The class has a low radar cross-section; an integrated power system that can send electricity to the electric drive motors or weapons, the Total Ship Computing Environment Infrastructure ( TSCEI ), automated fire-fighting systems, automated piping rupture isolation, and may someday include a railgun or free-electron lasers.

Mine safety received considerable publicity in 2007, particularly after 3, 200 workers were temporarily trapped underground at the Elandskraal mine after a compressed air pipe ruptured due to internal corrosion, broke lose and fell into the man-hoisting shaft .

The emergency cooling systems that are meant to protect nuclear reactors from melting down in case a water pipe ruptures could fail after a few minutes of use at most reactors, according to a nuclear watchdog group that is citing a government study to argue that the problem makes a catastrophe at one power plant in New York 100 times more likely.

A similar situation occurred during the Chernobyl disaster : after the reactor was destroyed and began to burn, a liquid corium mass from the melting core began to breach the concrete floor of the reactor vessel, which was situated above the bubbler pool ( a large water reservoir for emergency pumps, also designed to safely contain steam pipe ruptures ).
