This book was released on 2015-05-14 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear powered submarines are most vulnerable to detection and attack while at periscope depth. Submarines also have specific communication and time requirements they have to meet and the primary method of transmitting and receiving data is via satellite, which requires the submarine to be at periscope depth. This means that in a command and control denied environment (C2DE), a submarine may be incapable of receiving orders or transmitting required reports. In order to meet its communications requirements, the submarine has to navigate outside of the denied environment, conduct all necessary satellite communications, and proceed back to the C2DE zone. Through great improvements in unmanned underwater vehicle (UUV) technology and the development of new line-of-sight rapid data transmission methods, submarines may be able to operate in C2DEs and conduct all necessary communications without ever going to periscope depth. This study analyzes different configurations for UUV and submarine interaction in a C2DE area using a series of models in the Map Aware Non- Uniform Automata (MANA) modeling environment. This analysis explores the value of several different UUV characteristics as well as undersea garage configurations in minimizing the time it takes for a submarine to conduct its communications, the latency of the data received, and the cost of construction for the system. The system as modeled shows that the combination of the UUV and blue-green laser can provide the submarine with service times comparable to the time it takes for a submarine to reach periscope depth and expected data latency of less than an hour.

Available in PDF, EPUB and Kindle. Book excerpt: Which military missions for unmanned undersea vehicles (UUVs) appear most promising to pursue in terms of military need, operational and technical risks, alternatives, and cost? To answer this question, the authors assess risks associated with using UUVs for advocated missions, identify non-UUV alternatives that may be more appropriate for such missions, and analyze potential costs associated with UUV development and use. They conclude that seven missions: mine countermeasures, deployment of leave-behind surveillance sensors or sensor arrays, near-land and harbor monitoring, oceanography, monitoring undersea infrastructure, anti-submarine warfare tracking, and inspection/identification - appear most promising. Among other recommendations, the authors suggest that the U.S. Navy consolidate its unmanned system master plans and establish relevant priorities in coordination with the Office of the Secretary of Defense. Increased emphasis on the use of surface platforms rather than submarines as host platforms is recommended.

Book excerpt: Submarines offer a capability to deploy and retrieve unmanned undersea vehicles (UUV) in littoral and blue water Areas of Operation while avoiding detection. Integration of the submarine and UUV through a launch and recovery mechanism offers unique challenges with respect to host submarine safety, UUV recovery, UUV replenishment and life-cycle costs. The Capstone team elicited launch and recovery system requirements from stakeholders and conceived four (4) advanced alternatives and a baseline alternative considered to meet the requirements. Through functional, cost, risk, modeling and qualitative analysis, this study assessed the value of each alternative to stakeholders. Of the concept alternatives explored, a high tech option featuring a carbon fiber structure, electromechanical pulse launch and recovery device and proximity vice contact battery charging and UUV stowage features provided the best value to the stakeholders for the investment. These results highlighted characteristics, including maintenance considerations, upgradeability, design for reliability and design for universal applications considered paramount for a successful system. Project lessons learned uncovered significant risk due to instability of UUV requirements as well as certification issues which adversely affect a submarine/UUV integration project. Early communications between key stakeholders must effectively address these short-comings.

Available in PDF, EPUB and Kindle. Book excerpt: Underwater vehicles and underwater moorings are increasing in tactical importance. As such, it is critical to have a robust and secure communication system connecting underwater vehicles on a long seaborne mission and a ground station. As a matter of fact, the deployment of efficient communication links with underwater vehicles is one of the greatest technological challenges presently confronted by the world's naval forces. To circumvent most of the limitations involved in the use of RF or acoustic channels for perfectly secure communications with underwater vehicles, it is worth considering the feasibility of an optical channel to facilitate a two-way satellite communication link secured via perfectly secure ciphers enabled by a quantum key distribution protocol. This book offers a concise review of underwater communications systems. Our approach is pedagogical, making a strong emphasis on the physics behind the attenuating properties of the oceanic environment and the propagation of electromagnetic signals in the ELF, VLF, and optical bands. We assume the reader is familiar with the basic principles of classical electrodynamics and optics. The system design, components, and noise analysis of an underwater optical communications device are discussed in detail. Furthermore, we offer simulations of the performance of the communication system for different types of ocean waters. Our final conclusion is that it appears to be feasible to design and build underwater communications using optical classical and quantum channels secured with quantum key distribution protocols.

