The first two launches took place Wednesday; the last two were on Friday. All occurred before sunrise.
The tests are part of a program to extend the strategic weapons system’s lifespan into the 2040s.
“Our nation’s sea-based deterrent has been a critical component of our national security since the 1960s, and this week’s launches continue to demonstrate the credibility and reliability of our life-extended missiles,” said Vice Adm. Johnny R. Wolfe, director of the the command responsible for the Navy’s strategic weapons.
The 45-foot-long Trident II missiles have a range of 4,000 nautical miles and carry either eight or 14 independently targetable thermonuclear warheads.
They are deployed on 14 Ohio-class submarines, each of which had 24 of the weapons. The submarines are nicknamed “boomers” because of their missiles’ destructive power.
The Navy said the launches this week marked 176 successful flights of the Trident II weapon system.
