Ukraine Confirms First Combat Use of “Sapsan” Ballistic Missile as Kyiv Expands Long-Range Strike Arsenal

Ukraine has officially begun using its indigenous “Sapsan” operational-tactical ballistic missile system in combat, President Volodymyr Zelensky has confirmed, marking a major expansion of Kyiv’s home-grown long-range strike capability. Alongside “Neptune”, “Palianytsia” and “Flamingo” cruise missiles, the new system gives Ukraine an increasingly diversified ability to hit Russian targets far beyond the front line.

Speaking in a recent Q&A, Zelensky said Ukraine is already using “Neptunes, long Neptunes, Palianytsia, Flamingo – and also Sapsan”, adding that he would not disclose quantities so as not to reveal “all the precedents and details” to Russia. He stressed that “Neptunes are really working well”, and that Russian forces often misidentify which type of weapon has struck them – something Kyiv sees as an advantage. 

Sapsan: Ukraine’s First Indigenous Tactical Ballistic Missile

The Sapsan (also known as Hrim-2 / Grom-2) is a Ukrainian operational-tactical ballistic missile system developed by the Yuzhnoye (Pivdenne) design bureau and produced by Pivdenmash. It is mounted on a wheeled transporter-erector-launcher, allowing rapid shoot-and-scoot operations similar to Russia’s Iskander-M.

Open-source assessments and Ukrainian reporting indicate the following approximate performance:

• Range:

  • Export “Hrim-2” variant: about 280–300 km, restricted to comply with the Missile Technology Control Regime.

  • Domestic “Sapsan” variant: up to 500 km, allowing deep strikes into Russian rear areas. 

• Speed:
  The missile is believed to reach over Mach 5 at peak, with some sources describing speeds in the Mach 4–5+ class, making interception significantly harder than subsonic cruise missiles. 

• Warhead:
  Sapsan carries a high-explosive warhead of roughly 400–500 kg, with several Ukrainian and analytical sources specifically citing about 480 kg – more than double the payload of a U.S. ATACMS in some configurations. 

In May–June 2025, Ukrainian and Western reports indicated that Sapsan had already conducted successful combat trials, striking Russian military targets at nearly 300 km range and moving into mass production during the summer. 

With Zelensky now confirming its operational use, Sapsan becomes a key element in Kyiv’s strategy to reduce dependence on Western-supplied ATACMS and to maintain a long-range strike option even if foreign stocks become constrained.

Neptune and “Long Neptune”: From Coastal Defense to 1,000 km Strike Weapon

Ukraine’s missile renaissance began with the R-360 “Neptune”, originally an anti-ship cruise missile developed from the Soviet Kh-35 and fielded as a coastal defense system. Early in the full-scale invasion, Neptunes gained global attention after being credited with the sinking of the Russian cruiser Moskva.

The original R-360 Neptune has been widely reported with:

• Range: about 280 km in its standard anti-ship configuration, with later land-attack adaptations reaching 300–400 km. 

• Speed: roughly 900 km/h, a typical subsonic cruise profile.

• Warhead: about 150 kg high-explosive in the baseline anti-ship version.

Since 2024–2025, however, Ukraine has showcased a dramatically upgraded “Long Neptune” variant:

• Range: up to 1,000 km, according to Ukrainian officials and multiple independent assessments, enabling strikes deep into Russia, including targets like Novorossiysk and Tuapse. 

• Speed: around 900–950 km/h, still subsonic but optimized for long-range endurance.

• Warhead: open sources indicate a heavier payload of roughly 260 kg or more compared to the original 150 kg, though precise figures remain officially undisclosed. 

By pairing Long Neptune with Sapsan, Ukraine now fields both a long-range cruise missile and a fast ballistic system, complicating Russian air and missile defense planning.

Palianytsia: The “Rocket-Drone” for 600+ km Deep Strikes

The “Palianytsia” (often transliterated Palianytsya) is described by Kyiv as a hybrid between a cruise missile and a long-range attack drone. It was first unveiled publicly in August 2024, after suspected use in strikes against Russian ammunition depots far beyond the front line.

After initial secrecy, Ukraine’s state defense conglomerate Ukroboronprom disclosed detailed specs in 2025:

• Range: up to about 650 km, with earlier estimates putting it in the 600–700 km band.

• Speed: a maximum of roughly 900 km/h, comparable to Russian Kh-101 cruise missiles. 

• Warhead / Payload: around 100 kg of payload, typically a high-explosive warhead.

Flying at low altitudes between 15 and 500 meters and guided by INS + GPS, Palianytsia is designed to slip through gaps in Russian radar coverage and attack high-value targets like ammunition depots, air bases and logistics hubs. 

For Ukraine, Palianytsia fills an important niche: cheaper and lighter than Flamingo, but fast and long-ranged enough to threaten important military infrastructure hundreds of kilometers inside Russia.

Flamingo (FP-5): A 3,000 km Heavy Cruise Missile

The most dramatic of Ukraine’s new systems is “Flamingo”, also known as FP-5, a large ground-launched cruise missile developed by Ukrainian private firm Fire Point. It was formally presented in August 2025 and has since moved into early serial production.

Key known characteristics from Ukrainian and international analyses include:

• Range: around 3,000 km, allowing strikes far into the Russian interior and potentially beyond. 

• Speed: subsonic, up to about 900–950 km/h, with reported endurance of around four hours of flight. 

• Warhead: a massive 1,000–1,150 kg high-explosive payload, placing Flamingo in the same weight class as – or heavier than – well-known systems like the U.S. Tomahawk or Russian Kh-101.

Flamingo’s ability to fly at very low altitude, sometimes below 50 meters, and to follow complex routes is intended to “outsmart” Russian air defenses and radar coverage. 

According to Zelensky and Ukrainian media, Flamingo has already been used in multiple real operations, with at least nine confirmed combat launches reported by Ukrainian sources by late 2025.

A New Phase in Ukraine’s Long-Range War with Russia

Taken together, Sapsan, Neptune / Long Neptune, Palianytsia and Flamingo represent a rapid and deliberate build-up of Ukraine’s domestic long-range strike complex since Russia’s full-scale invasion in 2022. International reporting notes that Kyiv now fields a mix of ballistic missiles, heavy and light cruise missiles, and long-range “kamikaze” drones capable of reaching hundreds to thousands of kilometers beyond the front line. 

By confirming that Sapsan has moved from testing into actual combat use, Zelensky is signaling that Ukraine’s long-promised indigenous ballistic missile is no longer just a development project but an operational tool. Its combination of:

• High speed (Mach 4–5+),

• Heavy warhead (around half a ton), and

• 500 km domestic range

gives Kyiv a way to strike hardened targets like command bunkers, airfields and logistics nodes on timelines and trajectories that differ sharply from cruise missiles.

At the same time, by refusing to reveal how many missiles have been produced or used, and by allowing Russia to misguess whether a strike was carried out by Neptune, Palianytsia, Flamingo or Sapsan, Ukrainian officials are using ambiguity as a weapon – forcing Moscow to stretch its air defenses over a growing volume of sky and a widening list of threats.
