Gulfstream G600 Active Fleet Reaches 145 in March 2026 (+17.9% YoY), Continuing Double-Digit Expansion — Post-200th-Delivery Milestone Sees ~2.5–2.8 Monthly Deliveries, but G700/G800 Capacity Shift May Compress Future G600 Production Window

G600 reached its 200th delivery milestone in March 2026 (to a North American customer), averaging ~28–31 annual deliveries since its 2019 launch. AviGo data shows 145 active aircraft in March 2026 (vs. 123 in March 2025, +17.9%); Q1 grew from 121 to 145 (+24), faster than the +16 in Q1 2025. But Gulfstream's full-year 2025 158 deliveries included 53 G700s and 13 G800s — the product mix is tilting toward newer types. G600 as a mature type maintains steady deliveries, but as G700 targets ~80 annual units (supported by Safran HEHF), G600 production-line resources may be progressively squeezed. For fractional ownership and charter operators, G600 high availability and mature MRO ecosystem remain a solid mid-term choice. Confidence ★★★.
