This is an insight that Antheil arrived at from his musical work, not from weapons engineering. The path from Ballet Mécanique to torpedo guidance is not obvious; it required someone whose mind moved between music and mechanism, and who was sitting across a table from someone who knew what problem needed solving.
## How Radio Jamming Actually Worked
To understand why the Lamarr-Antheil patent mattered, it helps to understand the actual problem of radio jamming in the context of wartime torpedo guidance.
A torpedo traveling through water cannot be tracked visually from a firing ship beyond a few hundred meters. Acoustic tracking — listening for the torpedo’s propeller sound — worked at short ranges but was impractical in combat conditions. Wire guidance, in which a thin wire connected the torpedo to the control station and allowed direct electrical steering, was used by some navies but had obvious limitations: the wire could break, entangle, or limit the torpedo’s range. Radio guidance, in which a surface operator controlled the torpedo’s steering through radio signals, offered greater flexibility but introduced the vulnerability of radio control.
A radio-guided torpedo operated on a specific carrier frequency. The operator on the surface ship transmitted steering commands on that frequency; a receiver in the torpedo detected those commands and activated the rudder accordingly. An enemy ship that detected the torpedo’s guidance frequency — which was possible using radio monitoring equipment — could broadcast on the same frequency at higher power, overwhelming the guidance signal and causing the torpedo to respond to the enemy’s commands instead. This was jamming in its most direct form: not destroying the signal but replacing it.
