      "summary": "The fleet of manned aircraft accomplishing the Department of Defense\u2019s (DOD\u2019s) Command and Control (C2) and Intelligence, Surveillance, and Reconnaissance (ISR) missions for the joint military community (E-8, E-3, RC-135, WC-135, OC-135, and E-6) is primarily based on Boeing 707 aircraft procured from the 1960s to the early 1990s. As the age of these legacy C2ISR aircraft increases, understanding the Air Force and Navy modernization and recapitalization plans is likely important for Congress. This report examines the Air Force\u2019s and Navy\u2019s current sustainment, modernization, and recapitalization efforts for these Boeing 707-based aircraft, and issues Congress may take into account when considering appropriating funds for continued sustainment and modernization of these aircraft versus funding for recapitalization of these missions to new aircraft.\nThis report addresses potential congressional oversight and appropriations concerns for the sustainment, modernization, and recapitalization of the DOD\u2019s Boeing 707-based legacy C2ISR aircraft fleet. It does not address options for recapitalization currently being offered by industry to other countries. Congress has the authority to approve, reject, or modify Air Force and Navy funding requests for C2ISR aircraft sustainment, modernization, and recapitalization, as well as oversight of the nation\u2019s C2ISR requirements and capabilities. Congress\u2019s decisions on appropriations for the C2ISR force could impact the nation\u2019s C2ISR capabilities and have additional consequences for the U.S. aerospace industry.\nThe starting point for Congress\u2019s debate on legacy C2ISR sustainment, modernization, and recapitalization is the existing Boeing 707-based C2ISR fleet consisting of 89 operational aircraft, which includes\n16 E-8C Joint Surveillance Targeting Attack Radar System (JSTARS) aircraft providing airborne battle management, command and control, intelligence, surveillance, and reconnaissance;\n31 E-3 Sentry Airborne Warning and Control (AWACS) aircraft with integrated command and control battle management (C2BM), surveillance, target detection, and tracking;\n17 RC-135V/W RIVET JOINT aircraft supporting theater and national level forces with near real time on-scene intelligence collection, analysis, and dissemination capabilities;\n2 RC-135U COMBAT SENT aircraft that locate and identify foreign military land, naval, and airborne radar signals to determine detailed operating characteristics and capabilities of those systems;\n3 RC-135S COBRA BALL aircraft that collect optical and electronic data on ballistic missile targets;\n2 WC-135 Constant Phoenix atmospheric collection aircraft that collect particulate and gaseous effluents and debris from accessible regions of the atmosphere supporting the Limited Nuclear Test Ban Treaty of 1963;\n2 OC-135B Open Skies aircraft that perform unarmed observation flights over participating parties of the Open Skies Treaty, and\n16 E-6B Mercury communications relay and strategic airborne command post aircraft.\nPotential congressional oversight and appropriations concerns for the sustainment, modernization, and/or recapitalization of the DOD\u2019s Boeing 707-based legacy C2ISR aircraft fleet include\na potential shortfall in C2ISR capabilities if there is a funding gap for sustainment and upgrades that would keep the weapon systems viable until they are recapitalized;\nascertaining DOD, Air Force, and Navy priorities for sustainment, modernization, and recapitalization;\ndetermining if modernization efforts allow for delayed recapitalization efforts;\nconsideration of shifting some of the legacy C2ISR missions to remotely piloted aircraft;\nthe potential implications of reduced legacy C2ISR aircraft sustainment and modernization, and subsequent diminishing numbers of airframes on any future rounds of base realignment and closure efforts; and\nthe ability of the nation\u2019s industrial base to sustain the legacy C2ISR aircraft force.",
