SpaceX provided Falcon 9 launch capacity and integration support for Spaceflight's dedicated rideshare missions and Sherpa OTV deployments on multiple Transporter missions (e.g., Transporter-1 in 2021, Transporter-2 in 2021/2022) until severing ties in 2022 after manifested missions.

SpaceX Falcon 9 has been used as a launch vehicle on Spaceflight rideshare missions; Spaceflight arranged Falcon 9 rideshares to deploy customer smallsats as part of its launch services offerings.

Benchmark Space Systems supplies its Halcyon Avant bipropellant propulsion system (using four 22-N thrusters with HTP and isopropyl alcohol) for Spaceflight's Sherpa-LTC2 orbital transfer vehicle (OTV), which was launched on a Falcon 9 in September 2022 to elevate the orbit of the Varuna Technology Demonstration Mission satellite; additional Halcyon systems supported other Spaceflight-related missions on Transporter-2.

Benchmark Space Systems supplies its non‑toxic chemical propulsion systems (thrusters) to Spaceflight’s Sherpa orbital transfer vehicle series; Benchmark announced an exclusive deal to provide propulsion for Spaceflight’s Sherpa OTV program and planned thruster flights on Sherpa variants.

Spaceflight’s Sherpa-NG mission was planned to carry Benchmark’s Starling warm‑gas thruster hardware into orbit; SpaceNews reported Benchmark thrusters would fly on rideshare missions including Sherpa and that Starling was scheduled to fly on a cubesat on Firefly’s Alpha launch.

Benchmark supplied Halcyon Avant green bipropellant propulsion systems for Spaceflight's Sherpa-LTC OTV family, enabling orbital transfers for rideshare customers (agreements and integrations announced 2020-2021).

Rocket Lab provided launch integration and capacity for Spaceflight rideshare payloads on Electron missions.

Rocket Lab's Electron vehicle has been listed among the launch vehicle family Spaceflight has utilized to provide rides to its smallsat customers, supplying launch capacity for rideshare missions.

Firefly Aerospace acquired Spaceflight (all outstanding stock) in June 2023, internalizing Spaceflight’s rideshare, mission-management, licensing, and Sherpa orbital-transfer-vehicle capabilities and thereby enabling Spaceflight operations under Firefly ownership.

Firefly signed Launch and Brokerage Services Agreement (LBSA) with Spaceflight for dedicated rideshare opportunities on Alpha vehicle (2020); later acquired Spaceflight in June 2023.

Firefly Aerospace entered a launch brokerage agreement with Spaceflight to provide launch vehicle capacity and brokerage services to Spaceflight missions, enabling Spaceflight’s launch offerings.

Following its acquisition (with Mitsui), Yamasa provides commercial rideshare and small-satellite launch services through Spaceflight's business and capabilities — Yamasa (as owner) supplies Spaceflight's launch/rideshare services to satellite operators and mission users (transaction announced Feb 2020; acquisition completed June 2020).

Yamasa Co., Ltd. acted as strategic investor and co-owner (50/50 joint venture with Mitsui & Co.) supplying investment, ownership, and strategic direction to Spaceflight Inc. following the June 2020 acquisition (noted as former co-owner in available records).
