"The agreement is that, if the acquisition takes place, it will be done by the government from the government," the minister told Brussels journalists.
Lithuania's Defence Ministry decided to open talks with the Norwegian enterprise in late May.
Norway's Defence Minister Ine Eriksen Soereide told BNS she was willing "to facilitate the talks between Lithuania and Kongsberg on the matter". She did not specify that Norway would sell the missile defence systems under an intergovernmental deal.
The Lithuanian Armed Forces currently only has short-range aircraft defence systems. Medium-range systems would enable troops to reach enemy aircrafts that are located further.
