Mariusz Błaszczak made the announcement at a security conference in Warsaw on Tuesday, Polish state news agency PAP reported.
Six more Patriot batteries for Poland
Błaszczak said: “We are launching phase two of the Vistula air defence programme - I have signed a Letter of Request for the purchase of six more batteries of the Patriot system.”
He told the Defence24 Day conference that the Patriot batteries included "radars, launchers and a supply of rockets." He added that Poland would also receive training and logistics support.
Phase one of Poland’s Vistula mid-range air defence programme was launched in 2018 and includes the delivery of two Patriot batteries this year.
Tuesday's announcement by Poland comes as the Russian invasion of neighbouring Ukraine enters its fourth month.
