The CIWS is a 30mm also, more firepower than the US CIWS.
I just remember when the US PT boats were out it was the most firepower in the smallest ship pound for pound. I wonder what ship holds that title now? That Veer has to be in the running.
The Veer's double CIWS is grand-looking and impressed me too, but loses out to the more modern Kashtan system IMHO.
The Veer would probably give the Greek Roussen class and Egyptian Ezzat class a run for their money, but IMHO the king of the small missile boat category goes to the Israeli Sa'ar-4.5 class, example INS Tarshish below.
The Sa'ar 4.5 carries a 76mm gun, Phalanx CIWS, 16 Barak-1 SAMs, 8 Harpoon AShM and sometimes ASW torpedo tubes too, but I vote her mainly because of her dazzling array of ECM systems, possibly the most on any ship of any size currently in service. A matter of quality over quantity...
...but if raw throw weight is what one desires, the Taiwanese Tuo Chiang class is no slouch either with 16 antiship missiles and a very intriguing structure to boot.
