Why Did Lockheed Martin Stock Drop Today?

Lockheed Martin shares fell 2.7% by about 1:50 p.m. ET Thursday, despite the article’s focus on a “positive” catalyst. It points to Lockheed’s participation in RIMPAC (Exercise Rim of the Pacific) 2026, where it reportedly demonstrated a partnership with Saildrone. A Saildrone Surveyor unmanned craft was used to remotely fire Lockheed-built Joint-Air-to-Ground Missiles (JAGMs) at a mock high-speed motorboat target. The demonstration also highlighted threat-identification radar and electronic warfare systems aimed at countering hostile drones. The companies plan to expand cooperation using larger Spectre-class vessels for containerized weapon systems, including Mk 70 vertical launchers and SURTASS towed-array sonar. The article questions why the stock dropped.
