Loft Federal provides mission-as-a-service for small satellite missions to the U.S. national security space community. It handles the entire process of getting a payload to orbit, offering regularly scheduled missions so clients can focus on their data rather than the launch. The company uses pre-procured satellite buses and proprietary plug-and-play software and hardware to quickly integrate and launch payloads, delivering missions in months instead of years. This makes Loft Federal different from competitors by targeting government payloads with a turnkey, cost-effective, and predictable path to space, backed by a streamlined operations model rather than standalone launch services. The overall goal is to give government and defense organizations reliable, timely access to space for their data-gathering payloads.
