The only official statement we have is it is a "megapixel class" captor.
But if you read carefully flight test by Vianney Riller JR, check the sentence "using spectra AND passive sensors". (talking about his passive shooting in his 6). Btw, he tested a Rafale 04T
. First delivery to operational squadron (after testings etc) due in October, a "B" version for 1/7 Sqd. Next deliveries will also be mainly B to replace 2000 N of 1/31 "Gascogne".
About signature, the very few outcomes i could have off the line were november to february.
Price? I dont have any clue. I'm only former operational...
India will get more then full version, but a customized version. Initial RFP asked for a HMS, it is now official that there will be israeli stuff in indian rafales, that negociations are on the run to integrate an ARM missile (for K!h31, but unofficially sources also talk about Harpoon). We also know that Indian Rafales will have to built from scratch as they are very different to french ones. All in all, Indian rafales wont be downgraded, but "tweaked" for IN customer.
Rumours say there will be a short self defence missile, aswell as towed decoy. But these are rumours.
About ToT, it is the big issue atm. By issue i dont mean that their is no will for ToT, but one should realize that building a Rafale is 2/3 years long, indludes hundereds thousands parts and 500 subcontrators. Each indian counterpart from the two supplying lines (which was the real story abour RElainace, securing a secind private supply chain) must be audited in order to know when they will be able to supply each part, when, on which plane, with how much help. I wish you a good night.
