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.
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)
