Re: Rocket artillery
122mm 9M22U HE-Frag warhead weight: 18.4 kg
122mm 9M28F HE-Frag warhead weight: 21 kg
Now from what I'm gathering on the Italian Wiki entry for the FIROS-30 (not exactly the most reliable source I'm aware), the warhead weight of the FIROS-30 HEI warhead is 26.5 kg
This is substantially larger than the older 9M22U and still significantly larger than the newer 9M28F.
Just because two rockets share the same caliber and origins doesn't mean they share the same warhead.
