M-1 743k All the news that's fit to misprint, #1.
UNITED STATES TESTS FIRST OF BIG NEW SEA-GOING SUBMARINES
The M-1 (SS-47) is shown on her trial trip off Provincetown, Mass., on 6 July. She is 230 1/2 feet long, with 21 1/2-foot beam. Her radius of action is 2,000 miles.
She is not as large as the German submarine Deutschland, now at Baltimore, whoso length is 315 feet, with a 30 foot beam.
It is actually an EB design L-class boat. The paper that originally published the photo misidentified it. The caption is wrong.
