U-class boats supplied the numbers needed for the Mediterranean submarine campaign. Too few of them forced the Royal Navy to bring in larger S- and T-class boats. In this assessment, those larger boats were poorly suited to the confined Mediterranean, with the T class particularly oversized. More U-class boats would have allowed the larger submarines to be used elsewhere.
