Russia is developing two new types of nuclear submarines to replace its Project 949A Oscar-class and Project 945 Sierra-class vessels. The new vessels are a generation beyond Russia’s Project 955 Borei-class ballistic missile submarine and Project 855M Yasen-class guided-missile submarines, which are originally late Soviet-era designs.

Understanding NATO’s Concept for Deterrence and Defense of the Euro-Atlantic Area

May 20, 2024 Katherine Kjellström Elgin, Sean Monaghan, Sara Bjerg Moller

NATO, the largest and most powerful military alliance in history, turned seventy-five in April. In July, the leaders of NATO will return to the city where its founding document, the Washington Treaty, was signed in 1949. Most people have heard of NATO. Fewer know its most important document is the Strategic Concept, which is updated every decade or so, and sets the Alliance’s strategy. An even smaller group know about NATO’s “Concept for Deterrence and Defence of the Euro-Atlantic Area.”

More of the Same? The Future of the Russian Military And Its Ability to Change

March 18, 2024 Katherine Kjellström Elgin

Assessing the type of threat that Russia is likely to pose in the aftermath of the war in Ukraine is a critical challenge for the United States and its allies. What will the Russian military look like in the future? Some argue that the Russian military will remain a significant threat – and perhaps become a very different and even more serious one. This argument holds that the Russian military will reconstitute in a relatively short time frame and may reform according to lessons learned during the war in Ukraine. Others argue that the Russian military will pose a far less formidable conventional threat going forward. Not only has the war against Ukraine exposed fundamental weaknesses in the Russian military, the argument goes, but Moscow’s ability to address those weaknesses will be limited by available manpower, sanctions, and export controls.

An Ongoing and Necessary Renaissance: NATO’s Nuclear Posture

January 25, 2024 Eric Edelman, Franklin C. Miller

President Putin’s nuclear saber-rattling while the war in Ukraine has raged, along with lurid nuclear threats by Russian officials and propagandists, have once again focused attention on NATO’s nuclear mission. As the alliance approaches a summit in Washington later this summer, it is an appropriate time to review its nuclear posture.

Strengthening the Phalanx: Layered, Comprehensive, and Distributed Air and Missile Defense in the Indo-Pacific

January 17, 2024 Carl Rehberg, Herbert Kemp

One of the most critical operational challenges the United States is likely to confront in a future conflict, particularly in the Indo-Pacific theater, is the threat of massed precision-guided air and missile attacks on overseas ports, bases, and other vital facilities. DoD has invested significant resources to defend against ballistic missile attacks on the United States, as well as its forward bases and forward-operating forces. However, it cannot still defeat large numbers of ballistic missiles, cruise missiles, and unmanned aerial systems.

Inconsistent Congress: Analysis of the 2024 Defense Budget Request

October 17, 2023 Travis Sharp

After increasing the Department of Defense (DoD) budget in real terms during seven of the past eight fiscal years, Congress has now pivoted toward restraining spending by passing the Fiscal Responsibility Act of 2023. Approved in early June as part of the debt ceiling deal, the law imposes a liberating limit on defense. It unshackles defense spending from parity with nondefense spending but still caps military budgets at or near current spending levels for the next two fiscal years while brandishing the threat of a lowered defense cap and potential sequestration if Congress delays in passing full-year appropriations for any budget account.
