Shahed-131 series
An Iranian-designed powered munition of the type often known as a one-way-attack (OWA) unmanned aerial vehicle (UAV), or drone, with an estimated range of 700–900 km. It is 2.6 metres in length, has a 2.2-metre wingspan, and is capable of carrying a range of warheads weighing between 10-15 kg. It uses both GNSS and inertial navigation for guidance and typically acts as a pseudo-missile, flying towards pre-programmed coordinates before exploding on impact. It is used extensively in the Middle East and Ukraine, with Russia producing a copy of the Iranian Shahed-131 known as the Geran-1.Smaller than the Shahed-136, the 131 is primarily identifiable by its vertical wing stabilisers, which extend above the delta-wing assembly, but not below it.

Analyst Note:
This image shows the copper cone of the shaped charge located at the front of the warhead. Armed Forces Ukraine have documented that the cone measures 111 mm in diameter, and 162mm in depth. The warhead is lined with cubic fragments that are 7mm. The explosive content of the warhead is estimated between 10 to 15 kg. (ARES)
Analyst Note:
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)
Analyst Note:
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)
Analyst Note:
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)
