GROTON, Conn. — The Navy officially brought its newest attack submarine into service Saturday, commissioning the USS Idaho at Naval Submarine Base New London.
It was the usual pageantry—flags, speeches, brass—but underneath it all was the real story: another nuclear-powered hunter slipping quietly into the fleet at a time when undersea dominance matters more than ever.
The USS Idaho is the 26th boat in the Virginia-class and part of the more refined Block IV design—built to stay out longer, deploy more often, and spend less time tied up in maintenance. In plain terms: more time on station, less time in the yard.
Cmdr. Chad J. Guillerault, the boat’s skipper, leaned into the heritage angle—but also hinted at the job ahead.
“The Idaho connection is more than a name… it is a legacy being reborn today, he said.”
The numbers tell you what kind of machine he’s taking to sea:
- 377 feet long
- 7,800 tons submerged
- Nuclear reactor that won’t need refueling for its entire service life
That last point matters. No refueling means fewer long overhauls and more operational time—exactly what the Navy needs as demand for submarines keeps climbing while shipyard capacity struggles to keep up.
The Idaho was christened in March 2024 in Groton, and now it joins a force that’s stretched thin but still carries the quiet edge of American naval power.
No fanfare once it leaves port. No headlines when it’s on patrol.
That’s the point.
