A small number of W76-2 low-yield warheads have also been deployed on some Ohio-class submarines. In 2009, the United States upgraded the D5 missiles with an arming, fuzing and firing (AF&F) system called the "super-fuze"[7][8] that allows them to target hardened silos and bunkers more accurately. Night vision goggles provide greater safety during night operations by increasing the pilot's ability to visually clear terrain, to increase the peacetime and combat situational awareness of the aircrew and visually acquire other aircraft. Each of the 170-meter-long vessels can carry twenty-four Trident II submarine-launched ballistic missiles (SLBMs) which can be fired from underwater to strike at targets more than seven thousand miles away depending on the load.
