Range

I keep reading about 200 km electric range everywhere. If this is the maximum range, how could this plane ever be certified to carry passengers? There are rules to have sufficient fuel for holding at the destination and diverting to an alternate airport. This alone is way more than 200km... Does anybody have information how this huge problem is meant to be solved? Is the 200 km figure some sort of "net value with reserves"? — Preceding unsigned comment added by 2A02:B98:4736:E710:36D1:9EC4:401:8CD0 (talk) 16:14, 31 May 2023 (UTC)

Company has moved to Los Angeles

Hello. The company has moved to California and no longer has a presence in Sweden. This should be reflected in the article, but as I work for the company, I understand that I should get community input before making any changes. I’ve compiled a list of updates with sources for your convenience, but would be happy to make the changes myself if that’s easier:

• The short description should be changed to reflect that they are an airplane manufacturer.
• The infobox should reflect the company’s headquarters in Los Angeles, California.
• The lead should also say that Heart Aerospace is an aerospace manufacturer making electric aircraft that is based in Los Angeles.
• The company overview can read: Heart Aerospace was founded in 2019 by Anders and Klara Forslund in Gothenburg, Sweden. In 2024, the company maintained headquarters in Gothenberg and a research and development facility in California. By 2025, the company had moved the headquarters and all operations to Los Angeles.
• In the History section, I suggest editing the last paragraph to read: In May 2024, Heart Aerospace announced the establishment of a new research and development hub in Los Angeles and the Forslunds moved there to oversee operations. In 2025 the company closed their Swedish operations and moved their headquarters to Los Angeles.

Thanks so much. I'm pinging RickyCourtney who looks like he's been actively working on this article. HeartA25 (talk) 13:18, 29 July 2025 (UTC)

Thanks for the edit request, HeartA25. I've made the updates you requested, along with some layout tweaks of my own. Please feel free to post here again if you require any further changes, though for your next major request I recommend adding the {{edit COI}} template (as I have done at the top of this section) to ensure it can be more easily seen and answered. Thanks! Yeeno (talk) 04:54, 30 July 2025 (UTC)

Thanks Yeeno for your response and advice. I am looking into other changes that can be made and will use the template as suggested. I look forward to future work on this article! HeartA25 (talk) 02:30, 1 August 2025 (UTC)

Updates to the Products section

Hello, I noticed a couple of things missing from the product section. I suggest renaming the section as "Aircraft" and adding the following:

• Heart Aerospace’s first design, the ES-19, was unveiled in 2020 following their participation in the 2019 Y Combinator’s Winter Batch. The ES‑19 was a 19‑seat, all‑electric regional aircraft concept designed for short-haul routes of approximately 250 miles (400 km). In June 2022, the company changed their application to a heavier weight category and EASA CS-25 certification which would not require an exemption from the European Union Aviation Safety Agency for being overweight. This design was then superseded in September 2022 by the ES-30.
• Development of the ES 30 is partially funded by a $4.1 million FAST grant from the Federal Aviation Administration for the design of hybrid engine control systems.

I also uploaded a number of photos to Wikimedia Commons in the Heart Aerospace category. I added two to the page, but there are others if anyone wants to take a look and see if more of them are relevant.

I'm pinging Yeeno who was so helpful last time, and I appreciate everyone’s input. Thanks! HeartA25 (talk) 17:23, 10 September 2025 (UTC)

Proposed finances section

Hello, I changed my username to better meet Wikipedia username guidelines, but I am the same person as HeartA25 above. I appreciate everyone's efforts to update this article so far, especially Yeeno who helped implement a few of my previous ideas.

I had thoughts about how to better incorporate financial information about Heart Aerospace, and I suggest creating a Finances section with the wording below. I moved a couple sentences from the History and the Aircraft sections. I am happy to explain more or delete any redundant information myself once a new Finances section has been created, whatever is easiest. I was also unsure about whether the chart that is currently on the page belongs in History or Finances, so an editor may want to look at that as well.

Proposed finances section

Finances

In the spring of 2019, after participating in Y Combinator, Heart Aerospace raised $2.1 million USD in seed funding led by EQT Ventures, the Norrsken Foundation, and Chris Sacca’s Lowercarbon Capital. By March 2021, the company documented interest in their concept airplane, the ES 19, from Finnair, the NEA, and airlines in New Zealand, Canada, the US, and the UK.

The company secured $35 million USD in Series A funding in July 2021, led by Bill Gates' Breakthrough Energy Ventures, United Airlines Ventures, and Mesa Air Group, with participation from existing seed investors EQT Ventures and Lowercarbon Capital. At that time, United Airlines Ventures and Mesa Air Group also announced an order of up to 200 ES-19 planes.

In September 2022, Air Canada and Saab each invested $5 million in Heart Aerospace. Concurrently, Air Canada placed a purchase order for 30 ES-30 aircraft. Prior orders for the ES-19 from United and Mesa Air Group were converted to the ES-30. The company also confirmed letters of intent and orders from Nordic operators like SAS AB, Braathens Regional Aviation, Icelandair, up to 40 planes for Rockton Sustainable Aviation, and an order from Sounds Air in New Zealand. By the end of 2022, Heart Aerospace had secured 230 orders for the ES-30.

In February 2024, Heart Aerospace raised a total of $107 million in Series B funding, increasing its total capital raised to $145 million. Investors included the European Innovation Council Fund and Sagitta Ventures, a Danish early-stage investment firm, as well as some returning investors like Air Canada, Breakthrough Energy Ventures, EQT Ventures, Lowercarbon Capital, Norrsken VC, United Airlines, and Y Combinator.

In 2024, the Federal Aviation Administration selected Heart Aerospace to receive a $4.1 million FAST grant to support the design of hybrid engine control systems.

