ARA (Armada Argentina/Argentina Navy) San Juan. 1983 Diesel Electric, recently serviced. https://en.m.wikipedia.org/wiki/ARA_San_Juan



I read about that service somewhere, they basically cut the boat in half to replace the engines and then welded it back together.


>According to Minister of Defense Agustin Rossi, the MLU cost some 100 million Argentine Pesos (12.4 million dollars) and comprised more than 500,000 work hours in which the boat was cut in half and had its four MTU engines and batteries replaced. The MLU was under way at CINAR since August 2007. He blamed the delay on the lack of funds and qualified labor.

> Rossi called the re-delivery an important milestone for Argentina, as the state had lost its ability to repair submarines following the previous Domecq Garcia shipyards being disbanded.[1]

Distinct lack of details; though the article says crew of 37 when every current article about it missing states 44.

edit: The lack of maintenance facilities is worrying, though it sounds like the overhaul has created a grannies broom; there's not much of the original sub left.

I've heard of Theseus's Ship, and grandfather's axe - granny's broom is a new one to me.


I noticed, and enjoyed, that variation too.

A few of my software products have gone through multiple frameworks and rewrites, but from the user's point of view they appear to have remained one evolving entity. My phone/personal-digital-assistant also has kept its name for 21 years, but has gone through a series of reincarnations.


The saying is usually Trigger's Broom, after the character in Only Fools And Horses.

It's not that unusual in submarine refits to cut the boat in half and slot in an entire new section!
