Ukraine Defense Intelligence (DIU) said that a special forces unit had "successfully detected and destroyed" a Russian Buk-M3 surface-to-air missile system on Sunday.
The DIU said that the important Russian defensive asset, valued between $40 to $50 million (€34 to €42 million), was struck in the occupied Zaporizhzhia region in southeastern Ukraine.
Ukraine's military said the missile system — which can engage airborne targets and both sea and land-based targets — was located near Oleksandrivka in the Melitopol district.
The claim cannot be independently verified.
The reports come as Ukraine has increased attacks on Russian infrastructure, with recent claims of attacks on oil refineries and railway lines in a bid to disrupt Russian military fuel supplies and cut off a critical source of Moscow's funding for its ongoing invasion.
On Sunday, Ukraine said it had struck the Kirishi oil refinery, one of Russia's largest.
The refinery in Kirishi is located 110 kilometers (68 miles) southeast of St. Petersburg and 800 kilometers north of Ukraine.
