These technologies have become essential as Hamas’s underground network, sometimes called the “Gaza Metro,” is believed to stretch for hundreds of kilometers
The IDF has invested heavily in underground‑detection technology in Gaza, relying on a combination of seismic sensors, ground penetrating radar, and electromagnetic mapping to locate Hamas tunnels beneath dense urban terrain.
Israel began developing these systems after the 2014 Gaza war, when Hamas’s expanding tunnel network became one of the most significant threats to Israeli troops and civilians.
By 2021, Israel completed a multilayered underground barrier along the Gaza border, integrating radar arrays, vibration sensors, and artificial‑intelligence analysis tools developed by Elbit Systems, Israel Aerospace Industries, and the Defense Ministry’s research directorate, MAFAT.
