Navy MQ-4C Triton - High Altitude Maritime Autonomous Drone -- Will Deliver Later This Year

The Navy is Preparing the MQ-4C Triton Maritime Drone for Service in the Pacific Theater; the drone is now being configured with collision avoidance technology and advanced maritime sensors enabling it to zero in on enemy ships at sea.

The Navy and Northrop Grumman are updating software and sensors on a new high-tech, autonomous maritime drone designed to identify and zero in on enemy ship targets at sea, service and industry officials said. 

The Navy's Triton autonomous drone, called the MQ-4C, is now receiving a "3.1 software" integration as part of a technical plan for the aircraft to be operational by 2018. The first Tritons are slated to deliver sometime later this year, developers said. 

"3.1 software gets you to the point where you can use the sensors in an operational environment," Tom Twomey, senior manager business development, Triton, Northrop Grumman, told Scout Warrior in an interview. 
The sensor package being designed for the aircraft includes what the Navy calls a multi-function array sensor, or MFAS.
The Triton's electronics include an electro-optical/infrared sensor, a 360-degree active electronically scanned array radar and inverse synthetic aperture radar (ISAR), among other things, Navy developers have said. The sensors create a common operational maritime picture including images, data and full-motion video. An electronic support measure is also able to detect maritime signals. 
Synthetic Aperture Radar, or SAR, sends an electromagnetic signal forward and then analyzes the return signal to paint a picture or "rendering" of the terrain below. SAR is primarily used for land missions, whereas ISAR is especially engineered to zero in on targets in a maritime environment. 
"Inverse synthetic aperture radar is a mode that allows you to stop on one particular target and get an ID on that. It gives you a picture of a ship showing the superstructure in order to see if, for example, it is a tanker or warship. It can pick steel out of the water," Twomey said.



Designed to function as a maritime version of the Air Force's Global Hawk surveillance plane, the Triton is designed for high-altitude, long-dwell ISR missions - the kind of technology suited for the geographically dispersed Pacific theater. The Air Force already has RQ-4 Global Hawks stationed at Andersen Air Force Base in Guam.
The Triton is built with a thicker, more stiffened wing compared to the Global Hawk to enable the aircraft to rapidly change altitude in adverse or icy weather conditions, he added.

The Navy also separately tested the Triton's software and sensor systems by flying them in a surrogate Gulfstream 2 airplane.

The Triton is designed to bring endurance, altitude, range and persistent stare ability over a wide, expansive area; it can stay on missions for over 24 hours at altitudes greater than 50,000 feet, Navy developers explained. 
The Triton can cover broad areas out on the ocean in a single mission. The idea is to provide ship commanders with an ability to detect and see targets, threats and items of interest in real time from great distances using the sensors, cameras and data-links of the Triton system.
 
The Triton is an autonomous air vehicle able to chart a course without needing to be remotely piloted, Twomey explained. Computer algorithms and on-board systems enable the aircraft to account for wind, temperature and altitude conditions. 
"You load in a complete mission plan, but if you need to change, there is an ability to override the autonomy. It will correct the path and tell you where you need it to go," he said. 

The Navy has also announced that next generation aircraft avoidance systems are being installed on the Triton.

Last year, Northrop Grumman received a $9.6 contract to install the Automatic Response Module of the Airborne Collision Avoidance System X into the MQ-4C Triton’s avionics system.

The company will test and support the software and ensure the proper functioning of the unmanned aircraft.

The Airborne Collision Avoidance System X charts flight patterns that permit closer navigation to other aircraft while maintaining safety protocols. According to the MIT Lincoln Laboratory, the advanced tracking algorithms employ “probabilistic models to represent various sources of uncertainty (e.g., pilot nonresponse, surveillance errors, etc.) and computer optimization to consider safety and operational objectives as defined by system experts and operational users.”

Equipped with signals intelligence, C4ISR, and maritime strike capabilities, the Triton represents the Navy’s future in unmanned aircraft technology. It will also complement the P-8 Poseidon. Together, the two aircraft replace the aging P-3C Orion.

Specs include a full day’s worth of flight, an altitude limit over 10 miles, and an operational range of 8,200 nautical miles. The Navy’s program of record states that the service will field 68 aircraft.

First Triton Squadron Stationed in Guam

In addition to being stationed in Guam, Tritons will also be based in the eastern and western U.S., a location in the Middle East and in Sicily, Italy, Navy leaders said.

The Triton UAS is an intelligence, surveillance, reconnaissance drone with specially configured maritime sensors and radar systems. The 45 foot-long, 32,000-pound aircraft has a wingspan of 131 feet.
