The Nanuchka I class was a series of missile corvettes built for the Soviet Navy and export customers between 1969 and
1981. These ships were designed around the SS-N-9 antiship missile, while export versions used the SS-N-2 of inferior
prestations. The SS-N-9 has a range of 150 nautical miles and it requires mid-course guidance to strike targets "beyond
the horizon". These ships served as complement of the antisubmarine corvettes of the classes Grisha I and Grisha II,
being an adequate mobile defense of the Soviet/Russian coasts until their retirement in the 1990s.
These ships took into account the lessons learned in occassion of the Arab-Israeli conflict of 1973. It was required a
larger ship equipped with electronic devices of higher quality and more sophisticated missiles. With a much larger hull
than the patrol boats of the Osa class, they carried not only a much more effective missile but also artillery armament.
The larger hull should allow to operate in rougher waters and the wide beam would allow for a stable firing platform.
In the illustration the SA-N-4 pop-up launcher is not visible, being hidden on its "silo" at prow.
