Aerospace
Centered on GE Aerospace. The interactive map combines refreshed market data for covered tickers with static research snapshots and estimates. Dates and source availability vary by company.
The Parts Makers
Castings, forgings and proprietary parts inside every engine and airframe
HWM — Howmet Aerospace
Makes engine components, fasteners, structures and forged wheels; its Engine Products segment produces airfoils, seamless rolled rings and other rotating and structural engine parts.
Why it matters: Its two largest customers are the two big Western engine makers: RTX and GE Aerospace each bought about 11% of Howmet’s third-party sales in 2025 (HWM 10-K 2025).

TDG — TransDigm
Designs and makes highly engineered, mostly proprietary aircraft components with significant aftermarket content; its products are on nearly every commercial and military aircraft in service.
Why it matters: Its commercial shipments run ahead of Boeing and Airbus delivery schedules, so it feels the airframers’ production rates first (TDG 10-K FY2025).

The Engine Makers
Sell the engine once, then service it for decades
GE — GE Aerospace
Designs, builds and services jet engines: the LEAP and CFM56 (through CFM International, its 50-50 venture with Safran), the GEnx, GE9X, GE90 and CF6 for widebodies, and military engines such as the F110, F404, F414, T700 and T901.
Why it matters: An installed base of about 50,000 commercial and 30,000 military engines feeds an aftermarket that is about 70% of revenue: each engine sold earns service revenue for decades (GE 10-K 2025).
Outlook: In the first half of 2026 total engine deliveries rose 37% and LEAP deliveries 41%, internal shop visit revenue grew 30%, and remaining performance obligations reached $210.8B at June 30, 2026, up from $190.6B at the end of 2025 (GE 10-Q Q2 2026).

SAFRY — Safran
French aerospace group: GE Aerospace’s 50-50 partner in CFM International, plus nacelles, electrical systems, aircraft interiors and military engines such as the M88.
Why it matters: LEAP deliveries topped 500 for a fourth straight quarter and reached 1,030 in the first half of 2026, up 41%; civil engine spare-parts sales rose 27.9% in dollars (Safran H1 2026).

RTX — RTX (Pratt & Whitney)
Pratt & Whitney, RTX’s engine segment, builds the Geared Turbofan (GTF) family for the Airbus A320neo family, A220 and Embraer E2, and the F135 that powers every F-35.
Why it matters: GE’s direct rival on the A320neo. The GTF powers more than 2,600 aircraft; an accelerated inspection of the PW1100 GTF fleet has kept an elevated number of A320neo-family jets on the ground, with extra shop visits expected through the end of 2026 (RTX 10-K 2025).

The Airframers
The two-company duopoly that picks the engines
BA — Boeing
Builds the 737 narrowbody and the 767, 777 and 787 widebodies, plus fighters, trainers and tankers. GE engines are the sole-source engine on some Boeing models, and the GE9X will power the coming 777X (BA and GE 10-Ks 2025).
Why it matters: Its 2025 10-K reported a potential durability issue on the 777X engine found in inspections, with first 777-9 delivery still expected in 2027. It closed the Spirit AeroSystems acquisition on December 8, 2025 (BA 10-K 2025).

EADSY — Airbus
European jet maker of the A220, A320neo family, A330, A350 and A380; A320neo buyers choose between CFM’s LEAP-1A and Pratt & Whitney’s GTF.
Why it matters: The largest commercial customer of Pratt & Whitney (29% of segment sales before discounts in 2025, RTX 10-K 2025) and a named customer of GE Aerospace (GE 10-K 2025): both engine makers depend on its narrowbody rate.

The Fleet
Where the money ultimately comes from
Airlines & MRO shops
The operators and repair shops that buy engines, spare parts and long-term service agreements, and keep engines flying for decades after delivery.
Governments
The US and allied defense departments that buy combat, rotorcraft and marine engines, and fund much of the military engine development.
