a.k.a. the 30 mm/54 (1.2″) 3M87 Kortik with SA-19

another russian system that is similar in concept is 30 mm/54 (1.2″) Palash : same twin 30mm gatling as Kashtan but with different missiles and optical firecontrol ” ball” instead of Kashtan’s radar/eo fit

As an upgrade, the 30 mm/54 (1.2″) AK-630 can be fitted with 2×2 optically guided SA-19.

mount a.k.a. Oerlikon/DES 30 mm/75 DS 30B and Laurence Scott LS-30B

I’m willing to bet that mounts like the British GCM-AO3 twin Oerlikon 30mm, the German 27 mm MLG 27 Light Naval Gun System, various Italian 25/30mm or the US Mk 38 Naval 25mm chaingun could all have 2-4 MANPADS retrofitted if necessary (esp. manpads employing IRH or SACLOS guidance)
