F-35s for Saudi Arabia? Why Israel and China Angles Complicate a US Sale

The US State Department formally notified Congress on Sept. 17 of plans to sell Saudi Arabia 48 F-35 fighter jets, following President Donald Trump's stated approval last year. The prospective sale would expand access to America’s most advanced exportable fighter aircraft for a long-standing US military ally, with potential implications for defense contractors and regional security dynamics.

Analysis

The equity read-through is concentrated in LMT, but near-term earnings sensitivity is likely limited: incremental airframes would be absorbed into a production system governed by multi-year pricing, capacity allocation, and supplier bottlenecks. The more durable value lies in decades of sustainment, software upgrades, spares, training, and engine maintenance; that favors LMT and RTX over a simple one-time airframe-revenue calculation. BAE Systems (BAESY) also has a secondary content opportunity through F-35 structures and electronic-warfare components.

The key market variable is not the headline approval process but whether it converts into a binding government-to-government agreement with an executable delivery schedule. Over the next 1-3 months, congressional opposition, technology-security restrictions, end-use conditions, or regional-security concessions could delay or resize the opportunity. Over 6-18 months, a confirmed order would improve F-35 backlog visibility but could also create delivery-slot competition with existing international customers, making production-rate guidance and supplier capacity more important than announced unit count.

Contrarian view: this is not automatically a material LMT rerating catalyst. Investors may overcapitalize a prospective aircraft count while underweighting fixed-price program economics and the long lead time before revenue recognition. Conversely, a formal contract could be more meaningful for RTX if engine, spare-engine, and long-term depot arrangements are included, since propulsion aftermarket economics generally carry better incremental returns than initial engine sales.

Key Decisions for Investors

• Maintain a watch-list long bias in LMT rather than chase a headline move; initiate only on a signed agreement or raised F-35 delivery/backlog outlook within 1-3 months. Thesis is 6-18 month backlog and sustainment visibility; invalidate if management maintains production guidance while signaling supplier or delivery-slot constraints.
• Use LMT/RTX as a relative-value monitor: favor RTX if disclosed terms include F135 engines, spares, or depot support, and favor LMT if the agreement confirms incremental airframe slots rather than reallocating existing production. Do not establish the pair until contract scope is public.
• Treat BAESY as a lower-beta secondary beneficiary for a multi-year horizon, but require evidence that component content and production cadence rise rather than merely shift among customers. The risk/reward is weaker than LMT or RTX because F-35 exposure is less concentrated.
• Set an event alert for the end of the congressional review period and any letter-of-offer/acceptance disclosure. A delay, added restrictions, or regional-security conditions should be viewed as a reason to avoid defense-prime momentum longs, not as a buying opportunity.
