18 f-16 blk52 vs 240 MKI??
You forgot to mention, Some of these 240 is also target on China. Let's divide it.
70+ F-16 Block 40/50 are more capable than enough to defend our sky, we are doing well to update high standards.
Meanwhile, India's Su-30MKI has some serious engines problems, read article below
India’s New Fighters Have Serious Engine Problems — War Is Boring — Medium
"In March, Indian defense minister Manohar Parrikar revealed the propulsion problems.
There have been no fewer than 69 investigations involving engine failures since 2012, according to Parrikar. Between January 2013 and December 2014 alone, the Indian Air Force recorded 35 technical problems with the turbofans.
Parrikar attributed the failures to faulty bearings that contaminated the plane’s oil supply. It seems that metal fatigue led to tiny pieces of metal shearing off the friction-reducing bearings, which then entered the oil system.
This accounted for 33 of 69 engine failures.
Another 11 failures were the result of engine vibrations, while eight more arose from a lack of pressure in that same lubricating oil. New Delhi has not revealed the cause for the remaining 17 incidents.
The Air Force responded by taking the issue up with NPO Saturn, the Russian manufacturer. According to Parrikar, the company has come up with nine different modifications to help solve the problems.
India has already incorporated these “fixes” into 25 engines built at its plant in Koraput. In the future, the engines should benefit from an improved lubrication system, superior-quality oil and bearings that are a better fit.
However, a more general worry for the Air Force is the poor serviceability of the Su-30MKI fleet — meaning the number of aircraft actually available for operations on a daily basis.
Based on figures given by Parrikar, only 110 Su-30MKIs are “operationally available.” From a total of more than 200 aircraft that Irkut and HAL had delivered by February 2015, that means 56 percent are ready at any given time.
