Unmanned Aerial Vehicles: Background and Issues for Congress
No Description Available.
Air Force Aerial Refueling
Aerial refueling aircraft are key to air operations. The U.S. tanker fleet is large and effective, but old. Modernizing or replacing the current fleet of tankers presents the Department of Defense (DOD) with difficult choices in terms of desired capabilities, force structure, and budget. How this fleet will be maintained or replaced, and on what schedule, has proven controversial.
Air Force Aerial Refueling Methods: Flying Boom versus Hose-and-Drogue
Decisions on the composition of the Air Force aerial refueling fleet were made decades ago, when the primary mission was to refuel long-range strategic bombers. Modifications have been made to many of these tanker aircraft (KC-135s and KC-10s) to make them more effective in refueling fighter aircraft. This report, which will be updated, examines the balance between two different refueling methods in today’s refueling fleet — “flying boom” and “hose-and-drogue.”
F/A-22 Raptor
The F-22A Raptor is a next-generation fighter/attack aircraft that features the latest stealth technology to reduce detection by radar. Using more advanced engines and avionics than the current F-15 Eagle, the F-22A is intended to maintain U.S. Air Force capabilities against more sophisticated enemy aircraft and air defenses in the 21st century. This report examines the Air Force’s F-22A Raptor program, including costs and schedule; considers several key issues, and concludes with a synopsis of recent legislative activity on the program.

Conventional Warheads for Long-Range Ballistic Missiles: Background and Issues for Congress
This report provides an overview of the Administration’s rationale for the possible deployment of conventional warheads on long-range ballistic missiles. It then reviews the Air Force and Navy efforts to develop these systems. It summarizes congressional reaction to these proposals, then provides a more detailed account of the issues raised by these concepts and programs.

Conventional Arms Transfers to Developing Nations, 1997-2004
This report is prepared annually to provide unclassified quantitative data on conventional arms transfers to developing nations by the United States and foreign countries for the preceding eight calendar years. Some general data are provided on worldwide conventional arms transfers, but the principal focus is the level of arms transfers by major weapons suppliers to nations in the developing world. The data in the report illustrate how global patterns of conventional arms transfers have changed in the post-Cold War and post-Persian Gulf War years.

Comprehensive Test Ban Treaty: Pros and Cons
The Comprehensive Test Ban Treaty (CTBT) would ban all nuclear explosions. President Clinton signed it in 1996 and transmitted it to the Senate in 1997. The Senate rejected it in 1999. To enter into force, 44 named nations, including the United States, must ratify the treaty. The Bush Administration opposes ratification but has maintained a moratorium on nuclear testing begun in 1992. This report presents pros and cons of key arguments: the treaty’s implications for nuclear nonproliferation, for maintaining and developing nuclear weapons, for the value of nuclear weapons, and for maintaining U.S. nuclear advantage; monitoring issues; and potential consequences of resuming testing.

Airborne Laser (ABL): Issues for Congress
This report examines the airborne laser (ABL) program and budget status. It also examines a variety of related issues, including the questionable maturity of ABL technologies, the number of ABL platforms the United States should acquire, and to what degree the United STates should invest in alternative technologies in the event that the ABL may not prove successful. This report does not provide a detailed technical assessment of the ABL program (see CRS Report RL30185, The Airborne Laser Anti-Missile Program).
"Bunker Busters": Sources of Confusion in the Robust Nuclear Earth Penetrator Debate
Earth penetrator weapons, often called “bunker busters,” burrow into the ground some tens of feet before detonating, greatly increasing their ability to destroy buried targets. The United States has several types of conventional earth penetrators. The Air Force and the National Nuclear Security Administration (NNSA) are studying a more effective penetrator, the Robust Nuclear Earth Penetrator (RNEP). The FY2005 defense authorization act contained the full RNEP request, $27.6 million. This report explains the budget request and provides details on the RNEP plan.
Cruise Missile Defense
Congress has expressed interest in cruise missile defense for years. Cruise missiles (CMs) are essentially unmanned attack aircraft — vehicles composed of an airframe, propulsion system, guidance system, and weapons payload. The Department of Defense is pursuing several initiatives that seek to improve capabilities against an unpredictable cruise missile threat. These initiatives compete for funding and congressional attention.
F-35 Joint Strike Fighter (JSF) Program: Background, Status, and Issues
This report discusses the background, status, and current issues of the Joint Strike Fighter (JSF) program. The F-35 JSF, also called the Lighting II, is a new strike fighter being procured in different versions by the Air Force, Marine Corps, and Navy. The F-35 program is the Department of Defense's (DOD's) largest weapon procurement program in terms of total estimated acquisition cost. This report details the Obama Administration's proposed FY2010 defense budget requests for F-35 program funding and outlines the issues that Congress must consider when deciding whether to approve, reject, or modify the administration's funding requests.
