Damn, they go crazy these days....Just look at the article and see how many sources they quote(Spoiler it's zero). This is the same news site that has also claimed that 4 Gripens can do the job of an entire squadron of J-10C. It an obvious propaganda outlet that's operated by basically one person trying to pose as a reliable and reputable defence news company. IDRW is just a forum for Indian nationalists to come together and try to dispel their all consuming inferiority complex.
I kept trying to search up about the VT-4's supposed reliability issues but all I could find are two obscure articles. In those articles, they mentioned about how Nigerian outlets reported various issues of the VT-4, including it failing to fire its main cannon during exercise.
I know I'll probably sound very stupid this time, these articles are probably fake but hey, hope you guys can help verify if they are true.
