Advances in nuclear weapon technologies from – and the corresponding evolution in the threat landscape posed by – non-allied nations over the past four years underscores the exigency of the United States (U.S) in updating its stated national security policies. Here we review and suggest options for the 2022 Nuclear Posture Review (NPR) regarding the low-yield submarine-launched cruise missile (SLCM-N) and submarine-launched ballistic missile (SLBM) programs. The 2018 NPR called for programmatic changes to counteract the evolving threat environment and allow for greater deterrence flexibility. These programs include modernization of existing technologies and creation of novel weapons systems. Of these changes, two new programs were started to develop low-yield, sea-based, non-strategic weapons. These options are designed to counter any perceived gaps in U.S. regional deterrence capabilities. We enumerate several policy options likely to be considered by the Biden White House. Our proposed solution calls for maintenance of the W76-2 program and the continuance of the low-yield SLCM-N program; we present our argument along the axes of technical and cost considerations, service system preferences, tailored response capabilities, ensured support and defense of our allies, and prevention of escalation to war.

In information war, the concept of “digital battlefield” is put forward, and battlefield meteorological and marine information has become an important part of digital battlefield. Based on the in-depth analysis of the impact of meteorological marine information on cruise missile, this paper puts forward the multi-dimensional demand analysis method of meteorological marine information supporting cruise missile combat application and the architecture design method based on MBSE, and gives the conceptual design framework of combat application system to provide information support for cruise missile combat application.

The capability of the first strike is crucial in the modern battlefield. An important parameter is the radar signature or Radar Cross Section (RCS) of a weapon system, such as a fighter aircraft, a warship, or a missile, affecting the range at which this weapon system would be detected as a target by an enemy radar. If the attacker is detected too late, there will be minimal time for the defender to react, possibly not sufficient to counter the threat. The RCS of a weapon system is considered generally as classified information. However, it can be measured at a suitable measurement test range, if that weapon system is available. Otherwise, it can be predicted with the help of computational electromagnetics. Concerning the second approach, the following procedure was recently proposed: construction of a three-dimensional model of a target, based on available images and any relevant data, and then computation of the target RCS, with the Physical Optics approximative method. In the present approach, this procedure is applied to an anti-ship cruise missile in order to compute its RCS. Finally, the expected detection range for various naval radars is calculated.

The modern “Anti-Access/Area Denial” A2/AD systems are defined as a combination of all possible measures that can limit the ability of a potential opponent to enter and occupy a given area (operational theatre). Their action relies, among others, on radio-electronic disruption of digital guidance systems, communication, command and control systems, shooting down long-range maneuvering missiles, drones, and aircraft. The primary assumption of the anti-access concept is to deprive the enemy of the possibility of entering a given operational area (A2 – Anti-Access) through long-range destruction and depriving them of freedom of action in that theatre (AD – Area-Denial) by medium and short-range weapons. The Surface-to-Air Missiles (SAM), Anti-Ship Ballistic Missiles (ASBM), and Anti-Ship Manoeuvring Cruise Missile (ASCM) are used to carry out A2/AD tasks. Field artillery has also been used recently, particularly the Long-Range Precision Fires (LRPF). The purpose of the article is to determine the chance of using field artillery against the A2/AD systems. According to the authors, the NATO forces will lose control in the air in the first period of the conventional conflict with an equivalent opponent, and its rapid recovery will be a priority. Field artillery, as a weapon with ever greater possibilities of precise and deep destruction, can become a decisive factor, allowing dominance of A2/AD systems and enabling the implementation of tasks of its air-force and army aviation, as well as ground forces.

Grid fins are normally placed at the rear end of cruise missiles, rockets and other ballistic devices to control their trajectory especially at the final stage of flight. These fins provided fine control of the pitch, yaw and other lateral movements, allowing for higher stability and accuracy of the cruise missiles. This project investigates computationally the relation between grid fins inner lattice structures dimensionless parameters and the fins aerodynamics drag coefficient. The project gathered data from 12 different fins by varying the parameters of its internal lattice structure such as thickness, width and chord at various angles of attack (0°, 20° and 40°). The freestream was set at a constant speed of 150 m/s that gives Reynolds number > 1.7 x 106 . The results were experimentally compared by using a re-scaled model of a single fin in a sub-sonic wind tunnel, achieving a difference in results of not exceeding 6%. The results obtained that as the width-chord ratio increases, the aerodynamics drag coefficient increases for fixed thickness-width ratio. The results also demonstrated that as the angle of attack increases, the aerodynamics drag increases. The thickness-width ratio has the larger impact on the aerodynamics drag. The results can be used to improve the design of guided cruise missiles.

With a focus on the strategic competition between the United States and Russia, this paper explores the prospects for the future of arms control under an intensifying nuclear security dilemma. The end of stability-enhancing agreements such as the INF Treaty and Open Skies has accelerated the arms race. What is the future of New START and are we likely to see any extension beyond 2021? The relationship between arms control and strategic stability is part of this evaluation, particularly with respect to how states view the concept framed within their national security interests. The provocative role that offensive – deterrence by denial – capabilities play in contributing to strategic instability is central to this study. This work looks particularly at new systems designed for asymmetric advantage, including those that can defeat strategic defences, such as longer-range cruise missiles and hypersonic vehicles. Under conditions of modernizations and upgrades to nuclear arsenals, including the entanglement of conventional and nuclear systems that can threaten a first strike, this work considers how a dialogue on limiting dangerous systems could be initiated between the US and Russia. Could New START be revised – or a new treaty established – to limit advances in cruise missile technology, hypersonics, missile defences, and tactical nuclear weapons?
