There are 13 vessels in the Famous class, and 12 vessels still in active US service in the ''Reliance'' class. The Coast Guard plans to eventually phase out the vessels in both of these cutter classes and replace them with the
Offshore Patrol Cutter as part of the
Integrated Deepwater System Program.

Service Life Extension Program
The service life extension (SLEP) program for eight cutters of the class started in July 2021 with prototype work for electrical and structural systems on the ''Seneca'' and ''Harriet Lane''. Additionally, ''Harriet Lane'' served as the prototype for the replacement of the main gun with a
Mk38 Mod 3 25mm machine gun.
The production phase of the SLEP, which will be carried out on ''Spencer'', ''Legare'', ''Campbell'', ''Forward'', ''Escanaba'' and ''Tahoma'', covers four main areas: the electrical, structural and weapons systems work prototyped on ''Seneca'' and ''Harriet Lane'' and finally replacement of the main propulsion Diesel engines.
[ The last SLEP is expected to be complete by 2030.][

''Reliance''-class cutter
The ''Reliance''-class vessels have hull numbers in the range from WMEC-615 through WMEC-630. Entering service between 1964 and 1969, the ''Reliance''-class cutters were meant to replace the cutters of the Prohibition era and were the first major cutter replacement project since the s from World War II.
The 210s (210-foot cutters) received upgrades and modifications (in a program named "Midlife Maintenance Availability" or MMA) during the 1986 through 1990 time period. The "A"-class cutters had their gas turbines removed, and all 210s had their stern transom exhaust systems replaced with a traditional stack. While this modification reduced the size of the flight deck, they were still more than capable of carrying out helicopter operations. Other modifications included enlarging the superstructure area, replacing the main armament, and increasing the fire-fighting capability of the cutters. The modifications cost approximately $20 million per cutter, well above their original cost of about $3.5 million each.
