Tel Aviv: Should European NATO members be concerned about the possible use of the “Kill Switch” by the US in case of a crisis related to NATO’s future gets more serious?
The issue is also being discussed in Israel. “If tomorrow the administration in Washington wants to change its attitude, is this option a real threat?,” one Israeli source asked.
European countries operating advanced US-made weapon systems like the F-35 Lightning II, Patriot missile defences, HIMARS, and Link 16 networks have expressed significant concerns about potential US control mechanisms, often called a “Kill Switch” or “Off Switch,” amid tensions under President Trump’s administration.
All the sources pointed out that there is no confirmed evidence that such a “Kill Switch” exists. But instead, the US can instantly disable systems mid-operation, such as shutting down F-35s in flight. The US leverage stems from Software dependencies: F-35 requires frequent updates via ALIS/ODIN systems managed by Lockheed Martin; withholding them degrades mission data files (MDF) and combat effectiveness rapidly.
While there is no public proof of a secret, remote “Kill Switch” in US supplied main systems, the US retains significant levers of control through logistics and software upgrades.
Experts suggest the US does not need a “Kill Switch” to disable weapons. Instead, it can block access to critical maintenance, logistics, and supply chains like spare parts for F-35 engines or airframes. According to the experts, the US can also restrict access to US-controlled networks like Link 16, essential for modern network-centric warfare.
