There are two versions of this round produced. The HE-OM-1 can accept standard NATO fuzes while the HE-OM-2 accepts standard US fuzes. In the latter case an adaptor ring is fitted to the thread in the projectile body. This munition is marketed by Alenia Difesa, Otobreda Division.</p><h2>Description</h2><p>The 76 mm HE-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. The projectile interior is compression loaded with Composition A-3 (RDX 91 per cent, Wax 9 per cent). 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 training round used for the 76 mm HE-OM is the TP-OM. This utilises a monobloc steel projectile containing an inert filling. The TP-OM has the same handling and ballistic characteristics as the HE-OM. To reduce training costs, the South African company NASCHEM has produced a point-detonating fuze, the PD M9030, to be fitted to 76/62 projectiles in place of proximity fuzes during training.</p><h2>Authorised fuzes</h2><p>Prox TB 76, VTPA FB 76, UA 3005/05, UA 3018, AEG MAZ, MK 404 IR, Fuchs M8953A1 PD OP 76 Mod 1, M557, L85, M9030 Equivalent rounds BRAZIL</p><p>BRAZIL</p><h2>Manufacturer</h2><p>FI Indústria e Comércio Ltda</p><p>Type: HE</p><p>Description: Standard specifications.
