Unguided Munition
Munitions incapable of altering their flight path once fired, instead following a relatively predictable trajectory (typically a ballistic trajectory). Unguided munitions are generally less precise, and cheaper, than guided alternatives.
Analyst Note:
The two North Korean 120 mm high explosive (HE) mortar projectiles in this image are each fitted with five cloth bags affixed above the tailfins. These are incremental propellant charges (sometimes known as augmenting, auxiliary, or supplemental charges), the number of which can be varied along with a mortar’s elevation to adjust the trajectory and range of the munition when fired. (ARES)
Analyst Note:
This image shows two Iranian 130 mm high explosive (HE) artillery gun projectiles. Calibre (“130MM”) and functional type (“HE - TNT”) markings are visible on the right-hand example, whilst a lot marking (“LOT:10/202[…]”) is partially obscured. The “TNT” marking indicates that this munition uses a trinitrotoluene composition as its explosive fill. (ARES)
Analyst Note:
This 9M27K-series surface-to-surface cargo rocket is loaded with either 9N210 or 9N235 high explosive fragmentation (HE-FRAG) submunitions. These models are nearly identical in construction, differing primarily in the nature of the pre-formed fragments they carry. (ARES)
Analyst Note:
This image shows an Iranian 122 mm high explosive (HE) artillery gun projectile. Like several other munitions, it is described in Iranian sources—and, in this case, on the munition itself—only by reference to the weapon with which it is most often associated: the Soviet-designed 122 mm D-30 howitzer (often rendered ‘D30’, without the hyphen, in Iranian service). This munition is also marked to indicate it was produced in 2023. Interpreting munitions markings in this way, especially where they indicate recent manufacture, may provide evidence of ongoing supply during a conflict. (ARES)
Analyst Note:
The munition indicated in this image as a 152 mm high explosive (HE) artillery gun projectile manufactured in the Democratic People’s Republic of Korea (DPRK). (ARES)
Analyst Note:
This image shows an SUU-30H/B, an air-delivered dispenser which can be configured to carry different submunition payloads. These can include 217 BLU-61 A/B, 650 BLU-63/B, or 650 BLU-86/B or BLU-86 A/B. The munition can also carry inert payloads. The specific combination of payload and dispenser determines the ‘Cluster Bomb Unit’ (CBU) designation, with SUU-30H/B dispensers being paired with different payloads to form the CBU-58 and CBU-71 series. Contextual information suggests that this dispenser was part of a CBU-58/B cluster munition, but this cannot be established from an assessment of this image alone. (ARES)
Analyst Note:
MK 84 unguided air-delivered bombs can be fitted with a variety of tail kits, or with guidance kits which convert them into precision guided munitions (PGMs). When an air-delivered bomb impacts a building or the ground without functioning, the tail or guidance kit may be sheared off. With these separated from the munition—and in the absence of other identifying features, such as a seeker fitted to the nose of the weapon—it becomes very difficult to determine whether the bomb was guided or unguided. (ARES)
Analyst Note:
These R-122 ‘Grad’-type 122 mm surface-to-surface rockets were produced in North Korea. The example to the right is fitted with an F-122 impact fuze. Whilst a two-tone colour scheme is more common amongst those North Korean Grad rockets thus far identified in the context of the Ukraine conflict (these typically featuring a black forward section), uniformly coloured examples like this have also been identified previously. (ARES)
Analyst Note:
Two of the distinctive, black tailfins used on S8-series air-to-surface rockets are visible to front and left of the remnant material. (ARES)
Analyst Note:
Almost all cluster munitions, including this example, expel their submunitions during flight. The submunitions are often held in an internal frame, such as that visible here, prior to being expelled. Depending on the munition, these internal frames may be diagnostic for identification. They usually do not carry a significant explosive payload in their own right, and therefore often withstand the functioning of the munition relatively intact. (ARES)
Analyst Note:
The 9M27K3 surface-to-surface rocket is fitted with the 9N128K3 cargo warhead (seen here). This warhead carries a payload of 312 PFM-1 or PFM-1S scatterable anti-personnel landmines. (ARES)
Analyst Note:
The markings on this 9N128K3 cargo warhead indicate that it was produced in 1989 and fitted to a 9M27K3 rocket in 1990. (ARES)
Analyst Note:
The arming vane for a nose fuze (painted red) is visible on each of the two leftmost MAB-10B6 air-delivered bombs in this image. As the bomb falls, air passing over the arming vane causes it to spin, arming the fuze. (ARES)
Analyst Note:
The circles in this image indicate where the fixed fin assembly is connected to the bomb body. Fin assemblies such as this help stabilise the bomb as it falls, improving the predictability of the trajectory and thus precision. Fins also orient the bomb as it falls so that munition travels nose-down. Orientation of the bomb on impact can play a role in fuze functioning, as well as the distribution of explosive or other effects. (ARES)
Analyst Note:
This Iranian 60 mm mortar projectile is of the ‘Long Range’ type described without a specific model name in various Iranian export catalogues and other sources. The designation as marked on projectiles and packaging is variable, with observed formulations including “60mm H.E. L.R.”, “60mm H.E L.R”, and “60mm HE L.R”. Sometimes, as here, “60mm L.R” is followed by “HE / TNT”. (ARES)
