Infrastructure for runway-based spaceflight

The 15,000-square-foot complex will feature a 5,000-square-foot mission control and operations center alongside a 10,000-square-foot hangar. The hangar is sized to accommodate the Aurora spaceplane, a reusable, rocket-powered vehicle designed to operate like a traditional aircraft from conventional runways. The facility will also include dedicated avionics and payload workspaces, as well as a flight simulation office.

Grayson Ardies, CEO of OSIDA and Executive Director of ODAA, described the groundbreaking as a turning point for the spaceport.

“For years, we’ve talked about Oklahoma’s potential in commercial spaceflight. Now we’re putting that potential into motion. Dawn Aerospace is bringing a fundamentally different approach to reaching space, one that uses a conventional runway rather than a traditional rocket launchpad. That’s exactly the kind of innovation we want to attract to Infinity One,” Ardies said.

Aurora spaceplane capabilities and microgravity contracts

Dawn Aerospace has completed 64 test flights of the Aurora vehicle to date. In 2024, the spaceplane established a world speed record by reaching an altitude of 20 kilometers (approximately 66,000 feet) from a runway in 118.6 seconds. The final vehicle is designed to reach a top speed of Mach 3.7 and a peak altitude of 100 kilometers.

The new facility will directly support a recently announced commercial campaign. On September 1, 2026, Astral Materials selected Dawn Aerospace for up to 100 microgravity flights from Infinity One Spaceport. Astral Materials plans to use the flights to test next-generation materials and semiconductor manufacturing technologies. The Aurora spaceplane’s four-hour turnaround time will allow the company to conduct multiple tests in a single day.

The vehicle is designed to provide approximately two minutes of microgravity per suborbital flight. Recent company statements have cited the exact duration as between 120 and 127 seconds.

Oklahoma’s aerospace economy and Infinity One history

The Infinity One Oklahoma Spaceport is one of 14 spaceports licensed by the Federal Aviation Administration (FAA) in the United States, and it holds the distinction of being the first inland facility. The site has a long aviation history, originally serving as a Naval Air training facility during World War II and later operating as a Strategic Air Command installation during the Cold War.

The $7.5 million investment aligns with broader state economic goals. According to the ODAA, the aerospace and defense industry currently contributes $52.5 billion to the Oklahoma economy and supports over 250,000 jobs.

Construction of the Dawn Aerospace facility is expected to conclude in the fall of 2027. The company plans to begin flying the full-performance Aurora spaceplane from the site later that year.

AirPro News analysis

The development of inland spaceports like Infinity One represents a necessary evolution in commercial spaceflight infrastructure. Coastal vertical launch facilities are increasingly congested, creating scheduling bottlenecks for research and payload customers. By utilizing a runway-independent spaceplane, Dawn Aerospace can bypass traditional launchpad constraints. If the company successfully achieves its targeted twice-daily flight cadence, this Oklahoma facility could become a blueprint for high-frequency, low-cost microgravity research access.

Transitioning to active flight testing

The upcoming captive-carry flight represents a critical milestone for the STARLAUNCH program. Inert flight hardware is expected to arrive at the Kennedy Space Center hangar in November 2026. Engineering teams will then begin assembly and testing of the rocket-aircraft interface to ensure the Lockheed F-104 Starfighter can safely carry the suborbital vehicle.

Tim Franta, CEO of Starfighters Space, stated that the planned captive-carry flight will move STARLAUNCH 1 from design and ground-based development directly into flight testing.

“Our approach is deliberately incremental: build the hardware, integrate it with the aircraft, fly it, collect data, and use those results to advance toward separation and powered flight. This work on STARLAUNCH 1 is also expected to generate engineering and operational experience to inform the future development of STARLAUNCH 2.”

The December 2026 mission is designed to test aircraft integration, evaluate aerodynamic behavior, and establish operational procedures. Piercarlo Ciacchi, Director of Flight Operations and Chief Pilot of Starfighters Space, noted that the flight will capture essential data for the FAA and the United States Space Force (USSF).

“December’s captive-carry mission would essentially be step one of a multi-flight campaign, building processes for our launch team while capturing data for the FAA and the Space Force as we move toward propulsive air launch.”

Following the December 2026 captive-carry mission, the company plans to conduct a drop test over the Atlantic Ocean. This will be followed by a demonstration of the integrated propulsion system.

