Encyclopedia > Type 91 torpedo

The Type 91 was a 17.7 inch diameter torpedo of the Imperial Japanese Navy. Designed primarily to be launched from an aircraft, it was also used by midget submarines.


Seven models were produced in all, with warheads ranging from 331lb (model 1) to 926lb (model 7) and ranges from 1500 to 2000m at 44 knots. The later, heavier models had decreased range, but this was not an operational problem as close launching was necessary for accuracy in any case. Note there were no models 5 or 6, but three different versions of the model 3 differing mainly in their maximum launch speeds.

The first torpedoes driven at specific targets were spar torpedoes; the explosive device was on the end of a spar up to 40 feet (12 m) long projecting forward underwater from the bow of the attacking vessel.
A derivative of the compressed-air torpedo was the steam torpedo.
In the case of deck or tube launched torpedoes, the diameter of the torpedo is obviously a key factor in determining the suitability of a particular torpedo to a tube or launcher, similar to the caliber of the gun.
Type 93 torpedo - Wikipedia, the free encyclopedia (739 words)
The Type 93 was a 610 mm (24 inch) diameter torpedo of the Imperial Japanese Navy.
A 17.7 inch (450 mm) version designated the type 97 torpedo was later developed for use by midget submarines, but was not a success and was replaced operationally by the type 91 torpedo.
In surface battles, by the time the deck-mounted torpedo tubes were reloaded ready to launch a second wave of torpedoes, allied ships were close enough to able to use their torpedoes as well and the advantage of reloads was reduced.
