Abstract:

India's two island territories; Andaman and Nicobar Islands in the Bay of Bengal and the Lakshadweep Islands in the Arabian Sea are at considerable distances from mainland and straddling some of the most critical international sea lanes of communication (ISLs) of the world. Their location and distance from India reinforce their criticality to India's security. Further, along with protecting India's territories, diaspora, and interests, India's defense forces may need to render assistance to countries that are crucial to India's strategic and economic wellbeing and also to further India's diplomatic foot print as directed by the government. There is thus a requirement to study the future of amphibious operations in the Indian context for furtherance of its national security objective. The article looks at the historical background of amphibious operations and future of joint amphibious operations in the Indian context to determine if the creation of an amphibious task force for India is an imperative given India’s centrality in the IOR. It argues that an amphibious capability that is maintained at a high state of operational readiness will provide India a high degree of strategic deterrence. This capability would also have the inherent ability to graduate from a threat in being to intervention, should the situation so require at short notice. Further, jointness is in the very nature of amphibious operations and hence the three Services need to synergize their actions and achieve results in the true spirit of jointness.

Abstract:

The U.S. Marine Corps spent the years between the world wars developing a doctrine of opposed landings from the sea in an arena where the ocean provided the only maneuver space, but the opposed amphibious operation is not the province of ocean-borne amphibious assaults alone. The land-water interface impacts warfare well inland from the coast, and much can be learned from the application of riverine and lacustrine amphibious assaults found in history. One such example is the siege of Enniskillen Castle in Ireland in 1594. English operations at Enniskillen demonstrated the value of coordinated waterborne and land-based forces at the tactical level. Considering English lacustrine operations in the Irish Nine Years’ War (1593–1603) and U.S. riverine warfare experiences in the American Civil War and Vietnam War can inform Marine planners as they develop the tactics, techniques, and procedures of the Marine Littoral Regiments.

Abstract:

The War of the Pacific (1879–84) showcases the development of amphibious warfare during a period of industrialization and technological flux. Historians have traditionally framed Chilean victory in the war as a function of seapower: naval superiority from which victory on land followed as a result. This view underestimates the complex and reciprocal interplay of amphibious and naval operations throughout the conflict. The war can be better understood as a campaign of port hopping, enabled by maritime capacity and naval power, but reliant on amphibious elements to achieve political results and sustain Chilean sea control. In exploring the relationship(s) between amphibious and naval operations in the War of the Pacific, this article historicizes the emergence of modern amphibious warfare as a component of seapower in the industrial era.

Abstract:

To determine the ideal landing beaches in amphibious operations must meet the requirements / criteria that have been determined, because it serves as an important component in the choice of landing beaches. The criteria include the type of beach, gradient beach, the basic material of beach, long beach landings, the type of breaking waves, tide, the kind of obstacles beach, ocean currents, the field behind the beach, the reference point mark landing beaches and access to the exit / entrance beach , In determining the selection of the landing beaches Marine / Navy had not done the calculation / mathematical model and not using a scientific method, such instances it is necessary to make a decision-making model in the case of election of the landing beaches in amphibious operations exercise. This study aims to determine the location of the landing beachesusing Fuzzy MCDM. The use of this method is the solution to produce a more objective group decision in the selection of an amphibious landing beach which data are accurate and reliable to help solve problems that are multi-criteria. There are 11 (eleven) criteria and 4 (four) alternatives identified in this study. Of the 11 criteria which have the highest weighting criteria for the alternative chosen in the first rank third alternative, namely PPD 3. Keywords: Amphibious Operations, Fuzzy MCDM, Criteria and Alternatives.

Abstract:

