HMS Moy was a Laird Type River-class destroyer of the Royal Navy. Named after the River Moy in Ireland, she was the first ship to carry this name in the Royal Navy.
She was ordered under the 1903 – 1904 Naval Estimates, laid down on 22 March 1904, at Cammell Laird's shipyard at Birkenhead and launched on 10 November 1904. She was completed in June 1905. Her original armament was to be the same as the turtleback torpedo boat destroyers that preceded her. In 1906 the Admiralty decided to upgrade the armament by landing the five 6-pounder naval guns and shipping three 12-pounder/8 hundredweight (cwt) guns). Two would be mounted abeam at the foc's'le break and the third gun would be mounted on the quarterdeck.
After commissioning she was assigned to the East Coast Destroyer Flotilla of the 1st Fleet and based at Harwich. On 27 April 1908, the Eastern Flotilla departed Harwich for live fire and night manoeuvres. During these exercises HMS Attentive rammed and sank HMS Gala then damaged HMS Ribble. In April 1909 she was assigned to the 3rd Destroyer Flotilla on its formation at Harwich. She remained until displaced by a Beagle-class destroyer by May 1912. She went into reserve assigned to the 5th Destroyer Flotilla of the Second Fleet with a nucleus crew. On 30 August 1912 the Admiralty directed all destroyer classes were to be designated by alpha characters starting with the letter 'A'. The ships of the River class were assigned to the E class. After 30 September 1913, she was known as an E class destroyer and had the letter ‘E’ painted on the hull below the bridge area and on either the fore or aft funnel.[3]
