Less than 50% of the F-16 fighter jets delivered to Ukraine may be operational, Defense Express reports, citing a Wall Street Journal (WSJ) editorial published on 29 September. On the same day, Ukrainian President Volodymyr Zelenskyy said that Belgium would deliver three F-16 fighter jets this year.

F-16s are used extensively to intercept Russian cruise missiles and drones. As the number of Russian attacks has increased, these aircraft have become particularly important for Ukraine. However, the jets Ukraine receives are old, and keeping them flying takes regular maintenance, extra work, and hard-to-find parts.

Routine inspections are taking as long as 40 weeks in Belgium, retired US Navy Rear Admiral Mark Montgomery told the WSJ.

The maintenance process for these aircraft for Ukraine is lengthy

A likely reason for the problem is the lengthy maintenance process handled by Belgian company Sabena Aerospace Engineering, according to the WSJ, whose questions the company declined to answer. This process, according to Defense Express's estimates, takes 6–20 times longer than maintenance in the United States, which usually takes between 2 and 6 weeks. Ukraine uses the services of the Belgian company, meaning its F-16s are not being serviced quickly enough.

Delivering three additional fighter jets will not significantly help the Ukrainian military until the issue with aircraft maintenance times is resolved, Defense Express notes. The lengthy turnaround may be caused by a large maintenance backlog at the company, limited capacity, or logistical constraints, and older jets may need extra work and scarcer parts.

The delivery is part of an earlier commitment. Belgium plans to provide seven fighter jets this year: three for operational use and four for spare parts, Belgian Defense Minister Theo Francken said in June.

"I'll propose to the government to send all our F-16s to Ukraine in the coming years. It depends on having the F-35s in place because, of course, we have DCA [dual-capable aircraft] capacity. We have our role in the nuclear doctrine of NATO," Francken said.

Belgium has pledged its entire F-16 fleet of 53 aircraft as F-35s replace them, according to Defense Express.

F-16s in Ukraine have already shot down several thousand Russian aerial targets

F-16s operated by Ukrainian pilots have shot down more than 3,150 aerial targets. These include 666 cruise missiles and around 2,500 drones of various types. The aircraft have also carried out more than 650 strikes against Russian ground targets, Lieutenant General Anatolii Kryvonozhko, Commander of the Ukrainian Air Force, said during a meeting between a Ukrainian Air Force delegation and representatives of Lockheed Martin on 29 September.

At the meeting, Conor McGuire, Lockheed Martin's head of F-16 capability development, highly praised the combat use and operation of F-16s by Ukrainian pilots and the entire ground aviation personnel. He also expressed his intention to help Ukrainians enhance the capabilities of the existing platform, the statement said.

Russia's former Transport Minister Roman Starovoit shot himself dead in Odintsovo following his dismissal by President Vladimir Putin on July 7, the pro-government newspaper Izvestia reported, citing unnamed sources.

Starovoit's ouster came after nearly 500 flights were grounded at major Russian airports on July 5–6 due to security threats from Ukrainian drone attacks.

The following day, an explosion aboard the Eco Wizard tanker at the Ust-Luga port in Leningrad Oblast triggered an ammonia leak, adding to the crisis engulfing Russia's transportation sector.

Starovoit, sanctioned by Ukraine and Western countries for his role in the war against Ukraine, had served as governor of Russia's Kursk Oblast before being appointed transport minister in May 2024.

According to Russian media, Starovoit's body was found near Moscow. Preliminary findings suggest that the suicide may be linked to a possible criminal case.

Media outlets report that the former minister shot himself using an honorary firearm he had received from the Interior Ministry in 2023.

According to media reports, former Kursk Oblast official Aleksei Smirnov, who had previously served as Starovoit's deputy, had provided testimony implicating Starovoit. Smirnov himself was arrested earlier on suspicion of embezzling 1 billion rubles (over $12 million) during the construction of defensive structures in the border region.

An investigation into the large-scale theft of state funds in Kursk Oblast is currently underway, with several of Starovoit's former deputies remaining under suspicion, including Smirnov, who briefly served as acting governor.

