The United States and Ukraine are working together to put fresh missiles into Ukraine's aging Soviet-era S-300 air defenses, retired US Army colonel Robert Hamilton told PBS NewsHour. These long-range systems shoot down aircraft, but the missiles that feed them have been depleted. The effort—retrofitting old rounds or building a newer variant—would revive launchers Ukraine already owns.

Ukraine's air defense runs on a shrinking supply of interceptors, with Russian ballistic and drone strikes outpacing what allies can ship. The chokepoint is production capacity, not willingness—and Hamilton frames the S-300 rebuild as one of the slower-burn fixes that ease the strain on scarce Western systems rather than replace them.

A working system near the end of 2026

Hamilton, who heads the Delphi Global Research Center, said the joint effort should come online near the end of 2026 and could turn out "100 or a couple of hundred" anti-aircraft missiles a year. He described the work as an effort to "essentially retrofit or upgrade the old S-300 missiles or a newer variant of the S-300" and give the system better capabilities.

Ukraine drones hit Crimea’s S-300/S-400 near Kerch—and knocked out power across four occupied territories overnight

In September 2024, then-US Defense Secretary Lloyd Austin announced at the Ramstein contact group that Washington, in partnership with several European companies, was working with Ukraine to "design and build a substitute" for the Soviet S-300 and the R-27 air-to-air missile used by fighter jets. He never spelled out what that substitute would be.

Why Ukraine's S-300s ran law

When Russia launched its full-scale invasion in 2022, Ukraine held roughly 25-30 S-300PT/PS battalions in varying states of readiness. As the missiles ran out, Kyiv came to lean on Western air defense systems and interceptors while Russia keeps launching mass strikes.

“Very good results” – Wave of Ukrainian strikes across Russia and Caspian Sea overnight target warships, air defenses, logistics

Anything Ukraine can build or rebuild on its own soil is a supply that no foreign stockpile or political fight can cut off.

That same logic is pushing Kyiv toward co-producing Patriots with US firms and fielding its own ballistic interceptor—a race to turn air defense into a domestic industry before the next winter of strikes.

Ukraine's Main Directorate of Intelligence (HUR) destroyed a Pantsir-S1 air defense system worth an estimated $15 million and a military crane in occupied Crimea, HUR reported. The agency's Group 13 used maritime drones as drone carriers to deliver the strikes on ground targets. Separately, monitoring channels reported explosions across the peninsula from Kerch to Sevastopol overnight on 7 August, hitting the airfield Russia uses to launch Shaheds at Ukrainian cities.

FPV drones launched from Magura platforms destroy air defense

HUR's Group 13 used Magura naval platforms as floating carriers for FPV drones. The drones flew from the platforms to strike a camouflaged Pantsir-S1 and a military crane on land, the agency's video shows. HUR estimated the destroyed air defense system at $15 million.

HUR did not specify the exact location but said the operation took place in early August 2026. The Pantsir-S1 is a short-range gun-and-missile system Russia deploys to protect higher-value assets such as S-400 batteries and command posts. Each one destroyed leaves a gap in the layered coverage Russia relies on over the peninsula.

The agency noted that Group 13 operators recently struck a Podlyot radar control vehicle and a Parol-4 radar interrogator in Crimea as well.

The Pantsir kill adds to a months-long campaign that has destroyed nearly 200 Russian air defense assets in the first half of 2026 alone by the Unmanned Systems Forces.

Overnight strikes sweep peninsula from Kerch to Sevastopol

Separately, overnight on 7 August, Ukraine struck at least six locations across occupied Crimea.

Monitoring Telegram channel Krymsky Veter reported explosions and gunfire in Kerch at 02:38. Near Alushta, four strong explosions were heard in the village of Malorichenske close to a large power substation. In Sevastopol, mobile fire groups engaged targets without an air-raid alert, and residents reported a powerful explosion near Cape Fiolent.

Ukraine’s sea drone that never touched the shore struck two Russian radars in occupied Crimea

The heaviest strikes hit the Hvardiiske military airfield, which Russia uses to launch Shahed attack drones against Ukrainian cities. Hits landed in two waves, from 03:30 to 03:39 and from 04:34 to 04:47. A fuel and lubricants depot caught fire, and small-arms ammunition began detonating, Krymsky Veter reported. Residents described two fire sites visible for kilometers. The Crimean Bridge was temporarily closed during the strikes.

In Feodosia, initial reports of a strike on the oil depot were corrected: the hit likely landed on a concentration of Russian military equipment at the former 13th military compound on the Kerch Highway. Krymsky Veter noted the same compound was struck on 22 June. A vessel also burned at sea off Gelendzhik overnight.

No official confirmation of the strikes' results has been issued. 

Latvia will open military mobilization centers in four cities and build anti-tank barriers in its capital this week as the Baltic NATO member rehearses wartime call-up procedures, Latvian Public Media (LSM) reported. The drills come as multiple Western intelligence agencies have warned that Russia may test NATO's eastern flank with a limited military provocation within years.

Latvia rehearses crisis conscription

On 8 August, Latvia's National Armed Forces (NBS) will deploy mobilization centers in Rīga, Kuldīga, Valmiera, and Alūksne. The purpose is to train and improve procedures for calling up and conscripting Latvian citizens in a crisis. Citizens who applied for voluntary reserve training will report to the centers and travel to the Infantry School in Alūksne for a three-week military course.

The course, running from 8 to 29 August, will train 114 reservists in weapons handling, combat shooting, communications, topography, terrain orientation, field combat, and advanced first aid. After completing the program, reservists will take the soldier's oath, receive a reserve soldier's certificate and a mobilization order. Reserve soldiers must refresh their skills every four years.

Both women and men — Latvian citizens aged 18 to 60 with at least primary education, intermediate Latvian, no criminal record, and good health — can apply.

Today, on 7 August, a separate exercise in the capital will test Riga's ability to erect anti-mobility engineering structures — physical obstacles designed to slow enemy forces in urban environments.

What Moscow does to foreign embassies, Latvia will now do to Russia’s

Defense preparations accelerate amid Russian threats

The drills are the latest in a series of concrete defense steps Latvia has taken as the threat from Russia grows. 

Latvia's military chief warned in June that Russia could exploit its drone advantage to attack the Baltics by the end of 2028. In July, Latvia hardened security at its hydroelectric dam and gas storage facility after intelligence flagged specific Russian threats, and its prime minister asked NATO for more troops and air defense. 

Latvia completed a 280-km border fence in late 2025.
