Druzhba pipeline
The Druzhba pipeline (Russian: нефтепровод «Дружба», Czech: Ropovod Družba), also called the Friendship Pipeline and the Comecon Pipeline, is one of the world's longest oil pipelines and one of the largest oil pipeline networks in the world. It has been in operation since 1964. It carries oil over 4,000 kilometres (2,500 mi) from the eastern part of European Russia to points in Ukraine, Belarus, Poland, Hungary, Slovakia, the Czech Republic and Germany. The network also branches out into numerous smaller pipelines to deliver oil throughout Eastern Europe and beyond.
The name "Druzhba" means "friendship", alluding to the fact that the pipeline established friendly relations between the Soviet Union and Eastern Europe through reliable supply of oil. Today, it is the largest principal artery for the transportation of Russian and Kazakh oil across Europe.
In August 2025, as part of its war efforts during the Russian invasion of Ukraine, Ukraine's armed forces bombed two pumping stations of the pipeline, causing it to temporarily halt operations.
