guns into the city of Latakia. The shortcomings that the export Osas had were mainly the low efficiency of their missiles against small and ECM-equipped targets, as seen in the Battle of Latakia. In this conflict, Osas and Komars fired first, thanks to the longer range of missiles and favourable radar propagation conditions, but missed the targets due to jamming, and were not capable of escaping due to some engine malfunctions. The lack of medium caliber gun hampered defence against gunboats, even though the USSR had 37, 45 and 57 mm guns capable of being fitted in place of one 30 mm gun, as happened in some other vessels, such as the Poti ASW corvettes. Effective anti-missile systems were never equipped even though there was no significant size or weight difference between the AK-230 and the AK-630 CIWS. The successor was the Project 1241 Tarantul class corvette, with twice the displacement and a higher cost, but still initially armed with only four P-15s. They finally had a better electronic suite and a 76 mm gun with high rate of fire, along with newer P-270 Moskit and Kh-35 supersonic missiles, AK-630 CIWS, and 'Bass Tilt' radars. Fewer were built however, and so the Osas, after replacing the old Komars, remained widely in service up to the turn of the 21st century. Operators About 175 Osa I and 114 Osa II boats were built for the Soviet Navy, the last were decommissioned in about 1990 in the main Soviet fleet. Amongst the post-Soviet countries, one boat is in service with the Azerbaijan Navy and two are in service with the Latvian Navy. Osa I Military of Benin – 2 boats in 1979 Bangladesh Navy – 5 boats People's Liberation Army Navy – 4 boats in early 1960s plus over 130 license-produced. Egyptian Navy – 3 boats (plus two in reserve) remain from 13 transferred from the Soviet Union in 1966–68, some of which were sunk during the Yom Kippur War in 1973. The survivors were re-engined in 1994 and given Litton Triton radar intercept systems. 5 ex-Yugoslav boats were bought in 2004 for less than $1m a piece, refitted in Montenegro and delivered in 2007. East German Navy – 15 boats transferred 1962–1971 – decommissioned 1981–1990 Indian Navy – 9 boats transferred 1968-1971. Known as Vidyut-class missile boats. Decommissioned 1983–1997. Latvian Navy – 6 ex-East German boats, decommissioned during the 1990s. North
