The U.S. Coast Guard is in line to get a new version of the H-60 helicopter based on the MH-60R Seahawk, which is in service with the U.S. Navy and other armed forces globally. The additional helicopters will supplement, at least initially, the Coast Guard’s aging MH-60T Jayhawks. The Coast Guard also plans to boost its overall capabilities by replacing its fleet of smaller MH-65s with H-60 variants.
Earlier this week, Naval Air Systems Command (NAVAIR) put out a contracting notice announcing its intent to award Lockheed Martin Rotary and Mission Systems a sole-source deal to design and produce an unspecified number of “MH-60R variant aircraft for the United States Coast Guard.” Lockheed Martin is the current parent company of Sikorsky, which is the prime contractor for the H-60 family of helicopters. The Navy and the Coast Guard, the latter of which is a uniformed military service that falls under the Department of Homeland Security rather than the Department of War, have a long history of cooperation on helicopter-related efforts, as well as other programs.
“The Coast Guard anticipates new aircraft procurements may be based off Sikorsky’s MH-60R aircraft, which is the maritime variant of the H-60 in active production,” the service told TWZ when reached for more information. “Differences between the MH-60T and in-production MH-60R will be addressed with Sikorsky to ensure Coast Guard aircraft are delivered with the appropriate capabilities for Coast Guard missions.”
In September, the Coast Guard had announced contracting actions intended in part to help accelerate the delivery of “new MH-60 medium-range recovery helicopters.” At that time, the service made no mention of plans to acquire a new version based on the R model.
The Coast Guard currently has some 45 MH-60Ts in inventory, which are stationed at bases around the United States. The Coast Guard also has a number of cutters, including its newest and most capable Legend class types, that can support helicopter operations.
The Jayhawks are utilized for search and rescue, as well as various law enforcement and homeland security tasks, including counter-narcotics interdiction missions. In the latter role, the helicopters can be fitted with an Airborne Use of Force (AUF) package that includes a mounted 7.62x51mm M240 machine gun, stowage for precision rifles that can be fired from the main cabin door, add-on armor protection, and additional onboard communications systems.
The bulk of the Coast Guard’s current fleet of MH-60Ts helicopters started their service lives in the early 1990s as HH-60Js, and were later upgraded to the T configuration starting in the late 2000s. The upgrades include a new glass cockpit, as well as improvements to the helicopter’s sensor suite and other capabilities. Sikorsky had developed the original HH-60J design in parallel with the HH-60H combat search and rescue helicopter for the Navy. The Coast Guard subsequently acquired a small number of additional T variants converted from second-hand SH-60 Seahawk variants.
The MH-60R is designed primarily for anti-submarine warfare and general sea control missions, and replaced various SH-60 variants when it first began entering Navy service in the mid-2000s. The Navy replaced its HH-60Hs, which were also heavily used to support U.S. special operations forces, as well as its tandem-rotor CH-46 Sea Knights, with a separate Seahawk variant, the MH-60S.
The full extent of changes that may have to be made to the MH-60R to meet Coast Guard needs, and whether the resulting configuration may receive a new designation, is unclear. The baseline R model is packed full of anti-submarine warfare and other mission systems that the Coast Guard will not need. It does have some elements that would likely be carried over directly, such as its external winch, a key feature for performing the search and rescue mission.
Certain Coast Guard-specific requirements could require more significant changes to the core MH-60R configuration. For instance, existing MH-60Ts have weather radars fitted to their noses, something that standard R variants lack. Coast Guard Jayhawks are often called upon to fly in bad weather and otherwise demanding conditions, as can be seen in the videos below.
Interestingly, one of the Navy’s MH-60Rs was embarked on the Coast Guard Legend-class National Security cutter Midgett during the biennial Rim of the Pacific exercise in 2022. That was the first time an MH-60R had been embarked on any Coast Guard vessel, and underscored the often-overlooked role the service plays in missions well beyond the shores of the United States. The Navy and the Coast Guard have been working to more deeply integrate their activities overseas in recent years, especially as part of larger efforts to challenge China in the Indo-Pacific region.
The new H-60s, whatever their exact configuration might be, are part of a larger Coast Guard effort to modernize and transform its helicopter fleets that has already ongoing for years now. The service’s existing MH-60T fleet is being put through a service life extension program (SLEP), which is intended to keep them flying into the 2040s. As part of the current SLEP effort, MH-60Ts are receiving a completely new central fuselage ‘hull.’ The Coast Guard had previously used hulls taken from retired Seahawks with lower total flight hours to help extend the life of its T variants.
The Coast Guard has said in the past that it also plans to “organically produce” 36 additional T variants from second-hand Seahawks, though the current status of that effort is unclear.
“As part of the U.S. Coast Guard’s service life extension program (SLEP), we continue to build replacement MH-60T Jayhawk hulls at our Troy, Alabama, facility,” Lockheed Martin told TWZ in response to questions about how the plans to acquire new MH-60R-based variants might impact the SLEP work and other work it is doing for the Coast Guard.
The Coast Guard also currently plans to retire all of its remaining MH-65 helicopters and replace them with H-60 variants, a process it expects to be complete by the early 2040s. The service currently has some 94 MH-65s, which are variants of the French-made AS365 Dauphin. Originally developed in the 1970s by Aerospatiale, the design subsequently came under the umbrella of Eurocopter and then Airbus Helicopters. The AS365 line is no longer in production, with the last example having been delivered in 2021.
The Coast Guard has argued that transitioning to a pure H-60 fleet will offer more capability and the benefits of a still-in-production design, but has faced some pushback from Congress. In January of this year, Airbus Helicopters announced that it had signed a Memorandum of Understanding (MOU) with the Coast Guard for continued support for the MH-65s at least through 2037.
New Coast Guard H-60s based on the R variant would also be able to leverage the Navy’s existing logistics and sustainment ecosystem for those helicopters. The Navy expects to keep flying its MH-60Rs well into the 2030s, at least.
How exactly the Coast Guard ultimately proceeds with its larger helicopter modernization efforts remains to be seen, but those plans now include a new service-specific version of the H-60.
