On Tuesday, December 9, at 2:16 p.m. ET, SpaceX launched a classified national security payload aboard a Falcon 9 rocket for the US National Reconnaissance Office. The mission, designated NROL-77, marked the 10th and final NRO launch of 2025 and SpaceX’s 11th national security space launch this year.

The Launch

The Falcon 9 rocket lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida, carrying a classified payload designed, built, and operated by the National Reconnaissance Office—the agency responsible for operating America’s fleet of spy satellites.

The first stage booster, tail number B1096, made its fourth flight and successfully landed at Landing Zone 2 back at Cape Canaveral Space Force Station approximately 8.5 minutes after liftoff.

At the NRO’s request, SpaceX ended its live webcast shortly after the booster landed. Because of this, the time and orbit of Falcon 9’s deployment of the NROL-77 satellite are not publicly known.

National Security Partnership

The mission demonstrates the critical partnership between the National Reconnaissance Office and the US Space Force’s Space Systems Command through the National Security Space Launch program.

“The partnership between NRO and SSC continues to strengthen our nation’s space superiority through innovative launch solutions and shared expertise,” said Col. Kathryn Cantu, director of NRO’s Office of Space Launch and NROL-77 mission director. “As space becomes increasingly contested, this partnership enables us to rapidly deploy advanced intelligence capabilities while maintaining the agility and resilience needed to address emerging threats.”

NROL-77 is the second NRO mission launched by SpaceX from the NSSL Phase 2 contract awarded in August 2020. The National Security Space Launch program is a government launch acquisition partnership between Space Systems Command and NRO aimed at ensuring continued assured access to space for national security missions.

The program is overseen and operated by SSC’s System Delta 80, headquartered at Los Angeles Air Force Base in California. The NSSL program uses commercial-like contracts and pricing to save taxpayer dollars while ensuring high-quality service.

Rapid Constellation Expansion

The launch comes as the National Reconnaissance Office rapidly expands its on-orbit satellite constellation. According to the NRO’s launch press kit, the agency has launched over 200 satellites within the last two years.

Earlier in 2025, NRO partnered with Space Systems Command to launch NROL-69, NROL-145, and NROL-174 through various launch programs. Col. Ryan M. Hiserote, NSSL program manager, noted that NROL-77 was the last NSSL mission of the calendar year, with teams now looking forward to a busy 2026.

The Mission Emblem

The NROL-77 mission patch features a flying squirrel, symbolizing hard work and endurance—”always active gathering foundational knowledge from the space domain for the nation and its allies.”

The mission motto, “Another One Gone—Today, Tomorrow, and Beyond,” embodies what the NRO describes as the relentless pursuit of excellence. Every mission counts, every decision matters, and every advancement propels the agency further in maintaining America’s space-based intelligence capabilities.

SpaceX’s National Security Role

The NROL-77 launch underscores SpaceX’s growing role as a critical provider of national security launch services. With 11 national security space launches in 2025 alone, the company has become indispensable to America’s military and intelligence space operations.

The Falcon 9 rocket’s reusability—demonstrated by B1096’s fourth successful flight and landing—has helped reduce launch costs while maintaining the reliability required for sensitive national security payloads.

The successful landing at Landing Zone 2 also highlights SpaceX’s capability to recover boosters on land rather than at sea, providing faster turnaround times for future missions.

Contested Space Domain

Col. Cantu’s emphasis on “increasingly contested” space reflects growing concerns about threats to American satellites from potential adversaries. China and Russia have both developed anti-satellite weapons and demonstrated capabilities that could threaten US space assets.

The rapid expansion of the NRO’s satellite constellation—with over 200 satellites launched in just two years—suggests the agency is moving toward a more resilient architecture with larger numbers of smaller satellites rather than relying on a few large, expensive spacecraft that could become single points of failure.

What Happens Next

With NROL-77 marking the final NRO launch of 2025, attention now turns to 2026, when the National Reconnaissance Office and Space Systems Command expect an even busier launch schedule.

The partnership between SpaceX, NRO, and Space Systems Command through the NSSL program continues to demonstrate that commercial launch providers can deliver reliable, cost-effective access to space for America’s most sensitive national security missions.

As space becomes more contested and crowded, the ability to rapidly deploy intelligence satellites will remain critical to maintaining US space superiority and providing decision-makers with the information they need to address emerging threats around the globe.
