Mk 65 Quickstrike Mine

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. REVIEW NUMBER 4 Q1. What components are used on the Mk 55 mine for drop stability? Q2. What is the suspension of the Mk 55 mine? 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. REVIEW NUMBER 5 Q1.
