Kaveri to Tejas Delays: Crisis of India's Missing Jet Engine |S3| 40

In Our Defence

Show Notes

How is that India, a country capable of sending probes to the dark side of the Moon, still struggles to build a fighter jet engine?

With the deliveries of the Tejas Mk1A delayed due to supply chain issues with the GE F404 engines, the spotlight is back on India's critical vulnerability: we don't have a heart for our fighter jets.

In this episode of In Our Defence, host Dev Goswami and defence and national security expert Sandeep Unnithan sit down to demystify the magic of jet engine technology.

From the "Suck, Squeeze, Bang, Blow" basics to the high-tech world of Single Crystal Blades and metallurgy that operates above melting points, the two break down exactly why this technology is the exclusive domain of just a handful of nations.

The episode also digs deep into the history of the DRDO's Kaveri engine project. Was it really a failure and was putting it on the backburner a mistake? Plus, what can we expect from the upcoming mega-deal with France's Safran for the AMCA's engine?
