A rare New Old Stock Demolition Charge Computing Tape, a precision field tool once issued to U.S. Army combat engineers for calculating the required explosives to breach or destroy specific targets. This original military-issue computing tape remains in very good unused condition and is a vital collectible for any military engineering or EOD-focused collection.

Historical Context

Before the widespread use of digital range calculators and modern software, U.S. Army engineers relied on mechanical tools like the Demolition Charge Computing Tape to determine the type and amount of explosives necessary for mission success. These tapes were designed to quickly show required charge weights based on structural composition, target thickness, and desired breaching effect.

Tools like this were especially important during World War II, the Korean War, and the Vietnam War, and were often carried by engineer officers and demolitions teams in both combat and training environments. Compact and field-durable, the computing tape allowed troops to make time-sensitive calculations under pressure, whether for bridge demolition, obstacle clearance, or defensive sabotage operations.
