Description
Technical Manual TM 9-1220-220-35 for M10 (T24E3) Ballistic Drive, June 1960
This Technical Manual TM 9-1220-220-35 covers the M10 Ballistic Drive, also designated T24E3, and is dated June 1960.
The publication is an official Field and Depot Maintenance Manual providing advanced maintenance information for this mechanical tank fire-control component.
Historical Significance
The M10 Ballistic Drive was part of the mechanical fire-control system used in the 105 mm Gun Tank M60. It acted as a differential drive between the ballistic computer and the tank’s associated rangefinder and gunner’s sighting equipment.
The drive transmitted calculated superelevation data, allowing the sighting system to incorporate the vertical aiming correction required for the selected ammunition and target range. This equipment represents the mechanical and analog fire-control technology used before digital fire-control systems became standard.
