Argentine Instalación de Tiro Berreta (Trashy Firing Platform), 1982.
The Argentine forces stationed in the Islands were suffering daily bombardment from British Ships at night, and since the Air Force could not attack the ships at darkness, there was no defensive weapon capable of dealing with this threat. The Argentine High Command decided that an EXOCET MM-38 launcher should be installed on the Islands as a land-based Anti-Ship defense. This launcher could be found on some Argentine Navy ships, the problem was with removing the launcher (And all it's systems) to be used on Land, this could take up to two months.
The idea was not discarded however, a group of naval servicemen started to work on an alternative way in Puerto Belgrano. Their idea was to "fool" the missile, reprogramming the whole system so that the missile can work "as if it's on the ship". By using cables, batteries, signals, the engineers slowly managed to fool the missile and so far, ITB was a succes. Then they had to build a launching station with two tubes for the missiles, also with it's own power source (It is said that it was from the 30's), using the materials they had at their disposal, ITB was ready.
It was sent to the Islands with an Air Force Hercules along with all it's components, when ITB made it to the Islands it was decided to install it at night, fearing that the Kelpers would inform the British about this new weapon. Another problem was the lack of a radar, the Army provided them with a Radar not made for this kind of operation, yet the men had to improvise again, it was all they had.
By tracking British ships for several nights, they managed to determine the path of a British vessel, every day navigating trough the same path. On 12 June, 1982, under the cover of darkness, ITB fired an Exocet missile on a British ship, after a moment an explosion could be seen at the distance, a hit.
It was HMS Glamorgan, the missile was being tracked by the Glamorgan crew, the Captain made a turn to avoid getting hit in the ship's side, instead he made Exocet hit the deck by the port Seacat launcher and then exploded. 14 sailors died and about 22 were wounded, HMS Glamorgan, which was one of the ships involved in heavy bombardment of Argentine positions, was put of out action.