Hardware integration and propulsion development

The December 2026 flight may also serve a dual purpose by incorporating hardware from the company’s Wind Tunnel in the Sky program. On October 8, 2026, Starfighters Space announced the completion of its first flight hardware for this initiative, manufactured by Italian engineering firm Robby Moto Engineering S.R.L. (RME). The assembled flight articles measure 3.65 meters in length and 178 millimeters in diameter.

During the STARLAUNCH 1 flight, the company may fly this newly completed Wind Tunnel in the Sky hardware under the opposite wing of the Lockheed F-104 Starfighter on a customer-funded rideshare mission. In this configuration, the hardware will simultaneously serve as an aerodynamic counterweight for the STARLAUNCH 1 vehicle.

Propulsion development is also advancing in parallel. On September 9, 2026, Starfighters Space signed a Memorandum of Understanding with Florida-based Vaya Defense & Space to evaluate the Vortex-Hybrid rocket engine for the STARLAUNCH system. Data collected during the December 2026 flight will support Vaya Defense & Space in developing a hybrid rocket motor aligned with the specific requirements of STARLAUNCH 1.

The STARLAUNCH development pathway

Starfighters Space operates the world’s only commercial fleet of flight-ready Mach 2+ supersonic aircraft. Based at the Kennedy Space Center, the company utilizes its fleet to provide pilot training, in-flight testing, and microgravity research, while actively developing air-launch capabilities for space payloads.

The STARLAUNCH program is the company’s primary air-launch initiative. STARLAUNCH 1 serves as the initial suborbital development vehicle, designed to pave the way for STARLAUNCH 2, a larger vehicle intended for orbital launches.

The program has met several technical milestones throughout the year. On January 21, 2026, the company announced the successful completion of subsonic and supersonic wind tunnel testing for STARLAUNCH 1. These tests demonstrated clean separation behavior at Mach 0.85 and Mach 1.3. Subsequently, on February 20, 2026, the program advanced to a Critical Design Review (CDR) with support from GE Aerospace to confirm design maturity.

Addressing the hypersonic testing bottleneck

The aerospace and defense industries are currently facing a significant bottleneck in hypersonic testing. Traditional ground-based wind tunnels are heavily oversubscribed and typically offer only seconds of test time per run. Airborne platforms like the Lockheed F-104 Starfighter fleet offer sustained testing at speeds exceeding Mach 2 in real atmospheric conditions.

This capability provides a complementary method to compress development timelines for defense primes and commercial space companies, allowing them to gather sustained aerodynamic data outside of traditional laboratory environments.

AirPro News analysis

We view the activation of the STARLAUNCH flight test campaign as a notable indicator of the shifting economics in high-speed aerospace testing. By utilizing legacy supersonic platforms to bypass the constraints of ground-based infrastructure, commercial operators are positioning themselves to capture overflow demand from defense primes and space launch developers. If the December 2026 captive-carry flight successfully validates the aerodynamic integration, it will likely accelerate the timeline for propulsive air-launch systems, offering a viable alternative to traditional vertical launch architectures for smaller payloads.

The dual-use nature of the December 2026 flight, which tests the launch vehicle while simultaneously flying a commercial payload as a counterweight, demonstrates a highly efficient approach to flight test monetization. This strategy allows the operator to offset development costs while proving out multiple distinct business lines on a single sortie.

FCC Authorizes SpaceX 15000 Satellite Direct-to-Device Network

The FCC approved SpaceX to deploy 15,000 D2D satellites in low Earth orbit, targeting a standalone mobile service launch in 2028.

FCC Authorizes SpaceX 15000 Satellite Direct-to-Device Network

The Federal Communications Commission (FCC) has granted Space Exploration Technologies Corp. (SpaceX) authorization to deploy and operate a new constellation of 15,000 non-geostationary orbit (NGSO) satellites designed for direct-to-device (D2D) mobile connectivity.

The regulatory approval, issued via Order DA 26-1078 on October 6, 2026, includes a waiver allowing the aerospace manufacturer to utilize its own spectrum rather than leasing capacity from terrestrial carriers. This decision establishes the regulatory foundation for SpaceX to launch an independent, space-based mobile network capable of competing directly with traditional telecommunications operators.

Istanbul Aviation Forum, the meeting point of the global aviation industry, April 27-28, 2027

Regulatory approval and network architecture

The FCC authorization permits SpaceX to operate the 15,000 satellites across nine low-altitude orbital shells, ranging from 326 kilometers to 335 kilometers above Earth. The Gen2 D2D constellation is distinct from the company’s existing broadband network, operating at much lower altitudes to improve the radio link to standard, unmodified smartphones.

