Voilà des info sur le A129 navalisé que j'ai trouver récemment
Agusta has also proposed a navalized Mangusta, known as the "A-129 Antiship" and referred to as the "Gannet" in some sources, with nose-mounted radar; an Elettronica "electronic support measures (ESM / emitter targeting)" system; chaff dispeners; and armament including antiship missiles, such as two Marte 2s or four Sea Skuas.
