and our 3.5in and german (nerfed) rockets still meet need with more lb. and boom power. so really why
The 3.5 had a 20lb warhead, but it only had around 1/2 mile range ... a trade off... The German 28cm rocket was potent, but had a max range of a little over a mile... and it weighted close to 200 lbs... The warhead was almost 100 lbs, but it was low yeild, not torpex and NOT Armor Piercing ... and there was an incendeary version that had 13 Gal of High Grade Fuel in it. Everyone had more potent rockets than the B-13, But it was probably the MOST feared weapon in the russian arsenal ... and was very easy to handle and simple to use. An area pulverized by a Katyusha Barrage looked something like the darkside of the moon.
