1:96 Scale 3D Printable Model

Build a Legend: The Iconic “Secretary Class” High Endurance Cutter

For nearly five decades, the Hamilton-class cutters were the backbone of the U.S. Coast Guard’s blue-water operations, patrolling the world’s oceans from the Arctic to the South China Sea, from the Bering Sea to the Caribbean. Known colloquially as “378s” (after their 378-foot length) or the “Secretary class” (most were named after U.S. Treasury Secretaries), these vessels represented a revolutionary leap forward in Coast Guard capability when they entered service beginning in 1967.

Now you can build your own meticulously detailed 1:96 scale replica of these historic vessels — a 1.2-meter model that captures the essence of America’s most versatile maritime platform.

Historical Significance: Ships Ahead of Their Time

Cold War Innovation

Commissioned between 1967 and 1972, the Hamilton-class cutters were designed during the Cold War era to replace aging World War II-era vessels. While similarly sized Navy surface combatants were still built with steam propulsion, the Hamilton class had a revolutionary combined diesel or gas turbine (CODOG) powerplant — the first U.S. military vessels to employ this technology.

Technical Specifications of the Real Ships:

Length: 378 feet (115 meters)
Displacement: 3,250 tons
Speed: 29 knots (using gas turbines), 20 knots cruising (diesel)
Range: 12,000 nautical miles at cruising speed
Crew: 164 personnel (15 officers, 149 enlisted)
Propulsion: Two Fairbanks Morse diesel engines + Two Pratt & Whitney gas turbines (same type as Boeing 707 airliners)
Special Features: Controllable-pitch propellers, retractable 360-degree bow thruster

Multi-Mission Versatility

The Hamilton-class cutters were designed to be highly versatile platforms capable of performing various operations, including maritime law enforcement, search and rescue, oceanographic research, and defense operations. Their capabilities included:

Search and Rescue: Extended endurance for mid-ocean rescue operations
Law Enforcement: Drug interdiction, fisheries enforcement, migrant interdiction
Military Operations: Anti-submarine warfare, convoy escort, integrated operations with Navy Carrier Battle Groups
Oceanographic Research: Wet and dry laboratories, bathythermograph sensors, weather balloon shelter
Ocean Station Program: Until 1977, provided meteorological data and navigational aids for trans-oceanic crossings

Combat Evolution

Originally equipped for anti-submarine warfare (ASW), they were armed with a 5″/38 naval gun, two 81mm mortars, two .50 caliber machine guns, two MK 10 Hedgehogs, two MK 32 torpedo tube systems, and Nixie torpedo countermeasures.

In the 1980s-1992, the entire class was modernized through the Fleet Renovation and Modernization (FRAM) program, which included:

Replacement of the 5-inch gun with the OTO Melara 76mm
Installation of Phalanx CIWS for missile defense
Harpoon anti-ship missiles (later removed post-Cold War)
MK 92 fire control system
SeaWatch command and control system
Modern radar suites (AN/SPS-40 or SPS-49 air-search, AN/SPS-73 surface-search)
MK 38 25mm chain guns

Global Service and Legacy

The Original Fleet (U.S. Coast Guard): All twelve Hamilton-class cutters served with distinction:

USCGC Hamilton (WHEC-715) – Lead ship, commissioned March 18, 1967
USCGC Dallas (WHEC-716)
USCGC Mellon (WHEC-717)
USCGC Chase (WHEC-718)
USCGC Boutwell (WHEC-719)
USCGC Sherman (WHEC-720)
USCGC Gallatin (WHEC-721)
USCGC Morgenthau (WHEC-722)
USCGC Rush (WHEC-723)
USCGC Munro (WHEC-724)* – Decommissioned April 2021, ending the era
USCGC Jarvis (WHEC-725)*
USCGC Midgett (WHEC-726)*

*Named after Coast Guard heroes (the “Hero class”)

Operational Highlights:

Vietnam War: Multiple cutters supported Operation Market Time, patrolling the South Vietnamese coastline
Operation Urgent Fury: Grenada intervention (1983)
Persian Gulf Operations: Integrated with Navy battle groups
Drug Interdiction: Billions of dollars in narcotics seized over their service lives
Maritime Law Enforcement: Fisheries protection, migrant rescue, sovereignty patrols

Second Lives Around the World:

Following decommissioning (2011-2021), most Hamilton-class cutters were transferred to allied nations through the Excess Defense Articles program, where they continue to serve:

Philippines (Philippine Navy):

BRP Gregorio del Pilar (PS-15) – ex-USCGC Hamilton
BRP Ramon Alcaraz (PS-16) – ex-USCGC Dallas
BRP Andres Bonifacio (PS-17) – ex-USCGC Boutwell

Bangladesh (Bangladesh Navy):

BNS Somudra Joy (F-28) – ex-USCGC Rush
BNS Somudra Avijan (F-29) – ex-USCGC Jarvis

Nigeria (Nigerian Navy):

NNS Thunder (F90) – ex-USCGC Chase

Vietnam (Vietnam Coast Guard):

CSB 8020 – ex-USCGC Morgenthau

Sri Lanka Navy:

SLNS Sayurala (P-623) – ex-USCGC Sherman
SLNS Vijayabahu (P-627) – ex-USCGC Douglas Munro

The 3D Printable Model: Engineering Meets Accessibility
