The Russian aerospace sector is unraveling under the weight of its own ambitions. What began as a desperate pivot to self-sufficiency after 2022 sanctions has devolved into a systemic crisis, with cascading economic, technological, and security risks. For investors, this collapse isn’t just a regional story—it’s a global domino effect threatening aerospace suppliers, sanction frameworks, and the rise of alternatives like China’s COMAC. Let’s break it down.

Russia’s Aerospace Ecosystem: A House of Cards

Russia’s attempt to localize its aerospace supply chain has been a disaster. Despite a 22% budget cut for the Aircraft and Helicopter Production federal project in 2025, the country has delivered only five aircraft since 2022—far below its 2030 target of 1,000. The Comprehensive Program for Aviation Industry Development (KPGA) has been slashed by 50%, with Rostec’s claims of “unaffected production” ringing hollow. The reality? A 45–70% spike in domestic aircraft costs, driven by inflated component prices and workarounds for missing Western parts.

The root cause? Decades of underinvestment in engineering and R&D, compounded by the defense sector’s siphoning of critical resources. Anatoly Gaydansky of Aerocomposite put it bluntly: Russia’s electronic component base is “years behind global standards.” This isn’t just a production slowdown—it’s a collapse of technical capability.

Western Aerospace Firms: Caught in the Crossfire

The fallout for Western suppliers is immediate. Russia’s state-owned VSMPO-AVISMA, the world’s largest titanium producer, has been cut off from Western markets. Boeing and Airbus, which relied on VSMPO for 30% and 50% of their titanium needs respectively, are now racing to secure alternatives. But the transition is costly and time-consuming. Japanese and U.S. suppliers like Osaka Titanium and Allegheny Technologies are stepping in, but Europe’s lack of domestic capacity leaves Airbus and Safran at a disadvantage.

The titanium shortage is just the tip of the iceberg. Western firms are also grappling with delays in electronic components and landing gear systems, as Russian manufacturers struggle to replace Western inputs. For investors, this means watching for production bottlenecks at Boeing (BA), Airbus (EADSY), and Rolls-Royce (RYCEF). The 12-month qualification period for new suppliers is a red flag—any further delays could trigger a domino effect across the global supply chain.

Sanctions and COMAC: A Fragile Alternative

China’s COMAC has emerged as a potential alternative, but it’s far from a silver bullet. The C919, COMAC’s flagship narrow-body jet, has 20 deliveries but still relies on Western engines and avionics. U.S. export restrictions on LEAP-1C engines and Honeywell components have forced COMAC to delay its CJ-1000A engine program until 2030. Meanwhile, the C929 widebody project—originally a joint venture with Russia—is now fully Chinese, but its 2027 completion date is optimistic at best.

COMAC’s partnerships with HAECO and Liebherr-Aerospace for MRO services are a bright spot, but they also highlight the company’s reliance on Western expertise. For investors, the key question is whether COMAC can scale its domestic capabilities fast enough to meet demand. The 2025 Roland Berger report suggests global aerospace resilience is improving, but COMAC’s path is fraught with geopolitical risks.

Investment Implications: Navigating the New Normal

For investors, the collapse of Russia’s aerospace ecosystem presents both risks and opportunities. Here’s how to position your portfolio:

Titanium Suppliers: U.S. and Japanese firms like Allegheny Technologies (ATI) and Osaka Titanium are prime beneficiaries of the supply chain shift. Watch for price spikes and increased R&D spending. MRO Providers: Companies like HAECO and Liebherr-Aerospace, which are partnering with COMAC, could see demand surges as China’s fleet expands. Diversification: Avoid overexposure to COMAC. While it’s a rising star, its reliance on Western tech and geopolitical tensions make it a high-risk bet.

The bigger picture? The global aerospace industry is fragmenting. Western firms must invest in domestic titanium production and R&D to avoid future shocks. Meanwhile, COMAC’s rise could accelerate if sanctions persist, but investors should hedge against the risk of a parallel supply chain that lacks efficiency.

In the end, this crisis is a wake-up call. The days of relying on a single supplier—whether it’s Russia for titanium or COMAC for aircraft—are over. For investors, the lesson is clear: diversify, adapt, and stay ahead of the geopolitical curve.
