Should the military depend on a single private company for its satellite launches?

SpaceX is beginning the process of phasing out its Falcon 9 rocket to implement the Starship vehicle. This transition aims to improve efficiency and profitability for the company.

Why it matters

The shift creates uncertainty for national security interests because many current military satellites are not designed to fit inside the Starship vehicle. This gap could lead to potential delays in critical launch operations.

SpaceX maintained a dominant position in 2025, accounting for 85% of total U.S. rocket launches. While Starship is intended to replace the existing fleet, competitors currently lack the capacity to provide comparable services.

The players

SpaceX

An aerospace manufacturer and space transportation company that leads the U.S. market in orbital launch activity.

United States Space Force

The branch of the U.S. Armed Forces responsible for military satellite operations and space-based national security.

The details

SpaceX is moving toward the Starship vehicle to capture gains in efficiency and operational profit. However, because the design dimensions of the new vehicle differ from the Falcon 9, the United States faces a challenge in ensuring existing military hardware remains compatible with upcoming launch systems.

In 2025, SpaceX performed 85% of total U.S. rocket launches.

The Big Picture

The transition to Starship marks a significant inflection point for the National Security Space Launch program, as the current orbital infrastructure was largely designed around the capabilities of the Falcon 9 rocket. This shift forces a reevaluation of satellite design standards that have governed U.S. space operations for years.

Any delays in launching military satellites could impact the reliability of national security communications and intelligence networks. As SpaceX phases out its older technology, the government will likely need to adjust procurement schedules to maintain current capabilities.

The takeaway

The move to Starship highlights the risks of relying on a single provider for the vast majority of national launch needs. Policymakers and military planners will need to prioritize satellite redesign or secondary launch options to avoid future service gaps.
