ULA and SpaceX have already been competing for contracts under the previous Phase 2 edition of NSSL: In total, over five years of Phase 2 launch orders, the military assigned ULA with 26 missions worth $3.1 billion, while SpaceX got 22 missions worth $2.5 billion.

Blue Origin, as well as Northrop Grumman, missed out on Phase 2 when the Pentagon selected ULA and SpaceX for the program in August 2020.

But with Phase 3, the U.S. military is raising the stakes — and widening the field — on a high-profile competition for Space Force mission contracts. Phase 3 is expected to see 90 rocket launch orders in total, with a split approach of categories Lane 1 and Lane 2 to allow even more companies to bid.

Space Force outlined a “mutual fund” strategy to buying launches from companies under Phase 3: The military branch split the program into two lanes, in order to have one that features three companies fulfilling the most demanding and expensive missions, and the other that
