Osa class missile boat
Encyclopedia
The Project 205 Tsunami, more commonly known by their NATO reporting name
Osa, are a class of missile boats developed for the Soviet Navy
in the early 1960s. The Osas are probably the most numerous class of missile boats ever built, with over 400 vessels constructed for both the Soviet Navy and for export to allied countries. "Osa" means "wasp" in Russian, but it is not an official name. The boats were designated as "large missile cutter
s" in the Soviet Navy.
), their endurance, sea keeping, and habitability were modest at best, and the missile box was vulnerable to damage from waves. Among their other weak points were the wooden hull, the radar set lacking a fire control unit, and an inadequate defensive armament consisting of two manually operated 25 mm guns with only a simple optical sight in a single turret. The Komars' offensive weapons were a pair of P-15 Termit
(NATO: SS-N-2 "Styx") missiles, and there insufficient capacity to hold the more recent longer-ranged P-15Ms. The sensors were not effective enough to use the maximum range of the missiles, and the crew of 17 was not large enough to employ all the systems efficiently.
As a result of these well recognized shortcomings, Komars were organized in squadrons of six units, because it was expected that every NATO destroyer
needed two missile hits to be sunk and this could only be assured with 12 missiles. Since Komars were rated with a rather low survivability, it was necessary to use three squadrons for every target to ensure success. In order to remedy all these shortcomings, it was felt that bigger boats were needed to mount the necessary equipment and to provide more space for a larger crew.
The hull was made of steel, with a low and wide superstructure made of lighter AMG alloys, continuous deck, and a high free-board. The edges of the deck were rounded and smooth to ease washing off radioactive contamination in case of nuclear war. The hull was quite wide, but the Project 205 boats could still achieve high speeds as they had three Zvezda M503 radial diesel engines capable of a combined 12,000 hp (15,000 hp on Project 205U onward) driving three shafts. The powerful engines allowed a maximum speed of about 40 knots (with 60 hp/ton, three times that of a 'fast tank' like Leopard 1) together with reasonable endurance and reliability. There were also three diesel generators. Two main engines and one generator were placed in the forward engine room, the third main engine and two generators in the aft engine room. There was a control compartment between the two engine rooms.
The problem related to the weak anti-aircraft weaponry of the earlier Project 183R was partially solved with the use of two AK-230
turrets, in the fore and aft deck. An MR-104 Rys (NATO: "Drum Tilt") fire-control radar was placed in a high platform, and controlled the whole horizon, despite the superstructures that were quite wide but low. Even if placed in the aft, this radar had a good field of view all around. The AK-230 turrets were unmanned, each armed with two 30 mm guns capable of firing 2,000 rpm (400 practical) with a 2,500 m practical range. Use against surface targets was possible, but as with the previous Komar ships, once all missiles were expended it was planned to escape and not fight. Truly effective anti-surface weaponry was not available until the introduction of the Project 12341.1 Molniya (NATO: "Tarantul
") class corvettes, with 76 mm guns.
The missile armament consisted of four box-shaped launchers (protected from bad weather conditions) each with one P-15 Termit
(NATO: SS-N-2 "Styx") missile. This doubled the available weapons compared to the Project 183R, giving greater endurance. The missiles were controlled by a MR-331 Rangout (NATO: "Square Tie") radar and a Nikhrom-RRM ESM

that even allowed targeting over the horizon, if the target's radar was turned on.
With all these improvements, these ships were considerably more effective. They had one of the first, if not the first close-in weapon system
s (CIWS). The survivability rating was improved to 50%, and the required volley of 12 missiles could be launched by only three ships. Sinking a destroyer was therefore regarded as 'assured' using only six ships (two squadrons of three vessels), making the Project 205 vessels easier to coordinate and even cheaper than would be the required number of Project 183R boats to achieve the same effectiveness.
As a result of these improvements, Project 205 boats were without equal in the late 1950/early 1960s. Over 400 were made in USSR, and another 120 in China. Some of the improved Project 205U (Osa II) were equipped with the 9K32 Strela-2 (NATO: SA-N-5 "Grail") surface-to-air missile
s in MTU-4 quadruple launchers, in an attempt to improve air-defences. This new model also had improved, more powerful engines, and new cylindrical missile boxes, with the improved P-15U missiles. The later 205M and 205mod boats had longer tubes for the further-improved P-15M missiles.
In addition to the above, the Project 206 family of fast attack craft (NATO: Shershen
, Turya
, and Matka
class) are based on the Project 205 and share a common engine room design.
, and Indo-Pakistani War of 1971
. The Israelis sank an Osa class Syrian boat during the Battle of Latakia
, while the Indian Navy, in contrast, was quite successful against the Pakistani Navy in its Operation Trident (Indo-Pakistani War)
. Osas were also used in the Iraq-Iran War, with many losses, especially in a single battle in 1980 when several were destroyed by F-4
s with AGM-65
s. This battle occurred on 29 November 1980 and the Iraqi Navy incurred heavy damage.
Syrian Osa II's have been used in the 2011 Syrian Uprising
. Osa II's were filmed firing their deck guns into the city of Latakia.
The shortcomings that the Osas had were mainly the low efficiency of their missiles against small and ECM-equipped targets, as seen in 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, 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 armed with only four P-15s. They finally had a better electronic suite and a 76 mm gun with high rate of fire. CIWS and 'Bass Tilt' radar were fitted, and at one time they were equipped with Moskit supersonic missiles. Few were built, however, and so the Osas, after replacing the old Komars, remained widely in service, until recent years.

The Project 205 boats are bigger than the pioneering Project 183R (NATO: Komar class) boats, with a mass four times greater, and nearly double the crew. They were still meant to be 'minimal' ships for the planned tasks.The hull was made of steel, with a low and wide superstructure made of lighter AMG alloys, continuous deck, and a high free-board. The edges of the deck were rounded and smooth to ease washing off radioactive contamination in case of nuclear war. The hull was quite wide, but the Project 205 boats could still achieve high speeds as they had three Zvezda M503 radial diesel engines capable of a combined 12,000 hp (15,000 hp on Project 205U onward) driving three shafts.
