On November 22, 2025, AutoFlight Aviation Technology unveiled the world’s first “Integrated Sea-Air Low-Altitude Economy Solution.” The system comprises a zero-carbon Water-based Green Vertiport (WGV) that extends eVTOL infrastructure across vast water areas, addressing key challenges such as difficult site selection, slow deployment, and complex take-off and landing operations.
This advancement accelerates the transition of the low-altitude economy from blueprint to large-scale application. The solution supports five major use cases: energy platform maintenance, emergency rescue, high-frequency commuting, marine-aerial tourism, and mobile vertiport clusters, paving the way toward a new era of integrated land-sea-air transport.
Water-based Green Vertiport, Deployable Across Waterways
AutoFlight’s self-developed, world-first Water-based Green Vertiport serves as a mobile aerial hub and intelligent command center on water. It integrates eVTOL landing platforms, photovoltaic energy storage and charging systems, an intelligent dispatch system, and communication facilities, enabling rapid deployment across rivers, lakes, and seas.
Designed specifically for eVTOL operations, the vertiport is fully electric. Its spacious deck serves as a landing pad covered with solar panels, while the cabin acts as a departure lounge and technical room. Together, these components form a flexible, zero-carbon vertiport that supports take-off, landing, and charging for eVTOLs, while also enabling data sharing and intelligent coordination with the aircraft.
As the low-altitude economy continues to grow, the limited availability of eVTOL infrastructure remains a bottleneck, with land-based vertiports often facing lengthy construction timelines. The water-based vertiport is compatible with several of AutoFlight’s key eVTOL models—including the industrial-grade “White Shark,” the 2-ton-class cargo aircraft “CarryAll,” and the 6-seat passenger model “Prosperity.” Together, they form an integrated land-sea-air solution that enables rapid point-to-point transportation across a wide range of scenarios.
Synergizing Sea and Air, Reshaping Five Key Sectors
Leveraging the White Shark, CarryAll, and Prosperity eVTOLs, the Integrated Land-Sea-Air solution addresses a variety of sectoral needs, enhancing operational efficiency and fostering synergy between the low-altitude and marine economies:
- Marine Energy Platform Maintenance: For offshore oil rigs or wind farm operations, the solution improves the transport efficiency of personnel and critical spare parts by over tenfold.
- Emergency Response: By combining wide-area search capabilities with rapid eVTOL response, the system reduces reaction time by over 50%, expands search coverage significantly, increases survival rates, and enhances responder safety.
- High-Frequency Commuting: It enables rapid air transit within cities, between coastal city clusters, across bay areas, and to islands, reducing travel time from hours to minutes. For instance, deploying an eVTOL water vertiport on Shanghai’s Huangpu River could facilitate swift, convenient travel from Hongqiao airport to Lujiazui, Shanghai’s central business district, without disrupting existing infrastructure.
- Marine-Aerial Tourism: Adds a “flight+” dimension to high-end tourism, creating a new engine for experience-driven tourism.
- Mobile Vertiport Clusters: Multiple mobile water vertiports can be rapidly networked within a specific water area to form a high-throughput, distributed vertiport cluster, supporting large-scale, multi-mission coordinated operations for broader coverage and smarter applications.
Pioneering a New Paradigm of Zero-Carbon Integrated Land-Sea-Air Transport
Amid a global shift toward sustainable transportation, zero-carbon aviation has become a critical frontier. By leveraging under-utilized water surfaces, AutoFlight’s solution introduces a highly adaptable, low-impact urban air mobility model. It enables coastal and waterside cities worldwide to rapidly deploy green aviation infrastructure, transforming rivers, lakes, and coastal zones into hubs for clean, efficient transport.
Developed in collaboration with strategic partner and investor CATL, the solution integrates high-safety batteries and clean energy systems into both the eVTOLs and water vertiports. This partnership advances the development of a truly carbon-neutral aerial ecosystem. Together, the companies are accelerating the real-world application of emission-free air mobility, moving beyond traditional land-based systems toward a more connected and sustainable future integrating land, sea, and air.
First Public Flight Demonstration of the Integrated Sea-Air Solution
On the afternoon of November 22, the Integrated Sea-Air solution was publicly demonstrated for the first time at Dianshan Lake in Kunshan. A 2-ton-class eVTOL aircraft took off from the Water-based Green Vertiport, showcasing the collaborative operational capabilities of the water-based vertiport and eVTOL under this innovative “water + low-altitude” model.
AutoFlight also conducted a multi-aircraft formation flight demonstration, in which three 2-ton-class eVTOLs flew in formation and successfully performed live airdrop missions—including deploying supplies and life rafts. The demonstration fully illustrated the application potential of eVTOLs in fields such as emergency response and low-altitude logistics.
