'''LIBIS KB-11 Branko''' je bilo štirisedežno športno letalo, kovinsko-lesene konstrukcije, plod tovarne [[LIBIS]]. Izdelanih je bilo 5 letal. Letalo je bilo razvojni naslednik letala KB–6. Letalo je bilo namenjeno za turistično in poslovno uporabo.
Novost je bilo podvozje tipa tricikel,<ref>{{navedi knjigo |author=Kladnik Darinka |year=2008 |title=Zgodovina letalstva na Slovenskem: od začetkov do današnjih dni  |publisher=ZIP - Zavod za intelektualno produkcijo |isbn=978 961 91035 6 2 |cobiss=242534912 |pages=159}}</ref> ki je bilo uvlačljivo, kar je kljub povečani teži zaradi zmanjšanega upora omogočalo večje hitrosti in zmanjšano porabo goriva.
