My friend, Su-37 will not become operational. Due to the fact that it is a test platform for new avionics and AL-41F engine. Development of the Su-27 families are coming to an end as Russia diverts more and more funds into PAK FA program in a joint venture with India.ajay_ijn said:What is the present status of Su-35 and Su-37.
I don't think RusAF has inducted this plane,they wanted the better Su-37.
Everywhere I read about Su-37,it is given that it is undergoing flight tests from 1999.
Still is it undergoing flight tests?
Hope that helps!
