The Elbit Systems’ Autonomous Towed Howitzer Ordnance System (ATHOS) is a long-range 155mm/52 calibre gun. The ATHOS has been field-tested for accuracy, stability and reliability during moving and firing manoeuvres and is based on in¬service systems and components.
ATHOS is a fully autonomous and manoeuvrable system. It is capable of a range of 40km and utilises a self-propelled capability and automatic laying mode. It is integrated with fully-computerized systems, achieving automatic control, accurate navigation and target acquisition. When deployed in the battlefield, the ATHOS can manoeuvre itself using its own diesel engine and special hydraulic-driven road wheels, which are also ideal for shoot-and scoot positioning. The hydraulic system enables a team of seven crew members or less to easily deploy the ATHOS within minutes.
The ATHOS utilizes inertial navigation and aiming systems -including a GPS and an onboard firing computer as part of its autonomous capabilities. The gun laying is performed using the INS without any external reference point. The laying system can be slaved to the computer to achieve automatic laying.
The ATHOS is designed to operate under harsh environmental conditions, using all qualified 155mm ammunition in useworldwide. To ease the crew’s workload and enhance gun performance, the ATHOS is equipped with an ammunition loader that dramatically reduces the physical effort needed to operate the gun.
Ammunition Loading System
The ATHOS automated ammunition loading system consists of a loading tray, a ramming mechanism and a crane with a projectile carrier. The system supports a range of firing rates:
Burst rate 3 rounds in 30 seconds
Intense rate 12 rounds in 3 minutes
Sustained rate 42 rounds in 60 minutes
