## Key points

- Japan has deployed its first operational indigenous stand-off missile systems for enhanced long-range strikes.
- The upgraded surface-to-ship missile, based on the Type 12, now reaches up to 1,000 kilometers.
- Japan's new missile systems can engage both hostile ships and land-based targets like missile launch sites.
- Modern guidance and network-based targeting technologies improve accuracy and operational flexibility of the systems.

Enhanced range and strike capability The deployment represents Japan’s first operational use of indigenous stand-off missile systems—capabilities designed to strike targets from long distances while minimizing exposure to enemy defenses. One of the key components of this modernization effort is the upgraded surface-to-ship missile, derived from the earlier Type 12 system. While the original version had a relatively limited range, the improved variant can reach targets up to approximately 620 miles (1,000 kilometers) away. This extended reach significantly expands Japan’s defensive envelope, enabling it to engage not only hostile naval vessels but also land-based targets such as missile launch sites. The system incorporates modern guidance technologies and network-based targeting, improving accuracy and operational flexibility. Introduction of hypersonic weaponry
