All the Harrier just recently got a buff in this major update. So the stat card should be updated to match this.
For the Harrier 1
Max Speed at 0 meter should be 620 knots (5 pylons + guns)
Rate of climb: 126 m/s
Turn time: 26 seconds
Max altitude: 15,544
Takeoff run: 0 lol
The current stat card makes out like it’s still the brick it was wrongly put in game as.
