Summary

Heart Aerospace is developing the ES-30, a 30-seat clean-sheet hybrid-electric regional aircraft for short-haul routes from smaller airports. Founded in Sweden and now headquartered in El Segundo, California, the company is following an iterative development path built around the Heart X1 and X2 prototypes while bringing more of its batteries, actuation systems, software, and hybrid-electric hardware in-house. On August 12, 2026 the all-electric X1 demonstrator completed its piloted maiden flight at Plattsburgh International Airport in New York, a 27-minute flight that made X1 the largest battery-electric aircraft ever flown and advances technology feeding into the ES-30 program. Heart says it has raised $185M to date, secured 250 aircraft orders plus 120 options and purchase rights, and is targeting ES-30 type certification in 2031 after pushing the target out from 2029.

ES-30

ES-30

In Development

A 30-seat clean-sheet hybrid-electric regional aircraft built around Heart's Reserve Hybrid architecture for short-haul routes. Heart is positioning the ES-30 around lower operating cost, lower noise, shorter-runway access, and zero-CO2 operations on short segments.

Heart unveiled the full-scale X1 demonstrator in 2024 and has shifted to an iterative X1/X2 development path with more in-house technology integration. X1 completed low-speed taxi testing at Plattsburgh in late May 2026, FAA special airworthiness certification on July 23, 2026, and its piloted maiden flight on August 12, 2026 - the largest battery-electric aircraft ever flown. The X2 prototype is intended to mature the hybrid-electric architecture. In parallel, Heart is building the first pre-production, type-conforming ES-30 at its pilot manufacturing plant in Los Angeles, with flight testing on that airframe targeted to begin in 2028 ahead of a revised 2031 certification and entry-into-service target.

What's Next

HX-2 hybrid-electric flight demonstration

With the all-electric X1 having completed its piloted maiden flight on August 12, 2026, Heart's next major flight-test milestone is the X2 pre-production prototype, meant to demonstrate the company's Independent Hybrid propulsion system - the first time Heart's combination of large electric inboard motors and outboard turboprops operates together in flight - and validate the integrated hybrid-electric stack, in-house subsystems, and production methods needed for the ES-30. It remains scheduled for a hybrid-electric flight in 2026; as of September 4, 2026 Heart has not announced an X2 flight or any change to that target.

2026

Build and fly the first pre-production ES-30

Heart is building the first pre-production, type-conforming ES-30 at its pilot manufacturing plant in Los Angeles, distinct from the X1/X2 technology demonstrators. Flight testing on this airframe is targeted to begin in 2028, feeding directly into the FAA Part 25 certification campaign.

2028

ES-30 type certification

Heart pushed its ES-30 type-certification target to 2031, a delay from the prior 2028 goal, the company said around July 29, 2026 - a milestone that would put the program among the first certified hybrid-electric commercial aircraft efforts. The all-electric X1 demonstrator completed its piloted maiden flight on August 12, 2026, and Heart's own August 13, 2026 announcement reaffirmed the 2031 entry-into-service target; the schedule still hinges on maturing the X2 prototype's integrated hybrid-electric powertrain and building the first pre-production, type-conforming ES-30 airframe.

2031

Prepare ES-30 for commercial service

Heart says its goal is to bring the ES-30 into commercial regional service, backed by roughly $9.4B in aggregate customer commitments from launch customers including United Airlines, Air Canada and JSX, while building the surrounding infrastructure and services stack. The company's own public messaging around the August 2026 X1 first flight puts entry into service at 2031, aligned with the type-certification target.

Timeline

2026X1 completes low-speed taxi testing at Plattsburgh

In late May 2026 Heart's all-electric X1 demonstrator completes low-speed taxi testing at its flight-test base at Plattsburgh International Airport in upstate New York - a key step in the ground-test campaign ahead of FAA special airworthiness certification and the aircraft's maiden flight, which the company still targets for 2026.

2026FAA clears X1 for piloted flight testing

On July 23, 2026 the FAA issued Heart a Special Airworthiness Certificate in the experimental category for the all-electric X1 demonstrator at Plattsburgh International Airport, authorizing piloted flight testing. With a 106-foot wingspan and a takeoff weight above 25,000 pounds, the X1 became the largest electric aircraft ever cleared by the FAA for piloted flight, clearing the final regulatory hurdle before its maiden flight.

2026X1 completes maiden flight, largest electric aircraft ever flown

On August 12, 2026 the all-electric X1 demonstrator completed its piloted maiden flight at Plattsburgh International Airport, a 27-minute flight reaching 1,100 feet AGL with the propulsion system delivering over 1 megawatt of power. At a 106-foot wingspan and more than 25,000 pounds takeoff weight, X1 became the largest battery-electric aircraft ever flown, advancing the technology feeding into the ES-30 program.

