This article https://news.yahoo.com/did-russia-us-sneak-peak-200000856.html mentions Russia's proposed Laika/Husky project which was meant to be smaller and cheaper than the Yasens and slowly replace the Yasens.
This article https://news.yahoo.com/did-russia-us-sneak-peak-200000856.html also indicates Laika/Husky "will reportedly displace 11,340 metric tons" and perhaps start building in "2023".
https://news.yahoo.com/did-russia-us-sneak-peak-200000856.html seems oblivious to the fact that according to https://en.wikipedia.org/wiki/Yasen-class_submarine#Units 8 Yasens (of 8 to 14,000 ton size) are at various stages of launching, trialling and some building with commissioning of the last into the late 2020s if not later.
According to https://en.wikipedia.org/wiki/Laika-class_submarine#History it will be only in 2027-2030 that the first Laika/Husky will be "built". So full trialling/commissioning of this first Laika/Husky may extend into the mid-2030s.

Hi Pete
According to Director General of Malakhit Marine Engineering Bureau, stealth is emphasized for Russian fifth generation multipurpose submarine, Laika/Husky, and is achieved by structural consideration. Detection of submarine is carried out by monitoring heat, magnetism and sound/vibration. As magnetism depends on material (hull, etc.), reduction of footprint of sound/vibration may be carried out by stealth oriented submarine shape including mast and hull. Diamond shape is adopted to Type212CD to reduce the footprint [2,3], and this concept may be adopted Laika/Husky.

"There is one significant point - the information integration of submarines with surface and air forces contradicts the idea of a submarine as a" hidden vessel ", since the fact of information exchange is unmasking. But this is an area that needs serious scientific and technical groundwork," Dorofeev (Director General of Malakhit St. Petersburg Marine Engineering Bureau) noted.
“Today they require an adequate response to detect submarines. It is possible that there will be structural solutions that protect boats from being detected by those physical fields that were not previously considered basic,” Dorofeev said in an interview with RIA Novosti.
