The DOJ press release linked elsewhere in the thread says at least one employee was jailed: "Second, from in or about 2002 through September 2015, Dennis Balius, the SPI testing lab supervisor, led a scheme to alter tests within SPI’s computerized systems and provide false certifications with the altered results to customers. Balius also instructed employees to violate other testing standards, such as increasing the speed of the testing machines or cutting samples in a manner that did not meet the required specifications. Balius pleaded guilty in July 2017 and was sentenced to three years in prison and ordered to pay over $170,000 in restitution." The penalty is only $46 million because they've yet to be able to determine (like in court) that the claimed loses (like the failed launches) were actually a consequence of SPI's fraud. The damages are likely on the scale of the orders actually made.