Airbus

Civilian Aircrafts

Airbus is Europe's largest aerospace company, spanning commercial aircraft, helicopters, defence and space. In civil aviation it remains Boeing's only true peer at global scale and is pairing near-term production growth with longer-term work on lower-carbon aircraft technologies, future single-aisle designs and hydrogen propulsion. The company combines a mature global airliner business with broader aerospace capabilities across defence, space and rotorcraft. Q1 2026 was unusually weak - 114 deliveries (vs. 136 a year earlier), revenue down 7% to EUR 12.65B and adjusted EBIT halved to EUR 300M due to Pratt & Whitney engine shortages and Chinese delivery disruptions - but Airbus reaffirmed full-year 2026 guidance of ~870 deliveries, EUR 7.5B adjusted EBIT and EUR 4.5B free cash flow, with a record commercial backlog above 9,000 aircraft. Output recovered strongly through mid-year: official figures reported July 10 showed 351 deliveries in H1 2026 (up ~15% YoY), Airbus's best first half since 2019, and the backlog stood at 9,216 aircraft at end-June. At a measured Farnborough Airshow (July 20-24, 2026) Airbus booked roughly 157 firm commercial orders plus commitments (of a show-wide $84.7B / 353 firm aircraft), headlined by SMBC Aviation Capital's 100 A320neo-family jets, VietJet's 20 A330neos (~$7.4B), and new A350-1000 orders from Riyadh Air and Philippine Airlines, with CEO Guillaume Faury reaffirming the ~870-delivery full-year target. On July 26 Airbus announced a EUR 5B share buyback and raised medium-term targets, and on July 29 it reported H1 2026 results: revenue up 12% YoY to EUR 33.2B on 351 deliveries, powered by a record Q2 (237 deliveries, +39% YoY). Airbus's official July tally, published August 7, showed the delivery pace cooling further to 67 aircraft (39 customers) and 204 gross orders, taking YTD deliveries to 418 versus 373 at the same point in 2025 - still 51 aircraft ahead of Boeing (367 YTD) but below the roughly 85-90/month cadence needed to reach the 870-aircraft target. August's official tally showed a further cooldown to 47 aircraft delivered to 31 customers and 46 gross orders (including airBaltic firming 10 more A220-300s), taking YTD deliveries to 465 - now requiring an average of roughly 100 aircraft a month over the final four months of the year to hit the 870-aircraft guidance. Part of the August softness traces to a production quality issue on the A330neo: Airbus found a stray tool and other quality lapses on the horizontal tail plane (assembled at its Getafe plant) that nearly halted A330neo deliveries for three months - zero handed over in June and July, just one in August, to Starlux Airlines - before Airbus said in early September the root cause was identified, the issue was isolated and unrelated to the Spain labor dispute, and deliveries had resumed. Two other supply and schedule risks continue to shadow the ramp: Airbus's dispute with Pratt & Whitney over shorted A320neo engine deliveries has hardened into a formal damages claim that could go to arbitration, and the A350F freighter has now penciled in a tentative first-flight date around September 24, 2026 (reports August 19-20), with first delivery still targeted for the second half of 2027 - a tight but so-far-unrevised schedule given typical 12-15 month flight-test campaigns. Airbus also confirmed two divisional leadership changes already in effect this year (Lars Wagner as Commercial Aircraft CEO since January, Matthieu Louvot as Airbus Helicopters CEO since April) and a board chair transition, with Amparo Moraleda succeeding Rene Obermann on October 1, 2026. Thousands of Airbus workers in Spain resumed an indefinite strike the week of August 24 after rejecting a pay offer; on August 31 workers voted 81% to keep striking rather than suspend it, and on September 1 SIMA-mediated talks with the three unions leading the walkout (CGT, UGT, UTIL) broke down without agreement, so Airbus shifted to a parallel negotiating track with non-striking unions (CCOO, SIPA, ATP) while the indefinite strike, and its drag on production, continued into early September with no resolution yet. On the defense side, Airbus also picked up two notable wins in mid-to-late August: a $115 million U.S. Army contract (option for two more) for 10 UH-72B Lakota helicopters announced August 14, and a EUR 5.4 billion (~$6.3B) Spain-Poland framework agreement approved by Spain's Council of Ministers on August 25 for the joint procurement of seven A330 MRTT tankers (three for Spain, four for Poland) under the EU's SAFE instrument, to be assembled at Airbus's Getafe site with Polish deliveries targeted by 2030 and definitive contracts still to be negotiated. Airbus's stock has held up despite the noise, with a market cap of roughly $190B in mid-August 2026. Separately, on August 29, 2026 the Financial Times reported that Airbus is reviewing its US small-satellite manufacturing business at Merritt Island, Florida (more than 200 staff and several hundred million dollars in annual revenue), with a sale among the options; Airbus confirmed the review and said it is separate from its planned European space combination with Leonardo and Thales.

