The Panther tank came as a shock to US forces in the days after the Normandy invasion. Not that the Panther was unheard-of before D-Day. But somehow, the substantial information on the characteristics of the new German tank that were available to the US Army had not been correctly interpreted, and so its combat capabilities and its impact on operations had not been anticipated

Because the Germans didn't use any at Kursk, and the Allies had no reports from the Russians as to the effectiveness of it, or what it would take to kill one.

The Soviets had captured or recovered several Panthers after the great armored battles of Kursk and their subsequent great advances across the Ukraine in the summer of 1943.”

Lauchert's Panzer Brigade at Kursk was equipped with early versions of the Panther.
