Airbus Bird of Prey Drone Completes First Demo Flight in Germany
Airbus and Frankenburg Technologies demonstrate reusable Bird of Prey drone intercepting kamikaze drones with lightweight Mark I missiles in Germany.
This article is based on an official press release from Airbus.
Airbus Defence and Space has successfully conducted the maiden demonstration flight of its “Bird of Prey” uncrewed interceptor drone. According to a March 30, 2026, press release from the company, the test took place at a military training area in northern Germany, marking a significant milestone in counter-drone technology.
During a realistic mission scenario, the system autonomously searched for, detected, classified, and engaged a simulated medium-sized, one-way attack (kamikaze) drone. The successful interception was achieved using the newly integrated Mark I air-to-air missile, a lightweight weapon developed by Estonian defense tech startup Frankenburg Technologies.
This development highlights a rapid industry pivot toward cost-effective air defense solutions. As noted in the official announcement, the project moved from concept to flight in just nine months. The joint effort aims to provide armed forces with a reusable, highly mobile defense system capable of countering mass aerial threats at a sustainable cost.
The Bird of Prey is built upon a modified Airbus Do-DT25, a jet-powered aerial target drone originally developed in the early 2000s. According to the Airbus press release, the prototype features a wingspan of 2.5 meters, a length of 3.1 meters, and a maximum take-off weight of 160 kilograms. Supplementary industry data indicates that the underlying Do-DT25 platform can reach maximum speeds of 300 knots (555 km/h).
While the prototype carried four Mark I missiles during the recent test, Airbus states that the final operational version will be capable of carrying up to eight interceptors. Crucially, the platform is reusable; unlike traditional interceptors or kamikaze drones, the Bird of Prey fires its payload and returns to base. This design choice significantly reduces platform replacement costs and allows for multiple engagements per mission.
The Mark I missile, provided by Frankenburg Technologies, is billed as the lightest guided interceptor developed to date. The Airbus release notes it weighs less than 2 kilograms and measures 65 centimeters in length. Additional technical specifications from industry research reveal a 60-millimeter diameter, a solid-fuel rocket motor, and an electro-optical seeker equipped with both day and low-light capabilities.
The high-subsonic, fire-and-forget missile has an engagement range of up to 1.5 kilometers and can reach altitudes of 1,500 meters. It utilizes a 0.5-kilogram high-explosive fragmentation warhead paired with a proximity fuze, allowing it to neutralize targets at close range without requiring a direct hit. Frankenburg Technologies aims to offer the Mark I at roughly one-tenth the price of traditional short-range air defense (SHORAD) missiles. The proliferation of low-cost, one-way attack drones, such as those utilized extensively in recent Eastern European conflicts, has fundamentally altered modern air defense economics. Western militaries frequently rely on scarce, high-end surface-to-air missiles to neutralize cheap drones. For context, industry estimates place the cost of a conventional FIM-92 Stinger interceptor at approximately $500,000 per unit, creating an unsustainable economic imbalance when defending against drones that cost only a few thousand dollars.
“Against the current geopolitical and military backdrop, defending against kamikaze drones is a tactical priority that urgently needs to be tackled,” said Mike Schoellhorn, CEO of Airbus Defence and Space, in the company’s press release.
Frankenburg Technologies, founded in 2024 by Estonian entrepreneurs Taavi Madiberk and Marko Virkebau, aims to drastically lower the cost curve for air defense. The company is led by CEO Kusti Salm, former Permanent Secretary of the Estonian Ministry of Defence. According to recent financial reports, Frankenburg raised €30 million in February 2026 to establish two mass-production sites within the European Union, with an ambitious goal of producing over 100 missiles per day at each facility.
“This is a defining step for modern air defence,” stated Kusti Salm. “Together with Airbus, it marks the first integration of a new class of low-cost, mass-manufacturable interceptor missiles onto a drone, creating a new cost curve for air defence.”
To ensure seamless operation within NATO’s integrated air defense architecture, the Bird of Prey is designed to operate through Airbus’ Integrated Battle Management System (IBMS). The company notes that this integration allows the counter-UAS solution to act as a highly mobile, complementary building block within layered defense grids, multiplying the force effectiveness of existing radar and command nodes.
We observe that the rapid nine-month development cycle of the Bird of Prey, initially teased by Airbus in March 2025 under the moniker “LOAD” (Low-cost Air Defence), reflects a growing urgency within the European defense sector. By combining an existing, proven target drone airframe with a newly developed, mass-manufacturable micro-missile, Airbus and Frankenburg are bypassing traditionally sluggish defense procurement timelines. If the planned 2026 live-warhead tests succeed and Frankenburg meets its aggressive production targets, this system could offer a viable, scalable answer to the drone swarm tactics currently dominating asymmetric conflict theaters.
What is the Airbus Bird of Prey?
