Manufacturer catalog
Multiple contractors identifies U.S. Navy mine systems whose public fact files assign production to more than one contractor rather than a single named prime. The connected records are Quickstrike naval mines, a family of aircraft-laid shallow-water mines that combine Navy mine hardware, target-detection devices, bomb bodies or purpose-built cases, and later precision-delivery kits across a distributed ordnance supply base.
2 weaponsThe public Navy mine fact file lists the general contractor field for U.S. Navy mines as "Multiple," reflecting a program-level industrial base rather than one corporate manufacturer. For the Quickstrike family, that public description covers Mk 62 and Mk 63 mines converted from 500-pound and 1,000-pound general-purpose bombs, plus the Mk 65 thin-walled 2,000-pound mine case.
Open Navy and NAVSEA material also shows how the production context extends beyond finished mine bodies. NAVSEA's mine-warfare program briefing identified Sechan Electronics work on the Mk 75 safe-and-arm device for Quickstrike Mk 62, Mk 63, and Mk 65 mines, while later NAVSEA reporting on Quickstrike Extended Range described a working group involving NSWC Panama City Division, fleet mine-warfare personnel, the Navy's Strike Planning and Execution Program, Boeing, and other stakeholders. This record therefore treats the manufacturer name as a sourced multi-contractor U.S. Navy mine-program attribution.
The Mk 62 is the 500-pound Quickstrike mine. The Navy fact file describes Mk 62 and Mk 63 as converted general-purpose bomb bodies laid by aircraft in shallow water, and lists the U.S. Navy mine program contractor field as multiple contractors.

The Mk 65 is the 2,000-pound Quickstrike mine using a thin-walled mine case rather than a bomb body. It shares the Navy mine fact file's multiple-contractor program attribution.
Sources: U.S. Navy Mines, National Academies Naval Mine WarfareThe Navy fact file says the Quickstrike Mk 62, Mk 63, and Mk 65 aerial-delivered mine series were first deployed in 1983, establishing the current U.S. Navy Quickstrike family connected to this manufacturer attribution.

The National Research Council's naval mine warfare study described the Quickstrike family as part of the U.S. mine inventory and warned that the nongovernmental mine-development and production industrial base had declined sharply after reduced Navy mine-development effort.

A NAVSEA mine-warfare program briefing listed continued development of the Mk 75 safe-and-arm device for Quickstrike Mk 62, Mk 63, and Mk 65 mines with Sechan Electronics, illustrating the component-level contractor structure behind the Navy's multiple-contractor field.

NAVSEA reported that NSWC Panama City Division hosted a Quickstrike Extended Range working group in July 2025 with engineers, logisticians, fleet personnel, the Navy's Strike Planning and Execution Program, Boeing, and other stakeholders supporting the Mk 64 Mod 5 Underwater Mine.

Multiple contractors is not a single legal entity with one headquarters, ownership structure, or corporate website. The sourced scope is the U.S. Navy mine-program contractor field and the connected Quickstrike systems; individual weapon records retain system-specific technical and media sourcing.
