Smiths Detection to Provide LCD 4 for the Japan Ground Self-Defense Forces
Smiths Detection, a global leader in threat detection and security screening technology, has officially announced that it will supply its LCD 4 personal chemical detector to the Ministry of Defense for deployment in the Japan Ground Self-Defense Forces. This contract marks a significant milestone in the ongoing efforts of Japan’s defense sector to enhance its chemical threat detection capabilities.
The selection of the LCD 4 highlights the Ministry of Defense’s commitment to equipping personnel with state-of-the-art safety and detection tools. The LCD 4 is a compact, lightweight, and wearable device designed for real-time monitoring of hazardous chemical threats. With its advanced warning capabilities, it ensures the safety of military personnel by detecting and identifying toxic gases and vapors before they reach levels that are Immediately Dangerous to Life and Health (IDLH). The device utilizes the latest Ion Mobility Spectrometry (IMS) technology to provide accurate identification of the agent, including its type, class, concentration, and dose of exposure.

Extensive Evaluation Process Leads to Selection of LCD 3.3 and LCD 4
After a thorough and rigorous evaluation process, the Ministry of Defense selected the LCD 3.3 and LCD 4 chemical detectors based on their superior performance, reliability, and flexibility. One of the key factors influencing the decision was the ease of integration of these devices into existing Ministry of Defense systems, ensuring seamless operational deployment.
Sarah Robinson, CBRNE Portfolio Director at Smiths Detection, emphasized the significance of this selection:
“The Ministry of Defense’s decision to invest in this technology further underlines the reputation of LCD as the most widely deployed personal chemical detection device within defense organizations around the world. We will customize this newly deployed model to meet the Ministry of Defense’s specific detection requirements, which of course includes a Japanese language option.”
This level of customization ensures that personnel can operate the device with maximum efficiency and ease, further enhancing safety measures for Japan’s defense forces.
Advanced Features and Future Expansion Capabilities
The LCD 4 personal chemical detector is designed to provide comprehensive protection for military personnel in high-risk environments. Its real-time monitoring system allows for the rapid detection of chemical threats, enabling users to take swift protective measures. The device’s ability to detect toxic gases and vapors at trace levels before they become a severe health hazard makes it an essential tool for modern defense strategies.
Furthermore, Smiths Detection has built the LCD 4 with future expansion capabilities in mind. The device can be upgraded with simple XID add-ons, which will extend its detection capabilities beyond gases and vapors. This future enhancement will allow the LCD 4 to detect and analyze solid and liquid samples, as well as identify low-volatility chemicals such as narcotics, explosives, and Novichok – a highly potent chemical weapon. These additional capabilities make the LCD 4 a versatile tool for both military and homeland security applications.
Delivery and Deployment Timeline
Smiths Detection’s distribution partner in Japan, ST Japan, will handle the local delivery of the LCD 4 units. The contract includes a total of 462 units, which will be delivered in stages. The first batch is scheduled for distribution between January and March 2025, with the final phase set for January 2026. This phased delivery approach ensures a smooth and structured integration into the Ministry of Defense’s operational framework.
