Challenging submarine navigation

If you expect maritime surveillance and control,

underwater surveillance and control is essential

• Antisubmarine capacity

• Mine clearance on SLOC

• Underwater surveillance on

specific points

OPV / CPV / Light frigate Design

Safety at sea and protection of maritime interest :

Capability to cover large maritime areas operate numerous platforms

OPV / CPV / light frigate appears as a current appropriate response

for maritime area control

COST EffectiveMEDIUM / LOW WEAPONS capability

FULL INFORMATION capability

ANTI SUBMARINE CAPACITY Submarine view :

ASW assets are not targets

ASW assets make difficulty or prevent to achieve the mission

ASW assets view :

More important to be sure where the submarine is not,

than where the sub is.

Ensure SAFE and SECURE PANORAMIC sanctuary around the platform

Surveillance, Deterrence,

Area Denial, Anti-Access, barrier

Pressure on the submarine, Harassment,

Self-protection,

The goal is to prevent the submarine from achieving its mission

Use of weapons from the OPV / light frigate is not mandatory : torpedoes could be better

operated from Helicopter, or others ASW assets if collaborative action group is in action.

OPV / CPV light frigate ASW Role :

• Capability of training and operations with friendly submarine (essential ! )

LOW FREQUENCY ACTIVE SONAR

• To reach same detection range :

• MF/HF source level must be higher (absorption of sea water)

• MF/HF Array will be bigger ( weight, size, draught, more complex to install)

• From same source level :

• MF/HF sonar requires directional search mode to reach same range, but loses

panoramic optimal range

• LF offers lower reverberation returns levels (enhancing better false alarm rate reduction and

discrimination) provided by a large effective bandwidth.

• LF provides larger sonar coverage with better reflection on the sea bottom ( very useful in

common South-East Asia negative sound velocity profile and shallow waters )

Maximize panoramic active detection range under the constraint of weight, size, price

NOISE COMPLIANT ACTIVE SONAR

OPV/CPV & light frigate, not typically ASW designed, are not particularly

acoustically stealth.

• Because of radiated-noise, it is hard to expect acoustic advantage or

surprise against submarine, but in accordance with ASW role.

• Because of ambient-noise, due to high density of sea lanes of

communication, it is necessary to use active sonar

• Active sonar, especially with “adaptive beamforming” processing, is much

less sensible to self-noise

Thales Underwater Systems

Roughly 20 km PASSIVE detection range against Go fast.

Most of the time beyond the radar/optical horizon

• SONAR as complementary equipment, added to Optical, radar, IR

sensors , able to open new capability in establishing maritime

surface picture ( warning, surveillance, intel and proof collect),

over-horizon passive detection ;

FULL INFO CAPABILITY – SURFACE - Acoustic sensor added value

Optical, radar, IR are common sensors for maritime surveillance design,

but have physical and meteorogical limitation.

The use of SONAR opens new domain,

is combined with RADAR and OPTRONIC for Warning, surveillance, Intel and proof collect, is efficient in Self-protection ( Torpedo alert , obstacle avoidance).

MINE CLEARANCE ON SLOC

o Used as a common harbour and naval base

entrance,fairways safety equipment :

o Clearance of approaches

o Stongly valuable for economic maritime

development

o Low investment regarding durability of
