Book Description
As the U.S. Navy seeks new and innovative ways to maximize its return from a finite budget, an evaluation of its operational practices must be done, Electrical power consumption and fuel efficiency are major factors in the Total Operating Cost (TOC) of naval ships and systems. An evaluation of an alternative mean for delivering electrical power to motors and pumps was conducted with the understanding that principles of the findings could be applied to fans as well. Adjustable Speed Drives (ASD), AC induction motors, AC synchronous motors, centrifugal pumps, and positive displacement pumps were examined. The technical challenges associated with ASDs were explored. MATLAB was used to calculate the potential power savings to be gained by introducing ASD technology to the Firemain and Chilled Water Systems. MATLAB was also used to calculate fuel cost savings from reduced consumption of Shipboard power.

Book Description
" After nearly a decade and almost $10 billion in development on Zumwalt class destroyers, the Navy changed its acquisition approach from procuring Zumwalts to restarting production of Arleigh Burke class destroyers (DDG 51) and building a new version, known as Flight III. As requested, GAO reviewed the Navy's plans for DDG 51 and missile defense capabilities by (1) evaluating how the Navy determined the most appropriate platform to meet surface combatant requirements; (2) identifying and analyzing differences in design, cost, and schedule of the restart ships compared with previous ships; and (3) assessing the feasibility of Navy plans for maturing and integrating new technologies and capabilities. GAO analyzed Navy and contractor documentation and interviewed Navy, contractor, and other officials. "

Book Description
The Navy has been procuring Arleigh Burke (DDG-51) class Aegis destroyers since FY1985. The two DDG-51s requested for procurement in FY2017 are to be the 75th and 76th ships in the class. The 10 DDG-51s programmed for procurement in FY2013-FY2017 (in annual quantities of 3-1-2-2-2) are being procured under a multiyear-procurement (MYP) contract. One of the DDG-51s funded in FY2016 is to be the first of a new DDG-51 design variation called the Flight III design, which is to incorporate a new and more capable radar called the Air and Missile Defense Radar (AMDR). As part of its action on the Navy's FY2016 budget, Congress provided $1 billion in unrequested procurement funding to help pay for a DDG-51 that would be in addition to those being procured under the 10-ship MYP contract for FY2013-FY2017. The Navy, in its budget submission, notes this additional $1 billion in funding for the DDG-51 program, but does not show the additional DDG-51 in its shipbuilding plan. The $433 million in procurement funding that would be needed to complete the cost of this additional DDG-51 is, however, included as the second item on the Navy's FY2017 unfunded requirements list (i.e., the list of FY2017 programs that the Navy desires, but for which it did not have sufficient funding in FY2017). The Navy estimates the combined procurement cost of the two DDG-51s requested for procurement in FY2017 at $3,393.9 million. The ships have received a total of $182.6 million in prior-year advance procurement (AP) funding. The Navy's proposed FY2017 budget requests the remaining $3,211.3 million needed to complete the ships' estimated combined procurement cost. The Navy's proposed FY2017 budget also requests $16.0 million in so-called cost-to-complete procurement funding to cover cost growth on DDG-51s procured in FY2011. The Navy's proposed FY2017 budget also requests $271.8 million in procurement funding to complete construction of Zumwalt (DDG-1000) class destroyers procured in prior years, and $144.4 million in research and development funding for development work on the AMDR. Potential FY2017 issues for Congress concerning destroyer procurement include the following: whether to approve, reject, or modify the Navy's FY2017 procurement funding requests for the DDG-51 and DDG-1000 programs, and the Navy's FY2017 research and development funding request for the AMDR program; whether to provide some or all of the $433 million in procurement funding needed to complete the funding for the additional DDG-51 that was partially funded with $1 billion in FY2016; whether to provide the Navy with authority for entering into an MYP contract for DDG-51s to be procured in FY2018-FY2022; continued cost growth in the DDG-1000 program; cost, schedule, and technical risk in the Flight III DDG-51 program; issues raised in a January 2016 report from DOD's Director of Operational Test and Evaluation (DOT&E)-DOT&E's annual report for FY2015; and the lack of an announced Navy roadmap for accomplishing three things in the cruiser-destroyer force: restoring ship growth margins; introducing large numbers of ships with integrated electric drive systems or other technologies that could provide ample electrical power for supporting future electrically powered weapons; and introducing technologies for substantially reducing ship operating and support (O&S) costs.

Book Description
This cost-benefit analysis conducted on behalf of MSC compared HSVs against C-17 aircraft, Using financial and operational data garnered from the WestPac Express, as well as third-party research, the researchers investigated the following questions: Is the HSV a better choice for intra-theater lift than AMC7 Should DoD buy or lease? Should the crew be military or civilian? What other theaters require an intra-theater lift platform? How many HSVs does DoD need? The results indicate that in ranges of up to 1,500 nautical miles, HSVs have a speed advantage over C-17 airlift, One HSV can move a single battalion of Marines, whereas AMC7 requires seventeen C-17 aircraft, a number rarely available for such a mission Additionally, during routine FYO3 operations, WestPac Express incurred costs of $ 12 million This saved $8.7 million compared to an estimated AMC7 cost of $20.7 million The study also recommends bareboat leasing to take advantage of the increased operational flexibility, In the absence of significant cost differences, civilian manning is superior to military manning due to organizational fit. The study concludes with a recommendation that MSC institutionalize HSV service in the III MEF AOR and expand the service to all other maritime theaters,

