Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.

History

HMS Jervis, J-class Flotilla Leader was a destroyer of the J class. Commissioned just before the outbreak of war, Jervis saw extensive service in the Mediterranean and Atlantic theatres. She participated in multiple major engagements in the Mediterranean, and later participated in the D-Day landings of 1944. Jervis was retired at the end of the war, and later scrapped. She was highly decorated and received 13 battle honours for her service in the Second World War. Jervis also gained a reputation for being extremely lucky, as she never lost a single crew member during her 5 and a half years of service.[1][2]

Design and Development

HMS Jervis on sea trials, early 1939.

The Jervis, as a member of the J class, was designed as a smaller follow-up to the preceding Tribal-class destroyers. Being smaller, the J class had a stronger balance between guns and torpedo armament, compared to the "gunship-style" Tribal-class destroyers. Jervis, in particular, was fitted with additional command space to accommodate the Flotilla commander. Jervis displaced 2600 tons, and was capable of 36 knots (66 km/h).[1] Her main armament consisted of six 4.7-inch (120 mm) guns in three dual turrets, two mounted at the bow and one at the stern.[1] She also carried numerous anti-aircraft defences as well as eight 533 mm torpedo tubes in two quad-mounts.[1]

Jervis was laid down in mid-1937 and was launched in September of 1938. She was completed and commissioned in May of 1939, just months before the outbreak of the Second World War.

Service history

Following her completion and commissioning, the Jervis served as the flagship of the 7th Destroyer fleet. She first served as a patrol vessel in the North Sea, hunting for axis blockade runners; however, she collided with a freighter in March of 1940 and was dry docked for repairs.[2] Once the repairs were completed, she was assigned to the Mediterranean squadron, where she saw extensive service. She escorted convoys to Malta, participated in shore bombardment missions, and provided screening services to the British Mediterranean fleet.[2]

In 1941, Jervis served in the Battle of Cape Matapan, where she sank the crippled Italian cruiser Zara and boarded Zara's sister ship Pola. She later participated in the battles of Crete and Sirte, where she managed to survive undamaged despite heavy allied losses.[2] Later on, she was immobilized for six weeks by an Italian manned torpedo.[1][2]

In 1944, Jervis was reassigned to the British Atlantic fleet, and provided fire support for the forces landing at Gold Beach for the D-Day landings. She was thereafter decommissioned for a refit which gave her additional anti-aircraft protection.[2] She returned to the Mediterranean after her recommissioning, and served as a patrol ship as World War II drew to a close. Following the end of the war, she was laid up in reserve and used by the cadets as a training ship. After being used for explosive tests, Jervis was given to the shipbreakers for scrap.[2]

Jervis is known as an extremely lucky ship: despite being active for almost the entirety of the war and having served in 13 major naval engagements, she never lost a single crew member.[1] In fact, she was one of just two J-class ships to survive the war. She received 13 battle honours for her service during the Second World War, making her one of the most highly decorated British warships in modern history.[1][2]
