Two main interceptors are at the center of the response to Russia's jet-powered Shaheds

1. SkyFall P1-SUN JetKiller (Ukrainian)

What it is: An upgraded, faster variant of SkyFall's existing P1-SUN interceptor, explicitly designed to chase down Russia's new jet-powered Shahed drones. It was unveiled at the Farnborough Airshow on July 21, 2026 .

Speed: Up to 370 km/h (~230 mph), a significant increase from the original model's 310 km/h .

Key capabilities: Operates at altitudes up to 9,000 meters, uses AI to autonomously detect and lock onto aerial targets, and has a range of up to 120 km (75 miles) .

Development timeline: SkyFall says they started work on this faster version only about three months ago (around April 2026) .

Battlefield results: The company claims the JetKiller has already been tested in combat and has downed more than a dozen jet-powered Shaheds .

Production timeline: SkyFall plans to begin mass production in August 2026 .

2. Firebolt Engineering Griffen (British-Ukrainian joint venture)

What it is: A jet-powered fixed-wing interceptor developed by British-Ukrainian company Firebolt Engineering. It is the first interceptor drone verified to have shot down a Russian Shahed in combat .

Speed: The company states a top speed faster than 350 km/h (~217 mph) .

Key capabilities: Fixed-wing jet-powered design, operating altitude over 7,500 meters (~24,600 feet), a range of up to 120 km (75 miles) .

Development timeline: The Griffen is the product of a joint Ukrainian-British development effort, matured over the first half of 2026 to reach operational deployment by July .

Battlefield results: On July 7, 2026, Firebolt Engineering confirmed the first verified combat interception of a Shahed-type drone (Geran-2) by the Griffen in Ukraine . This marks the first known instance of a jet-powered interceptor drone downing a Shahed in theater.

Production timeline: Firebolt Engineering's stated goal is to mass-produce the Griffen and deploy it in significant numbers to help Ukraine cover its vast frontline airspace . No specific month for mass production was provided in the available sources, but the system is already in active combat use.

Context: Why these were developed

Russia has been deploying growing numbers of jet-powered Shahed variants that can reach speeds of up to 500 km/h (~310 mph), significantly outpacing earlier propeller-driven Shahed models and making them much harder for conventional low-speed interceptors to catch . Both the P1-SUN JetKiller and the Griffen were direct responses to this new speed gap.
