This article is based on an official press release from General Atomics Aeronautical Systems, Inc. (GA-ASI), supplemented by industry research.

We report on the latest developments in the U.S. Air Force’s Collaborative Combat Aircraft (CCA) program. According to an official press release from General Atomics Aeronautical Systems, Inc. (GA-ASI), the company successfully completed a joint autonomy flight exercise with the USAF on February 24, 2026. The milestone, publicly announced on March 17, 2026, utilized an MQ-20 Avenger® uncrewed jet acting as a surrogate testbed for the CCA initiative.

The core achievement of this demonstration was the aircraft’s ability to execute passive target localization. By relying on Infrared (IR) sensing and Single Ship Ranging (SSR) rather than traditional active radar, the uncrewed jet estimated target ranges and tracked airborne threats without emitting detectable electromagnetic signals.

As we track the evolution of uncrewed military aviation, this capability represents a significant leap forward. It enables what defense experts call “stealthy sensor-to-shooter kill chains,” allowing autonomous wingmen to operate effectively in highly contested, radar-denied environments alongside crewed fighters.

The Silent Wingman: Mastering Passive Targeting

In modern air combat, emitting an active radar signal is often compared to turning on a flashlight in a dark room, it illuminates the target but immediately reveals the user’s position to adversaries. According to the GA-ASI press release, the February 24 exercise demonstrated a viable, stealthy alternative.

Integrating TacACE and SSR

The MQ-20 Avenger utilized a combination of the government-provided Autonomy Start Kit (ASK) and GA-ASI’s proprietary Tactical Autonomy Ecosystem (TacACE®). The integration of Infrared Search and Track (IRST) sensors alongside SSR techniques allowed the aircraft to track targets using heat signatures. The engagement sequences were managed via a TacPad Pilot Vehicle Interface (PVI), while a Proliferated Low-Earth Orbit (pLEO) data link ensured seamless communication and coordination of autonomy behaviors during the large force exercise.

“Integrated within the TacACE’s modular skills library, SSR supports autonomous mission execution, cooperative targeting, and distributed kill chains, advancing the role of autonomous aircraft in future air combat and CCA operations,” stated Mike Atwood, Vice President of Advanced Programs for GA-ASI, in the company’s release.

The Broader Collaborative Combat Aircraft (CCA) Race

The CCA program is a multi-pronged initiative by the U.S. Air Force designed to field a new generation of highly autonomous, lower-cost uncrewed jets. Industry research notes that these aircraft are intended to fly alongside crewed fifth- and sixth-generation fighters, such as the F-35 and F-22, providing “affordable mass” to multiply combat power while reducing risks to human pilots.

Timeline and Production

GA-ASI is currently one of two primary vendors, alongside Anduril Industries, competing for the Increment 1 production contract of the CCA program. The Air Force is expected to select a final winner for both the physical aircraft design and the mission autonomy software by the end of 2026.

“We’ll be making that decision [on the Increment 1 winner] by the end of the year… That will happen this year and then we’ll get moving pretty darn quickly on production,” noted Col. Timothy Helfrich, USAF Portfolio Acquisition Executive for Fighters and Advanced Aircraft, speaking at the AFA Warfare Symposium in February 2026.

Recent Milestones for the “Dark Merlin”

While the MQ-20 Avenger has served as a reliable surrogate testbed for over five years, GA-ASI’s official, purpose-built CCA prototype is the YFQ-42A. According to recent industry reports, the company officially nicknamed the aircraft the “Dark Merlin” in February 2026, following its maiden flight in August 2025. The aircraft is designed specifically for rapid, low-cost production.

Open Architecture and Marine Corps Expansion

The pace of development has accelerated rapidly in early 2026. On February 12, 2026, the USAF and GA-ASI successfully flew the YFQ-42A using third-party mission autonomy software, specifically, Collins Aerospace’s “Sidekick.” This flight proved the viability of the military’s Autonomy Government Reference Architecture (A-GRA), demonstrating that the Air Force can successfully decouple physical aircraft hardware from the Software brains that pilot it.

Furthermore, the CCA concept is expanding beyond the Air Force. On February 10, 2026, the U.S. Marine Corps selected GA-ASI for its MUX TACAIR program. The Marines are using the YFQ-42A as a surrogate to evaluate how uncrewed collaborative aircraft can support expeditionary Marine Air-Ground Task Force operations.

AirPro News analysis

We view the shift toward passive IR sensing as a defining characteristic of the next generation of air combat. The ability of uncrewed systems to operate as “silent wingmen” fundamentally changes the tactical geometry of an engagement. By relying on heat signatures and single-ship ranging rather than active Radar-Systems, these platforms can survive longer in contested airspace, acting as forward sensor nodes that feed targeting data back to crewed fighters without exposing the broader formation. Additionally, the successful integration of third-party software via open architecture suggests that the Department of Defense is successfully breaking vendor lock, paving the way for rapid, iterative software updates akin to the commercial tech sector.

