The MQ-8C Fire Scout is a Bell 407 helicopter modified with autonomous controls from the MQ-8B drone copter.
It weighs 2.7 tons, has a 1,000 lb payload, can fly for 24 hours and can carry AGM-176 Griffin missiles, APKWS II guided 70 mm rockets, and AGM-114 Hellfire missiles.
It first flew in October 2013 and the first two unmanned choppers currently involved in flight testing have already surpassed 100 flight hours.
The Navy plans to operate 28 MQ-8Cs for naval special operations forces. One of those (188688) was seen on a trailer moving northbound on Interstate 405 near Newport Beach, California.
