One reason that such a drone boat was created is in a suicide bombing attack on a destroyer call that occurred on October 12, 2000. Call was receiving regular refueling in the Gulf of Aden, 17 passengers were killed and 39 were injured as a result of a suicide bomb attack by a small boat approaching.
Call was equipped with Aegis system and a ship-to-air missile and it was a battle ship with excellent air defense capability and attack capability, but it was found that it can be hit hard by attack by a boat not equipped with expensive equipment , The US Navy devised a drone boat unit as a cheap and compatible measure.

For the boat autonomous operation, the technology called CARACaS was used, and in 2014 a test called "Protect manned vessels with five drone boats" was done at the James River in Virginia province.
In the demonstration experiment of 2016, the performance of the autonomous part was further enhanced, and the drone boat troops can overwhelm the enemy with this, the spokesperson said.
