Another nation acquiring land based Unmanned Air Systems for Maritime patrol. This time it is Thailand. The system chosen, the Hermes 900, may look a lot like the MQ-9B. that I think is currently the most logical choice for the USCG, but it is much smaller, more like the MQ-1 Predator. The Wikipedia entry for the Hermes 900 appears to indicate the UAS does not yet have a “sense and avoid” system (see the entry for Switzerland).
