31. MQ-8C Fire Scout
In 2012, Northrop Grumman began developing an unmanned helicopter for the US Navy that could be deployed in the field. After just one year of research and development, the MQ-8C Fire Scout completed its first flight in 2013, and it has been deemed operational since 2019 as an autonomous helicopter.
Originally designed as a reconnaissance helicopter, the Fire Scout has also proven to be capable of providing aerial support to ground troops, staying in the air twice as long and carrying three times the weight of its predecessor, the MQ-8B.
