The C-37 family provides worldwide special air mission and DV support, consisting of military versions of the ultra-long-range Gulfstream business aircraft.
The C-37A is based on the Gulfstream V and is equipped with separate VIP and passenger areas, secure global voice and data communications suites, enhanced weather radar, autopilot, and advanced HUD. The C-37B, first delivered in 2004, is based on the G550 and adds directional IR countermeasures for self-defense and the advanced Honeywell Plane-View flight deck.
Ongoing mods include commercial wideband SATCOM, to ensure leaders access to secure data and voice networks, and FAA-required CNS/ATM updates. FY25 continues comm suite upgrades as part of the Senior Leader Communication Modernization effort across USAF’s executive fleets.
A total of 16 aircraft will be modified, including two in FY25 , to ensure redundant, survivable and secure/top-secret voice, data, and videoconferencing for uninterrupted worldwide C2. Existing aircraft will receive modernized en route air traffic SATCOMS, which will be standard on future airframes.
USAF aims to acquire as many as 40 aircraft to backfill the retired C-20. Four aircraft were delivered between 2019 and 2022. FY25 funds MUOS-compatible crypto to support secure, jam-resistant BLOS UHF SATCOM upgrades by FY26.
