They are used against submarines and surface targets.
The mines are upgraded by installation of the Mk 130
conversion kit, Mk 130 battery, and flight gear.
Mk 65 Quickstrike Mine
The Mk 65 quickstrike mine (fig. 5-13) is a 2,000
pound, air-laid, all modular, influence-actuated, bottom
mine. The Mk 65 is used against submarines and
surface targets. The Mk 65 consists of a Mk 65 mine
case, a Mk 45 safety device arming group with a Mk 2
arming device, a Mk 57 target detecting device and a
Mk 7 tail assembly.

SAFETY PRECAUTIONS
LEARNING
OBJECTIVE:
Recognize
the
safety precautions for handling mines and
torpedoes.
Handling mines is a specialized job. If you aren't
qualified, don't disassemble the mines or their
components. You should follow the same safety
precautions for mines as you follow when handling
bombs.
To conform to safety and ammunition stowage
requirements, mines are normally received aboard ship
in
assembly
configurations
C
or
D.
Aviation
Ordnancemen are not required to assemble mines, but
they are required to be qualified and certified in mine
handling and aircraft loading procedures.
A Mobile Mine Assembly Group (MOMAG),
composed of personnel from the Mineman rate, is
responsible for the proper assembly of all mines. It is
the responsibility of the mine planting activity to notify
the MOMAGs of scheduled mine operations and the
exact dates their assistance will be required.
When a mine is jettisoned safe, the wires remain in
the clock starter and booster extender. This prevents
them from operating after the mine submerges.
However, when the mine strikes the water, the arming
wires
may
pull
free.
Hydrostatic
pressure
or
countermining shock can cause the wires to shear. Also,
after a mine is submerged for a long period, the wires
can corrode and break. No mine is jettisoned safe in
water that is less than 800 feet (243.8 meters) deep with
positive assurance that it isn't a hazard. Depths greater
than 800 feet will crush or flood the mine case, making
the mine inoperative.
When handling mines during preflight operations,
follow the same general handling techniques you use
for bombs or torpedoes.
