I'm pretty sure any military aircraft are able to go slower than 200 kts once configured (dirty). How else do they land? For sure not at 200+ kts?
If you meant to say clean speed, then that applies to any heavy aircraft - min clean speed on any widebody at landing weight is well above 200 kts.
Perhaps you were thinking of hold speeds, where there may be exemptions to allow heavier a/c to hold at higher speeds to prevent having to do so with slats/flaps extended...?
