Source-derived summary

Pyotr Lebedev is a research vessel, built at Wärtsilä Crichton-Vulcan in Turku, Finland, originally as a merchant vessel Chapayev in 1957. She was subsequently acquired for the Soviet Union and refitted as a research ship. The vessel was owned and operated by the Andreev Acoustics Institute, and was used to make hydrophysical observations of the Atlantic Ocean such as during the Polygon experiment. Pyotr Lebedev possessed five on-board laboratories used to study hydroacoustics, hydrology, hydrobiology, hydrochemistry, and electronics. The ship was active as a research vessel from 1967 until 1977. She is current registered in Saint Vincent and the Grenadines.

Editorial analysis

Why this record matters

“Pyotr Lebedev (research vessel)” is worth following because a concise public description often conceals a longer documentary argument. Here, Pyotr, Lebedev and research provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 1, 2026. The linked authority identifier is Q7263169. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1957, 1967, 1977 and 1990.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
