Artemis II: The Companies Behind the Rocket (And the Bill)

Hey there, bargain hunter. On April 1, 2026 — yes, April Fools' Day — NASA did something it hasn't done in 54 years: it sent human beings toward the Moon. Artemis II lifted off from Kennedy Space Center's Launch Complex 39B at 6:35 p.m. EDT, carrying four astronauts on a 10-day lunar flyby. The mission went off with what ground crews called "barely a hitch." For once, the space program delivered on time.

For investors, the more interesting question is not what happened in the sky. It's what happened in the contracts — and what it tells you about the publicly traded names strapped to that rocket.

Scoreboard: What Just Happened

Artemis II is the second flight of the Space Launch System and the first crewed mission of the Orion spacecraft. The crew — NASA's Reid Wiseman, Victor Glover, and Christina Koch, plus Canadian Space Agency astronaut Jeremy Hansen — will fly a free-return trajectory around the Moon and back to Earth. The mission is expected to set multiple human spaceflight records, including the farthest distance any human has ever traveled from Earth: approximately 252,000 miles.

This is not a landing. There is no moonwalk. But it is the critical test flight that unlocks everything that comes after — including the planned lunar landing on Artemis IV, currently targeted for 2028.

The Roster: Public Companies On That Rocket

This was not a one-company show. The SLS and Orion system is a prime example of distributed government contracting — with several publicly traded aerospace names holding the most significant pieces of the pie.

• Lockheed Martin (LMT) — Prime contractor for the Orion crew module. Lockheed led the design, development, testing, and production of the capsule where the four astronauts are currently living.
• Boeing (BA) — Prime contractor for the SLS core stage, including the fuel tanks and flight avionics that control the rocket during ascent. Boeing manufactures the 212-foot core stage at NASA's Michoud Assembly Facility in New Orleans.
• Northrop Grumman (NOC) — Built the twin solid rocket boosters that provided more than 75% of the thrust at liftoff, plus the abort motor and attitude control motor for the Orion launch abort system.
• L3Harris Technologies (LHX) — Parent company of Aerojet Rocketdyne, which provides the RS-25 main engines, eight auxiliary engines, and 12 reaction control thrusters for the Orion crew module.
• Teledyne Technologies (TDY) — Teledyne Brown Engineering built the adapter connecting the Orion capsule to the SLS rocket and contributed to the Exploration Ground Systems.

Beyond those five, the program's full contractor list runs even deeper. The complete roster of prime contractors includes Axiom Space, Bechtel, Blue Origin, Amentum, Jacobs, and Maxar Space Systems — with more than 2,700 suppliers across 47 U.S. states contributing to the broader Artemis supply chain.

The Real Reason This Is Complicated

Here is what the press releases won't tell you: Artemis II is also a monument to cost-plus contracting done at massive scale — and the numbers are genuinely uncomfortable.

Each SLS launch costs approximately $4 billion, according to the White House's own 2026 budget proposal. The program's total cumulative spend has exceeded $60 billion. The original per-launch projection, set early in development, was $500 million. That is an 8x cost overrun on a per-mission basis. The SLS program slipped its first launch date more than 26 times across its development history, with the original 2016 target ultimately becoming the November 2022 Artemis I flight.

Under cost-plus contract structures, the math works differently than it does in the commercial world. Contractors submit invoices for expenses, and NASA reimburses them — plus a fixed fee that represents profit. If Boeing discovers a technical problem requiring redesign, they bill NASA for the engineering hours. The contractor's profit stays the same whether the program runs on budget or not. Taxpayers absorb the overruns, not the contractor.

NASA's own Inspector General found that Boeing received approximately $234 million of a possible $262 million in available award fees between fiscal years 2013 and 2017 — a period when the program was accumulating years of schedule delay and hundreds of millions in cost overruns. Critics called it paying for failure. The structure hasn't changed materially since.

The Business Case, Company by Company

Lockheed Martin (LMT)

Lockheed is the cleanest Artemis story from an investor standpoint. As prime contractor on Orion, it has clear, ongoing revenue visibility tied directly to the mission sequence. The company ended 2025 with a record $194 billion backlog — more than two and a half years of forward revenue visibility — on full-year revenue of $75.05 billion. Management guided 2026 sales to $77.5 billion to $80.0 billion. Free cash flow guidance for 2026 sits at $6.5 billion to $6.8 billion. Lockheed is continuing to develop and assemble Orion spacecraft for Artemis III, IV, and V, giving it multi-year contract runway regardless of the SLS debate. The primary risk: fixed-price contract exposure. Lockheed absorbed $950 million in classified program losses at Aeronautics in 2025, a reminder that large government programs can generate large one-time charges. Wells Fargo initiated coverage with an Equal Weight rating and $650 price target, citing slower growth and weaker free cash flow relative to peers.

