Undersea Weapons Program

The Office of Naval Research (ONR) Undersea Weapons Program, which is managed within ONR’s Weapons and Payloads Division (Code 333), seeks to develop technologies for current and next-generation, offensive and defensive weapons capable of engaging submarines, surface ships and threat torpedoes. Science and technology efforts focus on increasing probability of kill and probability of counter-kill by improving sensor performance, engagement tactics, vehicle propulsion and warhead lethality. ONR is developing additional technologies to enable reduction of total ownership cost and increase weapon load-out. ONR is also assessing new weapon and delivery concepts.

The Undersea Weapons Fundamental Research Portfolio supports basic research (6.1) and applied research (6.2) in the following technical areas:

  • Air-independent energy and propulsion
  • Cooperative autonomous swarm technology
  • Countermeasures and counter-weapons
  • Guidance and control
  • Naval Undersea Research Program (NURP)
  • Undersea energetics
  • Undersea vehicle and weapon hydrodynamics

Research Challenges and Opportunities

Further develop promising weapon technologies and concepts through advanced technology development (6.3) and prototyping (6.4) programs support technology transition for torpedo upgrades, reduced-size torpedoes, and counter-weapons, including new weapon concepts and delivery methods. See guidance for submitting proposals and white papers for funding under this program.
