This sounds sort of like the scare involving early Soviet nuclear subs. There was an incident where an aircraft carrier was being tracked by a Soviet sub, and the sub was able to keep up with the carrier, which was going 30+ knots. The only reason that they were able to go that fast was because the Soviet shipbuilders cut back on radiation shielding, and because of that, many of the sailors who served on such subs got cancer.

Yep. Seems like they viewed people as just another asset.
