Brazen displaced 1360LT at standard load and 1790LT at deep load. The ship had an overall length of 323feet, a beam of 32feet and a draught of 12feet. She was powered by Parsons geared steam turbines, driving two shafts, which developed a total of 34000shp and gave a maximum speed of 35kn. Steam for the turbines was provided by three Admiralty 3-drum boilers. Brazen carried a maximum of 390LT of fuel oil that gave her a range of 4800nmi at .[1] The ship's complement was 134 officers and ratings, although it increased to 142 during wartime.[2]
The ship mounted four 45-calibre QF 4.7-inch Mk IX guns in single mounts. For anti-aircraft (AA) defence, Brazen had two 40mm QF 2-pounder Mk II AA guns mounted on a platform between her funnels. She was fitted with two above-water quadruple torpedo tube mounts for 21inches torpedoes.[2] 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.[3]
The ship was ordered on 22 March 1929 from Palmers Shipbuilding and Iron Company at Hebburn under the 1928 Naval Programme. She was laid down on 22 July 1929, and launched on 25 July 1930,[4] as the seventh RN ship to carry this name.[5] Brazen was completed on 8 April 1931 at a cost of £220,342, excluding items supplied by the Admiralty such as guns, ammunition and communications equipment.[6] After her commissioning, she was assigned to the 4th Destroyer Flotilla with the Mediterranean Fleet until the end of 1935. The ship received a refit at Devonport from August to October 1933 and another at Malta a few months later. Brazen was assigned to the Home Fleet in 1936 and participated in the effort to rescue the crew of the submarine which had sunk during sea trials on 1 June 1939.[7]
The ship was reassigned to the 19th Destroyer Flotilla in August, shortly before World War II began. She spent the next seven months escorting convoys and patrolling in the English Channel and the North Sea. On 13 October, Brazen rescued three survivors from which had sunk after striking a mine a few hours earlier. The ship, together with the destroyer, assumed the escort of Convoy HN12 after the destroyer had been sunk by . Later that day she rescued some survivors from the Norwegian merchant ship Sangstad.[8] Brazen escorted the capital ships of the Home Fleet as they sortied into the North Sea on 7 April and continued that duty for the next several weeks.[9] The ship was detached to escort a troop convoy to Namsos on 13 April and sank two days later with the destroyer near Harstad, Norway.[10] The two destroyers rescued 41 of the submarine's crew. Brazen escorted several more convoys to and from Norway over the next several weeks.[8]
On 30 May, the ship was en route to Harwich when she struck some submerged wreckage and suffered damage that required five weeks to repair. Brazen was transferred to the 1st Destroyer Flotilla, based at Dover, upon their completion, where she began escorting coastal convoys. Whilst escorting Convoy CW7 on 20 July, during the initial phase of the Battle of Britain, the ship was attacked by German Junkers Ju 87 Stuka dive bombers belonging to II./Sturzkampfgeschwader 1 (Dive Bomber Wing 1—or StG 1).[11] The shock effect from several near misses broke her keel and then she was hit in the engine room. Brazen sank at position 51.0181°N 1.2875°W at 20:40. Only one member of her crew was killed during the attack and her gunners claimed to have shot down three Ju 87s.[8] German records confirm only two losses—both fell to defending British fighter aircraft.[12]
