Navy Helicopter Drone Completes First Round of TestingLiveScience.com
By Elizabeth Palermo 10 hours ago
Imagine trying to land a remote-controlled helicopter on top of a motorboat that's speeding across a lake. Now imagine that the helicopter is life size, the motorboat is a warship and the lake is the Atlantic Ocean. Navy pilots recently had to contend with just such a scenario as they tested the U.S. military's newest drone, the MQ-8C Fire Scout.
From a computer-filled control station aboard the USS Jason Dunham, the pilots successfully completed 32 takeoffs and landings with the new drone helicopter. The Navy conducted the tests, which ended yesterday (Dec. 23), to assess the drone's capabilities in different wind conditions, and to see how well it could land on a ship moving at varying speeds, according to Navy officials. In addition to landing and taking off, the Fire Scout also completed three test flights, presumably traveling out of view of the USS Dunham and then returning to the ship.
"The MQ-8C Fire Scout's flights from the USS Dunham represent a significant Navy milestone. This is the first sea-based flight of the MQ-8C, and the first time an unmanned helicopter has operated from a destroyer," Capt. Jeff Dodge, Fire Scout program manager with Naval Air Systems Command (NAVAIR), said in a statement. Destroyers are typically smaller than other ships from which drones may be flown, such as aircraft carriers.
The Fire Scout is a modified version of a Bell 407 utility helicopter, an aircraft used by governments, militaries and private organizations around the world. But the MQ-8C and its predecessor, the smaller MQ-8B, don't have pilots in their cockpits. Instead, operators fly these helicopters remotely, from control stations located aboard ships or on land.
The MQ-8B was first deployed by the U.S. Navy in 2009 and has since been used for intelligence, surveillance and reconnaissance missions. The MQ-8C is expected to serve a similar purpose. However, this newer aircraft can carry more weight than its predecessor (about 1,000 lbs., as opposed to 600 lbs.), and it can stay in the air longer than its smaller cousin — about 12 hours if it's carrying only 300 lbs. The MQ-8B can fly for only 5.5 hours at a stretch when carrying the same 300 lb. payload.
Unlike the military's other drones, which are fixed-wing aircraft, both versions of the Fire Scout can land and take off vertically, which means they don't need the giant deck of an aircraft carrier to operate. Both helicopters can operate aboard relatively small ships, like the USS Dunham.
The military also has another drone helicopter at its disposal, the K-MAX unmanned multi-mission helicopter, which was deployed in Afghanistan in 2011. The K-MAX drone is used to carry supplies to troops in remote or dangerous territories. It's also been used for "hot hookups," in which soldiers on the ground hook cargo to the helicopter as it hovers in the air.
It's not clear whether the MQ-8C was designed with these kinds of cargo pickups in mind, but the drone could be used for search and targeting missions, said Darren Dugan, a commanding officer aboard the USS Dunham.
U.S. defense contractors are also working on several other variants of pilotless helicopters, including an unmanned version of the iconic Black Hawk helicopter, which could one day be used to deliver cargo — and even troops — into battle. An unmanned medical transport helicopter is also being developed, as well as vertical takeoff and landing (VTOL) drones that combine the hovering capabilities of a helicopter with the speed of an airplane.
