This is coolbert:
In particular those surface-launched torpedoes of the MU90 variety MOST APPROPRIATE FOR THE ARMED MERCHANTMAN.
"MU90 Surface Launched Lightweight Torpedo - DCNS"
"Its impressive embedded acoustic and dynamic capabilities also allow the use of the weapon in anti-surface missions and, with few adaptations, in anti-torpedo roles."
That MU90 a joint French/Italian venture with many cloned versions existing, INCLUDING A CHINESE KNOCK-OFF!!
That embedded YouTube video particularly impressive. The MU90 is the little torpedo that can!!
THE INCORPORATION OF THE MU90 ALLOW ALMOST ANY MERCHANTMAN TO BECOME A NAVAL HUNTER/KILLER VESSEL WITH SOME EXTRAORDINARY CAPABILITY!
Useful in the anti-submarine warfare [ASW] role exclusively so? NOT able to engage surface vessels. The MU90 warhead a shaped-charge ONLY!
Italian military hardware designers as having been noted by the Soviet defector Suvorov:
"the Italians have very good brains, the brains of great inventors."
Without question, unequivocally so!!
