This report provides background information on the CG(X) program as it existed prior to its proposed cancellation. For further discussion of the proposal to build Flight III DDG-51s in lieu of CG(X)s, see the CRS report on destroyer procurement.

A letter report issued by the Government Accountability Office with an abstract that begins "The Head Start program provides child development services primarily to low-income families and their children. Federal law allows up to 10 percent of families to have incomes above 130 percent of the poverty line--GAO refers to them as over-income families. Families with incomes below 130 percent of the poverty line, or that meet certain other criteria, are referred to as under-income families. Nearly 1 million children a year participate in Head Start, and the American Recovery and Reinvestment Act provided an additional $2.1 billion. GAO received hotline tips alleging fraud by grantees. In response, GAO investigated the allegations, conducted undercover tests to determine if other centers were committing fraud, and documented instances where potentially eligible children were put on Head Start wait lists. On May 18, 2010 GAO testified on the preliminary results of the ongoing investigation. This report reiterates the findings disclosed in GAO's May testimony, and discusses new findings related to specific fraud allegations at two Head Start grantees. Since GAO's May testimony, HHS has taken a number of actions to address identified weaknesses, such as implementing a fraud hotline. HHS also indicated that …

Under current Missile Defense Agency (MDA) and Navy plans, the number of BMD-capable Navy Aegis ships is schedule to grow from 20 at the end of FY2010 to 38 at the end of FY2015. This report discusses the concerns some have over BMD expansion, as well as BMD funding issues.

Correspondence issued by the Government Accountability Office with an abstract that begins "Combating weapons of mass destruction (WMD) and their means of delivery is one of the greatest challenges the United States faces. Traditionally, the use of WMD--which include chemical, biological, radiological, or nuclear weapons--has been constrained by the logic of deterrence and of diplomacy, but these constraints may be of less utility in preventing the use of WMD by rogue states or terrorist groups. The Department of Defense (DOD) assigns top priority to dissuading, deterring, and defeating those who seek to harm the United States directly, especially extremist enemies with WMD. In 1994, Congress established an interagency committee, now known as the Counterproliferation Program Review Committee (CPRC), with a variety of duties related to coordinating the activities and programs of federal agencies that address improvements in the U.S. government's efforts to combat WMD. The Secretary of Defense, as chairman of the CPRC, is required to report its findings biennially. The Departments of Energy, State, and Homeland Security and the Office of the Director of National Intelligence are also members of the CPRC, and must provide it with access to information on all pertinent programs, projects, and activities. The Assistant …

Testimony issued by the Government Accountability Office with an abstract that begins "This testimony discusses issues related to women in management. Although women's representation across the general workforce is growing, there remains a need for information about the challenges women face in advancing their careers. In 2001, using 1995 and 2000 data from the Current Population Survey, we found women were less represented in management than in the overall workforce in 4 of the 10 industries reviewed. We also found differences in the characteristics and pay of male and female managers, which we explored using statistical modeling techniques. To respond to Congress' request that we update this information to 2007, we addressed the following three questions: (1) What is the representation of women in management positions compared to their representation in nonmanagement positions by industry? (2) What are the key characteristics of women and men in management positions by industry? and (3) What is the difference in pay between women and men in full-time management positions by industry?"

The Navy for several years has carried out a variety of irregular warfare (IW) and counterterrorism (CT) activities, and has taken some steps in recent years to strengthen its ability to conduct such activities. Among the most readily visible of the Navy's current IW operations are those being carried out by Navy sailors serving ashore in Iraq and Afghanistan. The Navy's IW and CT activities pose a number of potential oversight issues for Congress, including the definition of Navy IW activities, specific Navy IW budget priorities, and how much emphasis to place on IW and CT activities in future Navy budgets.

This report presents difficult-to-find statistics regarding U.S. military casualties in Operation New Dawn (OND), Operation Iraqi Freedom (OIF), and Operation Enduring Freedom (OEF, Afghanistan), including those concerning post-traumatic stress disorder (PTSD), traumatic brain injury (TBI), amputations, evacuations, and the demographics of casualties. Some of these statistics are publicly available at the Department of Defense's (DOD's) website, while others have been obtained through contact with experts at DOD. Daily updates of total U.S. military casualties in OND, OIF, and OEF can be found at the DOD's website, at http://www.defenselink.mil/news/casualty.pdf.

The Department of Defense (DOD) in recent years has leased some foreign-built cargo ships for total periods, including options and renewals, of almost 10 years -- a length of time that some observers argue effectively circumvents a legal requirement that U.S. military ships be built in U.S. shipyards. These observers, particularly the American Shipbuilding Association (ASA), have proposed reducing the current five-year legal limit on ship leases to two years for foreign-built ships. DOD has opposed the idea, arguing that its ship leases are the most cost-effective way to meet its needs for the ships in question. This report briefly discusses this issue, as well as related legislation.

The Navy has begun a multi-billion dollar program to modernize its 84 existing Aegis cruisers and destroyers over a period of more than 20 years. This report explores this program in detail, including the reasons for the program and the oversight issues it poses for Congress. This report will be updated as events warrant.

The Navy has been procuring Virginia (SSN-774) class nuclear-powered attack submarines (SSNs) at a rate of one per year for the past several years, and a total of 12 boats have been procured through FY2010. The Navy's proposed FY2011 budget increases the procurement rate to two boats per year. This report discusses the Navy's proposed FY2011 budget, which requests $3,441.5 million in procurement funding to complete the procurement cost of the 13th and 14th Virginia-class boats.