The amphibious invasions of Sicily, Salerno, and Normandy all made ample use of US Navy landing pontoons. The simple steel box pontoons were the brainchild of civil engineer Captain John N. Laycock, who developed and perfected his inventive design on the eve of American entry into World War II. Once in the conflict, a Royal Navy reserve officer assigned to Combined Operations Headquarters, Captain Thomas A. Hussey, conceptualized innovative uses for the American pontoons for offensive amphibious operations. Working together, these men developed pontoon causeways and massive lighterage barges which ensured logistical success in the invasions of German-occupied Europe. Les invasions amphibies de la Sicile, de Salerne et de la Normandie ont toutes fait appel aux pontons de débarquement de la Marine américaine. Les simples pontons flottants en acier ont été créés par le capitaine John N. Laycock, ingénieur civil, qui a développé et perfectionné sa conception géniale à la veille de l’entrée des États-Unis dans la Seconde Guerre mondiale. Une fois le conflit déclenché, le capitaine Thomas A. Hussey, officier de réserve de la Marine royale affecté au quartier général des opérations combinées, a mis au point des utilisations novatrices des pontons américains pour les opérations amphibies offensives. La collaboration de ces deux hommes a permis de développer des chaussées de pontons et d’énormes barges de chalandage qui ont assuré le succès logistique des invasions de l’Europe occupée par les Allemands.

Abstract:

Amphibious buses are extensively used worldwide for transporting people to and from tourist attractions across water and land. Although numerous studies on self-driving technologies have been reported, research on the automatic operation and navigation of an amphibious vehicle has been sparse; moreover, owing to the size of the amphibious vehicles, automatic transport of multiple people is not possible. Therefore, in this study, we attempted to realize unmanned operation of a sightseeing amphibious bus for 45 passengers. The bus was outfitted with a by-wire system. On the vessel side, an actuator, similar to that used in JOY cars, was installed to turn the captain’s steering wheel. We also developed a software for the automatic operation and navigation of the bus. The relationship between the car’s steering-wheel angle and the front-tire angles is linear, whereas that between the captain’s steering-wheel angle and the vessel’s rudder-plate angle is not (and was approximated with a sixth-order polynomial). Furthermore, Autoware—a leading autonomous-driving software utilizing model-based predictive control algorithms to control the steering wheel of automobiles—was employed in this work. These algorithms were altered using Nomoto’s KT vessel model equation to improve the accuracy of vessel-path tracking. To the best of our knowledge, till date, no studies have documented the functioning of self-driving vessels using predictive controls based on Nomoto’s KT vessel model equation. In accordance with the vessel navigation rules based on the Autoware obstacle avoidance logic, LiDAR, cameras, and sonars were employed to detect obstructions and give-way paths. Thus, we successfully demonstrated the working of world's first self-driving amphibious bus, with automated controls for entering/exiting water and during give-way operations.

Abstract:

High vehicle growth in Jakarta is not balanced with traffic growth, the level of congestion in Jakarta continues to increase every year. To overcome this congestion, innovation is needed to utilize the river as a means of public transportation. The amphibious bus is an alternative public transportation option in the Jabodetabek area to break congestion. The amphibious bus design must be supported by a propulsion system that can operate on land and water. The amphibious bus propulsion system is a must, according to river conditions and operational requirements. The selection of the drive system is carried out by means of analysis The driving criteria factors needed according to the specifications of the amphibious bus are power, efficiency, size, cost, and maneuverability. These criteria become indicators in determining the type of mover. This study aims to select the prime mover system based on criteria and specification requirements. The selection uses the process hierarchy analysis (AHP) method by giving weight to the criteria for each driver, and type of mover in the water, namely waterjets, azimuth-podded, Paddle Wheels, Cycloidal Propellers and propulsion on land diesel engines, gasoline engines, and electric engines. The results showed that the order of the propulsion selection criteria was propulsion power being the top priority, followed by maneuverability, energy efficiency, cost, operational and investment, and propulsion size and weight. The results of the AHP show that the main options are propulsion systems in water, namely waterjets and diesel engine propulsion systems on land. System Water Jet has a propulsion power of 1000 kW, has high maneuverability, energy efficiency of 85%, and a maximum speed of 60 Km/hour so it can meet the specifications of an amphibious bus drive. For operations on land, the main choice of propulsion system for amphibious buses is a diesel engine with a power of 250 HP and 800 Nm of torque providing strong torque and a wide cruising range. This system has a range of up to 800 km, a maximum speed of 120 km/h, and exhaust emissions of Euro 5.

