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
30 March 1946:
Two USN tugboats arrive from Eniwetok. NAGATO is taken in
tow by USS CLAMP (ARS-33). Without power or pumps NAGATO takes on more water and
a seven degree list to port. NAGATO is towed at 1 knot.
4 April 1946:
Arrives at Eniwetok where the flooded compartments are
pumped out. Undergoes repairs to hull and machinery.
Steams at 13 knots for 200 miles to Bikini Atoll.
1 July 1946: Operation Crossroads:16 July
At Bikini. NAGATO and SAKAWA are target
ships in the atomic bomb air burst detonation test "Able"organized by the USAAF
. 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.
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:After the explosion, NAGATO is
reboarded. No. 7 boiler is reactivated for the next 36 hours.
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.
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.
 According to some sources, the explosion took place in
Sagami Bay; however, numerous Japanese sources state it happened at Saeki.
 The Japanese continue to develop the apparatus which is later designated the Type 22 surface search radar.
 Mt. Niitaka, located in Formosa (now Taiwan), is then the highest
point in the Japanese Empire.
