452:(CNO), keen to increase the Navy's number of surface vessels in a cost-effective manner, committed the United States to the NATO program for a hydrofoil. The U.S. Navy proposed the PHM design as a NATO standard, with the program being led by the U.S. Navy, and an order placed for two prototypes in 1972. The Italian Navy and the West German
413:-class vessels were originally intended for NATO operations in the North Sea and Baltic Sea. Subsequently, participation by other NATO navies, including Germany and Italy, ceased and the U.S. Navy proceeded to procure six PHMs, which were highly successful in conducting coastal operations, such as

The ships were retired because they were not judged cost effective for their mission in a Navy with primarily offensive missions rather than coastal patrol.

eventually forced the Navy to complete the vessels. The difficulties in project progression forced the other involved navies to abort their participation.

When in hydrofoil form, the ships would use 1000 gallons of fuel per hour. When in surface ship form, the ships would use 100 gallons of fuel per hour.

After
Zumwalt's retirement, the Navy chose to funnel most of the money for the PHMs into larger vessels. This delayed the ongoing construction of

Germany and four by Italy.
