Germany's Rheinmetall has announced their newest creation: KF51 Main Battle Tank, dubbed "Panther." I don't know if this is just a design prototype or if they're preparing serial production and when, but two things come to mind immediately:
1. Ukraine is going to demand some; and
2. The naming has to be deliberate.
You see, the original Panther was called Panzerkampfwagen V (or Sd.Kfz. 171), designed by Nazi Germany to counter the T-34 on the Eastern front from 1943 onward. Spoiler: It didn't work.
For reasons unbeknownst to me, postwar Germany was allowed to continue naming their armor after cats (Lynx, Gepard, Puma, Leopard series) and even reusing "Marder" (used in WW2 for tank destroyers produced by converting captured vehicles) for IFVs. But they've steered away from the "big cats" of WW2 — Tiger and Panther — for obvious reasons... until now.
