A container aboard the Victoria holding a C-704 "Nasr"
The IDF has released an inventory of weapons found on the Victoria:
230 mortar shells, 120 mm
2,270 mortar shells, 60 mm
6 C-704 anti-ship missiles
2 radar systems manufactured in England
2 hydraulic mounting cranes for radar system
66,960 bullets for the Kalashnikov, 7.62 millimeter
It's an interesting selection of arms. Had the AShM delivery been successful, it would have provided quite a surprise. It's not certain they would have solely been used in the ASh role either, perhaps offering a more variable missile strike capability for Gaza defense forces. Mortar ordnance, also, is in demand given the immense tactical strengths of the IDF and the relatively puny resources of the Gaza defense forces.
Given the successful deployment of somewhat larger Iranian AShMs during the 33-Day war, we're left to speculate on the effectiveness of a C-704 in the Gaza theater, particularly had its successful deployment possessed the element of surprise. It's relative size would have better facilitated delivery through the current blockade and provided Gaza defense forces with a considerably more potent strike capability; this force which has had to make due with the meager resources of crude, homemade rocket artillery types of negligible tactical value.