Abstract:

ABSTRACT Determination of the landing beach becomes a must for the Marine Forces of the Indonesian Navy as an element of the landing forces in order to carry out the task of amphibious operations in particular to determine the ideal landing beach location for the successful implementation of the task. Requirements on the determination of ideal landing beaches should be in accordance with predetermined parameters and serve as an important component in determining the weighting value of landing beach selection criteria. This study aims to determine the location of landing beaches by using the Preference Ranking Method Method of Organization for Enrichment Evaluation (PROMETHEE) combined into the Borda method. The research stages started from determining the value of criterion preferences to the landing beach alternative options analyzed by PROMETHEE method then processed again in Borda method. The PROMETHEE method is used to analyze individual decisions of decision makers, while the Borda method is used to manage group decisions from the PROMETHEE method of ranking. The use of both methods is a solution to generate more objective group decisions so as to obtain a ranking result against the selection of logical amphibious landing beaches and have an objective value in accordance with accurate data and greatly assist decision-makers to solve multi-criteria problems. From the results of this study can be seen that the location of the selected beach is the most feasible to serve as the location of landing beaches in amphibious operations is Beach 3 with a weighted value of 0.389.

Abstract:

During the years of peace between the First and Second World Wars, it is clear that Navy and Marine Corps planners failed to sufficiently address several problems that would confront American forces in the looming conflict with Japan. Of these, one of the greatest omissions concerned the application of naval and aerial fires in support of an amphibious landing. Though American officers recognized and resolved concerns over landing craft, logistics, casualty evacuation procedures, communications, and much more, planners failed to adequately address the difficulties of controlling and coordinating supporting firepower in a triphibious operation. The 1934 Tentative Manual for Landing Operations highlighted the individual roles of naval gunfire and air support without confronting the more general coordination of land, sea, and air efforts, and it minimized the importance of flexibility and continuous coverage in amphibious fire support.

Abstract:

The introduction into service of the Westland manufactured Apache AH Mk1 has coincided with a thrust within the UK armed services for a greater emphasis on amphibious operations within the littoral environment. From this background has emerged a requirement for an embarked, attack helicopter capability, for which the Apache AH Mk1 has been earmarked. However, this helicopter being, by design, optimized for the battlefield environment, cannot be presumed to adapt to the naval environment without presenting certain challenges. This article describes how Westland Helicopters Ltd has sought to determine the feasibility of conducting embarked operations with Apache AH Mk1 by deriving limits to be respected during Ship Helicopter Operating Limits (SHOL) trials using a variety of analytical methods. Aspects of operation considered include aircraft lashing, landing, stability on deck with rotors running or stationary and when being towed, rotor engagement and disengagement, ground resonance, and main rotor spreading and folding. The article considers further aspects of importance to embarked operations and summarizes the trials process that results in an operational envelope for service use. It concludes that a practical operating envelope can be achieved, anticipates a successful outcome for the SHOL trials, and includes a projection for future activities to enhance the aircraft's maritime operational capabilities.

Abstract:

Major Joseph DiDomenico’s study of U.S. Army influence on U.S. Marine Corps tank doctrine appeared in the Summer 2018 issue of this journal, titled “The U.S. Army’s Influence on Marine Corps Tank Doctrine.” Mobilizing an impressive array of primary and secondary sources, DiDomenico laid considerable credit for the Corps’ improvements to its nascent World War II tank and amphibious tractor doctrine on the Army’s Armor School at Fort Knox as well as the improved Army doctrinal publications that had emerged by 1944. Major DiDomenico excoriated the Marine Corps’ neglect of “critical vulnerabilities for armor supporting amphibious operations.” The benchmark for Marine Corps tank doctrine’s failures to “synthesize” Army tank doctrine for Marine Corps missions is unsurprisingly the Battle of Tarawa. According to DiDomenico, the failures registered at Tarawa “indicated an institutional ignorance in the operational art of combined arms.” This article presents some common misconceptions of Marine Corps tank policy and doctrine and aims to correct those misconceptions.

Abstract:

Amphibious (air and water) drones, capable of both aerial and aquatic operations, have the potential to provide valuable drone applications in aquatic environments. However, the limited range of wireless data transmission caused by the low antenna height on water and reflection from the water surface (e.g., 45 m for vertical half-wave dipole antennas with the XBee S2CTM, estimated using the two-ray ground reflection model) persists as a formidable challenge for amphibious systems. To overcome this difficulty, we developed a wireless data relay system for amphibious drones using the mesh-type networking functions of the XBeeTM. We then conducted field tests of the developed system in a large marsh pond to provide experimental evidence of the efficiency of the multiple-drone network in amphibious settings. In these tests, hovering relaying over water was attempted for extension and bypassing obstacles using the XBee S2CTM (6.3 mW, 2.4 GHz). During testing, the hovering drone (<10 m height from the drone controller) successfully relayed water quality data from the transmitter to the receiver located approximately 757 m away, but shoreline vegetation decreased the reachable distance. A bypassing relay test for vegetation indicated the need to confirm a connected path formed by pair(s) of mutually observable drones.

