                        WASHINGTON — Boeing will build four additional O3b mPower satellites for SES under a contract announced Aug. 7 to expand the second-generation constellation to 11 satellites. 
Boeing is building the first seven O3b mPower satellites under a 2017 contract. Those satellites were all expected to launch in 2021 on two SpaceX Falcon 9 launches, but Boeing’s new contract announcement only mentioned a late 2021 launch for the first set of satellites. A launch date for the four additional satellites was not disclosed.
O3b mPower is based on Boeing’s new 702X series of software-defined satellites. Each O3b mPower satellite will have the ability to beam 50 megabits to “multiple gigabits per second” to customers, Boeing said. 
Boeing and SES said they will collaborate on interoperability between O3b satellites in medium Earth orbit and U.S. government-owned military satellite communications systems. 
“We have built our network around a multi-orbit, multi-frequency, high-throughput, flexible and open architecture increasingly of value to Government users,” SES CEO Steve Collar said in a news release. “We are looking forward to the first launch of O3b mPOWER and excited to extend our partnership with Boeing.”
SES operates a fleet of 20 first-generation O3b satellites built by Thales Alenia Space, and a constellation of roughly 50 geostationary satellites from various manufacturers. 
O3b mPower is a second-generation system designed to bring terabits of capacity for broadband to aircraft, ships, mobile network operators, governments and other end users.
