A group or swarm of vehicles may be configured to move together in a predetermined formation. Each vehicle may include a navigation and communication system configured to provide communication and to determine accurate relative position, navigation, and time information for each vehicle in the group. Each vehicle may include a second radio frequency transceiver configured to receive and transmit in the high frequency (HF) or lower radio frequency band, and to measure and control the timing of the reception and transmission of the HF signals in relation to the timing of the reception and transmission of the HF signals with the other vehicles in the group to form an antenna propagation pattern to communicate over beyond line-of-sight distances.
