I wonder if RR633 is a reference to Rolls Royce - ?

A quick search revealed the Rolls Royce (Armstrong-Siddeley) Viper Mk. 633 built under licence by Turbomecanica and Orao for the IAR-93 Vultur, Soko J-22 Orao, IAR-99 Soim and Soko G-4 Super Galeb.

But I'm not an engineer, and barely even a pilot, let alone a military one, so I'm probably wrong.