Under the terms of the order, SpaceX faces strict deployment deadlines. The company must launch and operate 50 percent of the authorized constellation by October 7, 2032. Full deployment of all 15,000 satellites is required by October 7, 2035.

“This action allows SpaceX to improve the quality of D2D services, increase capacity, and advance broadband connectivity for consumers in the United States and worldwide.”

The FCC noted in the order that the planned deployments will reshape spectrum-based connectivity by improving competition and expanding consumer choice. SpaceX is targeting peak speeds of 150 Mbps per user for the new mobile network.

Spectrum acquisitions and infrastructure strategy

To support the independent network, SpaceX has aggressively acquired spectrum assets. On October 8, 2026, digital infrastructure investment firm Grain Management announced a definitive agreement to sell its entire nationwide 800 MHz spectrum portfolio to SpaceX. The transaction includes 14 MHz of paired 800 MHz spectrum.

Low-band spectrum is highly valued in telecommunications for its ability to travel long distances and penetrate physical barriers like buildings. This acquisition addresses a critical technical gap for the planned Starlink Mobile service, enabling robust indoor coverage without relying on terrestrial roaming partners.

“Our spectrum expertise allows us to connect the strategic value of these assets with the technologies and operators that can realize their potential. This agreement with SpaceX brings that capability to bear at extraordinary scale, with the potential to change where and how Americans connect.”

The Grain Management agreement follows a prior transaction approved by the FAA on May 12, 2026, in which SpaceX acquired 65 megahertz of spectrum from EchoStar Corporation. The EchoStar deal included 2 GHz mobile satellite service bands, providing the initial mid-band capacity for the D2D network.

Shifting from partner to direct competitor

SpaceX initially entered the direct-to-cell market through a partnership model. The company collaborated with T-Mobile US, Inc. to utilize a fleet of approximately 650 first-generation D2D satellites, aiming to eliminate mobile dead zones using T-Mobile’s PCS spectrum.

The broader D2D satellite market has historically relied on these supplementary partnerships. Competitors such as AST SpaceMobile and Lynk Global have developed space-based cellular networks designed to integrate with existing carriers, such as AST SpaceMobile’s partnership with AT&T Inc.

The October 2026 FCC waiver and subsequent spectrum acquisitions signal a strategic departure for SpaceX. By securing its own low-band and mid-band spectrum, the company is positioning Starlink Mobile as a standalone carrier. Following the regulatory approval and the Grain Management announcement, shares of major US telecom operators including AT&T, Verizon Communications Inc., and T-Mobile experienced significant declines as markets priced in the competitive threat.

SpaceX targets initial launches of the Gen2 D2D satellites in 2027. The company plans to launch its next-generation mobile service in the first half of 2028, pending FCC approval of the Grain Management spectrum transfer.

Technical challenges in very low Earth orbit

Operating a constellation at altitudes between 326 and 335 kilometers presents specific aerospace engineering challenges. Satellites in very low Earth orbit (VLEO) experience significant atmospheric drag, requiring frequent replacement. Industry experts note that maintaining a 15,000-satellite constellation at these altitudes will necessitate a high and sustained launch cadence to replace deorbited units.

Network capacity also remains a technical hurdle. While SpaceX targets peak speeds of 150 Mbps, telecommunications analysts caution that this capacity must be shared across all users within a single satellite’s beam. Consequently, while the space-based network will provide ubiquitous geographic coverage, it may struggle to match the data capacity of dense terrestrial cellular networks in urban environments.

AirPro News analysis

SpaceX is leveraging its near-monopoly in heavy-lift launch to build a telecommunications architecture that would be economically unviable for any other operator. The atmospheric drag in VLEO requires a replacement rate that only a vertically integrated launch provider can sustain. By accepting the high capital expenditure of constant launches, SpaceX gains the physics advantage of proximity, closing the link budget to standard smartphones without requiring massive, complex deployable antennas on the spacecraft.

The acquisition of the 800 MHz portfolio is the linchpin of this strategy. Without low-band spectrum, a satellite-only network is strictly an outdoor, rural solution. With it, Starlink Mobile can theoretically provide the indoor penetration necessary to serve as a primary mobile carrier. If SpaceX successfully executes the 2028 commercial rollout, traditional terrestrial carriers will face a competitor burdened by zero cell tower leases, zero fiber backhaul costs, and total geographic reach.
