Written and published by Etienne Matuszewski Imagine a missile streaking across the sky at speeds exceeding Mach 5—faster than sound, nearly impossible to intercept. In a split second, it’s neutralized. That’s exactly what Lockheed Martin achieved during Flight Test Other 40 (FTX-40), codenamed Stellar Banshee. On March 25, 2025, off the coast of Kauai, Hawaii, the USS Pinckney (DDG 91) detected, tracked, and engaged a live hypersonic Medium-Range Ballistic Missile (MRBM) using a simulated SM-6 Block IAU interceptor. This test marks a significant leap forward in the race to counter hypersonic threats. A Breakthrough in Missile Defense Lockheed Martin, in collaboration with the Missile Defense Agency (MDA), the U.S. Navy, and industry partners, designed a test scenario to push the Aegis Combat System to its limits in a simulated hypersonic attack environment. Stellar Banshee validated the system’s ability to adapt to emerging threats using a cutting-edge virtualized software archi...
