So the predecessor was involved in 4 consecutive mishaps and the successor never even used? Not sure who is mistaking here.

- avmich 12y agoThe reason NK-15 were exploding was traced back to turbopumps. Those were completely redesigned, from scratch, for NK-33. That alone justifies a new name for the engine. Then, unlike NK-15, NK-33 are multi-start engines. Were tested for ridiculously long work times - one worked non-stop for ~14000 (fourteen thousands) seconds on a stand.
