In a significant escalation of measures against Pakistan, India has deployed advanced jamming systems along its western border aimed at disrupting the navigation capabilities of Pakistani military aircraft, according to government sources. These jammers are reportedly capable of interfering with all major satellite-based navigation platforms, including the American GPS, Russian GLONASS, and Chinese Beidou systems — all of which are integral to Pakistan’s military aviation.
The deployment coincides with India’s decision to formally close its airspace to all Pakistani-registered, operated, or leased aircraft — both military and civilian — from April 30 to May 23. The closure affects all four major Indian Flight Information Regions: Delhi, Mumbai, Chennai, and Kolkata.
Sources indicate the jammers are intended to compromise Pakistan’s situational awareness and targeting precision, particularly in the event of military conflict. By degrading the effectiveness of precision-guided munitions and disrupting satellite-based navigation, the move is seen as a strategic deterrent.
The airspace ban follows the deadly April 22 terror attack in Pahalgam, which claimed 26 lives and escalated tensions between the two nuclear-armed neighbors. In response, India has taken a series of retaliatory steps, including suspending the Indus Waters Treaty and revoking visas for Pakistani nationals.
With Indian airspace now off-limits, Pakistani airlines — including the national carrier, Pakistan International Airlines (PIA) — are being forced to reroute via Chinese or Sri Lankan airspace to reach Southeast Asian destinations such as Kuala Lumpur. These longer routes are expected to increase operational costs significantly due to higher fuel consumption, longer flight times, and logistical complications.
While Pakistani carriers face operational strain, Indian airlines like IndiGo and Air India — with their substantially larger fleets — remain unaffected, further tipping the regional aviation balance in India’s favor.
India’s latest measures underscore the deepening strain in bilateral relations and signal a more aggressive posture in dealing with cross-border security threats.
