Readiness isn't built overnight. It is refined and demonstrated over time. ▶️Hear from #CTBTO On-Site Inspection Director Oleg Rozhkov on how the Integrated Field Exercise 2026 (#IFE26) will help validate capabilities, strengthen international cooperation, and advance operational readiness of the Treaty's on-site inspection component.

On this day in 1945, the world witnessed its first nuclear explosion with the Trinity Test. In the following decades, more than 2,000 such tests followed – until the #CTBT opened for signature in 1996. Since then, fewer than a dozen tests have taken place worldwide.

On this day we mark the anniversary of the entry into force of the Treaty of Pelindaba, a landmark agreement making Africa a nuclear-weapon-free zone. The Treaty demonstrates the region's dedication to a nuclear-weapon free future and its strong stand against nuclear tests. See how CTBTO works with Africa: ctbto.info/AfricaBrochure

In 2014, a cable snapped 189 km off Diego Garcia 🗺️, and one of the world's most remote listening posts, part of the International Monitoring System (IMS) hydroacoustic network, went dark. 12 years on, a team of @CTBTO engineers, station operators and contractors found it, tested it, and brought it back to life. Thanks to the US and the UK, with additional support from Denmark, Finland, Israel and Slovakia. 📷 Here's how HA08 North came back online, and what this means for global nuclear test explosion monitoring: ctbto.info/HA08WebStory

Pleased to welcome Tonga to the family of #CTBT ratifiers, all the more meaningful in the Treaty's 30th anniversary year. The Pacific has felt the devastating impact of explosive nuclear testing, and has long been at the forefront of the fight to end it. Universalisation is not just a symbol of unity: it is a clear and collective stand for a better future for all. Grateful to all the Tongan officials and regional partners who helped make this happen.

A first for the International Monitoring System (IMS): all 11 stations in the hydroacoustic network are now mission capable, every light green. With the successful repair of HA08 North, hydroacoustic becomes the first IMS technology to reach this milestone.
