of 33 feet (10.1 m) and a draught
of 12 in 5 in (3.78 m). She was powered by Parsons
geared steam turbine
s, driving two shafts, which developed a total of 34000 shp and gave a maximum speed of 36 knots (19.6 m/s). Steam for the turbines was provided by three Admiralty 3-drum water-tube boiler
s. Grenade carried a maximum of 470 long tons (477.5 t) of fuel oil
that gave her a range of 5530 nautical miles (10,241.6 km) at 15 knots (8.2 m/s). The ship's complement was 137 officers and men in peacetime.
The ship mounted four 45-calibre
4.7-inch (120 mm) Mark IX guns
in single mounts. For anti-aircraft
defence Grenade had two quadruple Mark I mounts for the 0.5 inch Vickers Mark III
machine gun
. She was fitted with two above-water quadruple torpedo tube
mounts for 21 inches (53 cm)
torpedoes. One depth charge
rail and two throwers were fitted; 20 depth charges were originally carried, but this increased to 35 shortly after the war began.
in Glasgow

on 3 October 1934, launched on 12 November 1935 and completed on 28 March 1936. Excluding government-furnished equipment like the armament, the ship cost £252,560.Adjusted for inflation to 20 pounds, £. She was assigned to the 1st Destroyer Flotilla of the Mediterranean Fleet upon commissioning. Grenade was given a post-completion overhaul in Malta between 20 March and 24 April 1937. After returning home to give her crew leave and be refitted in Chatham Dockyard
between 27 May and July 1938, the ship was then briefly transferred to the Red Sea
in October 1938.
When World War II
began in September 1939, Grenade was in Alexandria
, but she, and her entire flotilla, was transferred to the Western Approaches Command
at Plymouth
in October. On 7 November she collided with her flotilla leader
, and her repairs were not completed until 9 December. During the next several months she was assigned to contraband
control duties in the Downs
. She, and her sister ship
, , rescued 117 survivors from Grenville after the latter ship struck a mine
on 19 January 1940. The ship was refitted in London between 27 January and 27 February, but was struck by the ocean liner
on 27 February and was only temporarily repaired there. Grenade received permanent repairs in Harwich
from 2 March to 3 April and was assigned to Home Fleet at Scapa Flow
after their completion. When the British received word that the Germans were preparing to invade Norway
on 7/8 April, Grenade was part of the escort of Convoy ON25 and was recalled, along with the rest of the escort, to join the Home Fleet. The ship, and the destroyer , escorted the oil tanker
British Lady to Flakstadøya
in the Lofoten Islands where a refuelling and repair base was being set up to support British naval operations in northern Norway. For the rest of the month Grenade escorted the battleship
and the aircraft carrier
in Norwegian waters. The ship provided cover during the evacuation of British and French troops from Namsos
in early May and tied up to the to rescue survivors after the latter's forward magazine
had been hit by a bomb from a Junkers Ju 87 dive bomber
and exploded on 3 May. Four men on Grenade were wounded by splinters from near misses during this time and she rescued 36 sailors, but twenty of them died of their wounds before the ship reached Scapa Flow on 5 May.
Grenade was then transferred to the English Channel
and collided with the anti-submarine
trawler
Clayton Wyke on 14 May in heavy fog. Her repairs were completed at Sheerness Dockyard on 25 May. During the initial stages of the evacuation from Dunkirk the ship provided cover in the northern part of the Channel to the evacuation forces and rescued 33 survivors on 28 May from SS Abukir, which had been torpedoed by an E-boat
. She made one trip to Dunkirk during the night of 28/29 May and was caught in Dunkirk harbour by German Stukas during the following day. Grenade was hit by two bombs which set her afire and killed 14 sailors and mortally wounded another four men. The ship was cast off from her berth, in case she sank there, and then drifted into the harbour channel. The trawler John Cattling towed Grenade over to the west side of the outer harbour where her magazines exploded later that evening.
