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.
Unmanned aerial vehicles which may be remotely piloted, or fly autonomously or semi-autonomously. UAVs which feature integrated munitions or warheads are often referred to as “suicide drones” or “one-way-attack (OWA) munitions”, and effectively function as guided missiles. This attribute is tagged in the OSMP to align with vernacular usage.
This photo shows some of the lithium-ion power banks found within a Gerbera UAV. These are used to power the onboard avionics, control surfaces, communications hardware, camera, and other components. The quantity and type of batteries fitted to the Gerbera will often vary based on the role for which the UAV has been configured—one-way attack (OWA; i.e., a ‘sacrificial’ munition), reconnaissance, signal relay, or decoy—and which specific hardware has been installed to effect this mission.

This photo shows the fuel bladder of a Gerbera UAV, which still contains some fuel. It is likely that a bladder is used—rather than a rigid tank—to save on both weight and cost. Some variants of the Gerbera have been observed to be fitted with a second bladder in the forward section of the fuselage, serving to extend the UAV’s range. (ARES)
The DLE60 two-stroke petrol (gasoline) engine pictured here is the standard engine found on Gerbera UAVs. It is produced by the Chinese company Mile Haoxiang Technology Co., Ltd. and marketed specifically for use in UAVs. Although the Gerbera is manufactured in Russia, the engine and many other key components continue to be supplied from Chinese sources. (ARES)
This image shows a Controlled Reception Pattern Antennas (CRPA) unit installed on a Gerbera-series UAV. CRPAs are specialised antenna arrays that help protect GPS receivers from interference, spoofing, and jamming. This particular model, featuring four antennas, was first observed on the Shahed-136 UAV and has since been routinely seen fitted to Gerbera-series UAVs. An alternative array, with six antenna elements, has also been observed, reflecting the varied and ever-evolving state of electronic warfare in Ukraine. (ARES)
A Gerbera-series UAV is pictured here being carried by just two Ukrainian soldiers. This highlights the Gerbera’s lightweight design—the airframe is mostly constructed from Styrofoam and wood, which saves on both weight and cost. This particular example does not bear signs of significant damage, suggesting that it either malfunctioned or was brought down by EW and crashed. (ARES)
This image shows an A40 Pro camera, manufactured by the Chinese company Viewpro UAV and design specifically for use in UAVs. The black box to the right of the camera is the control box which manages video output, camera control, and power. The manufacturer claims this model has a 40× optical zoom, AI detection and tracking, and 3-axis gyro-stabilisation. The company further claims that it can customise the onboard AI recognition based on “target characteristics” provided by the client. Numerous Gerberas fitted with this model of camera are known to have been recovered by Ukrainian forces, although it is by no means the only camera model in use. (ARES)
This image shows the back surface of a wireless communications module contained within a downed Gerbera UAV. Although labeled as an HX-50 model designed for fixed locations, Ukrainian military analysis indicates this is an XK-F358 mesh-network module more suitable for use in UAVs. See OSMP1646 for further details. (ARES)
This image shows the front and interior surfaces of a wireless communications module recovered from a downed Gerbera UAV. Although labelled as an HX-50 industrial wireless modem (compatible with WiFi and 5G/4G networks and designed for fixed locations), analysis by Ukrainian military sources indicates that this component is, in fact, an XK-F358 mesh-network module which offers significantly more capabilities. Manufactured and sold by Shenzhen Xingkai Technology Co., Ltd., these modules are designed for, amongst other things, use in robots and unmanned vehicles. Gerbera UAVs have been found operating on a wide variety of frequencies and networks, and this type of module is well-suited to this use. (ARES)
Pictured is a navigation/GPS module recovered from a downed Gerbera UAV. This particular model is used with the 4-antenna CRPA module seen in OSMP1648. The four RX ports on the bottom are normally directly connected to the CRPA (antenna) module, with other connections made to the UAV’s flight controller and power sources. Some Gerberas have been recovered with CRPA modules bearing a different number of antennas; different navigation modules have been observed on these. (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)
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)
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 an AR731-4000 Wankel-type engine produced by UAV Engines Ltd. of the United Kingdom, used in an Israeli Harop munition. Variants of the Harop used in the 2020 Nagorno-Karabakh War featured a similar Wankel engine, but were marked to indicate a different manufacturer and model name: “MBT ENGINE” and “H2251-5100-503”, respectively. (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 three different warheads developed by Russia for the Shahed-136/Geran-2 one-way attack (OWA) unmanned aerial vehicle (UAV), each of which differ from the original warhead designed by Iran for the Shahed-136. Left: A thermobaric explosive warhead; Middle: TBBCh-50M, a thermobaric explosive warhead; Right: OFZBCh-50, a high explosive warhead with an incendiary effect. Each of these warheads is also fitted with a fragmentation liner to increase the fragmentation effect generated when the warhead detonates. Some of the fragmentation liners may contain zirconium, a metal which is ignited when the warhead detonates, providing an additional incendiary effect. (ARES)
This image shows the copper cone of the shaped charge located at the front of the warhead fitted to a Shahed-131. The Ukrainian armed forces have recorded that the cone measures 111 mm in diameter and 162 mm in depth. The warhead is lined with cubic pre-formed fragments of 7 mm in diameter. The explosive content of the warhead is estimated to be between 10 and 15 kg. (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)
These images show a damaged Serat-01 engine which powers the Shahed-131 drone after its rocket-assisted launch. The Serat-01 is a copy of the MDR 208 engine, and is noticeably smaller than the MD550 which powers the larger Shahed-136. (ARES)
This image shows the BSF-50, one of several warheads developed by Russia for the Shahed-136/Geran-2 to replace the original Shahed-136 warhead designed by Iran. The BSF-50 is a high explosive warhead with a fragmentation effect. (ARES)
Depicted here is the MD-550 motor of a Shahed-136/Geran-2. This image was presented by Ukrainian President Zelenskyy as a fragment of the drone that reportedly hit the Chernobyl Nuclear Power Plant’s New Safe Confinement shelter. (ARES)
This image shows one of several possible warhead variants that can be carried by the Shahed-136/Geran-2 one-way attack (OWA) UAV. The Shahed-136/Geran-2 (and the smaller Shahed-131/Geran-1) has been documented carrying shaped-charge warheads, penetrator warheads, and multi-function warheads. Due to the various warheads that can be carried by a Shahed/Geran drone, the functional use cannot be determined without the warhead being visible. In this case, the munition was fitted with a TBBCh-50M warhead that contains a thermobaric explosive composition with an additional fragmentation effect. (ARES)
Shahed-131/Geran-1 and Shahed-136/Geran-2 one-way-attack (OWA) UAVs can be fitted with on of a variety of warheads with different functional uses. The specific type carried by each UAV cannot be determined unless the munition has been damaged in such a way as to reveal the warhead, such as in this case. This image shows the cone of the shaped charge, indicating that this Shahed-1/Geran-1 carries a warhead with a penetrating or anti-armour effect. This warhead has been documented with 18 additional liners for enhanced anti-armour effect, and in some cases has been fitted with fragmentation liners for an enhanced anti-personnel effect. (ARES)
Honeycomb-like internal structures are often used in aerospace applications to provide rigidity with reduced weight, and are sometimes constructed using materials which reduce radar cross-section by absorbing or scattering electromagnetic waves. (ARES)
