US Coast Guard Expands Aircraft Fleet with New Engines and Radar Systems
US Coast Guard invests over $28 million in engines and radar to modernize MH-60T and HC-130J fleets, enhancing maritime security and surveillance.
The U.S. Coast Guard is undergoing a significant modernization of its aviation fleet, marked by recent contract awards exceeding $28 million for new engines and advanced radar systems. These acquisitions are central to a broader transformation that will reshape the Coast Guard’s maritime aviation capabilities in the coming decades. The $14.3 million procurement of thirteen General Electric T700 engines and a $13.9 million contract for three AN/APY-11 multi-mode radar systems reflect the acceleration of long-planned recapitalization efforts, fueled by legislative support from the One Big Beautiful Bill Act. This initiative addresses the challenges of aging aircraft, deferred maintenance, and evolving operational demands, setting the stage for a more efficient, capable, and technologically advanced fleet.
The Coast Guard’s modernization strategy extends beyond equipment replacement. It aims to consolidate rotary-wing operations to a single platform, expand fixed-wing surveillance capabilities, and enhance mission system integration. These changes are designed to meet the security, search and rescue, and law enforcement needs of the 21st century, while overcoming the limitations of an aging and diverse fleet.
As the Coast Guard prepares for the future, the implications of these investments will be felt across its eleven statutory missions, from drug interdiction to disaster response. The modernization effort is not only a response to immediate operational needs but also a proactive step toward ensuring long-term maritime security and readiness.
The Coast Guard’s current aviation fleet reflects decades of budget constraints and evolving mission requirements. The rotary-wing component consists of 48 MH-60T Jayhawk helicopters and 98 MH-65 Dolphin Helicopters, totaling 146 rotary aircraft. The MH-60T, in service since 1990, has accumulated over 730,430 flight hours and participated in more than 48,300 search and rescue missions, saving nearly 12,000 lives over its operational history.
Maintaining this diverse fleet has become increasingly challenging. The MH-65 Dolphin, a short-range recovery helicopter, has faced sustainability issues since the retirement of the Airbus Helicopter H155 production line in 2018, which limited access to critical spare parts. This has led to higher maintenance costs and reduced aircraft availability, prompting Coast Guard leadership to consider consolidating to a single rotary-wing platform for operational and fiscal efficiency.
The fixed-wing fleet faces similar challenges. The Coast Guard operates legacy HC-130H aircraft, some dating back to 1959, alongside newer HC-130J models introduced in 2008. The HC-130J offers a 20% increase in speed and altitude and a 40% greater range compared to its predecessor, along with improved avionics and navigation systems. The service plans to replace all HC-130H aircraft with the HC-130J by 2027, aiming for a fleet of 22 missionized HC-130Js.
In September 2024, the Coast Guard placed a $14.3 million order for thirteen General Electric T700 engines to support the MH-60 helicopter fleet. These engines are essential for accelerating the transition of multiple air stations from MH-65E to MH-60T operations, aligning with the broader fleet consolidation strategy and ensuring continued operational capacity.
The T700 engine is part of a larger Department of Defense acquisition strategy, with a $1.1 billion contract awarded to GE Aerospace for up to 950 engines for use across the Army, Navy, Air Force, and Coast Guard. This joint procurement approach leverages economies of scale and ensures a reliable supply chain for critical components, with over 24,000 T700 engines delivered globally to date. The new engines will play a crucial role in supporting the Coast Guard’s planned expansion from 48 to 127 MH-60T helicopters, providing the propulsion reliability required for extended missions and increased operational tempo.
The Coast Guard also awarded a $13.9 million contract to L3 Harris Technologies for three AN/APY-11 multi-mode radar systems, to be installed on future HC-130J aircraft during the Minotaur missionization process. These radars enhance long-range surveillance capabilities, supporting missions such as search and rescue, drug interdiction, and maritime domain awareness.
The AN/APY-11 radar offers advanced features, including detection and tracking of ships, aircraft, ground vehicles, and Search and Rescue transponders, as well as high-resolution Synthetic Aperture Radar imaging. Its 360-degree coverage and adaptability for installation on various aircraft types make it a versatile tool for the Coast Guard’s diverse operational needs.
The integration of these radars with the Minotaur mission system ensures seamless collection and processing of sensor data, enhancing mission effectiveness and situational awareness for aircrews and command centers alike.
“The Coast Guard’s investment in advanced propulsion and surveillance systems is a pivotal step in ensuring operational readiness and mission success across its expanding fleet.”
