Rise in SIPRI Top 100 arms sales revenue delayed by production challenges and backlog

On 4 December, SIPRI released its latest data on the revenues from sales of arms and military services by the 100 largest companies in the industry, which totalled $597 billion in 2022, 3.5 per cent less than 2021 in real terms, even as demand rose sharply. The decrease was chiefly the result of falling arms revenues among major companies in the United States. Revenues increased substantially in Asia and Oceania and the Middle East. Outstanding orders and a surge in new contracts suggest that global arms revenues could rise significantly in the next few years.

News item 2
Russia’s new budget law signals determination to see the war in Ukraine through, according to new SIPRI analysis

Russia’s military and war-related spending is set to rise sharply in 2024 under new federal budget plans for 2024–26 signed into law by President Vladimir Putin on 27 November. The plans suggest that the Russian government is committed to pursuing the war to a successful conclusion but are based on questionable economic assumptions, according to a new analysis. The report estimates that at 12 765 billion roubles (around US$140 billion), Russia’s planned military spending in 2024 would be 29 per cent higher in real terms than in 2023, representing 7.1 per cent of gross domestic product and 35 per cent of all government expenditure.

Commentary 1
More investment in nuclear deterrence will not make Europe safer

Russia’s invasion of Ukraine in February 2022 and the nuclear threats it has made since have driven a new wave of militarization in Europe. In addition to pushing Finland and Sweden to seek membership in the North Atlantic Treaty Organization (NATO), the perception of an increasingly unpredictable and revanchist Russia has led the alliance to boost its deterrence capabilities. These efforts have focused mainly on conventional forces, but arguments are currently also being made for strengthening nuclear deterrence. This essay takes issue with such proposals, arguing that NATO has no need to augment its already superior conventional forces by increasing reliance on weapons of mass destruction.

Small and micro launchers in the NewSpace era: New missile proliferation risks or more of the same?

The global growth of the NewSpace industry, the demand for launch capacity for small satellites and the desire to reduce launch costs are driving the development of small and micro launch vehicles by commercial providers. The dual-use nature of traditional space launch vehicle technology has always been a missile proliferation challenge. With the larger number and diversity of launch vehicle projects pursued by commercial providers in the NewSpace era, the extent of this challenge appears to be changing. This topical backgrounder seeks to create a better understanding of current trends in small and micro launchers and how they contribute to missile proliferation risks.

Another Budget for a Country at War: Military Expenditure in Russia’s Federal Budget for 2024 and Beyond

Russia’s war against Ukraine has been waged for over 650 days and has had a significant impact on the country’s economy and society. This SIPRI Insights Paper examines the new three-year Russian federal budget, which was signed into law at the end of November. It is based on a relatively optimistic economic forecast and is striking for the sharp increase in military spending planned for 2024. The budget indicates that the Russian government is firmly committed to pursuing the war to a successful conclusion, accepting that this will put pressure on social and economic spending.

Advancing the Role of the European Union in Promoting Global Cyber Stability

Cyber incidents affecting satellite and missile systems, whether caused by error or intent, extend beyond the Ukraine conflict. These disruptions pose risks to civilian and military operations, potentially triggering conventional or nuclear responses. Recognizing the centrality of this infrastructure, previous confidence-building measures (CBMs) inspired by cyber incidents offer insights. Building on SIPRI’s research, this paper maps such incidents and CBMs, offering takeaways to enhance predictability and stability in cyberspace.

This paper, published by SIPRI for the Stockholm Hub on Environment, Climate and Security, outlines broad, but critical, starting points for working towards a more comprehensive biosphere security research agenda. The interconnected nature of the security and biodiversity crises represents potential opportunities for tackling both issues in tandem. This requires the engagement of multiple academic disciplines and non-academic actors and must be oriented towards, and supported by, the policy world.
