Stand-off anti-submarine warfare engagement

Funds research into stand-off weapons and sensors that let EU navies engage submarines from beyond torpedo range.

This topic is one of eight Research Action lines opened together under the same EDF-2025-RA call, each carrying its own separate budget, and this one carries an indicative topic budget of EUR 20 million funded as actual-cost grants, so reimbursement tracks costs the consortium actually incurs rather than a fixed lump sum. It is a single-stage call: proposals go straight to a full application, with

This topic funds early-stage research into a stand-off anti-submarine warfare capability — a sensor-to-effector chain that can detect and strike submarines and large underwater drones from more than 40 nautical miles away. It wants proposals combining lightweight torpedo technology, rocket or drone-based delivery, and improved underwater sensor suites so surface warships aren't limited to aircraft-dependent engagement. The work should also explore effector components that can double up on unmanned aerial or surface vehicles for other missions.
