Boeing's SLS Moon Rocket Faces Trump-Era Ax: Which 5 Space Giants Win NASA's Lunar and Nuclear Contracts?
On April 11, 2026, Bloomberg reported that Boeing's Space Launch System (SLS)—the core rocket for NASA's Artemis lunar missions—faces an uncertain future under the Trump administration's NASA leadership. With cost overruns exceeding $20 billion and repeated delays, the SLS program is under scrutiny, potentially opening doors for alternatives in moon base construction, nuclear-powered spacecraft, and agile lunar infrastructure. This pivotal moment in NASA's $4 billion+ annual lunar push raises a key question for investors: who captures the multibillion-dollar contracts as Boeing stumbles?
NASA's Artemis program, aiming for a permanent lunar presence by 2030, has ballooned into a $100 billion+ endeavor encompassing moon bases, human landers, and nuclear propulsion for deep-space travel. Over the past 12 months, Congress infused an extra $10 billion via the One Big Beautiful Bill Act, but SLS woes—highlighted in Boeing's own SEC filings as a high-risk cost-type contract—could redirect funds. Smaller, innovative players in landers and nuclear tech stand to gain, while established primes like Lockheed and Northrop solidify their roles.
Lockheed Martin (LMT): Orion Anchor in Artemis Core
Lockheed Martin, prime contractor for the Orion crew capsule, is deeply embedded in Artemis with minimal SLS exposure. Orion's success in Artemis II (crewed lunar orbit) positions LMT for ongoing crewed missions and Gateway station work. SEC filings confirm Orion as a cornerstone, with steady NASA funding insulated from SLS cuts.
| Metric | TTM Value |
|---|---|
| Market Cap | $141B |
| Revenue Growth | 5.7% |
| EBIT Margin | 10.3% |
| P/E | 28.5 |
| EV/EBITDA | 18.2 |
| Price Return 3M | +36% |
LMT's stable defense backlog and 10%+ margins make it a low-risk winner. Bull verdict: Top pick for reliable lunar exposure.
Northrop Grumman (NOC): Gateway and Upper Stage Stronghold
Northrop Grumman builds the SLS upper stage and leads the Lunar Gateway station, critical for moon base ops. Even if SLS core falters, NOC's Gateway contracts—valued at billions—persist, with nuclear surface power ties emerging. Their diversified space portfolio weathers program shifts.

| Revenue Growth | 2.2% |
| EBIT Margin | 10.2% |
| P/E | 23.1 |
| EV/EBITDA | 15.4 |
| Price Return 3M | +30% |
Attractive 23x P/E and 10% margins signal undervaluation amid lunar upside. Bull verdict: Defensive growth play in infrastructure.
Rocket Lab (RKLB): Agile Launcher Alternative
Rocket Lab's Neutron rocket emerges as a commercial SLS alternative for lunar cargo, with NASA contracts for lunar missions already inked. As Boeing's delays mount, RKLB's rapid iteration and $38B market cap reflect investor bets on reusability trumping legacy systems.
| Metric | TTM Value |
|---|---|
| Market Cap | $39B |
| Revenue Growth | 38% |
| EBIT Margin | -38% |
| P/S | 60x |
| EV/EBITDA | -221x |
| Price Return 3M | +32% |
Hyper-growth (38% revenue) justifies premium multiples despite losses; first Neutron launches in 2026 could catalyze. Bull verdict: High-conviction growth bet.
BWX Technologies (BWXT): Nuclear Propulsion Leader
BWXT specializes in nuclear reactors for NASA's fission surface power and propulsion, key for sustained moon bases. With no direct SLS ties, they benefit from program pivots to nuclear tech, as Artemis demands reliable power for lunar outposts.
| Metric | TTM Value |
|---|---|
| Market Cap | $21B |
| Revenue Growth | 18% |
| EBIT Margin | 11.3% |
| P/E | 64x |

| Price Return 3M | +22% |
Profitable 11% margins and 18% growth command a premium in a niche market. Bull verdict: Essential for long-term lunar viability.
Intuitive Machines (LUNR): Lunar Lander Disruptor
Intuitive Machines' Nova landers won NASA CLPS contracts for Artemis surface delivery, bypassing SLS for commercial paths. Boeing's woes accelerate reliance on such innovators for moon base payloads.
| Metric | TTM Value |
|---|---|
| Market Cap | $3.8B |
| Revenue Growth | -7.9% |
| EBIT Margin | -41% |
| P/S | 12x |
| Price Return 3M | +73% |
Recent missions drove 73% share gains; scaling deliveries unlocks profitability. Bull verdict: Speculative pure-play with breakout potential.
Boeing (BA): The Clear Loser in SLS Limbo
Boeing's SLS core stage, plagued by $20B+ overruns, is the epicenter of Trump-era cuts per Bloomberg and Boeing's 10-K warnings on cost-type risks. SEC filings flag ongoing losses and termination liabilities.
| Metric | TTM Value |
|---|---|
| Market Cap | $171B |
| Revenue Growth | 34% |
| EBIT Margin | -6% |
| P/E | 92x |
| EV/EBITDA | 26.6x |
| Price Return 3M | +3.5% |
Commercial woes overshadow space; SLS cancellation could trigger billions in charges. Bear verdict: Avoid amid execution risks.
Investment Verdict: Ranked Conviction
- LMT (Highest Conviction Buy): Proven executor, fair valuation. 2. NOC: Steady cash cow. 3. RKLB: Growth rocket. 4. BWXT: Nuclear moat. 5. LUNR: High-beta upside. Sell/Avoid BA.
Risks include Congressional SLS bailouts, Artemis delays beyond 2028, or budget sequestration. Monitor Q2 FY2026 NASA awards and Trump NASA nominee hearings for contract shifts.
