"Two slips becomes a pattern. A third would price the 10X out of every G700 head-to-head decision through 2028." That is one Dassault-network broker on background, framing the consensus view across the brokerage desks covering the Falcon 10X order book in May 2026. Dassault Aviation launched the Falcon 10X in May 2021 with a 2025 entry-into-service target. The program has now slipped twice. The first delay moved certification to 2026; the second to 2027 to 2028; the third, which AINonline coverage from Q1 2026 and brokerage commentary in Q2 2026 increasingly treat as the base case rather than the downside, would push first delivery into 2029 or later.
Across Dassault Aviation public press surfaces on the Falcon 10X program since the May 2021 launch, AINonline and Aviation International News coverage of the certification timeline through May 2026, the Bombardier Global 7500 and Global 8000 production cadence as the demand-absorption comp, the Gulfstream G700 slot market behavior, and the Falcon 8X in-service fleet utilization data, the structural read is that the 10X delay is not a Dassault-specific story. It is the single largest supply-side variable in the ultra-long-range equation through 2028. Three desks confirmed the read in independent conversations.
The delay produces three downstream effects. First, the Falcon 10X represents roughly 18 to 30 percent of incremental ultra-long-range capacity through the decade if Dassault hits the original cadence; each year of delay holds that capacity off the market. Second, the supply gap created by the delay flows directly into Gulfstream G700 slot premiums and Bombardier Global 7500 parity pricing, both of which Bryant has framed in the peer pieces. Third, the Falcon 10X order book itself is increasingly an option position rather than a delivery position, with order-holders weighing 10X cancellation against G700 slot acquisition.
The third-delay base case
Dassault launched the Falcon 10X in May 2021 as the company's ultra-long-range flagship and most ambitious civil aircraft program since the Falcon 7X. The original program spec: 7,500 nautical mile range at Mach 0.85, the widest cabin in business aviation at 9 feet 1 inch, Rolls-Royce Pearl 10X engines (a clean-sheet development), and an all-new fly-by-wire flight deck. The original entry-into-service target was 2025.
In late 2022, Dassault confirmed a delay to 2026 for first delivery, citing development complexity on the Pearl 10X and integration challenges. The official Dassault press surfaces framed the slip as a refinement rather than a fundamental issue. AINonline coverage at the time read the delay as the first signal that the program was tracking longer than the original budget.
In 2024, Dassault Aviation CEO Eric Trappier confirmed during the company's earnings call that first delivery would slip again, this time to 2027 with 2028 as a working window. Dassault attributed the second slip to additional certification work on the Pearl 10X engine program at Rolls-Royce and continued integration testing. Industry coverage placed the slip more bluntly: the Pearl 10X engine program was running behind, the wing construction (carbon-fiber composite) was running behind, and the avionics integration was running behind. None of the three subsystems had been independently de-risked by 2024.
The 2026 read on the timeline is sharper. AINonline's Q1 2026 coverage of Dassault's annual program update placed the entry-into-service target at "2028, possibly later" without quoting a firm date. NBAA and EBACE press coverage from May 2026 consistently used 2028 or 2029 framing on the 10X. Dassault has not officially confirmed a third slip. The broker consensus has moved ahead of the official communication.
What Dassault has actually said versus broker reality
Dassault's official position through May 2026 maintains a 2027 to 2028 first-delivery window. The Falcon 10X press surface carries program update content but no revised certification target. The most recent Dassault earnings call (Q1 2026, late February) referenced continuing certification work without renewing the 2025 entry-into-service guidance.
Two desks read the official Dassault position as buying time on shareholder communication. The third desk reads it as Dassault genuinely targeting 2027 to 2028 with two material risks remaining (Pearl 10X engine type certification and wing-spar fatigue testing) either of which would push entry-into-service further. All three desks agree on the bottom line: an operator who needs ultra-long-range delivery before 2029 cannot rely on the Falcon 10X.

Three Dassault-network desks, May 2026
The pattern of carrier expectations versus official program timelines is familiar from other clean-sheet civil aviation programs. Boeing's 777X certification has slipped repeatedly against the manufacturer's official guidance. Bombardier's CSeries (now A220) shipped years behind original program targets. Pearl 10X is Rolls-Royce's first clean-sheet civil business jet engine since the Pearl 15 (which is in service on the Global 6500 and Global 7500); the development cadence on a new engine type at this thrust class is rarely faster than five to seven years from first run to certification. The Pearl 10X first run was 2023. Five to seven years places certification between 2028 and 2030 on the engine alone, before integration testing on the airframe.
