C-37 Gulfstream

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 senior leaders’ access to secure data and voice networks, and FAA-required CNS/ATM updates. The fleet has an average 28,000 flying hours of remaining service life.

USAF issued a request for proposal in FY18 for procurement of as many as 40 additional C-37Bs to backfill the now-retired C-20 fleet. FY21 launches wideband SATCOM upgrades as part the Senior Leader Communication Modernization effort across USAF’s executive fleets.

A total of 15 aircraft will be modified to ensure redundant, survivable and secure/top-secret voice, data, and video conferencing for uninterrupted worldwide C2.

USAF took delivery of its fourth C-37B in 2019, a fifth on March 25, 2020, and awarded Gulfstream a $127.4 million contract for two additional aircraft for delivery by September 2021.
