What voltage do Nixie tubes work?
Tubes ignite at 140-170 V, slightly varying by type. Once ignited, their resistance is very low so a series of resistors is necessary to limit the current, typically to 1-5 mA. The operational voltage of the Tube is 90-130 V depending on type. If the voltage drops below the turn-off voltage, the Nixie will go out.

What is towed torpedo decoy?
Towed Decoy is a programmable unit that emits wideband acoustic noise to mask own-ship noise. On the other hand, expendable decoys emits wideband noise to cut the engagement of the torpedo and emulates acoustic characteristics of own-ship to attract the torpedo in jammer and decoy mode, respectively.
