Edited sentence: By August 1943, Panthers were being built only with a homogeneous steel glacis plate.The Panther front hull had 80mm of armor sloped back at 55 degrees from the vertical, welded but also interlocked for strength.The combination of a steep slope and thick armor meant that few Allied or Soviet weapons could penetrate it.The initial production Panthers had a face-hardened glacis plate (the main front hull armor piece), but as  armor-piercing capped rounds become the standard in all armies (thus defeating the benefits of face-hardening, which caused uncapped rounds to shatter), this requirement was deleted on March 30, 1943
