Due to a bombing raid in August 1940 the main Naval Anti-Submarine training base HMS Osprey at Portsmouth was badly damaged. For once wisdom came to their Lordships and it was decided that training should take place in a less vulnerable place. Campbletown in Scotland fitted the bill so the Grammar School was requisitioned and a new set of pupils were moved in, Navy personnel training on ASDIC. HMS Nimrod came into being. Due to the large influx of personnel a new housing estate was also requisitioned for accommodation for HMS Nimrod, this section was given the name of Nimrod- B.
In a very short time Campbeltown was soon to become a Military Base of a great size. It would have in the end HMS Nimrod Anti-submarine training, HMS Landrail Fleet Air Arm, a Rescue Tug Base also Air/Sea Rescue, plus a boom defence unit.
Due to the large size of the ASDIC training personnel HMS Seahawk at Ardrishaig quickly came into being as a tender to HMS Nimrod.
