As Russia ramps up missile and drone attacks, Ukraine is set to strengthen its air defenses with new Western support: five Patriot missile systems and 220,000 rounds for Gepard anti-aircraft guns.

Announced during the latest Ramstein-format meeting, the pledge marks a significant upgrade to Ukraine’s layered air defense network.

BBC explores how these deliveries could shift the balance—and why speed and supply will be key.

Patriots: Expanding missile shield, but time matters

The US-made Patriot system is Ukraine’s main defense against ballistic and cruise missiles. According to New York Times reports, Ukraine currently has eight Patriot batteries, though only six were operational as of May 2025. The new systems could increase that number to 13.

Each battery includes:

• Missile launchers
• Radar
• Command unit
• PAC-3 interceptors, capable of downing advanced ballistic threats

But timelines remain uncertain. Germany’s Spiegel reports the first new system may not arrive before March 2026. President Zelenskyy has said 25 Patriots are needed to secure the country—meaning even after this delivery, Ukraine remains far from that goal.

There’s also a shortage of PAC-3 missiles, raising concerns about sustaining the new systems once deployed.

Gepards reloaded: Short-range defense gets ammo

Ukraine’s Gepard anti-aircraft guns have proven essential for shooting down Shahed drones and low-flying missiles. The country operates about 100 Gepards, each armed with twin 35mm cannons and radar.

The new shipment of 220,000 rounds will allow for three full reloads across the fleet.

Ammo had become a bottleneck after Switzerland blocked re-exports, citing neutrality. Germany’s Rheinmetall stepped in, restarting production to fill the gap.

Military analysts estimate a single Shahed can often be downed with just 7–30 rounds, meaning this batch could neutralize thousands of drones—a crucial upgrade as Russia continues near-nightly drone assaults.

A layered strategy for a shifting threat

Russia’s aerial tactics are evolving. Drones now fly extremely low or at high altitudes to avoid detection, testing Ukraine’s defenses.

Kyiv is responding with a layered air defense approach:

• Patriots for long-range missiles
• Gepards for drones and close-range threats
• Mobile air defense and electronic warfare to fill the gaps

Even with 13 Patriot systems, Ukraine cannot cover its entire airspace. But together, these tools help protect cities, infrastructure, and military sites more effectively.

BBC verdict: A critical step, not a final answer

This package—five Patriots and 220,000 Gepard shells—is one of the most impactful pledges yet. But delays in delivery and limited missile stocks could slow its effect.

Ukraine has the plan. The tools are arriving. But the outcome will depend on how fast systems are delivered, how well they’re supplied—and whether support continues as the threat evolves.
