AH-64E Apache teams with two UAVs to identify, attack target
4 February 2021
An Apache AH-64E, a Shadow RQ-7BV2 Block 3 and a MQ-1C Gray Eagle Extended Range successfully worked together to carry out an air-to-ground missile attack at Dugway Proving Ground in October.
An Apache pilot took control of the RQ-7’s sensor payload for reconnaissance and lased a target. Then, the MQ-1C fired a laser-guided AGM-114 Hellfire, successfully hitting the ground target from 15,000ft. The trio of aircraft repeated the manned-unmanned demonstration a few days later, hitting a ground target with a Small Glide Munition.
The US Army has been conducting manned-unmanned teaming for years using the AH-64 and MQ-1C, but it had not previously incorporated a third UAV. Since the Bell OH-58D Kiowa Warrior scout helicopter was retired in 2017, the Apache and Gray Eagle have handled reconnaissance and attack missions.
The recent three-way manned-unmanned teaming test is meant to demonstrate part of the US Army’s version of Joint All-Domain Command & Control.
The new manned-unmanned teaming capabilities required software modifications on the different radios of the AH-64, MQ-1C and RQ-7 to allow collaboration on the same waveform. The US Army says it has not yet determined a schedule to roll out the capability to its fleet.
The ranges at which the AH-64 and MQ-1C can collaborate are increasing. As part of the recent Dugway Proving Ground demonstrations, “the data link range between the Apache and the Gray Eagle operated at a much farther distance than before, providing the opportunity for over-the-horizon reconnaissance”, the US Army says. It declines to disclose the data link range, but says the demonstration “spanned over 30 miles”.
In 2020, General Atomics used an MQ-1C to identify and produce targeting coordinates of “radar emitters” using a L3Harris Nino communications intelligence system and its in-house Lynx synthetic aperture radar system. The company said the Nino is capable of sniffing out emitters up to 135nm (250km) away. It is not clear at what range targeting coordinates can be produced.
In 2020, the US Army demonstrated launching the Area-I Altius 600 air-launched effect from an airborne UH-60 Black Hawk, which was acting as a stand-in for FARA. General Atomics also launched an Altius 600 from its MQ-1C last year. The Altius 600 has a range of 238nm and could be used as a loitering munition. In 2019, the service demonstrated launching Rafael’s anti-armor Spike Non-Line-of-Sight missile from an AH-64. That missile has a range of 17.3nm.
The US Army is aiming to incorporate the Apache’s APG-78 Longbow fire control radar, and whatever radar succeeds it on FARA, into manned-unmanned teaming in the future, says Benjamin. The latest version of the Longbow radar has a detection range of 8.64nm and can simultaneously search, detect, locate and classify up to 256 moving and stationary targets, says the Northrop Grumman-Lockheed Martin joint venture that manufactures it.
Benjamin says one of the biggest challenges with expanding manned-unmanned teaming to new aircraft is not strictly technological. Helicopter pilots and weapons officers can suffer from information overload with so many data feeds and attack options available. The US Army is trying to figure out ways to make information easier to digest. “How do we make it much easier for that operator to do their primary mission? And also secondary missions?,” says Benjamin.
...
It is still not clear what the upward limit of manned-unmanned teaming operations will be, he says. “There are definitely fields of thought within the aviation community that you could control multiple UAVs,” says Benjamin. “What that number is – is it three? Is it six? Is it 12? Is it 100? – it’s still being assessed.”

