The survivability of CVN 78 in a cyber-contested environment has not yet been evaluated. Many subsystems on the ship were tested to various degrees in both developmental testing and operational testing on other ship platforms. However, required CVN 78 platform-level testing has not yet occurred, ...
Due to this incident, then-President Ronald Reagan instituted the “Zero Tolerance” policy across all of the armed services – which started the mandatory drug testing of all US servicemen and women. In the Gulf of Sidra incident (1981), while conducting a freedom of navigation exercise in ...
The resulting capability is placed in perspective with the state-of-the-art crack initiation methodology based on the slow bend testing of recracked specimens, presently under standardization world-wide. The investigation leads to highlight three conceptual weaknesses of current enfgineering and ...
Affinity Lifestyles, the now defunct company that manufactured Real Water, conceded liability for the plaintiffs injuries but maintains they shouldn’t be responsible for punitive damages, because the supposed industry-standard testing they used wasn’t calibrated to detect hydrazine. Three previ...
The ship is in the early stages of its testing program and is on schedule to launch during the fourth quarter. The christening is planned for late 2019. The upper bow unit of the nuclear-powered aircraft carrier John F. Kennedy (CVN 79) is the last superlift that completes the primary st...
