The Casco class was a large class of United States Coast Guard cutters in commission from the late 1940s through the late 1980s.[1] They saw service as weather reporting ships in the Atlantic and Pacific Oceans until the early 1970s, and some saw combat service during the Vietnam War.

Between 1941 and 1946, the United States Navy acquired 35 Barnegat-class small seaplane tenders, designated "AVP" in the Navy's alphanumeric hull numbering system and designed to logistically and administratively support a squadron of flying boats operating from undeveloped areas and, with a substantial anti-air, antisurface, and antisubmarine capability, to escort larger seaplane tenders. Most of them served during World War II, although even during the war the Navy determined the number of Barnegats to be surplus to requirements; as a result, one was completed as a catapult training ship for Navy floatplane pilots (retaining its "AVP" designation) and four were converted during construction into motor torpedo boat tenders, redesignated "AGP".[2]
After World War II, the Navy had a surplus of seaplane tenders, and the Coast Guard was looking for ships to serve on ocean stations in the Atlantic and Pacific Oceans on weather-reporting duties, also performing law enforcement and search and rescue operations as required. The Barnegats were reliable, long-ranged, and seaworthy, and had good habitability,[3] and, suitably modified, were good candidates to meet the Coast Guard's requirements; in the words of the Coast Guard's assessment of the Barnegats, "The workmanship on the vessel is generally quite superior to that observed on other vessels constructed during the war. The vessel has ample space for stores, living accommodations, ships, offices and recreational facilities. The main engine system is excellent. . . .The performance of the vessel in moderate to heavy seas is definitely superior to that of any other cutter. This vessel can be operated at higher speed without storm damage than other Coast Guard vessels."[4]
The Navy transferred three of the seaplane tenders outright to the Coast Guard in 1946; they entered service that year and in 1947. The Navy loaned twelve more seaplane tenders, the catapult training ship, and two of the motor torpedo boat tenders to the Coast Guard in 1948, and these entered Coast Guard service in 1948 and 1949; in 1966, the Navy transferred these ships outright to the Coast Guard as well. Of the ships the Coast Guard received, two had been built by the Boston Navy Yard at Boston, Massachusetts, and the rest in the state of Washington: three by Associated Shipbuilders, Inc., at Seattle, ten by Lake Washington Shipyard at Houghton, and three by the Puget Sound Navy Yard at Bremerton.
Once they were accepted into Coast Guard service, a number of changes were made to prepare the ships for ocean-station duty. A balloon shelter was added aft, a hydrographic winch and an oceanographic winch were installed, and spaces on board were devoted to oceanographic equipment.[5]
Under the alphanumeric hull classification system in use at the time, Coast Guard cutters transferred from the Navy retained their Navy classification, with a "W" added to the beginning of the classification to indicate their Coast Guard subordination. The former seaplane tenders and the former catapult training ship thus all received the classification "WAVP"; the two former motor torpedo boat tenders (AGPs), which reverted to their original "AVP" designation before transfer to the Coast Guard, also entered Coast Guard service as WAVPs. The only exception was Dexter, which initially was designated WAGC-18, but soon received a WAVP designation like the others.
In 1965, Rockaway, uniquely among the Cascos, was reclassified as an "oceanographic" ship, WAGO-377.
In 1966 the Coast Guard reclassified all of the Cascos—including Rockaway—as high endurance cutters and changed their classification to "WHEC". The ships retained the same hull numbers they had had as WAVPs.
Some Cascos later underwent additional classification changes as their roles changed in their final years in service. Unimak was a training ship (WTR-379) from 1969 to 1975 before reverting to her WHEC classification, Gresham became a "meteorological cutter" (WAGW-387) in 1970, and Rockaway became an "offshore law enforcement vessel" (WOLE-377) in 1971.
The class was named for USCGC Casco (WAVP-370), later WHEC-370, the unit with the lowest Coast Guard alphanumeric hull number. The three ships transferred outright to the Coast Guard in 1946 were given new names upon commissioning in the Coast Guard, being named after U.S. Secretaries of the Treasury. The 15 ships loaned to the Coast Guard in 1948 retained their original Navy names, and were named for islands, bays, and inlets, around the United States and the then-Territory of Alaska.
The first three ships entered service in 1946 and 1947, with the rest following in 1948 and 1949. Apart from Dexter, which was out of commission for several years in the 1950s, all remained active without break until the late 1960s and early 1970s, and one, Unimak, after a brief period out of commission in the mid-1970s, remained in service until 1988. All saw service as weather-reporting ships on ocean station patrols until the late 1960s and early 1970s except Dexter, which became the Coast Guard's United States West Coast training ship after returning to commission in 1958.
The Cascos had a variety of fates. The Navy sank five as targets in 1968 and 1969, and five others were scrapped in the early 1970s. The last survivor in Coast Guard service, Unimak, was scuttled to form an artificial reef.
Seven ships, Absecon, Chincoteague, Yakutat, Bering Strait, Castle Rock, & Cook Inlet were transferred to South Vietnam in 1971 and 1972, renamed as the RVNS Pham Ngu Lao, Lý Thường Kiệt, Trần Nhật Duật, Trần Quang Khải, Trần Bình Trọng, & Trần Quốc Toản respectively. When South Vietnam collapsed at the end of the Vietnam War in 1975, six fled to the Philippines, where two were cannibalized for spare parts and the other four entered service in the Philippine Navy, operating as Andrés Bonifacio-class frigates until the mid-1980s. The seventh ship, RVNS Pham Ngu Lao, the former Absecon, was captured by North Vietnam, appears to have remained active in the Vietnam People's Navy into the 1990s, and may remain afloat today as the last surviving Barnegat- or Casco-class ship.
