IAI's HYPNOSIS and PAC-3 ACE Landed Days Apart. The Gap Between Them Is Where European EW Founders Should Be Building.

In the days bracketing the opening of Farnborough International Airshow 2026, two announcements described the same strategic problem from opposite ends: Western air defence is spending too much money to shoot down cheap things. The responses could not be more different in their implications for the European defence-tech ecosystem.

Lockheed Martin announced the PAC-3 Adapted Capability Effector, or PAC-3 ACE, on 20 July 2026 at Farnborough: a low-cost interceptor built to defeat a wide range of air and missile threats for less than half the cost of a PAC-3 MSE per unit investors.lockheedmartin.com. Four days earlier, on Thursday 16 July, Israel Aerospace Industries unveiled HYPNOSIS, a High-Power Soft-Kill Navigation Warfare Air Defense System designed to disrupt GPS and GNSS satellite navigation signals used by aircraft and drone swarms edrmagazine.eu.

The Farnborough context matters. The announcement came as the U.S. looks to reduce dependence on expensive interceptors to combat mass-produced munitions, a juxtaposition that has attracted increased scrutiny as American forces have burned through their finite interceptor stockpile countering Iran's relatively inexpensive drones defensenews.com. Defense News reports PAC-3 interceptors cost an estimated $4 million, far more than the $35,000 typical price tag of an Iranian Shahed drone defensenews.com. U.S. Army FY2026 procurement documents put the flyaway unit cost of the PAC-3 MSE at $3.871 million, comprising $3.331 million for the missile itself plus ancillary equipment and a producibility resilience allowance asafm.army.mil. HYPNOSIS tries to sidestep that cost trap entirely.

What HYPNOSIS Actually Is

IAI unveiled HYPNOSIS as a navigation warfare system designed to counter one of the more stubborn problems facing modern air defence: how to stop large volumes of drones and other GNSS-guided threats without relying solely on missiles to shoot them down edrmagazine.eu. Rather than intercepting incoming threats directly, the system attacks the satellite signals those threats depend on to find their way.

HYPNOSIS comprises an array of mobile jamming and spoofing stations that operate in unison to create a comprehensive, adaptive solution. Each station is connected to a central Command and Control centre, enabling real-time coordination, threat analysis, and rapid response 2 sources. The system can counter coordinated attacks involving multiple threats approaching simultaneously from different directions, while supporting fully autonomous operation through its networked C2 centre without the need for operator intervention 2 sources.

HYPNOSIS attacks GNSS dependency using two related but distinct techniques. Jamming works by overpowering the legitimate satellite signal with a stronger radio transmission on the same frequency, effectively drowning out the real navigation data a drone needs to receive. Spoofing goes further: it broadcasts fake navigation signals that send a weapon off course without the drone registering that its guidance has been compromised 2 sources.

For Guy Barlev, Executive Vice President and General Manager of IAI's Space Missiles and Systems division, the case for HYPNOSIS rests on what it adds to defences that already exist. He was explicit that the system is designed to work alongside, not instead of, traditional missile defences: "When integrated with hard-kill defense systems, it further strengthens the multi-layered defense concept by adding an additional protection layer that is operationally effective and cost-efficient complementing existing kinetic interception systems" defensenews.com.

The timing of the announcement, two days before Farnborough opened on 20 July, was deliberate: it arrives against a backdrop of documented GNSS interference already endangering civil aviation worldwide techtimes.com. IAI markets primarily to sovereign customers, and the Farnborough window concentrates exactly that audience.

The Limits of a GNSS-Only Soft-Kill Layer

HYPNOSIS is a commercially coherent product. It is not a complete answer to the drone swarm problem, and the public record is clear about why.

The Shahed-136 drones that have driven the Patriot interceptor cost crisis carry both GNSS and an inertial navigation system as backup. An INS uses onboard gyroscopes and accelerometers for dead-reckoning, continuously estimating position from a known starting point without any external signal. A drone whose GNSS is successfully jammed can, in principle, continue navigating via INS, with accuracy degrading over distance depending on the quality of the inertial sensors. The degree to which HYPNOSIS defeats INS-equipped drones is not addressed in IAI's public materials 2 sources. Beyond INS, more advanced drones are being developed with optical navigation using terrain-reference imagery and lidar, systems that are fully independent of any satellite signal.

There is also a documented civilian spillover risk that any NAVWAR deployment will have to reckon with. According to IATA's data from the Global Aviation Data Management Flight Data eXchange, GPS signal loss events increased by 220% between 2021 and 2024 iata.org. A joint EASA-IATA workshop concluded that a broader and more coordinated approach is needed, given the continued rise in frequency of incidents of interference with GNSS signals, which have been increasing across Eastern Europe and the Middle East in recent years easa.europa.eu.

The consequences have been concrete. The loss of Azerbaijan Airlines flight 8243, an Embraer E190, on 25 December 2024 raises troubling questions about air defence command and control. The aircraft departed Baku bound for Grozny International Airport; at around 08:20 local time the crew reported the loss of GPS position data, and the aircraft subsequently crashed near Aktau International Airport on Kazakhstan's Caspian Sea coast 2 sources. The interference was attributed to Russian GNSS jamming over Grozny and its environs. Russian authorities acknowledged that GNSS jamming was being performed at the time to protect the city against Ukrainian drone attack 2 sources.

