In an surprising move, SAFRAN announced a 20% thrust improvement to the M88 engines on Rafale Fighter Jet
As far as I remember, Dassault Jet's like Mirage III, Mirage F1, Mirage 2000 and Rafale have never seen an improvement of the engine thrust in there service live. Once installed, nothing will be made - never change an working system.
Until now - the French Doubledelta Fighter will receive new engines called M88 T-REX with 20% more thrust and maximum compatibility to the actual M88 engine. The upgraded engine will be implemented on Rafale Standard F5, beginning in 2030.
First user will be the French Navy, with 12 Rafale F5 Marine in the 6th command for delivery in between 2030-2034. India will receive there first Rafale M in 2028, actually it's not clear if it will also be F5 standard - expected is an integration as fast as possible.
External changes to actual Rafales are expected on the air inlet. With the production of more electricity on the new engine, internal systems can be optimized and improvements on radar, electronic countermeasures and other systems are possible. The F5 version has a lot of internal improvements already, for example another wiring and more capable computers and systems. Rafales of the future will be the 'old' F4.1 and the new F5 type - the new engine can be used on the old version (possibility exists, but it's not planned for French Armed Forces yet) but some other modifications of the F5 standard are not possible.
The new engine will also be of interest for Gripen and Tejas - especially to cancel all US parts in those aircrafts.
