Isar Aerospace and SEOPS Sign Five-Launch Rideshare Deal

European launch provider Isar Aerospace and US-based rideshare integrator SEOPS have signed a Multiple Launch Service Agreement for five dedicated missions scheduled between 2028 and 2030. The contract expands SEOPS’ Waymaker rideshare program with European launch capabilities and brings Isar Aerospace’s 2028 manifest near full capacity.

Announced in a press release on September 15, 2026, the agreement builds on a previous single-launch contract secured in 2025, bringing the total number of joint missions between the two companies to six. The launches will utilize Isar Aerospace’s Spectrum launch vehicle, lifting off from the company’s dedicated pads at Andøya Space in Norway and Spaceport Nova Scotia in Canada.

Expanding the Waymaker rideshare program

SEOPS launched its Waymaker dedicated rideshare program in May 2026 to provide commercial and US government customers with access to Low Earth Orbit (LEO). The program aims to address a market analysis environment where demand for dedicated rideshare capacity is outpacing available supply. The agreement follows a rapid expansion phase for SEOPS, which announced in August 2026 that it had repurposed a previously acquired SpaceX Falcon 9 rocket for a 2028 LEO rideshare flight to provide additional opportunities for satellite operators.

SEOPS President Evan Hoyt noted the significance of adding a European provider to their portfolio to ensure resilient access to space.

“Isar has accomplished what very few companies ever do: build a new launch system and successfully reach orbit in what was only its second flight. Partnering for six missions with Isar Aerospace’s launch vehicle Spectrum reflects our confidence in their team and adds a powerful European capability to Waymaker.”

Hoyt added that future access to space requires real choice across vehicles, providers, and geographies, which the company is building through the Waymaker program alongside Isar Aerospace.

Momentum for the Spectrum launch vehicle

The new contracts follows Isar Aerospace’s successful second flight of the Spectrum rocket, designated “Mission Onward and Upward.” During that flight, the vehicle successfully deployed all payloads into orbit, making Isar Aerospace the first European Launcher Challenge startups to achieve orbital insertion.

Isar Aerospace Chief Commercial Officer Stella Guillen stated that the successful second flight directly strengthened market demand for the Spectrum vehicle.

“Signing a second contract with SEOPS is a strong vote of confidence in what we are building. We are proud to partner with SEOPS again and look forward to launching more missions together in the years ahead.”

AirPro News analysis

We view this five-launch agreement as a clear indicator of the tightening capacity in the global commercial launch market, particularly for dedicated LEO rideshare missions. With major US providers heavily booked, integrators like SEOPS are actively diversifying their launch portfolios to ensure reliable access to space for their clients. By securing capacity on Isar Aerospace’s Spectrum vehicle, SEOPS mitigates the risk of domestic launch bottlenecks. For Isar Aerospace, filling its 2028 manifest this early validates its commercial strategy and demonstrates that successful orbital demonstration flights translate rapidly into firm multi-launch contracts.