Heart Aerospace raised $40 million from an existing investor in the spring of 2025. By the fall of 2025, the company had raised more than $185 million USD in venture funding. It also had 250 orders for the ES-30, and options or purchase rights for an additional 120 planes.

Additions to the History section

Hello everyone. I removed the redundant information from the History and Aircraft sections that are now in the Financing section. There are a number of pieces of history that I noticed are missing from that section and create a more complete picture of the company's work. Below are my suggested additions if Likeanechointheforest, Yeeno, or another member of the community would like to take a look.

• Following the first sentence in the section, I suggest adding:

They set up operations at Säve Airport near Gothenburg.

• After that opening paragraph, I suggest the following paragraphs:

The company participated in the 2019 Y Combinator’s Winter Batch and subsequently unveiled their design for the ES-19 all‑electric regional aircraft.

In January 2022, Heart Aerospace conducted a successful test flight with a one-fifth-scale model of it’s ES-19 airplane. Then, in September 2022, the company changed direction and unveiled the ES-30 which was a slightly larger hybrid-electric powered regional airliner. They also announced an Industry Advisory Board with members representing airlines, leasing companies, and airports.

In 2024, Heart Aerospace unveiled the Heart X1, its first full-scale demonstrator aircraft, as a development tool for the ES30. They also announced plans for their first test flight at Plattsburgh International Airport followed by the X2 prototype. In September 2024, Heart Aerospace filed two EU design applications and one patent application for their integrated nacelle design. That same year, they were also awarded a FAST grant from the FAA for the design of hybrid engine control systems.

• The R&D hub in LA is specifically focused on the development of the propulsion system. In the last paragraph of the section, I suggest adding this information to the first sentence:

In May 2024, Heart Aerospace announced the establishment of a new research and development hub in Los Angeles focusing on their hybrid-electric propulsion system and the Forslunds moved there to oversee operations.

Simple cleanup for the Aircraft section

Thank you Yeeno for all your work on this page. Looking at it now, I have some small suggestions for the Aircraft section. At the bottom, I've included what this could look like and included all the sources.

• Split the section with subheadings by aircraft.
• To the subsection about the ES-19, I suggest adding:

• The company conducted a successful test flight with a one-fifth-scale model of the plane in January 2022 that lasted four and a half minutes with a maximum speed of 93 mph.

• Add some top-tier third-party sourcing about the ES-30 to support content already on the page.
• To the subsection about the ES-30, add the following content:

• The ES-30’s design includes batteries for shorter routes and two turboprop engines to extend flight range. It also features Heart Aerospace’s design for an engine nacelle integrated into the wing which will allow the plane to fly at lower speeds and operate on shorter runways.
• The plane is projected to have a per-seat operating cost similar to a 50-person propeller plane.

• To the subsection about the X1, I suggest adding:

• In 2024, Heart Aerospace unveiled its first full-scale demonstrator aircraft, the Heart X1 (Heart Experimental 1), to test systems and technologies for the ES-30. It features a fully composite fuselage and has a 105 ft wingspan. Development of the X1 was partially funded by grants from the Swedish innovation agency Vinnova.

Aircraft

ES-19

Heart Aerospace’s first design, the ES-19, was unveiled in 2020 following their participation in the 2019 Y Combinator's Winter Batch. The ES‑19 was a 19‑seat, all‑electric regional aircraft concept designed for short-haul routes of approximately 400 kilometres (250 mi). the company conducted a successful test flight with a one-fifth-scale model of the plane in January 2022 that lasted four and a half minutes with a maximum speed of 93 mph.

ES-30

Heart Aerospace founder and CEO Anders Forslund showcases a cutaway rendering of the ES-30 hybrid-electric regional aircraft and its propulsion system in 2024.

The ES-30 is a 30-seat hybrid-electric powered regional airliner, designed for enhanced sustainability and efficiency on short-haul routes. It is projected to have an electric-only range of 200 kilometres (110 nautical miles) and a hybrid-electric range of 400 km (220 nmi), significantly reducing carbon dioxide emissions compared to conventional aircraft on similar routes. With a reduced passenger load of 25, a range of 800 km (430 nmi) may be achievable.

The ES-30’s design includes batteries for shorter routes and two turboprop engines to extend flight range. It also features Heart Aerospace’s design for an engine nacelle integrated into the wing which will allow the plane to fly at lower speeds and operate on shorter runways. Development of the ES 30 is partially funded by a FAST grant from the Federal Aviation Administration. The company aims to achieve type certification for the ES-30 by the end of the 2020s. The plane is projected to have a per-seat operating cost similar to a 50-person propeller plane.

Experimental Planes

Ground crew conducts a turnaround test of Heart Aerospace’s X1 prototype, loading baggage and preparing the aircraft for simulated flight in September 2024.

In 2024, Heart Aerospace unveiled its first full-scale demonstrator aircraft, the Heart X1 (Heart Experimental 1), to test systems and technologies for the ES-30. It features a fully composite fuselage and has a 105 ft wingspan. Ground testing was completed in Gothenburg in 2024, with flight testing planned at Plattsburgh Airport in New York. Development of the X1 was partially funded by grants from the Swedish innovation agency Vinnova. The X1's maiden flight, powered solely by electricity, was anticipated in the second quarter of 2025. This has not happened as of the third quarter of 2025.

Following the X1 program, Heart Aerospace plans to construct a pre-production prototype, the Heart X2. The X2 will incorporate design refinements based on the X1's operational experience and will feature the company’s hybrid propulsion system, which is slated for a hybrid-electric flight demonstration in 2026.

 Done I couldn't verify the "fully composite fuselage" in these sources, but the rest is done. Fiske (talk) 21:23, 12 May 2026 (UTC)
