UAE Navy, Saab and UUVs

The command of the UAE Navy is said to be going ahead with a project to buy underwater surveillance systems.
Tactical Report has prepared a 282-word report to shed more light on the subject and tell what about the contacts with Saab of Sweden on the project.

With its modular design, Saab's AUV62-MR offers a level of flexibility that is superior to conventional alternatives such as vessels with a hull-mounted or towed sensor.

As a complete, autonomous system fully equipped for military purposes, the AUV62-MR is the modern choice for Mine Countermeasures (MCM). By removing men from the minefield, the vehicle provides a safe underwater solution that is capable of adapting to changing threats during naval operations.

THE SAFEST CHOICE FOR MCM

Mine reconnaissance has historically been an extremely time and resource intensive activity for militaries. AUV62-MR operates autonomously, performing long-term mine reconnaissance missions with greater speed. With its modular design, Saab's AUV62-MR offers a level of flexibility that is superior to conventional alternatives such as vessels with a hull-mounted or towed sensor.

COVERT OPERATIONS

Effective reconnaissance and surveillance of underwater areas is crucial to thesuccess of a military invasion by sea.

Equipped with cutting-edge information gathering capabilities, such as highly accurate positioning, the AUV62-MR can perform surveillance and reconnaissance of the underwater area immediately after deployment.

Its ability to operate autonomously from a submarine, combined with its inherent long-term endurance capability, enables the AUV62-MR to perform the whole mission covertly.

MULTI-PLATFORM CAPABILITY

The AUV62-MR can be launched from multiple platforms due to its flexibility and adaptable components. It is usually recovered the same way, whether by ship, submarine or shore.

The vehicle was intentionally designed to resemble a Heavyweight Torpedo (HWT), with the same mechanical and electrical interfaces, meaning there is no need for modification or integration if it is used on a submarine.

The AUV62-MR can therefore be launched directly from an HWT tube, enabling fast,effective deployment of the vehicle.

For surface ship recovery, a unique docking device retrieves the vehicle from the water and winches it back to the launch chute.

A specially designed ROV – the SUBROV – is used to recover the vehicle when used on a submarine.

Swath width 2x200 m (SAS, synthetic aperture processing)

2x500 m (REA and bathymetric focused multi-beam processing)

Sonar resolution < 4x4 cm (combined with optical identification)

The Double Eagle SAROV's state-of-the-art design and sophisticated sensors allow it to provide multifunctional capabilities for MCM operators. The system is hydro-dynamically stable and highly reliable, providing both exceptional performance and low lifecycle cost.

Combining the features of ROVs and AUVs makes the Double Eagle SAROV a versatile vehicle suitable for a variety of missions, including:

  • Underwater survey missions
  • REA missions
  • Identification operations
  • Mine disposal operations
  • Detection of underwater objects

DOUBLE EAGLE SAROV PACKAGE

The Double Eagle SAROV package enhances the capabilities of the Double Eagle family of ROVs and creates an ROV/AUV hybrid.

 

The addition of autonomous operation and underwater docking capability means that the Double Eagle SAROV can be operated both with and without a tether, thereby increasing its range and versatility.

 

Double Eagle SAROV comes in two main configurations:

  • Mine reconnaissance – performed both remotely and autonomously
  • Mine disposal
