SAAB

Saab develops high technology underwater

systems for a wide range of applications that

allow Armed Forces to enhance and extend

their operational capabilities.

Saab’s Underwater Systems are designed to

build situational awareness, provide decision

superiority and enable response to any

given situation.

THE DOUBLE EAGLE SYSTEM

The Double Eagle System uses a modular

approach to provide flexible systems for

MCM operations. The System provides a

hydro-dynamically stable, highly reliable

system with exceptional performance and

low life cycle cost.

There are three main configurations:

• Mine Reconnaissance, both remotely

controlled or autonomously performed

• Mine Disposal

• REA

Navies around the world use the Double

Eagle on many types of ships. It has also

been adapted to Craft Of Opportunities

(COOP), where Double Eagle is housed in

a container that is easily installed on almost

any type of ship.

DOUBLE EAGLE FAMILY > MINE HUNTING

MINE RECONNAISSANCE

Traditional mine reconnaissance is performed

by an MCM ship provided with hull mounted

or towed sonar. The new concept is to integrate

sonar on the powerful Double Eagle

running several hundred metres ahead of the

ship, remotely or autonomously operated.

This arrangement not only improves ship and

crew safety, but also enhances the performance

of the sonar, as it is possible to vary both

its depth and viewing angle of the target.

Based on the well-proven Double Eagle

control system, a high-power vehicle has

been developed to provide extreme power

enabling utilization of the Double Eagle in

strong current environments.

RAPID ENVIRONMENT ASSESSMENT

The Double Eagle SAROV performs autonomous

mine reconnaissance missions over vast

areas, gathering vital environmental data for

planning MCM missions, identifying mine-like

looking objects and sending positional data

via cable or radio.

MINE DISPOSAL

In mine disposal configuration, the Double

Eagle is fitted with location sonar and a

disposal charge or a mine sniper, a one shot

mine destructor vehicle.

Its inherent precision manoeuvring capability

allows the Double Eagle to place a charge

close to the mine or launch the mine sniper

with high precision for destruction of the

mine.

This is achieved with the minimum of noise

and without complicated control systems

that add weight, size, complexity, and cost

to the system.

DOUBLE EAGLE MK II/III SYSTEM

Standard System

• Double Eagle Mk II or Mk III includes all controls

to manoeuvre the vehicle.

• Operator Control Board, OCB.

• Display Unit, DU 14” monitor mounted in a 19” rack.

• Electronic Unit, EU.

The heart of the system with interfaces to all other units.

• Surface Application Computer, SAC. Data acquisition,

communication, presentation of data.

• Power Converter Unit, PCU.

A static converter that creates power for the vehicle from ship

power, includes insulation monitoring with circuit breaker.

• ATC Winch. Automatic tension control.

• Cradle or trolley for deck handling.

• Launch and Retrieval System, LARS.

The tool is used in conjunction with a sea-crane onboard the ship,

for automatic release or retrieval of the vehicle.

• Portable Operators Control Board, POCB.

DOUBLE EAGLE PVDS SYSTEM

The Double Eagle PVDS system is equipped with a rotatable,

forward looking sonar that significantly enhances the detection

range of sea mines and yields virtually unlimited endurance.

DOUBLE EAGLE SAROV SYSTEM

The SAROV enhances the capabilities of the Double Eagle family of

ROVs and creates a hybrid AUV/ROV. The addition of autonomous

operation and underwater docking capability enables the SAROV to

be operated both with and without a tether thereby increasing range

and versatility.
