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 a russian air-delivered bomb fitted with a UMPK guidance kit. Not enough of the bomb is visible to positively identify the model, but it is most likely an OFAB-250-270 based on what can be seen of the tail section. (ARES)
The munition indicated is a one-way-attack (OWA) UAV fitted with a PG-7-series high explosive anti-tank (HEAT) warhead. Not enough of the warhead is visible to provide a positive ID on which model of PG-7-series projectile it was harvested from. (ARES)
The AGM-154 Joint Standoff Weapon (JSOW) is a guided air-delivered ‘glide bomb’ that allows for long-range strikes using an unpowered munition. The AGM-154C and AGM-154C-1 variants (a remnant of the latter pictured here) carry a Bomb Royal Ordnance Augmented Charge (BROACH) multi-stage warhead which uses a WDU-44 shaped-charge warhead as its first stage, to help penetrate hardened targets, whilst the WDU-45 second stage comprises a conventional high explosive penetrator warhead (also called a ‘follow-through’ warhead). The AGM-154C-1 is described by the U.S. Navy as their “first air-to-ground Network-Enabled Weapon (NEW) capable of attacking stationary land and moving maritime targets. It includes GPS/INS guidance, terminal IR seeker and a Link 16 weapon data link. Integration of the Link-16 weapon data link and updated seeker software algorithms provide a capability against at-sea moving/relocatable targets.” (ARES)
Markings on the forward section of this small, air-delivered bomb suggest that the designation is ‘BK-3OF’ (“БК-3ОФ”). The physical features of the munition suggest that it is laser-guided and likely carries a high explosive fragmentation (HE-FRAG) payload. This image shows the only known example, which was allegedly captured by Russian forces in conjunction with a Ukrainian UAV. (ARES)
This Russian air-delivered cluster bomb is marked with a threatening message directed at the French people: «Français! Changer la politique du président dans le pays, sinon ces bombes vont changer le lieu d'atterrissage!» (“French people! Change the president’s policy in the country, otherwise these bombs will change their landing site!”). (ARES)
This image shows a Hydra-70 rocket fitted with an Advanced Precision Kill Weapon System (APKWS) guidance kit, converting it into a guided missile. In this case, the missile features an M151 high explosive (HE) warhead fitted with either an M427 or M423 point-detonating (PD) fuze. The rocket motor model cannot be determined from this source alone, but it is most likely to be a MK 66-series motor. The launcher appears to be a LAND-LGR4 model produced by Arnold Defense. (ARES)
This image shows a ‘120mm TB’ air-delivered bomb that has been adapted from a 120 mm mortar projectile. It is claimed by the manufacturer that this thermobaric munition offers improved fragmentation and blast effects when compared with standard (high explosive) 120 mm mortar projectiles. The “with special FUZE” marking refers to the use of the UT M18 impact fuze. Note that this munition cannot be fired from a mortar, despite the munition body showing features consistent with this use (e.g., gas-check bands). Instead of a standard mortar projectile tailboom which would contain an ignition cartridge and be perforated by flash holes, this munition is fitted with a simplified, plastic tailfin assembly that is designed to stabilise the munition as it falls after being released by a UAV. (ARES)
This image shows the rear section of a Hydra-70 rocket. The Hydra-70 uses the MK 66 series of rocket motors, visible here, but can be fitted with at least 11 different warheads. They can also be fitted with the Advanced Precision Kill Weapon System (APKWS) ‘bolt-on’ guidance kit, converting an unguided rocket into a guided missile. From the available imagery, it is not clear with which warhead or guidance section this munition may have been fitted. (ARES)
This image shows the venturi and tailfin assembly from a 57 mm S-5 series rocket. The S-5 series of rockets are commonly used around the world in a variety of roles, including air-to-surface and surface-to-surface. Unfortunately, from this image alone the specific model and country of origin cannot be determined. (ARES)
This image shows remnants of a Russian Kh-101 air-launched cruise missile. The remnant on the right is the rearmost tail section of the missile. (ARES)
This image shows a remnant of the TRDD-50A(M) (ТРДД-50А(M)) turbojet engine, which powers Kh-101 and Kh-59M missiles. Other models of Russian cruise missiles are known to use other variants of the TRDD-50. (ARES)
This image shows the three lenses that form the new version of the Kh-101 Digital Scene Matching Area Correlator (DSMAC) system. (The older version only had a single lens.) DSMAC systems take digital images of the ground as the missile passes overhead, and then compare those images to pre-captured images stored in the onboard memory. The DSMAC corrects the flight path as needed based on differences between the two sets of images. (ARES)
This image shows the second warhead present in some variants of the Kh-101 cruise missile. The inclusion of this additional warhead requires a smaller fuel tank in the missile, offering increased explosive weight in exchange for a reduced maximum range. (ARES)
