ECA GROUP Unveils its Towed Sonar T18-M

: Oct 23, 2018 - : 11:58 am

The ECA Group unveiled its towed sonar, T18-M. Ideal for implementation from a USV, it has the same launching and recovery system (LARS) as well as shared logistics with the A18-M.

 

The T18-M is an A18-M on which the nose is replaced by one equipped with rudders and a towing point and thruster was removed at rear. Subsequent free space makes it possible to integrate a longer interferometric SAS sonar antenna to achieve the detection performance at highest speeds. It inherits, on the one hand, the A18-M’s positioning and navigation qualities and, on the other hand, the complete integration with ECA Group’s UMISTM systems and in particular the UMISOFTTM C2 suite.

 

Like a conventional towed sonar, the T18-M meets all mine warfare recommendations (especially the detection or classification phases). Like the A18-M, it is produced in accordance with the STANAG 1364 to minimize acoustic and magnetic signatures and to be able to fly near mines without triggering them.

 

The T18-M is equipped with the AUV A18-M’s inertial navigation system (FOG – INS + DVL) which, together with the USBL system of the USV, ensures very precise positioning in the minefield.

 

Conventional towed sonars receive their energy from the towline when the T18-M is self-powered.
