Greece and Israel To Collaborate In Producing Advanced Submarine Drone

Greece and Israel have entered into a significant defense collaboration centered around the BlueWhale, an advanced unmanned submarine system developed by Israel Aerospace Industries (IAI). On May 7, 2025, IAI announced an agreement to supply the BlueWhale autonomous submarine system to the Greek Navy. As part of this partnership, the Hellenic Aerospace Industry (HAI) will participate in the production and technological development of the BlueWhale, gaining access to IAI’s technology and contributing to projects of substantial operational significance .Defense News+10The Times of Israel+10Naval Technology+10Reuters

The BlueWhale is a 5.5-ton unmanned underwater vehicle (UUV) designed for a variety of covert maritime operations. It is capable of intelligence gathering above the sea surface, detecting submarines and underwater targets, collecting acoustic intelligence, and identifying naval mines on the seabed. Equipped with a telescopic mast housing radar and electro-optical systems, as well as advanced sonar technologies, the BlueWhale can operate autonomously for several weeks, performing many functions traditionally handled by crewed submarines .Reuters+1en.wikipedia.org+1en.wikipedia.org+12EURASIAN TIMES+12Israel Defense+12

This collaboration not only enhances the operational capabilities of the Greek Navy but also signifies a strategic partnership between Greece and Israel in the field of advanced maritime defense technologies.
