U. S. Submarine At Full Speed Ahead
| Series 11|
A submarine at full speed makes 18 knots an hour on the surface - about 12 knots when submerged. The craft shown here has accommodations for the crew - 22 men and two officers. Gone are the days when our sub-sea craft had to stay close to the side of her large sister ship to provide the crew with proper living quarters. If only J. P. Holland, the American who invented and built the first successful submarine could be here to see his dreams come true in this deadly little craft of today!
