One of the features of the Panther KF51 was the 130mm gun. It is noted that the tank concentrated its firepower for long-range strikes in battles with several targets. The Future Gun System, developed by Rheinmetall, allows you to achieve a 50% greater range (than 120 mm).
In addition, optional HERO 120 loitering ammunition expands the Panther's non-line-of-sight strike capabilities. The concern also claims that the combat weight of only 59 tons provides greater mobility.
