Combat Search and Rescue: HH-60W Jolly Green II Penetrating Anti-Access Bubbles
When a pilot goes down in hostile territory, every second counts — and the battlefield they fall into determines whether rescue is even possible. Modern near-peer adversaries have spent decades studying how U.S. forces project power, and they’ve built elaborate defensive architectures specifically designed to make rescue operations a near-suicidal proposition. These systems, known as Anti-Access/Area Denial (A2/AD) bubbles, represent one of the most serious challenges facing military aviation today.
Enter the HH-60W Jolly Green II — the U.S. Air Force’s purpose-built answer to this evolving threat. Developed by Sikorsky, a Lockheed Martin company, this Combat Rescue Helicopter (CRH) is designed from the ground up to fly into the most dangerous airspace on earth, recover isolated personnel, and come back out alive. Understanding how it does that requires looking closely at both the threat it faces and the sophisticated systems engineered to defeat it.
This isn’t just a story about a new helicopter. It’s a story about what it takes to maintain the foundational military promise that no service member will be left behind — even when adversaries have done everything in their power to make that promise impossible to keep.
Understanding Anti-Access/Area Denial (A2/AD) Bubbles
Before examining the HH-60W’s capabilities, it’s worth unpacking exactly what “penetrating anti-access bubbles” actually means. The term gets thrown around frequently in defense circles, but the tactical reality is both specific and sobering.
What Is A2/AD and Why Does It Matter?
Anti-Access/Area Denial is a military strategy designed to prevent or significantly degrade an adversary’s ability to enter or operate within a defined geographic area. Think of it as a layered, overlapping defensive umbrella — one that combines multiple threat systems to create a kill zone where operating conventional aircraft becomes extraordinarily dangerous.
Near-peer adversaries like China and Russia have invested heavily in A2/AD architectures over the past two decades. The goal isn’t just to shoot down aircraft — it’s to make the threat of doing so credible enough to deter operations altogether.
The Key Layers of an A2/AD Bubble
A modern A2/AD environment isn’t a single threat — it’s a web of interconnected systems:
– Advanced Surface-to-Air Missile (SAM) systems: Platforms like Russia’s S-400 Triumf or China’s HQ-9 can engage targets at ranges exceeding 250 miles at altitudes from treetop level to near-space. These systems are highly mobile and increasingly difficult to pre-emptively destroy.
– Sophisticated Electronic Warfare (EW): Modern EW suites can jam communications, spoof GPS signals, blind radar systems, and disrupt the data links that aircraft depend on for navigation and coordination.
– Long-range precision fires: Ballistic and cruise missiles that can strike airbases and support infrastructure far from the front lines, complicating any rescue mission before it even launches.
– Integrated Air Defense Networks (IADN): The truly dangerous element is how these systems talk to each other. Radar networks, command nodes, and shooters are networked together, creating overlapping coverage that eliminates gaps an aircraft might exploit.
– Cyber warfare: Attacks targeting communications and navigation infrastructure can leave rescue crews flying blind and unable to coordinate with either command or the isolated personnel they’re trying to reach.
For a slow-moving search and rescue helicopter attempting to penetrate this environment and loiter long enough to hoist a survivor — the challenge is immense. This is precisely the gap the HH-60W was built to address.
The HH-60W Jolly Green II: A New Era for CSAR
Replacing a Legend
The HH-60W takes its operational lineage from some of the most storied aircraft in U.S. military history. The “Jolly Green” nickname traces directly back to the HH-3E Jolly Green Giant and HH-53 Super Jolly Green Giant helicopters that performed remarkable rescues during the Vietnam War. The current aircraft it replaces — the HH-60G Pave Hawk — has served since the 1980s and logged combat hours across conflicts from Panama to Afghanistan.
But the HH-60G was designed for a different threat environment. Its range limitations required reliance on external fuel tanks that reduced payload and increased vulnerability. Its defensive systems, avionics, and communications architecture were designed to counter Cold War-era threats — not the integrated, networked A2/AD systems that China and Russia have fielded in the decades since.