The Coast Guard’s MH-60T modernization is one of the most ambitious rotary-wing recapitalization efforts in its history. The Service Life Extension Program (SLEP), initiated in 2017, addresses the impending end-of-life for most of the current MH-60T fleet, which averages 16,000 flight hours per aircraft and is approaching the 20,000-hour design limit.
The SLEP involves a comprehensive rebuild of each helicopter at the Aviation Logistics Center in Elizabeth City, North Carolina. Technicians strip the aircraft to the airframe, replace dynamic components, upgrade avionics, and install new engines, effectively extending the service life and enhancing performance. Airframes are sourced from retired Navy H-60s and new builds from Sikorsky, with the first new airframe delivered in November 2023.
Alongside the SLEP, the Coast Guard plans to grow the MH-60T fleet to 127 helicopters, replacing all MH-65s. This expansion will occur in phases, with the first increment converting eight air stations and subsequent increments extending into the early 2040s. The transition requires careful management of procurement, training, and infrastructure to maintain operational coverage during the shift.
The HC-130J program is central to the Coast Guard’s fixed-wing modernization. Seventeen HC-130J aircraft are currently in service, with plans to reach a fleet of 22 fully missionized units. The HC-130J offers improved speed, range, and altitude over the legacy HC-130H, along with state-of-the-art avionics and mission systems. Missionization of the HC-130J involves integrating the Minotaur system, which provides advanced command, control, communications, and intelligence capabilities. This system enables real-time data sharing, sensor fusion, and enhanced situational awareness, supporting a broad range of missions from search and rescue to law enforcement.
The Coast Guard’s latest HC-130J, accepted in January 2025, demonstrates the ongoing commitment to upgrading the fleet with the latest technology. These Military-Aircraft have collectively surpassed 100,000 flight hours, underscoring their reliability and operational value.
“The HC-130J’s advanced capabilities and mission system integration are critical to the Coast Guard’s ability to project maritime security and respond to evolving threats.”
Consolidating the rotary-wing fleet to the MH-60T platform is a strategic move aimed at improving operational efficiency, reducing maintenance complexity, and enhancing mission capability. The MH-60T offers more than double the range and payload of the MH-65, along with superior avionics and survivability features.
This consolidation simplifies training and logistics, as crews and maintenance personnel can focus on a single platform, reducing costs and improving flexibility. The end of MH-65 production has made continued support of that platform increasingly untenable, further justifying the shift to an all-MH-60T fleet.
The transition is not without challenges. As of late 2024, nearly 18% of the MH-60T fleet was grounded due to exceeding service life limits, and most remaining aircraft were approaching critical flight hour thresholds. The Coast Guard must balance ongoing operations with accelerated SLEP activities and new airframe procurement to maintain readiness.
The One Big Beautiful Bill Act represents the largest single investment in Coast Guard history, providing nearly $25 billion for fleet recapitalization, infrastructure, and technology upgrades. This includes over $2.2 billion for rotary-wing aircraft and $1.1 billion for fixed-wing procurement, enabling the acquisition of more than 40 MH-60 helicopters and six C-130J aircraft.
The fiscal year 2026 Coast Guard budget request totals $14.494 billion, with $184 million allocated for aviation recapitalization. Unfunded priorities for FY25 include $138.5 million for one missionized HC-130J and $153.5 million for outfitting five MH-60Ts, highlighting the ongoing need for supplemental funding to meet modernization goals.
Legislative and budgetary support is crucial for sustaining the pace of modernization, addressing unfunded requirements, and ensuring the Coast Guard remains capable of fulfilling its statutory missions. Mission system integration is a cornerstone of the Coast Guard’s modernization strategy. The Minotaur Family of Services provides a unified platform for collecting, processing, and displaying intelligence, surveillance, and reconnaissance data across all aircraft. This system leverages artificial intelligence and machine learning to enhance situational awareness and operational decision-making.
The AN/APY-11 radar system, selected as part of the Minotaur suite, extends detection and tracking capabilities for ships, aircraft, and ground vehicles, and supports high-resolution imaging for search and rescue operations. Its deployment across the HC-130J fleet and other platforms ensures consistency and interoperability in mission execution.
These technological advancements enable the Coast Guard to respond more effectively to emerging threats, conduct complex operations, and share information seamlessly with partner agencies.
The modernization initiative faces several challenges, including aircraft availability constraints, limited maintenance and manufacturing capacity, and the complexity of transitioning air stations over an extended period. The Aviation Logistics Center’s throughput limits the number of MH-60Ts that can be rebuilt or converted at any given time, potentially slowing the pace of fleet expansion.
