Poster submarine amphion class royal navy

The Amphion Class, sometimes referred to as Class A, is a class of submarines in the Royal Navy, the last to be built during World War II.

Only 16 submarines have been completed out of the 46 originally planned. They were originally designed to replace S-Class and T-Class that were too slow and unable to dive deep enough to be adapted to the deep waters of the Pacific.

Their manufacture was made fast with a hull fully welded and fabricated in sections. Each submarine released was completed in about 8 months (compared to the 15 months of the T-class).

He now had efficient air conditioning for the Far East.

After the war, the units in completion received substantial technical modifications. Like the T-class survivors, they were equipped with a Schnorchel's mast, radar that could be used in periscope immersion and a night periscope to respond to their new missions in response to the Cold War of the early years. 1950.

A redesign was carried out between 1955 and 1960 with new profiling of the bow (front), the removal of deck guns and external torpedo tubes, to improve speed and make them quieter to Soviet sonars.

They served for nearly three decades in the service of the Royal Navy Submarine Service and gradually replaced by the Porpoise class and the Oberon class.

An example of this class, the HMS Alliance can still be seen at the Royal Navy Submarine Museum in Gosport.
