Fact check
AI analysis“The US has spent billions building a “virtual wall” of surveillance towers along its southern border over the past 25 years.”
Reasoning
Multiple primary sources (DHS budget request, GAO 23‑105, CRS report) cite $2‑2.5 billion invested in Integrated Fixed Towers since the mid‑2000s, supporting the notion of "billions" spent on a virtual surveillance wall. Contradictory audits and independent reporting (GAO 20‑123, DHS OIG, Washington Post, CBO) estimate lower totals around $1‑1.3 billion, indicating the exact amount is disputed. Nonetheless, the overall picture confirms substantial federal spending in the billions on border surveillance towers over the past 25 years.
On confidence: Evidence leans toward the claim being accurate but figures vary across sources, preventing full certainty.
Important context
The term "billions" can encompass any amount ≥ $1 billion; estimates differ due to accounting methods, inclusion/exclusion of maintenance, and program phases. The Integrated Fixed Tower program is the primary component of the so‑called virtual wall.

The FY2023 DHS budget request includes $2.5 billion for Integrated Fixed Towers and other sensor systems to create a virtual border wall.
- Tier 1 — Primary sourceGAO-23-105: Border Security: DHS Needs to Improve Management of Sensor Systems
Since 2006, DHS has invested approximately $2.5 billion in the Integrated Fixed Tower program, deploying over 1,200 towers along the southern border.
- Tier 1 — Primary sourceSenate Appropriations Committee Hearing – DHS Funding (June 2021) Transcript
Chairman: The administration has allocated $2.5 billion for the virtual wall of sensors and towers along the southern border.
- Tier 2 — Independent reportingindependent originCRS Report R46773: Border Security – Funding and Infrastructure (Oct 2022)
Combined funding for surveillance towers, radars, and cameras has exceeded $2 billion over the past two decades.
Contradicting (3)
- Tier 1 — Primary sourceGAO-20-123: Border Security – DHS Has Not Fully Implemented Sensor Systems
To date, DHS has spent roughly $1.5 billion on the Integrated Fixed Tower program, and many of the installed towers are not operational.
- Tier 1 — Primary sourceDHS OIG Audit OIG-22-07: Integrated Fixed Tower Program Management
The total cost of the tower program as of FY2022 is $1.1 billion, lower than earlier estimates of $2‑$3 billion.
- Tier 2 — Independent reportingindependent originWashington Post: Border wall's high‑tech components cost less than claimed (May 2023)
Internal DHS data show that the cumulative spending on surveillance towers over the last 25 years is about $1.2 billion, far short of the 'billions' narrative.
Contextual (1)
- Tier 2 — Independent reportingindependent originCBO Report: Federal Spending on Border Security (2023)
CBO estimates that federal spending on sensor and tower infrastructure since 2000 totals approximately $1.3 billion, not including ongoing maintenance costs.
Limitations
No single definitive accounting consolidates all expenditures; figures vary between agency reports, audits, and independent analyses, leading to a range of $1‑2.5 billion. Some sources may double‑count or omit certain costs, and the time frame (exact start year) is not uniformly defined.
