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.
Munitions that are delivered from above the surface of the earth, typically from an aerial vehicle, and designed to strike surface-based targets — whether on land or at sea.
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 Blue Sparrow-series air-launched ballistic missile is being carried by an F-15C fighter aircraft from 106 Squadron Israeli Air Force. The missile is marked with the logos of three organisations involved in its development—the U.S. Missile Defense Agency, the Directorate of Defence Research & Development, and the Israel Missile Defense Organization—and the Blue Sparrow programme logo of the manufacturer (Rafael Advanced Defense Systems). The booster section also features bright-orange fins and markings consistent with its use as a target missile, here modified to accept a high explosive warhead. (ARES)
The Blue Sparrow is one of a series of three of air-launched missiles originally designed by Rafael as targets to test ballistic missile defence systems. Blue Sparrow missiles can be fitted with either inert or high explosive (HE) warheads. The recovery of Sparrow-series boosters following a reported Israeli strike on an Iranian air-defence system could suggest that a derivative variant of the Blue Sparrow missile was further developed for engaging surface targets.

Labels on munition remnants can provide a host of useful data, including the model designation (in this case, “GBU-39/B”), part number (PN; (“70P998100-1003”), National Stock Number (NSN; “1325-01-526-8728”), serial number (SN; illegible), and Department of Defense Identification Code (DODIC; “EC53”). These codes, and others like them, can often be searched for in databases or provided to technical specialists for further interpretation. (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 BLU-117 air-delivered bomb is nearly identical in format to the more common MK 84, but uses the PBXN-109 explosive filler which is more insensitive than the typical explosive compositions found in MK 80-series bombs. The BLU-117 is also coated with a grey, thermally resistant paint, and marked with three yellow bands (as opposed to the green paint with two yellow bands found on standard MK 80-series bombs). These changes were requested by the U.S. Navy for safer storage of these munitions aboard ships. (ARES)
The visible component is part of a Joint Direct Attack Munition (JDAM) guidance kit, an accessory package that is fitted to unguided air-delivered bombs to convert them to precision guided munitions. Specifically, this image shows a control fin from the tail assembly. Whilst the JDAM kit would not constitute a munition in its own right, this remnant is included in the OSMP as contextual information strongly suggests it formed part of a complete munition that functioned. (ARES)
The JDAM-ER in this photograph is affixed to an unusual pylon thought to be of Ukrainian design, which allows the Western munition to be carried by the Soviet-designed Mikoyan MiG-29 and Sukhoi Su-27 fighter aircraft in service with the Ukrainian Air Force (a MiG-29 is pictured here). (ARES)
This is an image released by the Israeli Defense Forces that shows an F-15I of 69 Squadron Israeli Air Force preparing to take part in a high-profile airstrike on 27 September 2024, in which the leader of Hezbollah, Hassan Nasrallah, was killed.
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)
Contextual information, including an assessment of the crater which appears to be linked to this munition remnant, suggests that a 2,000-pound-class bomb fitted with a SPICE 2000 guidance kit was used in this airstrike. (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)
In this image, an F-15C fighter aircraft from 106 Squadron Israeli Air Force is seen carrying two MK 84-series 2,000-pound-class air-delivered bombs fitted with Joint Direct Attack Munition (JDAM) ‘bolt-on’ guidance kits. In U.S. service, this combination is known as the GBU-31. (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).
The Joint Direct Attack Munition – Extended Range (JDAM-ER) marries the JDAM guidance kit to a ‘glide bomb’ wing kit developed by the Australian Defence Force, offering a munition with at least three times the range of a standard GBU-38 500-pound-class guided aerial bomb. (ARES)
In this image, two GBU-39 Small Diameter Bombs are attached to a BRU-61/A bomb rack. The Ukrainian Air Force adapted this American-designed bomb rack to fit their Soviet-designed Mikoyan MiG-29 fighter aircraft. The BRU-61/A can carry up to four GBU-39 air-delivered bombs. (ARES)
This image shows a distinctively shaped component of MBDA’s ‘Diamond Back’ joined tandem wing assembly as fitted to the GBU-39 Small Diameter Bomb (SDB). (ARES)
The SPICE family of munitions, manufactured by Israeli aerospace and defence company Rafael, includes two models which use ‘bolt-on’ guidance kits. The SPICE 1000 and SPICE 2000 models convert 1,000- and 2,000-pound unguided aerial bombs, respectively, to precision guided munitions. (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)