The HH-60G simply wasn’t built to penetrate the kind of layered defenses a conflict with a near-peer adversary would present. Sending crews into those environments with it would have been unacceptably risky.
Development and Program Basics
The HH-60W conducted its first flight on May 17, 2019, and the program designated it the official Combat Rescue Helicopter (CRH) for the U.S. Air Force. The original program of record called for 113 aircraft, with the first operational unit standing up at the 23rd Wing at Moody Air Force Base, Georgia. Unit cost has been reported at approximately $50 million per aircraft, though this figure has varied depending on production batch and configuration.
The nickname “Jolly Green II” was a deliberate choice — a nod to the legacy these crews carry into some of the most dangerous missions in modern warfare.
HH-60W Capabilities Designed for A2/AD Penetration
What separates the HH-60W from its predecessor isn’t any single feature — it’s the integration of multiple advanced systems that collectively allow it to survive and operate inside anti-access bubbles. Each capability directly counters a specific layer of the A2/AD threat.
Enhanced Survivability: The Integrated Defensive System
The most critical advancement is the HH-60W’s Integrated Defensive System (IDS). This isn’t a collection of bolt-on afterthoughts — it’s a unified, deeply integrated suite designed to detect, track, and defeat threats in real time.
The IDS includes:
– Missile Warning Systems (MWS): Detect and classify incoming missile threats, triggering automated countermeasures responses.
– Radar Warning Receivers (RWR): Alert crews when enemy radar systems are painting the aircraft, giving them critical seconds to maneuver or deploy countermeasures.
– Countermeasures Dispensers: Deploy chaff to defeat radar-guided missiles and flares to defeat infrared-guided threats.
– Ballistic Protection: Hardened armor capable of withstanding small arms fire and larger caliber threats during low-altitude penetration.
Against an A2/AD environment saturated with advanced SAM systems and MANPADS (Man-Portable Air Defense Systems), this integrated approach is not optional — it’s the difference between completing a mission and becoming the second rescue objective.
Extended Range: Defeating Distance as a Threat
One of the most strategically significant improvements in the HH-60W is its doubled internal fuel capacity compared to the HH-60G. This change is more consequential than it might initially appear.
In an A2/AD environment, forward operating bases and tanker aircraft are themselves at risk from long-range precision fires. A helicopter that requires frequent refueling stops deep in contested territory is enormously vulnerable. By doubling internal fuel capacity, the HH-60W extends its operational radius significantly without relying on external tanks that reduce agility and increase drag.
Combined with aerial refueling capability — allowing it to top off from HC-130J Combat King II tankers during extended missions — the Jolly Green II can reach isolated personnel at distances the HH-60G simply couldn’t cover. In a Pacific conflict scenario where distances are vast and forward bases are few, this isn’t a nice-to-have. It’s a mission-enabling requirement.
Advanced Avionics and Navigation: Operating When GPS Is Denied
Electronic warfare within an A2/AD bubble specifically targets navigation systems. GPS jamming and spoofing are now established tactics in any sophisticated adversary’s EW arsenal. An aircraft that depends entirely on GPS for navigation becomes unreliable — or worse, dangerous — the moment that jamming begins.
The HH-60W’s Integrated Mission System addresses this through multiple complementary navigation approaches:
– Advanced Precision Navigation: The system can operate effectively in GPS-degraded or GPS-denied environments using inertial navigation systems that don’t depend on external signals.
– Digital Cockpit: A modernized glass cockpit integrates multiple data streams into a streamlined display, reducing crew workload during the intense concentration required by low-level, high-threat flight.
– Enhanced Situational Awareness: Sensor fusion presents crews with a coherent tactical picture even when individual systems are degraded — which inside an A2/AD bubble is the expected operating condition, not an exception.
Secure Communications: Staying Connected Under Jamming
Coordinating a rescue mission requires constant communication — with the isolated survivor, with the supporting HC-130J tanker, with fighter escort, and with command authorities. Inside a sophisticated EW environment, maintaining that communication is far from guaranteed.
