GPS Jamming and Spoofing Now Disrupts Thousands of Flights Monthly

Over the past three years, more than 580,000 instances of GPS signal loss have been recorded across global aviation, and GPS spoofing attacks now disrupt thousands of flights every month. Cheap jamming devices costing under $50 can deny GPS service across a wide area, while spoofing equipment can feed false position data to military and civilian receivers simultaneously. In June 2025, electronic interference with navigation systems was suspected as a contributing factor in the collision between two oil tankers off the coast of the UAE. This matters because modern militaries depend on GPS for everything from precision-guided munitions to troop movement coordination and logistics. When GPS is degraded, smart weapons become dumb, drone operations halt, and coordinated maneuvers collapse. The U.S. military's 2025 budget requested $1.5 billion for more resilient positioning, navigation, and timing (PNT) programs, which itself signals the severity of the gap. The downstream effect is that the entire kill chain — from sensor to shooter — slows or breaks when GPS is denied. The problem persists structurally because GPS was designed in the 1970s as a one-way broadcast system with no authentication or encryption on the civilian signal. The military's encrypted M-code signal exists but has been painfully slow to deploy across fielded equipment. Most military platforms still rely on legacy GPS receivers that accept any signal on the right frequency without verifying its authenticity. Upgrading millions of receivers across every branch, ally, and platform is a decade-long logistics problem that no single budget cycle can solve. Meanwhile, adversaries only need a $50 jammer to exploit the gap.
