All assembled engines for Proton rockets proved to be defective


Now the Voronezh Mechanical Plant needs to go through all 71 units designed and built for Proton-M rockets, which will take a long time.

“Speaking of the Protons: these are 71 engines we’re talking about. This is almost the entire supply of the second and third stages that were produced,” said the CEO of NPO Energomash Igor Arbuzov in his interview to RIA Novosti.

Arbuzov added that big chunk of this work will be done this year, but some of it will go over to the next year.

“The main goal is to keep up with the schedule of launches for the Federal Space Program, launches for the Russian Defense Ministry, and commercial launches. Regarding the engines for the Soyuz, we need to ensure the necessary reserve in order to follow the schedule for the delivery of new crews and cargo to the International Space Station,” said the head of Energomash.

Earlier it was reported that engines RD-0210/0211 and RD-0213/0214 have been recalled. It became known that the solder that was used during their production did not comply with technical documentation.
