Shells fired electrically do not require which type of fuse?

Shells fired electrically utilize an electric match, which initiates the burst charge without needing a quick match fuse. A quick match fuse is designed for quick ignition in scenarios where a fast burn is required, typically for manually lit devices. However, when shells are ignited using electrical means, the rapid ignition provided by a quick match is unnecessary because the electrical signal directly ignites the charge.

In contrast, time delay fuses, standard fuses, and safety fuses serve essential roles in both electric and non-electric firing systems. Time delay fuses provide a delay before ignition, allowing for coordinated displays. Standard fuses ensure consistent burning for reliable ignition timelines, while safety fuses are crucial for protecting against unintended ignitions. Therefore, when employing electric firing systems for shells, a quick match fuse is not required, making it the correct choice in this context.
