Russia's Conventional Precision Strike Capabilities, Regional Crises, and Nuclear Thresholds

The potential for war between Russia and the West has returned after a long hiatus, despite the many effor ts of the United States and its NATO allies to remake the relationship with Russia by putting it on a much more cooperative footing. A central question for the West is what role nuclear escalation by Russia might play in such a confl ict. It is common today to hear Western experts argue that Russia’s nuclear threshold has fallen—and that it will rise again as Russia’s modernization of its general purpose forces plays out in coming years. A close examination of this topic points to a different set of conclusions. Russia’s nuclear threshold has not so much fallen as changed, becoming more fl uid and less predictable. The modernization that will matter to Russia’s future nuclear threshold is not the modernization of the general purpose forces but the newly diversifi ed strategic toolkit, which includes multiple new non-nuclear tools. Western deterrence strategies must adapt to a circumstance that appears somewhat similar to Cold War challenges but is in fact substantially different.

Complex Functional Materials

Complex functional materials are materials comprised of multiple components or building blocks that are integrated or chemically bound together to achieve a desired function or response. Soft materials, such as polymers, as well as structural properties at the mesoscale and micro-scale that control materials function are particularly emphasized in this area of leadership. Further, complex functional materials must generally be developed to satisfy multiple criteria essential to the overall application. Thus, this area of leadership supports applications that are aligned with all three Los Alamos National Laboratory mission areas of energy security, global security, and nuclear deterrence.

Radiological/Nuclear (RN) Terrorism: Global Assessment of Threat Intention Drivers.

There is a pressing need in international security policy to better understand the future landscape of radiological and nuclear (RN) dangers and how best to target resources to affect their reduction. The highly dynamic nature of the global geopolitical, social and technological environments means that ther e are many potential forces that might influence the magnitude of current RN dangers, especially those emanating from non-state actors like terrorists. These include: the spread of radical ideology, the growth of civilian nuclear energy in politically unstable regions of the world, the potential for increased nuclear proliferation in those regions, the continued dissemination of WMD information in open sources, and advances in technology that may facilitate VNSA violent non-state actor (VNSA) RN programs. Therefore, this study’s main purpose is to provide an overview of the high level future drivers of RN terrorism as they pertain to the motives and intentions1 of known and potential adversaries. A central approach of this study is to ask the question: Why have there not been more attempts to engage in RN terrorism and, particularly in the case of radiological terrorism, why have those attempts that have been made not been more successful? Once the probable factors that have curtailed the RN terrorist threat thus far have been identified, the study will consider whether there are extant and emerging drivers that might bring about changes in these mitigating factors over the next 10 years. Finally, the study attempts to assess the future dangers of RN terrorism based on these potential changes and what policy approaches can be implemented to reduce the threat, particularly the role of deterrence and dissuasion.

Nuclear Weapons Data Strategy

This document describes the data strategy for the Nuclear Weapons Program Management Unit (NW PMU), with emphasis on functions related to the product realization lifecycle. It describes a vision to more effectively value and utilize data as an asset: data often is our product, and when it isn't, our products are made possible only through the data produced and consumed throughout each product's lifecycle. True confidence in the nuclear deterrent requires a clear understanding of how our products perform against requirements; both in the near term as well as over long periods of time. Data is the foundation for this understanding, and as such is a key enabler of the success of the NW mission. This document defines principles that enable a "culture of care" around NW data and drive the specific approaches to create a data-centric environment that is sustainable, agile, and responsive to the needs of the NW mission. The strategy outlined within this document must guide the definition of a high-level roadmap to achieve this vision, which in turn will be supported by separate detailed implementation plans.

Implementing the Hedge Strategy in the 2018 Nuclear Posture Review

Maintaining stable and effective deterrence requires nuclear forces that are structured and postured to respond to potential futures challenges as well as deter today’s potential adversaries under present circumstances. The 2018 Nuclear Posture Review (NPR) establishes a strategy for hedging against uncertainty that prioritizes the ability to sustain five key force attributes in the face of technological or geopolitical challenges. Using these key attributes, one can analyze the current and planned U.S. nuclear force structures, as well as various alternatives that have or may be proposed. This analysis is based on the ability of force structures to provide key attributes and combinations of attributes, and their ability to preserve those attributes and combinations when potential challenges arise.

Examining Efficacy of Strategic Stability in South Asia: An Analysis

This paper highlights how, in the backdrop of prevalent tensions between India and Pakistan, deterrence stability is endangered even when overall strategic stability prevails. Unresolved legacy issues including an outstanding boundary dispute, conflict over Kashmir, and terrorism mar India-Pakistan relations. Variables undermining the prospects for long term peace, among others, include growing mutual mistrust, the proxy war that India believes is state perpetrated, increasing conventional asymmetry, rapid advancement in weapon technologies, growing size of nuclear arsenals, doctrinal mismatch and above all, bilateral gridlock in confidence building measures and arms control measures.

