Karan, I had tried to get confirmation on this from the Tejas LCA FB page many months ago, but not received any reply as yet.
The problem is that some of these articles (like this one
) seem to interchangably use the term i-Derby, whereas the suffix 'i' was for the upgraded variant and not the older Derby that the Indian Navy bought and whose stocks were transferred over to the IAF with the Sea Harrier retirement. So its not clear whether the Tejas integration that some of these articles referred to was with the older Derby or the new i-Derby-ER. My guess is it was actually the older Derby missile.
While the connectors, pylon adaptors, the overall missile dimensions, shape and possibly even weight could be the same, the mass distribution may change on the new i-Derby ER missile compared to the Derby thanks to the modified location and size of the proximity fuse and dual pulse motor. Might possibly require some more work to be done versus just replacing the Derby? I don't know, you're the expert here.
Aviation Week explicitly stated that the integration work for the i-Derby ER and not the Derby is in work.
Unlike the AAIM-120D or Meteor, I-Derby ER will be compatible with aircraft currently cleared to carry Derby. RAFAEL claims it will be able to deliver 80% of the Meteor’s performance at a third of its cost. It is also superior to the AIM-120C7 and more affordable, the company claims. Already cleared on F-16 (Block 52), F-5E, Kfir and Sea Harrier, I-Derby ER integration tests are currently under way on the Indian Tejas LCA.
