The government in Warsaw has not provided details of this assistance or its value, it said.
Poland is also sending humanitarian aid to its eastern neighbour as Ukraine fights for its independence, the PAP news agency reported.
NATO leaders including US President Joe Biden are scheduled to meet for an "extraordinary" summit in Brussels on Thursday to discuss Russia's invasion of Ukraine.
NATO Secretary-General Jens Stoltenberg has said the summit will "address Russia’s invasion of Ukraine, our strong support for Ukraine, and further strengthening NATO’s deterrence and defence."
Tuesday is day 27 of the Russian invasion of Ukraine.
Poland on Tuesday reported it had taken in more than 2.14 million refugees fleeing Russia's attack on Ukraine.
