What AST SpaceMobile is building
AST SpaceMobile (NASDAQ: ASTS) is a Midland, Texas satellite company whose pitch is not a dish on a roof. It wants standard, unmodified smartphones — the same 4G and 5G handsets people already carry — to talk directly to a satellite using ordinary cellular spectrum. The satellite is meant to behave like a tower in the sky: voice, data, and video, routed through a mobile operator’s existing network rather than through a separate satellite app.
That is a different product from home Starlink internet, which needs a user terminal. It is also a different bet from most “direct-to-cell” messaging overlays. AST is trying to close a hard link budget with very large phased-array antennas on a relatively small number of spacecraft. Company materials still describe commercial-scale service as scaling through 2026 and beyond. This article is a map of what has actually flown, which operators have signed on, and where Starlink sits on the same board. It is not a ranking of the stock and not a trade instruction.
What has gone into space so far
The hardware in orbit is a sequence of prototypes, then Block 1 commercial birds, then much larger Block 2 birds. Not every launch stayed useful.
- BlueWalker 1 (April 1, 2019, ISRO PSLV): a small technology demonstrator built with NanoAvionics. It decayed from orbit in November 2023.
- BlueWalker 3 (September 10, 2022, SpaceX Falcon 9): the breakthrough prototype. Its ~693 square-foot (64 m²) array unfolded in November 2022. In 2023 AST used it for two-way voice on unmodified phones (including a Samsung Galaxy S22 and an iPhone over AT&T spectrum), then 4G/5G connectivity with reported peak downloads around 14–21 Mbps, plus space-based 5G voice and a video call.
- BlueBird 1–5 (September 12, 2024, Falcon 9): the first commercial Block 1 batch. Five satellites, each with roughly 700 square-foot arrays. AST said all five had unfolded by late October 2024. These birds later supported native VoLTE and SMS tests on AT&T and Verizon core networks, plus video-call demos with Vodafone in a no-coverage area of Wales and with Rakuten in Japan.
- BlueBird 6 (December 23, 2025, ISRO LVM3 from Satish Dhawan): first Block 2 satellite. About 2,400 square feet of phased array, launch mass around 6,100 kg — ISRO’s heaviest LVM3 payload to low Earth orbit at the time. This is the generation AST describes as the operational broadband design.
- BlueBird 7 (April 19, 2026, Blue Origin New Glenn): second Block 2 bird. The upper stage left it in a low, unusable elliptical orbit. AST deorbited it the next day. It does not count as an operating spacecraft.
- BlueBird 8–10 (June 17, 2026, Falcon 9) and BlueBird 11–13 (August 5, 2026, Falcon 9): two triple launches of Block 2 satellites from Cape Canaveral.
How to read the current fleet
After the August 5, 2026 launch, AST said the network had grown to 13 spacecraft in orbit with about 20,000 square feet of combined aperture hardware. That count is BlueWalker 3 plus BlueBirds 1–6 and 8–13. BlueWalker 1 is gone. BlueBird 7 is gone. Block 2 birds still need array unfold and checkout after launch, so “in orbit” is not the same as “in commercial service.”
AST has said BlueBirds 14–16 were close to shipment in August 2026, with production running through BlueBird 46, and has talked about on the order of 45 satellites in 2026 and about 90 for global coverage. Those are company targets, not a completed constellation. Beta service with selected operator partners was still described as a 2026 initiative, including a U.S. plan to activate thousands of digital cells from a handful of gateways — not a finished nationwide consumer product.
Global deals and who is actually named
AST’s commercial model is partner-first: it sells capacity to mobile network operators, who then offer it under their own brands. In an August 10, 2026 update the company said it had signed more than 60 operator partners covering over 3 billion subscribers, with about $1.3 billion of contracted backlog across commercial partners and U.S. government awards. Named, definitive agreements matter more than the headline partner count.
- United States: definitive commercial agreements with AT&T (through 2030) and Verizon (announced 2025, service aimed at 2026). Both have pointed to low-band 850 MHz spectrum as the U.S. coverage layer. AST has also tested Band 14 for FirstNet public-safety use.
- Europe and Africa: a Vodafone commercial framework through 2034, plus SatCo, a jointly owned European satellite service company meant to sell AST capacity to other European operators from a European network operations center. Integration and testing has been described with Vodafone, Orange, Telefónica, Vodafone Ukraine, and Deutsche Telekom, subject to regulation.
- Middle East: a 10-year agreement with stc group (October 2025) that included a $175 million prepayment for Saudi Arabia and selected regional markets.
- Other named operators over the years include Rakuten Mobile (Japan), Bell Canada, TIM, Saudi Telecom, Zain KSA, e& (Etisalat), and Indosat Ooredoo Hutchison. Japan’s MIC has been reported as preliminarily selecting a Rakuten–AST joint venture for a J-LEO program.
- Government: AST has reported multiple U.S. government awards totaling more than $125 million, plus emergency-spectrum work in the U.S., Japan, and with Vodafone Ireland.
How this compares with Starlink
People often flatten “satellite internet” into one product. Starlink and AST overlap on one slice — talking to ordinary phones from low Earth orbit — and diverge on almost everything else.
Starlink’s original business is broadband to a dish or roaming kit: thousands of relatively small satellites, a consumer terminal, and a SpaceX-branded service. Direct to Cell is a second payload. SpaceX has been adding cellular antennas to newer Starlink satellites and selling that layer to mobile operators. In the United States the anchor partner is T-Mobile. The early consumer offer was messaging in places without terrestrial coverage, with voice and data added as more Direct-to-Cell satellites and software came online. The antenna on each Starlink bird is far smaller than a BlueBird Block 2 array (on the order of tens of square feet versus about 2,400). SpaceX’s answer is density: hundreds of Direct-to-Cell-capable satellites already, sitting inside a constellation of many thousands.
AST is doing the inverse. Fewer satellites, much larger arrays, purpose-built as cellular base stations, designed to sit inside an operator’s core network rather than as a separate satellite brand. In the U.S. that has mapped onto AT&T and Verizon, not T-Mobile. AST’s public demos have emphasized voice, video, and tens of megabits to unmodified phones from a handful of large birds. Starlink’s public Direct-to-Cell product has emphasized coverage that is already on, starting with texts, using a fleet that is already huge.
- Device: both aim at unmodified phones for the cellular overlay. Starlink home internet still needs a dish. AST has no consumer dish product.
- U.S. carriers: AST has named AT&T and Verizon. Starlink Direct to Cell has named T-Mobile. A phone’s space fallback, if it arrives, will likely follow the subscriber’s operator, not a single sky network.
- Service shape: Starlink Direct to Cell has been a live, limited overlay (messages first). AST has been a test-and-beta path toward cellular broadband. Neither is a substitute for a dense terrestrial 5G grid in a city.
- Scale: Starlink has the satellite count and launch cadence because SpaceX flies its own rockets. AST has the aperture per satellite and a wholesale seat with many operators at once. Those are different engineering trades, not a finished scoreboard.
What this does not tell you
A launch log and a partner list are evidence of a buildout, not proof that consumer broadband from space is already in your pocket. Arrays still have to deploy. Gateways still have to light. Regulators still have to clear spectrum. BlueBird 7 is a reminder that a successful liftoff is not the same as a working node.
On MarketNeon, ASTS is a ticker like any other: price, volume, crowd mentions, and headlines can be loud while the constellation is still incomplete. This article is context for those prints. It does not rank the name, and it does not tell anyone to buy or sell.