Abstract:

Unmanned aerial vehicles (UAVs) have gained a lot of attention in recent times due to its versatility in deployment for multifaceted operations. The development of amphibious UAVs with inculcating the features of hovercraft and multi-rotor has tremendous impact on military, naval and coastal guard applications. Stability and performance of this kind of vehicle highly depend on aerodynamic interaction of multirotor with respect to various wind conditions. The present study focuses on performing computational fluid dynamic (CFD) analysis on examining the vortex formation, turbulent regimes, wake region, tip vortex formulation and ground effect.Preliminary flow analysis is performed to determine the angle of attack (AoA) and wind speed on which minimal drag is experienced by the amphibious structure. Further, analysis conducted through varying the relative velocity of the vehicle and changing the speed of the propellers. The pressure distribution across the fuselage and rotor surface predicted the stability of the vehicle. The ground effect is examined through varying the clearance between the vehicle and ground surface with respect to a multiplicity of rotor diameter. CFD analysis results suggested that at 5° AoA and 8.3 m/sec the designed amphibious vehicle yielded superior performance characteristics and stability.

Abstract:

During the American Civil War, U.S. Marines rarely engaged in land operations and even more rarely conducted land-based or amphibious operations involving more than one company. The Marine Corps’ lackluster battlefield performance ashore during the Civil War is best understood by examining their poor organization in officer selection, recruiting and retention, ad hoc formations larger than company size, limited collective tactical training, and experience in large-scale ground combat. The focus of this study is on large-scale Marine land operations, involving battalion-size elements assembled on an ad hoc basis and led by either U.S. Navy officers or U.S. Army officers, to analyze Marines’ battlefield performance ashore.

Abstract:

A mobile breakwater may be defined as a structure or device which combines the ability to appreciably reduce the height of ocean waves in its lee with a degree of mobility sufficient to permit its ready transportation for considerable distances and its speedy installation when arrived at the site. Such a device would find application wherever wave protection is necessary for but limited periods, as in offshore drilling operations, or where an installation is required to be completed in a very short time, as in amphibious military operations.

Abstract:

The Frogman Forces Command or Kopaska (Komando Pasukan Katak) is one of the special forces owned by the Indonesian Navy (TNI AL). Kopaska unit often carries out covert operations such as Amphibious Operations, Special Operations, and other supports to expedite Indonesian Navy operations. To support the implementation of these tasks, the Kopaska unit needs to be equipped with special equipment to carry out operational tasks. Currently, the Kopaska unit does not yet have a weapon mount that can be controlled remotely. This study proposes a multivariance weapon wireless system control that is designed to be used remotely by using a mobile application through the internet. A Multivariance Mount Weapon Wireless System Control was designed using the Kansei Engineering method to provide alternative tools to support Kopaska tasks more effectively and efficiently and be able to minimize material and personnel losses. The average value of the level of user satisfaction with the tool design has reached a fairly good position, namely 3.17 from the initial value of 1.36 (scale 1 to 4), so this new product is ready as an alternative to be produced.

Abstract:

The amphibious robot, which has the capability of multi-mode motion, can maneuver diverse environments with high mobility and adaptability. These are employed in the area of reconnaissance, search and rescue operations, and monitoring. The existing amphibious robots have lower maneuverability over the crawling period on uneven and slope surfaces on the land. In this paper, a kinematic model of the amphibious robot based on virtual prototyping is designed for multi-mode locomotion. ADAMS (Automated dynamic analysis of mechanical systems) is a multi-body dynamic solver adopted to build the simulation model for the robot. The novel amphibious robot employs a Rockerbogie mechanism equipped with wheel paddles. The locomotion analysis on land involves straight-going and obstacle negotiation, which is simulated using ADAMS. The simulation analysis result demonstrates increased maneuverability, achieving a robot's velocity of 1.6 m/s. Normal forces on the front and rear wheels show equal load distribution, contributing more to the robot’s equilibrium over uneven terrain. The simulation result reflects the accurate kinematic characteristics of the amphibious robot and provides a theoretical basis for developing an algorithm for robot motion control and optimization. Further, this research will concentrate on the kinematic simulation maneuvering in water mode with the wheel paddle.

