Open Nuclear Network joins the European non-proliferation and disarmament network (EUNPD), a collection of think tanks combating weapons of mass destruction and their delivery systems.

The Democratic People's Republic of Korea launched at least two "super-large calibre" multiple rocket launcher rounds into the Sea of Japan or East Sea on 9 March 2020. It is the sixth confirmed test launch of the system, with a total of at least 12 such rockets having been launched since it was dev...

North Korea’s recent missile launch tests have nuclear weapons experts around the world on watch and weighing in on the tension unfolding across the Korean Peninsula.

ONN combines open source data technology with a multinational team of experienced analysts and researchers, and its expert coordination of a global Engagement Network of accomplished individuals who are well positioned to open doors for dialogue among global leaders.

Open Nuclear Network was officially launched today, a new non-aligned non-governmental organization with a mission to reduce the risk of nuclear weapons use in response to human or technical error, uncertainty or misdirection.

I study missiles and nuclear delivery systems to better understand capabilities and ways to build strong, verifiable agreement and reduce the risk of nuclear weapons systems.

I use open source data, statistics and machine learning to understand evolving trends related to nuclear risk reduction. Our current focus is the Korean Peninsula which, on a personal level, I obviously care deeply about.

My semi-scientific background is very helpful in understanding and analysing the technical developments of North Korea's nuclear program and I also bring an understanding of the global non-proliferation context.

Melissa Hanham joined other experts for a panel discussion to share her perspective on issues of nuclear risk reduction in the Hague.

Based on the limited information available, the projectiles appear to be the KN-24 - a solid-fuel, short-range ballistic missile - or a multiple rocket launch system, said Melissa Hanham, a weapons expert and Deputy Director of Open Nuclear Network.

ONN was featured in The Conversation.

“If you launch one or many of these at South Korea, you have between seconds and minutes to decide if this is a conventional attack, a nuclear attack or some other WMD payload,” said Melissa Hanham, deputy director of the Open Nuclear Network, a weapons expert specializing in the analysis of satelli...

"I believe U.S. President Donald Trump and [North Korean] Chairman Kim Jong Un share the need for a win on this," said Laura Rockwood, who worked for the IAEA for 28 years in several high-level positions and currently serves as the Director of Open Nuclear Network.

"We haven't seen any activity which would indicate that there's an impending test," said Melissa Hanham, an expert on open-source intelligence and director of the Datayo Project at the One Earth Future Foundation.

The weapon was likely a short-range rocket system, or something that was ground tested, said Melissa Hanham, a non-proliferation expert and Director of Open nuclear Network’s Datayo Project.
