The Air Force Research Laboratory (AFRL) has issued a notice to the defense industry, signaling its intent to develop a new low-cost hypersonic cruise missile. This initiative aims to create a weapon capable of delivering a diverse range of payloads over distances up to 500 nautical miles.
The broad outlines of this new project were detailed in a concise, one-page notice released on September 1 via Sam.gov, the U.S. government’s official contracting portal. This effort falls under the AFRL’s broader “Pioneering Aerospace Capabilities, Engineering & Research” program.
The notice specifically encourages potential offerors to incorporate “modular open systems architectures, together with aggressive application of digital engineering advanced manufacturing techniques.” This directive suggests a strong interest in innovative production methods, such as 3D printing, as a means to achieve a significantly more affordable hypersonic missile compared to those currently under development by the Air Force.
This new initiative stands apart from the Air Force’s two other major hypersonic weapon programs: the Hypersonic Attack Cruise Missile (HACM) and the Air-Launched Rapid Response Weapon (ARRW).
HACM is an ongoing Air Force collaboration with RTX, focused on developing a scramjet-powered, air-breathing hypersonic missile. Designed to achieve and sustain speeds of Mach 5 or greater, HACM is intended for deployment from both tactical fighters and bombers, with Northrop Grumman responsible for its engine development.
Conversely, ARRW is a boost-glide, air-launched hypersonic weapon developed by Lockheed Martin, primarily designed for deployment from bomber aircraft.
Payload Flexibility
A key distinguishing feature of the new AFRL project is its “no specific payload requirement,” as stated in the notice. This agnostic approach contrasts with HACM, which was initially conceived around a kinetic warhead designed for striking heavily defended targets. The absence of specific warhead requirements for the new project opens possibilities for it to carry a range of payloads, including traditional kinetic strike options, intelligence, surveillance, and reconnaissance (ISR) equipment, or electronic warfare (EW) systems.
Despite the flexibility, the kinetic strike capability remains a significant consideration. Retired Air Force Col. Mark Gunzinger, director of future concepts and capability assessments at the Mitchell Institute for Aerospace Studies, highlighted the potential for such a weapon. He noted that it “could provide new ‘middle ground’ options for precision strikes against time-sensitive targets.”
Gunzinger further elaborated on its potential applications, suggesting that “depending on its seekers and warhead variants, a 500-nautical mile hypersonic weapon could be used against ground fixed and relocatable targets, moving maritime targets, and possibly even high-value airborne targets like [Airborne Early Warning & Control] aircraft.”
Expanded Operational Options
Such a weapon could significantly broaden the operational options available to Air Force planners, particularly in geographically expansive regions like the Pacific. In these areas, potential adversaries, such as the Chinese military, employ sophisticated anti-access/area-denial (A2/AD) systems designed to restrict military movements and operations.
Gunzinger underscored the critical role of hypersonic capabilities in overcoming many of the Chinese military’s advanced defenses. He stated, “The capability and capacity to conduct prompt maritime strikes against moving targets such as the [People’s Liberation Army Navy] Type 055 Renhai class cruisers and Type 52D Luyang-III class destroyers will be critical to defeating an assault on Taiwan or other scenario.” He also emphasized “the value of using hypersonic class weapons to counter high-value airborne aircraft like KJ-500/600 AEW&C aircraft, which will be key to countering the PLA Air Force’s long-range kill chains.”
If appropriately scaled, this type of missile could also be integrated across a wide array of aircraft platforms, including the F-15EX, B-21, B-2, and even fifth-generation fighters like the F-35, according to Gunzinger. He added, “Frankly, sixth-generation stealth aircraft will not need 500 [nautical mile] standoff, but it would increase their ability to avoid the highest risk threat areas and expand areas it can attack in a single sortie.”
While the Air Force continues efforts to field HACM, Gunzinger views the potential low-cost cruise missile as an additive capability rather than a replacement. He specifically highlighted its value if it could carry EW payloads, which are crucial for the suppression of enemy air defenses.
Scaling and Cost Efficiency
The emphasis on 3D printing and advanced manufacturing is intended to enable the Air Force to scale production of these weapons in a manner that experts like Gunzinger and the Mitchell Institute have long advocated. Affordability has historically presented a significant hurdle to fielding hypersonic weapons at scale.
Gunzinger provided context, stating, “Affordability can be a barrier to fielding hypersonic weapons at scale—the Army’s ‘Dark Eagle’ ground-launched boost-glide weapon that costs $40 million or more for a single warhead is a good example of this.” He concluded that “an air-launched weapon that costs low single-digit millions of dollars each would increase the potential to acquire them at scale.”