Why the slip widens G700 slot premiums
The mechanism is supply absorption. The Falcon 10X is a direct competitor to the Gulfstream G700 and the Bombardier Global 7500 and Global 8000. The three airframes share roughly overlapping mission profiles: ultra-long-range (7,000 plus nautical mile), wide cabin, intercontinental flight legs, principal-tier flight departments. An operator deciding among the three is choosing primarily on cabin width (Falcon 10X widest), delivery date (Gulfstream G700 fastest at this point), and engine maintenance program (each manufacturer's own).
A Falcon 10X delivered in 2025 to 2026 would absorb meaningful demand on the new-build side and would generate Falcon 8X trade-up activity on the secondary side. The 8X pre-owned market would soften. The 10X order book would deliver. Gulfstream G700 slot premiums would compress as some buyers chose the Falcon over the early-delivery G700 slot.
A Falcon 10X delivered in 2028 (best case from current broker consensus) leaves three to four years of cumulative ultra-long-range demand sitting elsewhere. The Bryant peer piece on the G700 slot market places May 2026 trades at $3.0 to $5.5 million per slot premium, with the expected base case across the next twelve months at $4.0 to $7.0 million on positions earlier than Q4 2027. The Falcon 10X delay is one of two structural variables that supports the premium widening; the other is Gulfstream's Savannah production capacity constraint.
A Falcon 10X delivered in 2029 or later (the base case among current brokers) extends the same dynamic for another year. The Bryant base case on the Global 7500 secondary market in the peer piece places parity pricing as the supply equilibrium through 2027 to 2028. Each year of Falcon 10X delay extends that equilibrium by approximately the same period. The compounded read is that ultra-long-range supply discipline could hold through 2030 if the 10X slips a third time.
The G700 and Global 7500 demand absorption
The buyers who would have ordered Falcon 10X positions for 2025 to 2027 delivery have, across the past three years, redistributed across two airframes. The data is anecdotal at the broker level rather than published, but the pattern is consistent.
A meaningful share has moved to the Gulfstream G700 order book. Gulfstream certified the G700 in March 2024, ahead of any Falcon 10X equivalent milestone, and began deliveries in Q2 2024. The G700's cabin is narrower than the Falcon 10X but wider than every other Gulfstream product. For an operator prioritizing delivery date over the widest-cabin spec, the G700 became the path. Gulfstream's order book ran into late 2027 to mid-2028 at recent reporting; AINonline coverage from Q1 2026 places the production rate at 50 to 60 airframes per year.
A second share has moved to the Bombardier Global 7500, and increasingly to the Global 8000 which entered service in early 2025. The 7500's wide cabin and 7,700 nautical mile range overlap directly with the Falcon 10X program targets, with a small cabin-width gap that does not move many flight departments off the spec. Bombardier's Toronto Pearson production runs at 30 to 35 airframes per year on the Global 7500, with the 8000 sharing capacity. The pre-owned market on the 7500 trades at parity to new (the Bryant peer piece details the supply mechanics).
A third share is sitting in place on existing Falcon 8X airframes, waiting for the 10X to certify before trading up. The Falcon 8X pre-owned book runs four to seven airframes at any given moment, with low-time examples trading 17 to 28 percent below new-build list. That is shallower than a normal aviation depreciation curve, and the mechanism is the same: 8X operators are not selling because the natural upgrade path (the 10X) is not available.
Each year of 10X delay redistributes more demand into the G700 and 7500 order books and holds more 8X pre-owned inventory off the secondary market. The net effect is upward pressure on G700 slot premiums, supported parity pricing on the Global 7500, and supported 8X residual values.
What buyers on the 10X order book are actually doing
The Falcon 10X order book is increasingly a portfolio of optionality rather than a portfolio of delivery commitments. Broker conversations in Q1 to Q2 2026 surface three patterns.
First, some 10X position-holders are negotiating their position out of Dassault and into Gulfstream G700 slot acquisitions, using the time freed by the delay to move into available inventory. The trade-off is the slot premium ($3.0 to $5.5 million on May 2026 trades per the Bryant peer piece) versus the optionality of holding the 10X position at progress-payment levels. Some position-holders cash out the 10X deposit and pay the G700 slot premium; others hold both positions as a hedge.
Second, some 10X position-holders are extending their current Falcon 8X operations rather than ordering different airframes. The 8X carries the operator's existing crew, maintenance program, and operational familiarity. For an operator running multi-decade Dassault relationships, the value of staying inside the Falcon ecosystem against the value of a near-term Bombardier or Gulfstream airframe is more weighted than for a first-time ultra-long-range buyer.
