ZEVS is an SLF transmitter of the Russian Navy near Murmansk for alerting deeply submerged submarines.

Because ZEVS works at an extremely low frequency of 82 Hertz, it only achieves extremely low signal data rates, but with a wavelength of around 3700 km, its signals penetrate the water as deep as possible - up to 300 m. Submarines dive into this depth in order to “hide” from reconnaissance using various methods. The frequency deviation for signal transmission is also in a very low range with a maximum of slightly more than 2 Hz.

ZEVS uses a ground dipole as a transmitting antenna , which is about 60 kilometers long.
