Hanwha Aerospace Ends $318M VX4 eVTOL Supply Deal

This article summarizes reporting by Yonhap News Agency by Kim Boram.

South Korean supplier Hanwha Aerospace Co. and United Kingdom-based Vertical Aerospace Ltd. have mutually agreed to terminate component supply contracts for the VX4 electric vertical takeoff and landing (eVTOL) aircraft, ending a partnership originally valued at 454.8 billion won ($318 million).

The termination, signed on July 31, 2026, and announced in a regulatory filing on August 3, 2026, reflects broader timeline adjustments within the Advanced Air Mobility (AAM) sector. According to Yonhap News Agency, Vertical Aerospace initially targeted 2025 for the commercialization of its four-passenger VX4 air taxi. Industry-wide certification delays and shifting investment climates have since forced major aerospace suppliers to reassess their commitments.

Scope of the terminated VX4 agreements

The canceled agreements encompassed two major systems for the VX4. The initial contract, signed on August 23, 2022, covered the development and supply of Electric Motorized Actuators (EMA) and was valued at approximately 219.2 billion won. In October 2023, the partnership expanded with a 235.6 billion won contract for tilting and blade pitch systems.

BigGo Finance reported that the combined 454.8 billion won deal represented approximately 7.09 percent of Hanwha Aerospace’s consolidated revenue for the 2021 fiscal year. The original supply arrangement was scheduled to run through 2036, according to Maeil Business Newspaper (MK).

Despite the termination, the hardware had already reached the testing phase. Vertical Aerospace previously announced in July 2024 that its next-generation full-scale VX4 prototype, which commenced piloted flight testing, featured components supplied by Hanwha Aerospace.

Strategic realignment and future cooperation

The decision to end the supply contracts was driven by changing market realities rather than performance failures. A Hanwha Aerospace official told ChosunBiz that both companies had faithfully fulfilled their obligations. The official noted that the mutual termination was based on a strategic judgment, citing changes in market conditions and business direction compared to the original purpose of the partnership.

Speaking to MK, another company representative stated that Hanwha Aerospace is adjusting its Investments priorities based on a comprehensive review of market conditions and business viability.

The relationship between the two Manufacturers has not been entirely severed. On July 31, 2026, alongside the termination agreement, Hanwha Aerospace and Vertical Aerospace signed a new Memorandum of Understanding (MOU). MK reported that this MOU establishes a framework for potential future collaboration on development projects and mass-production supply once AAM market conditions stabilize.

AirPro News analysis

We view this contract termination as a pragmatic recalibration rather than a sudden collapse of confidence in Vertical Aerospace. The AAM sector is currently navigating a difficult transition phase characterized by prolonged regulatory certification paths and a tightening global investment environment. By converting a binding, capital-intensive supply contract into a flexible MOU, Hanwha Aerospace limits its near-term financial exposure while maintaining a foothold in the eVTOL market. For Vertical Aerospace, the dissolution of the 2036 supply timeline underscores the reality that initial commercialization targets, such as the original 2025 goal, were overly optimistic given the regulatory hurdles facing novel aircraft architectures.
