Ten 21 inch torpedo tubes, six fore and four aft, plus its 3 inch deck gun and two anti aircraft machine guns make it a craft to be feared by the enemy. Displacement is 1,450 tons on the surface, length almost 300 feet, and speed almost 22 knots. Such submarines often have a range of 15,000 miles.||Text courtesy of CARD-O chewing gum.

|203k||These U.S. Navy diagrams show how the Torpedo Data Computer (TDC) was to have been used. At left is the pair of own and target dials, showing the target and the submarine. The officer making the approach had to work out the course needed to obtain a given track angle. If the two dials were mentally superimposed (as at center), they showed the angle between the courses of the submarine and the target.
For a stern shot, the necessary course angle appeared opposite the angle on the bow corresponding to the desired track angle. For a bow shot, the necessary course angle was read off 180 degrees from the angle on the bow. True (as well as relative) bearings were shown on these dials because they corresponded to directions actually steered.
Arrows on the TDC indicated torpedo course and gyro angle, as shown at right (solid arrow for bow tubes, broken arrow for stern tubes). The arrows on the target dial indicated present track angle, the angle at which the torpedo would hit if it were fired at any given moment (i.e., how good a shot was likely to be).
Present track angle for a straight shot could be read off the dials by transposing the number on the outer ring opposite the submarine's disengaged axis to the target outer ring, then reading the corresponding inner number. In this example, submarine & target are on converging courses.
The Tambor (SS-198-203 class) was the first designed specifically to accommodate the TDC.
