Mk 6 Miscues

I'm delighted to have Don's recollections of screw-ups, mishaps and other adventures. Here are a few more.


One day, off Coronado, the YFU planted 10 Mk 6 Mod 14 drill mines (2.5-ft. case depth) then we tried to hit the mines with the YFU. The mine cases were painted white with red stripes so they would be easy to spot. The YFU's skipper (E-6) had a hard time seeing "dead ahead" mines because of the bow ramp. I climbed up the bow ramp and pointed to the mines when we got close. Try as we might after an hour of violent maneuvering we still hadn't scored a hit on any of the mines. The current was just strong enough to cause the mines to "dip" to a depth a little deeper than the YFU's draft. However, when the current slackened a bit, the skipper came up with a good idea. He maneuvered down-current of the mine line and let the current and wind carry the YFU broadside to the mine line. We popped five "special" mine detonators on the first pass. An acoustic detection device (Queen gear; possibly because of the shape of the device) lowered over the side indicated mine fires. The special detonators didn't really explode they just popped the cap off the end. For safety reasons, the same-type detonators were used on the Mk 6 Mod 15 drill mines where divers had to go down to 100-ft. and pull on one of the switch horns with at least 11-lbs. of force to get an actuation.
