# Anduril Sentry Tower [[Anduril]]'s autonomous surveillance tower system — the "virtual wall" on the US-Mexico border that has become the company's most controversial product. As of January 2026, **585 surveillance towers** have been mapped across the border region by the EFF, and new legislation has effectively granted Anduril a monopoly on future installations. A July 2026 GAO report puts the current CBP tower fleet at ~830 and documents a plan to expand it to **2,300 by 2034** — see [[CBP Integrated Surveillance Tower Expansion]]. ## What It Does Sentry towers are AI-powered autonomous surveillance systems that detect, track, and classify objects without requiring a human operator for initial detection. The AI handles autonomous detection; human agents are alerted for classification and response decisions. Key specifications: **Standard Sentry Tower:** - Autonomous detection range: up to 7.5 miles - Agent-assisted classification range: 3 miles - AI-powered by [[Anduril Lattice]] - No human operator required for detection cycle **Extended Range Sentry Tower (XRST)** (deployed 2024): - Autonomous identification and tracking: up to 5 miles - Human-assisted detection: up to 7.5 miles - Deployed to US-Mexico border, operational in Texas The towers feed into CBP's broader sensor network, creating persistent surveillance coverage across the border region. ## Who Uses It ### U.S. Customs and Border Protection (CBP) Primary customer. CBP is installing 200+ Autonomous Surveillance Towers (ASTs) across the southern border. As of January 2026, the EFF has mapped 585 total surveillance towers. The Sentry Tower was one of Anduril's first products — the company won its initial CBP contract shortly after founding in 2017, which established its credibility as a defense contractor. ### UK Ministry of Defence £17M force protection technology contract. The same towers designed for border surveillance are being deployed for military base protection — a textbook case of [[Dual-Use AI]]. ### International Marketing Being marketed to other countries for border and perimeter surveillance. ## Contract Value The exact cumulative value of all Sentry Tower contracts is difficult to pin down because they span multiple procurement vehicles. Key data points: - Hundreds of millions in cumulative CBP contracts since 2017 - [[Anduril CBP 363M Sentry Tower Contract]] (June 2026) — $363M for 200+ Extended Range Sentry Towers - Part of the $6B+ in border security technology funding in the "One Big Beautiful Bill Act" (signed July 4, 2025) - **GAO-26-108118 (July 2026):** DHS plans to nearly triple the border tower fleet from ~830 to **2,300 by 2034**, spending ~**$1B** from the Big Beautiful Bill — new long-range autonomous towers plus autonomy retrofits of existing towers. Given the certified-autonomous monopoly (below), this is in practice a multi-year Anduril order pipeline.

Legislative Capture / Monopoly The "One Big Beautiful Bill Act" (signed July 4, 2025) includes provisions that effectively grant Anduril a monopoly on new CBP surveillance towers. The law requires all new surveillance towers to be "certified autonomous" by CBP — and only Anduril's towers currently hold this certification. This means the legislation was written in a way that locks out competitors and guarantees Anduril the contract. [[Palmer Luckey]] is a prominent Trump supporter whose company directly benefits from Trump-era border enforcement policies. Critics call this legislative capture by a politically connected defense contractor. ### 2. Privacy Violations The Government Accountability Office (GAO) reported in 2024 that CBP's surveillance tower program failed to address all six of the main privacy protections that were supposed to be in place, including the rule that DHS should collect only personally identifiable information (PII) that is directly relevant and necessary to the specified purpose. In other words, the surveillance is collecting more data about more people than the rules allow — and the safeguards aren't working. ### 3. "Virtual Wall" Critique Civil liberties organizations — including the EFF, ACLU, Privacy International, and the Migrants' Rights Network UK — argue that: - The towers are a "virtual wall" that doesn't stop migration but pushes people into more dangerous crossing routes, increasing deaths - The surveillance infrastructure can be repurposed for tracking citizens, protesters, and communities near the border - The AI detection systems have not been independently audited for accuracy, false positive rates, or bias - The scale (585+ towers) represents a mass surveillance infrastructure unprecedented in U.S. border history ### 4. Dual-Use Creep The same technology sold to CBP for immigration enforcement is now being marketed for military base protection (UK MoD), domestic law enforcement, and international border control. The pathway from "border security" to general surveillance mirrors the trajectory of [[Palantir Gotham]] from counterterrorism to predictive policing. ### 5. Palmer Luckey's Political Alignment Luckey's personal political history — the Nimble America funding, the connection to Trump-aligned politics, the $100M Facebook buyout that funded Anduril — means the company's border surveillance contracts carry an additional layer of political controversy. Critics see a direct pipeline from Trump's border policies to Luckey's bank account. ## Historical Context The U.S. government's border surveillance tower programs have a long history of failure. The EFF has documented that previous iterations — including Boeing's SBInet program, which was cancelled in 2011 after wasting $1B — consistently overpromised and underdelivered. Anduril's Sentry Tower is the latest attempt, and while it has performed better than predecessors, the fundamental critique remains: surveillance towers don't reduce unauthorized migration, they just make it more dangerous and more surveilled. ## See Also - [[CBP Integrated Surveillance Tower Expansion]] — GAO-documented plan to triple the tower fleet by 2034 - [[Anduril CBP 363M Sentry Tower Contract]] — June 2026 XRST award - [[Anduril Product Ecosystem]] — Master reference - [[Anduril]] — Company record - [[Palmer Luckey]] — CEO and Trump supporter - [[Anduril Lattice]] — AI platform - [[Dual-Use AI]] - [[Palantir ICE Systems]] — Comparable immigration tech controversy - [[Stephen Miller]] — Immigration enforcement architect - [[Tanton Network]] — Anti-immigration infrastructure - [[Military-Industrial Complex 2.0]]
