pbear: You must've mistyped. Try 380mm. Here's a partial quote from achtungpanzer.com
quote:
The Sturmtiger was armed with a short-barreled 38cm Raketenwerfer 61 L/5.4, breech-loading rocket launcher/mortar. The RW 61 launcher fired short-range (4,600 to 6,000 meters, or 2,850 to 3,720 yards) high-explosive rocket-propelled projectiles. The launcher was fitted with a PaK Zielfernrohr 3 x 8 telescopic sight. Each projec-tile was almost 1.5m (five feet) long and weighed 345 to 351kg (759 to 772 pounds). Two types of ammunition were available-high-explosive Raketen Sprenggranate 4581 (with a 125kg, or 275 pound, explosive charge) and shaped-charge Raketen Hohladungsgranate 4582 for use against fortifications. The shaped-charge round could penetrate up 2.5m (8 feet) of reinforced concrete. The Sturmtiger main arma-ment was originally developed by Rheinmetall-Borsig in Dusseldorf from an anti-submarine depth charge launcher developed for the Kriegsmarine. The main armament could be traversed by hand 10 degrees to the left and right and elevated from 0 to a maximum of 85 degrees. The launcher produced a recoil force of 30 to 40 tons. Perhaps the most unique feature of the launcher was the way rocket exhaust gasses were vented. These gasses could not be allowed to enter the fighting compartment, and the breech was not strong enough to resist them until the rocket left the barrel, so they were channeled through ventilation shafts around the barrel with numerous exit holes surrounding the muzzle. The result was a spectacular flash when the weapon was fired. Because of this, the Sturmtiger had to move after each shot because its position was revealed to the enemy. The launcher barrel was later fitted with a steel ring as a counterweight to improve elevation and aiming. Sturmtiger could demolish any building or other target with a single shot, but it could carry only 14 rocket projectiles inside the superstructure. Twelve projectiles were stored in two stowage racks, one more in the launcher and another on the load-ing tray. Most vehicles carried only 13 rounds, without the one on the loading tray. The vehicle was equipped with a hand-operated lifting crane mounted on the right rear of the superstructure. This was used to load projectiles into the vehicle and needed the entire crew of five to operate.
"...up to 8ft. of reinforced concrete." Hmmm
