Many defence enthusiasts and Experts thinks' ORCA(Is not even in papers) and TEDBF is a waste of money , and India should consider importing more Rafale for Airforce and a Naval Aircraft for under development INS Vikrant'. Some want India to procure stealth Aircrafts by avoiding 4th generation Aircraft.
But in our opinion India should go on with both TEDBF and ORCA . In future(within 10-15 years) we need huge quantities of fighter jets to counter Chinese and Pak Airforce and also to replace Su 30 MKI , Mirage ,Mig 29 and Jaguar.
Let's look at the current strength of Chinese Fighter Aircraft (4th and 5th).
Su 35 -24
Su 30 MKK- 76
Chengdu J10 - 500+
Shenyang J11-346
Shenyang J16- 128
Chengdu J20 - 20
Total- 1100 plus
--------------------------------------------------------
Pakistan Airforce :
Mirage - 180
F16- 76
JF 17- 107
Total -363+
----------------------------------------------
Indian Airforce:
Su 30 MKI -272
Mig 29 UPG- 66
HAL Tejas - 16 (16 More)
Rafale - 36 in order
Jaguar - 90
Total -450
----------------------------------------------------
Indian Airforce outnumbered in 3 to 1 if you add 3+ generation Aircraft in this then it is even worse for IAF.
Both China and Pakistan adding more and more 4th and 5th generation Aircraft's rapidly. in 2030-35 we can assume Chinese will have 1500 modern 4th and 5 th generation fighters . Pakistan will have 500 4th generation Aircraft's, fifth generation J31 from China may find a place in PAF.
To counter this grave threat India need atleast 1000 4th and 5th Aircraft's .
We will have AMCA as a 5+ generation Aircraft but the problem of this stealth aircrafts are its maintenance, the cost of maintenance is very high , and another major limitation of this stealth aircrafts is firepower . Stealth aircraft carrying missiles in its internal Weapon bay limits it's firepower.
For usual patrolling and reconnaissance we can't use stealth aircrafts reason is, high cost per sortie and frequent patrolling in border areas may reveal it's RCS figure's. For such missions we need aircrafts like ORCA with advanced sensors.
Another important thing is we can export these aircrafts and can earn money, strategic partnerships and crucial influence over friendly countries . Influence is one of the next generation Weapon which China already mastered and outperformed all other countries.
So in short it will be nice if we a develop a ORCA and TEDBF for our forces to replace old fighters of IAF, to get some revenue and to counter the extreme threat from China-Pak Nexus.
The lack of vision in Defence sector turned out into costly for India in the past it's the Time to act with vision.