Available in PDF, EPUB and Kindle. Book excerpt: During the Cold War the United States developed the Trident class ballistic missile submarine (SSBN) to replace the aging fleet of forty-one Poseidon ballistic missile submarines. Each of the eighteen Trident class submarines built to carry the mantle of strategic nuclear deterrence was extremely large and quiet with tubes for twenty-four ballistic missiles. Following the breakup of the Soviet Union and the end of the Cold War, the United States conducted a review of its nuclear posture, which determined that only fourteen of these submarines were necessary to meet the needs of U.S. national security. Since these submarines are due for nuclear core refueling and overhaul and thus are no longer required to support U.S. nuclear policy, these submarines will be deactivated or refueled and converted to other purposes. These submarines are only halfway through their design life of forty-two years, and once refueled could be used for other missions. Furthermore, their large size makes these ships a prime candidate for conversion to a large variety of missions that require space, stealth, and endurance, This excess capability has convinced the U.S. Navy that it should develop a concept for converting the first four Trident class ballistic missile submarines into guided missile submarines (SSGN). This program would equip these submarines both for cruise missile operations and as special operations force insertion platforms. Each submarine could carry more than 100 Tomahawk cruise missiles and up to sixty-six special operations personnel with dual Dry Deck Shelter or two Advanced SEAL Delivery System mini-submarines for SEAL deployment.

Available in PDF, EPUB and Kindle. Book excerpt: The Navy wants to develop and procure three new types of unmanned vehicles (UVs) in FY2020 and beyond-Large Unmanned Surface Vehicles (LUSVs), Medium Unmanned Surface Vehicles (MUSVs), and Extra-Large Unmanned Undersea Vehicles (XLUUVs). The Navy is requesting $628.8 million in FY2020 research and development funding for these three UV programs and their enabling technologies. The Navy wants to acquire these three types of UVs (which this report refers to collectively as large UVs) as part of an effort to shift the Navy to a new fleet architecture (i.e., a new combination of ships and other platforms) that is more widely distributed than the Navy's current architecture. Compared to the current fleet architecture, this more-distributed architecture is to include proportionately fewer large surface combatants (i.e., cruisers and destroyers), proportionately more small surface combatants (i.e., frigates and Littoral Combat Ships), and the addition of significant numbers of large UVs. The Navy wants to employ accelerated acquisition strategies for procuring these large UVs, so as to get them into service more quickly. The emphasis that the Navy placed on UV programs in its FY2020 budget submission and the Navy's desire to employ accelerated acquisition strategies in acquiring these large UVs together can be viewed as an expression of the urgency that the Navy attaches to fielding large UVs for meeting future military challenges from countries such as China. The LUSV program is a proposed new start project for FY2020. The Navy wants to procure two LUSVs per year in FY2020FY2024. The Navy wants LUSVs to be low-cost, high-endurance, reconfigurable ships based on commercial ship designs, with ample capacity for carrying various modular payloads-particularly anti-surface warfare (ASuW) and strike payloads, meaning principally anti-ship and land-attack missiles. The Navy reportedly envisions LUSVs as being 200 feet to 300 feet in length and having a full load displacement of about 2,000 tons. The MUSV program began in FY2019. The Navy plans to award a contract for the first MUSV in FY2019 and wants to award a contract for the second MUSV in FY2023. The Navy wants MUSVs, like LUSVs, to be low-cost, high-endurance, reconfigurable ships that can accommodate various payloads. Initial payloads for MUSVs are to be intelligence, surveillance and reconnaissance (ISR) payloads and electronic warfare (EW) systems. The Navy defines MUSVs as having a length of between 12 meters (about 39 feet) and 50 meters (about 164 feet). The Navy wants to pursue the MUSV program as a rapid prototyping effort under what is known as Section 804 acquisition authority. The XLUUV program, also known as Orca, was established to address a Joint Emergent Operational Need (JEON). The Navy wants to procure nine XLUUVs in FY2020-FY2024. The Navy announced on February 13, 2019, that it had selected Boeing to fabricate, test, and deliver the first four Orca XLUUVs and associated support elements. On March 27, 2019, the Navy announced that the award to Boeing had been expanded to include the fifth Orca. The Navy's large UV programs pose a number of oversight issues for Congress, including issues relating to the analytical basis for the more-distributed fleet architecture; the Navy's accelerated acquisition strategies and funding method for these programs; technical, schedule, and cost risk in the programs; the proposed annual procurement rates for the programs; the industrial base implications of the programs; the personnel implications of the programs; and whether the Navy has accurately priced the work it is proposing to do in FY2020 on the programs.

