Path to In-Stride MCM
3/4/2020 3
Current unmanned MCM concept involves a “toolbox” of systems that
each only do a portion of the find-fix-finish process, one step at a
time, to achieve mine disposal – still not a rapid process!
To shorten the clearance timeline and to do all of this unmanned,
automated and in stride, you need: – a sharper sonar picture;
– a smarter sonar
– and an autonomous neutralizer
Raytheon, with its AN/AQS-20C mine hunting sonar and revolutionary
Barracuda mine neutralizer, is moving forward toward making
unmanned, automated in-stride mine clearance a reality!
For rapid unmanned MCM, USV towed sonar and autonomous neutralizer
are the key tools in the MCM toolbox

AN/AQS-20C Mine Hunting Sonar System
Single-pass detection, classification and identification
of mine-like objects from the sea floor to the near surface
High area search rate
Wideband multi-beam forward-looking sonar maximizes the
performance of the system against water column targets
Environmental optimization tools maximize performance
in challenging acoustic environments
Synthetic aperture side look sonars provide detailed imaging
of seabed targets
Built-in automatic detection and classification tools reduce
operator workload
High-resolution Electro-optic Sensor and high-resolution
Acoustic ID Sonars enable in-stride mine identification
Simultaneous volume and bottom coverage with high resolution
SAS greatly improves search efficiency and speed

Raytheon MCM Systems
3/4/2020 7
Raytheon IDS has developed the most innovative and capable MCM systems on the international market
AQS-20C Mine Hunting Sonar – only towed MCM sonar with:
- Forward looking volume array and gap-filler array underneath
- Standard SAS and high resolution SAS (many times resolution of standard SAS) for acoustic
identification capability
- Automatic target recognition capability
**Provides complete coverage of bottom and volume in a single pass**
Barracuda – Micro AUV, semi-autonomous mine neutralizer that allows:
- Untethered mine neutralization from near surface to the sea bed
- Deployment from air and surface craft
Both systems operating together allows for in-stride mine clearance – US Navy Programs of
Record!
AQS-20C technology can be incorporated into AUV systems, and Barracuda could be deployed
from larger AUV systems
Raytheon is working with numerous global industry partners in pursuit of international opportunities
that require a toolbox of MCM systems – Raytheon can create an end to end MCM solution!
Raytheon can provide the best MCM capability available to meet individual
NATO Navy requirements