Archer Aviation logo

Archer Aviation

Civilian Aircrafts

Archer Aviation is an electric aircraft company building Midnight, a piloted four-passenger eVTOL for short urban trips, while expanding into defense, powertrain sales, and aviation software. As of Q1 2026 Archer had passed 700 Midnight test flights, completed 70% of for-credit FAA flight-test points, and formally closed FAA Phase 3 in April 2026 - the first eVTOL company to do so - unlocking Type Inspection Authorization (TIA) and entering Phase 4 (formal compliance testing). In the UAE, the GCAA transitioned Midnight to a Restricted Type Certificate (RTC) program on May 7, 2026, targeting initial commercial certification as early as Q3 2026 - meaning Abu Dhabi is likely to see the first Midnight passenger flights before the U.S. The critical remaining FAA milestone is a publicly demonstrated piloted transition flight (VTOL→forward-flight mode), which is slated for H2 2026 and had still not been publicly demonstrated as of August 30, 2026. U.S. operations are targeted for H2 2026 in Florida, New York, and Texas under the eIPP. Archer is also the named official air taxi provider of the 2028 LA Olympics. On July 15, 2026, Archer unveiled Zee, an aviation-specific AI foundation model trained on ADS-B, air-traffic, and flight data, extending its ambitions beyond air taxis into aviation software. On July 20, 2026 at the Farnborough Airshow, Archer and Anduril unveiled a jointly-developed autonomous, series hybrid-electric tilt-rotor VTOL platform - a defense variant, Anduril's Group 5 'Thunder' attack rotorcraft, and Archer's commercial 'Halo' variant - sending Archer shares up about 20%. On August 3, 2026, Korean Air - which agreed in October 2025 to become Archer's exclusive commercialization partner in South Korea for up to 100 Midnight aircraft - said it will lead conversion and systems integration of a militarized Midnight variant for South Korea's Advanced Air Mobility defense program, extending Archer's defense ambitions into an international export partnership. On August 10, 2026 Archer reported Q2 2026 revenue of $5M (up 213% sequentially, beating estimates) but a wider-than-expected GAAP loss of $0.34/share on a one-time litigation settlement; Adjusted EBITDA loss was $177M and total liquidity fell to about $1.6B, and the company held Q3 2026 Adjusted EBITDA guidance at a loss of $170-200M. Archer also disclosed that during the quarter the FAA approved its quality management system, enabling FAA-creditable conformity findings across the aircraft, its components, and systems - Archer says this makes it the only eVTOL OEM in Phase 4 of type certification with an accepted means of compliance, on top of more than 150 piloted Midnight test flights completed (some exceeding 50 miles). The same day, Archer announced a deal to acquire Boeing's Wisk Aero, Insitu and SkyGrid businesses in exchange for a Boeing equity stake of up to 19.75%, a transaction still subject to Hart-Scott-Rodino antitrust review and expected to close by year-end 2026.

Beta Technologies logo

Beta Technologies

Civilian Aircrafts

Beta Technologies is an electric aerospace company building the ALIA aircraft family, electric propulsion systems, charging infrastructure, batteries, and flight-critical systems for cargo, passenger, medical, and defense markets. Founded in 2017 by Kyle Clark, the company went public on the NYSE in November 2025 and uses a stepwise commercialization path centered on certifying its conventional ALIA CTOL aircraft first while scaling motor, charger, and engineering services. By Q1 2026, Beta had grown its aircraft backlog to 991 units worth $3.9 billion, and by Q2 2026 had logged over 190,000 nautical miles of flight testing across a 138-site charging network (targeting 250,000 nautical miles by year-end 2026). Beta was selected for seven of the eight U.S. eIPP launch programs and flew the program's first operational missions on July 10, 2026, using the ALIA CX300 to carry United Therapeutics' manufactured organs across a ~275-nautical-mile Virginia-Maryland corridor, and by August 2026 was running eIPP cargo and medical-logistics missions with partners in New York, Texas, Utah, Maryland/Virginia, and Louisiana. At the July 2026 Farnborough Airshow, Beta unveiled the MV250 - a hybrid-electric autonomous VTOL for military logistics built around a GE Aerospace CT7/T700 turbine and Sikorsky's MATRIX autonomy stack - helped GE, NASA, and Boeing complete the first hybrid-electric flight above 30,000 feet, and signed a term sheet with UK carrier Loganair for up to 10 ALIA CTOL aircraft, positioning Loganair to become Europe's first electric-aircraft airline. Q2 2026 revenue was $14.7 million (up 146% year over year, beating guidance), with FY2026 guidance raised to $42-$50 million and $1.48 billion in cash as of June 30, 2026. H500A motor certification has slipped past its original H1 2026 target, though Beta reported in its Q2 2026 results that it reached agreement with the FAA on the motor's continued-rotation compliance approach and has formal FAA testing underway; CEO Kyle Clark still targets ALIA CX300 type certification in the second half of 2027 (down from an original late-2025 goal), with the A250 eVTOL following around 2028.