Abstract:

Unmanned aerial vehicles (UAVs) have gained significant attention in recent times due to their suitability for a wide variety of civil, military, and societal missions. Development of an unmanned amphibious vehicle integrating the features of a multi-rotor UAV and a hovercraft is the focus of the present study. Components and subsystems of the amphibious vehicle are developed with due consideration for aerodynamic, structural, and environmental aspects. Finite element analysis (FEA) on static thrust conditions and skirt pressure are performed to evaluate the strength of the structure. For diverse wind conditions and angles of attack (AOA), computational fluid dynamic (CFD) analysis is carried out to assess the effect of drag and suitable design modification is suggested. A prototype is built with a 7 kg payload capacity and successfully tested for stable operations in flight and water-borne modes. Internet of things (IoT) based water quality measurement is performed in a typical lake and water quality is measured using pH, dissolved oxygen (DO), turbidity, and electrical conductivity (EC) sensors. The developed vehicle is expected to meet functional requirements of disaster missions catering to the water quality monitoring of large water bodies.

Abstract:

Abstract The Ultra Heavy-lift Amphibious Connector can be used for sea and land operations. When the amphibious connector opens the bow door, it will inevitably suffer from the combined action of wind, waves, currents, and other factors, resulting in the slamming of the wave on the hatch and various landing ship hull movements in the process. Due to the complexity of the actual UHAC model, in order to save computing resources, this paper selects the external load on the UAHC hatch when it is operated in water when the door is closed. The effects of crest height, draught, and focus position on UHAC slamming under the action of regular waves and freak waves were analyzed. Based on the viscous flow theory, the CFD commercial software FLUENT is used to simulate the interaction between the reduction of regular waves and floating structures. The simulation results are compared with the experimental results to verify the feasibility of the proposed method. Since the published UHAC data cannot be found in the network environment, this paper draws the UHAC based on the only data on the Internet and studies the slamming load of the wave on the UHAC on this basis.

Abstract:

As a result of wartime research on ocean surface waves a method has been available since 1943 for the prediction of wave characteristics of interest to engineers (O'Brien and Johnson, 1947). The initial stimulus for the development came during the planning of the invasion of North Africa, and the methods subsequently devised were later used in a number of amphibious operations (Bates, 1949). The same techniques have found useful peacetime application in problems connected with coastal engineering. Much of the application to date has consisted in applying wave prediction techniques to historical rather than current meteorological data, hence the term "wave hindcasting."

Abstract:

AbstractOver the past century trauma care within the Royal Navy (RN) has evolved; wartime experiences and military medical research have combined to allow signifi cant improvement in the care of casualties. This article describes the key maritime and amphibious operations that have seen the Royal Navy Medical Service (RNMS) deliver high levels of support to wherever the Naval Service has deployed in the last 100 years. Key advancements in which progress has led to improved outcomes for injured personnel are highlighted – the control and treatment of blood loss, wound care, and the prevention and management of organ failure with optimal resuscitation.Historians often point out how slowly military medicine progressed for the fi rst few thousand years of its recorded history, and how quickly it has progressed in the last century. This refl ective article will show how the RNMS has been an integral part of that story, and how the lessons learnt by our predecessors have shaped our modern day doctrine surrounding trauma care.

Abstract:

The provision of naval gunfire support was an important aspect of the Falklands War. By the end of the 1970s, naval gunfire support appeared to be doomed, but its vital role during the Falklands War led to a timely reappraisal. Indeed, the use of naval gunfire support during the Iraq War in 2003 and the conflict in Libya in 2011 vindicated the revival of interest in the capability. The Falklands War provided a number of valuable lessons about the role and significance of naval gunfire support, particularly during amphibious and expeditionary operations. With the threat of defence cuts ever-present, it is important that those lessons are not forgotten.

