The Israel Navy is evaluating the acquisition of American Boeing P-8 Poseidon aircraft to bolster its maritime surveillance and submarine detection capabilities. Israeli Navy Commander Eyal Harel has held discussions with Boeing executives regarding the potential purchase, which is expected to be part of a ten-year strategic plan presented to the General Staff by the end of the year.

The move is intended to address shifting naval power dynamics in the Eastern Mediterranean and Red Seas. Israel aims to expand its operational reach to monitor growing submarine fleets in the region, specifically noting the presence of submarines from Turkey, Egypt, and Greece, as well as securing maritime routes in the Gulf and the Bab al-Mandab strait.
