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
