Fido Acoustic Torpedo
 

This would be an interesting project for our MOD Wizards :)



The MK24 FIDO Record in Combat
The first confirmed FIDO sinking is believed, at this time, to have occurred 14 May 1943 when a PBY Catalina flying boat from US Navy VP-84 attacked and sank U-640 with a MK24 torpedo [more probable is that the first victim was the U-657 on May 17 - Editor]. Most US Navy composite squadrons flying from the ASW escort carriers operating in the Atlantic from mid 1943 on were equipped with FIDO as were the land based patrol squadrons. The torpedo was also supplied to the British and Canadian forces.

US Navy OEG Study No. 289, 12 August 1946 provides the following estimates of MK24 usage and results achieved:

Number of attacks in which Mk24s were launched 264
Total Number of Mk24 torpedoes launched - all targets 340
Number of MK24s launched against submarines 204
Number of Mk24 attacks on submarines by US aircraft 142
Number of submarines sunk by FIDO 31
Number of submarines damaged by FIDO 15
Number of MK24 attacks on subs by Allies (primarily British) 62
Number of submarines sunk by FIDO 6
Number of submarines damaged by FIDO 3
Total number of submarines sunk by FIDO (German & Japanese) 37*
Total number of submarines damaged 18
*Note: Includes five Japanese submarines sunk;
1 in the Atlantic
4 in the Pacific
A later submarine launched version of FIDO (MK27 Cutie) was developed for use against surface vessels and saw service use in the Pacific war beginning in the summer of 1944.

Torpedo MK24 FIDO continued in service with the US Navy until 1948.
