thought they going to purchase and operate the Hornets
The first issue would be money. The second would be the issues with supplies, pilots and logistics for an entirely foreign aircraft type.
The third would be the carrier itself ( the dimensions of elevator such like). India's future carrier will be bigger ( as big as China's carrier type 001A).
The fourth is that India has plans for its own carrier fighter jet ( twin engined like Hornets). So I seriously doubt the Hornet purchase ever going to materialize. If at all it does, it'd be only a benefit for China in a long term strategic sense as Indian industry would further struggle.
