Underwater Mines - Past, Present and Future
UNDERWATER MINES - PAST, PRESENT AND FUTURE Prof. S.Veerabhadraiah1, Dr. M.Purnachandra Rao2 1Department of Electronics and Communication Engineering, Raghu Engineering College, Visakhapatnam, Andhra Pradesh, (India) 2Professor of Physics, Head, Department of Systems Design, Andhra University, Visakhapatnam, Andhra Pradesh, (India) ABSTRACT Some examples of past, present and future mines available in the world are initially covered in this paper. This paper makes an assessment of present day underwater Mines technology for various applications in the area of defensive as well as offensive mining. The capabilities of underwater mines namely, operating as automatic sentinels in deep waters and easy deployment for offensive applications as well, meeting the future needs of naval task forces have also been covered in this paper. Finally the limitations of past and present mines are identified and the solutions to overcome these limitations so as to develop a state of the art mine are suggested towards the end of this paper. Keywords: Automatic Sentinels, Contact Mines, Influence Mines, Underwater Mine, World War I. I. INTRODUCTION A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, an enemy vessel. Naval mines can be used offensively—to hamper enemy shipping movements or lock vessels into a harbour; or defensively—to protect friendly vessels and create "safe" zones. The Sea Mine which was earlier thought to be a poor nation‘s weapon has attained a position of prime importance in the armories of many navies of the world. -

Assessing the Undersea Balance Between the US and China
SSP Working Paper February, 2011 Assessing the Undersea Balance Between the U.S. and China Owen R. Cote Jr. 1 Assessing the Undersea Balance Between the U.S. and China Owen R. Cote Jr. This paper will assess the undersea balance between the U.S. and China by comparing their relative abilities to accomplish their respective undersea warfare objectives. I will assess both the current balance, and how it might evolve in the future. In the latter case, I will focus on opportunities each side will have to adopt competitive strategies, or strategies designed to exploit its unique strengths or its opponent‟s weaknesses in ways that create favorable asymmetries in the resources that must be committed to accomplish particular missions. Defining the Undersea Balance Naval warfare is at bottom a contest over who will be able to use the seas, how, where, and when. Traditionally, it boiled down to the fate of surface ships carrying civilian or military cargo between ports, or sea lines of communication (SLOCs). One was either trying to assure SLOCs, deny them to one‟s opponent(s), or both. And for stretches of time and in certain areas the balance could be such that SLOCs were denied to both parties to the conflict. Thus naval operations occurred in only two dimensions and tended to unfold in almost complete operational and tactical isolation from events ashore and vice versa.1 The twentieth century saw submarines, aircraft, and earth orbiting satellites add a vertical dimension to naval warfare, and it also saw the obliteration of the coastline principle. -
The Next Dreadnought Revolution
THE NEXT DREADNOUGHT REVOLUTION BY DAVID MURRIN 15TH MARCH 2021 WWW.DAVIDMURRIN.CO.UK PART 1: CURRENT DESIGN TRENDS AND LIMITATIONS THE NEXT DREADNOUGHT REVOLUTION THE NEXT DREADNOUGHT REVOLUTION HISTORY DECODED TO INFORM THE FUTURE PART 1: CURRENT DESIGN TRENDS AND LIMITATIONS BY ANALYSING PAST PATTERNS WE CAN PREDICT FORTHCOMING EVENTS AND TRENDS 1.0 TIME FOR A NEW DREADNOUGHT-TYPE INNOVATION IN WARSHIP DESIGN In a time when battleships usually took several years to build, the construction and launch in 1906 of HMS Dreadnought in less than 12 months was a demonstration of British military intention and industrial might. But most critically, her all big gun design and steam turbines made every ship built before that point obsolete. The geostrategic consequences were enormous as it gave Germany a window to attempt to challenge for control of the world’s oceans and accelerated the British-German naval arms’ race to astronomical levels. Today we are witnessing a new and fourth great industrial arms’ race, catalysed by China’s hegemonic ambitions as it seeks to outbuild America and its allies to create a blue-water navy that can dominate the world’s oceans. In this similar environment, perhaps it is time to consider the emergence of a new class of Dreadnought destroyers, which I have named Dominators, that can control large areas of ocean both below and above it. 1.1 DEDICATED MISSION DESTROYERS AND FRIGATES This ship design concept of dedicated mission escorts is favoured by all European navies and the Royal Navy is an excellent specific example of using this concept in its escort fleet. -

Navy Ship Propulsion Technologies: Options for Reducing Oil Use — Background for Congress
Order Code RL33360 CRS Report for Congress Received through the CRS Web Navy Ship Propulsion Technologies: Options for Reducing Oil Use — Background for Congress April 12, 2006 Ronald O’Rourke Specialist in National Defense Foreign Affairs, Defense, and Trade Division Congressional Research Service ˜ The Library of Congress Navy Ship Propulsion Technologies: Options for Reducing Oil Use — Background for Congress Summary General strategies for reducing the Navy’s dependence on oil for its ships include reducing energy use on Navy ships; shifting to alternative hydrocarbon fuels; shifting to a greater reliance on nuclear propulsion; and making use of sail and solar power. Reducing energy use on Navy ships. A 2001 report by the Defense Science Board (DSB) stated that fuel efficiency has not been given a high priority in future system design. A 2001 study for the Navy by the Rocky Mountain Institute concluded that fitting a Navy cruiser with more energy-efficient electrical equipment could reduce the ship’s fuel use by 10% to 25%. The Navy has installed fuel-saving bulbous bows on certain ships, but might be able to install them on others. The Navy has installed fuel-saving stern flaps on many of its ships. Ship fuel use could be reduced by shifting from simple-cycle gas turbines to other turbine designs such as an intercooled recuperated (ICR) gas turbine. Shifting from mechanical-drive to integrated electric-drive propulsion can reduce a ship’s fuel use by 10% to 25%, and some Navy ships, such as TAKE-1 class cargo ships and DD(X) destroyers, are to use integrated electric drive. -
