Japan’s New Mogami-Class Frigates Show What The U.S. Navy’s Littoral Combat Ships Could Have Been





The two frigates, both named after rivers, measure 132 meters long and are scheduled to be commissioned into service March 2022. They integrate a wide variety of sophisticated technologies including a high-tech command center, a stealthy hull and mast designed to reduce visibility on radar, mine-hunting aquatic drones and powerful long-range anti-ship missiles.

The Japanese Maritime Self Defense Force (JMSDF) eventually plans to procure a total of 22 of the stealth escort frigates (also designated “destroyer escorts”) built at a pace of two per year, at an estimated cost of 50 billion yen ($467 million) each. These will eventually replace eight Asagiri-class destroyers of similar weight and six smaller Abukuma-class escorts.

While the new frigates aren’t quite feature complete (more on that below), they compare well with the U.S. Navy’s infamously troubled littoral combat ships (LCS).

The FFM’s priority design features—speed, small crew size, support for unmanned vehicles, and anti-submarine and counter-mine capability—are also characteristics that guided development of LCSs. In fact, MHI’s earlier, more radical design concepts for the 30FFM resembled the Freedom-class LCS in several respects.

To be fair, these ships weren’t designed to fulfill the same operational requirements, and the LCS can attain uniquely high speeds (47 knots) and carry heavier close-defense weaponry compared to the 30FFM. But the more conservative design MHI settled on is only moderately larger—displacing 3,900 tons standard load, compared to 3,400 for a Freedom-class LCS—slightly less expensive, and all-and-all more versatile and heavily armed.

Stealthy Hull, Star Trek Command Center and Submarine Drones
A high degree of automation allows the 30FFM frigates to function with only 90 crew, compared to 220 on an Asagiri-class destroyer—which is important as Japan’s Self Defense Force must cope with a shortage of personnel. The JMSDF plans to rotate four crews between every three frigates.