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 markings on an SUU-30H/B dispenser which comprises part of a CBU-52B/B Cluster Bomb Unit, including a National Stock Number (“NSN 1325 00 477 2053-E800”), design reference (“AF DRAWING NO: 716514-10”), total explosive weight of the submunitions (“CYCLOTOL: 133 LBS:”), lot number (“LOT NO: MA-77G246-002”), and serial number (“SERIAL NO: EE-97391”). This lot number indicates that this CBU-52B/B was manufactured at the Milan Army Ammunition Plant in the U.S. in July 1977. (ARES)
This image shows part of an SUU-30H/B dispenser (cargo munition) that comprises part of the CBU-52B/B ‘Cluster Bomb Unit’. A CBU-52B/B comprises a SUU-30H/B dispenser that is loaded with 217 BLU-61A/B anti-personnel submunitions. (ARES)
This image shows one of two tail fin sections that are attached to an SUU-30H/B air-delivered dispenser (cargo munition). Similar tail fins are used in other variants of the SUU-30 series dispensers. The SUU-30H/B can be used in various ‘Cluster Bomb Units’ including variants of the CBU-52, CBU-58, and CBU-71 munitions. (ARES)
This image shows a remnant of an SUU-30H/B air-delivered dispenser (cargo munition), that comprised a CBU-58A/B ‘Cluster Bomb Unit’ (CBU). The CBU-58A/B carries 650 BLU-63A/B anti-personnel submunitions, that have a total explosive weight of 163 lbs (~74 kg) of COMP B explosive; this is reflected in the visible markings. (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 a control actuator shaft from a Paveway guidance kit control section, found after a strike in Yemen in 2015. Markings giving the CAGE code for Raytheon (“96214”) and the part number (“2870627-2”) are both visible. The complete remnant can be seen in related entry 1559. (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 remnants of an MXU-series airfoil group, or tail section, that is paired with Paveway-series bomb guidance kits. The remnant on the right is one of two retractor mechanisms that are present inside the MXU-series airfoil group. (ARES)
This image shows a close up view of an actuator assembly from an AGM-114 ‘Hellfire’ series missile. This assembly is what actuates the control fins, and the attachment point for one of the control fins is visible at the bottom right of the image. This assembly belongs to the control section, which is the rearmost section of the missile. (ARES)
This image shows the bottom of an MS 3314 suspension lug, which is installed on the MK 81 250-pound-class, MK 82 500-pound-class, and MK 83 1,000-pound-class air-delivered bombs. The remnants of the guidance kit in the related entry indicate that, in this case, the lug was fitted to a MK 83 1,000-pound-class bomb. “A4447” is the CAGE code for the manufacturer of the suspension lug, RWM Italia. (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 image shows some of the markings on a MK 84 2000-pound-class air-delivered bomb, including model designation (“BOMB MK 84 MOD 4”), weight class (“2000 LBS”), part number (“PART NO 30…03 923AS105”), and production lot (“LOT NO GDT 17 …00…”). Many countries produce MK 80-series bombs, so markings such as lot numbers can determine the country of production. “GDT 17” in the lot number indicates that this munition was produced by General Dynamics Ordnance and Tactical Systems, an American company, in 2017. The Israeli Air Force announced they carried out the specific strike associated with this image, which indicates that this specific bomb was transferred to the Israeli Air Force. (ARES)
This image shows a remnant of a JDAM tail kit that was paired with a MK 84 2,000-pound-class air-delivered bomb. The CAGE code (“OUVG2”) for Aeroantenna Technology, an American manufacturer of GPS components for guidance systems, is visible on the wiring. (ARES)
This image shows the remnants of an unknown Israeli munition that was used in a strike on Nasser hospital. Reporting on these strikes often refers to this munition as a ‘drone’. The turbojet engine, along with possible wing remnants, indicate that this could be a one-way-attack (OWA) UAV or ‘loitering munition’ missile, consistent with reporting. This same model of munition has been used multiple times in strikes in Gaza, as well as Lebanon and Syria. There is no publicly acknowledged Israeli munition that closely fits these remnants. Entries 1384, 1385, 1386, and 1389 capture other incidents in which this munition was used. (ARES)
This image shows a Russian spherical submunition of unknown designation. Whilst this specific example was delivered by a cluster munition variant of the Kh-59MK2 missile, this submunition is known to also be delivered by variants of the Kh-69. A similar, but different, spherical submunition is delivered by some variants of the Kh-101. (ARES)
This image shows the remnants of an unknown Israeli munition that was used in a strike that hit the Nasser hospital in Gaza. The turbojet engine, along with possible wing remnants indicate that this could be a one-way attack UAV or ‘loitering munition’, consistent with some reporting on the strikes. This same model of munition has been used in multiple strikes in Gaza, as well as in Lebanon and Syria. There is no publicly disclosed Israeli munition that neatly matches these remnants. OSMP entries 1384, 1385, 1386, and 1389 show other incidents in which this munition appears to have been used. (ARES)
This image shows part of a Russian Kh-59MK2 missile that is fitted with a cluster munition warhead. Some of the grey spherical submunitions are visible, both inside and outside the warhead. (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)
