 Russian Aerospace Forces have problems because of war and sanctions. Russian Aerospace Forces aircraft are wearing out faster due to the intensive amount of sorties as part of combat operations and maintenance and repair are complicated by sanctions which threatens them with problems in the future. British Ministry of Defence Intelligence reported this. UK Defence Intelligence stated that the Russian Aerospace Forces has lost about 90 fixed wing aircraft since the start of the full-scale war. Some of the remaining military aircraft are flying far more sorties than in peacetime. All aircraft have a projected lifespan in flying hours. It is highly likely that with this extra wartime use Russia is eating into many of its airframe's lifespans far more quickly than the Russian Aerospace Forces planned for. The need for extra maintenance is complicated by a shortage of spare parts because of increasing demand and international sanctions Defence Intelligence stated. UK Intelligence noted that so far the Russian Aerospace Forces are retaining the ability to fly over the occupied territories of Ukraine. However, since the war has been going on for much longer than the Russian Ministry of Defence originally planned, the deterioration of the aircraft is likely to affect the combat capabilities of Russian aviation in the long term.
