Falcon 9 v1.1

Falcon 9 v1.1

The Falcon 9 v1.1 is an American medium-to-heavy orbital launch vehicle developed and operated by SpaceX (Space Exploration Technologies Corp.), based in Hawthorne, California. It serves as the backbone of commercial satellite deployment, crewed spaceflight, and government payload delivery, and represents one of the most significant launch vehicles in the history of spaceflight.

Overview

Standing 71 meters tall with a diameter of 3.65 meters, the Falcon 9 v1.1 is a two-stage rocket powered by SpaceX's Merlin engines, burning liquid oxygen and RP-1 (refined kerosene). It is capable of delivering 22,800 kg to low Earth orbit (LEO) and 8,305 kg to geostationary transfer orbit (GTO), placing it firmly in the medium-to-heavy lift category. One of the vehicle's defining characteristics is its reusability: the first stage is designed to return to Earth and land propulsively, either on a ground pad or an autonomous drone ship at sea, dramatically reducing the cost of access to space.

Development and Variants

The v1.1 designation covers an extended and iterative lineage of the Falcon 9 family, culminating in the Block 5 variant — the most refined and flight-proven configuration. Block 5 introduced improvements to the first-stage thermal protection, landing legs, and engine systems specifically to maximize refurbishment efficiency and reuse cadence. The vast majority of missions in the vehicle's operational history have been flown on Block 5 hardware.

Flight History

Our tracking data covers 754 flights of the Falcon 9 v1.1 across its operational period from 2010 to 2031, recording 641 successes alongside 4 failures or partial failures — a reliability record that ranks among the best of any orbital launch vehicle. This flight volume reflects an extraordinarily high launch tempo, driven largely by SpaceX's own constellation deployment campaigns.

SpaceX itself stands as the vehicle's top customer, primarily through its Starlink broadband satellite program, which has contributed a substantial share of total flight count. Beyond its own payloads, the vehicle has served a broad range of customers including commercial satellite operators and major government agencies.

Notable Recent Missions

Recent missions tracked in our database illustrate the vehicle's diverse manifest. Crew-14 carried astronauts to the International Space Station under NASA's Commercial Crew Program. JSAT-31 delivered a commercial communications satellite to geostationary transfer orbit. Intelligence community payloads flew under the NROL-96 and NROL-157 designations for the National Reconnaissance Office, while USSF-234 served the United States Space Force. KPS-1 represented international commercial satellite deployment.

Significance

The Falcon 9 v1.1's combination of high payload capacity, demonstrated reusability, and sustained reliability has fundamentally reshaped the commercial launch industry. Its cadence and cost profile forced a broad reassessment of launch economics worldwide, and its role in supporting both crewed missions and national security payloads cemented it as a multipurpose workhorse of the modern spaceflight era. Few launch vehicles in history have matched its combination of flight volume and mission diversity.
