Awarded from 1941. The U-Boot-Kriegsabzeichen mit Brillanten look similar like the usual U-Bootskriegsabzeichen, but is was made from gilding silver with 9 small diamonds. The badge was presented roughly 30 times, it was usually awarded when a commander was decorated with the Oak Leaves. Admiral Dönitz wore a special piece of this decoration.
For the following commanders I have the certain award dates:
| 15 Jul 1941 | Kptlt. Herbert Schultze | U-48 |
| 18 Jul 1941 | Kptlt. Engelbert Endraß | U-46 |
| 31 Dec 1941 | Kptlt. Reinhard Suhren | U-564 |
| 11 Apr 1942 | Kptlt. Erich Topp | U-552 |