Service life restrictions have already grounded a portion of the MH-60T fleet, placing additional strain on remaining helicopters. The Coast Guard is working to manage these issues through accelerated SLEP activities, new airframe procurement, and careful planning of air station transitions, which are expected to continue into the early 2040s.
Maintaining operational capability during this period will require effective resource management, workforce development, and sustained legislative support to address emerging needs and unforeseen challenges.
The Coast Guard’s aircraft modernization is a transformative effort with far-reaching implications for U.S. maritime security. By standardizing platforms, integrating advanced mission systems, and expanding surveillance capabilities, the service is positioning itself to address contemporary threats and operational demands more effectively.
Future developments are likely to include increased use of unmanned aircraft systems, further integration of artificial intelligence, and continued collaboration with other military and homeland security agencies. The Coast Guard’s commitment to maintaining a robust, technologically advanced aviation fleet will be essential for safeguarding national interests in an increasingly complex maritime environment. The Coast Guard’s recent investments in aircraft engines and radar systems are pivotal steps in a comprehensive modernization initiative that will define the service’s aviation capabilities for decades. Backed by historic funding levels and legislative support, these acquisitions accelerate fleet expansion, enhance operational readiness, and introduce cutting-edge technology across both rotary and fixed-wing platforms.
The challenges of transitioning to a new fleet structure, managing aging assets, and integrating advanced mission systems are significant but surmountable with sustained commitment and effective management. The Coast Guard’s strategic approach positions it to meet current and future mission requirements, ensuring continued leadership in maritime safety, security, and stewardship.

South Korea Grounds AH-1S Cobra Helicopters After Fatal Crash
South Korea suspends AH-1S Cobra helicopter operations following a fatal training crash amid delays in fleet replacement.
This article summarizes reporting by South China Morning Post and official statements from the South Korean military.
The South Korean military has ordered an immediate suspension of all AH-1S Cobra helicopters operations following a fatal accident on Monday morning. According to reporting by the South China Morning Post (SCMP), the crash occurred in Gapyeong and resulted in the deaths of two crew members. The grounding order remains in effect pending a comprehensive investigation into the cause of the incident.
The tragedy has renewed scrutiny over the Republic of Korea Army’s aging fleet of attack helicopters, many of which have surpassed their original intended service life. Military officials confirmed that the aircraft involved was conducting training maneuvers at the time of the accident.
The crash took place at approximately 11:04 AM KST on February 9, 2026. The aircraft, an AH-1S Cobra operated by the Army’s 15th Aviation Group, went down on a riverbank in Gapyeong County, located roughly 55 kilometers northeast of Seoul.
According to military briefings, the two crew members on board, both Warrant Officers, were recovered from the wreckage in cardiac arrest. They were transported to a nearby hospital but were subsequently pronounced dead.
Preliminary reports indicate the crew was engaged in “emergency landing procedures.” In rotorcraft aviation, this typically refers to autorotation training, a high-risk maneuver where pilots simulate engine failure to glide the helicopter safely to the ground using the energy stored in the spinning rotors. While standard for pilot certification, autorotation requires precise handling, particularly during the final “flare” phase near the ground.
The AH-1S Cobra has been a staple of South Korea’s anti-tank capabilities since its introduction between 1988 and 1991. However, the fleet is widely considered obsolete by modern standards. Estimates suggest the Army still operates between 55 and 70 of these airframes.
According to defense procurement plans previously released by the government, the AH-1S fleet was scheduled for retirement by 2024. The continued operation of these helicopters in 2026 points to significant delays in the full deployment of replacement platforms, specifically the AH-64E Apache Guardian and the domestically produced KAI LAH (Light Armed Helicopter). This is not the first time the aging Cobra fleet has faced safety questions. In August 2018, the fleet was grounded after a catastrophic mechanical failure in Yongin. During that incident, a main rotor blade separated from the fuselage during takeoff, leading to a crash landing. That failure was later attributed to a defect in the rotor strap assembly, highlighting the structural fatigue inherent in airframes that have been in service for nearly four decades.

AirPro News Analysis
The crash in Gapyeong underscores a critical dilemma facing modernizing militaries: the necessity of training on “high-risk” airframes while awaiting delayed replacements. Autorotation training is inherently dangerous even in modern aircraft; performing these stress-inducing maneuvers on helicopters approaching 40 years of service compounds the risk profile significantly.
