Several explosions were reported in the city of Kaspiysk, Dagestan, early on December 1, near the Dagdizel plant—a key Russian defense enterprise producing torpedoes and diesel engines for the Russian Navy.
According to ASTRA, local residents reported loud blasts and damage to residential buildings, including shattered windows and vehicles struck by debris.
The explosions occurred near the premises of the Dagdizel facility, though no official confirmation has been made regarding whether the plant was directly targeted.

The head of the Republic of Dagestan, Sergey Melikov, acknowledged the incident and stated that a drone attack was “successfully repelled,” without providing further details. He added that local authorities are responding to the situation and reiterated that publishing information about strikes or military locations in the region is prohibited.
Founded in 1932, the Dagdizel plant — also known as Plant No. 182 — remains one of the largest military-industrial enterprises in Dagestan.
It specializes in the production of naval weaponry, including torpedoes, diesel engines, pumps, and auxiliary systems for the Russian Navy. During the Soviet era, the factory was among the USSR’s leading torpedo manufacturers.
Today, Dagdizel operates under the umbrella of the state-owned “Marine Underwater Weapons — Gidropribor” corporation.
The facility remains a core part of Russia’s naval armament production chain. In 2018, Russian media reported that the plant had secured a $72 million contract with the Russian Ministry of Defense for the delivery of 73 UET-1 torpedoes.
Some torpedoes produced at Dagdizel are considered among the most advanced in Russia’s arsenal. Since April 2022, Dagdizel has been under US sanctions for its role in supporting Russia’s military aggression against Ukraine.
Earlier, on October 22, long-range drones struck deep inside Russia, targeting the Saransk Mechanical Plant in Mordovia and the DagNefteProdukt oil refinery in Makhachkala, Dagestan. According to ASTRA, both sites are linked to Russia’s defense and energy sectors and are located nearly 1,000 km from the Ukrainian border.