Analyst Note:
This image shows what is probably just the body of an Israeli 155 mm smoke artillery projectile. Israel predominantly uses two varieties of 155 mm smoke munition: the M825 white phosphorous (WP) series of munitions, and the M150 hexachloroethane/zinc mixture (HC) munition. These munitions are externally near-identical, save for their markings. In this case, the markings are insufficient to determine whether the image shows an M825-series WP munition or an M150 HC munition. (ARES)
Analyst Note:
The 9M22S is essentially the ‘full-sized’ version of the shorter 9M28S surface-to-surface rocket previously recorded in the OSMP. Both rockets carry the same 9N510 incendiary warhead, but differ in the length of their rocket motor sections, and thus range. (ARES)
Analyst Note:
The 9M28S surface-to-surface unguided rocket carries the 9N510 warhead, which disperses burning thermite-type incendiary elements over a wide area upon functioning. This munition is designed to start fires in target areas vulnerable to incendiary attack, including forests, ammunition dumps, and fuel storage sites. (ARES)
Analyst Note:
This M107 high explosive (HE) artillery gun projectile is fitted with an RT180 multi-function fuze. The RT180 can be set to operate in point-detonating or proximity modes. The factory setting for the proximity fuze detonates the warheads an average of 9 metres above the target. (ARES)
Analyst Note:
This 9M27K-series surface-to-surface cargo rocket is carrying a payload of 9N210 or 9N235 high explosive fragmentation (HE-FRAG) submunitions. These submunitions are difficult to distinguish unless their external markings are visible, or a close examination is made. (ARES)
Analyst Note:
The M117 series of air-delivered bombs were historically referred to as ‘demolition bombs’, due to the more substantial blast effect they offer in comparison with so-called ‘general-purpose bombs’. This is achieved through the use of more energetic explosive compositions, such as Tritonal or Minol, which incorporate an oxidiser (typically aluminium powder). Today, munitions using such compositions are sometimes considered in the loose category of ‘enhanced blast munitions’, but the distinction between demolition and general-purpose bombs has largely disappeared. (ARES)
Analyst Note:
The crude launch arrangement depicted in this photograph shows the ease with which many simple rocket designs can be launched. Weapons such as this are used where precision fire is not a requirement; i.e., where the target might be a whole compound, neighbourhood, or settlement, rather than a specific building or vehicle. (ARES)
Analyst Note:
The M824 60 mm mortar projectile dispenses a parachute-retarded illumination flare which burns for 35 seconds. The tail portion of the munition (seen here) separates from the forward (body) portion and is sometimes found along the line of fire. (ARES)
Analyst Note:
This is an Iranian 60 mm mortar projectile, marked to indicate it is of the ‘high explosive, long-range’ type (“H.E L.R”). Both the munition body and fuze are marked to with the year of production (“2008”). Whilst the tan colouring is often indicative of Iranian-made munitions (especially where the fins are also painted), this is not diagnostic, and a combination of physical features and markings should be assessed to reach a positive identification. (ARES)

Analyst Note:
Markings on this 106 mm recoilless gun projectile indicate it is a M344A1 high explosive anti-tank (HEAT) round (“CH-106-M344-A1”) produced by Fábrica Nacional de Granada (“FNG”), Spain, in 1984 (“84”). The packing crate identifies the intended weapon as an M40A1 Cañón sin retroceso, or ‘recoilless rifle’ (“C.S.R. 106 M40 A1”). Other markings show that the round is fitted with an M509-type point-impact, base initiating (PIBD) fuze (“Espoleta PIBD M509”), and give additional details such as the expected muzzle velocity (“V₀”) of 503 m/s. (ARES)
Analyst Note:
This Iranian M91 81 mm mortar projectile is marked to indicate it was produced in 2009. The AZ111A2 fuze fitted to the projectile is also marked with the same year of manufacture. (ARES)
Analyst Note:
‘Khaibar-1’ is a designation given to a series of 302 mm rockets produced in Syria, possibly derived from the Chinese WS-1/WS-1B. The Khaibar-1 is also referred to as the M-302 or M302. (ARES)
Analyst Note:
This Iranian M48 120 mm mortar projectile is marked to indicate it was manufactured in 2008. A plastic bag cable-tied to the tail of the munition protects the auxiliary, or supplemental, propellant charges fitted to the round. (ARES)
Analyst Note:
This Iranian copy of the Chinese Type 63 107 mm rocket is marked with a red stripe and text to indicate it is of the high explosive incendiary (“H.E.I”) type. Markings also show that it was produced in 2007. (ARES)
Analyst Note:
These M485 series 155 mm artillery gun projectiles are painted yellow to indicate their functional type: illumination rounds. The M485 series of illumination projectiles are base-eject munitions that expel a parachute-retarded illuminant canister which casts light over the battlefield as it descends. (ARES)
Analyst Note:
The physical features, colour scheme, and packaging of these 120 mm mortar projectiles are all consistent with Iranian manufacture, but the markings are mostly obscured in this image. (ARES)
Analyst Note:
This is an Israeli 120 mm tank gun round, of the ‘armour-piercing, fin-stabilised discarding sabot – tracer’ (APFSDS-T) type. The physical features identify it as either the M322 or M338.
