Boeing Wins 777 Cargo Certification, Loses NASA Moon Rocket Contract, Faces Mixed Outlook

Boeing finds itself navigating two sharply contrasting developments that together define the complexity of its ongoing recovery. On the commercial side, the FAA has certified Mammoth Freighters' converted Boeing 777-200LR cargo jet. This extends the commercial life of widebody airframes and keeps Boeing platforms central to the global freight market.

On the government side, NASA formally cancelled Boeing's contract to build the Exploration Upper Stage for the Space Launch System in February 2026. This is a contract that had ballooned from an original estimate of $962 million to a projected $2.8 billion, as reported by Gizmodo. As noted by Simply Wall St on April 12, 2026, these two developments sit in very different parts of the business but together reshape Boeing's near-term story in ways that go well beyond any single earnings headline.

The Upside of Cargo: 777-200LR Certified by FAA

The certification of the 777-200LR passenger-to-freighter conversion by the FAA of Mammoth Freighters is a significant commercial positive to the widebody ecosystem of Boeing. According to Simply Wall St, the approval indicates that regulators are at ease with approving third-party modifications to Boeing airframes. This is a move that will lengthen the operational and revenue life of the current 777 fleets in an era where e-commerce-led air freight demand is structurally high.

The conversion of the 777-200LR continues to keep Boeing widebodies well within the cargo fleet planning cycles, giving the airframe a competitive edge against Airbus options to operators considering long-range freight capability. The wider freighter policy of Boeing also covers the 777-8F, the specially designed cargo version of the 777X family. Boeing has restarted its production after correcting a structural crack found during testing, according to Air Data News.

The Space Loss: NASA Cuts the SLS Contract

The gains are counteracted by the backlash from the NASA announcement, made by NASA Administrator Jared Isaacman. It was observed that the Exploration Upper Stage programme will be cancelled and that the current Block 1 SLS will be standardised. According to SpaceNews, Boeing's EUS had been part of its $3.2 billion SLS Stages Production and Evolution Contract, awarded in 2022. The EUS development cost had escalated from $982 million in 2017 to a projected $2.8 billion by 2028, and delivery had slipped from 2021 to 2027, a six-year delay. NASA has since contracted ULA's Centaur V as the replacement upper stage, confirmed by Spaceflight Now in March 2026.

Industry Specialist Perspective

NASA Administrator Jared Isaacman was direct in explaining the rationale for cancelling Boeing's EUS, as reported by the Union Leader:

He added that NASA would not "sit idly by when schedules slip, or budgets are exceeded," signalling a clear pivot toward commercial launch providers at the expense of legacy contractors, including Boeing.

Where Boeing Stands: Recovery is not a Linear Process

The financial status of Boeing is still strained. According to Aviation A2Z, the 777X programme alone has charged up with an end-2025 of 15 billion, including a write-down of 4.9 billion in Q3 2025. Boeing CEO Kelly Ortberg has set 777X certification in the second half of 2026, and first deliveries to Lufthansa are now plausibly planned to be in 2027.

Boeing is ramping from 42 to 47 aircraft per month at Renton, with the North Line in Everett set to launch this summer. The cargo certification is a real plus - but with cumulative programme charges of over 15 billion dollars on the 777X alone, and a major government space deal now lost, the only way that Boeing can get back on a steady track of profitability is by doing all three fronts at once.
