| The next step was to put the buoy into a standard sonobuoy launch package. |
| In 1965, work had started on sonobuoy systems using ESS to be integrated with the Berkut radar. |
| Another invention was the American 3-cm radar and sonobuoy. |
| The full ASW fit would include a MAD boom, rotary sonobuoy dispenser under the rear fuselage, torpedo bays in enlarged sponsons, and four anti-ship missiles under the wings. |
| The Vertical Line Array sonobuoy, pioneered by NRE in the 1960s and developed by industry in the 1970s, has been in service with the Canadian Forces for many years. |
| Minutes after the sonobuoy was in the water, the faint sound of a submarine screw entered the headphones of a young petty officer aboard the helicopter. |
