“We are focused on providing low-risk, long-range artillery capability, enhanced human effectiveness through manned and unmanned teaming solutions, and finding ways to ‘innovate at the round’ to address deficits in range, capacity, and survivability of current systems,” Mike added. “We believe there is a window to help the Army meet its needs with the proven platforms and technology we offer.”

Highlights of Hanwha’s show display include:

K9A2 Self-Propelled Howitzer: The 155mm/52-calibre K9A2 Self-Propelled Howitzer (SPH) has a fully automatic handling system, an automatic turret, and an increased rate of fire of 10 rounds per minute at the push of a button, compared to the A1 with a rate of fire of 6 to 8.  At this year’s show, HDUSA will be showcasing the A2 variant—a first for AUSA.

The K9 is the most widely used SPH in the world due to its firepower, high mobility, and survivability. It can engage targets at a range of 40 kilometers with currently available conventional ammunition and has demonstrated a range of 50+ kilometers with various extended projectiles. About 2,000 K9 vehicles, including localized variants, are in production or in service with ten nations, including Poland, Norway, Finland, Estonia, Australia, and Egypt, with the most recent country being Romania.

Modular Charge System: Hanwha’s 155mm Artillery Modular Charge System (MCS) is a Joint Ballistic Memorandum of Understanding (JBMoU)-compliant modular charge designed for use in 39 and 52 caliber gun configurations. The MCS features a clean burning charge that leaves little to no residue, eliminating the need for barrel swabbing between fires; the system is also equipped with high-strength combustible cases that can withstand the demands of rapid firing—both of which contribute to an increased rate of fire.

GRUNT (GRound UNcrewed Transport): The GRound UNcrewed Transport (GRUNT) is a 6×6 hybrid electric vehicle designed to support infantry operations, such as ammunition transport, medical evacuation, reconnaissance, and fire support. The vehicle can drive up to 290 kilometers when fully charged and has a maximum payload of more than 900 kilograms, offering a significant improvement in combat support and maneuvering capabilities. The GRUNT is an evolution from the legacy Arion-SMET, offering enhanced capability.

Wheeled Howitzer: Hanwha Aerospace is developing a wheeled Mobile Howitzer (MH) utilizing K9A2 turret technology, an adapter/mounting ring with stabilizers, and a heavy (8×8) truck platform. The MH is in the prototyping phase and will use a 52-calibre armament common with the K9A1/2, have a fully automated firing sequence, and be paired with a wheeled resupply vehicle utilizing the same ammunition transfer technology found in the K10 Ammunition Resupply Vehicle (ARV). With this new platform underway, Hanwha’s customers will have options of tracked and wheeled platforms that offer the same high performance.

Integrated Vetronics System: Hanwha Systems, an affiliate of Hanwha Aerospace, will display its integrated Vetronics System (IVS), which functions as the “brain” and “sensory network” of various ground combat systems such as main battle tanks, armored vehicles, self-propelled howitzers

On September 24, 2024, the US Army declared that it had chosen American Rheinmetall Vehicles LLC (ARV) and HDT Expeditionary Systems Inc. to supply unmanned ground vehicle (UGV) prototypes for additional assessment in order to meet its needs for the Small Multipurpose Equipment Transporter Increment II (S-MET II).

The S-MET is intended to provide the small unit with a means to carry a variety of different loads to enhance its sustainability and capability for more autonomous operations. An earlier S-MET I from General Dynamics Land Systems has been in field service with Army light infantry units. Army program officials have stated that S-MET II’s requirements reflect lessons learned from use of this earlier UGV.

S-MET II’s primary users will be Infantry Brigade Combat Teams, Explosive Ordnance Disposal, and Security Force Assistance Brigades. The S-MET is essentially a self-powered platform that can be controlled remotely by a single soldier and accompany the unit across various terrain in all weather conditions.

S-MET II will double the earlier model’s the payload carried to 2000 lbs (910 kg), offer increased exportable power, have a lower noise signature, increased reliability, to include wireless mesh communications, and worldwide grid charging. Equipping the platform to enable modern mission payloads like Unmanned Air Systems and communications equipment are key additional capabilities.

