Tungsten Frenzy: Geopolitics Sends ‘War Metal’ Prices and A‑Share Valuations Skyward
Tungsten prices in China have surged more than 70–80% year‑to‑date after recent geopolitical shocks and persistent supply constraints, lifting A‑share tungsten producers to extreme valuations. The spike reflects the metal’s military applications and concentrated Chinese supply, but raises questions about the sustainability of profits and the risk of a market correction.
New F-35 Deliveries Arrive Without Radar, Exposing Production and Readiness Fault Lines
A report says Lockheed Martin delivered recent F-35s without AN/APG-85 radars, and the mounting differences prevent fitting the earlier AN/APG-81 as a substitute. The deliveries could constrain the jets' combat roles, strain depots and suppliers, and prompt political and allied scrutiny of the F-35 programme.
Newest F-35s Reportedly Delivered Without Functional Radar, Raising Readiness and Industrial Concerns
A report says Lockheed Martin delivered a batch of F-35s since June 2025 without the AN/APG-85 radar installed, leaving only the radar pedestal and preventing simple retrofit with the older AN/APG-81. The gap could degrade readiness, increase retrofit costs and spotlight supply-chain and integration strains within the U.S. defense-industrial base.
