FLAG INFERIOR
1939PRIOR TO THE NAMING OF SUBMARINES, THE NORMAL PROCEDURE WAS THAT THE SUBMARINE NUMBER WAS REVERSED, TO FORM THE PENNANT NUMBER. THESE NUMBERS WERE USUALLY FLAG INFERIOR NUMBERS. FOR EXAMPLE SUBMARINE H49 WORE THE PENNANT NUMBER 49H. UNTIL THE SECOND WORLD WAR, IT WAS USUAL FOR SUBMARINES TO HAVE ONLY A PENNANT NUMBER AND NO NAME; WINSTON CHURCHILL DIRECTED THAT ALL SUBMARINES BE NAMED.
