India has ordered thirty American 30 SeaGuardian UAVs, ten each for the army, navy and air force. SeaGuardian is the latest version of the American MQ-9B Reaper SkyGuardian UAV and was modified to handle maritime surveillance. This process was completed and certified in late 2020. India will pay about $3 billion for the 30 Seaguardians and that includes sensors, training and tech support.
This is something new for the United States and India because since the 1990s India has obtained nearly a hundred similar large UAVs from Israel. There were two reasons for this. Israel pioneered the development and use of these larger UAVs carrying vidcams and radar for surveillance.
The Americans developed their very successful Predator based on the Israeli originals. One difference between the Israeli and American UAVs was that early on the Americans armed their UAVs with Hellfire laser guided weapons, and equipped all these large UAVs with satellite communications. There were practical reasons for this as Predator was used overseas, usually to search for Islamic terrorists and, with the addition of Hellfire missiles, kill them. A decade later Predator was joined by the larger Reaper, which has now replaced the Predator.
The Americans also pioneered the development of laser guided bombs and missiles, putting the first of these into service during the 1970s.
