Motor Minesweeper MMS 137 would have looked the same as her sister ship, MMS 192. Note, the Acoustic “hammer” on the bow in the up position used to sweep for acoustic mines and the drum on the stern for the LL cables used to detonate magnetic mines.
If you, your father or your grandfather have any additional information about this ship, crew lists, stories, photographs, please send copies of them to be added to our records and this website.
Thank you.

Motor Minesweeper's were purpose built, wooden, shallow draft, minesweepers with both SA and LL sweeping capabilities. SA is Sweep Acoustic, a device similar to a Kanga Hammer which makes a loud thumping noise which explodes acoustic mines. LL (double L) is a pair of electric cables which are towed parallel to each other on floats and emit a strong electric pulse which generates a magnetic field which detonates magnetic mines.
