Quickstrike

 

♦ Mk 62/63 (Quickstrike)

These conversions of standard streamlined bombs (Mks 82, 83, 84, respectively: 500, 1000, 2000 lb) supersede Destructors EX-52 through -54. The Destructors were magnetic-fuzed. These weapons can be dropped either on land (where they can be exploded by the magnetic signatures of vehicles) or in shallow water. Assembled very quickly using stored fuzes, Mk 62/ 64 are called Quickstrikes. All have standard thick-walled bomb casings, and their tails are adaptable to parachutes.

 

♦ Mk 62

Mk 62 was approved for service use in 1980. As of about 1986, plans called for procurement of 39,804 Mk 70/71 TDDs, plus 8000 Mk 57 and 2500 Mk 58. Actual TDD procurement: Mk 57: 1575 in FY83 and 1753 in FY84. Mk 58: 75 in FY84, 165 in FY85, 400 in FY87, 300 each in FY88 and FY89.

These weapons use 2 alternative target-detection devices (TDDs): Mk 57 (magnetic-seismic) and Mk 58 (magnetic-seismic-pressure). Presumably, seismic is, in effect, an acoustic sensor using sound as transmitted through the sea floor rather than directly through the water. These units are to be replaced by new Mk 70 and Mk 71 TDDs.

The QUICKSTRIKE Service Mine Mk 62 is an explosive-loaded (H-6 fill) bottom mine operationally planted by personnel flying B-52H Stratofortress, F/A-18A/D Hornet, F-14A/D Tomcat, B-1B Lancer, B-2A Spirit, or 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.

This 500-pound mine consists of a thick-walled general purpose (GP) Bomb Mk 82 incorporating an Arming Device Mk 32, and a Fin Mk 15, Fin BSU-86/B, or Tail Section Mk 16. The mine uses a Target Detection Device (TDD) Mk 57 (magnetic and seismic sensors) to detect stimuli generated by enemy vessels. The mine case is painted either olive drab or gray (new color).

Six OAs exist for the QS Service Mine Mk 62. For OAs 02 and 03, a Fin Mk 15 is fitted. A Fin BSU-86/B is used for OA-09. A Tail Section Mk 16 is used for OA-06 (F/A-18), OA-12 (B-1B), or OA-13 (B-2A).

The QUICKSTRIKE Laying Mine Mk 62 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 B-52H, F/A-18A/D, B-1B, B-2A, or P-3C aircraft in the techniques of carrying mines and planting minefields.

This mine consists of an inert-loaded GP Bomb Mk 82 incorporating an inert-loaded Arming Device Mk 32 and an operational Fin Mk 15, Fin BSU-86/B, or Tail Section Mk 16. For MMS Mk 5 recovery with either fin, a marine mammal recovery attachment and spacer is installed in the rear fuse well. For Tail Sections Mk 16, a special grabber mechanism mates with the tail’s access holes when MMS Mk 5 recovery is used. The mine case is painted either white with orange stripes or orange with white stripes.

Six OAs exist for the QS Laying Mine Mk 62. For OAs 02K and 03K, a Fin Mk 15 is fitted. A Fin BSU-86/B is used for OA-09K. A Tail Section Mk 16 is used for OA-06K (F/A-18), OA-12K (B-1B), or OA-13K (B-2A).

 

♦ Mk 63

The great advantage of this program is that the United States need not stockpile large numbers of bottom mines. Instead, it can stockpile an equivalent number of specialized exploders. The logic is much the same as for the standard U.S. raided bombs, which are assembled by adding special modules to standard Mk 80-series streamlined bombs.

Quickstrike was conceived as a new series of bottom influence mines, to enter service in 1976, to attack submarines, surface ships, and fast patrol craft. Initially the program called for 2 configurations, 500 and 2000 lb. The CNO Tactical Air Armament Study directed that the 500-lb Advanced GP Bomb (AGPB) be used for the smaller Quickstrike; the larger Quickstrike was designed to be adaptable as a demolition bomb in the AGPB family. Both were to be air-deliverable, and the 2000-lb weapon was intended for air and submarine delivery. Quick-strike was intended to replace the earlier Mks 25, 36, 52, and 55 bottom mines and Destructors Mk 36 and Mk 40.

The development of the Quickstrike series and its associated TDDs is justified on 2 grounds. First, the existing devices, as well as the Mk 52 series ground mines, were all compromised in Vietnam. Second, they are all becoming difficult to maintain and are no longer being manufactured. For example, their batteries must be stored under refrigeration. Quickstrike's design emphasizes ease of maintenance and also ease of mine preparation for use. All the Quickstrikes are air-delivered. The corresponding submarine-delivered bottom mine is Mk 67; there is no corresponding ship-delivered bottom mine.

The QUICKSTRIKE Service Mine Mk 63 is an explosive-loaded (H-6 fill) bottom mine operationally planted by personnel flying B-52H Stratofortress, F/A-18A/D Hornet, or 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.

This 1,000-pound mine consists of a thick-walled general purpose (GP) Bomb Mk 83 incorporating an Arming Device Mk 32 and a Fin MAU-91A/B or Tail Section Mk 12. The mine uses a Target Detection Device (TDD) Mk 57 (magnetic and seismic sensors) to detect stimuli generated by enemy vessels. The mine case is painted either olive drab or gray (new color).

Three OAs exist for the QS Service Mine Mk 63. For OAs 02 and 03, a Fin MAU-91A/B
is fitted. A Tail Section Mk 12 is used for OA-06.

The QS Laying Mine Mk 63 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 B-52H, F/A-18A/D, or P-3C aircraft in the techniques of carrying mines and planting minefields.

This mine consists of an inert loaded GP Bomb Mk 83 incorporating an inert-loaded Arming Device Mk 32 and an operational Fin MAU-91A/B or Tail Section Mk 12. For MMS Mk 5 recovery with a fin, a marine mammal recovery attachment and spacer is installed in the rear fuse well. For MMS Mk 5 recovery with a tail, the tail is fitted with two steel bail weldments (inside the tail’s access holes) painted white. The mine case is painted either white with orange stripes or orange with white stripes.

Four OAs exist for the QS Laying Mine Mk 63. For OAs 02K and 03K, a Fin MAU-91A/B is fitted. A Tail Section Mk 12 is used for OA-06K. Finally, OA-06KQ signifies a Tail Section Mk 12 fitted with the two bail weldments.
