This domain of the catalogue covers the initiation components listed for artillery and mortar ammunition and for aircraft bombs. Line items include mechanical point-detonating fuzes, electronic time and proximity fuzes, multifunctional fuzes, percussion and electro-percussion gun primers, fuze setting devices and one anti-tank mine. Each entry carries the designation its record gives, where there is one, together with the figures its own source records, which may include the ammunition named, mass, connecting thread, safety distances and stated storage life.
The artillery fuze line items cover the UTIU, UTI, UT-PE, UB and UTE designation families listed for gun and howitzer projectiles. UTIU M15, UTIU M02, UTIU M02-P1, UTIU M85P1, UTIU-M72 B1 (AU-18) and UTI M68P1 are mechanical point-detonating fuzes; UT-PE M69 and UT-PE M87P1 are piezoelectric fuzes recorded for HEAT-T shells; UB M12 is a proximity fuze with contact-impact back-up; UTE M03 is an electronic time fuze supplied with a booster. Each record carries the figures its own source sets down, and names projectiles where the source lists them.
The mortar fuze line items run across the UT-M68, UT-M88, UT M18, PD UTU-M93, UTU M93P1, TP-M67 P1, ETSQ M365 and MBU M18 designations. UT-M68 P1 is a superquick impact fuze, while UT-M68 P2 and UT-M88P1 are mechanical point-detonating impact fuzes with superquick action; PD UTU-M93 P1 and PD UTU-M93N add a superquick or delay mode chosen by a mode selector, and UTU M93P1 records superquick and delay action; TP-M67 P1 is a zirconium-based pyrotechnic time fuze offered in 60 mm and 81/82 mm versions; ETSQ M365 is an electronic time fuze; MBU M18 is a proximity fuze; and UT M18 carries the mechanical interfaces the source records between shell and container.
A mechanical point-detonating fuze with safety and arming device that lets standard 60 mm, 81/82 mm and 120 mm HE mortar shells be dropped from an aircraft-mounted carrier, providing superquick fragmentation action and the mechanical interfaces between shell and container.

Projectile and bomb fuzes - electronic time, proximity, multifunction and impact fuzes
This group holds the nine line items the source records simply as fuzes. UB M16 is a proximity fuze working on the Doppler effect and UMF M16 a multifunctional fuze combining proximity, timing and superquick impact. UTE M10A1, UTE M03 without booster and UTE M10 without booster are electronic time fuzes with setting ranges recorded between 3 and 200 s. UTIU M72B2 and UTIU M72B3 are mechanical point-detonating nose fuzes of 0.42 kg. AUFK M-91 and the vAF-M17 with its vFI-M17 initiator are bomb fuzes. Where a mass is stated it runs from 0.42 kg to about 2 kg.
An impact, inertia-type electronic-mechanical fuze for high-explosive aircraft bombs with or without a drag chute, offering super-quick (T) and delay (U) action selectable by a manual mode selector and fitted with an armed/unarmed status indicator.
