The C-40 is a medium-range DV airlift aircraft based on the commercial Boeing 737-700. It is used to transport senior military commanders, Cabinet officials, and members of Congress, as well as performing other support missions.
C-40Bs are equipped with an office-in-the-sky arrangement, including clear and secure voice/data communication and broadband data/video. C-40Cs lack the advanced communications suite, are VIP configured with sleep accommodations, and are reconfigurable to carry 42 to 111 passengers. 
Both versions have modern avionics, integrated GPS and flight-management system/electronic flight instrument system, and HUD. Each aircraft has auxiliary fuel tanks and managed passenger communications.
Recent mods add fully reclining crew rest seats to enable long-endurance missions without pre-positioned relief crews. Both variants are receiving updated Large Aircraft Infrared Countermeasures (LAIRCM) through FY27. Senior Leader Communication Modernization across the executive fleets includes Wideband SATCOM, secure air-to-air/ground comms, commercial WiFi, in-flight information, and enhanced airborne executive phones. Two C-40Bs will be upgraded in FY25 to ensure redundant, survivable and secure/top-secret voice, data, and video conferencing for uninterrupted worldwide C2. C-40Bs are also receiving MUOS-compatible crypto to support upgraded secure, jam-resistant BLOS UHF SATCOM.
Congress trimmed USAF’s request for two additional aircraft to augment the heavily tasked C-32 and C-40 fleets. FY25 instead funds a single C-40D that will be similarly configured to the C-40B but with increased passenger capacity.
