California Chemical Tank Emergency At F-35 Supplier Comes Amid Far-Left Campaign Against Defense Firms

By the end of last week, dozens of lawsuits had been filed against GKN Aerospace after a tank explosion risk at its Garden Grove, California, facility forced 40,000 residents to evacuate the area over Memorial Day weekend.

An apparent malfunctioning storage tank containing methyl methacrylate, a volatile, flammable chemical, sparked fears of an explosion across Garden Grove, Anaheim, Stanton, Buena Park, Cypress, and Westminster.

Local authorities lifted the final evacuation orders last Tuesday after pressure inside the tank stabilized and officials ruled out the worst-case explosion scenario.

While much of this has already been reported, what has not been widely discussed is that GKN Aerospace's Garden Grove facility is part of the critical supply chain that manufactures components for the F-35 stealth fighter jet. This comes as far-left Marxist groups, under the guise of 'Palestine,' have targeted critical nodes of the F-35 supply chain across the West.

GKN's own website states that its Garden Grove production line manufactures the "world-leading F-35 canopy," as well as other advanced military and commercial aircraft transparency systems. This makes the facility deeply embedded in the F-35 supply chain.

This all matters because the chemical emergency at the Garden Grove facility was not just an industrial incident. It may have a profound impact on canopy production for the world's most advanced stealth fighter jet program, while orders for the jet ramp up among U.S. allies.

In recent weeks, Canary Mission claimed on X that Palestine Action and its U.S.-based network, Unity of Fields, had circulated a target map containing personal information and civilian addresses allegedly tied to Israel's defense-industrial base in the US.

InfluenceWatch describes Unity of Fields as the former Palestine Action U.S. and says its US branch is focused on "their goal is to dismantle the ability for the Israeli state to carry out its foreign policy objectives by obstructing the facilities that produce arms for Israel."

InfluenceWatch has also reported that Marxist James "Fergie" Chambers, an heir to the Cox Enterprises family fortune, has provided financial support for Palestine Action members.

InfluenceWatch noted, "Palestine Action was created in July 2020. Its opening act was to vandalize the U.K. headquarters of defense contractor Elbit Systems, which conducts business with the State of Israel."

The Garden Grove tank failure has reportedly been blamed on a faulty valve in the cooling system. While that suggests an industrial malfunction, the timing cannot be ignored. Radical left networks have increasingly targeted the F-35 supply chain and defense contractors, placing facilities like GKN's Garden Grove site in the crosshairs of left-wing pro-terror groups.

While no direct link has been established - the incident is likely to be a wake-up call for US defense firms.
