Tusk said the government would work to expand Poland's air defence capabilities wherever possible, with particular attention to the country's eastern regions under the government's East Shield defence programme.
"We are safer on the eastern border today than ever before," Tusk said at a news briefing in the southern city of Kraków.
He said Poland was spending more on military procurement and air defence than any other country, drawing on both government funds and European Union financing, including the bloc's SAFE defence financing programme.
Tusk also cited tighter security along Poland's border with Belarus as evidence of improved security. He said the number of people crossing illegally had fallen from a peak of several thousand a month to "zero, two or three" crossings a month.
Tusk said the East Shield programme would never be fully completed because a key part of it involved continually modernising Poland's air defences.
"We are at the beginning of this road," he said.
The programme, announced by Poland's defence ministry and military in 2024, is designed to strengthen the country's borders with Russia and Belarus. It includes fortifications, equipment storage facilities, reconnaissance systems and anti-drone installations.
Tusk was also asked about recent comments by Brig. Gen. Michał Marciniak, deputy head of the Armament Agency and the man in charge of the Polish military's Integrated Air and Missile Defence Programme, who said that large Polish cities were not protected by missile defence systems because such systems had not been deployed around them.
