IRGC's Ali Taher ridge tunnels in Lebanon tallied at tens of billions over two decades
The Islamic Revolutionary Guard Corps constructed the tunnel network beneath Lebanon's Ali Taher ridge over roughly two decades, at a cost placed in the tens of billions of dollars. That figure, tied to a single underground infrastructure program, puts the IRGC's long-cycle capital deployment in Lebanese territory in focus.
Key takeaways
- The IRGC built a tunnel network beneath Lebanon's Ali Taher ridge over roughly two decades of continuous construction.
- The reported cost of the tunnel program is placed in the tens of billions of dollars, according to sourced reporting.
- The build required sustained operational capacity, including consistent material flows and engineering throughput maintained across about 20 years.
- The IRGC ran the program to completion, producing underground infrastructure that is not easily dismantled once complete.
- The tens-of-billions cost figure has not yet been independently verified.
The Islamic Revolutionary Guard Corps constructed the tunnel network beneath Lebanon's Ali Taher ridge over roughly two decades, at a cost placed in the tens of billions of dollars. That figure, tied to a single underground infrastructure program, puts the IRGC's long-cycle capital deployment in Lebanese territory in focus.
Twenty years of continuous construction demands sustained operational capacity: consistent material flows and engineering throughput maintained across an extended period. The IRGC kept that program running to completion. The total bill, by the sourced figure, reached the tens of billions. A build of that duration and cost represents a significant commitment of resources to infrastructure that is underground and, once complete, not easily dismantled.
What to watch is independent verification of the reported cost estimate and a clearer accounting of the tunnel network's current condition. The tens-of-billions figure rests on sourced reporting; corroboration would sharpen both the scale of the build and what it represents as a resource-allocation question for the IRGC's operations abroad.
