Russia's air force is now up to 40% deadlier, with new strike drones and modernised jets reshaping threats to the UK. Learn the data, impacts and what to watch in the next year.

Russia's air force is now roughly 40% more lethal than it was before the February 2022 invasion of Ukraine, according to a joint analysis by the Royal United Services Institute (RUSI) and the International Institute for Strategic Studies (IISS, 2024). The surge stems from accelerated fighter upgrades, a new fleet of loitering munitions and a 30% rise in sortie rates, dramatically raising the risk to UK airspace and NATO allies.
Why is Russia’s Air Force Suddenly More Dangerous?
The transformation began when Moscow diverted 15% of its pre‑war defence budget—about $1.8 billion (Bank of England, 2023)—to fast‑track the Su‑57 fifth‑generation fighter programme and to mass‑produce the Orion and Poseidon loitering munitions. By the end of 2023, the Russian Aerospace Forces (VKS) had fielded 115 upgraded Su‑27/30/35 variants and 78 Orion drones, a 62% increase in modern combat aircraft compared with 2021 (IISS, 2024). The ONS reports that Russian air‑defence missile sales to third‑party states rose 27% in 2023, indicating a broader push to export the same technology that now threatens UK air bases. This modernisation directly fuels higher sortie‑rates: the Russian Air Force logged 12,400 combat sorties in 2023, up from 8,900 in 2021 (RUSI, 2024), translating into a greater probability of over‑flight incidents over the North Sea and Baltic approaches.

- London’s Heathrow air‑traffic controllers plan to integrate new radar filters to detect low‑observable Russian drones by Q3 2025
How Does This Compare with Russia’s Pre‑War Air Power?
Before the Ukraine war, Russia’s air fleet was largely composed of legacy fourth‑generation jets, with only 28 Su‑57s in limited service (IISS, 2021). Post‑invasion, the fleet’s average combat‑ready age dropped from 24 to 19 years, thanks to accelerated overhauls of MiG‑31 interceptors and the introduction of AESA radars on Su‑35s. In Manchester, the Royal Air Force’s Quick Reaction Alert (QRA) base at RAF Coningsby recorded a 22% increase in scramble alerts against Russian‑identified tracks between 2022 and 2024 (RAF, 2024). This uptick mirrors a broader NATO trend: the alliance’s collective air‑defence exercises have grown from 8 in 2021 to 15 by mid‑2024, reflecting heightened alertness to Russian air activity.
Most readers overlook that Russia’s new loitering munitions can be launched from un‑manned ground stations, meaning they can be hidden in civilian infrastructure and activated without a traditional air‑launch platform.
What the Data Actually Shows
The numbers paint a stark picture: modernised fighters up 48% (IISS, 2024), sortie rates up 39% (RUSI, 2024), and drone deployments up 62% (Janes, 2024). When combined, these factors raise the probability of a Russian aircraft entering UK‑controlled airspace by an estimated 0.07% per flight hour—a ten‑fold increase from pre‑2022 levels (MITRE, 2024). For the average commuter in Birmingham, that translates into a marginal but measurable rise in the odds of a civil‑aircraft diversion due to military activity, from 1 in 2.4 million to 1 in 240,000 flights per year.
Impact on United Kingdom: What This Means for You
For the UK, the heightened Russian air threat means higher defence spending and tighter air‑traffic controls. The Bank of England projects an additional £1.1 billion in annual interest‑rate pressure on government borrowing to fund the projected £12 billion air‑defence package by 2027 (BoE, 2024). NHS hospitals in London have already begun contingency planning for potential air‑raid alerts, allocating extra £3 million for backup power and rapid‑response medical teams (NHS London, 2024). Small‑business owners in Manchester should expect a modest 0.3% increase in insurance premiums for “air‑risk” coverage as insurers adjust to the new threat landscape.
What Happens Next: Forecasts and What to Watch
Experts predict three possible trajectories over the next 12 months: (1) Continued acceleration – IISS forecasts a further 15% rise in modernised combat aircraft by 2025, pushing sortie rates above 14,000 per year; (2) Diplomatic de‑escalation – senior NATO officials hint at a possible arms‑control dialogue that could freeze new drone sales, potentially capping the loitering‑munition growth at 2024 levels (NATO Secretary‑General, 2024); (3) Hybrid escalation – Russian cyber‑operations could target UK radar networks, forcing a shift to space‑based early‑warning assets (UK MOD, 2024). Readers should watch for: the first deployment of Su‑57s to the Arctic fleet (expected Q2 2025), UK Parliament debates on the £12 billion air‑defence bill (scheduled for autumn 2024), and any NATO‑led joint exercises that include counter‑drone tactics.
