BB begs to differ , technologies just don't evolve , one needs to have sufficient industrial base , experimental capital , required skills & research and development. It take years to develop these bits of technologies.
It took Kumitsu 20 years of research before they came up with a semi autonomous Truck ! - the point i am trying to get across is that developing the technologies i have listed are a little bit more complicated than making chicken biryani or making mango lassi for lunch.
India has no such expertise and i am not saying that they cant develop them but it will take way tooo long time and the project will become another LCA.
India would have to take help from other countries which will make this "indigenous " UCAV "Non Indigenous".