For its current fiscal year 2027 budget request, which is undergoing Congressional review, the Air Force is seeking $1.96 billion in hypersonic funding for both HACM and ARRW.
Approximately $1.2 billion of this request is allocated for HACM, with $404 million designated for purchasing the initial operational lot of missiles and an additional $806 million for continued research, development, test, and evaluation activities.
For ARRW, the service is requesting approximately $748 million. This includes $452 million for procurement and $296 million for an Increment 2 version of the weapon, intended for adaptation to long-range counter-maritime missions.
Beyond hypersonics, the Air Force has shown a broader commitment to developing more affordable munitions. This is evident in its Family of Affordable Mass Munitions (FAMM) program, which aims to field 28,000 low-cost cruise missiles over the next five years. In July, the Pentagon announced multiyear contracts with companies Anduril, CoAspire, and Zone 5 Technologies to accelerate the production of these non-hypersonic weapons, with initial deliveries projected for 2027.
Project Development Process
The development of the affordable hypersonic missile project will proceed in two distinct phases. The initial phase will involve AFRL accepting white paper submissions from interested industry partners. Following a review of these submissions, a second phase will invite selected companies to submit full technical and cost proposals.
According to Molly Lachance, an AFRL spokesperson, the lab first posted a notice for a potential “focused call” or technology demonstration competition in January, titled “Rapid Maturation and Demonstration of Hypersonic Weapon Concepts.” This was followed by a call for “Hypersonic Affordable Mass Weapon Concepts” (HAMWC) on March 16.
Lachance explained the recent resolicitation, stating, “Following internal reviews and refined program requirements for the Hypersonic Affordable Mass Weapon Concepts (HAMWC) effort, we updated key project parameters to better align with mission priorities. Because these adjustments represented a material change to the original scope, a resolicitation was required.”
For the latest September 1 notice, AFRL anticipates posting further amendments within 30 days.
Why This Matters
The Air Force Research Laboratory’s pursuit of a low-cost, multi-payload hypersonic cruise missile represents a significant shift in U.S. defense strategy and procurement, with far-reaching implications across several domains.
**Strategic Adaptation and Deterrence:** This initiative signals a clear response to the evolving global security landscape, particularly the advancements made by peer competitors in hypersonic technology and anti-access/area-denial (A2/AD) capabilities. By developing more affordable and rapidly deployable hypersonic weapons, the U.S. aims to restore a credible deterrent, ensuring its ability to strike time-sensitive, highly defended targets without committing larger, more expensive assets to high-threat environments. The 500-nautical-mile range and multi-platform compatibility enhance tactical flexibility, offering more options for commanders in contested regions, especially the Indo-Pacific.
**Technological Innovation and Industrial Base:** The emphasis on “modular open systems architectures,” “digital engineering,” and “advanced manufacturing techniques” like 3D printing is transformative. This approach seeks to revolutionize the defense industrial base by fostering innovation, accelerating development cycles, and driving down per-unit costs. A successful implementation could pave the way for a new era of defense acquisition, where advanced weapons are not only cutting-edge but also affordable enough to be produced at scale, a critical factor for sustained operational effectiveness in potential long-duration conflicts.
**Economic Efficiency and Resource Allocation:** The current high cost of existing hypersonic programs (e.g., the Army’s “Dark Eagle” at over $40 million per warhead) presents a barrier to large-scale deployment. A low-cost alternative, potentially in the “low single-digit millions,” could fundamentally alter defense budgeting. It would allow the Air Force to procure a larger inventory of these advanced weapons for the same investment, improving readiness and operational capacity. This focus on affordability also reflects a broader Pentagon effort, exemplified by the Family of Affordable Mass Munitions (FAMM) program, to develop cheaper, mass-producible armaments across the board.
**Operational Flexibility and Multi-Domain Capability:** The project’s “payload agnostic” design is a game-changer. Unlike dedicated kinetic strike weapons, this new missile could carry a variety of payloads, including kinetic warheads, intelligence, surveillance, and reconnaissance (ISR) sensors, or electronic warfare (EW) systems. This versatility means a single weapon system could perform multiple roles, from precision strike to battlefield awareness or even suppressing enemy air defenses, thereby maximizing the return on investment and enhancing the adaptability of air assets in complex operational scenarios.
In essence, this AFRL initiative is not merely about building another weapon; it represents a strategic pivot towards a more agile, cost-effective, and adaptable defense posture, crucial for maintaining a technological edge and deterring aggression in an increasingly complex global environment.
