In the early hours of June 14, a massive sabotage operation took place deep inside Russian territory. Ukrainian military intelligence, known as HUR, carried out a bold and secret mission in the Russian city of Kaliningrad.
Fire and Damage in Kaliningrad
Their target was an important electrical substation. The operation caused extensive destruction—resulting in an estimated $5 million in damage. The fire not only wrecked the substation but also cut off power to a nearby Russian military production site, disrupting critical infrastructure linked to the war effort.
The plan was carefully designed. Ukrainian agents removed the coolant from the substation’s power transformer. This transformer is a big machine that helps control and move electricity. Without coolant, the transformer overheats very quickly. Once it was hot enough, the agents set it on fire. This caused a large explosion and a fire that damaged the whole substation.
The damage was not small. Experts say the destruction could cost Russia around $5 million. But the money wasn’t the only problem for Russia. The power outage also hit a military production site in the area. This site likely supports the Russian war effort in Ukraine. So, losing power affected more than just lights and machines—it may have disrupted military work as well.
The Ukrainian military intelligence source said that Russia no longer has a “safe zone.” In simple words, they meant that wherever Russia stores military tools or supports the war, it is not safe anymore, no matter how far it is from Ukraine.
Attacks Far Beyond the Frontline
This sabotage in Kaliningrad is just one example of many similar operations Ukraine has been carrying out. These are not battles with tanks and soldiers in the open. Instead, they are silent and hidden missions deep inside enemy areas. The targets are usually military sites, like airports, oil depots, railway stations, and factories.
These secret missions are carried out not only by HUR but also by the Security Service of Ukraine (SBU) and various partisan groups. Partisan groups are people who live in or near these areas and secretly work against Russia.
One of the boldest operations happened on May 30, near Desantnaya Bay in Russia’s far eastern city of Vladivostok. If reports are true, this attack took place about 6,800 kilometers away from Ukraine’s border. That is a very long distance—almost as far as traveling across an entire continent. Explosions there reportedly damaged Russian military equipment and personnel. This would be the farthest Ukrainian sabotage mission inside Russia so far.
These operations show that Ukraine is using intelligence, planning, and technology to strike deep inside areas once thought safe by Russian forces. The damage caused in these areas may not always be visible to the public, but the impact on Russian military activities could be serious.
Operation Spiderweb and Other Drone Strikes
On June 1, Ukraine launched another large-scale attack with the help of drones. This was called Operation Spiderweb. Drones are small flying machines that can be controlled from far away. They are often used to take pictures or deliver packages. But in war, drones are used to gather information or to carry bombs and destroy targets.
In this operation, drones attacked four major Russian military airfields. These airfields are where military planes take off and land. The drone strikes caused major damage. Reports say 41 planes were hit. These included large bombers and A-50 spy planes. A-50 planes are special planes that help track enemy movements from the sky. They are rare and very important for planning military attacks.
Damaging so many planes in one mission is a big loss for Russia. It shows how effective Ukraine’s secret drone missions have become. These operations take careful planning, knowledge of enemy locations, and high-level coordination.
Ukraine has also carried out drone attacks on other important places inside Russia. Oil refineries, fuel storage tanks, and railway hubs have all been hit. These attacks weaken the supply lines and reduce the enemy’s ability to continue military operations.
Every time Ukraine targets such places, it reminds Russia that even areas far from the battlefield are not out of reach.
Ukraine’s strategy now includes using secret missions and drone warfare in addition to regular ground fighting. These methods allow Ukraine to hit important military and infrastructure targets without needing a full-scale army on the ground. The Kaliningrad sabotage and Operation Spiderweb are just two examples of this growing strategy.
Each successful attack brings damage not only to Russian military systems but also sends a strong message: even the most protected or distant places may no longer be safe from Ukrainian strikes.
