Germany's First F-35 Stealth Fighter Moves Closer To Service With Key Engine Installation
Authored by Sujita Sinha via Interesting Engineering,
Germany's first F-35A fighter jet is now closer to delivery after its engine was installed during final assembly, according to Lockheed Martin. This milestone shows steady progress on one of Germany's biggest defense modernization efforts since the Cold War.

Lockheed Martin Europe posted the update on social media, describing the engine installation as "another key production milestone on the path to delivering advanced 5th Gen capability for Germany."
The company shared photos of the aircraft on the assembly line as workers installed the Pratt & Whitney F135 engine. Now that the engine is in place, the jet will move on to final testing before its first flight and handover to the German Air Force.
Powerplant Transforms Aircraft Into Operational System
Germany's first F-35 uses the Pratt & Whitney F135, which is the most powerful engine in any Western fighter jet today. It produces about 43,000 pounds of thrust with afterburner and is a key part of the jet's design.
The F135 was made specifically for the F-35 and cannot be swapped for another engine. Besides providing power, it also helps the jet stay stealthy. Engineers shaped the exhaust nozzle and air intake to lower radar visibility from different directions.
Installing the engine is a major step in final assembly because it marks the change from a finished airframe to a working combat jet. After the engine is in, technicians start checking how the propulsion system works with the jet's controls, sensors, and software.

Berlin's Response To A Changing Security Environment
Germany decided to buy the F-35A soon after Russia began its full invasion of Ukraine in February 2022. The F-35A will replace the Luftwaffe's old Tornado jets, which have been used for NATO nuclear-sharing missions for many years.
As part of NATO, Germany keeps aircraft and trained pilots ready to deliver U.S. nuclear weapons if needed. With the Tornado nearing retirement, German officials looked for a replacement that could handle future missions.
The F-35A, which takes off and lands like a regular jet, became the top choice for its stealth, survivability, and certification for nuclear missions. German leaders found that no European jet matched these features for the job.
Multi-Billion-Dollar Investment In Future Air Power
Germany has ordered 35 F-35A jets for about $8.4 billion. The deal covers more than just the planes - it also includes pilot training, simulators, logistics, weapons integration, and the infrastructure needed to run the fleet.
This purchase puts Germany in a growing group of European countries that have joined the F-35 program. The Netherlands, Norway, Denmark, Belgium, Italy, Poland, Finland, and Switzerland have all either received or ordered the jet.
As more European countries use the F-35, NATO is shaping its future air combat plans around this common fifth-generation jet. Using the same aircraft makes training, maintenance, and joint missions easier.
Next Steps Before Delivery
The engine was installed following the usual steps at Lockheed Martin's F-35 production line in Fort Worth, Texas. After installation, the jet undergoes additional system checks, fuel testing, and ground runs to ensure everything works properly.
Next, engineers check how the engine works with the jet's software and flight systems before allowing flight tests. Once these steps are done, the jet can be accepted by the customer.
For the Luftwaffe, acquiring the F-35A will give it new capabilities that Germany's current fighter jets do not have. The Eurofighter Typhoon and Tornado can handle air combat and strikes, but neither was built to be stealthy.
The F-35's stealthy design allows it to fly in heavily defended airspace and makes it harder for enemy radar to detect. As advanced air defenses spread, this feature is expected to be key in Germany's future military plans.

