Bangladesh-China Drone Deal vs India’s Strategic Underground Rail: A New South Asian Security Chessboard

New Delhi: Bangladesh is set to establish a military drone manufacturing facility with China’s assistance, signaling a major shift in South Asia’s defense landscape. In response, India has unveiled plans to construct an underground rail corridor through the strategically sensitive “Chicken’s Neck” region, strengthening a historically vulnerable lifeline.

Bangladesh-China drone factory

Under the recent defense agreement signed on January 27 between the Bangladesh Air Force (BAF) and China Electronics Technology Group Corporation International (CETC), Bangladesh will build a factory for Medium Altitude Long Endurance (MALE) UAVs and VTOL drones near the proposed Bogra airbase. The deal, concluded at the Bangladesh Air Force Headquarters in Dhaka, reflects growing Chinese influence over Bangladesh’s defense capabilities. The drones are expected to serve both military and civilian purposes, including surveillance, reconnaissance, humanitarian aid, and disaster management.

India’s underground rail countermeasure

India’s plan, spearheaded by the North East Frontier Railway’s Katihar Division, involves laying approximately 35.76 kilometers of underground rail connecting Darjeeling (West Bengal) to Kishanganj (Bihar), including the strategically vital 33.40 km section between Dumdangi and Rangpani. This corridor traverses the 22 km narrow Siliguri “Chicken’s Neck” stretch—a region long considered a strategic vulnerability—and will provide secure movement for both civilians and military logistics during emergencies.

Lieutenant Colonel (Retd.) J.S. Sodhi emphasized that the underground rail will not only fortify India’s weak link but also limit the effectiveness of drones monitoring the border. Anti-drone systems, such as the DRDO-developed D4 system (“Detect, Deny, Destroy”), could neutralize enemy UAVs within a 3–4 km radius using radar, radio frequency jammers, or laser-based neutralization.

Strategic stakes and regional security

With a 4,096 km shared land border, any defense development in Bangladesh holds critical significance for India. Analysts note that MALE UAVs operating from Bangladesh could conduct surveillance and electronic intelligence collection close to Indian airspace, potentially feeding data back to Beijing. This has raised concerns about China’s growing influence in South Asia, particularly in the post-2024 geopolitical reconfiguration under Bangladesh’s interim leader Mohammad Yunus.

Observers also see India’s underground rail initiative as a strategic counterbalance to maintain secure supply lines and troop mobility, reinforcing a historically vulnerable corridor and mitigating the potential threat posed by Chinese-supported UAV operations along the Bangladesh border.

As both nations deploy technology and infrastructure for defense and intelligence purposes, the South Asian security environment is entering a complex new phase, where subterranean rail lines meet the skies swarming with drones.