The planned size of the Navy, the rate of Navy ship procurement, and the prospective affordability of the Navy's shipbuilding plans have been matters of concern for the congressional defense committees for the past several years. The issue for Congress that is discussed in this report is how to respond to the Navy's proposed force structure and shipbuilding plans. Decisions that Congress makes on this issue could significantly affect future U.S. military capabilities, Navy funding requirements, and the Navy shipbuilding industrial base.

This report discusses issues Congress faces regarding the Navy's proposed FY2011 budget, particularly as relating to destroyer procurement plans and programs.

Concerns about hate crimes have become increasingly prominent among policymakers at all levels of government in recent years. This report compiles state statutes pertaining to hate crimes, including in the context of federal legislation such as the Violent Crime Control and Law Enforcement Act of 1994 and the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act (the latter of which was signed by President Obama on October 28, 1999).

The Travel and Transportation Reform Act of 1998 required federal employees to use travel charge cards to pay for the expenses of official government travel. The dollar volume of travel card transaction has nearly doubled from FY1999 to FY2009. This report discusses card misuse committed by federal employees, and Congress's response, which has included hearings and legislation intended to enhance travel card management and oversight.

This report discusses the procedures for when a Senator is chosen to fill a Senate vacancy during a session of Congress, i.e., when the appointed Senator can begin his or her term of office, and how long the Senator remains in office (until the new "Senator-elect" is sworn in and seated by the Senate).

This report provides an assessment of the use of nitrogen trifluoride for removing oxide and water-caused contaminants in the fluoride salts that will be used as coolants in a molten salt cooled reactor.

The authors describe the implementation of a phase-retrieval algorithm to reconstruct phase and complex amplitude of structures on EUV lithography masks. Many native defects commonly found on EUV reticles are difficult to detect and review accurately because they have a strong phase component. Understanding the complex amplitude of mask features is essential for predictive modeling of defect printability and defect repair. Besides printing in a stepper, the most accurate way to characterize such defects is with actinic inspection, performed at the design, EUV wavelength. Phase defect and phase structures show a distinct through-focus behavior that enables qualitative evaluation of the object phase from two or more high-resolution intensity measurements. For the first time, phase of structures and defects on EUV masks were quantitatively reconstructed based on aerial image measurements, using a modified version of a phase-retrieval algorithm developed to test optical phase shifting reticles.

In 2003, the National Association of Regulatory Utility Commissioners (NARUC) and National Energy Technology Laboratories (NETL) collaboratively established the International Clean Energy Coalition (ICEC). The coalition consisting of energy policy-makers, technologists, and financial institutions was designed to assist developing countries in forming and supporting local approaches to greenhouse gas mitigation within the energy sector. ICEC's work focused on capacity building and clean energy deployment in countries that rely heavily on fossil-based electric generation. Under ICEC, the coalition formed a steering committee consisting of NARUC members and held a series of meetings to develop and manage the workplan and define successful outcomes for the projects. ICEC identified India as a target country for their work and completed a country assessment that helped ICEC build a framework for discussion with Indian energy decisionmakers including two follow-on in-country workshops. As of the conclusion of the project in 2010, ICEC had also conducted outreach activities conducted during United Nations Framework Convention on Climate Change (UNFCCC) Ninth Conference of Parties (COP 9) and COP 10. The broad goal of this project was to develop a coalition of decision-makers, technologists, and financial institutions to assist developing countries in implementing affordable, effective and resource appropriate technology and …

Between October 14, 2009 and February 22, 2010 sediment samples were received from 100-BC Decision Unit for geochemical studies. This is an analytical data report for sediments received from CHPRC at the 100 BC 5 OU. The analyses for this project were performed at the 325 building located in the 300 Area of the Hanford Site. The analyses were performed according to Pacific Northwest National Laboratory (PNNL) approved procedures and/or nationally recognized test procedures. The data sets include the sample identification numbers, analytical results, estimated quantification limits (EQL), and quality control data. The preparatory and analytical quality control requirements, calibration requirements, acceptance criteria, and failure actions are defined in the on-line QA plan 'Conducting Analytical Work in Support of Regulatory Programs' (CAW). This QA plan implements the Hanford Analytical Services Quality Assurance Requirements Documents (HASQARD) for PNNL.

A fuel cell is an electrochemical energy conversion device that produces electricity during the combination of hydrogen and oxygen to produce water. Proton exchange membranes fuel cells are favored for portable applications as well as stationary ones due to their high power density, low operating temperature, and low corrosion of components. In real life operation, the use of pure fuel and oxidant gases results in an impractical system. A more realistic and cost efficient approach is the use of air as an oxidant gas and hydrogen from hydrogen carriers (i.e., ammonia, hydrocarbons, hydrides). However, trace impurities arising from different hydrogen sources and production increases the degradation of the fuel cell. These impurities include carbon monoxide, ammonia, sulfur, hydrocarbons, and halogen compounds. The International Organization for Standardization (ISO) has set maximum limits for trace impurities in the hydrogen stream; however fuel cell data is needed to validate the assumption that at those levels the impurities will cause no degradation. This report summarizes the effect of selected contaminants tested at SRNL at ISO levels. Runs at ISO proposed concentration levels show that model hydrocarbon compound such as tetrahydrofuran can cause serious degradation. However, the degradation is only temporary as when the impurity …
