HLFT-42 Lead-In Fighter Trainer: News & Discussions: 02 August 2022

Does the IAF need an attack aircraft?
Does today’s battle space and weapons avaiable warrant an attack aircraft?

I Think it’s a LIFT + Low cost attack aircraft for the export market . While I am all for desi design and development this is a solution looking for a problem developing a whole new aircraft will be expensive and will need to solve many challenges. Just look at the time python took and now Astra integration is taking . Btw the Astra launcher needs optimization. We should go all in on LCA and use the trainer as lift for our needs . Use the time and money to keep refining LCA

It's for export. IAF need not buy this.
It's below their dignity.

Whats the new wing area vs the old wing area of 38.4 sq m?
9.0/8.2= 1.097 say 10% more just from span increase?
And another 5% more for the root length.
So about 15% more in 38.4*1.15 ~44 sq m?