We anticipate this incident will accelerate political pressure on the Ministry of National Defense to expedite the retirement of the remaining AH-1S Cobras. While South Korea has become a major exporter of advanced defense hardware, such as the K2 tank and FA-50 light combat aircraft, the domestic reliance on Vietnam-era derivative helicopters creates a stark capability gap. The tragedy may force the military to prioritize the delivery of the KAI LAH to prevent further loss of life among aircrews operating obsolete equipment.

Grid Aero Raises $20M to Deploy Long-Range Autonomous Airlift
Grid Aero secures $20M Series A funding to develop the “Lifter-Lite,” a long-range autonomous aircraft for military logistics in the Indo-Pacific.
This article is based on an official press release from Grid Aero.
Grid Aero, a California-based aerospace Startups, announced on January 26, 2026, that it has raised $20 million in Series A funding. The round was led by Bison Ventures and Geodesic Capital, with participation from Stony Lonesome Group, Alumni Ventures, Ubiquity Ventures, Calibrate Ventures, and Commonweal Ventures. The capital will be used to transition the company’s “Lifter-Lite” autonomous aircraft from prototype to a fielded platform, specifically targeting military logistics challenges in the Indo-Pacific region.
Unlike many entrants in the autonomous aviation sector that focus on electric propulsion, Grid Aero has developed a clean-sheet, conventional-fuel aircraft designed to address the “tyranny of distance.” By utilizing standard Jet-A fuel and a rugged fixed-wing design, the company aims to provide a heavy-lift solution capable of operating without traditional runway infrastructure.
According to the company’s announcement, the flagship “Lifter-Lite” aircraft prioritizes range and payload capacity over novel propulsion methods. The system is engineered to carry between 1,000 and 8,000 pounds of cargo, with a maximum range of up to 2,000 miles. This range capability allows for trans-oceanic flights, such as routes from Guam to Japan, which are critical for Pacific theater operations.
The aircraft utilizes a conventional turboprop engine, a strategic choice intended to ensure compatibility with existing military fuel supply chains. The design features Short Takeoff and Landing (STOL) capabilities, enabling operations from dirt strips, highways, or damaged runways where standard cargo planes cannot land.
Grid Aero was founded in 2024 by CEO Arthur Dubois and CTO Chinmay Patel. Dubois previously served as Director of Engineering at Xwing and was an early engineer at Joby Aviation. Patel, who holds a PhD in Aeronautics and Astronautics from Stanford, brings experience from Zee Aero (Kitty Hawk). The leadership team emphasizes a shift away from the “electric hype” of the urban air mobility sector toward pragmatic, physics-based solutions for defense logistics.
“We are building the pickup truck of the skies, a rugged, affordable, and autonomous logistics network capable of operating in austere environments.”
, Grid Aero Mission Statement
The Investments from Geodesic Capital, a firm known for fostering U.S.-Japan collaboration, highlights the strategic focus on the Indo-Pacific. The Department of Defense (DoD) has identified logistics as a primary vulnerability in potential conflicts where traditional supply lines may be contested. Grid Aero positions its technology as an “attritable” asset, low-cost, unmanned systems that can be deployed in volume without risking human crews. The Shift to Pragmatic Propulsion
While the broader autonomous aviation market has largely chased the promise of electric Vertical Takeoff and Landing (eVTOL) technologies, Grid Aero’s successful Series A raise signals a growing investor appetite for pragmatic, mission-specific engineering. Electric propulsion currently struggles with energy density, limiting most eVTOLs to ranges under 200 miles, insufficient for the vast distances of the Pacific.
By opting for a conventional turboprop engine, Grid Aero bypasses the battery bottleneck entirely. This decision allows the “Lifter-Lite” to integrate immediately into existing defense infrastructure (using Jet-A fuel) while offering ranges that are an order of magnitude higher than its electric competitors. For military buyers, the ability to repair an aluminum airframe in the field is often more valuable than the theoretical efficiency of composite electric platforms.
What is the primary use case for Grid Aero’s aircraft?
The aircraft is designed for “contested logistics,” delivering heavy cargo (1,000–8,000 lbs) over long ranges (up to 2,000 miles) to areas without standard runways, such as islands or forward operating bases.
Why does Grid Aero use conventional fuel instead of electric power?
Conventional Jet-A fuel offers significantly higher energy density than current battery technology, enabling the long ranges required for operations in the Pacific. It also ensures compatibility with existing military logistics chains.
