As a result, it was being self-funded by Rubin, the developer.<ref>{{Cite web |title=The Central Design Bureau "Rubin" presented to the Ministry of Defense several projects of submarines of the fifth generation |date=22 September 2021 |url=https://vpk.name/en/543537_the-central-design-bureau-rubin-presented-to-the-ministry-of-defense-several-projects-of-submarines-of-the-fifth-generation.html |access-date=2022-04-04 |agency=RIA Novosti |language=en}}</ref>
