I-25 Otsu Gata

Historical information

I-25 was a B1-Type (I-15 Class) submarine of the Imperial Japanese Navy that served in World War II, took part in the Attack on Pearl Harbor, and carried out the only aerial bombing on the continental United States during wartime; during the so-called Lookout Air Raid; and the Bombardment of Fort Stevens, both attacks occurring in the state of Oregon.

I-25, of 2,369 tonnes (2,600 tons), was 108 m (354 ft) long, with a range of 25,928 km (14,000 nmi; 16,111 mi), a maximum surface speed of 43.5 km/h (23.5 kn; 27.0 mph) and a maximum submerged speed of 15 km/h (8 kn; 9 mph). She carried a two-seater Yokosuka E14Y reconnaissance floatplane, known to the Allies as "Glen". It was disassembled and stowed in a hangar in front of the conning tower.

I-25 was sunk less than a year later by the destroyer USS Ellet off the New Hebrides islands on 3 September 1943.