The projectile (penetrator) of this round has no explosive content and relies on kinetic energy to penetrate armoured targets. When a projectile is of a smaller calibre than the gun’s bore, a sabot is sometimes used to ensure the projectile is centred in the bore and to trap the gas from the propellant of the cartridge and propel the projectile. In flight, the sabot separates into two or more pieces, sometimes called ‘petals’, often found along the line of fire before the impact point. (ARES)
Analyst Note:
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)
Analyst Note:
The M329 is a multi-purpose tank gun projectile designed to engage a range of targets other than tanks. It is one of the few cluster munitions that takes the form of a tank gun projectile, dispensing six explosive submunitions over a relatively small area. It has also been referred to as the ‘APAM 120’, describing its functional role (‘anti-personnel/anti-materiel’) and calibre (120 mm). (ARES)
Analyst Note:
In this image, part of the distinctive internal 'X-rib' arrangement is visible protruding from the base of an M825-series white phosphorus smoke projectile. This is a useful diagnostic feature that can be used to distinguish remnants of these munitions from those of similar projectiles (such as those using a hexachloroethane/zinc smoke composition) if markings are not visible (ARES)
Analyst Note:
The remnants shown in these linked images have been falsely identified in Russian sources as chemical munitions. This image clearly exhibits the marking “NBK DM 1216”—the ‘NBK’ standing for the German Nebelkörper (‘smoke element’)—identifying this as one of four DM 1216 hexachloroethane/zinc (HC) smoke elements dispensed by the German DM 105 155 mm artillery gun projectile. Video of the incident shows all four elements being ejected from the base of the projectile in flight. (ARES)
Analyst Note:
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.
Analyst Note:
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)
Analyst Note:
This image depicts either a 9M27K or 9M27K1 cargo rocket (cluster munition). The 9M27K carries the 9N210 high explosive fragmentation (HE-FRAG) submunition, whilst the 9M27K1 carries the 9N235 HE-FRAG submunition (ARES).
Analyst Note:
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)
Analyst Note:
Contextual information suggests that this is likely a 9M22S unguided incendiary rocket (see External Research section), but this cannot be confirmed on the basis of this image alone. (ARES)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
The MK 84 series of unguided air-delivered bombs can be converted to precision guided munitions by being fitted with guidance kits such as the Joint Direct Attack Munition (JDAM), SPICE 2000, or Paveway series. This MK 84 is also marked with a variant designation “MOD 4”. (ARES)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
Cargo rockets often use an internal frame to manage the correct carriage and expulsion of submunitions. These internal frames frequently survive largely intact after the munition has functioned, and may be diagnostic in identifying a munition by type, series, or model. (ARES)
Analyst Note:
The large fragments in this image are typical of 'natural' fragmentation resulting from the rupturing of a thick-walled munition (in this case, an artillery projectile) by the functioning of its explosive payload. (ARES)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
This image features both delivered (the two left-most munitions) and undelivered munitions of the same model.
Analyst Note:
Like the more common 9M22S rocket, the 9M28S carries the 9N510 warhead, which dispenses 180 individual incendiary elements composed of a magnesium alloy shell filled with a thermite-like incendiary composition. (ARES)
Analyst Note:
122 mm ‘Grad’ rockets can be fired from a variety of launchers and even in improvised ways. The most common is the BM-21 launcher and its later derivatives, but many other portable or vehicle-mounted launchers have been used around the world. Craft-produced examples—ranging from simple rails to more complex designs comparable to factory made launchers—are also common. In some cases, Grad rockets are even fired whilst supported by a crude arrangement of logs, bricks, or rocks. (ARES)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
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)
2 Analyst Notes:
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)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
Whereas many cartridges are of the 'fixed' type—with the propellant charge contained entirely within the cartridge, and the cartridge case crimped around the projectile—the OF-540 artillery gun projectile is a type of 'semi-fixed' ammunition. A round of semi-fixed ammunition is separated into two groups of components: the projectile and fuze; and the cartridge case, primer, and one or more propellant charges. These two component groups are typically combined at the time of loading the gun, or shortly beforehand. The majority of ammunition fired by artillery systems is either semi-fixed or 'separate loading' (see Glossary). (ARES)
Analyst Note:
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)
Analyst Note:
This image shows a 9M27K2 cargo rocket as well as several partially ejected PTM-1 anti-vehicle landmines. This 9M27K variant is fitted with the 9N128K2 payload section which carries and dispenses 24 PTM-1 mines. Other variants carry different mines or submunitions. (ARES)
Analyst Note:
In the Ukraine conflict, several groups have offered a service whereby financial supporters can have a message of their choice marked on a munition. Such messages are often references to memes or popular media. The middle artillery projectile shown here is marked with “omae wa mou shindeiru”—an English transliteration of the Japanese phrase お前はもう死んでいる (“you are already dead”), which appears in the popular Fist of the North Star manga and anime series. (ARES)
