Question: What was the Soviet designation for the class of destroyer that is complemented by the Udaloy-class destroyer?

full_context: Document 1: Sarov-class submarine: The Sarov class is a submarine class built by Russia. There is a single boat of the class, the "Sarov" itself. It serves to test and develop new technologies and new weaponry for the Russian Navy. It was first revealed publicly when details of the boat were published by accident on the Sarov, Nizhny Novgorod region's local government website as part of an account of a meeting with its commander. The number of the submarine project was given as 20120 and some technical and tactical characteristics were revealed as well.
Document 2: Leninets-class submarine: The Leninets or L class were the second class of submarines to be built for the Soviet Navy. They were minelaying submarines and were based on the British L-class submarine, HMS "L55" , which was sunk during the British intervention in the Russian Civil War. Some experience from the previous "Dekabrist"-class submarine s was also utilised. The boats were of the saddle tank type and mines were carried in two stern galleries as pioneered on the pre-war "Krab" , the world's first minelaying submarine. These boats were considered successful by the Soviets and 25 were built in four groups between 1931 and 1941. Groups 3 and 4 had more powerful engines and higher speed.
Document 3: Neustrashimy-class destroyer: Neustrashimy (Неустрашимый, Dauntless) was a destroyer built for the Soviet Navy in the early 1950s. She was to be the prototype for an extended production run but only one ship was built. "Neustrashimy" was considered too big for series production and a modified design, the Kotlin class was chosen for series production instead. The Soviet Designation was "Project 41". This was the first Soviet ship to be given a NATO reporting name being called the "Tallinn" class.
Document 4: Riga-class frigate: The Riga class was the NATO reporting name for class of frigates built for the Soviet Navy in the 1950s. The Soviet designation for these ships was "Storozhevoi Korabl" (escort ship) "Project 50 Gornostay" ("Ermine stoat"). The Riga class was analogous to World War II era destroyer escorts.
Document 5: Russian submarine Bryansk (K-117): K-117 "Bryansk" is a Russian Project 667BDRM Delfin class (NATO reporting name: Delta IV) nuclear-powered ballistic missile submarine. The submarine was laid down in April 1985 in the Russian Northern Machinebuilding Enterprise, Sevmash. In September 1988 the submarine was commissioned in the Soviet navy. When launched the submarine became the 1000th Russian/Soviet submarine constructed. After the collapse of the Soviet Union the submarine continued to serve in the Russian navy. In July 2002 the submarine went into overhaul and didn't return until early 2008. As of 2010 the submarine is on active duty with the Russian Northern Fleet.
Document 6: Mod Kashin-class destroyer: The Modified Kashin class were six ships built and modified based on the Kashin class destroyer for the Soviet Navy between 1973 and 1980. Seven more ships were built after that for the Indian Navy. The Soviet designation for the Mod Kashin is "Project 61MP".
Document 7: Sovremennyy-class destroyer: The "Sovremenny"-class destroyer is the principal anti-surface warship of the Russian Navy ("Sovremenny" translates like "Modern"). The Soviet designation for the class was Project 956 "Sarych" (Buzzard).
Document 8: Juliett-class submarine: The Project 651, known in the West by its NATO reporting name Juliett class, was a class of Soviet diesel-electric submarines armed with cruise missiles. They were designed in the late 1950s to provide the Soviet Navy with a nuclear strike capability against targets along the east coast of the United States and enemy combatants (aircraft carriers). The head of the design team was Abram Samuilovich Kassatsier. They carried four nuclear-capable cruise missiles with a range of approximately 300 miles, which could be launched while the submarine was surfaced and moving less than four knots (7 km/h). Once surfaced, the first missile could be launched in about five minutes; subsequent missiles would follow within about ten seconds each. Initially, the missiles were the inertially-guided P-5 (NATO reporting name SS-N-3c Shaddock). When submarine-launched ballistic missiles rendered the P-5s obsolescent, they were replaced with the P-6 (also NATO reporting name SS-N-3a Shaddock, though a very different missile) designed to attack aircraft carriers. A special 10 m target guidance radar was built into the forward edge of the sail structure, which opened by rotating. One boat was eventually fitted with the Kasatka satellite downlink for targeting information to support P-500 4K-80 "Bazalt" (SS-N-12 Sandbox) anti-ship cruise missiles.
