Sommario/riassunto |

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. |

Sommario/riassunto |

"This book delves into the analytical methods used to study the performance of 6G technologies, covering simulation techniques, performance metrics, and predictive modelling. Introducing the core principles of 6G technology, the author discusses the advantages and disadvantages of the technology and explains how wireless communications have evolved, from 1G through to 6G, with current open issues explained. With cyber security being at the heart of all technologies, this book offers a separate chapter on how to monitor 6G-based systems and designing technologies to ensure privacy from potential hackers; this is addressed thoroughly in chapter fourteen's Security by design'. The other topic at the heart of technology, sustainability, is presented with a complete review of energy-efficient hardware and the different types of green communication technologies, |

an important topic for the modern day and more importantly, the future designing technologies. A plethora of case studies are included throughout and popular applications such as AI and IoT are applied to 6G technology."-- |
