Why helicopters do not replace the mine-countermeasures team

Is mine sweeping now mostly performed by helicopters?

No: helicopters are one option, while ships, divers, uncrewed craft, and hydrographic support remain central to mine countermeasures.

The United States has experimented with helicopter-based mine sweeping, but it is not a universal modern solution. Mine-countermeasures forces still use crewed surface ships, divers, uncrewed surface vessels, and uncrewed underwater vehicles. Hydrographic ships contribute a wide-area environmental and anomaly picture before specialized assets close in. The division of labor reduces risk and lets each platform work at the scale its sensors and operators suit best.