Document 9: Udaloy-class destroyer: The Udaloy I" class are a series of anti-submarine destroyers built for the Soviet Navy, eight of which are currently in service with the Russian Navy. The Russian designation is "Project 1155 Fregat". Twelve ships were built between 1980 and 1991, while a thirteenth ship built to a modified design as the Udaloy II" class followed in 1999. They complement the Sovremennyy-class destroyer in anti-aircraft warfare and anti-surface warfare operations.
Document 10: Kashin-class destroyer: The Kashin-class destroyers were a group of guided missile destroyers built for the Soviet Navy in the 1960s and early 1970s. Their Soviet designation was Project 61. s of 2016 , one ship is in service with the Russian Navy, and five modified ships are in service with the Indian Navy as "Rajput"-class destroyer s.
Document 11: Kildin-class destroyer: The Kildin-class destroyer was a series of destroyers built for the Soviet Navy in the late 1950s. They were a missile armed version of the Kotlin-class destroyer , and the class was named for Kildin Island. Four ships were built around the KSShch (КСЩ, SS-N-1) anti-ship missile. When this missile became obsolete in the 1960s, three ships were modernised in 1972-1977. All ships were decommissioned in the late 1980s early 1990s. The Soviet designation was Project 56EM for the prototype ("Bedovyy"), Project 56M for three series ships, and Project 56U for the modernised ships.
Document 12: Kola-class frigate: The Kola class was the NATO reporting name for a group of frigates built for the Soviet Navy in the 1950s. The Soviet designation was "Storozhevoi Korabl" (escort ship) Project 42. These ships were analogous to World War II era destroyer escorts or German Elbing-class torpedo boat s. The programme consisted of only 8 ships as these vessels were considered to be too expensive for series production and the smaller and cheaper Riga-class frigate was built instead. Radars and sonars were fitted.
Document 13: Maria Yermolova-class passenger ship: The passenger ships of this project were made from 1974 to 1978, under a colossal provincial shipyard contract USSR signed by order of Leonid Brezhnev at the personal request of Marshal Tito for the salvation of the Yugoslav shipyard. Eight ice-class vessels of project 1454 were built, the only of their kind in the world. Three vessels were delivered to Murmansk Shipping Company (MMP), four to Far East Shipping Company (FESCO), and one vessel to the Sakhalin Shipping Company - NSR Kholmsk. The vessels were built in two series. The first series consisted of: "Maria Yermolova", "Maria Savina", "Alla Tarasova" and "MV Lyubov Orlova". The second series was: "Olga Androvskaya", "Olga Sadovskaya", "Claudia Elanskaya" and the "Antonina Nezhdanoff". The vessels were used as cruise ships for Soviet and foreign tourists.
Document 14: Gnevny-class destroyer: The "Gnevny" class were a group of destroyers built for the Soviet Navy in the late 1930s – early 1940s. They are sometimes known as the "Gremyashchiy"-class destroyer and the Official Soviet Designation was "Project 7". These ships fought in World War II.
Document 15: Los Angeles-class submarine: The "Los Angeles" class is a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy. The submarines are also known as the 688 class, after the hull number of lead vessel  . They represent two generations and close to half a century of the U.S. Navy's attack submarine fleet. As of 2017, 36 of the class are still in commission and 26 retired from service. Of the 26 retired boats, 14 of them were laid up half way (approximately 17–18 years) through their projected lifespans due to their midlife reactor refuelings being cancelled. A further four boats were proposed by the Navy, but later cancelled. The class has more operating nuclear submarines than any other in the world. All submarines of this class are named after American towns and cities (e.g., Key West, Florida, and Greeneville, Tennessee), the exception being USS "Hyman G. Rickover" . This system of naming broke a long-standing tradition in the U.S. Navy of naming attack submarines for creatures of the ocean (e.g., USS "Nautilus" ).
