Limiting Factor, known as Bakunawa since its sale in 2022, and designated Triton 36000/2 by its manufacturer, is a crewed deep-submergence vehicle (DSV) manufactured by Triton Submarines, built for and originally owned and operated (2018–2022) by explorer Victor Vescovo's ocean research firm, Caladan Oceanic, and currently owned and operated by Gabe Newell's Inkfish ocean-exploration research organization. It currently holds the records for the deepest crewed dives in all five oceans. Limiting Factor was commissioned by Victor Vescovo for $37 million and operated by his marine research organization, Caladan Oceanic, between 2018 and 2022. It is commercially certified by DNV for dives to full ocean depth, and is operated by a pilot, with facilities for an observer.
