Thomas:
The Mark 27 had wooden strips mounted fore and aft, at 90 degrees on the battery compartment. They were just under 1" in height and this allowed the weapon to "swim out" of the tube; no impulse air was used.
About your real question.....
Maybe these countries entertained to possibility of using each other's torpedoes at some future date.
The German G7e was copied by the U.S. and that's how they built the Mark 18 battery-powered weapon. Westinghouse (with help from HUSL, Bell Labs and a rather reluctant Newport) redesigned the control mechanisms. gyro, and warhead. The motor, developing about 90 horsepower, duplicated in large extent the G7e. Westinghouse amazed even itself by its speed: in as a single month the engineers had a general design, and by May 2, 1942, BuOrd was confident enough to order 2000 units. On June 24, Westinghouse delivered the first test model to Newport. The rest arrived in July. Westinghouse's Sharon, PA plant manufactured the body, its plant in Springfield, MA made the control mechanisms, and the Electric Storage Battery Company (Exide) made the batteries.
Westinghouse copied the German T5 acoustic-homing torpedo when two of them came from the captured U-505, and it became the Mark 28, a 21" diameter heavyweight torpedo designed for submarine use, launched by compressed air.
The last Japanese combatant was sunk by a Mark 27 and a Mark 28 torpedo by the
USS TORSK (SS-423) one day after the war with Japan was over.