Book Description
The Navy is developing three new ship-based weapons that could improve the ability of Navy surface ships to defend themselves against missiles, unmanned aerial vehicles (UAVs), and surface craft: the Surface Navy Laser Weapon System (SNLWS), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), previously known as the hypervelocity projectile (HVP). The Navy refers to the initial (i.e., Increment 1) version of SNLWS as HELIOS, an acronym meaning high-energy laser with integrated optical dazzler and surveillance. EMRG could additionally provide the Navy with a new naval surface fire support (NSFS) weapon for attacking land targets in support of Marines or other friendly ground forces ashore. The Department of Defense is exploring the potential for using GLGP across multiple U.S. military services. Any one of these three new weapons, if successfully developed and deployed, might be regarded as a "game changer" for defending Navy surface ships against enemy missiles and UAVs. If two or three of them are successfully developed and deployed, the result might be considered not just a game changer, but a revolution. Rarely has the Navy had so many potential new types of surface-ship air-defense weapons simultaneously available for development and potential deployment. Although the Navy in recent years has made considerable progress in developing technologies for these new weapons, a number of significant development challenges remain. Overcoming these challenges will require additional development work, and ultimate success in overcoming them is not guaranteed. The issue for Congress is whether to approve, reject, or modify the Navy's funding requests and proposed acquisition strategies for these three potential new weapons. Potential oversight questions for Congress include the following: Using currently available air-defense weapons, how well could Navy surface ships defend themselves in a combat scenario against an adversary such as China that has or could have large numbers of missiles and UAVs? How would this situation change if Navy surface ships in coming years were equipped with SNLWS, EMRG, GLGP, or some combination of these systems? How significant are the remaining development challenges for SNLWS, EMRG, and GLGP? Are current schedules for developing SNLWS, EMRG, and GLGP appropriate in relation to remaining development challenges and projected improvements in enemy missiles and UAVs? When does the Navy anticipate issuing roadmaps detailing its plans for procuring and installing production versions of SNLWS, EMRG, and GLGP on specific Navy ships by specific dates? Will the kinds of surface ships that the Navy plans to procure in coming years have sufficient space, weight, electrical power, and cooling capability to take full advantage of SNLWS and EMRG? What changes, if any, would need to be made in Navy plans for procuring large surface combatants (i.e., destroyers and cruisers) or other Navy ships to take full advantage of SNLWS and EMRGs? Given the Navy's interest in HPV, how committed is the Navy to completing the development of EMRG and eventually deploying EMRGs on Navy ships? Are the funding line items for SNLWS, EMRG, and GLDP sufficiently visible for supporting congressional oversight?

Book Description
The FFG(X) program is a Navy program to build a class of 20 guided-missile frigates (FFGs). Congress funded the procurement of the first FFG(X) in FY2020 at a cost of $1,281.2 million (i.e., about $1.3 billion). The Navy's proposed FY2021 budget requests $1,053.1 million (i.e., about $1.1 billion) for the procurement of the second FFG(X). The Navy estimates that subsequent ships in the class will cost roughly $940 million each in then-year dollars. On April 30, 2020, the Navy announced that it had awarded the FFG(X) contract to the team led by Fincantieri/Marinette Marine (F/MM) of Marinette, WI. F/MM was awarded a fixed-price incentive (firm target) contract for Detail Design and Construction (DD&C) for up to 10 ships in the program-the lead ship plus nine option ships.Under the DD&C contact awarded to F/MM, Navy has the option of recompeting the FFG(X) program after the lead ship (if none of the nine option ships are exercised), after the 10th ship (if all nine of the option ships are exercised), or somewhere in between (if some but not all of the nine option ships are exercised).

Book Description
Updated 12/10/2020: In December 2016, the Navy released a force-structure goal that callsfor achieving and maintaining a fleet of 355 ships of certain types and numbers. The 355-shipgoal was made U.S. policy by Section 1025 of the FY2018 National Defense AuthorizationAct (H.R. 2810/P.L. 115- 91 of December 12, 2017). The Navy and the Department of Defense(DOD) have been working since 2019 to develop a successor for the 355-ship force-level goal.The new goal is expected to introduce a new, more distributed fleet architecture featuring asmaller proportion of larger ships, a larger proportion of smaller ships, and a new third tier oflarge unmanned vehicles (UVs). On December 9, 2020, the Trump Administration released a document that can beviewed as its vision for future Navy force structure and/or a draft version of the FY202230-year Navy shipbuilding plan. The document presents a Navy force-level goal that callsfor achieving by 2045 a Navy with a more distributed fleet architecture, 382 to 446 mannedships, and 143 to 242 large UVs. The Administration that takes office on January 20, 2021,is required by law to release the FY2022 30-year Navy shipbuilding plan in connection withDOD's proposed FY2022 budget, which will be submitted to Congress in 2021. In preparingthe FY2022 30-year shipbuilding plan, the Administration that takes office on January 20,2021, may choose to adopt, revise, or set aside the document that was released on December9, 2020. The Navy states that its original FY2021 budget submission requests the procurement ofeight new ships, but this figure includes LPD-31, an LPD-17 Flight II amphibious ship thatCongress procured (i.e., authorized and appropriated procurement funding for) in FY2020.Excluding this ship, the Navy's original FY2021 budget submission requests the procurementof seven new ships rather than eight. In late November 2020, the Trump Administrationreportedly decided to request the procurement of a second Virginia-class attack submarinein FY2021. CRS as of December 10, 2020, had not received any documentation from theAdministration detailing the exact changes to the Virginia-class program funding linesthat would result from this reported change. Pending the delivery of that information fromthe administration, this CRS report continues to use the Navy's original FY2021 budgetsubmission in its tables and narrative discussions.
