Ultra Electronics Sonobuoys fit for unmanned ASW capability

RQ-4 Global HawkUK defence electronics firm Ultra Electronics is developing a new family of miniature passive sonobuoys that could be eventually deployed from unmanned aerial systems, according to this report.

The new, 12 inch-long “F” sized sonobuoys use the company’s new multi-static technology, which assesses data from other sonobuoys and other energy in the water to provide an increased probability of detection.

The “F” size sonobouys retain the same standard sonobuoy diameter of 4.875 inches, but are two-thirds shorter than the 36 inch-long “A” active sonobuoys used by the US Navy on its P-8 Poseidon and P-3 Orion maritime patrol aircraft, and around one-quarter shorter than the standard passive “G” class sonobuoys, which measure 16.5 inches.
