Koni-class frigate
class of Soviet anti-submarine warfare frigates

The Koni class is the NATO reporting name for Project 1159 Del'fin anti-submarine warfare frigates built by the Soviet Union. 14 were built in Zelenodolsk shipyard between 1975 and 1988. They were originally intended to replace the older Riga-class frigates, but were instead chosen as a design for export to various friendly navies. The Koni I sub class were designed for European waters and the Koni II were made for warmer waters. One ship was retained by the Soviets in the Black Sea for training foreign crews. Only a few of these vessels remain in service.
The Romanian Admiral Petre Bărbuneanu-class corvettes were similar.

The Libyan vessels had a redesigned layout with the P-15M missiles forward of the bridge. The ships had contemporary Soviet radar and sonar.
This brief starts where responsible research should: with the source description of “Koni-class frigate” as class of Soviet anti-submarine warfare frigates. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as class of Soviet anti-submarine warfare frigates. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q694531. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1159, 1975 and 1988.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
