A minehunter is a naval vessel that seeks, detects, and destroys individual naval mines. Minesweepers, on the other hand, clear mined areas as a whole, without prior detection of mines. A vessel that combines both of these roles is known as a mine countermeasures vessel (MCMV).

Description

A minehunter uses an imaging

charges
that are detonated remotely.

As minehunters will often be operating in close proximity to mines, they are designed so as to reduce their own

hull, or are degaussed to reduce magnetic signature.[7]

Minehunters are generally small,

Voith-Schneider cycloidal propulsor is commonly used, allowing the engine thrust to be transmitted in any direction. A number of modern vessels use catamaran hulls to provide a large, stable working platform with minimal underwater contact; this reduces draught whilst lowering acoustic transmission and reducing the fluid pressure
generated by the moving hull that may otherwise detonate mines with a hydraulic pressure trigger.

Coastal minehunter

Coastal minehunters are ships that are designed to find, classify, and destroy moored and bottom

submarines
.

Operation

Minehunters differ from

CAPTOR mine). To do this they have mine-hunting sonar and can act as motherships and support craft for ROVs and combat divers
. However, in some circumstances many minehunters can also destroy less advanced magnetic moored mines in the traditional manner.
