Komatsu has unveiled an autonomous electric underwater tractor capable of operating at depths of 7 meters, with plans to reach depths of up to 50 meters in the future. The innovation aims to transform underwater construction by offering more efficient and sustainable solutions for marine projects.
Japanese construction equipment giant Komatsu has surprised by unveiling an innovative all-electric underwater bulldozer at the CES 2025, the world's largest consumer technology event, in Las Vegas. The tractor was one of the highlights of the event.
The presentation marked the company's debut at the fair and brought with it an impressive combination of innovation, sustainability and story.
Innovation inspired by the past
According to the Komatsu team, the tractor prototype is an evolution of a mechanical model created in the 1970s, which was powered by diesel.

The new version reflects current demands for more sustainable technologies, operating exclusively with electrical energy.
The underwater tractor can work at depths of up to seven meters, but the company is developing technologies to expand this capacity to 50 meters in the near future.
With a 450 kWh battery, expandable to 500 kWh, the bulldozer has autonomy for six hours of continuous operation.
The recharge time is just four hours, allowing its use in critical tasks such as river dredging, ecosystem restoration and natural disaster prevention.
Impact on industry and sustainability
Taisuke Kusaba, CTO and President of the Development Division of Komatsu Ltd., highlighted the importance of the event for the company. “CES offers us a unique opportunity to showcase innovations that are shaping the world around us. Our underwater bulldozer reflects our commitment to sustainability and technological advancement.”, He stated.
Komatsu’s initiative is in line with the growing demand for sustainable solutions in sectors such as construction and mining. By replacing combustion engines with electric systems, the company contributes to reducing emissions and promoting a cleaner future.
First physical exhibition and technologies of the future
In addition to the underwater bulldozer, Komatsu brought its first physical display of lunar construction equipment to CES 2025, reinforcing its position as a leader in extreme technologies.
The company's stand at West Hall do Las Vegas Convention Center is designed to attract not only investors and partners, but also young talent who can shape the future of engineering and automation.
Hiroyuki Ogawa, President and CEO of Komatsu Ltd., stressed the importance of attracting new generations. “The construction and mining industries employ some of the most advanced technologies, but we need talent who see the opportunities for innovation in these areas"He said.
Design and technical challenges
The underwater bulldozer presented is a clear example of how Komatsu seeks to overcome complex technical challenges. Currently, the equipment faces limitations related to the use of GPS in underwater environments.
However, the company is investing in the development of solutions that allow greater precision and range, even in adverse conditions.
The choice of electrical energy also presents challenges, especially with regard to energy efficiency and durability in submerged environments.
Despite this, Komatsu demonstrated confidence in its ability to adapt existing technologies to meet the specific demands of this segment.
A century of innovation
Founded 103 years ago, Komatsu is widely recognized for its expertise in heavy equipment. The company operates in more than 150 countries and serves a wide range of industries, including construction, mining, forestry and industrial.
Its commitment to innovation has been one of the pillars of its longevity, allowing it to adapt to market changes and new global demands.
Throughout its history, Komatsu has established a global service and distribution network to provide technical support and increase the productivity of its customers.
These partnerships have been fundamental to the development of solutions such as the electric underwater bulldozer.
Global engagement and career opportunities
Participation in CES 2025 is also a strategy by Komatsu to strengthen its global presence and attract talent.
The event, which brings together thousands of companies and innovators, provides a unique platform to demonstrate the relevance of their technologies on a global stage.
"CES is more than a product showcase; it’s an opportunity to connect with the future”, commented Kusaba. He reinforced that the goal is not only to showcase technological advances, but also to inspire the next generation of engineers and designers.
A new era for underwater equipment
The transition to electric equipment marks a new era for Komatsu and the heavy construction industry as a whole.
The application of advanced technologies in underwater contexts opens doors to projects that were previously limited by environmental or logistical issues.
Expectations for the development of the underwater bulldozer include not only improvements in battery life and range, but also the integration of artificial intelligence systems for autonomous operation.
These advances could revolutionize the way infrastructure projects are conducted in complex environments.
It was about time to have information of this size and importance. Technological advances give us companies like this. We have been on Mars for so long.
Komatsu has always been visionary, I spent wonderful years of my life (18) at Komatsu Suzano
I, who sounded like a technician, thought, I hope the businessmen who buy it at least take it out of the water to fix it.
