Modular - Quickstrike-type
♦ Quickstrike Mk 64/65
A 2390-lb modular mine (29 in across fins x 128 in), Mk 65 is the only Quickstrike not converted from a standard bomb. Un-like Mk 64, Mk 65 has a special thin-walled casing and a special arming device. Aerojet received the Mk 65 contract on 15 April 1982. Mod 0 uses a Mk 57 TDD; Mod 1 uses a Mk 58 TDD.
In 1985 Aerojet, the U.S. manufacturer, and Misar of Italy agreed to allow Misar to market Mk 65 in Europe. A new family of microprocessors developed by Misar will replace the U.S. Mk 58 multisensor TDD (trigger unit).

Mk 65 was approved for service use in 1983. Procurement: 307 in FY82, 579 in FY83, 600 in FY84, 524 in FY85, 1445 in FY86, 500 in FY88, and 524 in FY89, for a total of 4479 against a planned total of 4500. As of 1985, plans called for 559 in FY85, 743 in FY86, 743 in FY87, and 777 in FY88; the new schedule brought out the planned production run early. Actual procurement was 1445 in FY86; as of late 1986, plans called for 500 in FY88 and 524 in FY89 (none were bought in FY87).
The QUICKSTRIKE Service Mine Mk 65 is an explosive-loaded mine for operational planting by aviation personnel flying B-52H Stratofortress, F/A-18A/D Hornet, B-1B Lancer, and P-3C Orion aircraft. This mine is currently being flight tested on the F/A-18E/F Super Hornet with carriage approval expected in the near future. It was designed as a mine from the outset, using a thin-walled mine-type case filled with a PBXN-103 explosive mix vice the thicker bomb-type cases used by QUICKSTRIKE Mines Mk 62 and 63 filled with explosive mix H-6. The mine uses either a Target Detection Device (TDD) Mk 57 (magnetic and seismic sensors) or a TDD Mk 58 (magnetic, seismic, and pressure sensors) to detect stimuli generated by enemy vessels.
This mine weighs approximately 2,260 pounds, consisting of a mine case, nose fairing, and a Tail Section Mk 7. Its case is a steel cylinder 93 inches long and 21 inches in diameter at its largest point. A 16-inch portion of the aft end of the case tapers from 21 inches to 17.5 inches in diameter, at which point the tail is attached. The mine’s case is painted olive drab.

The QUICKSTRIKE Laying Mine Mk 65 is a recoverable, inert-loaded mine identical in size and weight to its Service mine counterpart. It is designed solely for training aviation personnel flying the same airborne platforms identified above for the Service mine variant.
The mine consists of a mine case, nose fairing, and an operational Tail Section Mk 7. The mine case is painted either white with orange stripes or orange with white stripes to enhance its visibility in the water and to help expedite recovery efforts.
Although this mine contains no explosives and does not explode as do Service mines, the Tail Section Mk 7 contains a low-level explosive device that is used to deploy the parachute once the mine is released from the aircraft. After release from the aircraft, impact with the water shears off the tail which uncovers a float assembly housed in the rear of the mine case. This float rises to the water’s surface to mark the mine’s underwater location.
