Editing Gato-class submarine (section)

====Mine armament====
Like the previous Tambor/Gar classes, the Gato class could substitute mines in place of torpedoes. For the Mk 10 and Mk 12 type mines used in World War II, each torpedo could be replaced by as many as two mines, giving the submarine a true maximum capacity of 48 mines. However, doctrine was to retain at least four torpedoes on mine laying missions, which further limits the capacity to 40 mines, and this is often stated as the maximum in various publications. In practice during the war, submarines went out with at least 8 torpedoes, and the largest minefields laid were 32 mines. Post-war, the Mk 49 mine replaced the Mk 12, while the larger Mk 27 mine (in actuality an acoustic-homing torpedo) was also carried which only allowed one mine replacing one torpedo.<ref>[https://maritime.org/doc/mines-usn/index.php ORD696 Operational Characteristics of U.S. Naval Mines]</ref>