Abstract:

To address the issue of current garbage cleanup vessels being limited to performing garbage cleaning operations in the ocean, without the capability of transferring the garbage from the ocean to the land, this paper presents a spiral-propulsion amphibious intelligent robot for land garbage cleaning and sea garbage cleaning. The design solution is as follows. A mechanical structure based on a spiral drum is proposed. The interior of the spiral drum is hollow, providing buoyancy, allowing the robot to travel both on marshy, tidal flats and on the water surface, in conjunction with underwater thrusters. Additionally, a mechanical-arm shovel is designed, which achieves two-degrees-of-freedom movement through a spiral spline guide and servo, facilitating garbage collection. Our experimental results demonstrated that the robot exhibits excellent maneuverability in marine environments and on beach, marsh, and tidal flat areas, and that it collects garbage effectively.

Abstract:

Military deception is an action executed to deliberately mislead enemy’s decision by deceiving friendly forces intention. In the lessons learned from war history, deception appears to be a critical factor in the battlefield for successful operations. As training using war-game simulation is growing more important, it is become necessary to implement military deception in war-game model. However, there is no logics or rules proven to be effective for CGF(Computer Generated Forces) to conduct deception behavior automatically. In this study, we investigate methodologies for CGF to learn and conduct military deception using Reinforcement Learning. The key idea of the research is to define a new criterion called a “deception index” which defines how agent learn the action of deception considering both their own combat objectives and deception objectives. We choose Korea Marine Corps Amphibious Demonstrations to show applicability of our methods. The study has an unique contribution as the first research that describes method of implementing deception behavior.

Abstract:

Maritime unmanned systems (MUS) have gained widespread usage in a diverse range of hydrographic survey activities, including harbor/port surveys, beach and coastline monitoring, environmental assessment, and military operations. The present article explains a validated, rapid, and reliable technique for processing hydrographic data that was obtained via an autonomous hydrographic survey, and which was executed by a prototype unmanned surface vessel (USV) belonging to the Unmanned Survey Solutions (USS) corporation. The experimentation was part of the annual Multinational Exercise Robotic Experimentation and Prototyping that was augmented by Maritime Unmanned Systems 22 (REPMUS22), which was held in the national waters of Portugal. The main objective of this experimentation was to assess the underwater environment over an ocean beach for an amphibious landing exercise. Moreover, the integration of the multibeam system with the autonomous prototype vessel was assessed. A short comparison between the USV survey and a traditional vessel multibeam survey is presented, whereby the advantages of performing an autonomous survey operation near the coastline is emphasized. A correlation between a known multibeam processing technique and the dissemination of a rapid but consistent product for operational use is described, highlighting the applicability of the technique for the data collected from small experimental platforms. Moreover, this study outlines the relationship between the particular errors observed in autonomous small vehicles and in conventional data processing methods. The resultant cartographic outputs from the hydrographic survey are presented, emphasizing the specific inaccuracies within the raw data and the suitability of distinct hydrographic products for various user domains.

Abstract:

Much has been written of renewed great power competition and the characteristics of a potential armed conflict with the People’s Republic of China. This article surveys the strategic environment and the features of the current military strategies, detailing how such a conflict might be waged. In preparation for a potential conflict with China in which defense of the first island chain is required, the Joint force, and in particular the U.S. Navy and Marine Corps, have invested heavily in technology intended for amphibious expeditionary operations. However, most of the investment has centered on intricate and expensive aviation technology. Meanwhile, surface expeditionary technology has continued to age and now significantly lags its aviation counterparts such as the MV-22 Osprey and Lockheed Martin F-35 Lightning II. As a result, a strategic gap in capabilities has emerged that could dramatically impact the ability to execute an island-defense strategy.

Jaime Miguel de Guzmán-Dávalos y Spínola (1690-1767) was one of the most prestigious soldiers of the Enlightenment. He wrote Máximas para la Guerra, a book of unquestionable value that was published upon his death. In this article, paraphrasing the words of the author mentioned in its title, we aim at studying the precepts of the renowned scientist on amphibious warfare to which he devoted a chapter of his work. Having in mind its unquestionable quality, and being far from the hagiographic idolatry, we are going to run its critical evaluation. Disembarking troops is one of the most complex military operations ever. Our study contains lessons that we consider to be most valuable as well as decisions that we view as not so beneficial. In addition to that we also tackle the aspects that in our opinion could have been presented and analysed by the author and were not included.
