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.
This image shows several remnants of a MAM-L bomb that are typically found after functioning. The actuated fins, as well as the fixed fins, are visible, along with various components of the control section that actuate the fins. The actuated fins attach to the control section, at the rear of the bomb, while the fixed fins attach to the middle of the bomb body. (ARES)
This image shows a relatively intact Shahed-131 one-way-attack (OWA) UAV with various components highlighted, including the GPS antenna array (light blue), fuselage (light purple), engine (yellow), wing stabiliser (orange), and nose cone (cyan, inside the red box). The nose cone attaches to the front of the fuselage and covers the warhead. (ARES)
Two R-77 air-to-air missiles (NATO reporting name: AA-12 Adder) are carried in this photograph by a Russian Aerospace Forces Sukhoi Su-35 fighter aircraft. Key markings, including the aircraft’s bort number (a coloured numeral that acts as a unit or base identifier), have been digitally obscured. (ARES)
This image shows the functioned rocket motor of an Israeli Carpet rocket. The Carpet uses a fuel-air explosive (FAE) warhead which is designed to function mines and improvised explosive devices (IEDs), clearing a target area for the advance of friendly forces. These rockets are fired from the Carpet rocket launcher, which is loaded with up to 20 rockets and can be fitted to a variety of vehicles. (ARES)
The Armement Air-Sol Modulaire (AASM; ‘Modular Air-to-Ground Armament’) family of French bolt-on guidance kits are fitted to air-delivered bombs of various sizes in a similar fashion to American JDAM kits. In some marketing materials, the acronym HAMMER is used, standing for ‘Highly Agile Modular Munition Extended Range’. This refers, in part, to the rocket boosters fitted to munitions in the family to extend their effective range. (ARES)
In this photo, a Ukrainian Sukhoi Su-25 ground-attack aircraft from the 299th Tactical Aviation Brigade, with the bort number ‘Blue 28’, is seen carrying an AASM-250 guided air-delivered bomb under its left wing. Available imagery shows that the AASM-250 has also been fitted to Mikoyan MiG-29 fighter aircraft, and can likely be carried by the Sukhoi Su-27 as well. (ARES)
This image shows an Israeli Air Force F-16 carrying four Rampage air-to-ground missiles. The Rampage is a 580 kg (1,278 lb) missile with GPS and INS guidance. It carries a multi-purpose warhead that is designed for engaging a range of targets in the open as well as offering some degree of penetration. (ARES)
This image shows a North Korean 120 mm high explosive (HE) mortar projectile next to an Iranian 120 mm HE mortar projectile. Despite both being the same calibre, the overall shapes and dimensions of the two projectiles are noticeably different. Factors such as payload weight and range can be affected significantly by projectile shape. (ARES)
The ZAB-250-200 (ЗАБ-250-200) unguided air-delivered bomb is loaded with 48 kg of a napalm-like thickened incendiary mixture, 8 kg of cotton scraps soaked in kerosene (paraffin), and 4 kg of pyrotechnic composition to aid with ignition. (ARES)
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)
The Stunner surface-to-air missile fired by the David’s Sling air defence system is a two-stage interceptor, meaning that the munition contains two separate rocket motors for launch and propulsion. The first stage, or launch motor, detaches from the munition after a short time, before the second stage, or flight motor, ignites. The second stage motor, visible here, was found relatively intact. (ARES)
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)
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)
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)
The RAFAEL Advanced Defense Systems SPICE 1000 guidance kit is fitted to MK 83-series 1,000-pound unguided air-delivered bombs to convert them to precision guided munitions. Like the JDAM-ER, it has a deployable wings to provide a ‘gliding’ attack trajectory. (ARES)
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)
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)
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)
This image shows an Israeli Air Force F-16C fighter aircraft from 101 Squadron carrying a MK 84-series 2,000-pound-class air-delivered bomb fitted with a SPICE 2000 ‘bolt-on’ guidance kit. (ARES)
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)
The AGM-179 Joint Air-to-Ground Missile (JAGM) is derived from the AGM-114 Hellfire series of air-to-surface missiles—and thus shares physical characteristics in terms of general construction, including rear fin placement. The marked weight of 52.0 kg (115 lbs) is generally believed to be an indicator that the rocket motor is from a JAGM; however, remnants marked with this weight have been observed from several years before the JAGM was initially fielded. (ARES)
In this image, four AGM-114 Hellfire-series missiles can be seen fitted to an M299-series missile launcher, itself attached to the stub wings of this Israeli AH-64 Apache helicopter. In theory, the Apache could be armed with up to sixteen Hellfire missiles, but fewer are carried in practice to allow for other weapons and sensor payloads (ARES).
‘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)
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)
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)
