Internal Iranian and Russian documents with interesting information regarding cooperation between the two countries in the production of UAVs have been leaked online.

The published documents contain data on:

- Shahed-238 (M237) kamikaze jet UAV with satellite guidance.
- The same Shahed-238, but with a thermal imaging optical-electronic guidance station (MC 236);
- Reconnaissance and kamikaze UAVs Shahed-107B and Shahed-107C;
- Kamikaze UAV Shahed-101P.

In addition, the leaked data contains information about the places and methods of production of UAVs, concluded contracts, channels of their supply to Russia, transportation methods, etc. which is a colossal gap in information security.

The documents do not directly mention the type of product being manufactured. Instead, UAVs are listed in documents under a special code as "Dolphin 632 type motor boat."

According to the papers, by 2022, Russia intended to produce 6,000 Iranian UAVs under license at its facilities for 2.5 years.

The total price of the production contract, including the transfer of technologies, equipment, 6,000 sets of UAVs, software, is 108.5 billion rubles ($1.75 billion).

During the inspection of the wreckage of Iranian-made Shahed-238 kamikaze UAV, Ukraine discovered turbojet engine of the Czech company PBS Velká Bíteš type TJ150, providing Shahed-238 a speed of about 520 km/h during the active phase of the flight.
