Steelhead and Tinosa was what sparked my interest in US subs and torpedo devlopment. after i read an account of both ships firing a total of 20 torps between them into the tanker Kazahaya(sp?) before it sank. can say that it was in spite of ,rather then because of, the quality of the weapons with which the US submarines were armed that they achieved their great success. i got respect for submariners, but could never be one.