The HH-60W’s communications suite directly counters this threat through:
– Secure, Jam-Resistant Radio Systems: Frequency-hopping and encryption technologies make communications significantly harder to jam or intercept.
– Satellite Communications (SATCOM): Beyond-line-of-sight communication that doesn’t depend on line-of-sight radio propagation, allowing the crew to maintain contact with command even deep inside enemy territory.
– Interoperability: The ability to communicate across multiple platforms and services, coordinating the joint force elements that make a successful CSAR mission possible.
Weapons Systems: The Capacity for Self-Defense
CSAR helicopters have never been offensive platforms, but they must be able to fight their way in and out. The HH-60W carries flexible weapon systems including GAU-2 and GAU-18 machine guns for suppressive fire — providing crews with the means to engage ground threats during approach, recovery, and egress.
This capability is particularly relevant in A2/AD environments where the threat isn’t just from sophisticated missiles but from integrated ground forces protecting the area where an isolated survivor might be located.
All-Weather, Day/Night Operations
An adversary’s A2/AD bubble doesn’t respect weather or time of day — and neither can a rescue mission. The HH-60W is equipped with Forward-Looking Infrared (FLIR) sensors and advanced radar systems that enable it to operate effectively in darkness, rain, fog, and other adverse conditions that might otherwise force a rescue to wait.
In the critical hours following a shootdown, that all-weather, day/night capability can be the difference between a live recovery and a failed mission.
Operational Impact: Why A2/AD-Penetrating CSAR Matters Strategically
The operational value of the HH-60W extends well beyond the individual missions it will fly. Its very existence as a credible A2/AD-penetrating platform creates strategic effects that ripple outward in several directions.
Morale and Willingness to Engage: Every pilot who flies a strike mission into contested territory knows whether a capable rescue asset exists if they’re shot down. When that asset exists and is credible, commanders can order missions that might otherwise be deemed too risky. When it doesn’t, aircrew hesitation increases — rightly so — and operational options narrow.
Deterrence Value: A capable CSAR platform signals to adversaries that shooting down aircraft doesn’t automatically convert pilots into permanent prisoners or casualties. This partially negates one of the strategic calculus elements adversaries use when deciding whether to engage U.S. aircraft.
Power Projection: The ability to operate inside — not around — A2/AD bubbles fundamentally changes what military operations are possible in a high-threat environment. If rescue remains possible, operations can continue at tempo. If rescue is impossible, operational risk calculus changes dramatically.
Training for the Threat
The crews flying the HH-60W are trained extensively for high-threat, A2/AD-specific scenarios. Pararescuemen (PJs) — the highly trained special operations personnel who conduct the actual rescues — train alongside pilots for the specific physical and tactical demands of penetrating defended airspace. Mission rehearsal, threat recognition, and integration with electronic warfare assets all form core elements of the Jolly Green II mission package.
Challenges and the Road Ahead for the Jolly Green II
No honest assessment of the HH-60W program is complete without addressing the challenges it faces — because the gap between a capable platform on paper and a fully realized operational capability is real.
Procurement Questions
The program’s original requirement called for 113 aircraft. Reports have emerged suggesting that the Air Force has considered ending procurement earlier — potentially at 75 aircraft — citing cost concerns and questions about the platform’s suitability for the most demanding high-threat scenarios. At approximately $50 million per unit, with total program costs substantially higher when training, support, and integration expenses are included, budget pressure is real.
The concern isn’t primarily about the HH-60W’s capabilities relative to the HH-60G — it’s a clear and substantial improvement. The question is whether those improvements are sufficient to meet requirements against the most advanced A2/AD threats adversaries could field in a major conflict.
The Enduring A2/AD Challenge
Critics have raised a legitimate point: even with all of its advanced defensive systems, the HH-60W is still a relatively slow rotary-wing aircraft operating in an environment designed to kill much faster fixed-wing platforms. Against the most sophisticated A2/AD layering — think integrated S-400 systems combined with advanced EW and networked command nodes — the question of survivability remains an open and serious one.