Four leading AI models discuss this article
"A single engine install milestone does not imply near-term combat-readiness or NATO deterrence gains; full fleet delivery and lifecycle costs will determine the real impact."
Engine installation is a necessary hurdle cleared, but it is not a near-term game changer for Germany’s defense posture. The F-35A program remains a multi-year, multi-billion investment with large ongoing costs—pilot training, simulators, maintenance, software and weapons integration—beyond the six-figure concept of a single airframe milestone. The article glosses over schedule risk, basing and infrastructure needs, and potential software approvals that could push delivery well past 2029. In a German budget environment, rising lifecycle costs and political headwinds could limit the cadence of upgrades. While the F-35 adds stealth value, it’s not a panacea if readiness and costs lag.
The milestone is largely symbolic; even with the engine installed, the Luftwaffe won’t be combat-ready for years. If budgets tighten or U.S. maintenance/export constraints bite, the promised NATO deterrence gains may be slow to materialize.
"The transition from procurement to long-term sustainment for the German F-35 fleet creates a predictable, multi-decade revenue stream that stabilizes LMT’s cash flow despite potential software-related cost overruns."
The F-35 engine installation is a routine operational milestone for Lockheed Martin (LMT), but it signals a critical shift in European defense spending. For LMT, this confirms the steady revenue recognition of the $8.4 billion German contract, supporting long-term backlog growth. However, the market often ignores the 'hidden' costs of these programs: sustainment and software integration. As Germany integrates these jets into its Luftwaffe, the focus shifts from procurement to the expensive, multi-decade maintenance cycle. While this is a win for LMT's top-line stability, the real risk is the 'software trap'—the F-35 program is notorious for costly, recurring upgrades to its mission systems that often exceed initial budgetary forecasts.
The F-35 program faces persistent cost overruns and technical debt in its Block 4 software upgrades, which could erode the profit margins LMT expects from these long-term international sustainment contracts.
"This is a delivery checkpoint on already-contracted revenue, not a demand catalyst—the real bull case depends on whether European F-35 adoption sustains beyond initial orders or stalls as geopolitical urgency fades."
Engine installation is genuine progress on LMT's F-35 program, but the article conflates production milestone with financial upside. Germany's $8.4B order is already booked; this delivery is execution risk being managed, not new revenue surprise. The real question: does F-35 adoption across 9+ European NATO members signal a durable multi-decade revenue stream, or does it front-load demand into 2025-2030 with a cliff after? LMT's backlog is massive, but F-35 unit economics and margin sustainability under political pressure matter more than a single jet's engine swap.
Political pressure on defense spending could reverse post-Ukraine; Germany's domestic industrial lobby may push for Eurofighter variants instead; F-35 sustainment costs are notoriously high and could trigger buyer's remorse once fleets mature.
"Steady F-35A assembly milestones de-risk LMT's multi-billion European backlog despite headline delivery dates remaining years away."
The engine installation marks tangible assembly progress on Germany's 35-jet, $8.4B F-35A order, reinforcing LMT's European backlog amid heightened NATO demand post-2022. However, the piece downplays execution risks: F135 integration with German-specific nuclear mission systems and supply-chain bottlenecks at Fort Worth could still slip first flight and 2027-2028 deliveries. Broader context missing is Germany's defense budget pressure and potential political pushback on U.S. platforms versus European alternatives. This is steady but not transformative news for near-term revenue.
Germany could still cancel or downsize the buy if fiscal constraints or a new coalition government prioritize domestic Eurofighter upgrades instead, turning this milestone into sunk-cost optics rather than locked-in cash flow.
"The real risk is Germany’s budget discipline and sustainment willingness, which could shrink or delay the 8.4B backlog and erode F-35 margins far more than software upgrade costs."
Responding to Gemini: I’d push the risk beyond software traps. Gemini argues long-term maintenance sustains LMT’s top line, but the real swing factor is Germany’s budgetary discipline and political will to fund multi-decade sustainment amid a crowded European market. If Germany re-prioritizes Eurofighter or offsets, the 8.4B backlog may underperform. Also, Block 4 upgrades aren’t just costs—they’re schedule drag; margins depend on delivery cadence and sustainment pricing.
"The F-35's role in Germany's nuclear sharing mission creates a structural floor for demand that makes the program immune to typical domestic political or industrial lobbying."
Claude, you’re missing the geopolitical leverage here. This isn't just about LMT’s backlog; it’s about the 'nuclear sharing' mission. Germany’s F-35s are the primary delivery platform for B61-12 gravity bombs. This requirement makes the order far stickier than a standard procurement. Political pushback against U.S. platforms is irrelevant when the alternative—the Eurofighter—lacks the necessary nuclear certification. The risk isn't a 'demand cliff,' it's the operational failure of the integration itself, which would force a strategic rethink.
"Nuclear certification eliminates demand cliff risk but introduces regulatory dependency that could compress LMT's margins on the sustainment side."
Gemini's nuclear-sharing argument is stronger than I initially credited, but it cuts both ways. Yes, B61-12 certification locks in the order politically. But that same requirement makes Germany dependent on U.S. approval for any software update or operational change—a leverage point that could delay deliveries or inflate sustainment costs if Washington tightens export controls. The stickiness is real; the margin risk is higher.
"Nuclear requirements amplify execution and cost risks for LMT instead of locking in the order."
Gemini overlooks how nuclear-sharing requirements heighten rather than reduce execution risks for LMT. B61-12 integration demands U.S. approvals that could clash with German budget reviews, potentially delaying the 2027-2028 deliveries amid supply-chain issues at Fort Worth. This creates a feedback loop where political dependency inflates sustainment costs, undercutting the backlog stability both you and Claude assume holds.
The F-35A engine installation is a significant milestone for Germany's defense program, but it also brings long-term maintenance costs and potential software upgrade issues. The political will to fund these sustainment costs and the potential for delays due to U.S. approvals for nuclear-sharing requirements are key risks to consider.
