El canguro es el símbolo de una especie de proyecto USA-Australia para esto:
The Decoy Launching System (DLS) Mk 53 (NULKA) is a rapid response Active Expendable Decoy (AED) System capable of providing highly effective defense for ships of cruiser size and below against modern radar homing anti-ship missiles. Nulka is being developed in cooperation with Australia (in the Australian Aboriginal dialect, "Nulka" means "be quick!").
Deployment
Nulka is slated to be installed on
* SPRUANCE (DD-963)-class destroyers,
* ARLEIGH BURKE (DDG-51)-class destroyers
* TICONDEROGA (CG-47)-class cruisers
* WHIDBEY ISLAND (LSD-41)-class dock landing
* SAN ANTONIO (LPD-17)-class amphibious assault
* 21st Century Surface Combatant (SC-21) class
Y el buque en cuestión encontrado en "defensetalk.com"
