I'm pretty sure that all the old wooden minesweeps have been
decommissioned.

The Navy started acquiring fiberglass minesweepers approx 20
years ago (and that's not new). Most minesweeping nowadays
appears to be done by helicopter, assisted by SEAL teams
(who in turn are assisted by specially trained real seals &
porpoises)

I don't know if this will work, but here is a link to a
MS-Powerpoint article about minesweeps & minesweeping that I
thought was excellent
