French M88🇫🇷 : At +800kg M88 is lighter + compact in length & width vs GE404, consider new redesign MK1A Batch with M88 engines, a direct deal of engine & spare package with or without tot, logistically will do gr8 with Rafale fleet & existing MRO Facility in Hyderabad for M88.

French M53-P2 🇫🇷 : SNECMA M53-P2 at 1.5tons despite it's age is highly reliable engine power Mirage 2000 fleet for decades, keep in mind it's a single engine fighter with excellent sortie rate, M53 makes 95KN with AB & weight 1.5ton, it's old tech but reliable, read the specs.

HAL AL-31FP 🇮🇳🇷🇺: HAL AL-31FP at +1.5tons, archiving 53% Indian by cost & 87.7% by parts & this 53% can be raised to 63%, an Indian AL-31FP derivative is feasible, If without TVC but with Indian FADEC, will be less than 1.5 ton & fuel efficient while producing +122KN with AB.

KAVERI 🇮🇳 : Needs urgent life support, this is not about just technical knowledge, AMCA till date is on paper due to lack of Indian engine, Their is no aviation without engine support from within, cannot design specific air-frame since In geopolitics their are no friends. 🇮🇳🌏

If we look at the specs chart the M88-2 itself can put 75-105kn, this is only refined in M88-3,4 & increased in T-Rex perhaps, the M88 is a fine engine including Navy fighters, a deal of nos of engine with spares be tot or without it would save the boat. https://x.com/DefenceDecode/st...

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Redesign means a new cycle of certification and years of further delay. Isn't it.

@Vaishvamitra @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Yes, but this will be better than scraping or grounding entire fleet with no future to fly back, Iranians F14 ditched their GE engines for AL-31 to keep flying ..

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 AL-31FP is in a different thrust class. It cant be used on Amca and Tejas mk2.

@Ray70409890 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Close to F110, good alternative for lot of projects, but require few improvements ..

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Do we need redesign the body of LCA for different engines !!!

@75Sukhoi @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Yes, it require deep modification be it any engine .. The smaller engine or same dimension of GE-404 is a good news but if bigger you need alot of R&D with serious changes to airframe, like if we want AL-31 variant on Tejas.

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Indian LCA Tejas: Could the RD-33MK Replace the GE F404? https://youtu.be/cDimfnS-Xq8

@75Sukhoi @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 RD-33-3 looks good on paper but is often flame-out, have less life hours on it and basically a kind of engine meant to use & throw, Russian philosophy of engines is different than our and west.

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 @grok bro ye saara data dekho aur ye batao ki two kaveri engines ke sath Tejas MK2 bnana kitna difficult hai? Also interms of timeline, abhi jo F414 ke sath Tejas MK2 bana rahe hai, uski jagah twin Kaveri krne se timeline kitni affect hogi? Realistic.

@Kunal_Biswas707 @Defencematrix1 @raflanker @Firezstarter1 M53 production line is closed, same situation as GE F404.

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Let current AMCA happen...since v will anyway get GE414 deal....As of today, v r not going back.worst case, v wont get any ToT. 1.But, make sure that : GTRE-SAFRAN enigne come by 2035 2.Kick start a new 5th Gen fighter designed around AL51F1

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 3rd option isnt feasible AMGB on top and for others it is below

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Make AMCA Big so that in future it will not face a bottleneck. Indians love everything medium and small 🤡 and a new citcus will be initiated in future by IAF that they need a bigger aircraft to accomodate longer missiles.

@Kunal_Biswas707 @Defencematrix1 @raflanker @Firezstarter1 How true is 29.5 KN kaveri afterburner news. Did BATL get the contract, when is the delivery?

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 Love to see RD93 on Tejas .. JF17 and Tejas on same team

@Kunal_Biswas707 @Defencematrix1 @raflanker @Firezstarter1 Just reverse engineer F - 404 and show middle finger to the yankees

@Kunal_Biswas707 @Defencematrix1 @ReviewVayu @raflanker @Firezstarter1 The old Kaveri, in pairs, surely we can have them pairs in a next-gen MiG-29 derivative, can't we?