Third, some 10X positions are being quietly resold to entities treating them as inventoried allocations, the same pattern Bryant detailed in the G700 slot market piece. The 10X order book mechanism allows position transfers with Dassault's consent. Premium-paid 10X positions are not visible in public listings; the trades clear through broker networks and family-office placement agents. The premium ranges are thinner than on G700 slots because the underlying delivery date is uncertain, but the pattern is forming.
Three questions for a 10X position-holder
First, ask whether your 10X position is structured as a deposit-and-progress-payments contract or as a hard delivery commitment with penalty clauses. The difference matters on the resale market. A deposit-and-progress-payments position transfers cleanly with Dassault's consent and minimal penalty exposure. A hard delivery commitment with completion-date triggers may face Dassault's right to retain progress payments if the operator walks before certification.
Second, ask what your position's place in the delivery queue is, and whether Dassault has confirmed your position survives a third slip. Some early positions in the order book may be at risk of being prioritized below newer positions if Dassault restructures the delivery schedule against revised certification dates. The contract language on position seniority is meaningful here.
Third, ask whether your operations team can absorb the cabin-width difference between the 10X target spec and the Gulfstream G700 or Bombardier Global 7500 cabin. The 10X widest-in-class cabin is the program's defining feature for many buyers; for operators where the cabin width drives the order, the G700 and 7500 are not equivalent substitutes regardless of delivery date. For operators where ultra-long-range capability is the primary spec and cabin width is secondary, the G700 and 7500 substitute cleanly.
The comp table: ultra-long-range supply through 2028
1. Dassault Falcon 10X: delayed; broker base case 2029+. 9 ft 1 in cabin (program spec), 7,500 nm range. The supply disruption case.
2. Dassault Falcon 8X: in service since 2016. 7 ft 8 in cabin, 6,450 nm range. Holding pre-owned residual on 10X delay.
3. Gulfstream G700: certified March 2024; deliveries Q2 2024. 8 ft 2 in cabin, 7,500 nm range. Slot premium $3.0 to $5.5M per the Bryant peer piece.
4. Gulfstream G800: certified 2025; deliveries Q3 2025. 8 ft 2 in cabin, 8,000 nm range. Bridges to longer-range mission profile.
5. Bombardier Global 7500: in service since December 2018; 150+ fleet. 8 ft (four-zone) cabin, 7,700 nm range. Parity pricing on low-time pre-owned per the Bryant peer piece.
6. Bombardier Global 8000: in service early 2025. 8 ft cabin, 8,000 nm range. Stablemate to 7500 with extended range.
Read of the table
Two patterns run through the comp set. The first is that cabin width is the only spec where the Falcon 10X program holds a meaningful advantage over its direct competitors, and the gap is roughly 11 to 13 inches at the widest point. That is material for operators where cabin volume is the primary mission-profile driver. For most operators, the range and engine maintenance program are the dominant decision variables, and the Falcon 10X program advantage compresses materially.
The second is that every year of 10X delay is a year of revealed preference among ultra-long-range buyers. Each year that the 10X does not certify, more buyers commit to alternative airframes, more Falcon 8X operators trade up to G700 or Global airframes rather than waiting, and more 10X positions resell to entities holding them as financial options rather than delivery commitments. The cumulative effect is to erode the 10X's commercial competitive position even when (or if) the airframe enters delivery.
The Bryant base case is that a 10X certified in 2028 absorbs roughly 40 to 60 percent of the demand that the original 2025 entry-into-service would have absorbed. A 10X certified in 2029 or later absorbs 25 to 40 percent. The other 60 to 75 percent has already migrated to Gulfstream and Bombardier order books or has settled into the Falcon 8X pre-owned market.
The Bryant Read
The Falcon 10X delay is the largest single variable in ultra-long-range business jet supply through 2028. Each year of slip holds 18 to 30 percent of incremental ultra-long-range capacity off the market and redistributes that demand into Gulfstream G700 slot premiums and Bombardier Global 7500 parity pricing. The broker consensus that a third delay is the base case is the working market read, not the downside scenario.
The buyer's actionable read is that the Falcon 10X cannot be relied on for delivery before 2029, and possibly later. Operators with near-term capability requirements should treat the 10X as optionality rather than delivery commitment. Operators with the widest-cabin requirement face a real opportunity cost in switching to Gulfstream or Bombardier airframes; operators where range and delivery date dominate the decision have clean alternative paths.
