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.
Fins that can be adjusted during flight to allow the alteration of a munition’s trajectory, or those that can be adjusted to reduce the size of a munition during transport and employment.
This image shows a remnant of a control fin from a Paveway III bomb guidance kit that is compatible with 2,000-pound-class air-delivered bombs. In U.S. service, this combination receives designations in the GBU-24 series. Based off this remnant alone, it cannot be determined which model of air-delivered bomb was paired with this particular guidance kit. (ARES)
This image shows a GBU-12 series guided bomb being loaded onto a F-35B belonging to Marine Fighter Attack Squadron 211. Two of the control fins have not yet been installed in the Paveway’s guidance control section. (ARES)
This image shows a remnant of the control fin of a GBU-24 (as seen partially marked), the designation for the combination of a Paveway III guidance kit paired with a 2,000-pound-class air-delivered bomb. This remnant is not enough to determine which model of bomb the kit was originally paired with. (ARES)
This image shows a BLU-111 500-pound-class bomb paired with a Paveway II guidance kit, and an MXU-650 series airfoil group, or tail kit. This combination is designated the GBU-12 series in U.S. service. (ARES)
This image shows various remnants of an air-delivered bomb and a Paveway guidance kit. The blue pen provides a scale indicator, which is necessary to identify which variant of aerofoil (‘airfoil’) group the tail fins belonged to. In this case, they are most likely from an MXU-650-series airfoil group, which are paired with MK-82 500-pound-class bombs. (ARES)
This still taken from a video released by Iranian state media, shows a one-way-attack UAV purportedly manufactured by Israeli forces operating inside Iran. This UAV was found alongside manufacturing equipment, and additional UAV components, strongly suggesting that it was manufactured or assembled inside Iranian borders. (ARES)
This image shows a remnant of the guidance control unit from a Paveway- or Lizard-series bomb guidance kit. The guidance control fins are marked “FOR USE ON MK82” indicating that this guidance control unit was paired with a MK 82-series 500-pound-class bomb. (ARES)
This image shows a variety of remnants from an Israeli SPICE 250 guided bomb. One of the bomb’s four control fins is visible at the bottom-left of the image. (ARES)
This image shows a remnant of the control section of the Arrow 2 ‘kill vehicle’, including the control fins. The blast-fragmentation warhead is located in the front section of the kill vehicle, forward of the control section, and is absent here due to the functioned state of the munition. (ARES)
This image shows a Mikholit that was ejected from the weapons pod of an Israeli Hermes 900 drone that was downed in Iran. This Hermes 900 drone had two weapons pod, each capable of carrying 4 Mikholit bombs. (ARES)
The source for this entry reports that these remnants were left behind after the missiles were “recycled“. Explosive remnants of war (ERW) are often recycled for the value of their scrap metal, or ‘harvested’ by militant groups for the explosive material. These recycling attempts may result in the ERW exploding, potentially killing or injuring people. (ARES)
This image shows the guidance control unit from an Israeli 'Chameleon 3’ bomb guidance kit. This kit appears similar to those in the Israeli Lizard series of guidance kits, which are derived from the American-designed Paveway kit series. (ARES).
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 the remnants of a SkyStriker one-way attack UAV, manufactured by Elbit Systems of Israel. The SkyStriker can be fitted with various warhead options, including dual-purpose warheads weighing 5 or 10 kilograms. While it appears that a reconstruction was attempted with the remnants, the placement of the various components does not accurately represent an intact SkyStriker. (ARES)
This image shows the flare from a Terminal High Altitude Area Defense (THAAD) system's ‘Talon’ kinetic interceptor missile. The flare is located at the aft end of the missile's booster engine. The ‘petals’ of the flare are initially flush, and are actuated into the deployed position, seen here, as part of the missile‘s functioning. (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)
