U.S. Coast Guard Aviation Aircraft Guide: MH-60T, MH-65E, HC-130J, HC-144B and HC-27J

Coast Guard aviation succeeds because no single aircraft has to do everything. Helicopters can hover over a survivor, deploy a rescue swimmer and hoist people from the water. Fixed-wing aircraft can search enormous areas, stay on scene for hours, coordinate multiple responders and move crews or equipment over long distances. Together, they give the service a flexible system for search and rescue, maritime security, disaster response, law enforcement and national defense.

This guide explains five aircraft closely associated with modern Coast Guard aviation: the MH-60T Jayhawk, MH-65E Dolphin, HC-130J Super Hercules, HC-144B Ocean Sentry and HC-27J Spartan. It also reflects an important reality in 2026: the fleet is changing. Some aircraft are expanding their role while others are moving toward replacement or transition.

The fleet at a glance

The MH-60T and MH-65E are rotary-wing recovery aircraft. They are the aircraft most likely to perform the final rescue—hovering, hoisting and placing a rescue swimmer where needed. The HC-130J, HC-144B and HC-27J are fixed-wing surveillance and transport aircraft. They extend the Coast Guard’s reach, search large areas efficiently and provide command, control and communications support during complex cases.

MH-60T Jayhawk: long reach and heavy-lift rescue capability

The MH-60T Jayhawk is the Coast Guard’s all-weather, medium-range recovery helicopter. Its combination of range, endurance, cabin space and lifting capability makes it especially valuable for offshore rescue, disaster response and missions that require carrying additional people or equipment. Coast Guard specifications list a maximum speed of 170 knots, a range of 700 nautical miles and endurance of up to 6.5 hours.

The aircraft is equipped for demanding operational environments with surface-search radar, electro-optical and infrared sensors, hoist cameras and a digital glass cockpit. It can locate vessels or survivors, deploy a rescue swimmer, recover people by hoist and continue operating far from shore. The Coast Guard is expanding the MH-60T’s place in the fleet as it moves toward a standardized all-MH-60T rotary-wing force.

MH-65E Dolphin: fast response from shore and cutter

The MH-65E Dolphin is a short-range recovery helicopter designed for quick response. Its compact size allows it to operate from Coast Guard cutters as well as shore facilities, making it especially useful for patrol support, maritime law enforcement and rescue cases closer to the coast or a deployed ship.

The E-model upgrade was completed across the fleet in August 2024. It introduced a modernized digital cockpit, upgraded navigation and communications equipment, and an enhanced digital automatic flight-control system. Coast Guard specifications list a maximum speed of 148 knots, a range of 350 nautical miles and endurance of about three hours. Although the MH-65E remains an important operational aircraft, the service plans to transition over time to an all-MH-60T rotary-wing fleet.

HC-130J Super Hercules: long-range search, command and transport

The HC-130J Super Hercules is the Coast Guard’s long-range surveillance aircraft. It supports maritime patrol, search and rescue, heavy air transport, disaster response and on-scene command and control. Its long legs allow it to reach remote cases, remain airborne for extended periods and coordinate ships, helicopters and other aircraft over a wide search area.

Coast Guard specifications list a maximum speed of 320 knots, a range of 4,900 nautical miles and endurance exceeding 20 hours. The fleet continues to grow: the Coast Guard accepted its 19th HC-130J in April 2026 for mission-system installation, and Congress has appropriated funding for 25 aircraft. In 2026, Air Station Sacramento also began transitioning from the C-27J to the HC-130J, increasing the service’s long-range capability on the West Coast.

HC-144B Ocean Sentry: the adaptable medium-range workhorse

The HC-144B Ocean Sentry fills the medium-range surveillance role. It is smaller than the HC-130J but offers substantial endurance and a cabin that can be reconfigured for passengers, cargo, medical evacuation or mission equipment. Coast Guard specifications list a maximum cruise speed of 215 knots, a range of 2,100 nautical miles and endurance of more than 10 hours.

The B-model incorporates the Minotaur mission system along with multimode radar, electro-optical and infrared sensors, communications equipment and Automatic Identification System data. That combination helps crews build a common operating picture, detect and identify vessels, coordinate responding units and manage complex searches. Its endurance and versatility make it well suited to maritime patrol and cases where a persistent airborne command platform is needed.

HC-27J Spartan: medium-range capability in transition

The HC-27J Spartan joined the Coast Guard as a medium-range surveillance aircraft after 14 airframes were transferred from the Air Force. The aircraft brought useful speed, range, cargo capacity and a rear loading ramp to missions that included maritime patrol, search and rescue and logistics. Published Coast Guard program specifications list a maximum cruise speed of 290 knots, a range of 2,675 nautical miles and endurance of up to 12 hours.

Its place in the fleet is now changing. In 2026, the Coast Guard began transitioning Air Station Sacramento—the primary C-27J operating location—to the HC-130J. That does not erase the Spartan’s service or the missions its crews performed, but it means current readers should understand the HC-27J as part of an active fleet transition rather than assume the earlier force structure remains unchanged.

Why Coast Guard aviation needs different aircraft

A major offshore rescue may involve several of these capabilities at once. A fixed-wing aircraft can arrive quickly, search a broad area, locate the distress scene and coordinate surface units. A helicopter can then place a rescue swimmer or hoist survivors. A long-range aircraft can remain overhead as a communications and command platform, while another aircraft transports personnel or critical equipment. The real strength is not one airframe—it is the way crews and platforms work together.

That teamwork also explains why fleet transitions matter. Replacing or standardizing aircraft can improve logistics, training and availability, but the service must preserve the range, endurance, sensors, lift and cutter compatibility required by very different missions. Understanding each aircraft’s role gives a clearer picture of how Coast Guard aviation turns the promise of Semper Paratus into operational capability.