Advanced Simulation and Computing FY20 Implementation Plan (Rev. 0)

The Stockpile Stewardship Program (SSP) is an integrated technical program for maintaining the safety, surety, and reliability of the U.S. nuclear stockpile. The SSP incorporates nuclear test data, computational modeling and simulation, and experimental facilities to advance understanding of nuclear weapons. The suite of data analyzed comes from activities including stockpile surveillance, experimental research, and development and engineering programs. This integrated national program requires the continued use of experimental facilities and the computational capabilities to support the SSP missions. These component parts, in addition to an appropriately scaled production capability, enable the National Nuclear Security Administration (NNSA) to support stockpile requirements. The ultimate goal of the Stewardship Program, and thus the Advanced Simulation and Computing (ASC) Program, is to ensure that the U.S. maintains a safe, secure, and effective strategic deterrent.

Magnetic Smart Tags (MaST) for Arms Control and Treaty Verification

The ability to track nuclear material is a challenge for resiliency of complex systems, e.g., harsh environments. RF tags, frequently used in national security applications, cannot be used for technological, operational, or safety reasons. Magnetic Smart Tags (MaST) is a novel tag technology based on magnetoelastic sensing that circumvents these issues. This technology is enabled by a new, cost-effective, batch manufacturing electrochemical deposition (ECD) process. This new advancement in fabrication enables multi-frequency tags capable of providing millions of possible codes for tag identification unlike existing theft deterrent tags that can convey only a single bit of information. Magnetostrictive 70% Co: 30% Fe was developed as the base alloy comprising the magnetoelastic resonator transduction element. Saturation magnetostriction, λ S , has been externally measured by the Naval Research Laboratory to be as high as 78 ppm. Description of a novel MEMS variable capacitive test structure is described for future measurements of this parameter.

Artificial Intelligence, the Final Piece to the Counterforce Puzzle?

It is widely expected that artificial intelligence (AI) will disrupt and fundamentally transform many aspects of social, economic, and political life over the coming decades. As we are in the early stages of AI adoption in most fields, many discussions of its potential necessarily impact remain vague and superficial, including where national security is concerned. Nevertheless, some scholars have productively explored AI’s impact on the character of warfare, the balance of power among states, and human society itself. This article contributes to this growing body of literature by examining how this new technology might interact with one of the most prominent features of the post-World War II strategic environment: nuclear weapons. Specifically, it asks whether AI-driven improvements to intelligence, surveillance, and reconnaissance (ISR) capabilities, i.e., automated image recognition/computer vision, could enable an effective counterforce capability and thereby imperil nuclear deterrence and weaken first-strike stability. Since the advent of the nuclear age, analysts have been divided over the meaning of nuclear weapons for international politics. Proponents of the “nuclear revolution” argue that nuclear weapons, particularly a secure second-strike capability, which would allow a state to retaliate with nuclear force after suffering a first strike, satisfy a state’s security needs because they present a potential for unacceptable damage that would deter any potential challenger from even considering aggression. In their view, international politics in the shadow of nuclear weapons would be largely peaceful, competition would be relegated to the margins, and nuclear superiority would be meaningless. However, recent research suggests that this may not be the case. In fact, nuclear weapon states have sought to hold at risk the nuclear arsenals of their adversaries throughout the nuclear age. Still, no country has attacked another’s operational nuclear arsenal. That is because the requirements for a disarming strike are considerably higher than for damage limitation or retaliation against nuclear attack. A state trying to disarm its opponent would have to be certain to destroy, or at least disable, all of its adversary’s nuclear weapons. Even one operational nuclear warhead could inflict unacceptable damage in a retaliatory blow. The inability to be certain that a first strike could find and eliminate all enemy nuclear weapons has been the main roadblock for effective counterforce. As the number of battlefield sensors grows and ISR capabilities improve, however, this roadblock is crumbling. Some expect it to be fully overcome with the help of AI.

Scientific and Historic Impacts from the Manhattan Project [Slides]

The Manhattan Project (MP) was the international project that led to production of the first nuclear weapons. It opened up a new chapter in human history that we now call the atomic age. The MP is an example of living history where multiple generations continue to learn and evaluate the full magnitude of its history, science, technology, and deterrence and security implications throughout time. The idea to have a student symposium about the MP grew out of conversations with colleagues and students. The prevailing opinion was indeed that there is a growing interest in history, science, politics, and security implications of the MP. We thought it would be useful to keep the direct dialog and discussion going to allow younger generations the chance to formulate their own opinion. The scope of the symposium is large, covers multiple topics, and is impossible to cover in detail in one day. We are trying to embrace a very wide spectrum of questions. The world around us is evolving and it is important to present, as completely as possible, an arc of facts about the MP and what followed. Hence, we have presentations covering the MP and broad issues of the nuclear age from the initial stages of the MP in 1942 to modern day. I believe it is important to have a forum that enables better appreciation and understanding of the MP among younger generations. Our hope is that this symposium will strengthen the ongoing dialog and create an open student forum to hear and learn about the MP.
