Saft, a subsidiary of TotalEnergies and a global specialist in advanced battery technology, has been awarded a major contract by Naval Group to supply next-generation lithium-ion (Li-ion) battery systems for the Barracuda and Scorpene submarine families.
Saft press release
This award represents a strategic milestone for Saft, strengthening its position in European defense programs and confirming the growing demand for its advanced Li-ion battery technology, thanks to high-performance and reliability in top-end naval applications.
A breakthrough in submarine energy systems
Saft’s Li-ion batteries, based on proprietary cells developed and manufactured in-house, deliver a step change compared to lead-acid technologies:
- Higher energy density, enabling longer underwater endurance
- Enhanced operational performance and mission flexibility
- Total operational safety, meeting the most stringent defense requirements
This achievement is the result of several years of close collaboration between Saft and Naval Group.
This strategic partnership highlights the strength of European industry, bringing together two leading players to develop and deliver critical, high-performance technologies within Europe.
It supports the growing need for sovereign defense capabilities while opening the way for future international programs.
Saft’s expertise at the core of the project
A key differentiator behind this contract is Saft’s ability to master the entire battery value chain, starting from the core of the technology: electrochemistry. For more than 100 years, the company has delivered highly reliable solutions for critical applications where safety and performance are essential.
“This contract confirm that advanced battery technology is now a defining factor in submarine performance. Our Li-ion systems set a new standard in energy density, safety and reliability, positioning Saft at the heart of next-generation naval defense programs. This is also a clear step forward for European technological sovereignty.”
Cedric Duclos, Chief Executive Officer of Saft
“Integrating Saft’s Li-ion technology onboard the Barracuda and Scorpene submarine families is of great value, allowing us to enhance performance at sea.”
