Angry thread about M270 MLRS and M142 HIMARS 🧵
and a bit about BM-27 Uragan and BM-30 Smerch too.
Angry, because every M270 and M142 thread I have seen on twitter so far is FULL OF MIND BOGGLING ERRORS... because all of them (!) use as source of their "knowledge" the

Let's dive in. First: M270 and M142 are technologically decades ahead of their Soviet-era counterparts: BM-27 Uragan and BM-30 Smerch. See the red arrows I painted? Yes, those are optical sights...

Uragan and Smerch have to be sighted optically... and in the case of the Uragan soldiers have to adjust elevation and deflection by turning wheels.
Even Uragan's two outriggers have to be lowered and emplaced by muscle power.

Optical sights means that it takes the 10-12 minutes to measure and prepare a launch sites and sight a launchers.
Firing dumb rockets with optical sight also means that the Uragan and Smerch's accuracy is atrocious... i.e. when a Smerch fires its 12 rockets,

then the circular error probable (CEP) is 170 meter. This means only 50% of rockets fall within a 170 meter radius of the actual target... the other 50% will come down even further away than 170 meter from the target.
Meanwhile US GLMRS missiles have a CEP of 5 meters.

This is the reason russian forces fire mostly rockets with cluster munitions. They know they can't hit a target, so they saturate the area around a target with cluster munitions, hoping that at least something will hit...

And reloading the Uragan and Smerch is a time-consuming drag... It takes 20 minutes to reload a Uragan and it takes 5x russians 40 minutes to load 12x rusty rockets into a Smerch.

Ukraine also uses Uragan and Smerch, but russia has bombed Ukraine's rocket factories and as no allied nation produces Uragan or Smerch rockets, Ukraine desperately needs M270 and/or M142 launchers with their more accurate missiles.

Besides the accuracy of their missiles, what else makes the M270 and M142 so much better?
For starters: the speed of reloading. Both use rocket pods pre-loaded at the factory with either six GMLRS missiles of the same type or one ATACMS missile. Trucks bring the pods to

predesignated ammo supply points, where M270/M142 exchange their used pods for new ones in 5 minutes thanks to their built in cranes.
Meanwhile the truck is already on its way to get more pods.
And if you're in a hurry - the M270 can reload its pods simultaneously.ously.

Well, with a top-secret tool called "keyboard". This must sound like magic to russian soldiers with their sights and collimators.

The M26 series were unguided, cluster munitions rockets. The US Army acquired 506,718 and used around 17,000.
The M26 and the extended range M26A2 were carrying M77 submunitions, which had a fail rate of more than 5%. The M26A1 was an extended range version of the M26

The M30 series consists of two GPS-guided missiles (GMLRS) with different warheads:
• M30 - with M101 cluster munitions (2% duds)
• M30A1 - Alternative Warhead, with 160,000+ Tungsten balls - it is like a giant shotgun

but because of the 2% fail rate of the M101 cluster munitions the army stopped buying the M30 in 2009 and focused on developing the M30A1.
