Now that the truth is out about Hermes-900 not matching advertised specs, there's no justification for the Tapas program getting delayed/re-designed.
Edit: A pusher-prop config would have mitigated the Tapas' weight problems imo. But we need to adopt an iterative approach to get a decent, working UAV for all the effort invested over the years. For perspective, Nishant was in trials/limited series production in the mid-to-late 1990s when we acquired the IAI Searcher. Today, it's been retired and indigenous programs are yet to see the light of day.
