[edit] Range of M107 175mm SP Gun

To answer the previous discussion question, yes, the tabular firing table (TFT), the document that lists data required to fire the weapon at standard conditions, lists the range with a standard weight projectile at 800 mil elevation (elevation for maximum range) as 32,800 meters.

On a related matter, this gun has often been maligned as being terribly inaccurate, with anecdotal statements that the gun "wouldn't come within a couple of kilometers of a target." The highest range probable error (the distance within which half the shots at a given range will statistically fall), which occurs at the maximum range of 32.8 km, is 74 meters. Expressing that as a percentage of range gives 0.23%; this is comparable to contemporary howitzers.

Having fired the gun under field conditions, I can personally attest that, firing lower charges at shorter ranges, the gun was accurate enough to provide effective fires on target. Firing the lowest charge, with a spacer behind it to ensure consistent placement of the propelling charge in the chamber, we were able to achieve target hits, which are uncommon with any indirect fire weapon.