State-controlled RIA Novosti, citing Russia's Investigative Committee, reported that Starovoit's body was discovered inside his private vehicle with a gunshot wound. Investigative teams from Russia's Main Investigative Directorate are reportedly working at the scene to determine the exact circumstances. The primary theory under consideration is suicide.

The timing of the death remains unclear. Andrei Kartapolov, head of the State Duma Defense Committee, confirmed the death to RTVI, stating only that it occurred "quite some time ago," without elaborating further.

Death of top Russian oil executive fuels fresh scrutiny of elite’s ‘window falls’

The unexplained death of a top Russian oil executive on July 4 is fueling renewed scrutiny over the rising number of high-profile Russian officials and businessmen who have died under mysterious circumstances, specifically, have fallen out of windows.

Russian President Vladimir Putin dismissed Transport Minister Roman Starovoit on July 7, following a series of high-profile disruptions to Russia's aviation and shipping sectors.

The official decree was published on Russia's legal information portal. No reason was given, but Starovoit's departure comes after nearly 300 flights were grounded at major Russian airports on July 5–6 due to security threats from Ukrainian drone attacks.

Adding to the turmoil, an explosion aboard the Eco Wizard tanker at the Ust-Luga port in Leningrad Oblast caused an ammonia leak on July 6, prompting an emergency response.

Starovoit, sanctioned by Ukraine and Western countries for his role in the war against Ukraine, had served as governor of Russia's Kursk Oblast before being appointed transport minister in May 2024.

According to the Russian state-controlled newspaper Vedomosti, Deputy Transport Minister Andrei Nikitin, a former Novgorod Oblast governor, is a leading candidate to replace Starovoit.

On July 6, the Russian Federal Aviation Agency confirmed that 287 flights were delayed or canceled at Moscow's Sheremetyevo Airport, St. Petersburg's Pulkovo Airport, and Nizhny Novgorod's Strigino Airport due to safety concerns from drone activity.

Kyiv's drone campaign, which has increasingly disrupted civilian air travel in Russia, is part of Ukraine's broader strategy to undermine Russia's logistics far beyond the front line.

Russian authorities said the ammonia leak at Ust-Luga was "minor," but the pro-Kremlin Telegram channel, Baza, reported that an unexplained explosion preceded the incident.

The Eco Wizard tanker is believed to be part of Russia's "shadow fleet" — a network of vessels used to bypass international sanctions on Russian oil and chemical exports. Five tankers have been damaged by explosions at Russian ports since the start of 2025.

The Kremlin has not made a formal statement on the minister's dismissal.

Russia has redeployed dozens of long-range bombers to more remote bases within the country, Russian independent media outlet Agentstvo reported on June 11, citing OSINT analyst AviVector.

The relocation comes in the wake of Ukraine's Operation Spiderweb, the unprecedented mass drone strike on June 1 that targeted four Russian air bases deep inside the country.  

The Security Service of Ukraine (SBU) said 117 drones were launched from hidden positions across Russia, damaging 41 aircraft, including Tu-95, Tu-22M3, and Tu-160 bombers.

According to Agentstvo, all Tu-160 bombers have been evacuated from Belaya airfield in Irkutsk Oblast and Olenya airfield in Murmansk Oblast. Some were relocated to Anadyr in Chukotka, Yelizovo in Kamchatka, and Borisoglebskoye in Tatarstan.

Tu-22M3 and Tu-95MS bombers were also redeployed. Eleven Tu-22M3s and all Tu-95MS aircraft near Murmansk reportedly relocated to the Ukrainka airfield in Amur Oblast, Engels-2 in Saratov Oblast, Borisoglebskoye in Tatarstan, and Mozdok in North Ossetia.

The reported relocation of bombers is the latest sign that Ukraine's drone warfare is forcing the Kremlin to rethink its strategic posture, even far from the front lines.

Western analysts and military officials praised Ukraine's ingenuity in the Spiderweb operation. NATO Admiral Pierre Vandier called the mission a modern reinvention of the "Trojan Horse," demonstrating Ukraine's growing technical sophistication and deep-strike capability.

President Volodymyr Zelensky claimed that roughly half of the targeted aircraft are damaged beyond repair. Russia has acknowledged losses but insisted all damaged aircraft will be restored.