S-MET II is also to be a modular system with an open architecture that will allow for easier and cost-effective upgrading.

Each company has received a US$22 million contract to provide eight S-MET II prototypes for development testing.

• ARV has proposed a variation of its Mission Master SP (Silent Partner). It uses a low-signature electric motor for stealth and agility and is designed for forward resupply or as a sensor or weapon carrier. The Mission Master is being supplied to the Japanese Seld Defence Forces and was recently demonstrated to the US Marines.
• HDT has offered its WOLF with a 2200 lb capacity in a rugger 6 X 6 vehicle. It has a range of 200 miles with self-charging hybrid-electric drivetrain.

Following testing the Army will place a production contract which is scheduled for the end of late Fiscal Year 2027 (between July and September 2024). The announced Army Acquisition Objective is for up to 2,195 systems.

In today’s battlefield environment, electronic warfare (EW) and advanced electronic systems play a vital role in mission success. Whether friendly or adversarial, thousands of signals — ranging from comms and radar to jamming and attack — are scattered throughout the environment and encountered every second, impacting any electronic equipment that passes through. These signals are generated across multiple domains, including ground, sea, sub-surface, air and space. It is more important than ever to be prepared for this complex electromagnetic environment and be able to identify, locate and act on signals to execute missions effectively.

To prepare for real-world operations in EW-contested environments, platforms can be tested on the range or via EW/electromagnetic environment simulation. EW simulation is a highly advanced and constantly evolving capability that enables testing in a lab setting, without the need for an aircraft to leave the ground. The key to effective EW simulation is being able to accurately replicate the phase, amplitude and time of arrival of signals to the system under test enabling it to identify the types of threats being simulated. Having the ability to simulate these complex signals quickly and accurately so they replicate real-world physics allows a large percentage of testing to take place in a lab environment, before the aircraft is tested on a range where it will encounter signals generated by real emitters.

Alongside the convenience of not having to leave the lab to test a system, cost-savings is another major benefit of EW simulation. Taking into account the fuel, equipment, maintenance, etc. required to test on the range, it can cost tens of thousands of dollars hourly to conduct testing operations. EW simulation is a considerably cheaper method to prepare vehicles in a lab, leading to significant cost-savings when performing testing that does not require operation in a range.

While EW simulation has been around for quite some time, the introduction of new threats and the ever-growing complexity of the electromagnetic environment demands simultaneous advancement and improvement of EW simulation capabilities. Textron Systems’ state of the art A²PATS® system addresses this challenge, offering highly sophisticated and accurate electromagnetic environment simulation capabilities for radar warning receivers (RWRs), electronic support measure suites, fusion engines and communication sensors. The system’s direct port architecture enables extremely precise phase, amplitude and time of arrival replication of radio frequency (RF) signals and covers low band frequencies as low as 500 kilohertz all the way up to millimeter frequencies as high as 40 gigahertz.

One of the many advanced capabilities the A²PATS system offers is simultaneous simulation of communication intelligence (COMINT) and electronic intelligence (ELINT) signals. Having the ability to simulate both COMINT and ELINT signals at the same time allows you to model and stimulate an entire integrated air defense system (IADS) opposed to just a single part of the chain like a SAM site or a ground control station. Textron Systems continues to upgrade the digital processing chain for next generation advanced threat modeling, number of loadable signals and higher pulse density requirements to support the needs of the future.

The A²PATS simulator’s open-architecture design makes it modular in nature and enables scaling based on the needs of the customer. Textron Systems offers desktop, mini, single and multi-cabinet configurations, enabling system output up to 16 million pulses per second (MPPS) per port, with the capability to increase as needed. The A²PATS system can be complemented with several user tools such as emulators, scoring tools and PDW injectors for additional confidence, expansion and support.

With signals across the battlespace evolving at a rapid pace, it is more vital than ever to invest in testing and training systems that can keep you prepared for current and future missions. Trust Textron Systems’ A²PATS and its simulation capabilities to give you confidence in your mission while navigating today’s congested electromagnetic environment.