HAL unveils ambitious air-teaming system centred on Tejas
4 February 2021
...air-teaming system that will incorporate the Tejas LCA with various unmanned assets... the effort, designated Combat Air Teaming System (CATS).
Work on CATS started in the second half of 2018 and began in earnest in late 2019-early 2020. Preliminary design work has been completed. The Tejas twin-seat trainer is being optimised as part of a manned-unmanned teaming concept, as this variant still has some growth potential. Work is now being done to define the requirements for a future cockpit for the type capable of handling the workload.
As part of CATS, future variants of the Tejas Mk-1A will act as a ‘Mothership for Air teaming eXploitation’ (MAX) and will be modified with additional command and control interfaces for this purpose.
Several other elements are included. The CATS Warrior is a low-observable unmanned wingman, which is controlled from CATS MAX. A full-size CATS Warrior mock-up displayed at the Aero India show also featured ASRAAM missile, designated NGCCM (New Generation Close Combat Missile) in Indian air force service.
Another element involves swarming UAVs called CATS ALFA (Air Launched Flexible Assets), which can be launched from CATS-MAX and work as a swarm of weaponised drones, as well as the CATS Hunter multi-purpose weapons carriage system.
A high-altitude, long-endurance UAV is also being considered as part of CATS.
Much of the work is being done by HAL, which is also partnering with Indian start-ups to deliver the programme. Scale models are expected to begin testing in the near future. Since the Tejas lacks an operational datalink , HAL is looking to integrate an indigenous datalink that is being tested on the Hawk-i, a locally modified version of the Hawk 132.
The powerplant selected for the CATS Warrior is HAL’s PTAE-7, which will be uprated with FADEC controls and new long-life parts. The PTAE-7 was originally developed in the late 1980s as a powerplant for target drones.

Specifically designed for single-user operation, Ninox 40 is a micro tactical, cost-effective drone system, featuring an encapsulated drone and control unit. Weighing under 250g - within regulatory limitations - it is lightweight enough to be incorporated into the soldier's vest and carried on-person during combat. Ninox 40 has a flight endurance of up to 40 minutes, extensive ISTAR capabilities, day and night camera for enhanced situational awareness, automatic tracking, and can be launched on the move and from under cover, even in harsh environmental conditions.
Northrop Grumman has demonstrated the ability to conduct wide-area multistatic acoustic search for a submarine using its MQ-8C Fire Scout unmanned helicopter.
The demonstration was conducted in the Pacific Ocean in October 2020. A manned Bell 407, which was acting as a surrogate for the MQ-8C, lifted off from Carlsbad airport in California carrying G-size sonobuoys, a receiver and processor made by Ultra of the UK.
Northrop says the MQ-8C’s large fuel tank allows it to conduct large-area multistatic acoustic searches for submarines better than manned helicopters, such as the Sikorsky MH-60R Seahawk, which have shorter ranges. The MQ-8C can carry a payload of 40 sonobuoys and using its 12h flight endurance can search an area 86.9nm from its mothership, says Northrop. The MH-60R has a flight endurance of 3.3h and carries 25 sonobuoys.
The MQ-8C’s sonobuoy payload would usually consist of 29 acoustic sonobuoys, plus eight spares and three bathythermograph buoys.

DARPA’s multi-modal ‘LongShot’ missile programme awards design contracts
9 February 2021
...has awarded preliminary design contracts for its LongShot programme, a concept that envisions an air-launched unmanned air vehicle (UAV) carrying and firing multiple smaller air-to-air missiles.
Contracts were awarded to General Atomics, Lockheed Martin and Northrop Grumman for preliminary Phase I design work. The value of the contracts was not announced, though DARPA requested $22 million in its fiscal year 2021 budget proposal.
The LongShot programme aims to develop a UAV that can be carried and launched by fighter or bomber aircraft. That UAV would then fly ahead of its manned carrier and launch air-to-air missiles to shoot down enemy aircraft. DARPA believes a multi-modal system would have advantages over current air combat technologies.
“An air system using multi-modal propulsion could capitalize upon a slower speed, higher fuel-efficient air vehicle for ingress, while retaining highly energetic air-to-air missiles for endgame target engagements,”. There are two key benefits to this method, DARPA says:
“First, the weapon system will have a much-increased range over their legacy counterparts for transit to an engagement zone,” it says.
“Second, launching air-to-air missiles closer to the adversary increases energy in terminal flight, reduces reaction time, and increases probability of kill.”
It is not clear how many air-to-air missiles LongShot would carry, though the number is at least two. The research agency wants an “air-launched vehicle capable of employing current and advanced air-to-air weapons”.
DARPA has not said whether it intends to recover the LongShot UAV or whether it would be disposable. Some similar attritable UAVs in development and target drones come with parachutes instead of landing gear. Target drones with parachutes are sometimes designed to land on a crushable cone in their nose.
In later phases of the programme, DARPA says it plans to fund construction and first flight of a full-scale LongShot demonstrator. The UAV ought to be air launched and “capable of controlled flight, before, during, and after weapon ejection under operational conditions”, it says.
