All fuzes and energetic components
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.
Point-detonating mechanical fuze of superquick, inertia and delay action for the 155 mm M107 projectile, waterproof, mass approx. 710 g.
Artillery proximity fuze functioning at 4 to 16 m burst height with contact-impact backup, electronic safety and 100 calibre muzzle safety.
Piezoelectric superquick nose fuze for 90 mm and 100 mm HEAT-T shells, with interrupted explosive train and short-circuited electrodetonator.
Piezoelectric superquick fuze for 122 mm 3BK-13 and 125 mm 3BK-14M HEAT-T shells, supplied as piezogenerator and bottom part.
Microprocessor electronic time fuze with booster for 105 to 155 mm HE, smoke, practice and cargo artillery projectiles, 3 to 200 s setting.
Point-detonating mechanical artillery fuze of superquick action for 76 mm HE projectiles, airtight, mass approx. 358 g.
Point-detonating mechanical fuze of superquick and delay action for 105 mm HE ER M02 and HE ER-BB M02 projectiles.
Point-detonating mechanical fuze of superquick and delay action for 105 mm HE M1 and 155 mm HE M107 projectiles.
Point-detonating mechanical fuze of superquick and delay action for non-rotating HE projectiles of 100, 115 and 125 mm, mass 410 g.
Point-detonating mechanical fuze of superquick, inertia and delay action for 122, 130 and 152 mm projectiles, set by sleeve turning and cap removal.
Tender documents call out the fuze type and action, the projectiles named as compatible, the safety standard, the arming conditions and the connecting thread. The entries here follow that order as far as their own sources go: point-detonating, piezoelectric, proximity or electronic time as the fuze type; superquick, inertia, delay or timed as the action; MIL-STD-1316B or MIL-STD-331C where the source cites a standard; and arming figures expressed as acceleration, with rotation in rpm and a connecting thread given only where the source records them.
UTIU and UTI denote the mechanical point-detonating fuzes, with recorded masses running from approximately 358 g for UTI M68P1 to approximately 710 g for UTIU M15. UT-PE marks the two piezoelectric fuzes, UB the proximity fuze and UTE the electronic time fuze with booster. What varies by model is the projectile list, the delay window, the drop and muzzle safety distances, the connecting thread and, for the models that state one, a storage period of five to fifteen years.
Where the source gives an ammunition compatibility, the record repeats it exactly: 155 mm M107 for UTIU M15; 105 mm HE ER M02 and 105 mm HE ER-BB M02 projectiles for UTIU M02; 105 mm HE M1 and 155 mm HE M107 for UTIU M02-P1; HE unrotating projectiles of 100 mm, 115 mm and 125 mm for UTIU M85P1; artillery projectiles cal. 122, 130 and 152 mm for UTIU-M72 B1 (AU-18); 76 mm HE projectiles for UTI M68P1; HEAT-T shells 90 mm M74 and 100 mm M69 for UT-PE M69; HEAT-T shells 122 mm 3BK-13 and 125 mm 3BK-14M for UT-PE M87P1; and special artillery ammunition 105 to 155 mm for UTE M03. UB M12 is listed with no ammunition compatibility at all, and no compatibility beyond those lists is stated.
Where the source states them, entries carry the safety standard, the interrupted explosive train, drop safety of 1.75 m or 3 m, muzzle safety from 2.5 m up to a minimum of 100 calibres, and the arming acceleration and rotation thresholds. Line items whose source sheet gives no such figure are listed without one.
