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.
Some tank gun projectiles may have fins affixed to an extended ‘tail boom’, in a similar manner to a mortar projectile. Note, however, that the cylindrical tail assembly is not perforated as it would be for most mortar projectiles. Tank gun projectiles are also more likely to be generally cylindrical, rather than lachrymiform (teardrop-shaped). (ARES)
This image shows a component believed to be part of the folding-blade assembly used in the AGM-114R-9X variant of the Hellfire missile. Blades are used in place of an explosive payload to create a kinetic weapon that achieves a practical level of lethality whilst minimising collateral harm. (ARES)
Little is known with certainty about the AGM-114-R9X variant of the Hellfire missile, although it has been associated with high-profile targeted killings including those of senior al-Qaeda figures. The weapon functions as a kinetic-impact munition, using pop-out blades—rather than an explosive warhead—to reduce the prospects of collateral harm. (ARES)
The image is of "a high-velocity shell fired from the main armament of a battle tank," Desmond Travers, former director of the Institute for International Criminal Investigations, told Airwars and AFP. "The calibre appears to be 120 mm, and the shell is fin-stabilised. The maximum effective range is five kilometers, but a skilled tank crew member should be able to hit a target the size of a car." (Airwars)
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)
The 57E6 series of missiles fired from the 96K6 Pantsir system use a two-stage design that is unusual for surface-to-air missiles of this type. The remnant seen in this image is part of the missile’s booster section, which accelerates the second stage to a high velocity before separating. The booster section uses a distinctive toffee-brown, filament-wound composite body. (ARES)
Although this munition started out life as a mortar projectile of the M492-pattern, it has been modified to be dropped from an unmanned aerial vehicle (UAV) and, in its present state, could not be fired from a conventional mortar. As such, it is correctly classified here as an air-delivered bomb. (ARES)
The fin assembly in the image bears a strong resemblance to those of other munitions employed in the same incident that have been identified as M49A2 mortar projectiles modified to be delivered by UAV. (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)
As a result of the rapid introduction of new models and variants during ongoing conflicts, sometimes a munition is issued with a provisional designation, or with no designation at all. In other cases, the designation is not yet known to researchers. (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)
The plum-coloured plastic ring at the nose of this mortar projectile (placed over its fuze) and the black plastic propellant cover (placed over its tail) are both fitted for transport and storage, before the projectile is loaded into a cardboard tube, and then packed into an outer crate. The propellant cover obscures the perforated cylindrical tail assembly in this image. (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)
The 120 mm 3-Z-2 incendiary mortar projectile contains 6 incendiary elements, four large and two small. These are hollow steel ‘cups’ filled with an incendiary mixture of an unknown type, but understood to be comparable in effect to thermite. (ARES)