Scott Sims, H-1 program director at Bell, emphasized the importance of the milestone in the official release:

“To have these first two aircraft completed under the SPINE program is a huge moment for us,” said Sims. “At Bell, crew safety and aircraft effectiveness remain the number one priority on everything we do. These upgrades will ensure that our H-1 aircraft remain the most capable aircraft available, while operating at the forefront of modern missions. They will continue to excel at the job they were designed to do for many years to come.”

Future-Proofing the USMC H-1 Fleet

Testing and Deployment Strategy

The AH-1Z Viper, a dedicated attack helicopter, and the UH-1Y Venom, a versatile utility helicopter, share a high degree of component commonality despite their different battlefield roles. According to supplementary industry data, the USMC’s program of record includes 349 H-1 aircraft. The H-1 family has a storied legacy, with modern variants surpassing 400,000 joint-flight hours since 2010.

The current flight tests at NAS Patuxent River are critical for validating the recent upgrades. Data gathered during this phase will determine the final, standardized SPINE configuration. Once approved by the U.S. government, Bell plans to roll out these modifications to the broader USMC fleet over the next decade through future contracted efforts.

Danielle Markham, program manager at Bell, noted the operational necessity of the upgrades:

“In the competitive world that the H-1 lives and thrives in, it’s vital to remain competitive with current and future capabilities and to excel in every environment where these aircraft are deployed,” Markham stated in the press release. “The SPINE program represents the next step in the H-1 evolution, ensuring the platform has structural strength, electrical capacity, and digital foundation needed to operate as a fully interoperable member of the modern joint force.”

On March 16, 2026, Elbit Systems of America announced it had secured a $49.9 million contract from the U.S. Army. According to the company’s official press release, the award funds the production of colorized Heads-Up Displays (HUDs), specifically the Air Warrior HUD, for integration into the Army’s UH-60 Black Hawk and CH-47 Chinook Helicopters. The technology serves as a critical component of the military’s broader Air Soldier System, which is designed to maximize aircrew survivability and situational awareness.

The Firm-Fixed-Price, Indefinite-Delivery/Indefinite-Quantity (IDIQ) contract was awarded by the U.S. Army Contracting Command, located at Redstone Arsenal, Alabama. Elbit Systems of America, headquartered in Fort Worth, Texas, stated that work and post-production support will be carried out through December 2030, subject to the receipt of specific purchase orders from the military.

Modernizing Army Aviation with Colorized HUDs

The “Head-Up, Eyes-Out” Advantage

In modern combat aviation, the ability to process information without looking down at dashboard instruments is a critical survival factor. The newly contracted Air Warrior HUD projects essential flight, navigation, and mission data directly into the pilot’s line of sight. According to the manufacturer, this allows the aircrew to remain “head-up and eyes-out,” maintaining constant visual contact with their external surroundings. This capability is particularly vital during low-altitude flights or in degraded visual environments where spatial awareness is easily compromised.

Furthermore, the transition from legacy monochrome displays to modern colorized HUDs represents a significant technological leap. Colorized data significantly accelerates a pilot’s ability to process complex information, allowing them to more rapidly differentiate between friendly and enemy symbology and react to emerging threats.

“The Air Warrior Heads Up Display allows aircrew to focus on the mission because it’s designed to ensure safety, efficiency, and comfort,”

said Scott Tumpak, Senior Vice President of Electronic Systems at Elbit America, in the company’s press release.

The Evolution of the Air Soldier System

Reducing the Physical Burden on Pilots

The Air Warrior HUD is a sub-component of the U.S. Army’s overarching Air Soldier System. Historically, Army aviators relied on the original “Air Warrior” ensemble, which was first fielded around 2004. While effective for its time, historical data from U.S. Army Official Archives notes that the legacy gear was notoriously heavy and bulky, contributing to pilot fatigue during extended missions.

The modern Air Soldier System was developed specifically to address these ergonomic challenges. By integrating highly advanced, lightweight wearable electronics and displays, the updated system reduces the physical weight burden on pilots by up to 40%. The current displays are operational on two of the military’s most heavily utilized rotorcraft: the UH-60 Black Hawk utility helicopter and the CH-47 Chinook heavy-lift helicopter.

“Elbit America delivers combat-proven Heads Up Displays that provide aircrew the confidence to see first, act first, and win,”

noted Luke Savoie, President and CEO of Elbit America, emphasizing the operational impact of the technology.
