Namibia has made history by hosting Africa’s first major international exercise designed to strengthen the global system for detecting and investigating suspected nuclear test explosions.
The Integrated Field Exercise 2026 (IFE26), organised by the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), is taking place from October 10 to November 20 in Swakopmund and surrounding areas of the Erongo Region. The exercise brings together approximately 250 international participants to test the procedures, equipment and expertise needed to investigate a suspected nuclear test.
According to the CTBTO, approximately 150 tonnes of specialised equipment are being transported to Namibia by air and sea to support the six-week operation.
Testing Global Nuclear Verification Capabilities
The exercise simulates a fictional nuclear explosion, allowing international inspectors and technical experts to practise collecting and analysing evidence in a realistic field environment.
Activities include deploying scientific equipment, managing inspection operations and evaluating evidence to determine whether a nuclear test may have occurred. The scenario is a training exercise and does not involve actual nuclear explosions or nuclear materials.
The exercise is part of preparations for implementing the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which prohibits nuclear explosions worldwide. On-site inspections are intended to provide a final verification measure when other monitoring systems cannot conclusively resolve concerns about a possible nuclear test.
Namibia’s Role in Nuclear Disarmament
Namibia’s hosting of the exercise highlights its contribution to international peace, security and nuclear non-proliferation efforts. The country also hosts two certified monitoring facilities near Tsumeb that contribute to the international system used to detect possible nuclear explosions.
Previous large-scale integrated field exercises were conducted in Kazakhstan in 2008 and Jordan in 2014, making the Namibian event the third of its kind.
Strengthening International Cooperation
The exercise provides an opportunity for countries to assess the readiness of international inspection teams and identify areas for improvement. It also reinforces cooperation in monitoring compliance with nuclear-test restrictions.
The CTBT has not yet entered into force, as ratification by all 44 states listed in its Annex 2 remains necessary. Nevertheless, the CTBTO continues developing the technical and operational capabilities required to implement the treaty once it becomes legally effective.
IFE26 places Namibia at the centre of international efforts to strengthen nuclear verification and demonstrates the importance of cooperation in preventing nuclear testing and promoting global security.
