The nominal diameter of a projectile. For most modern munitions, this is expressed in millimetres (e.g. 82 mm mortar projectile), but older artillery gun projectiles may be described in inches.
Israeli illumination munitions—often finished in a distinctive yellow—are sometimes mistaken for high explosive munitions by observers more familiar with the NATO or U.S. marking systems. This image shows an M485-pattern illumination projectile, a base-eject type that uses a parachute-retarded canister containing a powerful candle to illuminate the battlefield.
The M825A1 155 mm smoke projectile makes use of white phosphorus (WP) to generate a brilliant white smoke. Whilst WP does have incendiary effects, the method of dispersal in the case of the M825A1 is optimised for screening and marking purposes. (ARES)
This image depicts an M117-series unguided aerial bomb. Belonging to a class of weapons referred to as ‘demolition bombs’—which use Tritonal or similar explosive compounds to generate a more powerful blast effect than TNT or Composition B—the M117 is an American design which dates to the Korean War era and is rarely seen in service with modern armed forces. (ARES)
This munition is assessed to be one of the Small Diameter Bomb (SDB) I variants (GBU-39 series), rather than one of the SDB II 'StormBreaker' (GBU-53 series) munitions, on the basis of contextual information. 'Small Diameter Bomb' is the manufacturer's terminology, whilst 'GBU-39' is the U.S. Air Force designation (also used by many other operators). (ARES)
Some artillery projectiles, such as this M150 type, use a hexachloroethane-based composition (HC) to generate smoke for screening or marking purposes. In many armed forces, HC smoke munitions have partially replaced those relying on white phosphorus for similar effects. (ARES)
107mm spin-stabilized rockets of this design are often utilized by non-state actors in an indirect fire role. Like the original Chinese models that they are copied from, they do not require more than a simple electric power source and a rudimentary launch platform to achieve an acceptable level of accuracy. (ARES)
The various Iranian Qaem-series guided air-delivered bombs can be difficult to differentiate from one another. In this case, the wing (forward fin) assembly distinguishes this Qaem-5 from the visually similar Qaem-1. Note also that the name 'Qaem' has applied by Iran to other, unrelated munitions. (ARES)
Many guided (or otherwise complex) munitions like this one are marked with additional information on individual assemblies or components. This can include information on sub-contractors that produced or integrated specific parts of a munition. (ARES)
The M-54 ‘high-drag’ series of Soviet/Russian air-delivered bombs can be distinguished by two key identification features: 1.) the ballistic ring located in the forward portion of the bomb (missing in this example); and 2.) the presence of two or four rectangular, longitudinal ‘levelling bars’ (two can be seen in this example). (ARES)
Russian air-delivered cluster bombs, such as this one, are often named using a designation that is a compound of the names of the cargo (carrier) bomb and the submunition it carries. For example, this RBK-500 unguided, air-delivered cluster bomb carries 268 PTAB-1M HEAT submunitions, and is thus designated the 'RBK-500 PTAB-1M'. (ARES)
This component is one of four pneumatically controlled canards from the guidance section of a Paveway II precision guided munition (PGM) conversion kit. When a Paveway II conversion kit is fitted to a MK 82 series unguided air-delivered bomb (note markings), the munition receives a GBU-12 series designation. (ARES)
The Brimstone is a series of British-designed guided missiles that can be launched from air, land, or sea platforms. The United Kingdom first provided Ukraine with the Brimstone I missile in 2022 and exports have continued since, more recently believed to include the Brimstone II model. In Ukraine, Brimstone-series missiles have been exclusively launched from ground-based and sea-based platforms as of May 2024. (ARES)
These S-25-O air-to-surface rockets are each loaded into a single-barrelled O-25 rocket launcher (sometimes called a 'launch tube' or 'rocket pod') that is affixed to an aircraft hardpoint. The over-calibre high explosive fragmentation warhead (of 420 mm in diameter) protrudes from the front of the tube. (ARES)
This artillery projectile is a non-lethal type designed to carry propaganda leaflets. Externally, it strongly resembles other variants carrying lethal payloads, although this particular model has a distinctive all-red colour. The leaflets are expelled from the base of the munition by the action of a small explosive charge, after a set amount of time has elapsed after firing (determined by the fuze). (ARES)
Whilst most mortars are smoothbore guns, some have a rifled bore. These M1101 120 mm mortar projectiles feature a 'pre-rifled' driving band—that is, a driving band with grooves cut at the factory to fit the mortar's rifling. (ARES)
Not all munitions have a lethal purpose. This is a type of ‘carrier’ or ‘cargo’ munition designed to carry and dispense a non-lethal payload—in this case, propaganda leaflets. (ARES)
This image depicts a Ukrainian-made version of the Soviet-era OF-25 152 mm artillery projectile, the designation of which is not publicly known at this time (May 2024). The yellow base colour was commonly found in batches produced by Ukroboronprom in late 2022. Later batches returned to a grey base colour. (ARES)
The OF-NMR is a rocket-assisted mortar projectile, which uses a solid-fuel rocket motor located in the cylindrical portion of the body, below the ogive, to extend its range. Rocket-assisted mortar projectiles are rarely encountered. (ARES)
The “+” marking is a weight classification symbol which indicates standard deviation. One “+” sign indicates a deviation from 0.33% to 1.00% of the stated weight. (ARES)
