This year's AVUSI will feature a number of unmanned vehicles from underwater versions to aircraft

Bluefin Robotics Knifefish

In late 2011, Bluefin Robotics was awarded a subcontract through General Dynamics Advanced Information Systems to engineer and manufacture the Navy's Surface Mine Countermeasure Unmanned Underwater Vehicle. Dubbed Knifefish, the specialised Bluefin-21 UUV will fill the requirement as a main feature of the Littoral Combat Ship mission package. The company recently announced it had completed the preliminary design review for the system. Two Knifefish and their launch and recovery equipment will be featured on each ship. The contract holds options for up to 10 more UUVs.

Boeing Insitu RQ-21 Integrator

Developed as a follow-on to the Boeing Insitu's ScanEagle remotely operated aircraft, the RQ-21 Integrator is expected to fill the US Navy and US Marine Corps' small tactical unmanned aircraft system (STUAS) tier II requirement. An initial two-year developmental contract was awarded in 2010.

The USMC is testing the small, unmanned machine in limited user trials in the Californian desert at 29 Palm. Two machines are currently being tested there. In USMC service, the Integrator will replace the Scan Eagle services that the marines have previously contracted. For the USN and USMC, the Integrator is particularly useful because of its ability to operate from ships. It is pneumatically launched and recovered via a 'sky hook'. The Marines have around eight aircraft, and plan to acquire 100 by 2017.

Boeing Phantom Eye

Developed by Boeing, the Phantom Eye is an experimental unmanned aircraft designed to fly at high altitude for extended periods of time. Unlike most unmanned aircraft, the Phantom Eye is powered by hydrogen gas instead of fossil fuels such as JP-8 or gasoline. The company claims that using hydrogen fuel makes the aircraft far more efficient than conventionally fuelled rivals. Uniquely, Boeing adapted Ford truck engines to power the aircraft.

The Phantom Eye first flew earlier this year at Edwards AFB, California, but while Boeing says most of the flight went smoothly, the aircraft made a hard landing. The aircraft suffered some damage, which upon visual inspection did not appear to be particularly significant. Boeing has traced the root cause of the crash to the design of the nose landing-gear.

Boeing has brought in F/A-18 engineers from St Louis, Missouri, to help fix the Phantom Eye's problems.

DARPS/Boston Dynamics LS3

DARPA and Boston Dynamics developed the Legged Squad Support System, a four-legged, dog-like robot that uses computer vision to 'see' the path in front of it and follow a human through varied terrain, in 2012. The unmanned ground vehicle is modelled after Boston Dynamics' Big Dog robot. Testing for the LS3 included hauling 400 pounds of payload across a 20-mile track for 24 hours, all without refuelling. Testing started in July and is expected to run for 18 months. Although the final system isn't expected to be in the field with the warfighter for another four years, DARPA officials say that having a robot that can "think" at the level of a trained animal is something that could greatly benefit the military down the road.

  • Payload: 400lb
  • Range: 20 miles

FLIR SeaFLIR

FLIR makes infrared and other heat-sensing capabilities for the military and commercial customers. Its sensors have many practical applications, and have become part of the payload for both manned and unmanned systems.

In May 2012, the company announced that it received a $17.9 million delivery order from the US Navy Expeditionary Combat Command (NECC) for its SeaFLIR maritime imaging systems. The company says SeaFLIR is a long-range, gyro-stabilised, thermal imager that provides high-resolution infrared images in daylight as well as in total darkness. The Navy is expected to use it on patrol boats.

General Atomics Predator C Avenger

General Atomics' latest and most capable offering is the Predator C Avenger, a jet-powered and greatly upsized version of the iconic Predator. Two of the aircraft are making envelope expansion test flights, the second aircraft being more representative of a production model. Production has been ramped up to one aircraft every nine months, and while the US Air Force has purchased one for evaluation, General Atomics declined to say where the others may be headed. Several nations have expressed interest in the aircraft, and it is widely considered a frontrunner for a US Navy contest to build an unmanned combat aircraft.

Lockheed Martin Squad Mission Support System

Lockheed Martin's Squad Mission Support System is the largest unmanned ground vehicle ever deployed with US forces. It gained that distinction in late 2011, when two US Army units began evaluating the machines in Afghanistan after the system won the Army's Project Workhorse competition. The devices have been subjected to much abuse and have proven popular with the soldiers, Lockheed Martin says. The company has internally funded Block 0 and Block 1 variants of the SMSS, with the later models featuring smaller sensor packages and changes to make them quieter in the field.

