The second series of tests was scheduled for 16 August 1921. The monitor fired a mix of shell types into "Baden" with her 15 in guns. This time, the shells did not perform as well against "Baden"s heavy armor; one of the AP shells failed to explode and two semi-AP shells appear to have broken up on impact. Six aerial bombs were also detonated on the ship, though they had been placed on board and were detonated remotely. The bombs did not perform as well as had been expected. Immediately following the second round of gunnery trials, "Baden" was scuttled. The ship sank in Hurd Deep in a depth of approximately 180 m (600 ft).
