Yoshihiro Inaba discusses the Japan’s future AEGIS System Equipped Vessel (ASEV) — an advanced, large, stealth guided-missile destroyer — and the SPY-7 radar system with Lockheed Martin's Paul Lemmo during DSEI Japan 2025.
=====================
At the DSEI Japan 2025 in Tokyo, Lockheed Martin was showcasing a mock-up of Japan’s under-development ASEV. The stealth guided-missile destroyer will specialize in ballistic missile defense (BMD) — larger than any other destroyer in the world, excluding the unique Zumwalt-class of US Navy.
According to the Japanese Ministry of Defense (MoD), the ASEV measures 190 meters in length, 25 meters in width, and has a standard displacement of 12,000 tons (the full load displacement could exceed the 14,000 tons). By comparison, the JMSDF’s latest Maya-class destroyer is 170 meters long, 21 meters wide, with a standard displacement of 8,200 tons. The ASEV is also 1.7 times heavier than the US Navy’s newest Arleigh Burke-class Flight III destroyer in terms of displacement.
Unlike the AN/SPY-1 radar system installed on Japan’s eight existing AEGIS destroyers (Kongō, Atago, and Maya classes), this vessel will be equipped with the more advanced AN/SPY-7 AESA multi-function radar, which is also set to equip the Canadian River-class destroyers and the Spanish F-110 frigates.
