According to the information of the Internet portal flotprom.ru, Almaz Central marine design Bureau announced a new export offer – small missile ship (small Corvette) 22800Э project "Karakurt" with the Italian 76-mm gun OTO Melara, MTU diesel engines and electronic weapons Thales. The domestic version of the project 22800При buyers can opt for a modification with Russian engines, gun mounts and radar. The developer believes that the version with foreign components may largely be of interest to customers. In the first place are due to the Indian Navy, as the country, carrying out active re-equipment of the troops, seeks to maximize diversification in the field of armaments and military equipment.

76-mm gun mount OTO Melara "Italian" export variant "the black widow" is proposed to equip the 76-mm gun mount OTO Melara.

March 2, 2017 the St. Petersburg engineering plant "Arsenal" announced the successful testing of the AK-176МА.Another creation of the Italian company: Oto Melara Davide/Strales guided projectile with DARTКак the source indicated in the ikbb, with the installation of the Italian guns will require the creation of new weapons systems and fire control of the ship.According to captain first rank, doctor of Sciences Konstantin Sivkova, the decisive advantage is on the side of the AK-176МА:the Issue in rate of fire, because the main threat to IRAS is a means of air attack: cruise missiles and aircraft.

Artduel the sea is now unlikely. This gun will solve the problem of air defense on the distant approaches – 10-12 km. To the fore here come the integration into the unified air defense system of the ship and the rate of fire.In his words, AK-176МА better corresponds to the "Karakurt", especially when defending the ship against air targets. Coupled with the AK-630 and the guidance systems of weapons forms a closed air defense system, effectively working within his race of fire.
