Regarding the Soviet era 240 mm mortar we have the comments of the GRU defector Suvorov:
"I have actually seen 12 240 mm mortars in action together. These fire . . . 100 kilogramme bombs [about 220 pounds]. Within twenty minutes, each mortar fired 15 bombs. This represented, as I later calculated, a total of 18 tons of explosives and cast-iron splinters. I found the noise absolutely staggering. it was amazing that men could retain their sanity in the midst of it. While the firing was in progress, one had the impression that thousands of tons of explosive were going off each second and the whole process seemed to last an age. The astonishing destructive power of these mortars makes up for any inaccuracy in aiming or in dispersion."
FURTHERMORE ACCORDING TO SUVOROV THAT BIG-BORE [240 mm] CONSTITUTES AN ADVANTAGE WHEN DELIVERING A NUCLEAR MUNITION ON THE TACTICAL BATTLEFIELD!!
"The outstanding simplicity, reliability and case of maintenance of the 240 mm mortar are vital qualities, and they played a decisive role when the moment came to decide which should be the first artillery weapon to fire nuclear projectiles. it was an obvious choice and it is now many years since it was selected for this role. it was also a good choice, being comparatively small,, maneuverable and easier to conceal than a gun. At the same time, it has a huge caliber, which solves several technical problems. Its muzzle velocity is considerably lower than that of a gun or a howitzer. the is there fore no danger that the bomb will explode as it is fired or that it will detonate accidentally."
AN ATOMIC MUNITION FIRED FROM A MORTAR NOT SUBJECTED TO CONVENTIONAL TUBE ARTILLERY PROJECTILE "FORCES" OF VELOCITY AND SPIN THAT MIGHT DAMAGE THE INTERNAL DETONATING MECHANISM OF THE NUCLEAR WEAPON!!
EVEN WITH A SMOOTH-BORE MORTAR AN ATOMIC DETONATION NOT NEEDING A WHOLE LOT OF ACCURACY PIN-POINT!
