Once a ship had been built and launched she then had to be out-fitted, and then complete sea trials
before being handed over to her new owners, as always in the case of a ship for the Royal Navy she would then have to complete her commissioning trials before being excepted into the senior service.
HMS MASTIFF was to have a very short life at sea as a ship of the Royal Navy, she had the mis-fortune to set off a sea mine that had been laid in the river Thames
H.M.S. "Mastiff" was an order from the Admiralty for a second of class armed trawler of the "Dog Class" She was designed and built by Henry Robb Shipbuilders with an obvious eye to the coming hostilities that developed into World War II.
She was an improved version of this class and a bit larger than her sister ship "Basset" she was launched on 17th February 1938.
She had a displacement of 520 tons with a length overall of 150 feet and beam of 27 feet and 6 inches. She had a top speed of 12 knots and a crew compliment of around 35. Being armed initially with a 4 inch gun for'd and 2 x .303 machine guns.
She struck a mine in the Thames estuary and was lost on 20 November 1939, only two months after war had been declared.
