OFM round

Also known as
  • OFM
  • 120 mm OFM round
  • 120 mm OFM ammunition

The OFM round is a 120 mm ammunition label associated with Russia's 2S40 Floks wheeled gun-mortar. Defense Express lists OFM alongside OFS 13 and Kitolov-2M and reports about 7.2 km range from the Floks, while Rostec and Army Recognition describe the platform as able to fire both mortar-style and rifled-projectile ammunition. The cited public sources tie OFM to Floks compatibility rather than standalone battlefield use, so this remains a relationship-only ammunition page.

Defense Express reports that the 2S40 Floks fires an OFM round and gives the OFM option a reported range of about 7.2 km; Rostec and Army Recognition describe the same platform as a 120 mm system able to use mortar-style and rifled-projectile ammunition.

Source limit

The cited sources identify conflict use of the Floks firing platform, but do not separately document OFM rounds being fired, supplied, captured, or recovered in a named conflict.

Floks Ammunition Context

Public sources describe OFM through the 2S40 Floks ammunition set, not as a separately documented munition family. Defense Express gives OFM a shorter reported range than OFS 13 and Kitolov-2M, while Rostec and Army Recognition describe the Floks gun as accepting both mortar-style and rifled-projectile ammunition.

2S40 Floks, 120 mm wheeled self-propelled howitzer/mortar, ArtilleryArtillery2S40 Floks120 mm wheeled self-propelled howitzer/mortarThe 2S40 Floks is a Russian 120 mm wheeled self-propelled gun-mortar developed by Burevestnik under the Nabrosok artillery program and mounted on an armored Ural-4320 6x6 chassis. Open reporting ties it to Russian battlefield use in Ukraine from October 2023, where Ukrainian drone units documented strikes against newly fielded systems while Rostec and defense references describe the platform's combined mortar, howitzer-style indirect-fire, and direct-fire roles.

MSM Group lists the modernized round with a 43.55 kg fuzed projectile mass, a 10 kg explosive filling, and 40 km class range from a 52-caliber gun. Public sources support this page as a relationship-only ammunition record through product data, transfer records, and howitzer compatibility context, not through direct conflict-use evidence for the exact projectile.

Forecast International identifies the 2S23 Nona-SVK's 2A60 weapon as firing HEAT ammunition for direct-fire applications, while specialist munition references identify the 3VBK14/3BK19 round as a documented 120 mm HEAT-FS-T load for armored-target engagements.

Official records document 155 mm artillery rounds in Ukraine's wartime ammunition supply and in coalition M777A2 fire missions against ISIS, while manufacturer lines show high-explosive, extended-range, training, modular-charge, and specialty projectile examples.

It gives Russian artillery units a compact turreted vehicle able to fire mortar-style high-angle missions, direct fire, and some guided 120 mm ammunition, but public reporting suggests only a small fleet reached service before examples appeared in Ukraine.

Forecast International lists smoke among the 120 mm ammunition types fired by the 2A60 Nona rifled ordnance on the 2S23 Nona-SVK, while Army Recognition describes the tracked 2S9 Nona as firing smoke rounds in its indirect-fire role. Modern 120 mm smoke products from STV GROUP, Nammo, and Hirtenberger show the class spanning visible and infrared screening, red-phosphorus payloads, white-phosphorus smoke, and other smoke fills depending on the round.
