Sentry Tower — autonomous solar-powered perimeter sensor mast
Solar-powered autonomous sensor mast — radar, EO/IR, acoustic and RF in one tower, runs unattended for years.
The Sentry Tower is Anduril's flagship autonomous perimeter sensor — a 9.7 m solar-powered mast carrying the company's wide-area radar, EO/IR turret, RF detector and on-edge AI classifier. Each tower runs unattended on solar plus battery for the full mission life, mesh-networks to neighbouring Sentries via Lattice OS and reports detections in real time without operator polling. US Customs and Border Protection deployed 300+ Sentry-class towers along the southern border (CBP IFT contract) and Sentry was selected for the US Marine Corps Installation-Counter-small UAS programme (I-CsUAS) in 2024. Configurations exist for fixed installations, rapid-deploy trailers and ship-borne masts.
