The Extorp..

WATERS NEAR GUAM (Mar. 07, 2016) The Arleigh Burke-Class guided-missile destroyer USS McCampbell (DDG-85) fires an MK-54 exercise torpedo (EXTORP) over the port side during an anti-submarine warfare (ASW) event as part of MULTI SAIL 2016. MULTI SAIL is a bilateral training exercise aimed at interoperability between the U.S. and Japanese forces. This exercise builds interoperability and benefits from realistic, shared training, enhancing our ability to work together to confront any contingency. McCampbell is on patrol in the 7th fleet of operations in support of security and stability in the Indo-Asia-Pacific.

Long a staple of ASW training, exercise/recoverable torpedoes (extorps/rextorps) have been around for the Mk44, Mk46, Mk48, Mk50 and 54 variants and are typically the reworked warshot fish in which the explosive is replaced with an electronic signaling and guidance package that records the position of the device for data analysis after the exercise, and various signaling devices that help locate the torpedo in the water for recovery afterward.

They are pretty brightly marked, and colorful.

Almost always retrieved after tests or exercises, they are refurbished and shot again, sometimes dozens of times.

If not recovered by retrieval personnel for some reason, they have a ‘phone home’ marking on the casing should a random skin diver or fisherman chance upon one.

About laststandonzombieisland

Let me introduce myself. I am a bit of a conflict junkie. I am fascinated by war and warfare, assassination, personal protection and weaponry ranging from spud guns and flame throwers to thermonuclear bombs and Soviet-trained Ebola monkeys. In short, if it’s violent or a tool to create violence it is kind of my thing. I have written a few thousand articles on the dry encyclopedia side for such websites as GUNS.com, Univesity of Guns, Outdoor Hub, History Times, Big Game Hunter, Glock Forum, Firearms Talk.com, and Combat Forums; as well as for print publications like England Expects, and Strike First Strike Fast. Several magazines such as Sea Classics, Military Historian and Collector, Mississippi Sportsman and Warship International have carried my pieces. Additionally I am on staff as a naval consultant and writer for Eye Spy Intelligence Magazine. Currently I am working on several book projects including an alternative history novel about the US-German War of 1916, and a biography of Southern gadfly and soldier of fortune Bennett Doty. My first novel, about the coming zombie apocalypse was released in 2012 by Necro Publications and can be found at Amazon.com as was the prequel, Chimera-44. I am currently working on book two of that series: "Pirates of the Zombie Coast." In my day job I am a contractor for the US federal government in what could best be described as the ‘Force Protection’ field. In this I am an NRA-certified firearms, and less-than-lethal combat instructor.
