Air combat is racing toward a tipping point where speed, data and exotic physics matter more than radar cross section alone. Seventh generation fighters, hypersonic strike weapons and quantum-enabled sensing are converging into a battlespace that could make today’s stealth jets look like analog relics. The same technologies that promise unprecedented reach and precision are also eroding the very invisibility that defined airpower for a generation.
I see three intertwined revolutions driving this shift: aircraft that blend autonomy with extreme speed, missiles that compress decision time to seconds and quantum tools that can both expose and protect forces in ways classic radar never could. Together they are forcing militaries to rethink what “survivability” means after stealth.
The contested future of stealth
For decades, low observable design has been treated as the entry ticket to high-end air warfare, yet senior technologists are now openly questioning how long that advantage can last. Rob McHenry, the Deputy Director of the Defense Advanced Research Projects Agency, has argued that the combination of proliferating sensors and advanced processing risks making traditional stealth an “attractive but elusive technology,” a warning that reflects DARPA concern that survivability must be redefined. Analysts describing an emerging “electromagnetic armageddon” argue that dense networks of emitters and receivers, spread across land, sea, air and space, are beginning to close the gaps that once allowed aircraft like the F-35 to hide effectively, a trend captured in detailed Key Points and on how modern radars are eroding low observability.
At the same time, other defense experts caution against declaring stealth dead, noting that each new detection technique must still be integrated into a kill chain that can track, target and engage fast-moving aircraft. Research that surveys emerging radar and computing technique concludes that while new systems will complicate operations, Stealth will likely remain a core Air Force tool for decades to come, a view captured in analysis that notes Stealth has survived multiple predicted demises and that, But for all the hype, it still underpins U.S. airpower today. The result is not a clean obituary for stealth but a transition toward platforms that treat low observability as one ingredient among many, rather than the whole recipe.
Seventh generation fighters: speed, autonomy and space
Seventh generation concepts build directly on that shift, treating survivability as a system-of-systems problem that fuses speed, autonomy and multi-spectral management. Reporting on future designs describes seventh generation fighters as autonomous, hypersonic, multi-spectral stealth platforms able to coordinate swarms of sensors and shooters, a vision that would make the F-35 look obsolete by comparison and could reshape air warfare for decades, as highlighted in recent analysis. Another detailed explainer on the next leap in air power emphasizes that the seventh generation fighter explained properly is less a single jet than a node in a wider combat cloud, with the next leap in air power expected to make today’s jets obsolete and set the tone for power projection for decades to come, a perspective captured in Jet Insight coverage that underscores how software and networking will matter as much as airframes.
Some visions go even further, sketching a hypersonic, space-traveling 7th generation stealth fighter that could operate in near-space regimes and carry directed energy weapons. One such concept, described as potentially flying by 2050, links the rise of the U.S. Space Force and the necessary task of preparing the U.S. military for offensive and defensive operations against intercontinental ballistic missiles or even hypersonic weapons, a connection drawn explicitly in a forward-looking assessment that notes, “This of course has inspired the creation of a US Space Force and the” broader shift to orbital defense. Even nearer term, discussions of a 47 designated next generation fighter suggest that an Air Force Chief Confirms an F-47 Next Generation Fighter Jet First Flight in 2028, a detail circulating in community discussions that, while not yet officially corroborated elsewhere, reflects how quickly planning is moving toward a post-sixth-generation era.
Hypersonic strike and the shrinking decision window
While airframes evolve, the most disruptive change may come from weapons that travel at hypersonic speeds and maneuver unpredictably. The United States has already reached a major hypersonic weapon milestone with a new long-range system, a development framed as historic in the contested race for such capabilities and described as a moment when The United States signaled it does not intend to sit out of this arms race, according to detailed reporting on a recent test. Parallel work on Conventional Prompt Strike, or CPS, aims to deliver non-nuclear effects at ranges comparable to intercontinental ballistic missiles, with assessments noting that CPS offers capabilities comparable to nuclear intercontinental ballistic missiles while employing conventional warheads, and that the U.S. Army’s LRHW is part of a broader portfolio whose effectiveness will take time to fully assess, as outlined in an overview of current programs.
Industry is racing to keep pace, with a recent Press Release describing how GE Aerospace and Lockheed Martin Demonstrate Rotating Detonation Ramjet for Hypersonic Missiles, a propulsion breakthrough that could make future weapons smaller, faster and more efficient, as detailed in hypersonic updates. Naval forces are adapting too, with Capt. Trinque stressing that “We have to continue building not just better missiles, but finding better ways to use our vertical launchers,” as the Navy explores a new missile that could serve both air defense and be a hypersonic strike weapon, according to naval reporting that underscores how ship magazines are being reimagined. Analysts tracking global developments note that hypersonic missiles are able to travel at extraordinary speeds and maneuver unpredictably, compressing reaction time and demanding decisive action on the battlefield, a dynamic highlighted in a recent update that also points to the role of systems like the Patriot defense system provided by the United States.
Quantum war: sensing, targeting and the end of hiding
Quantum technologies are emerging as the wild card that could finally tip the balance against stealth, even as they create new forms of protection and attack. Strategic assessments of Quantum Sensing and the Future of Warfare argue that Quantum’s Military Promise lies in sensors that will keep pushing the limits of detection, generating new radar and LiDAR signatures that can spot objects conventional systems miss, a prospect laid out in a set of Five Essential Reforms to Stay Competitive that warns Western forces must adapt quickly to quantum sensors. A separate analysis notes that since the Chinese Politburo’s study session in 2020 on quantum science, quantum references increased from 2% of Chinese science and technology planning documents to a much higher share, and that Quantum sensing will enable precise detection and targeting that could ravage millions of innocent people if misused, a sobering warning in a broader discussion of how the quantization of warfare is reshaping strategy and ethics in conflict.
Concrete hardware is already appearing. Chinese sources describe a photon catcher built by the Quantum Information Engineering Technology Research Center in Anhui province, characterized as an ultra-low noise, single-photon detector with four channels that can detect even a single particle of light, a device that Beijing claims as the “world’s first” and that could underpin quantum radars to track advanced stealth fighters like the F-22 Raptor jet, according to detailed reporting that also notes Advanced jets with enhanced capabilities The US Navy has already started working on the jet. Another account explains how a Chinese quantum radar sends pairs of entangled photons toward a target area and, Upon reflection, measures the returning photons to infer the presence of stealth aircraft, a method that, if operationalized at scale, could dramatically reduce the effectiveness of classic low observable shaping, as described in technical summaries of the system. Analysts like Bharat Karnad argue that It ( quantum technology ) is not happening anytime soon but Quantum technology will mark the end of stealth aircraft too, linking this to broader trends in Cyberwar and more, a perspective laid out in a call to speed up the hypersonic to the FOBS regime that frames quantum as the eventual stealth killer over time.