Book excerpt: "Potential adversaries throughout the world continue to acquire and develop sophisticated multi-layered, anti-access, area-denial (A2AD) systems. To maintain its maritime superiority, the United States must continue to innovate systems that are capable of operating in and defeating these A2AD environments. In particular, command of the undersea domain remains vital and will increasingly be critical in facing this future battle space. The challenges our nation faces, however, are not limited only to the technological capabilities of the warfighters, but also include a myriad of confounding constraints. In addition to the expected shortfalls of mission-ready assets, the Submarine Forces also must address significant pressures in defense spending. Nevertheless, unmanned undersea vehicles (UUVs) remain one of the top priorities of the Chief of Naval Operations, as UUVs serve as effective force multipliers, while greatly reducing risk, in critical missions in A2AD environments.

This book was released on 2010 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to study the manning and maintainability requirements of a submarine unmanned undersea vehicle (UUV) program. This case study reviews current commercial and military applications of UUVs and applies their principles to the missions of the Navy's submarine force. Past and current UUV efforts are lacking requirements documents and the formal systems engineering process necessary to produce a successful program of record. Therefore, they are not being funded for use by the war-fighter. The Navy must develop formal concepts of operations (CONOPS) for the missions and systems that it wants to produce and allow industry to begin development for a formal future UUV program. Furthermore, the military has developed countless unmanned systems that have been developed for use in the water, on the ground and in the air, from which the Navy can apply important lessons learned. Lastly, analysis suggests that the Navy should continue to support the use of a submarine detachment for operation and maintainability of future vehicle programs.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in command and control of Autonomous Underwater Vehicles (AUVs) using acoustic communications are crucial to future Fleet objectives, particularly in Very Shallow Water Mine Countermeasures (VSW MCM). Understanding of the capability to redirect missions, provide relatively high rate downloads of mission information, and perform cooperative tracking for multi-vehicle systems is cunently limited to some bounding data based on fixed node expenments while the impact of working in the environment presented by a moving vehicle is not understood. The main objectives of this dissertation were to investigate and demonstrate the capabilities of tactical acoustic control of a dynamic, operational underwater vehicle in the Very Shallow Water (VSW) ocean environment. This necessarily required studies on the limitations of Acoustic Control and relatively High Data Rate Transfer when using commercial acoustic modems in underwater vehicles, and an investigation of their acoustic transmission characteristics. Comprehensive empirical evidence through field validation with the ARIES vehicle indicated that reduced ranges were required for successful acoustic communications in a realistic very shallow water environment. Background noise, multipath reflections, and vehicle induced Doppler shifts all limit the communication link. Occasionally, configurations may be found where vehicle body shielding against multipath destructive interference can be used to advantage. A simulation was developed to demonstrate a solution for reducing the range and conducting multi-vehicle behaviors for cooperative tracking and acoustic communications data transfer.
