I dont know what to say, its only till AMCA is ready. F-15 is a better choice, even in small numbers. The reason was a far choice even The DM was seen in the cockpit. So why would they when Dassault is seen as the perfect choice. We are friends with the US so it is looking better in a hypothetical scenario. Can you tell me what made sense according to you other then what you have written? I am new to this defence forum and dont have much to say, it will help me. Please dont take it as if I am mocking you.
Old F 15 and their upgrade maintenance is a very costly affair nor do they provide us any advantage which we don't have with Flankers which will be upgraded soon.
A new plane isn't just some samosa you can buy from anywhere in Delhi and mix it with chutney to have the perfect evening snack. Training maintenance spare parts supply guarantee engines these thing are also part of deal. So neither they will be cheap nor bringing anything new.
IAF require numbers not a circus of umpteen no. Of platforms in small no. with USA having the string to take them down when they want. We already have Rafale armed with meteor and mica which gives us access to western tech.
By the time we will be done with getting familiar with F 15 they will be outdated as well as AMCA will be in advance stage of induction..
Your suggestion is akhand chutiyapa sorry but that is what it is. Don't mind bro but the only aircraft we are inducting now is Rafale and the future is Tejas.
When you don't know what to say listen to others and learn and keep those hypothetical scenario little but sensible too. Anyway we aren't getting them so no point in wasting time over it either.
