These two seem to have been very similar apart from the former's T-tail, so I wondered whether they should be in the same article. Two reasons for keeping them apart: (i) their histories are distinct and (ii) if we ever get more details (performance etc} of the HB-4, differences may appear, so for now I did not merge them. Any info on the HB-2 and HB-3, built or not, would be helpful.TSRL (talk) 21:34, 25 May 2021 (UTC)Reply
