Safran Unveils M88 T-REX Engine with Enhanced Thrust for Next-Gen Rafale Fighter

French aerospace company Safran has introduced a powerful evolution of its proven M88 engine — the M88 T-REX — at the Paris Air Show, targeting future upgrades of the Dassault Rafale fighter jet. Designed to meet the needs of evolving combat scenarios and next-generation warfare, the new engine promises a significant leap in performance while retaining the compact and efficient characteristics of its predecessor.

The M88 T-REX, short for "Thrust REXtended," is an advanced version of the M88 turbofan engine currently powering all variants of the Rafale. With its upgraded configuration, the T-REX delivers a remarkable 9 metric tons of thrust with afterburner — a noticeable increase over the current M88-2’s 7.5 tons. This added power is aimed at enhancing the aircraft’s acceleration, climb rate, and payload capacity, especially in future high-intensity missions.

Key improvements in the M88 T-REX include:

• An improved low-pressure compressor to increase airflow and overall engine efficiency.

• A high-pressure turbine made with cutting-edge materials and enhanced cooling technologies, enabling it to withstand higher operating temperatures.

• A redesigned engine nozzle with better aerodynamic flow, contributing to thrust efficiency and fuel economy.

Despite the enhancements, Safran has ensured that the T-REX maintains critical advantages of the M88 family — such as modularity, compact size, and ease of maintenance. The company has emphasized that many of the T-REX’s modules will be interchangeable with those of the current M88 engines, making upgrades across existing Rafale fleets more cost-effective and logistically smooth.

Safran has already started risk reduction studies for the T-REX, laying the groundwork for a full development phase. The new engine is expected to be certified in time for the Rafale F5 standard — the next major upgrade of the multirole fighter, which is projected to include improved sensors, network-centric capabilities, and optionally manned operation.

Christophe Bruneau, Executive Vice President of Military Engines at Safran, highlighted that the M88 T-REX is not just a performance boost but a strategic investment in technology and sovereignty. He noted that this project would feed innovations across Safran’s broader engine portfolio while aligning with France’s goal to maintain control over its key defense technologies.

As global security dynamics continue to shift, the M88 T-REX positions the Rafale to remain a competitive and capable fighter well into the future — with greater power, flexibility, and operational efficiency.
