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.
This image shows the damaged aerofoil group, or ‘tail kit’, found with a Chameleon 3 bomb guidance kit. The exact model of aerofoil group is unknown, but in US service similar component groups are given a designation in the ‘MXU-xxx’ range, and are interchangeable with different variants of the Paveway bomb guidance kit (within bomb weight classes). (ARES).
Although Human Rights Watch reported that they found manufacturing markings on a guidance fin assembly indicating that this MXU-series aerofoil group was paired with a Paveway III guidance kit, this cannot be determined by this wing remnant from the aerofoil group alone. (ARES)
This image shows fragments of a BLU-109C/B 2,000-pound penetrator bomb. The remnant with visible threads is part of the aft closure ring attached to the base of the bomb. This features nine vent holes as an ‘insensitive munition’ (IM) safety feature. Three of the threaded vent holes are visible on this fragment. (ARES)
This image shows a remnant of the tail actuator subsystem of a Joint Direct Attack Munition (JDAM) bomb guidance kit. The size of this JDAM kit indicates that it is one of the kits compatible with 2,000-pound-class bombs, either the MK-84 or BLU-109. (ARES)
This image shows a variety of small air-delivered munitions that have been developed specifically for deployment via UAV. Some of these appear to be original designs, whilst others have been made by modifying existing munitions. This entry reflects those munitions outlined with the red box, but all of the munitions are generally of similar in size and format, and all have tailfin assemblies intended to orient the munition as it falls, just like more traditional air-delivered bombs. (ARES)
The munition in this image has been integrated into a commercial off-the-shelf (COTS) small UAV. This UAV (‘drone’) adds powered and guided delivery and converts the munition into a guided missile—regardless of the original, intended delivery method. (ARES)
The warhead of the OWA UAV indicated in this image cannot be positively identified from this photograph alone. It appears to be the warhead section of either an OG-9 series or OG-15 series high explosive fragmentation (HE-FRAG) projectile, with a GO-2 or similar impact fuze fitted in the nose. (ARES)
This image shows four PFM-1 series anti-personnel landmines retained by a release mechanism to enable deployment via UAV. Ordinarily, PFM-1 series and other ‘scatterable mines’ are deployed via carrier munitions or dedicated mine-dispensing devices. In Ukraine and other conflicts, these mines have often been removed from their original carrier munitions in order that they may be delivered via UAV. (ARES)
This image shows the nosecone from an Israeli SPICE 250 air-delivered bomb. Whilst generally similar in appearance to the nosecone of the GBU-39, the SPICE 250 nosecone is longer and narrower. (ARES)
This image shows a Mikholit glide bomb, with its warhead removed (green cylinder on the left side of the box). The fins that spring outward when deploye have been taped down. This Mikholit was reportedly recovered by the Israeli Defense Forces (IDF) from Hamas, who had captured the bomb after it failed to function when originally deployed by the IDF. (ARES)
This image shows two Mikholit air-delivered bombs (‘glide bombs’), and four Mikholit warheads. There are at least two different variants of warheads available for the Mikholit glide bomb. The green cylinder on the left is a blast (high explosive) warhead, whilst the other three warheads are shaped charge warheads which incorporate additional fragmentation. Blast warheads of this type have also been seen with red markings, while the shaped charge warheads have been seen with yellow markings. (ARES)
This image shows various remnants from GBU-39 air-delivered bombs, including two fuze wells. Each GBU-39 has only a single fuze well, indicating that this picture shows the remnants of at least two different GBU-39 bombs. (ARES)
This image and the related entries show fragments of an AGM-84 Standoff Land Attack Missile-Expanded Response (SLAM-ER) series missile. AGM-84 SLAM-ER missiles are AGM-84E Standoff Land Attack Missiles (SLAM) that incorporate certain upgrades, including wings to increase the missile's range. The AGM-84 series include the anti-ship ‘Harpoon’ variants, from which the SLAM and SLAM-ER series are derived. As a result, many remnants will be similar or identical between variants. The wing remnant here is diagnostic, however. (ARES)
This image shows several GBU-53/B bombs photographed from above while on a munitions transport cart. GBU-53/B bombs are transported and loaded onto the aircraft with the wing assembly on the bottom. When the GBU-53/B is released from the aircraft, the bomb rotates, with the wing assembly side orienting as the top as the bomb glides to its target. (ARES)
This image shows a strake from a Joint Direct Attack Munition (JDAM) guidance kit (KMU-557/558) as fitted to 2,000-pound BLU-109-series penetrator bombs. (ARES)
This image shows two MAM-L guided air-delivered bombs affixed to the wing of a Bayraktar TB2 drone. The MAM-L and TB2 are both produced in Türkiye by Roketsan and Baykar respectively. The MAM-L can have one of three different warheads: blast fragmentation, anti-tank, or thermobaric. The warhead section of each MAM-L in this image has “YIPE/BF” visible. ‘YIPE’ is the abbreviation of the warhead type in Turkish: Yüksek Infilaklı Parçacık Etkili (‘high explosive fragmentation’, in English). The ‘BF’ also indicates that these MAM-L munitions are of the blast-fragmentation variant. The warhead of a MAM-L cannot be determined from an external assessment without viewing markings such as these (or a clear view of the data plate, which can be seen on the aft portion of the MAM-L). (ARES)
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)
