The Alenia Difesa 76 mm Flash Non-Frag (FNF-OM) is each 76 mm FNF-OM is a fixed round with the projectile rigidly secured to the brass cartridge case by a crimping ring which engages in a groove on the wide copper/gilding metal drive band. The boat-tailed projectile body is a monobloc assembly made from a special high-quality steel. Each 76 mm FNF-OM projectile is filled with an inert compound and contains a flash charge weighing 94 g, consisting of a mixture of a flash composition and black powder, to provide a
flash and sound indication when the fuze functions. The brass cartridge case (72 per cent copper, 28 per cent zinc) has a base-mounted P85 percussion primer and is filled with 2.3 kg of M6 + 2 single-base multiperforated (19-hole) propellant. A mixture of wax and titanium in a fabric liner is glued inside the cartridge case to act as an anti-wear additive. The primer is normally protected by a clip which is removed before loading. The 76 mm Flash Non-Frag (or Non-Fragmentation) FNF-OM rounds were developed by the Otobreda Division of Alenia Difesa (formerly OTO Melara) for training use when fired against target drones, towed drogues or other training targets. They can also be utilised for functional firing tests of fuzes. There are three types of 76 mm FNF-OM round. The FNF-MOM corresponds to the MOM round and can accept the FB 371 fuze. The FNF-OM-1 can accept all fuzes valid for the HE-OM-1 and HE-PFOM-1 while the FNF-OM-2 can accept all fuzes valid for the HE-OM-2 and PFOM-2. All 76 mm FNF-OM rounds are mechanically interchangeable with all other types of 76/62 ammunition. Applications include otobreda 76/62 MMI; Otobreda 76/62 Compact; Otobreda 76/62 Super Rapid; Otobreda 76/62 Above Deck; 76 mm self-propelled AMRAD OTOMATIC air defence tank.
