مستخلص: Japanese Prime Minister Kishida Fumio is set to visit the United States in early April for a state visit and to hold talks with President Joe Biden. The visit comes at a challenging time for both leaders, as they have low public approval ratings at home. The summit will focus on "minilateralism," highlighting the significance of groupings like the Quad and AUKUS in countering China's growing influence in the Indo-Pacific region. Additionally, both leaders will aim to showcase their success in domestic job creation ahead of their crucial elections this year. [Extracted from the article]

مستخلص: The article discusses Russia's naval resurgence and the growing importance of undersea warfare, particularly in the Arctic. It is reported that Russia's advanced submarines has challenged Western navies, and the changing Arctic environment due to climate change has added complexity to anti-submarine warfare. It is further reported that NATO's Centre for Maritime Research and Experimentation (CMRE) is studying the impact of climate change on ASW in the Arctic.

الملخص (بالإنجليزية): Aiming at the main factors affecting the operational effect of anti-submarine assisted torpedo, the air and underwater trajectory models of anti-submarine assisted torpedo are established based on the analysis of its trajectory characteristics. According to the typical maneuver evasion style of enemy submarine, the simulation program was compiled according to the anti-submarine warfare process of anti-submarine assisted torpedo, and the influence of range, impact point deviation and active homing range on the hit probability of anti-submarine assisted torpedo was quantitatively analyzed. The results show that the analysis has a certain theoretical guiding significance for the simulation, test and training scheme of the anti-submarine assisted torpedo combat capability.

الوصف: The PLA Navy recognizes the importance of a robust anti-submarine warfare (ASW) system to counter adversaries seeking undersea asymmetric advantages, and its aviation component is a key part of that system. This report discusses the PLAN's efforts to improve its airborne ASW platforms and equipment and describes how PLAN-affiliated sources discuss the employment of those assets. The PLAN's significant buildup and growing employment of fixed-wing maritime patrol aircraft in recent years are key indicators of the importance it attaches to the airborne ASW mission set, as is its push to acquire improved sensors on both fixed and rotary wing ASW platforms. PLAN-affiliated authors show that its academic and operational components are coordinating to explore best practices and maximize the effectiveness of these assets across a wide array of ASW scenarios. ; https://digital-commons.usnwc.edu/cmsi-maritime-reports/1038/thumbnail.jpgTest

مستخلص: Japan has completed the development of the SH-60L Seahawk, a maritime patrol helicopter with anti-submarine warfare capabilities. The SH-60L is a successor to the SH-60K and features a new transmission, high-speed datalink, and ASW systems. The Japan Maritime Self-Defense Force has requested funds for the production of six SH-60L helicopters. North Macedonia has selected Leonardo to replace its Soviet-era helicopters, choosing the AW149 and AW169M models. The NATO Support and Procurement Agency has awarded Sikorsky a contract for preliminary research for the Next Generation Rotorcraft Capability program, and Bell and Leonardo are jointly evaluating the possibilities of a tiltrotor for the program. Safran Helicopter Engines plans to deliver 10,000 new engines over the next decade to meet the demand from the helicopter market. [Extracted from the article]

مستخلص: The Philippine and US militaries have begun their second round of maritime drills in the South China Sea, aimed at enhancing their interoperability. The drills include passing exercises, communication checks, joint patrols, and flight operations. Tensions between China and the Philippines have been escalating in recent months, with both countries asserting their claims in the disputed waters. Philippine President Ferdinand Marcos Jr. has strengthened defense ties with the US, Japan, and Australia in response to China's expansive claims. The drills signify the strengthening of the alliance between the Philippines and the US. [Extracted from the article]

الشركة/الكيان: GREAT Britain. Royal Navy

مستخلص: Submarines are pressing their way back to the top of the maritime agenda. To deal with the burgeoning submarine threat, the full spectrum approach to anti-submarine warfare has been developed. Its ten threads hope to defeat – as opposed to destroy – hostile submarines. This paper will explore the historical evidence surrounding the full spectrum approach. It will argue that the historical evidence for many of the threads is weak, but that when the fundamentals of submarine warfare are considered many of the lessons of WW1 and WW2 may still be relevant to today's practitioners.

مصطلحات موضوعية: *ASSET allocation, ANTI-submarine warfare, HIDDEN Markov models, NP-hard problems, EVOLUTIONARY algorithms

مستخلص: Anti-submarine warfare (ASW) missions are the linchpin of maritime operations involving effective allocation and path planning of scarce assets to search for, detect, classify, track, and prosecute hostile submarines within a dynamic and uncertain mission environment. Motivated by the need to assist ASW commanders to make better decisions within an evolving mission context, we investigate a moving target search problem with multiple searchers and develop a context-driven decision support tool for the ASW mission planning problem. Given the spatial probability distribution of a target submarine, sensor detection probability surfaces from meteorological and oceanographic products, and the risk to the fleet as a function of distance of the target from the fleet, we model and formulate the ASW asset allocation and search path planning problem using a hidden Markov modeling framework. We propose a two phase approach to solve this NP-hard problem. In phase I, we partition the geographic area, satisfying contiguity constraints, into search regions using an evolutionary algorithm (EA) coupled with a Voronoi tessellation approach, and allocate the assets to partitioned search areas using the auction algorithm. In phase II, we construct a dynamic search plan for each asset over the search interval using EA. We evaluate our approach via a hypothetical ASW scenario to monitor an enemy submarine in a geographic region via multiple assets. We compare our results to various search path planning strategies that, using the context-driven decision support tool developed here, revise the search regions at periodic intervals given a fixed total search time.
