EXCLUSIVE: Documents Reveal US Contractor’s Modifications of Spy Plane Just Before Flights Over Gaza

Key Takeaways

• UK RAF used US‑modified King Air 350ER for Gaza surveillance
• Sierra Nevada Corp’s aircraft broadcast live flight data by mistake
• Flights coincided with Israeli strikes killing dozens of civilians
• Legal experts say intelligence may aid war‑crime allegations
• Contractor’s defense contracts total tens of billions of dollars

Pulse Analysis

The disclosed FAA records illuminate a little‑known partnership between the British Royal Air Force and American defense contractor Sierra Nevada Corporation. While the UK framed the surveillance missions as essential for locating hostages taken during the Oct. 7 Hamas attack, the aircraft involved were U.S.‑built King Air 350ER platforms that had been extensively altered for high‑altitude intelligence gathering. The partnership, spanning nearly two years, underscores how Western allies increasingly outsource critical ISR (intelligence, surveillance, reconnaissance) capabilities to private firms, blurring the line between state and corporate responsibility in conflict zones.

A striking incident on July 28, 2025 highlighted operational vulnerabilities. A Sierra Nevada pilot failed to deactivate a live‑broadcast transponder, allowing anyone with the right software to track the plane’s exact route over central Gaza. The aircraft lingered as Israeli strikes killed at least 23 Palestinians, including women and children, prompting human‑rights advocates to argue that the data streamed from the flight could have been used to refine targeting. Legal scholars warn that providing such intelligence may constitute aiding and abetting war crimes, exposing both the UK and the United States to potential prosecution under international law.

The episode raises broader questions about the governance of defense contracting and the oversight of overseas surveillance. Sierra Nevada Corporation, a Nevada‑based firm with defense contracts worth tens of billions of dollars, rarely appears in headlines, yet its role here illustrates how private contractors can become pivotal nodes in geopolitical conflicts. Policymakers are now pressured to tighten reporting requirements, enforce stricter export‑control regimes, and ensure that intelligence gathered abroad complies with humanitarian law. As the debate intensifies, the incident may catalyze reforms that balance operational effectiveness with accountability, reshaping how allied nations employ commercial ISR assets in future conflicts.
