What is the Capacity of Viasat 4?
Viasat's 2023 annual report described a ViaSat-4 design goal of multiple terabits per second of throughput per satellite. That was a forward-looking development target, not an operational capacity measurement or a home internet speed guarantee.
What the ViaSat-4 capacity statement means
The company's fiscal 2023 filing said it was working on the next generation, ViaSat-4, and expected each satellite to provide multiple terabits per second. The statement describes an anticipated design capability. It does not establish a final delivered specification, launch date or commercial service date.
Customers should distinguish a published development goal from a satellite that has launched, completed commissioning and entered service. This page does not present ViaSat-4 as a currently operating residential network.
Satellite throughput is not your download speed
Aggregate throughput describes traffic carried across many connections. It cannot be read as a speed offered to an individual home. A plan's download speed, available capacity at an address, network management and Wi-Fi performance are separate considerations.
For orders through RSINC, our download commitment is at least 80 Mbps. Uploads can reach 3–5 Mbps, but that range is not a guaranteed minimum. RSINC usually sees downloads around 180 Mbps on Unleashed; that is our experience, and actual results vary.
Do not confuse ViaSat-4 with ViaSat-3
Viasat describes the ViaSat-3 design as more than one terabit per second per satellite. Design capacity should still be distinguished from achieved operational capacity; the first ViaSat-3 satellite's deployment issue affected its usable capacity.
ViaSat-3 F2 launched in November 2025 and entered service over the Americas in September 2026. Those milestones concern ViaSat-3, not ViaSat-4. See F2's service announcement explained and ViaSat-3 coverage.

Base an order on the plan available at your installation address, its price, equipment charges and data policy. A future satellite development target is not a reason to assume an automatic upgrade or a specific future speed. Our Viasat pricing guide explains the current residential options.
