Project history: By the early 1960s interest had shifted towards the fast gunboat role, and it appeared that a relatively small hydrofoil could duplicate many of the qualities of the larger Asheville class fast gunboat. Two competitive prototypes were built under the FY66 (SCB 252) programme; the Grumman Flagstaff and the Boeing Tucumcari. At one time a follow-on class of thirty-four hydrofoils was planned, with features borrowed from both. They differed largely in propulsion, Grumman using a geared propeller with the main lifting surface forward; Boeing, water-jets with the main foil surfaces aft. Both were tested in Vietnam, returning home in 1970. Originally armed with 40mm gun forward.
Modernizations: 1971: - 1 x 1 - 81/12 mortar; + 1 x 2 - 20/70 Mk 24
Naval service: Tucumcari ran aground on a coral reef at Caballo Blanco (Vieques Island, Puerto Rico) 16.11.1972 and wrecked, plans for her repair were dropped due to high costs.
