The SIAC (155/52 APU SBT) is a state of the art 155/52 caliber towed howitzer designed by Santa Barbara Sistemas, a General Dynamics subsidiary with self-propelled capabilities thanks to its integrated APU (Auxiliary Power Unit).This advanced design meets the most demanding requirements of modern field artillery and coastal defense missions. It features rapid deployability, excellent first round hit probability and a swift “shoot and scoot” capability for higher survivability.
The Automatic Gun Laying System (AGLS), the Digital Navigation Aiming and Pointing System (DINAPS) and the Fully Automatic Ramming System (FIRS) are integrated in the SIAC to provide superior performance on the battlefield. The first two can be also integrated in other indirect weapon systems (mortar, rocket launchers, etc.).
Fire Capability
The ballistic computer provides fast fire data for all NATO compatible ammunition and offers ranges of over 40km and up to 60 km. The weapon systems offer maximum burst rates per minute and high MRSI (Multiple Round Simultaneous Impact).
Superb Survivability
The APU provides the SIAC with independent tactical maneuverability enabling it to reach the desired position, regardless of the terrain, and to offer a fast “shoot and scoot” capability.
Extreme Accuracy
SIAC integrates several applications that improve its performance on the battlefield: An Automatic Gun Laying System (AGLS), a Digital Navigation Aiming and Pointing System (DINAPS) and a Fully Automatic Ramming System (FIRS). SIAC also incorporates a Ballistic Computer which provides fast firing data calculations to optimize the ammunition selection. Finally, the SIAC can be integrated within a Command and Control system (C2 to C4ISR).
Coastal Defense
SIAC is suitable for forming part of a net-centric defense solution which integrates multiple weapon systems that can be operated simultaneously. SIAC is a perfect fit for Coastal Defense.
