The Kuznetsov NK-32 is an afterburning three-spool low bypass turbofan jet engine which powers the Tupolev Tu-160 supersonic bomber, and was fitted to the later model Tupolev Tu-144LL supersonic transport. It produces {{convert|245|kN|abbr=on}} of thrust in afterburner.

A non-afterburning variant known as NK-32 Tier 2 for Tu-160 and NK-65 will be used in the upcoming Russian bomber, PAK DA.{{cite web|url=https://www.ruaviation.com/news/2014/8/19/2551/?h|title=An engine for PAK DA bomber will be derived from the engine, which powers Tu-160 - News - Russian Aviation - RUAVIATION.COM|author=|date=|website=www.ruaviation.com|accessdate=13 January 2019}}

NK-65 and a geared high-bypass turbofan variant PD-30, with a thrust of {{convert|30000|kgf|kN lbf}} has been proposed for use on new Russian wide-body airliners, as well as the upgraded Antonov An-124 Ruslan heavylifter.{{cite web|title=PD-30: future Russian thirty-tonner|url=http://www.en.take-off.ru/news/107-june2012/728-pd30futurerussianthirtytonner|publisher=Take-off magazine|accessdate=7 March 2016|archive-url=https://web.archive.org/web/20160308012217/http://www.en.take-off.ru/news/107-june2012/728-pd30futurerussianthirtytonner|archive-date=8 March 2016|url-status=dead}}{{cite web|url=http://fantasylab.ru/take-off-en/news/107-june2012/728-pd30futurerussianthirtytonner|title=Take-off Magazine : PD-30: future Russian thirty-tonner|author=|date=|website=fantasylab.ru|accessdate=13 January 2019|archive-date=13 January 2019|archive-url=https://web.archive.org/web/20190113232359/http://fantasylab.ru/take-off-en/news/107-june2012/728-pd30futurerussianthirtytonner|url-status=dead}}