Sources revealed to Euronews that electronic warfare systems were deployed against the Azerbaijani aircraft as it approached Grozny, followed by a strike from a Russian Pantsir-S1 air defence system euronews.com. A preliminary report issued on 4 February 2025 by Kazakhstan's Ministry of Transport stated that the aircraft likely crashed due to the penetration of external objects into its structure, with the report detailing extensive damage to the fuselage and vertical stabiliser consistent with high-velocity fragments euronews.com. The full formal investigation was still ongoing as of mid-2026. The causal sequence involving GNSS jamming and subsequent engagement remains subject to the investigation's final conclusions, and should be read as preliminary findings, not established fact.

EASA Flight Standards Director Jesper Rasmussen stated: "GNSS disruptions are evolving in terms of both frequency and complexity. We are no longer just containing GNSS interference, we must build resilience. The evolving nature of the threat demands a dynamic and ambitious action plan" easa.europa.eu.

For any company selling high-power GNSS jamming and spoofing equipment near civil aviation corridors in Europe, this regulatory posture is a live constraint, not background noise.

What This Means for the European EW and C-UAS Market

IAI's system is an Israeli product aimed at sovereign buyers. But the problem it addresses and the architecture it represents are directly relevant to what European defence-tech founders are building.

The core procurement signal is layered architecture. HYPNOSIS is positioned as a method for taking out large numbers of drones at once, in situations where hard-kill intercepts would be tricky to execute because of the number of airborne objects techtimes.com. European MoDs are internalising exactly this lesson. The demand is not for one system that defeats everything: it is for a stack of complementary capabilities, each addressing a different threat profile at a different cost point.

That stack has visible seams. HYPNOSIS addresses GNSS-primary threats. It does not, by IAI's own public framing, resolve INS-equipped or optically-guided threats. Radar-based detection and classification sit upstream of any EW or kinetic response. Networked C2 connecting EW nodes to hard-kill systems is itself a product category. Integration between legacy Patriot-class systems and new soft-kill layers requires interoperability engineering. Each of these gaps is an addressable problem.

European defence investment is moving fast, but capital is concentrating. A joint report by Dealroom and the NATO Innovation Fund shows that European defence, security, and resilience startups secured a record $8.7 billion in venture capital in 2025, up 55% year on year and nearly four times higher than five years ago businesswire.com. EW and NAVWAR are not yet a dominant share of that flow, but procurement pressure for GNSS soft-kill from European MoDs will shift the calculus.

The political dimension matters too. Lockheed Martin plans to develop and manufacture PAC-3 ACE jointly with American and European industry partners, an approach intended to strengthen the broader defence industrial base on both sides of the Atlantic 2 sources. That commercial logic runs in parallel with a political one: European governments have a stated preference for non-U.S., non-Israeli supply chains where capability equivalence can be demonstrated. That tension is a structural opening for European-sovereign EW ventures.

For Founders

If you are building in EW or NAVWAR: HYPNOSIS is not your competition. It is market validation from a credible prime. IAI has now publicly demonstrated that a system designed to simultaneously disrupt and neutralise multiple aerial threats that rely on GNSS is a procurable product category, not a research concept 2 sources. Your question is where in the stack you sit and whether you can reach hardware-demonstrated performance fast enough to enter RFI cycles that European MoDs will now run.

The joint EASA-IATA workshop concluded that a broader and more coordinated approach is needed, focusing on four key areas: improved information gathering, stronger prevention and mitigation measures, more effective use of infrastructure and airspace management, and enhanced coordination and preparedness among relevant agencies easa.europa.eu. Any deployment near civil airspace will require a credible deconfliction answer. Build that technical and regulatory answer before procurement asks for it, because they will. In practice that means demonstrating how your system avoids contaminating adjacent civil corridors: directional beam control limits transmissions to a defined angular sector rather than radiating in all directions; geofencing applies system-level rules that prevent activation within defined proximity to civil flight paths.

If you are building GNSS-resilience or anti-jam for friendly assets: the same regulatory pressure that constrains offensive NAVWAR deployment creates mandatory demand for anti-spoofing on the defensive side. IATA's data shows GPS signal loss events increased 220% between 2021 and 2024, and with continued geopolitical tensions it is difficult to see this trend reversing in the near term iata.org. Companies that can demonstrate GNSS-resilient positioning, navigation, and timing for UAVs, logistics platforms, or critical infrastructure in EASA-compliant form have a route that bypasses some of the export-control and classification friction that pure military EW faces.

If you are building C-UAS detection and classification: the commercial reality of soft-kill layers is that they need good upstream detection to know which threats are GNSS-primary and which are not. HYPNOSIS is built specifically to handle coordinated attacks in which multiple threats approach simultaneously from different directions, and is designed to run autonomously through its networked command centre without requiring an operator to intervene 2 sources. Autonomous EW response at machine speed requires upstream sensor and classification data that the EW layer does not generate itself. That data layer is your insertion point into the same procurement stack.

On the cost-asymmetry framing broadly: both announcements confirm that Western procurement is now explicitly optimising for cost-per-engagement reduction. Lockheed Martin said PAC-3 ACE is meant to reduce cost-per-kill 2 sources, and the programme will be built collaboratively with American and European industry partners and suppliers, fully linked to the Patriot weapon system and the Integrated Battle Command System 2 sources. If primes are repricing kinetic interceptors to compete on cost, the unit economics argument for EW and soft-kill alternatives becomes more compelling in MoD procurement conversations, not less. Frame your proposition in those terms: not just capability, but cost per neutralised threat, and what that number looks like at swarm scale.
