M88 was studied as a familly :
M88-2 : serially produced for Rafale.
M88-3 9Tons variant. Built and tested as prototyps (for UAE in a time, 2011, were they wanted a kind of super Rafale.
M88-4 : 10.5 Tons. Only a paper project.... except if it is this engine that is expected to power the SCAF prototyp. But between 2 prototyps to manually built for SCAF proto and a production line, SAFRAN need time. Not sure it is possible to meet Tejas 2 agenda.
There is also T-Rex M88 for Rafale F5.... no news so far, except that it is more and more evident that F5 will keep the actual Rafale frame, ie the T-Rex will ave the same overall dimensions than M88-2. Sure that new technologies will make T-Rex more powerfull than Legacy M88-2, but at what extent ? Not in the 98 KN league for sure.
