Catch up to the first two weeks of the Integrated Field Exercise 2026: from the launch phase week in Vienna, to the field operations week in Swakopmund and the Erongo Region, in Namibia. The participants have entered a routine after a busy week of activities, and now they regularly coordinate the field-gathering missions, collect data, and use search logic to further advance their work and narrow down the exercise inspection area. The IFE26 aims to validate and refine on-site inspection capabilities in preparation for the #CTBT’s entry into force. ctbto.info/m/IFE26

A year ago, the world lost Jane Goodall. In The Road to Zero, she speaks about the CTBT as plainly as she spoke about everything that mattered to her: proud of how far it has come, unflinching about what’s left, countries still to sign and ratify. Her words are part of our short film. 🎥 Watch the full film: ctbto.info/R20ShortFilm

The 70th session of #CTBTO’s Working Group A opened in Vienna, with Executive Secretary @DrRobFloyd highlighting key achievements: a growing Treaty family, a near-complete global monitoring system and the ongoing #IFE26 in Namibia. “We’ve invested so much to achieve all of this. We now need to focus on protecting that investment in the years ahead.” He stressed the importance of sustainment, modernisation and long-term readiness, and thanked 🇵🇭 Amb. Evangelina Lourdes Bernas for her leadership as WGA Chair.

Under #NDCs4All, a new Capacity Building System (CBS) has been installed in Benin, providing access to International Monitoring System (IMS) data and International Data Centre (IDC) products. The mission also strengthened regional cooperation through exchanges of knowledge and experience between the National Data Centres of Benin and Togo, supporting scientific applications and enhancing global #CTBT verification capabilities.

The CTBTO’s Integrated Field Exercise (#IFE26) has moved into the field operations in Namibia. Within the fictional scenario, teams are laying the groundwork for the start of the exercise inspection activities in the field: from the arrival at the Point of Entry procedures to negotiations, equipment check and transport, and establishing the Base of Operations. Our thanks to Namibia for hosting, actively participating and helping make this international exercise possible.

On the Intl. Day for Disaster Risk Reduction, a word about what our network does beyond its core purpose. The Intl. Monitoring System exists to detect nuclear test explosions. The data it collects also helps identify earthquakes and other events that can generate tsunamis, reaching tsunami warning centres in near real-time under agreements with the States Signatories that operate them. #DRRDay More: ctbto.info/DataUses

The first CTBTO Integrated Field Exercise (IFE26) in Africa, hosted by Namibia, will bring together more than 250 experts to evaluate on-site inspection capabilities, share expertise and strengthen cooperation. Hear from those helping make IFE26 possible. ctbto.info/m/IFE26

#OTD in 1963, the Partial Test Ban Treaty entered into force, prohibiting nuclear test explosions in the atmosphere, outer space and under water. It marked the first international limits on testing and laid the groundwork for the comprehensive ban set out in the #CTBT.

At the Africa Group Plenary in Vienna, @DrRobFloyd thanked Ghana for chairing the group and for a milestone in March: the first regional commemoration of the Treaty’s 30th anniversary. The Executive Secretary pointed to a continent that today hosts 38 monitoring stations and 42 National Data Centres, and looked ahead to #IFE26, starting in October in Namibia, the most ambitious Integrated Field Exercise the Organization has ever run.

The #CTBTO Integrated Field Exercise (IFE26) launch phase is underway. #IFE26 continues this week with in-house preparations and consultations with the exercise’s Requested State Parties (RSP), Nirland and Logor, and the Inspected State Party (ISP) of Lumaria. These Treaty-based procedures and steps are an essential part of setting up the framework for exercise activities in the field in Namibia. ctbto.info/m/IFE26

More than 2,000 nuclear test explosions before 1996. Fewer than a dozen since. “The tap is almost turned off,” says CTBTO Executive Secretary @DrRobFloyd. 30 years of the Treaty, in a two-minute 🎥 explainer from the @UN. ctbto.info/UNExplainer

From Vienna to New York, the 30th anniversary of the #CTBT brought together leaders, diplomats, and partners to reflect on three decades of progress and reaffirm the work that lies ahead to achieve a world free of nuclear test explosions. The commemorations underscored a shared message: the Treaty remains essential to advancing global peace and security. 🔗 Read the full story: ctbto.info/30-years-ctbt-ann…

30 years ago, the world was still testing nuclear weapons: more than 2,000 of them since 1945, underground, beneath the ocean and high in the sky. Then the international community set out to end it: a Treaty, and a system to prove it was being kept. It’s worked: fewer than a dozen declared tests since. The Road to Zero tells that story. 🎥 Watch the full film: ctbto.info/R20ShortFilm

The #CTBTO Integrated Field Exercise (IFE26) is officially underway! The realistic scenario started the clock with the request for an on-site inspection (OSI) being received, triggering the activation of the Operations Support Centre (OSC) and internal preparations. 
IFE26 will go through the procedures and steps of an OSI prescribed by the Treaty, which can be requested by States Signatories once the #CTBT enters into force. It will be one of the most comprehensive multinational exercises in nuclear non-proliferation and disarmament. Stay tuned for more updates from #IFE26! ctbto.info/m/IFE26
