This firefighting aircraft promises to do it all – amphibious, pilotless, day and night ops, fleet coordination and an AI brain.

Marcos Aerospace, a Greek aerospace startup based in Athens, has just launched Quencher, an autonomous amphibious aircraft currently in what the company is describing as “the preliminary design phase.”

With a 4,500-litre water capacity, Quencher is designed to conduct high-frequency aerial firefighting operations both day and night. Marcos Aerospace says patent application covering the platform’s core innovations have been filed.

The company announcement describes Quencher as “a deep-tech aerial firefighting platform”.

“Quencher integrates AI-assisted navigation, automated mission management, autonomous flight controls, and swarm coordination capability. The aircraft is optimized for continuous scooping operations from seas and lakes, as well as rapid refilling at designated ground stations, enabling relentless, around-the-clock initial attack and wildfire suppression,” according to the media release.

“Quencher is not merely a new aircraft; it represents a paradigm shift and a new category in aerial firefighting,” said Marcos Caramalengos, aerospace engineer and founder of Marcos Aerospace.

The Marcos Aerospace website provides some more detail. One operator can coordinate up to five Quencher aircraft simultaneously.  Maximum speed is 440km/h, cruise speed is 360 km/h, built around a Pratt and Whitney PW127 turboprop engine.

A clarification of its current status on the website shows the concept is still in its very early days: “Quencher is under development. The aircraft, systems, and operational concepts described on this site reflect the current design intent and program direction. Certification, testing, and operational deployment will follow applicable regulatory and safety requirements.”

Quencher is in Pre-Production Development Phase (2026–2029), which includes the design, engineering, and certification of the Quencher aircraft ahead of first production and commercial launch.

Marcos Aerospace says it is now open to strategic partnerships and discussions with civil protection authorities, industry stakeholders, and investors.

China manufacturing large amphibious air tanker

China is manufacturing a large air tanker that will be amphibious, able to land and takeoff from an airport or the sea. It will have a 3,000-gallon water capacity, four turboprop engines, able to handle a wave height of two meters, and will have a maximum speed of 354 mph (570 kph, 308 knots). The base model for the aircraft is the AVIC TA-600 which is designed to be used for transport, water rescue, or to carry up to 50 passengers. The air tanker version appears to have the AG-600 model name. Both aircraft are similar to what was then known as the JL-600 when we wrote about it in 2010 at Wildfire Today.

The maiden flight is expected to take place in the first half of 2016.

Below is an excerpt from an article at ChinaDaily:

“The AG-600 will meet China’s urgent need for such equipment in forest fire control and maritime search and rescue, and it will form an important part of the country’s emergency response and rescue system,” Huang Lingcai, chief designer of the aircraft at the Zhuhai company said.

Powered by four turboprop engines, the AG-600 will become the world’s largest amphibious aircraft, surpassing Japan’s ShinMaywa US-2 and Russia’s Beriev Be-200, the designer said.

The AG-600, formerly known as the D-600, will have a maximum takeoff weight of 53.5 metric tons and an operational range of about 4,500 km. It can be used for a variety of operations, such as passenger and cargo transport, resource surveys as well as marine environmental monitoring, in addition to its foremost tasks of firefighting and maritime rescue, according to Leng Yixun, director of general aviation products at AVIC.

“The seaplane’s major users will be government departments such as forestry authorities, the coast guard and maritime safety bureaus. We estimate our country will need at least 100 such seaplanes within the coming 15 years,” he said.

He added that his company has received 17 orders from domestic customers, including several private general aviation enterprises.