Who are the lead investors in this round? The Series A round was led by Bison Ventures, a deep-tech VC firm, and Geodesic Capital, which specializes in U.S.-Japan expansion and security collaboration.
Is the aircraft fully autonomous?
Yes, the system is designed for fully autonomous flight operations, allowing for “fleet-scale” management where a single operator can oversee multiple aircraft simultaneously.

Apogee Aerospace Signs $420M Deal for Albatross Amphibious Aircraft
Apogee Aerospace partners with Australia’s AAI to purchase 15 Albatross 2.0 amphibious planes and invest in India’s seaplane infrastructure.
This article summarizes reporting by The Economic Times.
In a significant development for India’s regional and maritime aviation sectors, Apogee Aerospace Pvt Ltd has signed a definitive agreement with Australia’s Amphibian Aerospace Industries (AAI). According to reporting by The Economic Times, the deal, finalized on February 5, 2026, is valued at approximately Rs 3,500 crore ($420 million) and involves the purchase of 15 Albatross 2.0 amphibian aircraft.
The partnership extends beyond a simple acquisition. Reports indicate that Apogee Aerospace will invest an additional Rs 500 crore ($60 million) to develop a domestic ecosystem for seaplanes in India. This infrastructure commitment includes a final assembly line, a Maintenance, Repair, and Overhaul (MRO) facility, and a pilot training center. The move appears strategically timed to align with the Indian Navy’s recent interest in acquiring amphibious capabilities.
The agreement outlines a comprehensive collaboration between the Indian entity and the Darwin-based manufacturer. As detailed in the report, Apogee Aerospace, a special purpose vehicle of the deep-tech defense firm Apogee C4i LLP, has secured 15 units of the G-111T Albatross. This modernized aircraft is a “revival” of the Grumman HU-16, a platform historically utilized for open-ocean rescue missions.
To cement the partnership, Apogee has reportedly invested $7 million (Rs 65 crore) directly into AAI’s parent company, Amphibian Aircraft Holdings. This equity stake grants the Indian firm a long-term interest in the Original Equipment Manufacturer (OEM). According to the timeline provided in the reporting, the first aircraft is expected to enter the Indian market within 18 to 24 months, with a demonstration aircraft likely arriving within six months.
A central component of the deal is the focus on “Make in India” initiatives. The Rs 500 crore investment is designated for establishing local capabilities that would allow Apogee to service the fleet domestically. This aligns with the Indian government’s Union Budget 2026-27, which explicitly offered incentives for indigenous seaplane manufacturing and viability gap funding for operators.
The aircraft at the center of this procurement is the Albatross 2.0, also known as the G-111T. While based on a legacy airframe, the new variants are being rebuilt in Darwin with significant modernizations. The Economic Times notes that AAI holds the type certificate for the aircraft, which is the only FAA and EASA-certified transport-category amphibian in its class.
Key upgrades to the platform include: The timing of this commercial agreement coincides with a major defense procurement opportunity. On January 10–12, 2026, the Indian Ministry of Defence (MoD) issued a Request for Information (RFI) seeking to wet-lease four amphibious aircraft for the Indian Navy. The Navy requires these assets for SAR operations, island logistics in the Andaman & Nicobar and Lakshadweep archipelagos, and maritime surveillance.
Industry observers suggest that the Apogee-AAI partnership intends to bid for this contract against established global competitors, most notably Japan’s ShinMaywa. The ShinMaywa US-2 has been evaluated by the Indian Navy for over a decade, but high unit costs, estimated at over $110 million per aircraft, have historically stalled acquisition efforts. In contrast, the Albatross 2.0 is positioned as a cost-effective alternative, with a claimed unit cost significantly lower than its Japanese competitor.
We view this deal as a calculated gamble by Apogee Aerospace to disrupt a defense procurement process that has been stagnant for years. By securing a commercial order and investing in local MRO, Apogee is likely attempting to present a “sovereign industrial capability” argument to the Ministry of Defence. This approach addresses two critical pain points for Indian defense planners: cost and indigenization.
However, risks remain. While the ShinMaywa US-2 is a proven, currently operational platform with extreme rough-sea capabilities, the Albatross 2.0 is effectively a remanufactured legacy aircraft from a company that is still ramping up production. The Indian Navy’s RFI calls for an immediate wet-lease solution. Whether AAI can meet the operational readiness requirements with a production line that is still maturing will be the key factor in the upcoming bid evaluation. The promise of a demo aircraft in six months will be the first real test of this partnership’s viability.
