In brief
Sovetskiy Soyuz (Russian: Советский Союз, IPA: [sɐˈvʲetskʲɪj sɐˈjus] ; literally: Soviet Union) was the fourth Russian Arktika-class nuclear-powered icebreaker operated by FSUE Atomflot. The ship, which is named after the Soviet Union, was built by Baltic Shipyard in Leningrad and entered service in 1990. She was decommissioned in 2014.
In January 2016, it was reported that the icebreaker will be converted into a command ship. However, this was later retracted and the nuclear-powered icebreaker is now slated for scrapping.

In context
Every figure in this section is a count, a rank or a percentile over vessels actually held in this registry — not over the world fleet, which is larger. Nothing here is estimated.
At 20,646 gross tons, Sovetskiy Soyuz is the 26,265th largest of the 84,014 vessels in this registry that report a tonnage. The median across that set is 5,994 GT, so this hull is about 3.4 times the typical vessel on record here. The largest measures 499,167 GT.
Among the 612 research / surveys held here, it ranks 11th by tonnage — larger than 98% of that group. Their median tonnage is 2,180 GT, and the largest tenth begin at 9,452 GT. The flag most often flown by this group is United States (90 ships). The yard that appears most often against it is Wärtsilä, with 36 hulls on record.
Russia is the country of registry for 2,810 vessels in this directory, of which Sovetskiy Soyuz is the 50th largest by tonnage. The most common class under that flag is vessels this registry holds no type classification for (830 ships), and the median vessel measures 2,293 GT. Browse every ship flagged Russia.
Narrowing to both dimensions at once, this registry holds 69 research / surveys flying the Russia flag, of which 9 are larger by tonnage.
Sovetskiy Soyuz was built in 1989, making it 37 years old. It is one of 1,131 hulls in this registry delivered that year, a cohort whose median tonnage is 1,938 GT; within it this ship is the 183rd largest. Across the whole of the 1980s the registry holds 13,213 vessels, median 3,004 GT. The median build year across the entire registry is 1995.
The registry attributes 43 vessels to Baltic Shipyard, with a median tonnage of 20,646 GT, delivered between 1960 and 2022. See the rest of that yard’s output.
At 147.9 m overall, Sovetskiy Soyuz is 76.9 m longer than the 71.0 m median for research / surveys on record, with a beam of 30.0 m and a draft of 11.0 m.
IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8838582 this registry holds 18 other vessels, whose median build year is 1988 and which range from 1981 to 1991. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1989.
Its IMO number, 8838582, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 8×6 + 3×5 + 8×4 + 5×3 + 8×2 = 182 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
