How far can the FP-1 drone fly?

What is the difference between FP-1 and FP-5 Flamingo?

The FP-1 is a one-way attack drone typically used against area targets. The FP-5 Flamingo is a cruise missile with a longer range (3,000 km), larger warhead (1,150 kg), and precision strike capability.

Background

The FP-1 is a Ukrainian-developed long-range one-way attack drone used in deep-strike operations against Russian territory. On 28 March 2026, FP-1 drones struck the YANOS oil refinery in Yaroslavl, igniting fires across at least three sections and contributing to Russia's cascade refinery disruptions. The Yaroslavl strike placed the FP-1's operational reach at approximately 1,100 km from the Ukrainian front line.

The FP-1 represents the lower-cost tier of Ukraine's long-range strike arsenal, complementing the larger FP-5 Flamingo cruise missile. It is a one-way attack drone designed for area targets such as refineries and storage facilities rather than hardened point targets. Ukraine has deployed FP-1 drones in coordinated multi-axis strikes alongside FP-5 missiles, maximising the number of simultaneous targets and saturating Russian air defences.

Precise specifications remain classified, but the FP-1's demonstrated range and its role in the Yaroslavl strike confirm Ukraine has developed an operationally significant deep-strike drone capability beyond Shahed-pattern systems. The drone programme represents a shift from reactive air defence to proactive strategic depth attack.

How the World Sees Them

Russia

Moscow has reported drone attacks on Yaroslavl without specifying the weapon system; Russian air defences have struggled to intercept FP-1-class systems at scale given simultaneous multi-axis saturation.

Ukraine

The FP-1 is a cornerstone of Ukraine's strategic depth campaign; its low unit cost relative to cruise missiles allows mass employment against area targets across Russia's industrial interior.

Western analysts

The FP-1's reach to Yaroslavl at 1,100 km confirms Ukraine has independently developed a long-range drone capability that changes the strategic calculus for Russian rear-area security.
