Lockheed Martin Delivers Second Shipment of ASEV Shipsets and AN/SPY-7(V)1 Equipment to Japan

Why It Matters

The delivery bolsters Japan’s maritime defense capabilities and deepens U.S.–Japan security cooperation, reinforcing deterrence across the Indo‑Pacific region.

Key Takeaways

• Second AN/SPY-7(V)1 shipset delivered on schedule.
• Two ASEVs slated for 2027‑2028 commissioning.
• Radar offers solid‑state, multi‑target tracking capability.
• Direct Commercial Sale via Mitsubishi streamlines procurement.
• Enhances Japan’s Indo‑Pacific maritime defense posture.

Pulse Analysis

The ASEV program represents a cornerstone of the U.S. and Japanese partnership to modernize naval forces in a contested Indo‑Pacific. By integrating Lockheed Martin’s AN/SPY-7(V)1 radar, the vessels gain a high‑resolution, solid‑state sensor suite capable of detecting low‑observable threats at extended ranges. This delivery, the second of its kind, underscores the effectiveness of the Direct Commercial Sale model, which leverages Mitsubishi’s local presence to accelerate logistics and reduce bureaucratic friction.

Technically, the SPY‑7(V)1 radar distinguishes itself with modular, gallium‑nitride (GaN) transmit/receive modules that deliver superior power efficiency and rapid beam steering. Its multi‑function capability supports simultaneous air, surface, and ballistic‑missile tracking, enabling a single sensor to replace legacy radar arrays. The pre‑integration testing conducted by Lockheed Martin before shipment mitigates on‑site integration risk, shortening the path to operational readiness for the Japanese fleet.

Strategically, the two ASEVs slated for commissioning in FY2027 and FY2028 will expand Japan’s layered defense architecture, providing early warning and fire‑control data to both national and allied platforms. The successful, on‑time deliveries reinforce confidence in Lockheed Martin’s supply chain and may catalyze further sales of SPY‑7 technology to other allies seeking advanced, scalable radar solutions. As regional tensions rise, the enhanced situational awareness afforded by these vessels will be a decisive factor in maintaining maritime stability.