Boeing (BA)

Boeing's Artemis story is messier. The company is the prime contractor for the SLS core stage, but the program's future is actively contested. The Trump administration's fiscal year 2026 budget proposal called for terminating SLS and Orion after Artemis III, describing the SLS as "grossly expensive" and noting it has exceeded its budget by 140 percent. Congress pushed back and explicitly mandated funding for Artemis IV and V — a $4.1 billion allocation for future SLS rockets. Boeing employees working on the rocket were warned of potential layoffs in February 2025 as the contract situation remained uncertain. The bottom line: Boeing has near-term SLS revenue locked in through at least Artemis III, but the long-term trajectory of the program is a genuine political variable. Artemis is a small fraction of Boeing's total revenue, but a successful Artemis II does provide a positive data point for a company that has endured a rough stretch.

Northrop Grumman (NOC)

Northrop's Artemis exposure is real and diversified. The company built the solid rocket boosters that provided over 75% of liftoff thrust, manufactures the Orion abort motors, and was also developing the HALO habitation module for the now-cancelled Lunar Gateway. That Gateway cancellation in March 2026 is a notable headwind — Northrop had been pegged as the prime contractor for HALO, one of the few direct lunar infrastructure plays in the publicly traded space. On the broader business: NOC ended 2025 up 32.6% year-to-date, carrying a $95.7 billion backlog. The primary near-term risk is the B-21 Raider stealth bomber program, where Northrop recorded a $477 million loss provision on low-rate initial production — a fixed-price contract problem that does not affect the Space Systems business directly, but does weigh on headline earnings.

L3Harris Technologies (LHX)

L3Harris is the parent of Aerojet Rocketdyne, which provides the RS-25 engines — the same engines that powered more than 100 Space Shuttle missions, now upgraded for the SLS. Aerojet also supplies the reaction control thrusters for Orion and the jettison motor for the launch abort system. The Artemis program is not a headline driver for LHX given the company's much larger defense electronics and communication systems footprint, but it represents a stable, long-duration revenue stream tied to a program with congressional support across party lines.

The Real Threat to Legacy Primes: The SpaceX Question

No analysis of Artemis is complete without acknowledging the commercial alternative sitting next to it on the runway. SpaceX is developing the Starship Human Landing System for Artemis III and IV, contracted to transport astronauts from lunar orbit to the surface. The SLS is not reusable — it must be rebuilt from scratch every single mission. SpaceX's Starship is designed to be fully reusable. NASA Administrator Jared Isaacman has acknowledged the public has "invested over $100 billion and has been very patient" with the program, and has signaled openness to transitioning to commercial heavy-lift systems after Artemis III. That is a structural long-term risk for Boeing's SLS revenue and, to a lesser degree, for Northrop's booster business. The political coalition protecting SLS — built around jobs in Alabama, Texas, Louisiana, and Florida — has successfully resisted similar proposals for over a decade. But it is not invincible.

Bull / Base / Bear

• Bull: Artemis II succeeds cleanly. Political momentum builds. Congress funds Artemis IV and V in full. Lockheed's Orion backlog extends through the decade. Northrop captures incremental lunar surface contracts. LHX benefits from RS-25 production continuity.
• Base: Artemis II succeeds, SLS transitions to commercial lift after Artemis III as Isaacman has signaled. Lockheed retains Orion prime contract under a modified architecture. Boeing's SLS revenues roll off post-Artemis III. New entrants (SpaceX, Blue Origin) absorb the heavy-lift work.
• Bear: Post-Artemis II budget battles resume. Congress fails to sustain multi-year funding. A second-term political reset defunds Artemis IV. Lockheed, Boeing, and Northrop each absorb program write-downs as hardware in progress is shelved.

Cheap Investor Checklist: What to Track Now

• Artemis II mission success or abort — a successful 10-day lunar flyby is the single most important catalyst for program continuity and contractor revenue.
• FY2027 NASA budget resolution — watch whether Congress maintains the $4.1 billion Artemis IV/V SLS funding allocation or revisits it in reconciliation.
• Lockheed Q1 2026 earnings (April 23) — listen for any updated Orion production commentary and fixed-price contract loss disclosures.
• NASA's post-Artemis II commercial transition timeline — any acceleration of the Starship HLS program or Isaacman statements on SLS sunset are direct signals for Boeing's SLS revenue runway.
• Northrop Grumman HALO program cancellation impact — with the Lunar Gateway cancelled in March 2026, quantify what HALO revenue Northrop had expected and whether it is being reallocated.
• L3Harris RS-25 production contract renewal terms — the existing RS-25 supply agreement is the cleanest recurring Artemis revenue line in the group.
• Congressional elections and NASA state delegation composition — the Alabama, Texas, Louisiana, and Florida delegations are the SLS political firewall. Any change in their committee positions matters.

Bottom Line

If Artemis II completes its 10-day mission without major incident, the program earns the political legitimacy it desperately needs — and the near-term revenue picture for LMT, NOC, and LHX stays intact. Boeing's SLS future remains the most contested variable in the group, given the administration's stated preference for commercial alternatives and a cost structure that has ballooned to $4 billion per flight.

Lockheed is the cleaner hold here: Orion is the crew vehicle regardless of what happens to the SLS booster below it, and a $194 billion backlog provides insulation. Northrop is a solid second, with caveats around the Gateway cancellation. Boeing's Artemis exposure is real but narrow relative to the company's total footprint — watch it as a sentiment driver, not a fundamental one.

The rocket worked. The contracts already paid out. Now watch what Washington does next.
