Raad-500 vs. Patriot PAC-3:

It is close to impossible for the PAC-3 ABM to intercept the Raad-500 TBM.

Beside higher burnout speed of 2,2km/s vs. 1,3km/s, the most important indicator of maintained speed are the nose angles:
Raad-500: 16° (smallest in TBM world)
PAC-3: 20°

1/3

The Pantsir SAM is one of the few system that are designed for speed of 1,3km/s at sea level (time critical cruise missile interception).
Its monolithic metal nosetip has an angle of ~19°

The impact speed of the Raad-500 is therefore certainly higher than 1,3km/s (>mach 4)

2/3

Beside being faster than the interceptor, the Raad-500 has a reservoir of delta ~1km/s KE, to perform random terminal f-pole maneuvering.
Instead of dissipating all excess KE to therm. heating, a portion can be utilized for course changes, to force the PAC-3 too bleed its KE

3/3

Reminder:
Due to the high dynamic pressures at sea level, thermal and mechanical stress becomes extremely high.
Only objects with highest l/d ratios and mechanical strength/thermal insulation can survive speeds of mach 3-4+.
--> no hypersonic ICBM RV impact at mach 7-20 possible.

FYI
Nosetip angles of other relevant systems:
Fateh-110 = 34°
Iskander = ~36°
Lora = 32°
Dezful = 25°
Zolfaghar = 20°
Hyunmo-2 = 25°

The higher the range + the smaller the angle and tip diameter --> the higher the allowed impact speed as per design without risk of disintegration