The platform’s designers acknowledge this reality. The HH-60W is built to maximize survivability, not guarantee it. The response involves a combination of technology, tactics, and force integration — using suppression of enemy air defenses (SEAD) assets, electronic attack aircraft, and fighter escorts to degrade the A2/AD environment before and during a rescue attempt. The HH-60W is one element in a combined-arms approach, not a standalone solution.
Looking Forward
Future upgrades to the platform’s defensive systems, communications capabilities, and avionics are expected as threats evolve. The modular nature of the Integrated Mission System is specifically designed to accommodate block upgrades, allowing the aircraft to be updated without complete redesign. Whether the procurement and budget process will fully fund these upgrade paths remains a question the program continues to navigate.
Conclusion: The Jolly Green II’s Indispensable Role
Combat Search and Rescue in anti-access/area denial environments is one of the hardest problems in modern military aviation. The HH-60W Jolly Green II represents the most serious attempt to date to solve it — combining doubled fuel capacity, an Integrated Defensive System, jam-resistant communications, GPS-degraded navigation capability, and flexible weapons into a single purpose-built platform.
Its creation reflects a clear-eyed assessment that future conflicts will be fought inside threat envelopes that previous CSAR platforms simply couldn’t survive. Procurement challenges and enduring questions about high-end threat survivability are real, but they don’t change the fundamental requirement: service members will go down in contested territory, and the promise to recover them must remain credible.
The Jolly Green II carries both the legacy of its Vietnam-era namesakes and the burden of a far more complex threat environment. Whether it fully delivers on every aspect of that promise will depend on continued investment, rigorous training, and the integration of joint force assets that no single helicopter — no matter how capable — can replace on its own.

Frequently Asked Questions
What does the HH-60W Jolly Green II replace?
The HH-60W replaces the HH-60G Pave Hawk, which has served as the primary U.S. Air Force combat search and rescue helicopter since the 1980s. While the Pave Hawk performed effectively across multiple conflicts, its range, defensive systems, and avionics were not designed to handle the sophisticated A2/AD environments posed by modern near-peer adversaries.
How does the HH-60W differ from the HH-60G in terms of range?
The HH-60W features doubled internal fuel capacity compared to the HH-60G, significantly extending its operational radius without relying on external fuel tanks. Combined with aerial refueling capability from HC-130J tankers, this allows the Jolly Green II to reach isolated personnel at distances the Pave Hawk could not cover — a critical advantage in contested, long-range scenarios.
What is the Integrated Defensive System (IDS) on the HH-60W?
The IDS is a unified defensive suite that includes missile warning systems, radar warning receivers, and countermeasures dispensers (chaff and flares). Rather than a collection of individual bolt-on components, the IDS is deeply integrated into the aircraft’s systems, enabling automated threat responses and giving crews significantly better protection against SAM systems and MANPADS threats common in A2/AD environments.
How many HH-60W Jolly Green II helicopters is the Air Force acquiring?
The original program of record called for 113 aircraft. However, reports have indicated potential pressure to reduce that number, possibly to 75, due to cost concerns and ongoing debates about the platform’s suitability against the most advanced threat environments. The final procurement total continues to evolve as budget cycles and operational requirements are assessed.
Can the HH-60W operate in GPS-denied environments?
Yes. The HH-60W’s Integrated Mission System includes advanced precision navigation capabilities that incorporate inertial navigation systems, allowing the aircraft to operate effectively even when adversary electronic warfare has jammed or spoofed GPS signals — a realistic operational condition inside any sophisticated A2/AD bubble.
Where is the HH-60W Jolly Green II based operationally?
The first operational unit to receive the HH-60W is the 23rd Wing at Moody Air Force Base in Georgia. The 23rd Wing has a long history with CSAR operations and was the natural choice to stand up as the initial operational unit for the new platform.
