This marks the 84th successful launch of an Atlas V rocket, 139th launch for ULA, the second launch for the U.S. Space Force and the sixth flight of the X-37B Orbital Test Vehicle (OTV-6). “The success of this mission resulted from collaboration with our customer while working through challenging, and ever changing, health and safety conditions,” said Gary Wentz, ULA vice president of Government and Commercial Programs. “We were honored to partner with the U.S. Space Force to dedicate this mission to first responders, front-line workers, and those affected by COVID-19. It is truly a unique time in our history and I want to thank the entire team for their continued dedication and focus on mission success.” Relive the countdown and launch in our [USSF-7 Launch Blog](https://www.ulalaunch.com/missions/archived-launched/atlas-v-ussf-7)! ## Related News & Topics [Launch](https://blog.ulalaunch.com/blog/tag/launch) ## [SBIRS GEO Flight 5: ULA successfully launches Atlas V](https://blog.ulalaunch.com/blog/sbirs-geo-flight-5-ula-successfully-launches-atlas-v) May 18, 2021 [Launch](https://blog.ulalaunch.com/blog/tag/launch) ## [AEHF-6: ULA launches first U.S. Space Force mission](https://blog.ulalaunch.com/blog/aehf-6-ula-launches-first-u.s.-space-force-mission) March 27, 2020 [Launch](https://blog.ulalaunch.com/blog/tag/launch) ## [Landsat 9: ULA successfully launches Atlas V](https://blog.ulalaunch.com/blog/sbirs-geo-flight-5-ula-successfully-launches-atlas-v-0) September 27, 2021 - [![Apple App Store Badge](https://blog.ulalaunch.com/hubfs/App_Store_Badge.svg)](https://apps.apple.com/us/app/ula-anywhere-ar/id1454852470) - [![Google Play Store Badge](https://blog.ulalaunch.com/hubfs/google-play-badge.svg)](https://play.google.com/store/apps/details?id=com.ula.anywherear&hl=en) - - - - - - Copyright 2026 United Launch Alliance, LLC.
