Abstract: We envision the Mid-Frequency Active Sonobuoy (MFAS) design being an A-size sonobuoy that functions as an off-board mono-static, bi-static and multi-static sensor across multiple ASW platforms. Our design for MFAS will be based on design trades iterated across mission, CONOPS, and the SWAP-C (Size, Weight, Power and Cost) considerations that drive A-size packaging constraints and recurring costs (production and mission). The MFAS design will be based on SWAP-C enabling technologies for receive arrays, projector arrays, power amps and batteries. The MFAS will be designed to meet performance requirements derived from supporting mission analysis and CONOPS studies. The ultimate purpose is to maintain a high Pd and wide area coverage while maximizing platform interoperability and being cost effective for the MFAS and the total mission. This MFAS functions as an off-board, mono-static, bi-static or multi-static buoy and is used to extend platform ASW capabilities in both search and localization scenarios.
Benefits: The benefits an MFAS brings to the US Navy is a significant improvement in our ASW effectiveness by bringing multi-static capability and interoperability across key ASW platforms. The MFAS will also benefit some ASW platforms such as the MH-60R and the unmanned MQ-8C (Firescout) by having two buoy functions (a receive array and a projector array) combined into one buoy instead of the traditional two buoys. This will reduce payload volume and weight, which is critical to all ASW platforms. In addition, it is anticipated that the technology improvements/evolutions required to realize an A-size packaged MFAS bring opportunities for technology transition to improve other sonobuoy designs and ASW programs. On a pure non-DOD side, we envision that MFAS or an MFAS variant could be used in support of ocean oil and gas exploration and asset protection as well as for academic research.