Boeing is one of the world's largest aerospace companies, spanning commercial airplanes, defense and space systems, and aftermarket services. The 2026 turnaround gathered pace through the first half of the year: 314 commercial deliveries in H1 2026 (its best first half since 2018), a Q2 net loss of $428M on $24.6B of revenue that nonetheless produced the company's first positive free cash flow quarter (+$631M) in over a year, and a record total backlog of $715B including more than 6,200 commercial aircraft. The 737 MAX line reached rate 47 per month in May 2026 and gained a fourth final-assembly line - the Everett 'North Line' - in July, with rate 52 targeted for early 2027. At the Farnborough Airshow (July 20-24, 2026) Boeing booked 170+ aircraft led by SMBC's 100-jet 737 MAX order, while the long-delayed 777X neared its certification finish line even as Emirates declined to accept the first 10-11 early-build 777-9s over their age and GE Aerospace temporarily paused GE9X engine shipments pending a durability fix. The FAA certified the 737 MAX 7 on August 3, 2026, clearing the smallest MAX variant after nearly a decade of review, and on August 10 Boeing agreed to sell its Wisk Aero, Insitu, and SkyGrid subsidiaries to Archer Aviation for a near-20% equity stake. July's delivery pace cooled to 53 aircraft (down 17% from June and now trailing Airbus by 51 aircraft year-to-date, 367 vs 418), and on August 21 Boeing's roughly 17,000 SPEEA-represented engineers and technicians rejected the tentative contract their own bargaining councils declined to endorse (64.3% and 71.9% against, respectively) and authorized a strike if no new deal is reached before the current contracts expire October 6. Boeing shares fell about 7.5% on the news, cutting market cap to roughly $170B (from ~$183B in mid-August). On August 26 the FAA finalized an airworthiness directive requiring inspections of certain 787 Dreamliners over shim gaps at lower side-of-body splice plates. Boeing remains one of the two central global commercial-jet manufacturers alongside Airbus, with its trajectory now hinging on sustaining the 737 ramp without reintroducing defects, closing out 737 MAX 10 certification, avoiding an engineers' strike, and steering the 777X's remaining ETOPS testing toward 2027 certification.

Boom Supersonic is building Overture, a 60-80 seat Mach 1.7 supersonic airliner aimed at restoring commercial supersonic travel on 600+ routes at business-class economics. After XB-1 became the first independently developed jet to fly supersonic in 2025, Boom pivoted in late 2025 to make the Symphony engine and its Superpower 42 MW industrial-gas-turbine derivative the near-term commercial focus - CEO Blake Scholl said in April 2026 that roughly 90% of company efforts are now on propulsion, with Symphony and Superpower sharing about 80% of hardware. Symphony sprint-core assembly is underway at Boom's Colorado R&D supercenter ahead of a Q3 2026 sprint-core test cycle, with a fully integrated 42 MW Superpower pre-production turbine targeted for assembly by end-2026 and first Crusoe deliveries in late 2027 en route to a 1 GW-to-4 GW/year production ramp by 2030. Boom has nearly $1B in funding, a 130-aircraft Overture order book from American Airlines, United Airlines, and Japan Airlines, and a $1.25B+ Superpower launch backlog with Crusoe, while its $50M Greensboro Overture Superfactory remains largely idle ahead of a December 31, 2026 lease-termination threshold tied to a 500-employee benchmark. Two regulatory tailwinds are advancing in parallel: the FAA's proposed rule repealing the U.S. overland supersonic ban (public comment period closed August 17, 2026, final rule still targeted mid-2027) and the Supersonic Aviation Modernization Act, which cleared the Senate Commerce Committee on July 22, 2026 and awaits a full Senate floor vote that had not occurred as of August 23, 2026.

COMAC (Commercial Aircraft Corporation of China) is China's state-owned commercial aircraft manufacturer and the core vehicle for the country's indigenous airliner program. Its current aircraft family spans the in-service C909 regional jet, the in-service C919 narrow-body, and the C929 wide-body now in detailed design. COMAC has moved beyond a symbolic national program into real airline operations, customer support, and export expansion in Southeast Asia: Air Cambodia converted its 10+10 C909 commitment into a firm purchase agreement on July 17, 2026 - COMAC's first bulk order from a foreign flag carrier - and on August 12, 2026 the C919 flew its first-ever international route, Air China's daily Beijing-Ulaanbaatar service. The high-altitude C919-600 variant also completed its maiden flight on July 29, 2026. Even so, 2026 C919 deliveries continue to lag well behind the airlines' 33-aircraft annual plan, and the C919 still lacks FAA and EASA certification needed to reach Western markets.