  • Weight: 4,000lb
  • Payload: 1,000+lb
  • Vertical step: 22in
  • Range: 300mi on road, 200 mi. cross-country
  • Gap: 27in

MacroUSA Armadillo

MacroUSA's Armadillo ground robot can be wheeled or tracked and has a 5-pound payload capacity. It can be dropped up to 8 feet or thrown as far as 33 feet and still conduct its mission. The system recently underwent a trial by the National Institute of Standards and Technology as part of a review of commercial, off-the-shelf technology. The Joint Improvised Explosive Defeat Organization plans to buy as many as 100 of them and is testing the robot in Afghanistan. Canadian robot maker Allen-Vanguard recently signed on as a distributor for MacroUSA's line of small unmanned ground vehicles.

Northrop Grumman MQ-4C Triton Broad Area Maritime Surveillance

The US Navy officially rolled-out the Northrop Grumman MQ-4C Triton Broad Area Maritime Surveillance aircraft on 14 June, 2012 in Palmdale, California. The aircraft is based on the US Air Force's RQ-4B Global Hawk, but the USN variant has an airframe modified with better all-weather capability - the most important of which is wing de-icing. It is slated to become the first unmanned aircraft to receive an airborne sense-and-avoid capability.

For its maritime surveillance mission, the aircraft will be fitted with a 360° active electronically scanned array radar and a Raytheon MTS-B electro-optical/infrared camera ball. It also will have electronic support measures and an automatic identification system to track ships. By fiscal year 2019, the USN hopes to add a signals intelligence capability to the Triton.

The USN will eventually buy a total of 68 aircraft, but it will fly only 20 at any given time. That will be enough for five orbits around the globe, but the USN is considering placing the majority of those around the Pacific.

 
 
  • Wingspan: 130.9ft
  • Weight: 32,250lb

  • Payload: 5,600lb

Northrop Grumman MQ-8B Fire Scout

Despite several recent incidents, including the loss of one aircraft at sea and another to gunfire over Libya, the Northrop Grumman Fire Scout has emerged as the rotary wing unmanned aerial vehicle of choice for the US military, by far the largest customer of such aircraft. Seven are operationally deployed - three to northeast Afghanistan for land-based operations and four aboard the frigate USS Klackring, headed for the Horn of Africa. The prototype successor, FireX, which ports the same software onto a Bell 407 airframe, has begun flying again after a time on the ground. The US Navy expects to order 28 FireX's, although it has signed officially for only two thus far.

  • Rotor diameter: 8.4m (27.4ft)
  • Length: 7.3m (23.9ft)
  • Weight: 1,428kg (3,150lb)
  • Endurance: 8h
  • Cruise speed: 115kts
  • Payload capacity: 272kg (600lb)

Northrop Grumman X-47B Unmanned Combat Air System-Demonstrator (UCAS-D)

The objective of the US Navy's Unmanned Combat Air System-Demonstrator (UCAS-D) is to prove that a tactical fighter-sized unmanned aircraft with a stealthy platform can safely take-off and land onboard a USN aircraft carrier. The X-47B is also slated to demonstrate that such an aircraft can safely aerial refuel autonomously using either the USN probe-and-drogue system or the US Air Force's flying boom method.

The X-47B started flying last year at Edwards AFB, California, and successfully completed initial flight trials at the desert base. Recently, the first of two demonstrators was moved to the Navy's flight test centre in Patuxent River, Maryland. For the next year or so, the aircraft will conduct carrier-suitability trials. The USN hopes to conduct its first carrier landing with the X-47B onboard the aircraft carrier USS Harry S Truman in about a year's time.

If the UCAS-D proves to be successful, the technology will form the basis for the USN's follow-on Unmanned Carrier-Launched Surveillance and Strike aircraft.

QinetiQ North America Dragon Runner 10

Dragon Runner 10 joined the QinetiQ North America fleet of UGVs in 2011. Based on the design of the original Dragon Runner robot, this 'little brother' weighs in at less than 10 pounds, making it ideal for military and first responder use. Dragon Runner 10 is a throwable micro UGV, as QinetiQ engineers demonstrated last year at AUVSI's Unmanned Systems North America in Washington DC. Since then, the Joint Improvised Explosive Device Defeat Organization has ordered more than 100 of the systems in response to a Joint Urgent Operations Needs Statement for lightweight, throwable robots. The $5.3 million contract extended through spring 2012.
