Sidon (P 259)
|
Refit completed HMS Sidon re-commissioned into the 2nd Submarine Squadron, based at Portland for submarine and anti-submarine training
In "A Submariner's story" commissioning engineer officer Joel C E Blamey tells how the first trial dive out of the yard ended up with Sidon plunging down with a severe bow down angle striking the shingle bottom at 158 feet. A dockyard modification had caused a complete loss of the telemotor pressure resulting in the loss of control of the main vents and hydroplanes and other equipment. While quite frightening no serious damage was done. |
