Launch Time: between 7:59 and 8:59 p. m. EDT (2359-0059 UTC)

Rocket: ULA Vulcan Centaur V C4S (four GEM‑63XL solid boosters\, dual BE‑4 main engines) \;
Or bit: Geosynchronous Orbit (GEO)
Mission Type: National Security Space Launch (NSSL) / U.S. Space Force Technology Demonstration\n

Mission Overview

This will be ULA&rsquo\;s first National Security Space Launch (NSSL) u sing the new Vulcan Centaur &mdash\;marking a milestone in U.S. heavy-lift launch capability &n bsp\;The primary payload is the Navigation Technology Satellite‑3 (NTS‑3)\, a U.S. Space Fo rce experimental satellite designed to test adaptive digital navigation signals and anti‑spoofing /jamming resilience.

The launch also includes additional classified payloads\, deploying directly into geostationary orbit via Vulcan&rsquo\;s robust trajectory capability \;
