reboarded. No. 7 boiler is reactivated for the next 36 hours.

29 July 1946:
At Bikini. NAGATO capsizes and sinks at night. She comes to rest upside down in about 160 feet of water. Her pagoda superstructure is broken away but its stump still supports the hull.

Authors Notes:
[1] According to some sources, the explosion took place in Sagami Bay; however, numerous Japanese sources state it happened at Saeki.

[2] The Japanese continue to develop the apparatus which is later designated the Type 22 surface search radar.

[3] Mt. Niitaka, located in Formosa (now Taiwan), is then the highest point in the Japanese Empire.
