LATEST UPDATES

The Aviation Training Center (ATC) in Mobile, Alabama, on Aug. 19, 2024, took delivery of one upgraded MH-65E helicopter, CGNR 6577, the 90th and final MH-65 aircraft to have completed service life extension work and avionics upgrades.

Air Station Port Angeles, Washington, recently took delivery of two upgraded MH-65E helicopters, CGNR 6592 on July 19, 2024, and CGNR 6569 on Aug. 1, 2024. These are the 88th and 89th of 90 MH-65 aircraft to have completed service life extension work and avionics upgrade. The air station completed its transition to the upgraded MH-65E in January 2021; these deliveries enable the station to maintain a full complement of operational MH-65E aircraft while those previously delivered undergo regularly scheduled maintenance.

Air Station Miami recently took delivery of three upgraded MH-65E helicopters – CGNR 6582 on May 28, 2024, CGNR 6568 on June 11, 2024, and CGNR 6573 on July 1, 2024. These are the 85th, 86th and 87th of 90 MH-65 aircraft to have completed service life extension work and avionics upgrades. The air station completed its transition to the upgraded MH-65E on Nov. 3, 2020. These deliveries allow the air station to maintain a full component of operational aircraft while those previously delivered undergo regularly scheduled maintenance.

MH-65 Short Range Recovery Helicopter

The Coast Guard has completed all incremental upgrades on its H-65 Dolphin short range recovery helicopter fleet, which through the life of the program added new engines, avionics and other capabilities.

Why this program?

The H-65 Dolphin has been in the Coast Guard’s inventory since 1984. The Coast Guard upgraded the helicopters with state-of-the-market enhancements that extend mission capabilities and improve their reliability and maintainability. Since 2007, the entire fleet has been equipped with new engines that add 40% more power and airborne use of force capabilities, redesignating the aircraft as MH-65s. Other upgrades included the addition of digital technology, including GPS and inertial navigation, flight control, weather radar and cockpit instruments. Additionally, the Coast Guard executed a service life extension program (SLEP) to extend the service life of the H-65 Dolphin by 10,000 flight hours.

How are the upgrades implemented?

The MH-65 conversion and sustainment program was accomplished in phases or complementary discrete segments. The Coast Guard upgraded the aircraft at the Aviation Logistics Center in Elizabeth City, North Carolina, where engineers and technical authorities on the MH-65 product line installed, tested and evaluated the new equipment. Each segment upgraded and modernized major components and sub-components and set a baseline for future upgrades in the helicopters’ mission capabilities.

Following completion of the final phase, the aircraft have been redesignated as MH-65Es. A separate discrete segment was added for the SLEP work.

The short range recovery helicopter performs search and rescue, law enforcement and homeland security missions. Certified for operation in all-weather and night-time operations, with the exception of icy conditions, the MH-65 helicopter routinely deploys aboard certified cutters providing critical manned airborne surveillance and interdiction capabilities.

Characteristics

Length (with rotor blades): 44 feet 5 inches
Rotor Diameter: 39 feet 2 inches
Height: 13 feet 3 inches
Maximum Weight: 9,480 pounds
Cruise Speed: 148 knots
Range: 350 nautical miles
Endurance: three hours

Features

40% more power and higher performance from new engines
Radar and electro-optical/infrared sensors
Capability to conduct sorties from a cutter flight deck
Capability to mount a 7.62-mm machine gun and a .50-caliber rifle
Common avionics architecture system of digital glass cockpit instruments similar to those installed on the Coast Guard’s upgraded MH-60T medium range recovery helicopter

Discrete Segments

Discrete Segment 1: In this segment, which was completed in 2007, helicopter engines were replaced with digitally controlled Turbomeca Arriel 2C2-CG engines, adding 40% more power. After completing this segment, helicopters were re-designated HH-65C.
Discrete Segment 2: The Coast Guard purchased seven new H-65 aircraft to identify and intercept non-compliant light aircraft operating within the Washington, D.C., Air Defense Identification Zone.
Discrete Segment 3: In this segment, airborne use of force capability was added, providing the ability to equip aircraft with a 7.62-mm general-purpose machine gun and a .50-caliber precision rifle to disable engines on non-compliant vessels and provide fire support for Coast Guard boarding teams. After completing this segment, helicopters were re-designated MH-65C.
Discrete Segment 4: Obsolete subsystems were replaced during this segment, such as replacing navigation systems and gyros with digital GPS and inertial navigation systems. After completing this segment, helicopters were re-designated MH-65D.
Discrete Segment 6: Remaining obsolete subsystems were modernized during this segment, including replacing analog automatic flight control with digital systems, installing digital weather radar systems, and installing digital glass cockpit instruments. After completing this segment, helicopters were re-designated MH-65E.
Discrete Segment 8: This SLEP work extended the service life of the MH-65 from 20,000 to 30,000 flight hours by replacing five of the H-65’s major structural components: the nine degree frame, canopy, center console floor assembly, floorboards and side panels. This phase did not introduce any new capabilities to the H-65 airframe; however, the upgrades of these structural components will enable fleet operations until the planned phase out in fiscal years 2035-2039. Based on current programmed usage, the 10,000-flight-hour extension per aircraft will provide a 50% increase in service life, or approximately 16 years.
