Description: The F-35 Joint Strike Fighter (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. The issues for Congress for FY2010 are whether to approve, reject, or modify the administration's funding request for the F-35 program, and whether to approve or reject the administration's proposal to terminate the alternate engine program. Congress' decisions on these matters will affect DOD capabilities and funding requirements and the tactical aircraft manufacturing industrial base.

Description: In late 2007, the Department of Defense (DOD) launched a major procurement initiative to replace most uparmored High Mobility, Multi-Wheeled Vehicles (HMMWVs) in Iraq with Mine-Resistant, Ambush-Protected (MRAP) vehicles by FY2009. MRAPs have been described as providing significantly more protection against Improvised Explosive Devices (IEDs) than uparmored HMMWVs. DOD's decision to acquire a new, smaller MRAP variant for use in Afghanistan; MRAP mechanical, logistical, and readiness concerns could be potential policy issues for congressional consideration. This report will be updated.
