Since 2004 March 10, after Lithuania became a member of the North Atlantic Treaty Organization (NATO), it has been committed to improving national security and close cooperation with NATO countries. Therefore, military mobility is one of the priority areas of the state. However, it is impossible to fulfil this obligation without inadequate infrastructure. Digitization of seaports is one of the most important processes to increase operational efficiency, competitiveness, and adaptability to changing circumstances. Digitization allows you to optimize seaport operations, monitor real-time changes, and integrate your transport with other parts of the transport chain. It also ensures the safety of cargo and ship movement. The cargo and goods information system (KIPIS) operates in Lithuania’s maritime sector.

However, military cargo transportation faces various challenges, such as the constant information change and the lack of storage space for military equipment. The article aims to assess the infrastructure of the Klaipeda State Port for the host country’s support and to make suggestions for future development. To achieve the goal, an analysis of the scientific literature on seaport activity and infrastructure was carried out based on secondary data, the existing infrastructure of Klaipeda State Ports was reviewed, and based on primary data, proposals for improving the infrastructure of Klaipeda State Port will be formulated, assessing the scale of the host country. A systematic and comparative analysis of the concepts published in the scientific literature, statistical processing, in-interview, and Kendall’s methods of expert compatibility were used to achieve the purpose and tasks of the article.