It is a reusable, uncrewed interceptor drone designed to autonomously detect, classify, and neutralize kamikaze drones using low-cost micro-missiles.
What missile does the Bird of Prey use?
It uses the Mark I air-to-air missile, a lightweight, high-subsonic interceptor developed by Estonian defense tech startup Frankenburg Technologies. How much does the Mark I missile weigh?
According to Airbus, the Mark I weighs less than 2 kilograms and measures 65 centimeters in length, making it the lightest guided interceptor developed to date.
When will the system be operational?
Airbus and Frankenburg plan to conduct additional test flights utilizing live warheads throughout the remainder of 2026 to fully operationalize the system and demonstrate its capabilities to potential buyers.

Russian An-26 Military Transport Crashes in Crimea Killing 29
A Russian An-26 military transport crashed in Crimea on March 31, 2026, killing all 29 on board due to a technical malfunction, officials say.
This article summarizes reporting by Reuters.
A Russian Antonov An-26 military transport aircraft crashed in the Crimean Peninsula on Tuesday, March 31, 2026, resulting in the deaths of all 29 individuals on board. According to reporting by Reuters, which cited Russian news agencies and the Defence Ministry, the aircraft went down during a scheduled flight. Search and rescue teams later located the wreckage, confirming there were no survivors.
The incident highlights the ongoing risks associated with operating aging military aircraft in high-tension regions. While the Crimean Peninsula remains a heavily militarized zone amid the ongoing conflict, preliminary official statements from Russian authorities indicate that the crash was likely the result of a technical malfunction rather than hostile action.
We at AirPro News are closely monitoring the situation as specialized investigative committees examine the crash site. The loss of the aircraft and its personnel underscores the logistical and human toll of sustained military operations relying on legacy aviation assets.
The An-26 lost contact at approximately 18:00 Moscow time on March 31, 2026, according to comprehensive research reports detailing the event. The aircraft reportedly collided with a cliff in Crimea. The 29 fatalities consisted of six crew members and 23 passengers.
“A Russian An-26 military transport plane crashed in Crimea, killing 29 people aboard,” Reuters reported.
Russian state news agencies, including TASS and RIA Novosti, relayed statements from the Russian Defense Ministry confirming the loss. Officials explicitly ruled out external factors, stating there was no damaging impact on the aircraft from missiles or drones. A specialized committee affiliated with the Defense Ministry has been dispatched to determine the exact sequence of events that led to the technical failure.
The Antonov An-26, designated by NATO as “Curl,” is a twin-engine turboprop tactical military transport aircraft. Designed by the Soviet-era Antonov Design Bureau, the aircraft was manufactured between 1969 and 1986. Industry data indicates that the airframes currently in service are several decades old. The An-26 is designed for short- to medium-haul transport, featuring a rear loading ramp. It is capable of carrying up to 40 passengers, paratroopers, or approximately 5.5 tons of cargo.
Because of its ability to operate from short and unpaved runways, the An-26 has been a mainstay for frontline logistics and medical evacuations. However, its advanced age and widespread use in challenging, austere environments have contributed to a mixed safety record, with the aircraft being involved in numerous aviation accidents over the decades. Since its annexation by Russia in 2014, the Crimean Peninsula has served as a critical logistical, naval, and military hub. It is heavily utilized by Moscow for supplying troops and launching strikes during the ongoing invasion of Ukraine. The airspace over Crimea is highly contested and heavily monitored.
The crash occurred against a backdrop of intensified military activity in the region. According to regional research reports, Ukrainian forces have increasingly targeted Russian military assets in Crimea. In September 2025, Ukraine’s military intelligence reportedly destroyed two Russian An-26 transport aircraft in a drone attack. More recently, on March 24, 2026, Ukrainian forces reportedly destroyed a Zircon hypersonic missile launcher in the area. Furthermore, on the same day as the An-26 crash, unverified reports from Ukrainian media and Russian aviation bloggers suggested the loss of a Russian Su-34 fighter-bomber.
While Russian officials have attributed the March 31 crash to a technical malfunction, we note that the heavy reliance on Soviet-era airframes like the An-26 in a high-tempo combat environment significantly increases the probability of mechanical failures. The aircraft involved was at least 40 years old, as production ceased in 1986. Sustained operational stress, combined with potential supply chain issues for legacy aircraft parts, creates a precarious situation for military logistics. Even without direct hostile action, the attrition of these transport assets represents a notable degradation of tactical airlift capabilities in a critical theater of operations.
Preliminary statements from the Russian Defense Ministry indicate the crash was caused by a technical malfunction. Officials have stated there is no evidence of external hostile impact, though investigations are ongoing.
According to Reuters and Russian official statements, all 29 people on board the aircraft were killed. This included six crew members and 23 passengers.
The An-26 is a Soviet-era, twin-engine turboprop military transport aircraft manufactured between 1969 and 1986. It is primarily used for short- to medium-haul logistics, troop transport, and medical evacuations.
