LATEST UPDATES

The Coast Guard awarded a $5.8 million contract to L3 Harris Arlington Training Center (LATC) on Aug. 7 to provide support, maintenance and upgrades for the C-27J Spartan operational flight trainer.


The Coast Guard transferred its fourth HC-144B, CGNR 2317, Ocean Sentry medium range surveillance aircraft outfitted with both the Ocean Sentry Refresh (OSR) modifications and the Minotaur mission system into the fleet Feb. 19, 2019. In another action, the Coast Guard delivered CGNR 2301, the first of 3 planned HC-144Bs to Air Station Corpus Christi, Texas, on Feb. 20, 2019, marking the second air station to support HC-144B operations to date.


The Coast Guard, in partnership with Naval Air Systems Command and Leonardo, came together Oct. 22-25, 2018, to conduct a critical design review on the integration and design for the 19 subsystems that comprise the missionization project for the C27-J Spartan.

The HC-144 Ocean Sentry and the C-27J make up the Coast Guard’s medium range surveillance aircraft fleet. These aircraft are instrumental in providing the capability necessary for the Coast Guard to fulfill its maritime patrol, drug and migrant interdiction, disaster response, and search and rescue missions more effectively.

Why this program?

The program was established in fiscal year 2002 to expand the Coast Guard’s patrol hour capacity and replace the aging aircraft fleet. The Coast Guard needed greater endurance to remain on-scene longer and track targets for longer periods of time. Improved sensor capability and increased passenger capacity also were identified as necessary for better mission effectiveness.

How is the fleet being acquired?

The medium range surveillance fleet includes 18 HC-144 Ocean Sentries. Ocean Sentries are capable of carrying out a wide range of Coast Guard surveillance, search and rescue, and transport missions and can be outfitted with mission system pallets, a roll-on, roll-off suite of electronic equipment that enables the aircrew to compile data from the aircraft's multiple integrated sensors to transmit and receive both classified and unclassified information from other assets including other aircraft, surface vessels and shore facilities. With multiple voice and data communications capabilities and satellite communications, the HC-144 is contributing, via a networked Command and Control system, to the common tactical picture and common operating picture. The aircraft is also equipped with a vessel automatic identification system, direction finding equipment, an electro-optical/infrared system and a multi-mode search radar to improve the Ocean Sentry’s situational awareness and responsiveness.

The Coast Guard is also in the process of receiving and missionizing 14 C-27J aircraft that are being transferred from the U.S. Air Force under the direction of the National Defense Authorization Act, Fiscal Year 2014. The multi-year project is supported by the C-27J Asset Project Office, which was stood up in Elizabeth City, N.C. The APO’s primary mission is to provide a purposeful, sequential plan to incorporate the C-27Js into Coast Guard operations. Specific functionalities of the APO include development of Coast Guard-specific operational and maintenance procedures, training plans, technical manuals, a logistics program and test and evaluation procedures. Airworthiness certifications must be obtained for all aircraft before they can be utilized. As originally delivered, the C-27Js are outfitted with weather radar and communications equipment capable of supporting transport and other Coast Guard missions. Future modifications, including specialized components such as surface search radar and electro-optical/infrared sensors, are planned to enhance the aircraft’s capability to carry out the full range of Coast Guard missions.

 

C27J

The Coast Guard is integrating 14 C-27Js into its medium range surveillance aircraft fleet, along with its HC-144 Ocean Sentries, to perform drug and migrant interdiction, disaster response, and search and rescue missions. Following missionization, the aircraft’s range, endurance, speed and payload will make it a valuable asset in addressing the Coast Guard’s maritime flight-hour gap.

Under the National Defense Authorization Act for Fiscal Year 2014, 13 C-27J aircraft were regenerated from a preserved status at Davis-Monthan Air Force Base in Tucson, Arizona. A 14th aircraft was transferred to the Coast Guard after formal acceptance by the Air Force in April 2017.

As delivered, the C-27Js are outfitted with weather radar and communications equipment capable of supporting transport and other Coast Guard missions. The Coast Guard is working with Naval Air Systems Command to determine which additional specialized equipment should be installed to enhance and expand the aircraft’s capabilities. The C-27J missionization package is based on the Minotaur mission system architecture that the Coast Guard is implementing across the rest of its fixed-wing fleet. The first Spartan entered the mission system integration process at Naval Air Station Patuxent River, Maryland, in September 2017.

The HC-27J Asset Project Office (APO), at Elizabeth City, North Carolina, oversaw the aircraft regeneration process and is assisting with missionization as well as conducting many of the acquisition duties, including development of Coast Guard-specific crew duties, procedures, technical manuals, curricula, and test and evaluation reporting.

Air Station Sacramento, California, is the first operational unit using C-27Js and began operating with its full complement of aircraft after delivery of its sixth Spartan May 1, 2017. Seven aircraft are stationed at the APO.

Characteristics

  • Length: 74 feet 6 inches
  • Wingspan: 94 feet 2 inches
  • Height: 31 feet 8 inches
  • Maximum Weight: 70,000 pounds
  • Cruise Speed: 290 knots true airspeed
  • Range: 2,675 nautical miles
  • Endurance: 12 hours

Features

  • Standardized Minotaur mission system across all Coast Guard fixed-wing aircraft (under development)
  • Military communications
  • Multimode radar
  • Large search windows
  • Night vision goggle capabilities

HC144

Eighteen HC-144 Ocean Sentry aircraft are included in the Coast Guard’s medium range surveillance fleet, along with the incoming C-27J Spartans. The fixed-wing, turboprop aircraft has an endurance of more than 10 hours and an extensive sensor capability that helps the Coast Guard fulfill its maritime patrol, drug and migrant interdiction, disaster response, and search and rescue missions more effectively.

The Ocean Sentry is particularly effective at locating objects in large search areas and vectoring other military, government and first responders to these locations. The aircraft has the capability to perform aerial delivery of search and rescue equipment, such as rafts, pumps and flares. Also, with its sophisticated command and control system, it can serve as a platform for an on-scene commander during homeland security missions.

The Ocean Sentry also features a rear ramp that allows crews to quickly reconfigure the aircraft for varied operations, including command and control, medical evacuation or passenger transport.

The Coast Guard is upgrading its HC-144A fleet to improve mission effectiveness and situational awareness through the Ocean Sentry Refresh project. Each aircraft will receive a new cockpit control and display unit, used in flight management as the primary avionics computer for communication control, navigation and equipment monitoring. Upon completion, each aircraft is redesignated as an HC-144B.

The service is also integrating the Navy’s Minotaur mission system architecture across its fixed-wing aircraft fleet. The Minotaur integration process for the prototype HC-144B began at Naval Air Station Patuxent River, Maryland, in July 2016.
